+ <para>
+ The clock framework defines programming interfaces to support
+ software management of the system clock tree.
+ This framework is widely used with System-On-Chip (SOC) platforms
+ to support power management and various devices which may need
+ custom clock rates.
+ Note that these "clocks" don't relate to timekeeping or real
+ time clocks (RTCs), each of which have separate frameworks.
+ These <structname>struct clk</structname> instances may be used
+ to manage for example a 96 MHz signal that is used to shift bits
+ into and out of peripherals or busses, or otherwise trigger
+ synchronous state machine transitions in system hardware.
+ </para>
+
+ <para>
+ Power management is supported by explicit software clock gating:
+ unused clocks are disabled, so the system doesn't waste power
+ changing the state of transistors that aren't in active use.
+ On some systems this may be backed by hardware clock gating,
+ where clocks are gated without being disabled in software.
+ Sections of chips that are powered but not clocked may be able
+ to retain their last state.
+ This low power state is often called a <emphasis>retention
+ mode</emphasis>.
+ This mode still incurs leakage currents, especially with finer
+ circuit geometries, but for CMOS circuits power is mostly used
+ by clocked state changes.
+ </para>
+
+ <para>
+ Power-aware drivers only enable their clocks when the device
+ they manage is in active use. Also, system sleep states often
+ differ according to which clock domains are active: while a
+ "standby" state may allow wakeup from several active domains, a
+ "mem" (suspend-to-RAM) state may require a more wholesale shutdown
+ of clocks derived from higher speed PLLs and oscillators, limiting
+ the number of possible wakeup event sources. A driver's suspend
+ method may need to be aware of system-specific clock constraints
+ on the target sleep state.
+ </para>
+
+ <para>
+ Some platforms support programmable clock generators. These
+ can be used by external chips of various kinds, such as other
+ CPUs, multimedia codecs, and devices with strict requirements

+ The PCI Express Port Bus Driver Guide HOWTO
+ Tom L Nguyen tom.l.nguyen@intel.com
+ 11/03/2004
+
+1. About this guide
+
+This guide describes the basics of the PCI Express Port Bus driver
+and provides information on how to enable the service drivers to
+register/unregister with the PCI Express Port Bus Driver.
+
+2. Copyright 2004 Intel Corporation
+
+3. What is the PCI Express Port Bus Driver
+
+A PCI Express Port is a logical PCI-PCI Bridge structure. There
+are two types of PCI Express Port: the Root Port and the Switch
+Port. The Root Port originates a PCI Express link from a PCI Express
+Root Complex and the Switch Port connects PCI Express links to
+internal logical PCI buses. The Switch Port, which has its secondary
+bus representing the switch's internal routing logic, is called the
+switch's Upstream Port. The switch's Downstream Port is bridging from
+switch's internal routing bus to a bus representing the downstream
+PCI Express link from the PCI Express Switch.
+
+A PCI Express Port can provide up to four distinct functions,
+referred to in this document as services, depending on its port type.
+PCI Express Port's services include native hotplug support (HP),
+power management event support (PME), advanced error reporting
+support (AER), and virtual channel support (VC). These services may
+be handled by a single complex driver or be individually distributed
+and handled by corresponding service drivers.
+
+4. Why use the PCI Express Port Bus Driver?
+
+In existing Linux kernels, the Linux Device Driver Model allows a
+physical device to be handled by only a single driver. The PCI
+Express Port is a PCI-PCI Bridge device with multiple distinct
+services. To maintain a clean and simple solution each service
+may have its own software service driver. In this case several
+service drivers will compete for a single PCI-PCI Bridge device.
+For example, if the PCI Express Root Port native hotplug service
+driver is loaded first, it claims a PCI-PCI Bridge Root Port. The
+kernel therefore does not load other service drivers for that Root
+Port. In other words, it is impossible to have multiple service
+drivers load and run on a PCI-PCI Bridge device simultaneously
+using the current driver model.
+
+To enable multiple service drivers running simultaneously requires
+having a PCI Express Port Bus driver, which manages all populated
+PCI Express Ports and distributes all provided service requests
+to the corresponding service drivers as required. Some key
+advantages of using the PCI Express Port Bus driver are listed below:
+
+ - Allow multiple service drivers to run simultaneously on
+ a PCI-PCI Bridge Port device.
+
+ - Allow service drivers implemented in an independent
+ staged approach.
+
+ - Allow one service driver to run on multiple PCI-PCI Bridge
+ Port devices.
+
+ - Manage and distribute resources of a PCI-PCI Bridge Port
+ device to requested service drivers.
+
+5. Configuring the PCI Express Port Bus Driver vs. Service Drivers
+
+5.1 Including the PCI Express Port Bus Driver Support into the Kernel
+
+Including the PCI Express Port Bus driver depends on whether the PCI
+Express support is included in the kernel config. The kernel will
+automatically include the PCI Express Port Bus driver as a kernel
+driver when the PCI Express support is enabled in the kernel.
+
+5.2 Enabling Service Driver Support
+
+PCI device drivers are implemented based on Linux Device Driver Model.
+All service drivers are PCI device drivers. As discussed above, it is
+impossible to load any service driver once the kernel has loaded the
+PCI Express Port Bus Driver. To meet the PCI Express Port Bus Driver
+Model requires some minimal changes on existing service drivers that
+imposes no impact on the functionality of existing service drivers.
+
+A service driver is required to use the two APIs shown below to
+register its service with the PCI Express Port Bus driver (see
+section 5.2.1 & 5.2.2). It is important that a service driver
+initializes the pcie_port_service_driver data structure, included in
+header file /include/linux/pcieport_if.h, before calling these APIs.
+Failure to do so will result an identity mismatch, which prevents
+the PCI Express Port Bus driver from loading a service driver.
+
+5.2.1 pcie_port_service_register
+
+int pcie_port_service_register(struct pcie_port_service_driver *new)
+
+This API replaces the Linux Driver Model's pci_module_init API. A
+service driver should always calls pcie_port_service_register at
+module init. Note that after service driver being loaded, calls
+such as pci_enable_device(dev) and pci_set_master(dev) are no longer
+necessary since these calls are executed by the PCI Port Bus driver.
+
+5.2.2 pcie_port_service_unregister
+
+void pcie_port_service_unregister(struct pcie_port_service_driver *new)
+
+pcie_port_service_unregister replaces the Linux Driver Model's
+pci_unregister_driver. It's always called by service driver when a
+module exits.
+
+5.2.3 Sample Code
+
+Below is sample service driver code to initialize the port service
+driver data structure.
+
+static struct pcie_port_service_id service_id[] = { {
+ .vendor = PCI_ANY_ID,
+ .device = PCI_ANY_ID,
+ .port_type = PCIE_RC_PORT,
+ .service_type = PCIE_PORT_SERVICE_AER,
+ }, { /* end: all zeroes */ }
+};
+
+static struct pcie_port_service_driver root_aerdrv = {
+ .name = (char *)device_name,
+ .id_table = &service_id[0],
+
+ .probe = aerdrv_load,
+ .remove = aerdrv_unload,
+
+ .suspend = aerdrv_suspend,
+ .resume = aerdrv_resume,
+};
+
+Below is a sample code for registering/unregistering a service
+driver.
+
+static int __init aerdrv_service_init(void)
+{
+ int retval = 0;
+
+ retval = pcie_port_service_register(&root_aerdrv);
+ if (!retval) {
+ /*
+ * FIX ME
+ */
+ }
+ return retval;
+}
+
+static void __exit aerdrv_service_exit(void)
+{
+ pcie_port_service_unregister(&root_aerdrv);
+}
+
+module_init(aerdrv_service_init);
+module_exit(aerdrv_service_exit);
+
+6. Possible Resource Conflicts
+
+Since all service drivers of a PCI-PCI Bridge Port device are
+allowed to run simultaneously, below lists a few of possible resource
+conflicts with proposed solutions.
+
+6.1 MSI Vector Resource
+
+The MSI capability structure enables a device software driver to call
+pci_enable_msi to request MSI based interrupts. Once MSI interrupts
+are enabled on a device, it stays in this mode until a device driver
+calls pci_disable_msi to disable MSI interrupts and revert back to
+INTx emulation mode. Since service drivers of the same PCI-PCI Bridge
+port share the same physical device, if an individual service driver
+calls pci_enable_msi/pci_disable_msi it may result unpredictable
+behavior. For example, two service drivers run simultaneously on the
+same physical Root Port. Both service drivers call pci_enable_msi to
+request MSI based interrupts. A service driver may not know whether
+any other service drivers have run on this Root Port. If either one
+of them calls pci_disable_msi, it puts the other service driver
+in a wrong interrupt mode.
+
+To avoid this situation all service drivers are not permitted to
+switch interrupt mode on its device. The PCI Express Port Bus driver
+is responsible for determining the interrupt mode and this should be
+transparent to service drivers. Service drivers need to know only
+the vector IRQ assigned to the field irq of struct pcie_device, which
+is passed in when the PCI Express Port Bus driver probes each service
+driver. Service drivers should use (struct pcie_device*)dev->irq to
+call request_irq/free_irq. In addition, the interrupt mode is stored
+in the field interrupt_mode of struct pcie_device.
+
+6.2 MSI-X Vector Resources
+
+Similar to the MSI a device driver for an MSI-X capable device can
+call pci_enable_msix to request MSI-X interrupts. All service drivers
+are not permitted to switch interrupt mode on its device. The PCI
+Express Port Bus driver is responsible for determining the interrupt
+mode and this should be transparent to service drivers. Any attempt
+by service driver to call pci_enable_msix/pci_disable_msix may
+result unpredictable behavior. Service drivers should use
+(struct pcie_device*)dev->irq and call request_irq/free_irq.
+
+6.3 PCI Memory/IO Mapped Regions
+
+Service drivers for PCI Express Power Management (PME), Advanced
+Error Reporting (AER), Hot-Plug (HP) and Virtual Channel (VC) access
+PCI configuration space on the PCI Express port. In all cases the
+registers accessed are independent of each other. This patch assumes
+that all service drivers will be well behaved and not overwrite
+other service driver's configuration settings.
+
+6.4 PCI Config Registers
+
+Each service driver runs its PCI config operations on its own
+capability structure except the PCI Express capability structure, in
+which Root Control register and Device Control register are shared
+between PME and AER. This patch assumes that all service drivers
+will be well behaved and not overwrite other service driver's
+configuration settings.

+
+ How To Write Linux PCI Drivers
+
+ by Martin Mares <mj@ucw.cz> on 07-Feb-2000
+ updated by Grant Grundler <grundler@parisc-linux.org> on 23-Dec-2006
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The world of PCI is vast and full of (mostly unpleasant) surprises.
+Since each CPU architecture implements different chip-sets and PCI devices
+have different requirements (erm, "features"), the result is the PCI support
+in the Linux kernel is not as trivial as one would wish. This short paper
+tries to introduce all potential driver authors to Linux APIs for
+PCI device drivers.
+
+A more complete resource is the third edition of "Linux Device Drivers"
+by Jonathan Corbet, Alessandro Rubini, and Greg Kroah-Hartman.
+LDD3 is available for free (under Creative Commons License) from:
+
+ http://lwn.net/Kernel/LDD3/
+
+However, keep in mind that all documents are subject to "bit rot".
+Refer to the source code if things are not working as described here.

+
+
+
+0. Structure of PCI drivers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+PCI drivers "discover" PCI devices in a system via pci_register_driver().
+Actually, it's the other way around. When the PCI generic code discovers
+a new device, the driver with a matching "description" will be notified.
+Details on this below.
+
+pci_register_driver() leaves most of the probing for devices to
+the PCI layer and supports online insertion/removal of devices [thus
+supporting hot-pluggable PCI, CardBus, and Express-Card in a single driver].
+pci_register_driver() call requires passing in a table of function
+pointers and thus dictates the high level structure of a driver.
+
+Once the driver knows about a PCI device and takes ownership, the
+driver generally needs to perform the following initialization:
+
+ Enable the device
+ Request MMIO/IOP resources
+ Set the DMA mask size (for both coherent and streaming DMA)
+ Allocate and initialize shared control data (pci_allocate_coherent())
+ Access device configuration space (if needed)
+ Register IRQ handler (request_irq())
+ Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip)
+ Enable DMA/processing engines
+
+When done using the device, and perhaps the module needs to be unloaded,
+the driver needs to take the follow steps:
+ Disable the device from generating IRQs
+ Release the IRQ (free_irq())
+ Stop all DMA activity
+ Release DMA buffers (both streaming and coherent)
+ Unregister from other subsystems (e.g. scsi or netdev)
+ Release MMIO/IOP resources
+ Disable the device
+
+Most of these topics are covered in the following sections.
+For the rest look at LDD3 or <linux/pci.h> .
+
+If the PCI subsystem is not configured (CONFIG_PCI is not set), most of
+the PCI functions described below are defined as inline functions either
+completely empty or just returning an appropriate error codes to avoid
+lots of ifdefs in the drivers.
+
+
+
+1. pci_register_driver() call
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+PCI device drivers call pci_register_driver() during their
+initialization with a pointer to a structure describing the driver
+(struct pci_driver):
+
+ field name Description
+ ---------- ------------------------------------------------------
+ id_table Pointer to table of device ID's the driver is
+ interested in. Most drivers should export this
+ table using MODULE_DEVICE_TABLE(pci,...).
+
+ probe This probing function gets called (during execution
+ of pci_register_driver() for already existing
+ devices or later if a new device gets inserted) for
+ all PCI devices which match the ID table and are not
+ "owned" by the other drivers yet. This function gets
+ passed a "struct pci_dev *" for each device whose
+ entry in the ID table matches the device. The probe
+ function returns zero when the driver chooses to
+ take "ownership" of the device or an error code
+ (negative number) otherwise.
+ The probe function always gets called from process
+ context, so it can sleep.
+
+ remove The remove() function gets called whenever a device
+ being handled by this driver is removed (either during
+ deregistration of the driver or when it's manually
+ pulled out of a hot-pluggable slot).
+ The remove function always gets called from process
+ context, so it can sleep.
+
+ suspend Put device into low power state.
+ suspend_late Put device into low power state.
+
+ resume_early Wake device from low power state.
+ resume Wake device from low power state.
+
+ (Please see Documentation/power/pci.txt for descriptions
+ of PCI Power Management and the related functions.)
+
+ shutdown Hook into reboot_notifier_list (kernel/sys.c).
+ Intended to stop any idling DMA operations.
+ Useful for enabling wake-on-lan (NIC) or changing
+ the power state of a device before reboot.
+ e.g. drivers/net/e100.c.
+
+ err_handler See Documentation/PCI/pci-error-recovery.txt
+
+
+The ID table is an array of struct pci_device_id entries ending with an
+all-zero entry; use of the macro DEFINE_PCI_DEVICE_TABLE is the preferred
+method of declaring the table. Each entry consists of:
+
+ vendor,device Vendor and device ID to match (or PCI_ANY_ID)
+
+ subvendor, Subsystem vendor and device ID to match (or PCI_ANY_ID)
+ subdevice,
+
+ class Device class, subclass, and "interface" to match.
+ See Appendix D of the PCI Local Bus Spec or
+ include/linux/pci_ids.h for a full list of classes.
+ Most drivers do not need to specify class/class_mask
+ as vendor/device is normally sufficient.
+
+ class_mask limit which sub-fields of the class field are compared.
+ See drivers/scsi/sym53c8xx_2/ for example of usage.
+
+ driver_data Data private to the driver.
+ Most drivers don't need to use driver_data field.
+ Best practice is to use driver_data as an index
+ into a static list of equivalent device types,
+ instead of using it as a pointer.
+
+
+Most drivers only need PCI_DEVICE() or PCI_DEVICE_CLASS() to set up
+a pci_device_id table.
+
+New PCI IDs may be added to a device driver pci_ids table at runtime
+as shown below:
+
+echo "vendor device subvendor subdevice class class_mask driver_data" > \
+/sys/bus/pci/drivers/{driver}/new_id
+
+All fields are passed in as hexadecimal values (no leading 0x).
+The vendor and device fields are mandatory, the others are optional. Users
+need pass only as many optional fields as necessary:
+ o subvendor and subdevice fields default to PCI_ANY_ID (FFFFFFFF)
+ o class and classmask fields default to 0
+ o driver_data defaults to 0UL.
+
+Once added, the driver probe routine will be invoked for any unclaimed
+PCI devices listed in its (newly updated) pci_ids list.
+
+When the driver exits, it just calls pci_unregister_driver() and the PCI layer
+automatically calls the remove hook for all devices handled by the driver.
+
+
+1.1 "Attributes" for driver functions/data
+
+Please mark the initialization and cleanup functions where appropriate
+(the corresponding macros are defined in <linux/init.h>):
+
+ __init Initialization code. Thrown away after the driver
+ initializes.
+ __exit Exit code. Ignored for non-modular drivers.
+
+
+ __devinit Device initialization code.
+ Identical to __init if the kernel is not compiled
+ with CONFIG_HOTPLUG, normal function otherwise.
+ __devexit The same for __exit.
+
+Tips on when/where to use the above attributes:
+ o The module_init()/module_exit() functions (and all
+ initialization functions called _only_ from these)
+ should be marked __init/__exit.
+
+ o Do not mark the struct pci_driver.
+
+ o The ID table array should be marked __devinitconst; this is done
+ automatically if the table is declared with DEFINE_PCI_DEVICE_TABLE().
+
+ o The probe() and remove() functions should be marked __devinit
+ and __devexit respectively. All initialization functions
+ exclusively called by the probe() routine, can be marked __devinit.
+ Ditto for remove() and __devexit.
+
+ o If mydriver_remove() is marked with __devexit(), then all address
+ references to mydriver_remove must use __devexit_p(mydriver_remove)
+ (in the struct pci_driver declaration for example).
+ __devexit_p() will generate the function name _or_ NULL if the
+ function will be discarded. For an example, see drivers/net/tg3.c.
+
+ o Do NOT mark a function if you are not sure which mark to use.
+ Better to not mark the function than mark the function wrong.
+
+
+
+2. How to find PCI devices manually
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+PCI drivers should have a really good reason for not using the
+pci_register_driver() interface to search for PCI devices.
+The main reason PCI devices are controlled by multiple drivers
+is because one PCI device implements several different HW services.
+E.g. combined serial/parallel port/floppy controller.
+
+A manual search may be performed using the following constructs:
+
+Searching by vendor and device ID:
+
+ struct pci_dev *dev = NULL;
+ while (dev = pci_get_device(VENDOR_ID, DEVICE_ID, dev))
+ configure_device(dev);
+
+Searching by class ID (iterate in a similar way):
+
+ pci_get_class(CLASS_ID, dev)
+
+Searching by both vendor/device and subsystem vendor/device ID:
+
+ pci_get_subsys(VENDOR_ID,DEVICE_ID, SUBSYS_VENDOR_ID, SUBSYS_DEVICE_ID, dev).
+
+You can use the constant PCI_ANY_ID as a wildcard replacement for
+VENDOR_ID or DEVICE_ID. This allows searching for any device from a
+specific vendor, for example.
+
+These functions are hotplug-safe. They increment the reference count on
+the pci_dev that they return. You must eventually (possibly at module unload)
+decrement the reference count on these devices by calling pci_dev_put().
+
+
+
+3. Device Initialization Steps
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As noted in the introduction, most PCI drivers need the following steps
+for device initialization:
+
+ Enable the device
+ Request MMIO/IOP resources
+ Set the DMA mask size (for both coherent and streaming DMA)
+ Allocate and initialize shared control data (pci_allocate_coherent())
+ Access device configuration space (if needed)
+ Register IRQ handler (request_irq())
+ Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip)
+ Enable DMA/processing engines.
+
+The driver can access PCI config space registers at any time.
+(Well, almost. When running BIST, config space can go away...but
+that will just result in a PCI Bus Master Abort and config reads
+will return garbage).
+
+
+3.1 Enable the PCI device
+~~~~~~~~~~~~~~~~~~~~~~~~~
+Before touching any device registers, the driver needs to enable
+the PCI device by calling pci_enable_device(). This will:
+ o wake up the device if it was in suspended state,
+ o allocate I/O and memory regions of the device (if BIOS did not),
+ o allocate an IRQ (if BIOS did not).
+
+NOTE: pci_enable_device() can fail! Check the return value.
+
+[ OS BUG: we don't check resource allocations before enabling those
+ resources. The sequence would make more sense if we called
+ pci_request_resources() before calling pci_enable_device().
+ Currently, the device drivers can't detect the bug when when two
+ devices have been allocated the same range. This is not a common
+ problem and unlikely to get fixed soon.
+
+ This has been discussed before but not changed as of 2.6.19:
+ http://lkml.org/lkml/2006/3/2/194
+]
+
+pci_set_master() will enable DMA by setting the bus master bit
+in the PCI_COMMAND register. It also fixes the latency timer value if
+it's set to something bogus by the BIOS.
+
+If the PCI device can use the PCI Memory-Write-Invalidate transaction,
+call pci_set_mwi(). This enables the PCI_COMMAND bit for Mem-Wr-Inval
+and also ensures that the cache line size register is set correctly.
+Check the return value of pci_set_mwi() as not all architectures
+or chip-sets may support Memory-Write-Invalidate. Alternatively,
+if Mem-Wr-Inval would be nice to have but is not required, call
+pci_try_set_mwi() to have the system do its best effort at enabling
+Mem-Wr-Inval.
+
+
+3.2 Request MMIO/IOP resources
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Memory (MMIO), and I/O port addresses should NOT be read directly
+from the PCI device config space. Use the values in the pci_dev structure
+as the PCI "bus address" might have been remapped to a "host physical"
+address by the arch/chip-set specific kernel support.
+
+See Documentation/IO-mapping.txt for how to access device registers
+or device memory.
+
+The device driver needs to call pci_request_region() to verify
+no other device is already using the same address resource.
+Conversely, drivers should call pci_release_region() AFTER
+calling pci_disable_device().
+The idea is to prevent two devices colliding on the same address range.
+
+[ See OS BUG comment above. Currently (2.6.19), The driver can only
+ determine MMIO and IO Port resource availability _after_ calling
+ pci_enable_device(). ]
+
+Generic flavors of pci_request_region() are request_mem_region()
+(for MMIO ranges) and request_region() (for IO Port ranges).
+Use these for address resources that are not described by "normal" PCI
+BARs.
+
+Also see pci_request_selected_regions() below.
+
+
+3.3 Set the DMA mask size
+~~~~~~~~~~~~~~~~~~~~~~~~~
+[ If anything below doesn't make sense, please refer to
+ Documentation/DMA-API.txt. This section is just a reminder that
+ drivers need to indicate DMA capabilities of the device and is not
+ an authoritative source for DMA interfaces. ]
+
+While all drivers should explicitly indicate the DMA capability
+(e.g. 32 or 64 bit) of the PCI bus master, devices with more than
+32-bit bus master capability for streaming data need the driver
+to "register" this capability by calling pci_set_dma_mask() with
+appropriate parameters. In general this allows more efficient DMA
+on systems where System RAM exists above 4G _physical_ address.
+
+Drivers for all PCI-X and PCIe compliant devices must call
+pci_set_dma_mask() as they are 64-bit DMA devices.
+
+Similarly, drivers must also "register" this capability if the device
+can directly address "consistent memory" in System RAM above 4G physical
+address by calling pci_set_consistent_dma_mask().
+Again, this includes drivers for all PCI-X and PCIe compliant devices.
+Many 64-bit "PCI" devices (before PCI-X) and some PCI-X devices are
+64-bit DMA capable for payload ("streaming") data but not control
+("consistent") data.
+
+
+3.4 Setup shared control data
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Once the DMA masks are set, the driver can allocate "consistent" (a.k.a. shared)
+memory. See Documentation/DMA-API.txt for a full description of
+the DMA APIs. This section is just a reminder that it needs to be done
+before enabling DMA on the device.
+
+
+3.5 Initialize device registers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Some drivers will need specific "capability" fields programmed
+or other "vendor specific" register initialized or reset.
+E.g. clearing pending interrupts.
+
+
+3.6 Register IRQ handler
+~~~~~~~~~~~~~~~~~~~~~~~~
+While calling request_irq() is the last step described here,
+this is often just another intermediate step to initialize a device.
+This step can often be deferred until the device is opened for use.
+
+All interrupt handlers for IRQ lines should be registered with IRQF_SHARED
+and use the devid to map IRQs to devices (remember that all PCI IRQ lines
+can be shared).
+
+request_irq() will associate an interrupt handler and device handle
+with an interrupt number. Historically interrupt numbers represent
+IRQ lines which run from the PCI device to the Interrupt controller.
+With MSI and MSI-X (more below) the interrupt number is a CPU "vector".
+
+request_irq() also enables the interrupt. Make sure the device is
+quiesced and does not have any interrupts pending before registering
+the interrupt handler.
+
+MSI and MSI-X are PCI capabilities. Both are "Message Signaled Interrupts"
+which deliver interrupts to the CPU via a DMA write to a Local APIC.
+The fundamental difference between MSI and MSI-X is how multiple
+"vectors" get allocated. MSI requires contiguous blocks of vectors
+while MSI-X can allocate several individual ones.
+
+MSI capability can be enabled by calling pci_enable_msi() or
+pci_enable_msix() before calling request_irq(). This causes
+the PCI support to program CPU vector data into the PCI device
+capability registers.
+
+If your PCI device supports both, try to enable MSI-X first.
+Only one can be enabled at a time. Many architectures, chip-sets,
+or BIOSes do NOT support MSI or MSI-X and the call to pci_enable_msi/msix
+will fail. This is important to note since many drivers have
+two (or more) interrupt handlers: one for MSI/MSI-X and another for IRQs.
+They choose which handler to register with request_irq() based on the
+return value from pci_enable_msi/msix().
+
+There are (at least) two really good reasons for using MSI:
+1) MSI is an exclusive interrupt vector by definition.
+ This means the interrupt handler doesn't have to verify
+ its device caused the interrupt.
+
+2) MSI avoids DMA/IRQ race conditions. DMA to host memory is guaranteed
+ to be visible to the host CPU(s) when the MSI is delivered. This
+ is important for both data coherency and avoiding stale control data.
+ This guarantee allows the driver to omit MMIO reads to flush
+ the DMA stream.
+
+See drivers/infiniband/hw/mthca/ or drivers/net/tg3.c for examples
+of MSI/MSI-X usage.
+
+
+
+4. PCI device shutdown
+~~~~~~~~~~~~~~~~~~~~~~~
+
+When a PCI device driver is being unloaded, most of the following
+steps need to be performed:
+
+ Disable the device from generating IRQs
+ Release the IRQ (free_irq())
+ Stop all DMA activity
+ Release DMA buffers (both streaming and consistent)
+ Unregister from other subsystems (e.g. scsi or netdev)
+ Disable device from responding to MMIO/IO Port addresses
+ Release MMIO/IO Port resource(s)
+
+
+4.1 Stop IRQs on the device
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+How to do this is chip/device specific. If it's not done, it opens
+the possibility of a "screaming interrupt" if (and only if)
+the IRQ is shared with another device.
+
+When the shared IRQ handler is "unhooked", the remaining devices
+using the same IRQ line will still need the IRQ enabled. Thus if the
+"unhooked" device asserts IRQ line, the system will respond assuming
+it was one of the remaining devices asserted the IRQ line. Since none
+of the other devices will handle the IRQ, the system will "hang" until
+it decides the IRQ isn't going to get handled and masks the IRQ (100,000
+iterations later). Once the shared IRQ is masked, the remaining devices
+will stop functioning properly. Not a nice situation.
+
+This is another reason to use MSI or MSI-X if it's available.
+MSI and MSI-X are defined to be exclusive interrupts and thus
+are not susceptible to the "screaming interrupt" problem.
+
+
+4.2 Release the IRQ
+~~~~~~~~~~~~~~~~~~~
+Once the device is quiesced (no more IRQs), one can call free_irq().
+This function will return control once any pending IRQs are handled,
+"unhook" the drivers IRQ handler from that IRQ, and finally release
+the IRQ if no one else is using it.
+
+
+4.3 Stop all DMA activity
+~~~~~~~~~~~~~~~~~~~~~~~~~
+It's extremely important to stop all DMA operations BEFORE attempting
+to deallocate DMA control data. Failure to do so can result in memory
+corruption, hangs, and on some chip-sets a hard crash.
+
+Stopping DMA after stopping the IRQs can avoid races where the
+IRQ handler might restart DMA engines.
+
+While this step sounds obvious and trivial, several "mature" drivers
+didn't get this step right in the past.
+
+
+4.4 Release DMA buffers
+~~~~~~~~~~~~~~~~~~~~~~~
+Once DMA is stopped, clean up streaming DMA first.
+I.e. unmap data buffers and return buffers to "upstream"
+owners if there is one.
+
+Then clean up "consistent" buffers which contain the control data.
+
+See Documentation/DMA-API.txt for details on unmapping interfaces.
+
+
+4.5 Unregister from other subsystems
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Most low level PCI device drivers support some other subsystem
+like USB, ALSA, SCSI, NetDev, Infiniband, etc. Make sure your
+driver isn't losing resources from that other subsystem.
+If this happens, typically the symptom is an Oops (panic) when
+the subsystem attempts to call into a driver that has been unloaded.
+
+
+4.6 Disable Device from responding to MMIO/IO Port addresses
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+io_unmap() MMIO or IO Port resources and then call pci_disable_device().
+This is the symmetric opposite of pci_enable_device().
+Do not access device registers after calling pci_disable_device().
+
+
+4.7 Release MMIO/IO Port Resource(s)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Call pci_release_region() to mark the MMIO or IO Port range as available.
+Failure to do so usually results in the inability to reload the driver.
+
+
+
+5. How to access PCI config space
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can use pci_(read|write)_config_(byte|word|dword) to access the config
+space of a device represented by struct pci_dev *. All these functions return 0
+when successful or an error code (PCIBIOS_...) which can be translated to a text
+string by pcibios_strerror. Most drivers expect that accesses to valid PCI
+devices don't fail.
+
+If you don't have a struct pci_dev available, you can call
+pci_bus_(read|write)_config_(byte|word|dword) to access a given device
+and function on that bus.
+
+If you access fields in the standard portion of the config header, please
+use symbolic names of locations and bits declared in <linux/pci.h>.
+
+If you need to access Extended PCI Capability registers, just call
+pci_find_capability() for the particular capability and it will find the
+corresponding register block for you.
+
+
+
+6. Other interesting functions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+pci_find_slot() Find pci_dev corresponding to given bus and
+ slot numbers.
+pci_set_power_state() Set PCI Power Management state (0=D0 ... 3=D3)
+pci_find_capability() Find specified capability in device's capability
+ list.
+pci_resource_start() Returns bus start address for a given PCI region
+pci_resource_end() Returns bus end address for a given PCI region
+pci_resource_len() Returns the byte length of a PCI region
+pci_set_drvdata() Set private driver data pointer for a pci_dev
+pci_get_drvdata() Return private driver data pointer for a pci_dev
+pci_set_mwi() Enable Memory-Write-Invalidate transactions.
+pci_clear_mwi() Disable Memory-Write-Invalidate transactions.
+
+
+
+7. Miscellaneous hints
+~~~~~~~~~~~~~~~~~~~~~~
+
+When displaying PCI device names to the user (for example when a driver wants
+to tell the user what card has it found), please use pci_name(pci_dev).
+
+Always refer to the PCI devices by a pointer to the pci_dev structure.
+All PCI layer functions use this identification and it's the only
+reasonable one. Don't use bus/slot/function numbers except for very
+special purposes -- on systems with multiple primary buses their semantics
+can be pretty complex.
+
+Don't try to turn on Fast Back to Back writes in your driver. All devices
+on the bus need to be capable of doing it, so this is something which needs
+to be handled by platform and generic code, not individual drivers.
+
+
+
+8. Vendor and device identifications
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+One is not not required to add new device ids to include/linux/pci_ids.h.
+Please add PCI_VENDOR_ID_xxx for vendors and a hex constant for device ids.
+
+PCI_VENDOR_ID_xxx constants are re-used. The device ids are arbitrary
+hex numbers (vendor controlled) and normally used only in a single
+location, the pci_device_id table.
+
+Please DO submit new vendor/device ids to pciids.sourceforge.net project.
+
+
+
+9. Obsolete functions
+~~~~~~~~~~~~~~~~~~~~~
+
+There are several functions which you might come across when trying to
+port an old driver to the new PCI interface. They are no longer present
+in the kernel as they aren't compatible with hotplug or PCI domains or
+having sane locking.
+
+pci_find_device() Superseded by pci_get_device()
+pci_find_subsys() Superseded by pci_get_subsys()
+pci_find_slot() Superseded by pci_get_slot()
+
+
+The alternative is the traditional PCI device driver that walks PCI
+device lists. This is still possible but discouraged.
+
+
+
+10. MMIO Space and "Write Posting"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Converting a driver from using I/O Port space to using MMIO space
+often requires some additional changes. Specifically, "write posting"
+needs to be handled. Many drivers (e.g. tg3, acenic, sym53c8xx_2)
+already do this. I/O Port space guarantees write transactions reach the PCI
+device before the CPU can continue. Writes to MMIO space allow the CPU
+to continue before the transaction reaches the PCI device. HW weenies
+call this "Write Posting" because the write completion is "posted" to
+the CPU before the transaction has reached its destination.
+
+Thus, timing sensitive code should add readl() where the CPU is
+expected to wait before doing other work. The classic "bit banging"
+sequence works fine for I/O Port space:
+
+ for (i = 8; --i; val >>= 1) {
+ outb(val & 1, ioport_reg); /* write bit */
+ udelay(10);
+ }
+
+The same sequence for MMIO space should be:
+
+ for (i = 8; --i; val >>= 1) {
+ writeb(val & 1, mmio_reg); /* write bit */
+ readb(safe_mmio_reg); /* flush posted write */
+ udelay(10);
+ }
+
+It is important that "safe_mmio_reg" not have any side effects that
+interferes with the correct operation of the device.
+
+Another case to watch out for is when resetting a PCI device. Use PCI
+Configuration space reads to flush the writel(). This will gracefully
+handle the PCI master abort on all platforms if the PCI device is
+expected to not respond to a readl(). Most x86 platforms will allow
+MMIO reads to master abort (a.k.a. "Soft Fail") and return garbage
+(e.g. ~0). But many RISC platforms will crash (a.k.a."Hard Fail").

