+Description: The /sys/dev tree provides a method to look up the sysfs
+ path for a device using the information returned from
+ stat(2). There are two directories, 'block' and 'char',
+ beneath /sys/dev containing symbolic links with names of
+ the form "<major>:<minor>". These links point to the
+ corresponding sysfs path for the given device.
+
+ Example:
+ $ readlink /sys/dev/block/8:32
+ ../../block/sdc
+
+ Entries in /sys/dev/char and /sys/dev/block will be
+ dynamically created and destroyed as devices enter and
+ leave the system.

+===============================================================
+
+
+A generic digital 24-port PCI GPIO card can be built out of an ordinary
+Brooktree bt848, bt849, bt878 or bt879 based analog TV tuner card. The
+Brooktree chip is used in old analog Hauppauge WinTV PCI cards. You can easily
+find them used for low prices on the net.
+
+The bt8xx chip does have 24 digital GPIO ports.
+These ports are accessible via 24 pins on the SMD chip package.
+
+
+==============================================
+== How to physically access the GPIO pins ==
+==============================================
+
+The are several ways to access these pins. One might unsolder the whole chip
+and put it on a custom PCI board, or one might only unsolder each individual
+GPIO pin and solder that to some tiny wire. As the chip package really is tiny
+there are some advanced soldering skills needed in any case.
+
+The physical pinouts are drawn in the following ASCII art.

+SH7760/SH7763 integrated LCDC Framebuffer driver
+================================================
+
+0. Overwiew
+-----------
+The SH7760/SH7763 have an integrated LCD Display controller (LCDC) which
+supports (in theory) resolutions ranging from 1x1 to 1024x1024,
+with color depths ranging from 1 to 16 bits, on STN, DSTN and TFT Panels.
+
+Caveats:
+* Framebuffer memory must be a large chunk allocated at the top
+ of Area3 (HW requirement). Because of this requirement you should NOT
+ make the driver a module since at runtime it may become impossible to
+ get a large enough contiguous chunk of memory.
+
+* The driver does not support changing resolution while loaded
+ (displays aren't hotpluggable anyway)
+
+* Heavy flickering may be observed
+ a) if you're using 15/16bit color modes at >= 640x480 px resolutions,
+ b) during PCMCIA (or any other slow bus) activity.