+ The PCI Express Advanced Error Reporting Driver Guide HOWTO
+ T. Long Nguyen <tom.l.nguyen@intel.com>
+ Yanmin Zhang <yanmin.zhang@intel.com>
+ 07/29/2006
+
+
+1. Overview
+
+1.1 About this guide
+
+This guide describes the basics of the PCI Express Advanced Error
+Reporting (AER) driver and provides information on how to use it, as
+well as how to enable the drivers of endpoint devices to conform with
+PCI Express AER driver.
+
+1.2 Copyright © Intel Corporation 2006.
+
+1.3 What is the PCI Express AER Driver?
+
+PCI Express error signaling can occur on the PCI Express link itself
+or on behalf of transactions initiated on the link. PCI Express
+defines two error reporting paradigms: the baseline capability and
+the Advanced Error Reporting capability. The baseline capability is
+required of all PCI Express components providing a minimum defined
+set of error reporting requirements. Advanced Error Reporting
+capability is implemented with a PCI Express advanced error reporting
+extended capability structure providing more robust error reporting.
+
+The PCI Express AER driver provides the infrastructure to support PCI
+Express Advanced Error Reporting capability. The PCI Express AER
+driver provides three basic functions:
+
+- Gathers the comprehensive error information if errors occurred.
+- Reports error to the users.
+- Performs error recovery actions.
+
+AER driver only attaches root ports which support PCI-Express AER
+capability.
+
+
+2. User Guide
+
+2.1 Include the PCI Express AER Root Driver into the Linux Kernel
+
+The PCI Express AER Root driver is a Root Port service driver attached
+to the PCI Express Port Bus driver. If a user wants to use it, the driver
+has to be compiled. Option CONFIG_PCIEAER supports this capability. It
+depends on CONFIG_PCIEPORTBUS, so pls. set CONFIG_PCIEPORTBUS=y and
+CONFIG_PCIEAER = y.
+
+2.2 Load PCI Express AER Root Driver
+There is a case where a system has AER support in BIOS. Enabling the AER
+Root driver and having AER support in BIOS may result unpredictable
+behavior. To avoid this conflict, a successful load of the AER Root driver
+requires ACPI _OSC support in the BIOS to allow the AER Root driver to
+request for native control of AER. See the PCI FW 3.0 Specification for
+details regarding OSC usage. Currently, lots of firmwares don't provide
+_OSC support while they use PCI Express. To support such firmwares,
+forceload, a parameter of type bool, could enable AER to continue to
+be initiated although firmwares have no _OSC support. To enable the
+walkaround, pls. add aerdriver.forceload=y to kernel boot parameter line
+when booting kernel. Note that forceload=n by default.
+
+2.3 AER error output
+When a PCI-E AER error is captured, an error message will be outputed to
+console. If it's a correctable error, it is outputed as a warning.
+Otherwise, it is printed as an error. So users could choose different
+log level to filter out correctable error messages.
+
+Below shows an example.
++------ PCI-Express Device Error -----+
+Error Severity : Uncorrected (Fatal)
+PCIE Bus Error type : Transaction Layer
+Unsupported Request : First
+Requester ID : 0500
+VendorID=8086h, DeviceID=0329h, Bus=05h, Device=00h, Function=00h
+TLB Header:
+04000001 00200a03 05010000 00050100
+
+In the example, 'Requester ID' means the ID of the device who sends
+the error message to root port. Pls. refer to pci express specs for
+other fields.
+
+
+3. Developer Guide
+
+To enable AER aware support requires a software driver to configure
+the AER capability structure within its device and to provide callbacks.
+
+To support AER better, developers need understand how AER does work
+firstly.
+
+PCI Express errors are classified into two types: correctable errors
+and uncorrectable errors. This classification is based on the impacts
+of those errors, which may result in degraded performance or function
+failure.
+
+Correctable errors pose no impacts on the functionality of the
+interface. The PCI Express protocol can recover without any software
+intervention or any loss of data. These errors are detected and
+corrected by hardware. Unlike correctable errors, uncorrectable
+errors impact functionality of the interface. Uncorrectable errors
+can cause a particular transaction or a particular PCI Express link
+to be unreliable. Depending on those error conditions, uncorrectable
+errors are further classified into non-fatal errors and fatal errors.
+Non-fatal errors cause the particular transaction to be unreliable,
+but the PCI Express link itself is fully functional. Fatal errors, on
+the other hand, cause the link to be unreliable.
+
+When AER is enabled, a PCI Express device will automatically send an
+error message to the PCIE root port above it when the device captures
+an error. The Root Port, upon receiving an error reporting message,
+internally processes and logs the error message in its PCI Express
+capability structure. Error information being logged includes storing
+the error reporting agent's requestor ID into the Error Source
+Identification Registers and setting the error bits of the Root Error
+Status Register accordingly. If AER error reporting is enabled in Root
+Error Command Register, the Root Port generates an interrupt if an
+error is detected.
+
+Note that the errors as described above are related to the PCI Express
+hierarchy and links. These errors do not include any device specific
+errors because device specific errors will still get sent directly to
+the device driver.
+
+3.1 Configure the AER capability structure
+
+AER aware drivers of PCI Express component need change the device
+control registers to enable AER. They also could change AER registers,
+including mask and severity registers. Helper function
+pci_enable_pcie_error_reporting could be used to enable AER. See
+section 3.3.
+
+3.2. Provide callbacks
+
+3.2.1 callback reset_link to reset pci express link
+
+This callback is used to reset the pci express physical link when a
+fatal error happens. The root port aer service driver provides a
+default reset_link function, but different upstream ports might
+have different specifications to reset pci express link, so all
+upstream ports should provide their own reset_link functions.
+
+In struct pcie_port_service_driver, a new pointer, reset_link, is
+added.
+
+pci_ers_result_t (*reset_link) (struct pci_dev *dev);
+
+Section 3.2.2.2 provides more detailed info on when to call
+reset_link.
+
+3.2.2 PCI error-recovery callbacks
+
+The PCI Express AER Root driver uses error callbacks to coordinate
+with downstream device drivers associated with a hierarchy in question
+when performing error recovery actions.
+
+Data struct pci_driver has a pointer, err_handler, to point to
+pci_error_handlers who consists of a couple of callback function
+pointers. AER driver follows the rules defined in
+pci-error-recovery.txt except pci express specific parts (e.g.
+reset_link). Pls. refer to pci-error-recovery.txt for detailed
+definitions of the callbacks.
+
+Below sections specify when to call the error callback functions.
+
+3.2.2.1 Correctable errors
+
+Correctable errors pose no impacts on the functionality of
+the interface. The PCI Express protocol can recover without any
+software intervention or any loss of data. These errors do not
+require any recovery actions. The AER driver clears the device's
+correctable error status register accordingly and logs these errors.
+
+3.2.2.2 Non-correctable (non-fatal and fatal) errors
+
+If an error message indicates a non-fatal error, performing link reset
+at upstream is not required. The AER driver calls error_detected(dev,
+pci_channel_io_normal) to all drivers associated within a hierarchy in
+question. for example,
+EndPoint<==>DownstreamPort B<==>UpstreamPort A<==>RootPort.
+If Upstream port A captures an AER error, the hierarchy consists of
+Downstream port B and EndPoint.
+
+A driver may return PCI_ERS_RESULT_CAN_RECOVER,
+PCI_ERS_RESULT_DISCONNECT, or PCI_ERS_RESULT_NEED_RESET, depending on
+whether it can recover or the AER driver calls mmio_enabled as next.
+
+If an error message indicates a fatal error, kernel will broadcast
+error_detected(dev, pci_channel_io_frozen) to all drivers within
+a hierarchy in question. Then, performing link reset at upstream is
+necessary. As different kinds of devices might use different approaches
+to reset link, AER port service driver is required to provide the
+function to reset link. Firstly, kernel looks for if the upstream
+component has an aer driver. If it has, kernel uses the reset_link
+callback of the aer driver. If the upstream component has no aer driver
+and the port is downstream port, we will use the aer driver of the
+root port who reports the AER error. As for upstream ports,
+they should provide their own aer service drivers with reset_link
+function. If error_detected returns PCI_ERS_RESULT_CAN_RECOVER and
+reset_link returns PCI_ERS_RESULT_RECOVERED, the error handling goes
+to mmio_enabled.
+
+3.3 helper functions
+
+3.3.1 int pci_find_aer_capability(struct pci_dev *dev);
+pci_find_aer_capability locates the PCI Express AER capability
+in the device configuration space. If the device doesn't support
+PCI-Express AER, the function returns 0.
+
+3.3.2 int pci_enable_pcie_error_reporting(struct pci_dev *dev);
+pci_enable_pcie_error_reporting enables the device to send error
+messages to root port when an error is detected. Note that devices
+don't enable the error reporting by default, so device drivers need
+call this function to enable it.
+
+3.3.3 int pci_disable_pcie_error_reporting(struct pci_dev *dev);
+pci_disable_pcie_error_reporting disables the device to send error
+messages to root port when an error is detected.
+
+3.3.4 int pci_cleanup_aer_uncorrect_error_status(struct pci_dev *dev);
+pci_cleanup_aer_uncorrect_error_status cleanups the uncorrectable
+error status register.
+
+3.4 Frequent Asked Questions
+
+Q: What happens if a PCI Express device driver does not provide an
+error recovery handler (pci_driver->err_handler is equal to NULL)?
+
+A: The devices attached with the driver won't be recovered. If the
+error is fatal, kernel will print out warning messages. Please refer
+to section 3 for more information.
+
+Q: What happens if an upstream port service driver does not provide
+callback reset_link?
+
+A: Fatal error recovery will fail if the errors are reported by the
+upstream ports who are attached by the service driver.
+
+Q: How does this infrastructure deal with driver that is not PCI
+Express aware?
+
+A: This infrastructure calls the error callback functions of the
+driver when an error happens. But if the driver is not aware of
+PCI Express, the device might not report its own errors to root
+port.
+
+Q: What modifications will that driver need to make it compatible
+with the PCI Express AER Root driver?
+
+A: It could call the helper functions to enable AER in devices and
+cleanup uncorrectable status register. Pls. refer to section 3.3.

- The PCI Express Port Bus Driver Guide HOWTO
- Tom L Nguyen tom.l.nguyen@intel.com
- 11/03/2004
-
-1. About this guide
-
-This guide describes the basics of the PCI Express Port Bus driver
-and provides information on how to enable the service drivers to
-register/unregister with the PCI Express Port Bus Driver.
-
-2. Copyright 2004 Intel Corporation
-
-3. What is the PCI Express Port Bus Driver
-
-A PCI Express Port is a logical PCI-PCI Bridge structure. There
-are two types of PCI Express Port: the Root Port and the Switch
-Port. The Root Port originates a PCI Express link from a PCI Express
-Root Complex and the Switch Port connects PCI Express links to
-internal logical PCI buses. The Switch Port, which has its secondary
-bus representing the switch's internal routing logic, is called the
-switch's Upstream Port. The switch's Downstream Port is bridging from
-switch's internal routing bus to a bus representing the downstream
-PCI Express link from the PCI Express Switch.
-
-A PCI Express Port can provide up to four distinct functions,
-referred to in this document as services, depending on its port type.
-PCI Express Port's services include native hotplug support (HP),
-power management event support (PME), advanced error reporting
-support (AER), and virtual channel support (VC). These services may
-be handled by a single complex driver or be individually distributed
-and handled by corresponding service drivers.
-
-4. Why use the PCI Express Port Bus Driver?
-
-In existing Linux kernels, the Linux Device Driver Model allows a
-physical device to be handled by only a single driver. The PCI
-Express Port is a PCI-PCI Bridge device with multiple distinct
-services. To maintain a clean and simple solution each service
-may have its own software service driver. In this case several
-service drivers will compete for a single PCI-PCI Bridge device.
-For example, if the PCI Express Root Port native hotplug service
-driver is loaded first, it claims a PCI-PCI Bridge Root Port. The
-kernel therefore does not load other service drivers for that Root
-Port. In other words, it is impossible to have multiple service
-drivers load and run on a PCI-PCI Bridge device simultaneously
-using the current driver model.
-
-To enable multiple service drivers running simultaneously requires
-having a PCI Express Port Bus driver, which manages all populated
-PCI Express Ports and distributes all provided service requests
-to the corresponding service drivers as required. Some key
-advantages of using the PCI Express Port Bus driver are listed below:
-
- - Allow multiple service drivers to run simultaneously on
- a PCI-PCI Bridge Port device.
-
- - Allow service drivers implemented in an independent
- staged approach.
-
- - Allow one service driver to run on multiple PCI-PCI Bridge
- Port devices.
-
- - Manage and distribute resources of a PCI-PCI Bridge Port
- device to requested service drivers.
-
-5. Configuring the PCI Express Port Bus Driver vs. Service Drivers
-
-5.1 Including the PCI Express Port Bus Driver Support into the Kernel
-
-Including the PCI Express Port Bus driver depends on whether the PCI
-Express support is included in the kernel config. The kernel will
-automatically include the PCI Express Port Bus driver as a kernel
-driver when the PCI Express support is enabled in the kernel.
-
-5.2 Enabling Service Driver Support
-
-PCI device drivers are implemented based on Linux Device Driver Model.
-All service drivers are PCI device drivers. As discussed above, it is
-impossible to load any service driver once the kernel has loaded the
-PCI Express Port Bus Driver. To meet the PCI Express Port Bus Driver
-Model requires some minimal changes on existing service drivers that
-imposes no impact on the functionality of existing service drivers.
-
-A service driver is required to use the two APIs shown below to
-register its service with the PCI Express Port Bus driver (see
-section 5.2.1 & 5.2.2). It is important that a service driver
-initializes the pcie_port_service_driver data structure, included in
-header file /include/linux/pcieport_if.h, before calling these APIs.
-Failure to do so will result an identity mismatch, which prevents
-the PCI Express Port Bus driver from loading a service driver.
-
-5.2.1 pcie_port_service_register
-
-int pcie_port_service_register(struct pcie_port_service_driver *new)
-
-This API replaces the Linux Driver Model's pci_module_init API. A
-service driver should always calls pcie_port_service_register at
-module init. Note that after service driver being loaded, calls
-such as pci_enable_device(dev) and pci_set_master(dev) are no longer
-necessary since these calls are executed by the PCI Port Bus driver.
-
-5.2.2 pcie_port_service_unregister
-
-void pcie_port_service_unregister(struct pcie_port_service_driver *new)
-
-pcie_port_service_unregister replaces the Linux Driver Model's
-pci_unregister_driver. It's always called by service driver when a
-module exits.
-
-5.2.3 Sample Code
-
-Below is sample service driver code to initialize the port service
-driver data structure.
-
-static struct pcie_port_service_id service_id[] = { {
- .vendor = PCI_ANY_ID,
- .device = PCI_ANY_ID,
- .port_type = PCIE_RC_PORT,
- .service_type = PCIE_PORT_SERVICE_AER,
- }, { /* end: all zeroes */ }
-};
-
-static struct pcie_port_service_driver root_aerdrv = {
- .name = (char *)device_name,
- .id_table = &service_id[0],
-
- .probe = aerdrv_load,
- .remove = aerdrv_unload,
-
- .suspend = aerdrv_suspend,
- .resume = aerdrv_resume,
-};
-
-Below is a sample code for registering/unregistering a service
-driver.
-
-static int __init aerdrv_service_init(void)
-{
- int retval = 0;
-
- retval = pcie_port_service_register(&root_aerdrv);
- if (!retval) {
- /*
- * FIX ME
- */
- }
- return retval;
-}
-
-static void __exit aerdrv_service_exit(void)
-{
- pcie_port_service_unregister(&root_aerdrv);
-}
-
-module_init(aerdrv_service_init);
-module_exit(aerdrv_service_exit);
-
-6. Possible Resource Conflicts
-
-Since all service drivers of a PCI-PCI Bridge Port device are
-allowed to run simultaneously, below lists a few of possible resource
-conflicts with proposed solutions.
-
-6.1 MSI Vector Resource
-
-The MSI capability structure enables a device software driver to call
-pci_enable_msi to request MSI based interrupts. Once MSI interrupts
-are enabled on a device, it stays in this mode until a device driver
-calls pci_disable_msi to disable MSI interrupts and revert back to
-INTx emulation mode. Since service drivers of the same PCI-PCI Bridge
-port share the same physical device, if an individual service driver
-calls pci_enable_msi/pci_disable_msi it may result unpredictable
-behavior. For example, two service drivers run simultaneously on the
-same physical Root Port. Both service drivers call pci_enable_msi to
-request MSI based interrupts. A service driver may not know whether
-any other service drivers have run on this Root Port. If either one
-of them calls pci_disable_msi, it puts the other service driver
-in a wrong interrupt mode.
-
-To avoid this situation all service drivers are not permitted to
-switch interrupt mode on its device. The PCI Express Port Bus driver
-is responsible for determining the interrupt mode and this should be
-transparent to service drivers. Service drivers need to know only
-the vector IRQ assigned to the field irq of struct pcie_device, which
-is passed in when the PCI Express Port Bus driver probes each service
-driver. Service drivers should use (struct pcie_device*)dev->irq to
-call request_irq/free_irq. In addition, the interrupt mode is stored
-in the field interrupt_mode of struct pcie_device.
-
-6.2 MSI-X Vector Resources
-
-Similar to the MSI a device driver for an MSI-X capable device can
-call pci_enable_msix to request MSI-X interrupts. All service drivers
-are not permitted to switch interrupt mode on its device. The PCI
-Express Port Bus driver is responsible for determining the interrupt
-mode and this should be transparent to service drivers. Any attempt
-by service driver to call pci_enable_msix/pci_disable_msix may
-result unpredictable behavior. Service drivers should use
-(struct pcie_device*)dev->irq and call request_irq/free_irq.
-
-6.3 PCI Memory/IO Mapped Regions
-
-Service drivers for PCI Express Power Management (PME), Advanced
-Error Reporting (AER), Hot-Plug (HP) and Virtual Channel (VC) access
-PCI configuration space on the PCI Express port. In all cases the
-registers accessed are independent of each other. This patch assumes
-that all service drivers will be well behaved and not overwrite
-other service driver's configuration settings.
-
-6.4 PCI Config Registers
-
-Each service driver runs its PCI config operations on its own
-capability structure except the PCI Express capability structure, in
-which Root Control register and Device Control register are shared
-between PME and AER. This patch assumes that all service drivers
-will be well behaved and not overwrite other service driver's
-configuration settings.

+ S3C24XX NAND Support
+ ====================
+
+Introduction
+------------
+
+Small Page NAND
+---------------
+
+The driver uses a 512 byte (1 page) ECC code for this setup. The
+ECC code is not directly compatible with the default kernel ECC
+code, so the driver enforces its own OOB layout and ECC parameters
+
+Large Page NAND
+---------------
+
+The driver is capable of handling NAND flash with a 2KiB page
+size, with support for hardware ECC generation and correction.
+
+Unlike the 512byte page mode, the driver generates ECC data for
+each 256 byte block in an 2KiB page. This means that more than
+one error in a page can be rectified. It also means that the
+OOB layout remains the default kernel layout for these flashes.

+
+1.8 What is sched_relax_domain_level ?
+--------------------------------------
+
+In sched domain, the scheduler migrates tasks in 2 ways; periodic load
+balance on tick, and at time of some schedule events.
+
+When a task is woken up, scheduler try to move the task on idle CPU.
+For example, if a task A running on CPU X activates another task B
+on the same CPU X, and if CPU Y is X's sibling and performing idle,
+then scheduler migrate task B to CPU Y so that task B can start on
+CPU Y without waiting task A on CPU X.
+
+And if a CPU run out of tasks in its runqueue, the CPU try to pull
+extra tasks from other busy CPUs to help them before it is going to
+be idle.
+
+Of course it takes some searching cost to find movable tasks and/or
+idle CPUs, the scheduler might not search all CPUs in the domain
+everytime. In fact, in some architectures, the searching ranges on
+events are limited in the same socket or node where the CPU locates,
+while the load balance on tick searchs all.
+
+For example, assume CPU Z is relatively far from CPU X. Even if CPU Z
+is idle while CPU X and the siblings are busy, scheduler can't migrate
+woken task B from X to Z since it is out of its searching range.
+As the result, task B on CPU X need to wait task A or wait load balance
+on the next tick. For some applications in special situation, waiting
+1 tick may be too long.
+
+The 'sched_relax_domain_level' file allows you to request changing
+this searching range as you like. This file takes int value which
+indicates size of searching range in levels ideally as follows,
+otherwise initial value -1 that indicates the cpuset has no request.
+
+ -1 : no request. use system default or follow request of others.
+ 0 : no search.
+ 1 : search siblings (hyperthreads in a core).
+ 2 : search cores in a package.
+ 3 : search cpus in a node [= system wide on non-NUMA system]
+ ( 4 : search nodes in a chunk of node [on NUMA system] )
+ ( 5~ : search system wide [on NUMA system])
+
+This file is per-cpuset and affect the sched domain where the cpuset
+belongs to. Therefore if the flag 'sched_load_balance' of a cpuset
+is disabled, then 'sched_relax_domain_level' have no effect since
+there is no sched domain belonging the cpuset.
+
+If multiple cpusets are overlapping and hence they form a single sched
+domain, the largest value among those is used. Be careful, if one
+requests 0 and others are -1 then 0 is used.
+
+Note that modifying this file will have both good and bad effects,
+and whether it is acceptable or not will be depend on your situation.
+Don't modify this file if you are not sure.
+
+If your situation is:
+ - The migration costs between each cpu can be assumed considerably
+ small(for you) due to your special application's behavior or
+ special hardware support for CPU cache etc.
+ - The searching cost doesn't have impact(for you) or you can make
+ the searching cost enough small by managing cpuset to compact etc.
+ - The latency is required even it sacrifices cache hit rate etc.
+then increasing 'sched_relax_domain_level' would benefit you.

+dm-crypt
+=========
+
+Device-Mapper's "crypt" target provides transparent encryption of block devices
+using the kernel crypto API.
+
+Parameters: <cipher> <key> <iv_offset> <device path> <offset>
+
+<cipher>
+ Encryption cipher and an optional IV generation mode.
+ (In format cipher-chainmode-ivopts:ivmode).
+ Examples:
+ des
+ aes-cbc-essiv:sha256
+ twofish-ecb
+
+ /proc/crypto contains supported crypto modes
+
+<key>
+ Key used for encryption. It is encoded as a hexadecimal number.
+ You can only use key sizes that are valid for the selected cipher.
+
+<iv_offset>
+ The IV offset is a sector count that is added to the sector number
+ before creating the IV.
+
+<device path>
+ This is the device that is going to be used as backend and contains the
+ encrypted data. You can specify it as a path like /dev/xxx or a device
+ number <major>:<minor>.
+
+<offset>
+ Starting sector within the device where the encrypted data begins.
+
+Example scripts
+===============
+LUKS (Linux Unified Key Setup) is now the preferred way to set up disk
+encryption with dm-crypt using the 'cryptsetup' utility, see
+http://luks.endorphin.org/
+
+[[
+#!/bin/sh
+# Create a crypt device using dmsetup
+dmsetup create crypt1 --table "0 `blockdev --getsize $1` crypt aes-cbc-essiv:sha256 babebabebabebabebabebabebabebabe 0 $1 0"

+ - NFS/RDMA Setup
+
+Overview
+~~~~~~~~
+
+ This document describes how to install and setup the Linux NFS/RDMA client
+ and server software.
+
+ The NFS/RDMA client was first included in Linux 2.6.24. The NFS/RDMA server
+ was first included in the following release, Linux 2.6.25.
+
+ In our testing, we have obtained excellent performance results (full 10Gbit
+ wire bandwidth at minimal client CPU) under many workloads. The code passes
+ the full Connectathon test suite and operates over both Infiniband and iWARP
+ RDMA adapters.
+
+Getting Help
+~~~~~~~~~~~~
+
+ If you get stuck, you can ask questions on the
+
+ nfs-rdma-devel@lists.sourceforge.net
+
+ mailing list.
+
+Installation
+~~~~~~~~~~~~
+
+ These instructions are a step by step guide to building a machine for
+ use with NFS/RDMA.
+
+ - Install an RDMA device
+
+ Any device supported by the drivers in drivers/infiniband/hw is acceptable.
+
+ Testing has been performed using several Mellanox-based IB cards, the
+ Ammasso AMS1100 iWARP adapter, and the Chelsio cxgb3 iWARP adapter.
+
+ - Install a Linux distribution and tools
+
+ The first kernel release to contain both the NFS/RDMA client and server was
+ Linux 2.6.25 Therefore, a distribution compatible with this and subsequent
+ Linux kernel release should be installed.
+
+ The procedures described in this document have been tested with
+ distributions from Red Hat's Fedora Project (http://fedora.redhat.com/).
+
+ - Install nfs-utils-1.1.1 or greater on the client
+
+ An NFS/RDMA mount point can only be obtained by using the mount.nfs
+ command in nfs-utils-1.1.1 or greater. To see which version of mount.nfs
+ you are using, type:
+
+ > /sbin/mount.nfs -V
+
+ If the version is less than 1.1.1 or the command does not exist,
+ then you will need to install the latest version of nfs-utils.
+
+ Download the latest package from:
+
+ http://www.kernel.org/pub/linux/utils/nfs
+
+ Uncompress the package and follow the installation instructions.
+
+ If you will not be using GSS and NFSv4, the installation process
+ can be simplified by disabling these features when running configure:
+
+ > ./configure --disable-gss --disable-nfsv4
+
+ For more information on this see the package's README and INSTALL files.
+
+ After building the nfs-utils package, there will be a mount.nfs binary in
+ the utils/mount directory. This binary can be used to initiate NFS v2, v3,
+ or v4 mounts. To initiate a v4 mount, the binary must be called mount.nfs4.
+ The standard technique is to create a symlink called mount.nfs4 to mount.nfs.
+
+ NOTE: mount.nfs and therefore nfs-utils-1.1.1 or greater is only needed
+ on the NFS client machine. You do not need this specific version of
+ nfs-utils on the server. Furthermore, only the mount.nfs command from
+ nfs-utils-1.1.1 is needed on the client.
+
+ - Install a Linux kernel with NFS/RDMA
+
+ The NFS/RDMA client and server are both included in the mainline Linux
+ kernel version 2.6.25 and later. This and other versions of the 2.6 Linux
+ kernel can be found at:
+
+ ftp://ftp.kernel.org/pub/linux/kernel/v2.6/
+
+ Download the sources and place them in an appropriate location.
+
+ - Configure the RDMA stack
+
+ Make sure your kernel configuration has RDMA support enabled. Under
+ Device Drivers -> InfiniBand support, update the kernel configuration
+ to enable InfiniBand support [NOTE: the option name is misleading. Enabling
+ InfiniBand support is required for all RDMA devices (IB, iWARP, etc.)].
+
+ Enable the appropriate IB HCA support (mlx4, mthca, ehca, ipath, etc.) or
+ iWARP adapter support (amso, cxgb3, etc.).
+
+ If you are using InfiniBand, be sure to enable IP-over-InfiniBand support.
+
+ - Configure the NFS client and server
+
+ Your kernel configuration must also have NFS file system support and/or
+ NFS server support enabled. These and other NFS related configuration
+ options can be found under File Systems -> Network File Systems.
+
+ - Build, install, reboot
+
+ The NFS/RDMA code will be enabled automatically if NFS and RDMA
+ are turned on. The NFS/RDMA client and server are configured via the hidden
+ SUNRPC_XPRT_RDMA config option that depends on SUNRPC and INFINIBAND. The
+ value of SUNRPC_XPRT_RDMA will be:
+
+ - N if either SUNRPC or INFINIBAND are N, in this case the NFS/RDMA client
+ and server will not be built
+ - M if both SUNRPC and INFINIBAND are on (M or Y) and at least one is M,
+ in this case the NFS/RDMA client and server will be built as modules
+ - Y if both SUNRPC and INFINIBAND are Y, in this case the NFS/RDMA client
+ and server will be built into the kernel
+
+ Therefore, if you have followed the steps above and turned no NFS and RDMA,
+ the NFS/RDMA client and server will be built.
+
+ Build a new kernel, install it, boot it.
+
+Check RDMA and NFS Setup
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+ Before configuring the NFS/RDMA software, it is a good idea to test
+ your new kernel to ensure that the kernel is working correctly.
+ In particular, it is a good idea to verify that the RDMA stack
+ is functioning as expected and standard NFS over TCP/IP and/or UDP/IP
+ is working properly.
+
+ - Check RDMA Setup
+
+ If you built the RDMA components as modules, load them at
+ this time. For example, if you are using a Mellanox Tavor/Sinai/Arbel
+ card:
+
+ > modprobe ib_mthca
+ > modprobe ib_ipoib
+
+ If you are using InfiniBand, make sure there is a Subnet Manager (SM)
+ running on the network. If your IB switch has an embedded SM, you can
+ use it. Otherwise, you will need to run an SM, such as OpenSM, on one
+ of your end nodes.
+
+ If an SM is running on your network, you should see the following:
+
+ > cat /sys/class/infiniband/driverX/ports/1/state
+ 4: ACTIVE
+
+ where driverX is mthca0, ipath5, ehca3, etc.
+
+ To further test the InfiniBand software stack, use IPoIB (this
+ assumes you have two IB hosts named host1 and host2):
+
+ host1> ifconfig ib0 a.b.c.x
+ host2> ifconfig ib0 a.b.c.y
+ host1> ping a.b.c.y
+ host2> ping a.b.c.x
+
+ For other device types, follow the appropriate procedures.
+
+ - Check NFS Setup
+
+ For the NFS components enabled above (client and/or server),
+ test their functionality over standard Ethernet using TCP/IP or UDP/IP.
+
+NFS/RDMA Setup
+~~~~~~~~~~~~~~
+
+ We recommend that you use two machines, one to act as the client and
+ one to act as the server.
+
+ One time configuration:
+
+ - On the server system, configure the /etc/exports file and
+ start the NFS/RDMA server.
+
+ Exports entries with the following formats have been tested:
+
+ /vol0 192.168.0.47(fsid=0,rw,async,insecure,no_root_squash)
+ /vol0 192.168.0.0/255.255.255.0(fsid=0,rw,async,insecure,no_root_squash)
+
+ The IP address(es) is(are) the client's IPoIB address for an InfiniBand HCA or the
+ cleint's iWARP address(es) for an RNIC.
+
+ NOTE: The "insecure" option must be used because the NFS/RDMA client does not
+ use a reserved port.
+
+ Each time a machine boots:
+
+ - Load and configure the RDMA drivers
+
+ For InfiniBand using a Mellanox adapter:
+
+ > modprobe ib_mthca
+ > modprobe ib_ipoib
+ > ifconfig ib0 a.b.c.d
+
+ NOTE: use unique addresses for the client and server
+
+ - Start the NFS server
+
+ If the NFS/RDMA server was built as a module (CONFIG_SUNRPC_XPRT_RDMA=m in kernel config),
+ load the RDMA transport module:
+
+ > modprobe svcrdma
+
+ Regardless of how the server was built (module or built-in), start the server:
+
+ > /etc/init.d/nfs start
+
+ or
+
+ > service nfs start
+
+ Instruct the server to listen on the RDMA transport:
+
+ > echo rdma 2050 > /proc/fs/nfsd/portlist
+
+ - On the client system
+
+ If the NFS/RDMA client was built as a module (CONFIG_SUNRPC_XPRT_RDMA=m in kernel config),
+ load the RDMA client module:
+
+ > modprobe xprtrdma.ko
+
+ Regardless of how the client was built (module or built-in), issue the mount.nfs command:
+
+ > /path/to/your/mount.nfs <IPoIB-server-name-or-address>:/<export> /mnt -i -o rdma,port=2050
+
+ To verify that the mount is using RDMA, run "cat /proc/mounts" and check the
+ "proto" field for the given mount.
+
+ Congratulations! You're using NFS/RDMA!

+Currently, kvm module in EXPERIMENTAL stage on IA64. This means that
+interfaces are not stable enough to use. So, plase had better don't run
+critical applications in virtual machine. We will try our best to make it
+strong in future versions!
+ Guide: How to boot up guests on kvm/ia64
+
+This guide is to describe how to enable kvm support for IA-64 systems.
+
+1. Get the kvm source from git.kernel.org.
+ Userspace source:
+ git clone git://git.kernel.org/pub/scm/virt/kvm/kvm-userspace.git
+ Kernel Source:
+ git clone git://git.kernel.org/pub/scm/linux/kernel/git/xiantao/kvm-ia64.git
+
+2. Compile the source code.
+ 2.1 Compile userspace code:
+ (1)cd ./kvm-userspace
+ (2)./configure
+ (3)cd kernel
+ (4)make sync LINUX= $kernel_dir (kernel_dir is the directory of kernel source.)
+ (5)cd ..
+ (6)make qemu
+ (7)cd qemu; make install
+
+ 2.2 Compile kernel source code:
+ (1) cd ./$kernel_dir
+ (2) Make menuconfig
+ (3) Enter into virtualization option, and choose kvm.
+ (4) make
+ (5) Once (4) done, make modules_install
+ (6) Make initrd, and use new kernel to reboot up host machine.
+ (7) Once (6) done, cd $kernel_dir/arch/ia64/kvm
+ (8) insmod kvm.ko; insmod kvm-intel.ko
+
+Note: For step 2, please make sure that host page size == TARGET_PAGE_SIZE of qemu, otherwise, may fail.
+
+3. Get Guest Firmware named as Flash.fd, and put it under right place:
+ (1) If you have the guest firmware (binary) released by Intel Corp for Xen, use it directly.
+
+ (2) If you have no firmware at hand, Please download its source from
+ hg clone http://xenbits.xensource.com/ext/efi-vfirmware.hg
+ you can get the firmware's binary in the directory of efi-vfirmware.hg/binaries.
+
+ (3) Rename the firware you owned to Flash.fd, and copy it to /usr/local/share/qemu
+
+4. Boot up Linux or Windows guests:
+ 4.1 Create or install a image for guest boot. If you have xen experience, it should be easy.
+
+ 4.2 Boot up guests use the following command.
+ /usr/local/bin/qemu-system-ia64 -smp xx -m 512 -hda $your_image
+ (xx is the number of virtual processors for the guest, now the maximum value is 4)
+
+5. Known possibile issue on some platforms with old Firmware.
+
+If meet strange host crashe issues, try to solve it through either of the following ways:
+
+(1): Upgrade your Firmware to the latest one.
+
+(2): Applying the below patch to kernel source.

- * ht1 major 37, minor 1 second IDE tape, rewind on close.

- * General ide driver configuration options, such as the interrupt-unmask
- * flag, can be configured by issuing an ioctl to the block device interface,
- * as any other ide device.
- *
- * Our own ide-tape ioctl's can be issued to either the block device or
- * the character device interface.
- *
- * Maximal throughput with minimal bus load will usually be achieved in the
- * following scenario:
- *
- * 1. ide-tape is operating in the pipelined operation mode.
- * 2. No buffering is performed by the user backup program.
- *
- * Testing was done with a 2 GB CONNER CTMA 4000 IDE ATAPI Streaming Tape Drive.
- *
- * Here are some words from the first releases of hd.c, which are quoted
- * in ide.c and apply here as well:
- *
- * | Special care is recommended. Have Fun!
- *
- *
- * An overview of the pipelined operation mode.
- *
- * In the pipelined write mode, we will usually just add requests to our
- * pipeline and return immediately, before we even start to service them. The
- * user program will then have enough time to prepare the next request while
- * we are still busy servicing previous requests. In the pipelined read mode,
- * the situation is similar - we add read-ahead requests into the pipeline,
- * before the user even requested them.
- *
- * The pipeline can be viewed as a "safety net" which will be activated when
- * the system load is high and prevents the user backup program from keeping up
- * with the current tape speed. At this point, the pipeline will get
- * shorter and shorter but the tape will still be streaming at the same speed.
- * Assuming we have enough pipeline stages, the system load will hopefully
- * decrease before the pipeline is completely empty, and the backup program
- * will be able to "catch up" and refill the pipeline again.
- *
- * When using the pipelined mode, it would be best to disable any type of
- * buffering done by the user program, as ide-tape already provides all the
- * benefits in the kernel, where it can be done in a more efficient way.
- * As we will usually not block the user program on a request, the most
- * efficient user code will then be a simple read-write-read-... cycle.
- * Any additional logic will usually just slow down the backup process.
- *
- * Using the pipelined mode, I get a constant over 400 KBps throughput,
- * which seems to be the maximum throughput supported by my tape.
- *
- * However, there are some downfalls:
- *
- * 1. We use memory (for data buffers) in proportional to the number
- * of pipeline stages (each stage is about 26 KB with my tape).
- * 2. In the pipelined write mode, we cheat and postpone error codes
- * to the user task. In read mode, the actual tape position
- * will be a bit further than the last requested block.
- *
- * Concerning (1):
- *
- * 1. We allocate stages dynamically only when we need them. When
- * we don't need them, we don't consume additional memory. In
- * case we can't allocate stages, we just manage without them
- * (at the expense of decreased throughput) so when Linux is
- * tight in memory, we will not pose additional difficulties.
- *
- * 2. The maximum number of stages (which is, in fact, the maximum
- * amount of memory) which we allocate is limited by the compile
- * time parameter IDETAPE_MAX_PIPELINE_STAGES.
- *
- * 3. The maximum number of stages is a controlled parameter - We
- * don't start from the user defined maximum number of stages
- * but from the lower IDETAPE_MIN_PIPELINE_STAGES (again, we
- * will not even allocate this amount of stages if the user
- * program can't handle the speed). We then implement a feedback
- * loop which checks if the pipeline is empty, and if it is, we
- * increase the maximum number of stages as necessary until we
- * reach the optimum value which just manages to keep the tape
- * busy with minimum allocated memory or until we reach
- * IDETAPE_MAX_PIPELINE_STAGES.
- *
- * Concerning (2):
- *
- * In pipelined write mode, ide-tape can not return accurate error codes
- * to the user program since we usually just add the request to the
- * pipeline without waiting for it to be serviced. In case an error
- * occurs, I will report it on the next user request.
- *
- * In the pipelined read mode, subsequent read requests or forward
- * filemark spacing will perform correctly, as we preserve all blocks
- * and filemarks which we encountered during our excess read-ahead.
- *
- * For accurate tape positioning and error reporting, disabling
- * pipelined mode might be the best option.
- *
- * You can enable/disable/tune the pipelined operation mode by adjusting
- * the compile time parameters below.
- *

- How To Write Linux PCI Drivers
-
- by Martin Mares <mj@ucw.cz> on 07-Feb-2000
- updated by Grant Grundler <grundler@parisc-linux.org> on 23-Dec-2006
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-The world of PCI is vast and full of (mostly unpleasant) surprises.
-Since each CPU architecture implements different chip-sets and PCI devices
-have different requirements (erm, "features"), the result is the PCI support
-in the Linux kernel is not as trivial as one would wish. This short paper
-tries to introduce all potential driver authors to Linux APIs for
-PCI device drivers.
-
-A more complete resource is the third edition of "Linux Device Drivers"
-by Jonathan Corbet, Alessandro Rubini, and Greg Kroah-Hartman.
-LDD3 is available for free (under Creative Commons License) from:
-
- http://lwn.net/Kernel/LDD3/
-
-However, keep in mind that all documents are subject to "bit rot".
-Refer to the source code if things are not working as described here.
-
-Please send questions/comments/patches about Linux PCI API to the
-"Linux PCI" <linux-pci@atrey.karlin.mff.cuni.cz> mailing list.
-
-
-
-0. Structure of PCI drivers
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-PCI drivers "discover" PCI devices in a system via pci_register_driver().
-Actually, it's the other way around. When the PCI generic code discovers
-a new device, the driver with a matching "description" will be notified.
-Details on this below.
-
-pci_register_driver() leaves most of the probing for devices to
-the PCI layer and supports online insertion/removal of devices [thus
-supporting hot-pluggable PCI, CardBus, and Express-Card in a single driver].
-pci_register_driver() call requires passing in a table of function
-pointers and thus dictates the high level structure of a driver.
-
-Once the driver knows about a PCI device and takes ownership, the
-driver generally needs to perform the following initialization:
-
- Enable the device
- Request MMIO/IOP resources
- Set the DMA mask size (for both coherent and streaming DMA)
- Allocate and initialize shared control data (pci_allocate_coherent())
- Access device configuration space (if needed)
- Register IRQ handler (request_irq())
- Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip)
- Enable DMA/processing engines
-
-When done using the device, and perhaps the module needs to be unloaded,
-the driver needs to take the follow steps:
- Disable the device from generating IRQs
- Release the IRQ (free_irq())
- Stop all DMA activity
- Release DMA buffers (both streaming and coherent)
- Unregister from other subsystems (e.g. scsi or netdev)
- Release MMIO/IOP resources
- Disable the device
-
-Most of these topics are covered in the following sections.
-For the rest look at LDD3 or <linux/pci.h> .
-
-If the PCI subsystem is not configured (CONFIG_PCI is not set), most of
-the PCI functions described below are defined as inline functions either
-completely empty or just returning an appropriate error codes to avoid
-lots of ifdefs in the drivers.
-
-
-
-1. pci_register_driver() call
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-PCI device drivers call pci_register_driver() during their
-initialization with a pointer to a structure describing the driver
-(struct pci_driver):
-
- field name Description
- ---------- ------------------------------------------------------
- id_table Pointer to table of device ID's the driver is
- interested in. Most drivers should export this
- table using MODULE_DEVICE_TABLE(pci,...).
-
- probe This probing function gets called (during execution
- of pci_register_driver() for already existing
- devices or later if a new device gets inserted) for
- all PCI devices which match the ID table and are not
- "owned" by the other drivers yet. This function gets
- passed a "struct pci_dev *" for each device whose
- entry in the ID table matches the device. The probe
- function returns zero when the driver chooses to
- take "ownership" of the device or an error code
- (negative number) otherwise.
- The probe function always gets called from process
- context, so it can sleep.
-
- remove The remove() function gets called whenever a device
- being handled by this driver is removed (either during
- deregistration of the driver or when it's manually
- pulled out of a hot-pluggable slot).
- The remove function always gets called from process
- context, so it can sleep.
-
- suspend Put device into low power state.
- suspend_late Put device into low power state.
-
- resume_early Wake device from low power state.
- resume Wake device from low power state.
-
- (Please see Documentation/power/pci.txt for descriptions
- of PCI Power Management and the related functions.)
-
- shutdown Hook into reboot_notifier_list (kernel/sys.c).
- Intended to stop any idling DMA operations.
- Useful for enabling wake-on-lan (NIC) or changing
- the power state of a device before reboot.
- e.g. drivers/net/e100.c.
-
- err_handler See Documentation/pci-error-recovery.txt
-
-
-The ID table is an array of struct pci_device_id entries ending with an
-all-zero entry; use of the macro DEFINE_PCI_DEVICE_TABLE is the preferred
-method of declaring the table. Each entry consists of:
-
- vendor,device Vendor and device ID to match (or PCI_ANY_ID)
-
- subvendor, Subsystem vendor and device ID to match (or PCI_ANY_ID)
- subdevice,
-
- class Device class, subclass, and "interface" to match.
- See Appendix D of the PCI Local Bus Spec or
- include/linux/pci_ids.h for a full list of classes.
- Most drivers do not need to specify class/class_mask
- as vendor/device is normally sufficient.
-
- class_mask limit which sub-fields of the class field are compared.
- See drivers/scsi/sym53c8xx_2/ for example of usage.
-
- driver_data Data private to the driver.
- Most drivers don't need to use driver_data field.
- Best practice is to use driver_data as an index
- into a static list of equivalent device types,
- instead of using it as a pointer.
-
-
-Most drivers only need PCI_DEVICE() or PCI_DEVICE_CLASS() to set up
-a pci_device_id table.
-
-New PCI IDs may be added to a device driver pci_ids table at runtime
-as shown below:
-
-echo "vendor device subvendor subdevice class class_mask driver_data" > \
-/sys/bus/pci/drivers/{driver}/new_id
-
-All fields are passed in as hexadecimal values (no leading 0x).
-The vendor and device fields are mandatory, the others are optional. Users
-need pass only as many optional fields as necessary:
- o subvendor and subdevice fields default to PCI_ANY_ID (FFFFFFFF)
- o class and classmask fields default to 0
- o driver_data defaults to 0UL.
-
-Once added, the driver probe routine will be invoked for any unclaimed
-PCI devices listed in its (newly updated) pci_ids list.
-
-When the driver exits, it just calls pci_unregister_driver() and the PCI layer
-automatically calls the remove hook for all devices handled by the driver.
-
-
-1.1 "Attributes" for driver functions/data
-
-Please mark the initialization and cleanup functions where appropriate
-(the corresponding macros are defined in <linux/init.h>):
-
- __init Initialization code. Thrown away after the driver
- initializes.
- __exit Exit code. Ignored for non-modular drivers.
-
-
- __devinit Device initialization code.
- Identical to __init if the kernel is not compiled
- with CONFIG_HOTPLUG, normal function otherwise.
- __devexit The same for __exit.
-
-Tips on when/where to use the above attributes:
- o The module_init()/module_exit() functions (and all
- initialization functions called _only_ from these)
- should be marked __init/__exit.
-
- o Do not mark the struct pci_driver.
-
- o The ID table array should be marked __devinitconst; this is done
- automatically if the table is declared with DEFINE_PCI_DEVICE_TABLE().
-
- o The probe() and remove() functions should be marked __devinit
- and __devexit respectively. All initialization functions
- exclusively called by the probe() routine, can be marked __devinit.
- Ditto for remove() and __devexit.
-
- o If mydriver_remove() is marked with __devexit(), then all address
- references to mydriver_remove must use __devexit_p(mydriver_remove)
- (in the struct pci_driver declaration for example).
- __devexit_p() will generate the function name _or_ NULL if the
- function will be discarded. For an example, see drivers/net/tg3.c.
-
- o Do NOT mark a function if you are not sure which mark to use.
- Better to not mark the function than mark the function wrong.
-
-
-
-2. How to find PCI devices manually
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-PCI drivers should have a really good reason for not using the
-pci_register_driver() interface to search for PCI devices.
-The main reason PCI devices are controlled by multiple drivers
-is because one PCI device implements several different HW services.
-E.g. combined serial/parallel port/floppy controller.
-
-A manual search may be performed using the following constructs:
-
-Searching by vendor and device ID:
-
- struct pci_dev *dev = NULL;
- while (dev = pci_get_device(VENDOR_ID, DEVICE_ID, dev))
- configure_device(dev);
-
-Searching by class ID (iterate in a similar way):
-
- pci_get_class(CLASS_ID, dev)
-
-Searching by both vendor/device and subsystem vendor/device ID:
-
- pci_get_subsys(VENDOR_ID,DEVICE_ID, SUBSYS_VENDOR_ID, SUBSYS_DEVICE_ID, dev).
-
-You can use the constant PCI_ANY_ID as a wildcard replacement for
-VENDOR_ID or DEVICE_ID. This allows searching for any device from a
-specific vendor, for example.
-
-These functions are hotplug-safe. They increment the reference count on
-the pci_dev that they return. You must eventually (possibly at module unload)
-decrement the reference count on these devices by calling pci_dev_put().
-
-
-
-3. Device Initialization Steps
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-As noted in the introduction, most PCI drivers need the following steps
-for device initialization:
-
- Enable the device
- Request MMIO/IOP resources
- Set the DMA mask size (for both coherent and streaming DMA)
- Allocate and initialize shared control data (pci_allocate_coherent())
- Access device configuration space (if needed)
- Register IRQ handler (request_irq())
- Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip)
- Enable DMA/processing engines.
-
-The driver can access PCI config space registers at any time.
-(Well, almost. When running BIST, config space can go away...but
-that will just result in a PCI Bus Master Abort and config reads
-will return garbage).
-
-
-3.1 Enable the PCI device
-~~~~~~~~~~~~~~~~~~~~~~~~~
-Before touching any device registers, the driver needs to enable
-the PCI device by calling pci_enable_device(). This will:
- o wake up the device if it was in suspended state,
- o allocate I/O and memory regions of the device (if BIOS did not),
- o allocate an IRQ (if BIOS did not).
-
-NOTE: pci_enable_device() can fail! Check the return value.
-
-[ OS BUG: we don't check resource allocations before enabling those
- resources. The sequence would make more sense if we called
- pci_request_resources() before calling pci_enable_device().
- Currently, the device drivers can't detect the bug when when two
- devices have been allocated the same range. This is not a common
- problem and unlikely to get fixed soon.
-
- This has been discussed before but not changed as of 2.6.19:
- http://lkml.org/lkml/2006/3/2/194
-]
-
-pci_set_master() will enable DMA by setting the bus master bit
-in the PCI_COMMAND register. It also fixes the latency timer value if
-it's set to something bogus by the BIOS.
-
-If the PCI device can use the PCI Memory-Write-Invalidate transaction,
-call pci_set_mwi(). This enables the PCI_COMMAND bit for Mem-Wr-Inval
-and also ensures that the cache line size register is set correctly.
-Check the return value of pci_set_mwi() as not all architectures
-or chip-sets may support Memory-Write-Invalidate. Alternatively,
-if Mem-Wr-Inval would be nice to have but is not required, call
-pci_try_set_mwi() to have the system do its best effort at enabling
-Mem-Wr-Inval.
-
-
-3.2 Request MMIO/IOP resources
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Memory (MMIO), and I/O port addresses should NOT be read directly
-from the PCI device config space. Use the values in the pci_dev structure
-as the PCI "bus address" might have been remapped to a "host physical"
-address by the arch/chip-set specific kernel support.
-
-See Documentation/IO-mapping.txt for how to access device registers
-or device memory.
-
-The device driver needs to call pci_request_region() to verify
-no other device is already using the same address resource.
-Conversely, drivers should call pci_release_region() AFTER
-calling pci_disable_device().
-The idea is to prevent two devices colliding on the same address range.
-
-[ See OS BUG comment above. Currently (2.6.19), The driver can only
- determine MMIO and IO Port resource availability _after_ calling
- pci_enable_device(). ]
-
-Generic flavors of pci_request_region() are request_mem_region()
-(for MMIO ranges) and request_region() (for IO Port ranges).
-Use these for address resources that are not described by "normal" PCI
-BARs.
-
-Also see pci_request_selected_regions() below.
-
-
-3.3 Set the DMA mask size
-~~~~~~~~~~~~~~~~~~~~~~~~~
-[ If anything below doesn't make sense, please refer to
- Documentation/DMA-API.txt. This section is just a reminder that
- drivers need to indicate DMA capabilities of the device and is not
- an authoritative source for DMA interfaces. ]
-
-While all drivers should explicitly indicate the DMA capability
-(e.g. 32 or 64 bit) of the PCI bus master, devices with more than
-32-bit bus master capability for streaming data need the driver
-to "register" this capability by calling pci_set_dma_mask() with
-appropriate parameters. In general this allows more efficient DMA
-on systems where System RAM exists above 4G _physical_ address.
-
-Drivers for all PCI-X and PCIe compliant devices must call
-pci_set_dma_mask() as they are 64-bit DMA devices.
-
-Similarly, drivers must also "register" this capability if the device
-can directly address "consistent memory" in System RAM above 4G physical
-address by calling pci_set_consistent_dma_mask().
-Again, this includes drivers for all PCI-X and PCIe compliant devices.
-Many 64-bit "PCI" devices (before PCI-X) and some PCI-X devices are
-64-bit DMA capable for payload ("streaming") data but not control
-("consistent") data.
-
-
-3.4 Setup shared control data
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Once the DMA masks are set, the driver can allocate "consistent" (a.k.a. shared)
-memory. See Documentation/DMA-API.txt for a full description of
-the DMA APIs. This section is just a reminder that it needs to be done
-before enabling DMA on the device.
-
-
-3.5 Initialize device registers
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Some drivers will need specific "capability" fields programmed
-or other "vendor specific" register initialized or reset.
-E.g. clearing pending interrupts.
-
-
-3.6 Register IRQ handler
-~~~~~~~~~~~~~~~~~~~~~~~~
-While calling request_irq() is the last step described here,
-this is often just another intermediate step to initialize a device.
-This step can often be deferred until the device is opened for use.
-
-All interrupt handlers for IRQ lines should be registered with IRQF_SHARED
-and use the devid to map IRQs to devices (remember that all PCI IRQ lines
-can be shared).
-
-request_irq() will associate an interrupt handler and device handle
-with an interrupt number. Historically interrupt numbers represent
-IRQ lines which run from the PCI device to the Interrupt controller.
-With MSI and MSI-X (more below) the interrupt number is a CPU "vector".
-
-request_irq() also enables the interrupt. Make sure the device is
-quiesced and does not have any interrupts pending before registering
-the interrupt handler.
-
-MSI and MSI-X are PCI capabilities. Both are "Message Signaled Interrupts"
-which deliver interrupts to the CPU via a DMA write to a Local APIC.
-The fundamental difference between MSI and MSI-X is how multiple
-"vectors" get allocated. MSI requires contiguous blocks of vectors
-while MSI-X can allocate several individual ones.
-
-MSI capability can be enabled by calling pci_enable_msi() or
-pci_enable_msix() before calling request_irq(). This causes
-the PCI support to program CPU vector data into the PCI device
-capability registers.
-
-If your PCI device supports both, try to enable MSI-X first.
-Only one can be enabled at a time. Many architectures, chip-sets,
-or BIOSes do NOT support MSI or MSI-X and the call to pci_enable_msi/msix
-will fail. This is important to note since many drivers have
-two (or more) interrupt handlers: one for MSI/MSI-X and another for IRQs.
-They choose which handler to register with request_irq() based on the
-return value from pci_enable_msi/msix().
-
-There are (at least) two really good reasons for using MSI:
-1) MSI is an exclusive interrupt vector by definition.
- This means the interrupt handler doesn't have to verify
- its device caused the interrupt.
-
-2) MSI avoids DMA/IRQ race conditions. DMA to host memory is guaranteed
- to be visible to the host CPU(s) when the MSI is delivered. This
- is important for both data coherency and avoiding stale control data.
- This guarantee allows the driver to omit MMIO reads to flush
- the DMA stream.
-
-See drivers/infiniband/hw/mthca/ or drivers/net/tg3.c for examples
-of MSI/MSI-X usage.
-
-
-
-4. PCI device shutdown
-~~~~~~~~~~~~~~~~~~~~~~~
-
-When a PCI device driver is being unloaded, most of the following
-steps need to be performed:
-
- Disable the device from generating IRQs
- Release the IRQ (free_irq())
- Stop all DMA activity
- Release DMA buffers (both streaming and consistent)
- Unregister from other subsystems (e.g. scsi or netdev)
- Disable device from responding to MMIO/IO Port addresses
- Release MMIO/IO Port resource(s)
-
-
-4.1 Stop IRQs on the device
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-How to do this is chip/device specific. If it's not done, it opens
-the possibility of a "screaming interrupt" if (and only if)
-the IRQ is shared with another device.
-
-When the shared IRQ handler is "unhooked", the remaining devices
-using the same IRQ line will still need the IRQ enabled. Thus if the
-"unhooked" device asserts IRQ line, the system will respond assuming
-it was one of the remaining devices asserted the IRQ line. Since none
-of the other devices will handle the IRQ, the system will "hang" until
-it decides the IRQ isn't going to get handled and masks the IRQ (100,000
-iterations later). Once the shared IRQ is masked, the remaining devices
-will stop functioning properly. Not a nice situation.
-
-This is another reason to use MSI or MSI-X if it's available.
-MSI and MSI-X are defined to be exclusive interrupts and thus
-are not susceptible to the "screaming interrupt" problem.
-
-
-4.2 Release the IRQ
-~~~~~~~~~~~~~~~~~~~
-Once the device is quiesced (no more IRQs), one can call free_irq().
-This function will return control once any pending IRQs are handled,
-"unhook" the drivers IRQ handler from that IRQ, and finally release
-the IRQ if no one else is using it.
-
-
-4.3 Stop all DMA activity
-~~~~~~~~~~~~~~~~~~~~~~~~~
-It's extremely important to stop all DMA operations BEFORE attempting
-to deallocate DMA control data. Failure to do so can result in memory
-corruption, hangs, and on some chip-sets a hard crash.
-
-Stopping DMA after stopping the IRQs can avoid races where the
-IRQ handler might restart DMA engines.
-
-While this step sounds obvious and trivial, several "mature" drivers
-didn't get this step right in the past.
-
-
-4.4 Release DMA buffers
-~~~~~~~~~~~~~~~~~~~~~~~
-Once DMA is stopped, clean up streaming DMA first.
-I.e. unmap data buffers and return buffers to "upstream"
-owners if there is one.
-
-Then clean up "consistent" buffers which contain the control data.
-
-See Documentation/DMA-API.txt for details on unmapping interfaces.
-
-
-4.5 Unregister from other subsystems
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Most low level PCI device drivers support some other subsystem
-like USB, ALSA, SCSI, NetDev, Infiniband, etc. Make sure your
-driver isn't losing resources from that other subsystem.
-If this happens, typically the symptom is an Oops (panic) when
-the subsystem attempts to call into a driver that has been unloaded.
-
-
-4.6 Disable Device from responding to MMIO/IO Port addresses
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-io_unmap() MMIO or IO Port resources and then call pci_disable_device().
-This is the symmetric opposite of pci_enable_device().
-Do not access device registers after calling pci_disable_device().
-
-
-4.7 Release MMIO/IO Port Resource(s)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Call pci_release_region() to mark the MMIO or IO Port range as available.
-Failure to do so usually results in the inability to reload the driver.
-
-
-
-5. How to access PCI config space
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can use pci_(read|write)_config_(byte|word|dword) to access the config
-space of a device represented by struct pci_dev *. All these functions return 0
-when successful or an error code (PCIBIOS_...) which can be translated to a text
-string by pcibios_strerror. Most drivers expect that accesses to valid PCI
-devices don't fail.
-
-If you don't have a struct pci_dev available, you can call
-pci_bus_(read|write)_config_(byte|word|dword) to access a given device
-and function on that bus.
-
-If you access fields in the standard portion of the config header, please
-use symbolic names of locations and bits declared in <linux/pci.h>.
-
-If you need to access Extended PCI Capability registers, just call
-pci_find_capability() for the particular capability and it will find the
-corresponding register block for you.
-
-
-
-6. Other interesting functions
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-pci_find_slot() Find pci_dev corresponding to given bus and
- slot numbers.
-pci_set_power_state() Set PCI Power Management state (0=D0 ... 3=D3)
-pci_find_capability() Find specified capability in device's capability
- list.
-pci_resource_start() Returns bus start address for a given PCI region
-pci_resource_end() Returns bus end address for a given PCI region
-pci_resource_len() Returns the byte length of a PCI region
-pci_set_drvdata() Set private driver data pointer for a pci_dev
-pci_get_drvdata() Return private driver data pointer for a pci_dev
-pci_set_mwi() Enable Memory-Write-Invalidate transactions.
-pci_clear_mwi() Disable Memory-Write-Invalidate transactions.
-
-
-
-7. Miscellaneous hints
-~~~~~~~~~~~~~~~~~~~~~~
-
-When displaying PCI device names to the user (for example when a driver wants
-to tell the user what card has it found), please use pci_name(pci_dev).
-
-Always refer to the PCI devices by a pointer to the pci_dev structure.
-All PCI layer functions use this identification and it's the only
-reasonable one. Don't use bus/slot/function numbers except for very
-special purposes -- on systems with multiple primary buses their semantics
-can be pretty complex.
-
-Don't try to turn on Fast Back to Back writes in your driver. All devices
-on the bus need to be capable of doing it, so this is something which needs
-to be handled by platform and generic code, not individual drivers.
-
-
-
-8. Vendor and device identifications
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-One is not not required to add new device ids to include/linux/pci_ids.h.
-Please add PCI_VENDOR_ID_xxx for vendors and a hex constant for device ids.
-
-PCI_VENDOR_ID_xxx constants are re-used. The device ids are arbitrary
-hex numbers (vendor controlled) and normally used only in a single
-location, the pci_device_id table.
-
-Please DO submit new vendor/device ids to pciids.sourceforge.net project.
-
-
-
-9. Obsolete functions
-~~~~~~~~~~~~~~~~~~~~~
-
-There are several functions which you might come across when trying to
-port an old driver to the new PCI interface. They are no longer present
-in the kernel as they aren't compatible with hotplug or PCI domains or
-having sane locking.
-
-pci_find_device() Superseded by pci_get_device()
-pci_find_subsys() Superseded by pci_get_subsys()
-pci_find_slot() Superseded by pci_get_slot()
-
-
-The alternative is the traditional PCI device driver that walks PCI
-device lists. This is still possible but discouraged.
-
-
-
-10. MMIO Space and "Write Posting"
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Converting a driver from using I/O Port space to using MMIO space
-often requires some additional changes. Specifically, "write posting"
-needs to be handled. Many drivers (e.g. tg3, acenic, sym53c8xx_2)
-already do this. I/O Port space guarantees write transactions reach the PCI
-device before the CPU can continue. Writes to MMIO space allow the CPU
-to continue before the transaction reaches the PCI device. HW weenies
-call this "Write Posting" because the write completion is "posted" to
-the CPU before the transaction has reached its destination.
-
-Thus, timing sensitive code should add readl() where the CPU is
-expected to wait before doing other work. The classic "bit banging"
-sequence works fine for I/O Port space:
-
- for (i = 8; --i; val >>= 1) {
- outb(val & 1, ioport_reg); /* write bit */
- udelay(10);
- }
-
-The same sequence for MMIO space should be:
-
- for (i = 8; --i; val >>= 1) {
- writeb(val & 1, mmio_reg); /* write bit */
- readb(safe_mmio_reg); /* flush posted write */
- udelay(10);
- }
-
-It is important that "safe_mmio_reg" not have any side effects that
-interferes with the correct operation of the device.
-
-Another case to watch out for is when resetting a PCI device. Use PCI
-Configuration space reads to flush the writel(). This will gracefully
-handle the PCI master abort on all platforms if the PCI device is
-expected to not respond to a readl(). Most x86 platforms will allow
-MMIO reads to master abort (a.k.a. "Soft Fail") and return garbage
-(e.g. ~0). But many RISC platforms will crash (a.k.a."Hard Fail").

- The PCI Express Advanced Error Reporting Driver Guide HOWTO
- T. Long Nguyen <tom.l.nguyen@intel.com>
- Yanmin Zhang <yanmin.zhang@intel.com>
- 07/29/2006
-
-
-1. Overview
-
-1.1 About this guide
-
-This guide describes the basics of the PCI Express Advanced Error
-Reporting (AER) driver and provides information on how to use it, as
-well as how to enable the drivers of endpoint devices to conform with
-PCI Express AER driver.
-
-1.2 Copyright © Intel Corporation 2006.
-
-1.3 What is the PCI Express AER Driver?
-
-PCI Express error signaling can occur on the PCI Express link itself
-or on behalf of transactions initiated on the link. PCI Express
-defines two error reporting paradigms: the baseline capability and
-the Advanced Error Reporting capability. The baseline capability is
-required of all PCI Express components providing a minimum defined
-set of error reporting requirements. Advanced Error Reporting
-capability is implemented with a PCI Express advanced error reporting
-extended capability structure providing more robust error reporting.
-
-The PCI Express AER driver provides the infrastructure to support PCI
-Express Advanced Error Reporting capability. The PCI Express AER
-driver provides three basic functions:
-
-- Gathers the comprehensive error information if errors occurred.
-- Reports error to the users.
-- Performs error recovery actions.
-
-AER driver only attaches root ports which support PCI-Express AER
-capability.
-
-
-2. User Guide
-
-2.1 Include the PCI Express AER Root Driver into the Linux Kernel
-
-The PCI Express AER Root driver is a Root Port service driver attached
-to the PCI Express Port Bus driver. If a user wants to use it, the driver
-has to be compiled. Option CONFIG_PCIEAER supports this capability. It
-depends on CONFIG_PCIEPORTBUS, so pls. set CONFIG_PCIEPORTBUS=y and
-CONFIG_PCIEAER = y.
-
-2.2 Load PCI Express AER Root Driver
-There is a case where a system has AER support in BIOS. Enabling the AER
-Root driver and having AER support in BIOS may result unpredictable
-behavior. To avoid this conflict, a successful load of the AER Root driver
-requires ACPI _OSC support in the BIOS to allow the AER Root driver to
-request for native control of AER. See the PCI FW 3.0 Specification for
-details regarding OSC usage. Currently, lots of firmwares don't provide
-_OSC support while they use PCI Express. To support such firmwares,
-forceload, a parameter of type bool, could enable AER to continue to
-be initiated although firmwares have no _OSC support. To enable the
-walkaround, pls. add aerdriver.forceload=y to kernel boot parameter line
-when booting kernel. Note that forceload=n by default.
-
-2.3 AER error output
-When a PCI-E AER error is captured, an error message will be outputed to
-console. If it's a correctable error, it is outputed as a warning.
-Otherwise, it is printed as an error. So users could choose different
-log level to filter out correctable error messages.
-
-Below shows an example.
-+------ PCI-Express Device Error -----+
-Error Severity : Uncorrected (Fatal)
-PCIE Bus Error type : Transaction Layer
-Unsupported Request : First
-Requester ID : 0500
-VendorID=8086h, DeviceID=0329h, Bus=05h, Device=00h, Function=00h
-TLB Header:
-04000001 00200a03 05010000 00050100
-
-In the example, 'Requester ID' means the ID of the device who sends
-the error message to root port. Pls. refer to pci express specs for
-other fields.
-
-
-3. Developer Guide
-
-To enable AER aware support requires a software driver to configure
-the AER capability structure within its device and to provide callbacks.
-
-To support AER better, developers need understand how AER does work
-firstly.
-
-PCI Express errors are classified into two types: correctable errors
-and uncorrectable errors. This classification is based on the impacts
-of those errors, which may result in degraded performance or function
-failure.
-
-Correctable errors pose no impacts on the functionality of the
-interface. The PCI Express protocol can recover without any software
-intervention or any loss of data. These errors are detected and
-corrected by hardware. Unlike correctable errors, uncorrectable
-errors impact functionality of the interface. Uncorrectable errors
-can cause a particular transaction or a particular PCI Express link
-to be unreliable. Depending on those error conditions, uncorrectable
-errors are further classified into non-fatal errors and fatal errors.
-Non-fatal errors cause the particular transaction to be unreliable,
-but the PCI Express link itself is fully functional. Fatal errors, on
-the other hand, cause the link to be unreliable.
-
-When AER is enabled, a PCI Express device will automatically send an
-error message to the PCIE root port above it when the device captures
-an error. The Root Port, upon receiving an error reporting message,
-internally processes and logs the error message in its PCI Express
-capability structure. Error information being logged includes storing
-the error reporting agent's requestor ID into the Error Source
-Identification Registers and setting the error bits of the Root Error
-Status Register accordingly. If AER error reporting is enabled in Root
-Error Command Register, the Root Port generates an interrupt if an
-error is detected.
-
-Note that the errors as described above are related to the PCI Express
-hierarchy and links. These errors do not include any device specific
-errors because device specific errors will still get sent directly to
-the device driver.
-
-3.1 Configure the AER capability structure
-
-AER aware drivers of PCI Express component need change the device
-control registers to enable AER. They also could change AER registers,
-including mask and severity registers. Helper function
-pci_enable_pcie_error_reporting could be used to enable AER. See
-section 3.3.
-
-3.2. Provide callbacks
-
-3.2.1 callback reset_link to reset pci express link
-
-This callback is used to reset the pci express physical link when a
-fatal error happens. The root port aer service driver provides a
-default reset_link function, but different upstream ports might
-have different specifications to reset pci express link, so all
-upstream ports should provide their own reset_link functions.
-
-In struct pcie_port_service_driver, a new pointer, reset_link, is
-added.
-
-pci_ers_result_t (*reset_link) (struct pci_dev *dev);
-
-Section 3.2.2.2 provides more detailed info on when to call
-reset_link.
-
-3.2.2 PCI error-recovery callbacks
-
-The PCI Express AER Root driver uses error callbacks to coordinate
-with downstream device drivers associated with a hierarchy in question
-when performing error recovery actions.
-
-Data struct pci_driver has a pointer, err_handler, to point to
-pci_error_handlers who consists of a couple of callback function
-pointers. AER driver follows the rules defined in
-pci-error-recovery.txt except pci express specific parts (e.g.
-reset_link). Pls. refer to pci-error-recovery.txt for detailed
-definitions of the callbacks.
-
-Below sections specify when to call the error callback functions.
-
-3.2.2.1 Correctable errors
-
-Correctable errors pose no impacts on the functionality of
-the interface. The PCI Express protocol can recover without any
-software intervention or any loss of data. These errors do not
-require any recovery actions. The AER driver clears the device's
-correctable error status register accordingly and logs these errors.
-
-3.2.2.2 Non-correctable (non-fatal and fatal) errors
-
-If an error message indicates a non-fatal error, performing link reset
-at upstream is not required. The AER driver calls error_detected(dev,
-pci_channel_io_normal) to all drivers associated within a hierarchy in
-question. for example,
-EndPoint<==>DownstreamPort B<==>UpstreamPort A<==>RootPort.
-If Upstream port A captures an AER error, the hierarchy consists of
-Downstream port B and EndPoint.
-
-A driver may return PCI_ERS_RESULT_CAN_RECOVER,
-PCI_ERS_RESULT_DISCONNECT, or PCI_ERS_RESULT_NEED_RESET, depending on
-whether it can recover or the AER driver calls mmio_enabled as next.
-
-If an error message indicates a fatal error, kernel will broadcast
-error_detected(dev, pci_channel_io_frozen) to all drivers within
-a hierarchy in question. Then, performing link reset at upstream is
-necessary. As different kinds of devices might use different approaches
-to reset link, AER port service driver is required to provide the
-function to reset link. Firstly, kernel looks for if the upstream
-component has an aer driver. If it has, kernel uses the reset_link
-callback of the aer driver. If the upstream component has no aer driver
-and the port is downstream port, we will use the aer driver of the
-root port who reports the AER error. As for upstream ports,
-they should provide their own aer service drivers with reset_link
-function. If error_detected returns PCI_ERS_RESULT_CAN_RECOVER and
-reset_link returns PCI_ERS_RESULT_RECOVERED, the error handling goes
-to mmio_enabled.
-
-3.3 helper functions
-
-3.3.1 int pci_find_aer_capability(struct pci_dev *dev);
-pci_find_aer_capability locates the PCI Express AER capability
-in the device configuration space. If the device doesn't support
-PCI-Express AER, the function returns 0.
-
-3.3.2 int pci_enable_pcie_error_reporting(struct pci_dev *dev);
-pci_enable_pcie_error_reporting enables the device to send error
-messages to root port when an error is detected. Note that devices
-don't enable the error reporting by default, so device drivers need
-call this function to enable it.
-
-3.3.3 int pci_disable_pcie_error_reporting(struct pci_dev *dev);
-pci_disable_pcie_error_reporting disables the device to send error
-messages to root port when an error is detected.
-
-3.3.4 int pci_cleanup_aer_uncorrect_error_status(struct pci_dev *dev);
-pci_cleanup_aer_uncorrect_error_status cleanups the uncorrectable
-error status register.
-
-3.4 Frequent Asked Questions
-
-Q: What happens if a PCI Express device driver does not provide an
-error recovery handler (pci_driver->err_handler is equal to NULL)?
-
-A: The devices attached with the driver won't be recovered. If the
-error is fatal, kernel will print out warning messages. Please refer
-to section 3 for more information.
-
-Q: What happens if an upstream port service driver does not provide
-callback reset_link?
-
-A: Fatal error recovery will fail if the errors are reported by the
-upstream ports who are attached by the service driver.
-
-Q: How does this infrastructure deal with driver that is not PCI
-Express aware?
-
-A: This infrastructure calls the error callback functions of the
-driver when an error happens. But if the driver is not aware of
-PCI Express, the device might not report its own errors to root
-port.
-
-Q: What modifications will that driver need to make it compatible
-with the PCI Express AER Root driver?
-
-A: It could call the helper functions to enable AER in devices and
-cleanup uncorrectable status register. Pls. refer to section 3.3.

+===========================================================
+
+The Marvell mv64[345]60 series of system controller chips contain
+many of the peripherals needed to implement a complete computer
+system. In this section, we define device tree nodes to describe
+the system controller chip itself and each of the peripherals
+which it contains. Compatible string values for each node are
+prefixed with the string "marvell,", for Marvell Technology Group Ltd.
+
+1) The /system-controller node
+
+ This node is used to represent the system-controller and must be
+ present when the system uses a system contller chip. The top-level
+ system-controller node contains information that is global to all
+ devices within the system controller chip. The node name begins
+ with "system-controller" followed by the unit address, which is
+ the base address of the memory-mapped register set for the system
+ controller chip.
+
+ Required properties:
+
+ - ranges : Describes the translation of system controller addresses
+ for memory mapped registers.
+ - clock-frequency: Contains the main clock frequency for the system
+ controller chip.
+ - reg : This property defines the address and size of the
+ memory-mapped registers contained within the system controller
+ chip. The address specified in the "reg" property should match
+ the unit address of the system-controller node.
+ - #address-cells : Address representation for system controller
+ devices. This field represents the number of cells needed to
+ represent the address of the memory-mapped registers of devices
+ within the system controller chip.
+ - #size-cells : Size representation for for the memory-mapped
+ registers within the system controller chip.
+ - #interrupt-cells : Defines the width of cells used to represent
+ interrupts.
+
+ Optional properties:
+
+ - model : The specific model of the system controller chip. Such
+ as, "mv64360", "mv64460", or "mv64560".
+ - compatible : A string identifying the compatibility identifiers
+ of the system controller chip.
+
+ The system-controller node contains child nodes for each system
+ controller device that the platform uses. Nodes should not be created
+ for devices which exist on the system controller chip but are not used
+
+ Example Marvell Discovery mv64360 system-controller node:
+
+ system-controller@f1000000 { /* Marvell Discovery mv64360 */
+ #address-cells = <1>;
+ #size-cells = <1>;
+ model = "mv64360"; /* Default */
+ compatible = "marvell,mv64360";
+ clock-frequency = <133333333>;
+ reg = <0xf1000000 0x10000>;
+ virtual-reg = <0xf1000000>;

+
+2) Child nodes of /system-controller
+
+ a) Marvell Discovery MDIO bus
+
+ The MDIO is a bus to which the PHY devices are connected. For each
+ device that exists on this bus, a child node should be created. See
+ the definition of the PHY node below for an example of how to define
+ a PHY.
+
+ Required properties:
+ - #address-cells : Should be <1>
+ - #size-cells : Should be <0>
+ - device_type : Should be "mdio"
+ - compatible : Should be "marvell,mv64360-mdio"
+
+ Example:
+
+ mdio {

+
+ b) Marvell Discovery ethernet controller
+
+ The Discover ethernet controller is described with two levels
+ of nodes. The first level describes an ethernet silicon block
+ and the second level describes up to 3 ethernet nodes within
+ that block. The reason for the multiple levels is that the
+ registers for the node are interleaved within a single set
+ of registers. The "ethernet-block" level describes the
+ shared register set, and the "ethernet" nodes describe ethernet
+ port-specific properties.

+
+Various notes on the implementation of KVM for PowerPC 440:
+
+To enforce isolation, host userspace, guest kernel, and guest userspace all
+run at user privilege level. Only the host kernel runs in supervisor mode.
+Executing privileged instructions in the guest traps into KVM (in the host
+kernel), where we decode and emulate them. Through this technique, unmodified
+440 Linux kernels can be run (slowly) as guests. Future performance work will
+focus on reducing the overhead and frequency of these traps.
+
+The usual code flow is started from userspace invoking an "run" ioctl, which
+causes KVM to switch into guest context. We use IVPR to hijack the host
+interrupt vectors while running the guest, which allows us to direct all
+interrupts to kvmppc_handle_interrupt(). At this point, we could either
+- handle the interrupt completely (e.g. emulate "mtspr SPRG0"), or
+- let the host interrupt handler run (e.g. when the decrementer fires), or
+- return to host userspace (e.g. when the guest performs device MMIO)
+
+Address spaces: We take advantage of the fact that Linux doesn't use the AS=1
+address space (in host or guest), which gives us virtual address space to use
+for guest mappings. While the guest is running, the host kernel remains mapped
+in AS=0, but the guest can only use AS=1 mappings.
+
+TLB entries: The TLB entries covering the host linear mapping remain
+present while running the guest. This reduces the overhead of lightweight
+exits, which are handled by KVM running in the host kernel. We keep three
+copies of the TLB:
+ - guest TLB: contents of the TLB as the guest sees it
+ - shadow TLB: the TLB that is actually in hardware while guest is running
+ - host TLB: to restore TLB state when context switching guest -> host
+When a TLB miss occurs because a mapping was not present in the shadow TLB,
+but was present in the guest TLB, KVM handles the fault without invoking the
+guest. Large guest pages are backed by multiple 4KB shadow pages through this
+mechanism.
+
+IO: MMIO and DCR accesses are emulated by userspace. We use virtio for network
+and block IO, so those drivers must be enabled in the guest. It's possible
+that some qemu device emulation (e.g. e1000 or rtl8139) may also work with
+little effort.

+
+ Hypervisor-Assisted Dump
+ ------------------------
+ November 2007
+
+The goal of hypervisor-assisted dump is to enable the dump of
+a crashed system, and to do so from a fully-reset system, and
+to minimize the total elapsed time until the system is back
+in production use.
+
+As compared to kdump or other strategies, hypervisor-assisted
+dump offers several strong, practical advantages:
+
+-- Unlike kdump, the system has been reset, and loaded
+ with a fresh copy of the kernel. In particular,
+ PCI and I/O devices have been reinitialized and are
+ in a clean, consistent state.
+-- As the dump is performed, the dumped memory becomes
+ immediately available to the system for normal use.
+-- After the dump is completed, no further reboots are
+ required; the system will be fully usable, and running
+ in it's normal, production mode on it normal kernel.
+
+The above can only be accomplished by coordination with,
+and assistance from the hypervisor. The procedure is
+as follows:
+
+-- When a system crashes, the hypervisor will save
+ the low 256MB of RAM to a previously registered
+ save region. It will also save system state, system
+ registers, and hardware PTE's.
+
+-- After the low 256MB area has been saved, the
+ hypervisor will reset PCI and other hardware state.
+ It will *not* clear RAM. It will then launch the
+ bootloader, as normal.
+
+-- The freshly booted kernel will notice that there
+ is a new node (ibm,dump-kernel) in the device tree,
+ indicating that there is crash data available from
+ a previous boot. It will boot into only 256MB of RAM,
+ reserving the rest of system memory.
+
+-- Userspace tools will parse /sys/kernel/release_region
+ and read /proc/vmcore to obtain the contents of memory,
+ which holds the previous crashed kernel. The userspace
+ tools may copy this info to disk, or network, nas, san,
+ iscsi, etc. as desired.
+
+ For Example: the values in /sys/kernel/release-region
+ would look something like this (address-range pairs).
+ CPU:0x177fee000-0x10000: HPTE:0x177ffe020-0x1000: /
+ DUMP:0x177fff020-0x10000000, 0x10000000-0x16F1D370A
+
+-- As the userspace tools complete saving a portion of
+ dump, they echo an offset and size to
+ /sys/kernel/release_region to release the reserved
+ memory back to general use.
+
+ An example of this is:
+ "echo 0x40000000 0x10000000 > /sys/kernel/release_region"
+ which will release 256MB at the 1GB boundary.
+
+Please note that the hypervisor-assisted dump feature
+is only available on Power6-based systems with recent
+firmware versions.
+
+Implementation details:
+----------------------
+
+During boot, a check is made to see if firmware supports
+this feature on this particular machine. If it does, then
+we check to see if a active dump is waiting for us. If yes
+then everything but 256 MB of RAM is reserved during early
+boot. This area is released once we collect a dump from user
+land scripts that are run. If there is dump data, then
+the /sys/kernel/release_region file is created, and
+the reserved memory is held.
+
+If there is no waiting dump data, then only the highest
+256MB of the ram is reserved as a scratch area. This area
+is *not* released: this region will be kept permanently
+reserved, so that it can act as a receptacle for a copy
+of the low 256MB in the case a crash does occur. See,
+however, "open issues" below, as to whether
+such a reserved region is really needed.
+
+Currently the dump will be copied from /proc/vmcore to a
+a new file upon user intervention. The starting address
+to be read and the range for each data point in provided
+in /sys/kernel/release_region.
+
+The tools to examine the dump will be same as the ones
+used for kdump.
+
+General notes:
+--------------
+Security: please note that there are potential security issues
+with any sort of dump mechanism. In particular, plaintext
+(unencrypted) data, and possibly passwords, may be present in
+the dump data. Userspace tools must take adequate precautions to
+preserve security.
+
+Open issues/ToDo:
+------------
+ o The various code paths that tell the hypervisor that a crash
+ occurred, vs. it simply being a normal reboot, should be
+ reviewed, and possibly clarified/fixed.
+
+ o Instead of using /sys/kernel, should there be a /sys/dump
+ instead? There is a dump_subsys being created by the s390 code,
+ perhaps the pseries code should use a similar layout as well.
+
+ o Is reserving a 256MB region really required? The goal of
+ reserving a 256MB scratch area is to make sure that no
+ important crash data is clobbered when the hypervisor
+ save low mem to the scratch area. But, if one could assure
+ that nothing important is located in some 256MB area, then
+ it would not need to be reserved. Something that can be
+ improved in subsequent versions.
+
+ o Still working the kdump team to integrate this with kdump,
+ some work remains but this would not affect the current
+ patches.
+
+ o Still need to write a shell script, to copy the dump away.
+ Currently I am parsing it manually.

+*** BIG FAT WARNING ***
+The kvm module is currently in EXPERIMENTAL state for s390. This means that
+the interface to the module is not yet considered to remain stable. Thus, be
+prepared that we keep breaking your userspace application and guest
+compatibility over and over again until we feel happy with the result. Make sure
+your guest kernel, your host kernel, and your userspace launcher are in a
+consistent state.
+
+This Documentation describes the unique ioctl calls to /dev/kvm, the resulting
+kvm-vm file descriptors, and the kvm-vcpu file descriptors that differ from x86.
+
+1. ioctl calls to /dev/kvm
+KVM does support the following ioctls on s390 that are common with other
+architectures and do behave the same:
+KVM_GET_API_VERSION
+KVM_CREATE_VM (*) see note
+KVM_CHECK_EXTENSION
+KVM_GET_VCPU_MMAP_SIZE
+
+Notes:
+* KVM_CREATE_VM may fail on s390, if the calling process has multiple
+threads and has not called KVM_S390_ENABLE_SIE before.
+
+In addition, on s390 the following architecture specific ioctls are supported:
+ioctl: KVM_S390_ENABLE_SIE
+args: none
+see also: include/linux/kvm.h
+This call causes the kernel to switch on PGSTE in the user page table. This
+operation is needed in order to run a virtual machine, and it requires the
+calling process to be single-threaded. Note that the first call to KVM_CREATE_VM
+will implicitly try to switch on PGSTE if the user process has not called
+KVM_S390_ENABLE_SIE before. User processes that want to launch multiple threads
+before creating a virtual machine have to call KVM_S390_ENABLE_SIE, or will
+observe an error calling KVM_CREATE_VM. Switching on PGSTE is a one-time
+operation, is not reversible, and will persist over the entire lifetime of
+the calling process. It does not have any user-visible effect other than a small
+performance penalty.
+
+2. ioctl calls to the kvm-vm file descriptor
+KVM does support the following ioctls on s390 that are common with other
+architectures and do behave the same:
+KVM_CREATE_VCPU
+KVM_SET_USER_MEMORY_REGION (*) see note
+KVM_GET_DIRTY_LOG (**) see note
+
+Notes:
+* kvm does only allow exactly one memory slot on s390, which has to start
+ at guest absolute address zero and at a user address that is aligned on any
+ page boundary. This hardware "limitation" allows us to have a few unique
+ optimizations. The memory slot doesn't have to be filled
+ with memory actually, it may contain sparse holes. That said, with different
+ user memory layout this does still allow a large flexibility when
+ doing the guest memory setup.
+** KVM_GET_DIRTY_LOG doesn't work properly yet. The user will receive an empty
+log. This ioctl call is only needed for guest migration, and we intend to
+implement this one in the future.
+
+In addition, on s390 the following architecture specific ioctls for the kvm-vm
+file descriptor are supported:
+ioctl: KVM_S390_INTERRUPT
+args: struct kvm_s390_interrupt *
+see also: include/linux/kvm.h
+This ioctl is used to submit a floating interrupt for a virtual machine.
+Floating interrupts may be delivered to any virtual cpu in the configuration.
+Only some interrupt types defined in include/linux/kvm.h make sense when
+submitted as floating interrupts. The following interrupts are not considered
+to be useful as floating interrupts, and a call to inject them will result in
+-EINVAL error code: program interrupts and interprocessor signals. Valid
+floating interrupts are:
+KVM_S390_INT_VIRTIO
+KVM_S390_INT_SERVICE
+
+3. ioctl calls to the kvm-vcpu file descriptor
+KVM does support the following ioctls on s390 that are common with other
+architectures and do behave the same:
+KVM_RUN
+KVM_GET_REGS
+KVM_SET_REGS
+KVM_GET_SREGS
+KVM_SET_SREGS
+KVM_GET_FPU
+KVM_SET_FPU
+
+In addition, on s390 the following architecture specific ioctls for the
+kvm-vcpu file descriptor are supported:
+ioctl: KVM_S390_INTERRUPT
+args: struct kvm_s390_interrupt *
+see also: include/linux/kvm.h
+This ioctl is used to submit an interrupt for a specific virtual cpu.
+Only some interrupt types defined in include/linux/kvm.h make sense when
+submitted for a specific cpu. The following interrupts are not considered
+to be useful, and a call to inject them will result in -EINVAL error code:
+service processor calls and virtio interrupts. Valid interrupt types are:
+KVM_S390_PROGRAM_INT
+KVM_S390_SIGP_STOP
+KVM_S390_RESTART
+KVM_S390_SIGP_SET_PREFIX
+KVM_S390_INT_EMERGENCY
+
+ioctl: KVM_S390_STORE_STATUS
+args: unsigned long
+see also: include/linux/kvm.h
+This ioctl stores the state of the cpu at the guest real address given as
+argument, unless one of the following values defined in include/linux/kvm.h
+is given as arguement:
+KVM_S390_STORE_STATUS_NOADDR - the CPU stores its status to the save area in
+absolute lowcore as defined by the principles of operation
+KVM_S390_STORE_STATUS_PREFIXED - the CPU stores its status to the save area in
+its prefix page just like the dump tool that comes with zipl. This is useful
+to create a system dump for use with lkcdutils or crash.
+
+ioctl: KVM_S390_SET_INITIAL_PSW
+args: struct kvm_s390_psw *
+see also: include/linux/kvm.h
+This ioctl can be used to set the processor status word (psw) of a stopped cpu
+prior to running it with KVM_RUN. Note that this call is not required to modify
+the psw during sie intercepts that fall back to userspace because struct kvm_run
+does contain the psw, and this value is evaluated during reentry of KVM_RUN
+after the intercept exit was recognized.
+
+ioctl: KVM_S390_INITIAL_RESET
+args: none
+see also: include/linux/kvm.h
+This ioctl can be used to perform an initial cpu reset as defined by the
+principles of operation. The target cpu has to be in stopped state.

+1. Overview
+===========
-The Interface:
+1.1 The problem
+---------------
-system wide:
+Realtime scheduling is all about determinism, a group has to be able to rely on
+the amount of bandwidth (eg. CPU time) being constant. In order to schedule
+multiple groups of realtime tasks, each group must be assigned a fixed portion
+of the CPU time available. Without a minimum guarantee a realtime group can
+obviously fall short. A fuzzy upper limit is of no use since it cannot be
+relied upon. Which leaves us with just the single fixed portion.
-/proc/sys/kernel/sched_rt_period_ms
-/proc/sys/kernel/sched_rt_runtime_us
+1.2 The solution
+----------------
-CONFIG_FAIR_USER_SCHED
+CPU time is divided by means of specifying how much time can be spent running
+in a given period. We allocate this "run time" for each realtime group which
+the other realtime groups will not be permitted to use.
-/sys/kernel/uids/<uid>/cpu_rt_runtime_us
+Any time not allocated to a realtime group will be used to run normal priority
+tasks (SCHED_OTHER). Any allocated run time not used will also be picked up by
+SCHED_OTHER.
-or
+Let's consider an example: a frame fixed realtime renderer must deliver 25
+frames a second, which yields a period of 0.04s per frame. Now say it will also
+have to play some music and respond to input, leaving it with around 80% CPU
+time dedicated for the graphics. We can then give this group a run time of 0.8
+* 0.04s = 0.032s.
-CONFIG_FAIR_CGROUP_SCHED
+This way the graphics group will have a 0.04s period with a 0.032s run time
+limit. Now if the audio thread needs to refill the DMA buffer every 0.005s, but
+needs only about 3% CPU time to do so, it can do with a 0.03 * 0.005s =
+0.00015s. So this group can be scheduled with a period of 0.005s and a run time
+of 0.00015s.
-/cgroup/<cgroup>/cpu.rt_runtime_us
+The remaining CPU time will be used for user input and other tass. Because
+realtime tasks have explicitly allocated the CPU time they need to perform
+their tasks, buffer underruns in the graphocs or audio can be eliminated.
-[ time is specified in us because the interface is s32; this gives an
- operating range of ~35m to 1us ]
+NOTE: the above example is not fully implemented as of yet (2.6.25). We still
+lack an EDF scheduler to make non-uniform periods usable.
-The period takes values in [ 1, INT_MAX ], runtime in [ -1, INT_MAX - 1 ].
-A runtime of -1 specifies runtime == period, ie. no limit.
+2. The Interface
+================
-New groups get the period from /proc/sys/kernel/sched_rt_period_us and
-a runtime of 0.
-Settings are constrained to:
+2.1 System wide settings
+------------------------
+
+The system wide settings are configured under the /proc virtual file system:
+
+/proc/sys/kernel/sched_rt_period_us:
+ The scheduling period that is equivalent to 100% CPU bandwidth
+
+/proc/sys/kernel/sched_rt_runtime_us:
+ A global limit on how much time realtime scheduling may use. Even without
+ CONFIG_RT_GROUP_SCHED enabled, this will limit time reserved to realtime
+ processes. With CONFIG_RT_GROUP_SCHED it signifies the total bandwidth
+ available to all realtime groups.
+
+ * Time is specified in us because the interface is s32. This gives an
+ operating range from 1us to about 35 minutes.
+ * sched_rt_period_us takes values from 1 to INT_MAX.
+ * sched_rt_runtime_us takes values from -1 to (INT_MAX - 1).
+ * A run time of -1 specifies runtime == period, ie. no limit.
+
+
+2.2 Default behaviour
+---------------------
+
+The default values for sched_rt_period_us (1000000 or 1s) and
+sched_rt_runtime_us (950000 or 0.95s). This gives 0.05s to be used by
+SCHED_OTHER (non-RT tasks). These defaults were chosen so that a run-away
+realtime tasks will not lock up the machine but leave a little time to recover
+it. By setting runtime to -1 you'd get the old behaviour back.
+
+By default all bandwidth is assigned to the root group and new groups get the
+period from /proc/sys/kernel/sched_rt_period_us and a run time of 0. If you
+want to assign bandwidth to another group, reduce the root group's bandwidth
+and assign some or all of the difference to another group.
+
+Realtime group scheduling means you have to assign a portion of total CPU
+bandwidth to the group before it will accept realtime tasks. Therefore you will
+not be able to run realtime tasks as any user other than root until you have
+done that, even if the user has the rights to run processes with realtime
+priority!
+
+
+2.3 Basis for grouping tasks
+----------------------------
+
+There are two compile-time settings for allocating CPU bandwidth. These are
+configured using the "Basis for grouping tasks" multiple choice menu under
+General setup > Group CPU Scheduler:
+
+a. CONFIG_USER_SCHED (aka "Basis for grouping tasks" = "user id")
+
+This lets you use the virtual files under
+"/sys/kernel/uids/<uid>/cpu_rt_runtime_us" to control he CPU time reserved for
+each user .
+
+The other option is:
+
+.o CONFIG_CGROUP_SCHED (aka "Basis for grouping tasks" = "Control groups")
+
+This uses the /cgroup virtual file system and "/cgroup/<cgroup>/cpu.rt_runtime_us"
+to control the CPU time reserved for each control group instead.
+
+For more information on working with control groups, you should read
+Documentation/cgroups.txt as well.
+
+Group settings are checked against the following limits in order to keep the configuration
+schedulable:
\Sum_{i} runtime_{i} / global_period <= global_runtime / global_period
-in order to keep the configuration schedulable.
+For now, this can be simplified to just the following (but see Future plans):
+
+ \Sum_{i} runtime_{i} <= global_runtime
+
+
+3. Future plans
+===============
+
+There is work in progress to make the scheduling period for each group
+("/sys/kernel/uids/<uid>/cpu_rt_period_us" or
+"/cgroup/<cgroup>/cpu.rt_period_us" respectively) configurable as well.
+
+The constraint on the period is that a subgroup must have a smaller or
+equal period to its parent. But realistically its not very useful _yet_
+as its prone to starvation without deadline scheduling.
+
+Consider two sibling groups A and B; both have 50% bandwidth, but A's
+period is twice the length of B's.
+
+* group A: period=100000us, runtime=10000us
+ - this runs for 0.01s once every 0.1s
+
+* group B: period= 50000us, runtime=10000us
+ - this runs for 0.01s twice every 0.1s (or once every 0.05 sec).
+
+This means that currently a while (1) loop in A will run for the full period of
+B and can starve B's tasks (assuming they are of lower priority) for a whole
+period.
+
+The next project will be SCHED_EDF (Earliest Deadline First scheduling) to bring
+full deadline scheduling to the linux kernel. Deadline scheduling the above
+groups and treating end of the period as a deadline will ensure that they both
+get their allocated time.
+
+Implementing SCHED_EDF might take a while to complete. Priority Inheritance is
+the biggest challenge as the current linux PI infrastructure is geared towards
+the limited static priority levels 0-139. With deadline scheduling you need to
+do deadline inheritance (since priority is inversely proportional to the
+deadline delta (deadline - now).
+
+This means the whole PI machinery will have to be reworked - and that is one of
+the most complex pieces of code we have.

- to be out of date, which will cause drivers/net/foo.c to be recompiled.
-
- Most kernel sources, perhaps 80% of them, have at least one CONFIG_*
- dependency somewhere. So changing _any_ CONFIG_* setting requires
- almost _all_ of the kernel to be recompiled.
-
-Here is the solution:
-
- We've made the dependency generator, mkdep.c, smarter. Instead of
- generating this dependency:
-
- drivers/net/foo.c: include/linux/config.h
-
- It now generates these dependencies:
-
- drivers/net/foo.c: \
- include/config/foo/autofrob.h \
- include/config/foo/model/two.h
-
- So drivers/net/foo.c depends only on the CONFIG_* lines that
- it actually uses.
-
- A new program, split-include.c, runs at the beginning of
- compilation (make bzImage or make zImage). split-include reads
- include/linux/autoconf.h and updates the include/config/ tree,
- writing one file per option. It updates only the files for options
- that have changed.
-
-Flag Dependencies
-
- Martin Von Loewis contributed another feature to this patch:
- 'flag dependencies'. The idea is that a .o file depends on
- the compilation flags used to build it. The file foo.o has
- its flags stored in .flags.foo.o.
-
- Suppose the user changes the foo driver from resident to modular.
- 'make' will notice that the current foo.o was not compiled with
- -DMODULE and will recompile foo.c.
-
- All .o files made from C source have flag dependencies. So do .o
- files made with ld, and .a files made with ar. However, .o files
- made from assembly source do not have flag dependencies (nobody
- needs this yet, but it would be good to fix).
-
-Per-source-file Flags
-
- Flag dependencies also work with per-source-file flags.
- You can specify compilation flags for individual source files
- like this:
-
- CFLAGS_foo.o = -DSPECIAL_FOO_DEFINE
-
- This helps clean up drivers/net/Makefile, drivers/scsi/Makefile,
- and several other Makefiles.
-
-Credit
-
- Werner Almesberger had the original idea and wrote the first
- version of this patch.
-
- Michael Chastain picked it up and continued development. He is
- now the principal author and maintainer. Please report any bugs
- to him.
-
- Martin von Loewis wrote flag dependencies, with some modifications
- by Michael Chastain.
-
- Thanks to all of the beta testers.

+What is anchor?
+===============
+
+A USB driver needs to support some callbacks requiring
+a driver to cease all IO to an interface. To do so, a
+driver has to keep track of the URBs it has submitted
+to know they've all completed or to call usb_kill_urb
+for them. The anchor is a data structure takes care of
+keeping track of URBs and provides methods to deal with
+multiple URBs.
+
+Allocation and Initialisation
+=============================
+
+There's no API to allocate an anchor. It is simply declared
+as struct usb_anchor. init_usb_anchor() must be called to
+initialise the data structure.
+
+Deallocation
+============
+
+Once it has no more URBs associated with it, the anchor can be
+freed with normal memory management operations.
+
+Association and disassociation of URBs with anchors
+===================================================
+
+An association of URBs to an anchor is made by an explicit
+call to usb_anchor_urb(). The association is maintained until
+an URB is finished by (successfull) completion. Thus disassociation
+is automatic. A function is provided to forcibly finish (kill)
+all URBs associated with an anchor.
+Furthermore, disassociation can be made with usb_unanchor_urb()
+
+Operations on multitudes of URBs
+================================
+
+usb_kill_anchored_urbs()
+------------------------
+
+This function kills all URBs associated with an anchor. The URBs
+are called in the reverse temporal order they were submitted.
+This way no data can be reordered.
+
+usb_wait_anchor_empty_timeout()
+-------------------------------
+
+This function waits for all URBs associated with an anchor to finish
+or a timeout, whichever comes first. Its return value will tell you
+whether the timeout was reached.

+What callbacks will usbcore do?
+===============================
+
+Usbcore will call into a driver through callbacks defined in the driver
+structure and through the completion handler of URBs a driver submits.
+Only the former are in the scope of this document. These two kinds of
+callbacks are completely independent of each other. Information on the
+completion callback can be found in Documentation/usb/URB.txt.
+
+The callbacks defined in the driver structure are:
+
+1. Hotplugging callbacks:
+
+ * @probe: Called to see if the driver is willing to manage a particular
+ * interface on a device.
+ * @disconnect: Called when the interface is no longer accessible, usually
+ * because its device has been (or is being) disconnected or the
+ * driver module is being unloaded.
+
+2. Odd backdoor through usbfs:
+
+ * @ioctl: Used for drivers that want to talk to userspace through
+ * the "usbfs" filesystem. This lets devices provide ways to
+ * expose information to user space regardless of where they
+ * do (or don't) show up otherwise in the filesystem.
+
+3. Power management (PM) callbacks:
+
+ * @suspend: Called when the device is going to be suspended.
+ * @resume: Called when the device is being resumed.
+ * @reset_resume: Called when the suspended device has been reset instead
+ * of being resumed.
+
+4. Device level operations:
+
+ * @pre_reset: Called when the device is about to be reset.
+ * @post_reset: Called after the device has been reset
+
+The ioctl interface (2) should be used only if you have a very good
+reason. Sysfs is preferred these days. The PM callbacks are covered
+separately in Documentation/usb/power-management.txt.
+
+Calling conventions
+===================
+
+All callbacks are mutually exclusive. There's no need for locking
+against other USB callbacks. All callbacks are called from a task
+context. You may sleep. However, it is important that all sleeps have a
+small fixed upper limit in time. In particular you must not call out to
+user space and await results.
+
+Hotplugging callbacks
+=====================
+
+These callbacks are intended to associate and disassociate a driver with
+an interface. A driver's bond to an interface is exclusive.
+
+The probe() callback
+--------------------
+
+int (*probe) (struct usb_interface *intf,
+ const struct usb_device_id *id);
+
+Accept or decline an interface. If you accept the device return 0,
+otherwise -ENODEV or -ENXIO. Other error codes should be used only if a
+genuine error occurred during initialisation which prevented a driver
+from accepting a device that would else have been accepted.
+You are strongly encouraged to use usbcore'sfacility,
+usb_set_intfdata(), to associate a data structure with an interface, so
+that you know which internal state and identity you associate with a
+particular interface. The device will not be suspended and you may do IO
+to the interface you are called for and endpoint 0 of the device. Device
+initialisation that doesn't take too long is a good idea here.
+
+The disconnect() callback
+-------------------------
+
+void (*disconnect) (struct usb_interface *intf);
+
+This callback is a signal to break any connection with an interface.
+You are not allowed any IO to a device after returning from this
+callback. You also may not do any other operation that may interfere
+with another driver bound the interface, eg. a power management
+operation.
+If you are called due to a physical disconnection, all your URBs will be
+killed by usbcore. Note that in this case disconnect will be called some
+time after the physical disconnection. Thus your driver must be prepared
+to deal with failing IO even prior to the callback.
+
+Device level callbacks
+======================
+
+pre_reset
+---------
+
+int (*pre_reset)(struct usb_interface *intf);
+
+Another driver or user space is triggering a reset on the device which
+contains the interface passed as an argument. Cease IO and save any
+device state you need to restore.
+
+If you need to allocate memory here, use GFP_NOIO or GFP_ATOMIC, if you
+are in atomic context.
+
+post_reset
+----------
+
+int (*post_reset)(struct usb_interface *intf);
+
+The reset has completed. Restore any saved device state and begin
+using the device again.
+
+If you need to allocate memory here, use GFP_NOIO or GFP_ATOMIC, if you
+are in atomic context.
+
+Call sequences
+==============
+
+No callbacks other than probe will be invoked for an interface
+that isn't bound to your driver.
+
+Probe will never be called for an interface bound to a driver.
+Hence following a successful probe, disconnect will be called
+before there is another probe for the same interface.
+
+Once your driver is bound to an interface, disconnect can be
+called at any time except in between pre_reset and post_reset.
+pre_reset is always followed by post_reset, even if the reset
+failed or the device has been unplugged.
+
+suspend is always followed by one of: resume, reset_resume, or
+disconnect.

Components of Memory Policies
- A Linux memory policy is a tuple consisting of a "mode" and an optional set
- of nodes. The mode determine the behavior of the policy, while the
- optional set of nodes can be viewed as the arguments to the behavior.
+ A Linux memory policy consists of a "mode", optional mode flags, and an
+ optional set of nodes. The mode determines the behavior of the policy,
+ the optional mode flags determine the behavior of the mode, and the
+ optional set of nodes can be viewed as the arguments to the policy
+ behavior.
Internally, memory policies are implemented by a reference counted
structure, struct mempolicy. Details of this structure will be discussed
in context, below, as required to explain the behavior.
- Note: in some functions AND in the struct mempolicy itself, the mode
- is called "policy". However, to avoid confusion with the policy tuple,
- this document will continue to use the term "mode".
-
Linux memory policy supports the following 4 behavioral modes:
- Default Mode--MPOL_DEFAULT: The behavior specified by this mode is
- context or scope dependent.
+ Default Mode--MPOL_DEFAULT: This mode is only used in the memory
+ policy APIs. Internally, MPOL_DEFAULT is converted to the NULL
+ memory policy in all policy scopes. Any existing non-default policy
+ will simply be removed when MPOL_DEFAULT is specified. As a result,
+ MPOL_DEFAULT means "fall back to the next most specific policy scope."
- As mentioned in the Policy Scope section above, during normal
- system operation, the System Default Policy is hard coded to
- contain the Default mode.
+ For example, a NULL or default task policy will fall back to the
+ system default policy. A NULL or default vma policy will fall
+ back to the task policy.
- In this context, default mode means "local" allocation--that is
- attempt to allocate the page from the node associated with the cpu
- where the fault occurs. If the "local" node has no memory, or the
- node's memory can be exhausted [no free pages available], local
- allocation will "fallback to"--attempt to allocate pages from--
- "nearby" nodes, in order of increasing "distance".
+ When specified in one of the memory policy APIs, the Default mode
+ does not use the optional set of nodes.
- Implementation detail -- subject to change: "Fallback" uses
- a per node list of sibling nodes--called zonelists--built at
- boot time, or when nodes or memory are added or removed from
- the system [memory hotplug]. These per node zonelist are
- constructed with nodes in order of increasing distance based
- on information provided by the platform firmware.
-
- When a task/process policy or a shared policy contains the Default
- mode, this also means "local allocation", as described above.
-
- In the context of a VMA, Default mode means "fall back to task
- policy"--which may or may not specify Default mode. Thus, Default
- mode can not be counted on to mean local allocation when used
- on a non-shared region of the address space. However, see
- MPOL_PREFERRED below.
-
- The Default mode does not use the optional set of nodes.
+ It is an error for the set of nodes specified for this policy to
+ be non-empty.
MPOL_BIND: This mode specifies that memory must come from the
- set of nodes specified by the policy.
-
- The memory policy APIs do not specify an order in which the nodes
- will be searched. However, unlike "local allocation", the Bind
- policy does not consider the distance between the nodes. Rather,
- allocations will fallback to the nodes specified by the policy in
- order of numeric node id. Like everything in Linux, this is subject
- to change.
+ set of nodes specified by the policy. Memory will be allocated from
+ the node in the set with sufficient free memory that is closest to
+ the node where the allocation takes place.
MPOL_PREFERRED: This mode specifies that the allocation should be
attempted from the single node specified in the policy. If that
- allocation fails, the kernel will search other nodes, exactly as
- it would for a local allocation that started at the preferred node
- in increasing distance from the preferred node. "Local" allocation

containing the cpu where the allocation takes place.
Internally, the Preferred policy uses a single node--the
- preferred_node member of struct mempolicy. A "distinguished
- value of this preferred_node, currently '-1', is interpreted
- as "the node containing the cpu where the allocation takes
- place"--local allocation. This is the way to specify

+ policy can be viewed as a Preferred policy that starts at the node
+ containing the cpu where the allocation takes place.
+
+ It is possible for the user to specify that local allocation is
+ always preferred by passing an empty nodemask with this mode.
+ If an empty nodemask is passed, the policy cannot use the

the temporary interleaved system default policy works in this
mode.
+ Linux memory policy supports the following optional mode flags:
+
+ MPOL_F_STATIC_NODES: This flag specifies that the nodemask passed by
+ the user should not be remapped if the task or VMA's set of allowed
+ nodes changes after the memory policy has been defined.
+
+ Without this flag, anytime a mempolicy is rebound because of a
+ change in the set of allowed nodes, the node (Preferred) or
+ nodemask (Bind, Interleave) is remapped to the new set of
+ allowed nodes. This may result in nodes being used that were
+ previously undesired.
+
+ With this flag, if the user-specified nodes overlap with the
+ nodes allowed by the task's cpuset, then the memory policy is
+ applied to their intersection. If the two sets of nodes do not
+ overlap, the Default policy is used.
+
+ For example, consider a task that is attached to a cpuset with
+ mems 1-3 that sets an Interleave policy over the same set. If
+ the cpuset's mems change to 3-5, the Interleave will now occur
+ over nodes 3, 4, and 5. With this flag, however, since only node
+ 3 is allowed from the user's nodemask, the "interleave" only
+ occurs over that node. If no nodes from the user's nodemask are
+ now allowed, the Default behavior is used.
+
+ MPOL_F_STATIC_NODES cannot be combined with the
+ MPOL_F_RELATIVE_NODES flag. It also cannot be used for
+ MPOL_PREFERRED policies that were created with an empty nodemask
+ (local allocation).
+
+ MPOL_F_RELATIVE_NODES: This flag specifies that the nodemask passed
+ by the user will be mapped relative to the set of the task or VMA's
+ set of allowed nodes. The kernel stores the user-passed nodemask,
+ and if the allowed nodes changes, then that original nodemask will
+ be remapped relative to the new set of allowed nodes.
+
+ Without this flag (and without MPOL_F_STATIC_NODES), anytime a
+ mempolicy is rebound because of a change in the set of allowed
+ nodes, the node (Preferred) or nodemask (Bind, Interleave) is
+ remapped to the new set of allowed nodes. That remap may not
+ preserve the relative nature of the user's passed nodemask to its
+ set of allowed nodes upon successive rebinds: a nodemask of
+ 1,3,5 may be remapped to 7-9 and then to 1-3 if the set of
+ allowed nodes is restored to its original state.
+
+ With this flag, the remap is done so that the node numbers from
+ the user's passed nodemask are relative to the set of allowed
+ nodes. In other words, if nodes 0, 2, and 4 are set in the user's
+ nodemask, the policy will be effected over the first (and in the
+ Bind or Interleave case, the third and fifth) nodes in the set of
+ allowed nodes. The nodemask passed by the user represents nodes
+ relative to task or VMA's set of allowed nodes.
+
+ If the user's nodemask includes nodes that are outside the range
+ of the new set of allowed nodes (for example, node 5 is set in
+ the user's nodemask when the set of allowed nodes is only 0-3),
+ then the remap wraps around to the beginning of the nodemask and,
+ if not already set, sets the node in the mempolicy nodemask.
+
+ For example, consider a task that is attached to a cpuset with
+ mems 2-5 that sets an Interleave policy over the same set with
+ MPOL_F_RELATIVE_NODES. If the cpuset's mems change to 3-7, the
+ interleave now occurs over nodes 3,5-6. If the cpuset's mems
+ then change to 0,2-3,5, then the interleave occurs over nodes
+ 0,3,5.
+
+ Thanks to the consistent remapping, applications preparing
+ nodemasks to specify memory policies using this flag should
+ disregard their current, actual cpuset imposed memory placement
+ and prepare the nodemask as if they were always located on
+ memory nodes 0 to N-1, where N is the number of memory nodes the
+ policy is intended to manage. Let the kernel then remap to the
+ set of memory nodes allowed by the task's cpuset, as that may
+ change over time.
+
+ MPOL_F_RELATIVE_NODES cannot be combined with the
+ MPOL_F_STATIC_NODES flag. It also cannot be used for
+ MPOL_PREFERRED policies that were created with an empty nodemask
+ (local allocation).
+
+MEMORY POLICY REFERENCE COUNTING
+
+To resolve use/free races, struct mempolicy contains an atomic reference
+count field. Internal interfaces, mpol_get()/mpol_put() increment and
+decrement this reference count, respectively. mpol_put() will only free
+the structure back to the mempolicy kmem cache when the reference count
+goes to zero.
+
+When a new memory policy is allocated, it's reference count is initialized
+to '1', representing the reference held by the task that is installing the
+new policy. When a pointer to a memory policy structure is stored in another
+structure, another reference is added, as the task's reference will be dropped
+on completion of the policy installation.
+
+During run-time "usage" of the policy, we attempt to minimize atomic operations
+on the reference count, as this can lead to cache lines bouncing between cpus
+and NUMA nodes. "Usage" here means one of the following:
+
+1) querying of the policy, either by the task itself [using the get_mempolicy()
+ API discussed below] or by another task using the /proc/<pid>/numa_maps
+ interface.
+
+2) examination of the policy to determine the policy mode and associated node
+ or node lists, if any, for page allocation. This is considered a "hot
+ path". Note that for MPOL_BIND, the "usage" extends across the entire
+ allocation process, which may sleep during page reclaimation, because the
+ BIND policy nodemask is used, by reference, to filter ineligible nodes.
+
+We can avoid taking an extra reference during the usages listed above as
+follows:
+
+1) we never need to get/free the system default policy as this is never
+ changed nor freed, once the system is up and running.
+
+2) for querying the policy, we do not need to take an extra reference on the
+ target task's task policy nor vma policies because we always acquire the
+ task's mm's mmap_sem for read during the query. The set_mempolicy() and
+ mbind() APIs [see below] always acquire the mmap_sem for write when
+ installing or replacing task or vma policies. Thus, there is no possibility
+ of a task or thread freeing a policy while another task or thread is
+ querying it.
+
+3) Page allocation usage of task or vma policy occurs in the fault path where
+ we hold them mmap_sem for read. Again, because replacing the task or vma
+ policy requires that the mmap_sem be held for write, the policy can't be
+ freed out from under us while we're using it for page allocation.
+
+4) Shared policies require special consideration. One task can replace a
+ shared memory policy while another task, with a distinct mmap_sem, is
+ querying or allocating a page based on the policy. To resolve this
+ potential race, the shared policy infrastructure adds an extra reference
+ to the shared policy during lookup while holding a spin lock on the shared
+ policy management structure. This requires that we drop this extra
+ reference when we're finished "using" the policy. We must drop the
+ extra reference on shared policies in the same query/allocation paths
+ used for non-shared policies. For this reason, shared policies are marked
+ as such, and the extra reference is dropped "conditionally"--i.e., only
+ for shared policies.
+
+ Because of this extra reference counting, and because we must lookup
+ shared policies in a tree structure under spinlock, shared policies are
+ more expensive to use in the page allocation path. This is expecially
+ true for shared policies on shared memory regions shared by tasks running
+ on different NUMA nodes. This extra overhead can be avoided by always
+ falling back to task or system default policy for shared memory regions,
+ or by prefaulting the entire shared memory region into memory and locking
+ it down. However, this might not be appropriate for all applications.

Memory policies work within cpusets as described above. For memory policies
that require a node or set of nodes, the nodes are restricted to the set of
nodes whose memories are allowed by the cpuset constraints. If the nodemask
-specified for the policy contains nodes that are not allowed by the cpuset, or
-the intersection of the set of nodes specified for the policy and the set of
-nodes with memory is the empty set, the policy is considered invalid
-and cannot be installed.

+specified for the policy and the set of nodes with memory is used. If the
+result is the empty set, the policy is considered invalid and cannot be
+installed. If MPOL_F_RELATIVE_NODES is used, the policy's nodes are mapped
+onto and folded into the task's set of allowed nodes as previously described.
-The interaction of memory policies and cpusets can be problematic for a
-couple of reasons:
-
-1) the memory policy APIs take physical node id's as arguments. As mentioned
- above, it is illegal to specify nodes that are not allowed in the cpuset.
- The application must query the allowed nodes using the get_mempolicy()
- API with the MPOL_F_MEMS_ALLOWED flag to determine the allowed nodes and
- restrict itself to those nodes. However, the resources available to a
- cpuset can be changed by the system administrator, or a workload manager
- application, at any time. So, a task may still get errors attempting to
- specify policy nodes, and must query the allowed memories again.
-
-2) when tasks in two cpusets share access to a memory region, such as shared
- memory segments created by shmget() of mmap() with the MAP_ANONYMOUS and
- MAP_SHARED flags, and any of the tasks install shared policy on the region,
- only nodes whose memories are allowed in both cpusets may be used in the
- policies. Obtaining this information requires "stepping outside" the
- memory policy APIs to use the cpuset information and requires that one
- know in what cpusets other task might be attaching to the shared region.
- Furthermore, if the cpusets' allowed memory sets are disjoint, "local"
- allocation is the only valid policy.

- * The Orion has fully programable address map. There's a separate address

- * Gigabit Ethernet, DMA/XOR engines, etc. Each interface has its own
- * address decode windows that allow it to access any of the Orion resources.
- *
- * CPU address decoding --
- * Linux assumes that it is the boot loader that already setup the access to
- * DDR and internal registers.
- * Setup access to PCI and PCI-E IO/MEM space is issued by core.c.
- * Setup access to various devices located on the device bus interface (e.g.
- * flashes, RTC, etc) should be issued by machine-setup.c according to
- * specific board population (by using orion_setup_cpu_win()).
- *
- * Non-CPU Masters address decoding --
- * Unlike the CPU, we setup the access from Orion's master interfaces to DDR
- * banks only (the typical use case).
- * Setup access for each master to DDR is issued by common.c.
- *
- * Note: although orion_setbits() and orion_clrbits() are not atomic
- * no locking is necessary here since code in this file is only called
- * at boot time when there is no concurrency issues.

+ * Setup access to PCI and PCI-E IO/MEM space is issued by this file.
+ * Setup access to various devices located on the device bus interface (e.g.
+ * flashes, RTC, etc) should be issued by machine-setup.c according to

+ *
+ * Non-CPU Masters address decoding --
+ * Unlike the CPU, we setup the access from Orion's master interfaces to DDR
+ * banks only (the typical use case).
+ * Setup access for each master to DDR is issued by common.c.
+ *
+ * Note: although orion_setbits() and orion_clrbits() are not atomic
+ * no locking is necessary here since code in this file is only called

+ * This file defines the interruption vector table used by the CPU.
+ * It does not include one entry per possible cause of interruption.
+ *
+ * The first 20 entries of the table contain 64 bundles each while the
+ * remaining 48 entries contain only 16 bundles each.
+ *
+ * The 64 bundles are used to allow inlining the whole handler for
+ * critical
+ * interruptions like TLB misses.
+ *
+ * For each entry, the comment is as follows:
+ *
+ * // 0x1c00 Entry 7 (size 64 bundles) Data Key Miss
+ * (12,51)
+ * entry offset ----/ / / /
+ * /
+ * entry number ---------/ / /
+ * /
+ * size of the entry -------------/ /
+ * /
+ * vector name -------------------------------------/
+ * /
+ * interruptions triggering this vector
+ * ----------------------/
+ *
+ * The table is 32KB in size and must be aligned on 32KB
+ * boundary.
+ * (The CPU ignores the 15 lower bits of the address)
+ *
+ * Table is based upon EAS2.6 (Oct 1999)

- * Cross Partition Communication (XPC) support - standard version.
- *
- * XPC provides a message passing capability that crosses partition
- * boundaries. This module is made up of two parts:
- *
- * partition This part detects the presence/absence of other
- * partitions. It provides a heartbeat and monitors
- * the heartbeats of other partitions.
- *
- * channel This part manages the channels and sends/receives
- * messages across them to/from other partitions.
- *
- * There are a couple of additional functions residing in XP, which
- * provide an interface to XPC for its users.
- *
- *
- * Caveats:
- *
- * . We currently have no way to determine which nasid an IPI came
- * from. Thus, xpc_IPI_send() does a remote AMO write followed by
- * an IPI. The AMO indicates where data is to be pulled from, so
- * after the IPI arrives, the remote partition checks the AMO word.
- * The IPI can actually arrive before the AMO however, so other code
- * must periodically check for this case. Also, remote AMO operations
- * do not reliably time out. Thus we do a remote PIO read solely to
- * know whether the remote partition is down and whether we should
- * stop sending IPIs to it. This remote PIO read operation is set up
- * in a special nofault region so SAL knows to ignore (and cleanup)
- * any errors due to the remote AMO write, PIO read, and/or PIO
- * write operations.
- *
- * If/when new hardware solves this IPI problem, we should abandon
- * the current approach.
- *

- * Xen event channels

- * interface with the rest of the kernel by defining a xen interrupt
- * chip. When an event is recieved, it is mapped to an irq and sent
- * through the normal interrupt processing path.
- *
- * There are four kinds of events which can be mapped to an event
- * channel:
- *
- * 1. Inter-domain notifications. This includes all the virtual
- * device events, since they're driven by front-ends in another domain
- * (typically dom0).
- * 2. VIRQs, typically used for timers. These are per-cpu events.
- * 3. IPIs.
- * 4. Hardware interrupts. Not supported at present.

- are still needed.
-
- 2) Improve/fix IRQ and error handling sequences.
-
- 3) ATAPI support (Marvell claims the 60xx/70xx chips can do it).
-
- 4) Think about TCQ support here, and for libata in general
- with controllers that suppport it via host-queuing hardware
- (a software-only implementation could be a nightmare).
-
- 5) Investigate problems with PCI Message Signalled Interrupts (MSI).
-
- 6) Cache frequently-accessed registers in mv_port_priv to reduce overhead.
-
- 7) Fix/reenable hot plug/unplug (should happen as a side-effect of (2) above).
-
- 8) Develop a low-power-consumption strategy, and implement it.
-
- 9) [Experiment, low priority] See if ATAPI can be supported using
- "unknown FIS" or "vendor-specific FIS" support, or something creative
- like that.
-
- 10) [Experiment, low priority] Investigate interrupt coalescing.
- Quite often, especially with PCI Message Signalled Interrupts (MSI),
- the overhead reduced by interrupt mitigation is quite often not
- worth the latency cost.
-
- 11) [Experiment, Marvell value added] Is it possible to use target
- mode to cross-connect two Linux boxes with Marvell cards? If so,
- creating LibATA target mode support would be very interesting.

+ * and/or memory), so we only need half as many bits to represent the

+ * Cross Partition Communication (XPC) support - standard version.
+ *
+ * XPC provides a message passing capability that crosses partition
+ * boundaries. This module is made up of two parts:
+ *
+ * partition This part detects the presence/absence of other
+ * partitions. It provides a heartbeat and monitors
+ * the heartbeats of other partitions.
+ *
+ * channel This part manages the channels and sends/receives
+ * messages across them to/from other partitions.
+ *
+ * There are a couple of additional functions residing in XP, which
+ * provide an interface to XPC for its users.
+ *
+ *
+ * Caveats:
+ *
+ * . We currently have no way to determine which nasid an IPI came
+ * from. Thus, xpc_IPI_send() does a remote AMO write followed by
+ * an IPI. The AMO indicates where data is to be pulled from, so
+ * after the IPI arrives, the remote partition checks the AMO word.
+ * The IPI can actually arrive before the AMO however, so other code
+ * must periodically check for this case. Also, remote AMO operations
+ * do not reliably time out. Thus we do a remote PIO read solely to
+ * know whether the remote partition is down and whether we should
+ * stop sending IPIs to it. This remote PIO read operation is set up
+ * in a special nofault region so SAL knows to ignore (and cleanup)
+ * any errors due to the remote AMO write, PIO read, and/or PIO
+ * write operations.
+ *
+ * If/when new hardware solves this IPI problem, we should abandon
+ * the current approach.

+ * %UBI_VTBL_AUTORESIZE_FLG flag can be set only for one volume in the volume
+ * table. UBI automatically re-sizes the volume which has this flag and makes
+ * the volume to be of largest possible size. This means that if after the
+ * initialization UBI finds out that there are available physical eraseblocks
+ * present on the device, it automatically appends all of them to the volume
+ * (the physical eraseblocks reserved for bad eraseblocks handling and other
+ * reserved physical eraseblocks are not taken). So, if there is a volume with
+ * the %UBI_VTBL_AUTORESIZE_FLG flag set, the amount of available logical
+ * eraseblocks will be zero after UBI is loaded, because all of them will be
+ * reserved for this volume. Note, the %UBI_VTBL_AUTORESIZE_FLG bit is cleared
+ * after the volume had been initialized.
+ *
+ * The auto-resize feature is useful for device production purposes. For
+ * example, different NAND flash chips may have different amount of initial bad
+ * eraseblocks, depending of particular chip instance. Manufacturers of NAND
+ * chips usually guarantee that the amount of initial bad eraseblocks does not
+ * exceed certain percent, e.g. 2%. When one creates an UBI image which will be
+ * flashed to the end devices in production, he does not know the exact amount
+ * of good physical eraseblocks the NAND chip on the device will have, but this
+ * number is required to calculate the volume sized and put them to the volume
+ * table of the UBI image. In this case, one of the volumes (e.g., the one
+ * which will store the root file system) is marked as "auto-resizable", and
+ * UBI will adjust its size on the first boot if needed.
+ *

+ * @padding1: reserved for future, zeroes
+ * @sqnum: sequence number
+ * @padding2: reserved for future, zeroes
+ * @hdr_crc: volume identifier header CRC checksum
+ *
+ * The @sqnum is the value of the global sequence counter at the time when this
+ * VID header was created. The global sequence counter is incremented each time
+ * UBI writes a new VID header to the flash, i.e. when it maps a logical
+ * eraseblock to a new physical eraseblock. The global sequence counter is an
+ * unsigned 64-bit integer and we assume it never overflows. The @sqnum
+ * (sequence number) is used to distinguish between older and newer versions of
+ * logical eraseblocks.
+ *
+ * There are 2 situations when there may be more then one physical eraseblock
+ * corresponding to the same logical eraseblock, i.e., having the same @vol_id
+ * and @lnum values in the volume identifier header. Suppose we have a logical
+ * eraseblock L and it is mapped to the physical eraseblock P.
+ *
+ * 1. Because UBI may erase physical eraseblocks asynchronously, the following
+ * situation is possible: L is asynchronously erased, so P is scheduled for
+ * erasure, then L is written to,i.e. mapped to another physical eraseblock P1,
+ * so P1 is written to, then an unclean reboot happens. Result - there are 2
+ * physical eraseblocks P and P1 corresponding to the same logical eraseblock
+ * L. But P1 has greater sequence number, so UBI picks P1 when it attaches the
+ * flash.
+ *
+ * 2. From time to time UBI moves logical eraseblocks to other physical
+ * eraseblocks for wear-leveling reasons. If, for example, UBI moves L from P
+ * to P1, and an unclean reboot happens before P is physically erased, there
+ * are two physical eraseblocks P and P1 corresponding to L and UBI has to
+ * select one of them when the flash is attached. The @sqnum field says which
+ * PEB is the original (obviously P will have lower @sqnum) and the copy. But
+ * it is not enough to select the physical eraseblock with the higher sequence
+ * number, because the unclean reboot could have happen in the middle of the
+ * copying process, so the data in P is corrupted. It is also not enough to
+ * just select the physical eraseblock with lower sequence number, because the
+ * data there may be old (consider a case if more data was added to P1 after
+ * the copying). Moreover, the unclean reboot may happen when the erasure of P
+ * was just started, so it result in unstable P, which is "mostly" OK, but
+ * still has unstable bits.
+ *
+ * UBI uses the @copy_flag field to indicate that this logical eraseblock is a
+ * copy. UBI also calculates data CRC when the data is moved and stores it at
+ * the @data_crc field of the copy (P1). So when UBI needs to pick one physical
+ * eraseblock of two (P or P1), the @copy_flag of the newer one (P1) is
+ * examined. If it is cleared, the situation* is simple and the newer one is
+ * picked. If it is set, the data CRC of the copy (P1) is examined. If the CRC
+ * checksum is correct, this physical eraseblock is selected (P1). Otherwise
+ * the older one (P) is selected.
+ *
+ * Note, there is an obsolete @leb_ver field which was used instead of @sqnum
+ * in the past. But it is not used anymore and we keep it in order to be able
+ * to deal with old UBI images. It will be removed at some point.
+ *
+ * There are 2 sorts of volumes in UBI: user volumes and internal volumes.
+ * Internal volumes are not seen from outside and are used for various internal
+ * UBI purposes. In this implementation there is only one internal volume - the
+ * layout volume. Internal volumes are the main mechanism of UBI extensions.
+ * For example, in future one may introduce a journal internal volume. Internal
+ * volumes have their own reserved range of IDs.
+ *
+ * The @compat field is only used for internal volumes and contains the "degree
+ * of their compatibility". It is always zero for user volumes. This field
+ * provides a mechanism to introduce UBI extensions and to be still compatible
+ * with older UBI binaries. For example, if someone introduced a journal in
+ * future, he would probably use %UBI_COMPAT_DELETE compatibility for the
+ * journal volume. And in this case, older UBI binaries, which know nothing
+ * about the journal volume, would just delete this volume and work perfectly
+ * fine. This is similar to what Ext2fs does when it is fed by an Ext3fs image
+ * - it just ignores the Ext3fs journal.
+ *
+ * The @data_crc field contains the CRC checksum of the contents of the logical
+ * eraseblock if this is a static volume. In case of dynamic volumes, it does
+ * not contain the CRC checksum as a rule. The only exception is when the
+ * data of the physical eraseblock was moved by the wear-leveling unit, then
+ * the wear-leveling unit calculates the data CRC and stores it in the
+ * @data_crc field. And of course, the @copy_flag is %in this case.
+ *
+ * The @data_size field is used only for static volumes because UBI has to know
+ * how many bytes of data are stored in this eraseblock. For dynamic volumes,
+ * this field usually contains zero. The only exception is when the data of the
+ * physical eraseblock was moved to another physical eraseblock for
+ * wear-leveling reasons. In this case, UBI calculates CRC checksum of the
+ * contents and uses both @data_crc and @data_size fields. In this case, the
+ * @data_size field contains data size.
+ *
+ * The @used_ebs field is used only for static volumes and indicates how many
+ * eraseblocks the data of the volume takes. For dynamic volumes this field is
+ * not used and always contains zero.
+ *
+ * The @data_pad is calculated when volumes are created using the alignment
+ * parameter. So, effectively, the @data_pad field reduces the size of logical
+ * eraseblocks of this volume. This is very handy when one uses block-oriented
+ * software (say, cramfs) on top of the UBI volume.

* Special thanks to Intel and VIA for providing host controllers to

- *
- * HISTORY:
- *
- * 2004-05-10 Root hub and PCI suspend/resume support; remote wakeup. (db)
- * 2004-02-24 Replace pci_* with generic dma_* API calls (dsaxena@plexity.net)
- * 2003-12-29 Rewritten high speed iso transfer support (by Michal Sojka,
- * <sojkam@centrum.cz>, updates by DB).
- *
- * 2002-11-29 Correct handling for hw async_next register.
- * 2002-08-06 Handling for bulk and interrupt transfers is mostly shared;
- * only scheduling is different, no arbitrary limitations.
- * 2002-07-25 Sanity check PCI reads, mostly for better cardbus support,
- * clean up HC run state handshaking.
- * 2002-05-24 Preliminary FS/LS interrupts, using scheduling shortcuts
- * 2002-05-11 Clear TT errors for FS/LS ctrl/bulk. Fill in some other
- * missing pieces: enabling 64bit dma, handoff from BIOS/SMM.
- * 2002-05-07 Some error path cleanups to report better errors; wmb();
- * use non-CVS version id; better iso bandwidth claim.
- * 2002-04-19 Control/bulk/interrupt submit no longer uses giveback() on
- * errors in submit path. Bugfixes to interrupt scheduling/processing.
- * 2002-03-05 Initial high-speed ISO support; reduce ITD memory; shift
- * more checking to generic hcd framework (db). Make it work with
- * Philips EHCI; reduce PCI traffic; shorten IRQ path (Rory Bolt).
- * 2002-01-14 Minor cleanup; version synch.
- * 2002-01-08 Fix roothub handoff of FS/LS to companion controllers.
- * 2002-01-04 Control/Bulk queuing behaves.
- *
- * 2001-12-12 Initial patch version for Linux 2.5.1 kernel.
- * 2001-June Works with usb-storage and NEC EHCI on 2.4

- * This driver is written to be used with the Hecuba display controller
- * board, and tested with the EInk 800x600 display in 1 bit mode.
- * The interface between Hecuba and the host is TTL based GPIO. The
- * GPIO requirements are 8 writable data lines and 6 lines for control.
- * Only 4 of the controls are actually used here but 6 for future use.
- * The driver requires the IO addresses for data and control GPIO at

- * PC parallel port.
+ * This driver is written to be used with the Hecuba display architecture.
+ * The actual display chip is called Apollo and the interface electronics
+ * it needs is called Hecuba.
*
- * General notes:
- * - User must set hecubafb_enable=1 to enable it
- * - User must set dio_addr=0xIOADDR cio_addr=0xIOADDR c2io_addr=0xIOADDR
+ * It is intended to be architecture independent. A board specific driver
+ * must be used to perform all the physical IO interactions. An example
+ * is provided as n411.c

* This driver is written to be used with the Metronome display controller.
- * It was tested with an E-Ink 800x600 Vizplex EPD on a Gumstix Connex board
- * using the Lyre interface board.
+ * It is intended to be architecture independent. A board specific driver
+ * must be used to perform all the physical IO interactions. An example

*
- * General notes:
- * - User must set metronomefb_enable=1 to enable it.
- * - See Documentation/fb/metronomefb.txt for how metronome works.

+ * Layout is based on skeletonfb.c by James Simmons and Geert Uytterhoeven.
+ *
+ * This driver is written to be used with the Hecuba display controller
+ * board, and tested with the EInk 800x600 display in 1 bit mode.
+ * The interface between Hecuba and the host is TTL based GPIO. The
+ * GPIO requirements are 8 writable data lines and 6 lines for control.
+ * Only 4 of the controls are actually used here but 6 for future use.
+ * The driver requires the IO addresses for data and control GPIO at
+ * load time. It is also possible to use this display with a standard
+ * PC parallel port.
+ *
+ * General notes:
+ * - User must set dio_addr=0xIOADDR cio_addr=0xIOADDR c2io_addr=0xIOADDR

+ Scrub pages before returning them to the system for reuse by

+/*
+ * Xen event channels
+ *
+ * Xen models interrupts with abstract event channels. Because each
+ * domain gets 1024 event channels, but NR_IRQ is not that large, we
+ * must dynamically map irqs<->event channels. The event channels
+ * interface with the rest of the kernel by defining a xen interrupt
+ * chip. When an event is recieved, it is mapped to an irq and sent
+ * through the normal interrupt processing path.
+ *
+ * There are four kinds of events which can be mapped to an event
+ * channel:
+ *
+ * 1. Inter-domain notifications. This includes all the virtual
+ * device events, since they're driven by front-ends in another domain
+ * (typically dom0).
+ * 2. VIRQs, typically used for timers. These are per-cpu events.
+ * 3. IPIs.
+ * 4. Hardware interrupts. Not supported at present.
+ *

- * udf_lookup
- *
- * PURPOSE
- * Look-up the inode for a given name.
- *
- * DESCRIPTION
- * Required - lookup_dentry() will return -ENOTDIR if this routine is not
- * available for a directory. The filesystem is useless if this routine is
- * not available for at least the filesystem's root directory.
- *
- * This routine is passed an incomplete dentry - it must be completed by
- * calling d_add(dentry, inode). If the name does not exist, then the
- * specified inode must be set to null. An error should only be returned
- * when the lookup fails for a reason other than the name not existing.
- * Note that the directory inode semaphore is held during the call.
- *
- * Refer to lookup_dentry() in fs/namei.c
- * lookup_dentry() -> lookup() -> real_lookup() -> .
- *
- * PRE-CONDITIONS
- * dir Pointer to inode of parent directory.
- * dentry Pointer to dentry to complete.
- * nd Pointer to lookup nameidata
- *
- * POST-CONDITIONS
- * <return> Zero on success.
- *
- * HISTORY
- * July 1, 1997 - Andrew E. Mileski
- * Written, tested, and released.

- * udf_set_blocksize

- * PURPOSE

- * DESCRIPTION
- * To allow room for a DMA transfer, it is best to guess big when unsure.
- * This routine picks 2048 bytes as the blocksize when guessing. This
- * should be adequate until devices with larger block sizes become common.
- *
- * Note that the Linux kernel can currently only deal with blocksizes of
- * 512, 1024, 2048, 4096, and 8192 bytes.
- *
- * PRE-CONDITIONS
- * sb Pointer to _locked_ superblock.
- *
- * POST-CONDITIONS
- * sb->s_blocksize Blocksize.
- * sb->s_blocksize_bits log2 of blocksize.
- * <return> 0 Blocksize is valid.
- * <return> 1 Blocksize is invalid.
- *
- * HISTORY
- * July 1, 1997 - Andrew E. Mileski
- * Written, tested, and released.

- * the reserved page
- *
- * SAL reserves one page of memory per partition for XPC. Though a full page
- * in length (16384 bytes), its starting address is not page aligned, but it
- * is cacheline aligned. The reserved page consists of the following:
- *
- * reserved page header
- *
- * The first cacheline of the reserved page contains the header
- * (struct xpc_rsvd_page). Before SAL initialization has completed,
- * SAL has set up the following fields of the reserved page header:
- * SAL_signature, SAL_version, partid, and nasids_size. The other
- * fields are set up by XPC. (xpc_rsvd_page points to the local
- * partition's reserved page.)
- *
- * part_nasids mask
- * mach_nasids mask
- *
- * SAL also sets up two bitmaps (or masks), one that reflects the actual
- * nasids in this partition (part_nasids), and the other that reflects
- * the actual nasids in the entire machine (mach_nasids). We're only
- * interested in the even numbered nasids (which contain the processors
- * and/or memory), so we only need half as many bits to represent the
- * nasids. The part_nasids mask is located starting at the first cacheline
- * following the reserved page header. The mach_nasids mask follows right
- * after the part_nasids mask. The size in bytes of each mask is reflected
- * by the reserved page header field 'nasids_size'. (Local partition's
- * mask pointers are xpc_part_nasids and xpc_mach_nasids.)
- *
- * vars
- * vars part
- *
- * Immediately following the mach_nasids mask are the XPC variables
- * required by other partitions. First are those that are generic to all
- * partitions (vars), followed on the next available cacheline by those
- * which are partition specific (vars part). These are setup by XPC.
- * (Local partition's vars pointers are xpc_vars and xpc_vars_part.)

- * UBI will adjust its size on the first boot if needed.
- *
- * Note, first UBI reserves some amount of physical eraseblocks for bad

- * @padding1: reserved for future, zeroes
- * @sqnum: sequence number
- * @padding2: reserved for future, zeroes
- * @hdr_crc: volume identifier header CRC checksum
- *
- * The @sqnum is the value of the global sequence counter at the time when this
- * VID header was created. The global sequence counter is incremented each time
- * UBI writes a new VID header to the flash, i.e. when it maps a logical
- * eraseblock to a new physical eraseblock. The global sequence counter is an
- * unsigned 64-bit integer and we assume it never overflows. The @sqnum
- * (sequence number) is used to distinguish between older and newer versions of
- * logical eraseblocks.
- *
- * There are 2 situations when there may be more then one physical eraseblock
- * corresponding to the same logical eraseblock, i.e., having the same @vol_id
- * and @lnum values in the volume identifier header. Suppose we have a logical
- * eraseblock L and it is mapped to the physical eraseblock P.
- *
- * 1. Because UBI may erase physical eraseblocks asynchronously, the following
- * situation is possible: L is asynchronously erased, so P is scheduled for
- * erasure, then L is written to,i.e. mapped to another physical eraseblock P1,
- * so P1 is written to, then an unclean reboot happens. Result - there are 2
- * physical eraseblocks P and P1 corresponding to the same logical eraseblock
- * L. But P1 has greater sequence number, so UBI picks P1 when it attaches the
- * flash.
- *
- * 2. From time to time UBI moves logical eraseblocks to other physical
- * eraseblocks for wear-leveling reasons. If, for example, UBI moves L from P
- * to P1, and an unclean reboot happens before P is physically erased, there
- * are two physical eraseblocks P and P1 corresponding to L and UBI has to
- * select one of them when the flash is attached. The @sqnum field says which
- * PEB is the original (obviously P will have lower @sqnum) and the copy. But
- * it is not enough to select the physical eraseblock with the higher sequence
- * number, because the unclean reboot could have happen in the middle of the
- * copying process, so the data in P is corrupted. It is also not enough to
- * just select the physical eraseblock with lower sequence number, because the
- * data there may be old (consider a case if more data was added to P1 after
- * the copying). Moreover, the unclean reboot may happen when the erasure of P
- * was just started, so it result in unstable P, which is "mostly" OK, but
- * still has unstable bits.
- *
- * UBI uses the @copy_flag field to indicate that this logical eraseblock is a
- * copy. UBI also calculates data CRC when the data is moved and stores it at
- * the @data_crc field of the copy (P1). So when UBI needs to pick one physical
- * eraseblock of two (P or P1), the @copy_flag of the newer one (P1) is
- * examined. If it is cleared, the situation* is simple and the newer one is
- * picked. If it is set, the data CRC of the copy (P1) is examined. If the CRC
- * checksum is correct, this physical eraseblock is selected (P1). Otherwise
- * the older one (P) is selected.
- *
- * Note, there is an obsolete @leb_ver field which was used instead of @sqnum
- * in the past. But it is not used anymore and we keep it in order to be able
- * to deal with old UBI images. It will be removed at some point.
- *
- * There are 2 sorts of volumes in UBI: user volumes and internal volumes.
- * Internal volumes are not seen from outside and are used for various internal
- * UBI purposes. In this implementation there is only one internal volume - the
- * layout volume. Internal volumes are the main mechanism of UBI extensions.
- * For example, in future one may introduce a journal internal volume. Internal
- * volumes have their own reserved range of IDs.
- *
- * The @compat field is only used for internal volumes and contains the "degree
- * of their compatibility". It is always zero for user volumes. This field
- * provides a mechanism to introduce UBI extensions and to be still compatible
- * with older UBI binaries. For example, if someone introduced a journal in
- * future, he would probably use %UBI_COMPAT_DELETE compatibility for the
- * journal volume. And in this case, older UBI binaries, which know nothing
- * about the journal volume, would just delete this volume and work perfectly
- * fine. This is similar to what Ext2fs does when it is fed by an Ext3fs image
- * - it just ignores the Ext3fs journal.
- *
- * The @data_crc field contains the CRC checksum of the contents of the logical
- * eraseblock if this is a static volume. In case of dynamic volumes, it does
- * not contain the CRC checksum as a rule. The only exception is when the
- * data of the physical eraseblock was moved by the wear-leveling unit, then
- * the wear-leveling unit calculates the data CRC and stores it in the
- * @data_crc field. And of course, the @copy_flag is %in this case.
- *
- * The @data_size field is used only for static volumes because UBI has to know
- * how many bytes of data are stored in this eraseblock. For dynamic volumes,
- * this field usually contains zero. The only exception is when the data of the
- * physical eraseblock was moved to another physical eraseblock for
- * wear-leveling reasons. In this case, UBI calculates CRC checksum of the
- * contents and uses both @data_crc and @data_size fields. In this case, the
- * @data_size field contains data size.
- *
- * The @used_ebs field is used only for static volumes and indicates how many
- * eraseblocks the data of the volume takes. For dynamic volumes this field is
- * not used and always contains zero.
- *
- * The @data_pad is calculated when volumes are created using the alignment
- * parameter. So, effectively, the @data_pad field reduces the size of logical
- * eraseblocks of this volume. This is very handy when one uses block-oriented
- * software (say, cramfs) on top of the UBI volume.

- * We detect special mappings in one of two ways:

- * 2. If the MFN belongs to a different domain then we will certainly
- * not have MFN in our p2m table. Conversely, if the page is ours,
- * then we'll have p2m(m2p(MFN))==MFN.
- * If we detect a special mapping then it doesn't have a 'struct page'.
- * We force !pfn_valid() by returning an out-of-range pointer.
- *
- * NB. These checks require that, for any MFN that is not in our reservation,
- * there is no PFN such that p2m(PFN) == MFN. Otherwise we can get confused if
- * we are foreign-mapping the MFN, and the other domain as m2p(MFN) == PFN.
- * Yikes! Various places must poke in INVALID_P2M_ENTRY for safety.
- *
- * NB2. When deliberately mapping foreign pages into the p2m table, you *must*
- * use FOREIGN_FRAME(). This will cause pte_pfn() to choke on it, as we
- * require. In all the cases we care about, the FOREIGN_FRAME bit is

+ * @dst: resulting translated bitmap
+ * @orig: original untranslated bitmap
+ * @relmap: bitmap relative to which translated
+ * @bits: number of bits in each of these bitmaps
+ *
+ * Set the n-th bit of @dst iff there exists some m such that the
+ * n-th bit of @relmap is set, the m-th bit of @orig is set, and
+ * the n-th bit of @relmap is also the m-th _set_ bit of @relmap.
+ * (If you understood the previous sentence the first time your
+ * read it, you're overqualified for your current job.)
+ *
+ * In other words, @orig is mapped onto (surjectively) @dst,
+ * using the the map { <n, m> | the n-th bit of @relmap is the
+ * m-th set bit of @relmap }.
+ *
+ * Any set bits in @orig above bit number W, where W is the
+ * weight of (number of set bits in) @relmap are mapped nowhere.
+ * In particular, if for all bits m set in @orig, m >= W, then
+ * @dst will end up empty. In situations where the possibility
+ * of such an empty result is not desired, one way to avoid it is
+ * to use the bitmap_fold() operator, below, to first fold the
+ * @orig bitmap over itself so that all its set bits x are in the
+ * range 0 <= x < W. The bitmap_fold() operator does this by
+ * setting the bit (m % W) in @dst, for each bit (m) set in @orig.
+ *
+ * Example [1] for bitmap_onto():
+ * Let's say @relmap has bits 30-39 set, and @orig has bits
+ * 1, 3, 5, 7, 9 and 11 set. Then on return from this routine,
+ * @dst will have bits 31, 33, 35, 37 and 39 set.
+ *
+ * When bit 0 is set in @orig, it means turn on the bit in
+ * @dst corresponding to whatever is the first bit (if any)
+ * that is turned on in @relmap. Since bit 0 was off in the
+ * above example, we leave off that bit (bit 30) in @dst.
+ *
+ * When bit 1 is set in @orig (as in the above example), it
+ * means turn on the bit in @dst corresponding to whatever
+ * is the second bit that is turned on in @relmap. The second
+ * bit in @relmap that was turned on in the above example was
+ * bit 31, so we turned on bit 31 in @dst.
+ *
+ * Similarly, we turned on bits 33, 35, 37 and 39 in @dst,
+ * because they were the 4th, 6th, 8th and 10th set bits
+ * set in @relmap, and the 4th, 6th, 8th and 10th bits of
+ * @orig (i.e. bits 3, 5, 7 and 9) were also set.
+ *
+ * When bit 11 is set in @orig, it means turn on the bit in
+ * @dst corresponding to whatever is the twelth bit that is
+ * turned on in @relmap. In the above example, there were
+ * only ten bits turned on in @relmap (30..39), so that bit
+ * 11 was set in @orig had no affect on @dst.
+ *
+ * Example [2] for bitmap_fold() + bitmap_onto():
+ * Let's say @relmap has these ten bits set:
+ * 40 41 42 43 45 48 53 61 74 95
+ * (for the curious, that's 40 plus the first ten terms of the
+ * Fibonacci sequence.)
+ *
+ * Further lets say we use the following code, invoking
+ * bitmap_fold() then bitmap_onto, as suggested above to
+ * avoid the possitility of an empty @dst result:
+ *
+ * unsigned long *tmp; // a temporary bitmap's bits
+ *
+ * bitmap_fold(tmp, orig, bitmap_weight(relmap, bits), bits);
+ * bitmap_onto(dst, tmp, relmap, bits);
+ *
+ * Then this table shows what various values of @dst would be, for
+ * various @orig's. I list the zero-based positions of each set bit.
+ * The tmp column shows the intermediate result, as computed by
+ * using bitmap_fold() to fold the @orig bitmap modulo ten
+ * (the weight of @relmap).
+ *
+ * @orig tmp @dst
+ * 0 0 40
+ * 1 1 41
+ * 9 9 95
+ * 10 0 40 (*)
+ * 1 3 5 7 1 3 5 7 41 43 48 61
+ * 0 1 2 3 4 0 1 2 3 4 40 41 42 43 45
+ * 0 9 18 27 0 9 8 7 40 61 74 95
+ * 0 10 20 30 0 40

+ * 78 102 211 1 2 8 41 42 74 (*)
+ *
+ * (*) For these marked lines, if we hadn't first done bitmap_fold()
+ * into tmp, then the @dst result would have been empty.
+ *
+ * If either of @orig or @relmap is empty (no set bits), then @dst
+ * will be returned empty.
+ *
+ * If (as explained above) the only set bits in @orig are in positions

*
- * NOTE! Some mappings do not have "struct pages". A raw PFN mapping
- * will have each page table entry just pointing to a raw page frame
- * number, and as far as the VM layer is concerned, those do not have
- * pages associated with them - even if the PFN might point to memory
- * that otherwise is perfectly fine and has a "struct page".
+ * "Special" mappings do not wish to be associated with a "struct page" (either
+ * it doesn't exist, or it exists but they don't want to touch it). In this
+ * case, NULL is returned here. "Normal" mappings do have a struct page.
*
- * The way we recognize those mappings is through the rules set up
- * by "remap_pfn_range()": the vma will have the VM_PFNMAP bit set,
- * and the vm_pgoff will point to the first PFN mapped: thus every
- * page that is a raw mapping will always honor the rule
+ * There are 2 broad cases. Firstly, an architecture may define a pte_special()
+ * pte bit, in which case this function is trivial. Secondly, an architecture
+ * may not have a spare pte bit, which requires a more complicated scheme,
+ * described below.
+ *
+ * A raw VM_PFNMAP mapping (ie. one that is not COWed) is always considered a
+ * special mapping (even if there are underlying and valid "struct pages").
+ * COWed pages of a VM_PFNMAP are always normal.
+ *
+ * The way we recognize COWed pages within VM_PFNMAP mappings is through the
+ * rules set up by "remap_pfn_range()": the vma will have the VM_PFNMAP bit
+ * set, and the vm_pgoff will point to the first PFN mapped: thus every special
+ * mapping will always honor the rule
*
* pfn_of_page == vma->vm_pgoff + ((addr - vma->vm_start) >> PAGE_SHIFT)
*
- * and if that isn't true, the page has been COW'ed (in which case it
- * _does_ have a "struct page" associated with it even if it is in a
- * VM_PFNMAP range).
+ * And for normal mappings this is false.
+ *
+ * This restricts such mappings to be a linear translation from virtual address
+ * to pfn. To get around this restriction, we allow arbitrary mappings so long
+ * as the vma is not a COW mapping; in that case, we know that all ptes are
+ * special (because none can have been COWed).
+ *
+ *
+ * In order to support COW of arbitrary special mappings, we have VM_MIXEDMAP.
+ *
+ * VM_MIXEDMAP mappings can likewise contain memory with or without "struct
+ * page" backing, however the difference is that _all_ pages with a struct
+ * page (that is, those where pfn_valid is true) are refcounted and considered
+ * normal pages by the VM. The disadvantage is that pages are refcounted
+ * (which can be slower and simply not an option for some PFNMAP users). The
+ * advantage is that we don't have to follow the strict linearity rule of
+ * PFNMAP mappings in order to support COWable mappings.

+ If you don't have a sound card in your computer, you can include a
+ driver for the PC speaker which allows it to act like a primitive
+ sound card.
+ This driver also replaces the pcspkr driver for beeps.
+
+ You can compile this as a module which will be called snd-pcsp.
+
+ You don't need this driver if you only want your pc-speaker to beep.
+ You don't need this driver if you have a tablet piezo beeper
+ in your PC instead of the real speaker.
+
+ It should not hurt to say Y or M here in all other cases.

+ * This fact is applied in the driver, allowing to modify PCM stream rate

+ *
+ * Juli uses the remaining three stereo-channels of its DAC to optionally
+ * monitor analog input, digital input, and digital output. The corresponding
+ * I2S signals are routed by Xilinx, controlled by GPIOs.
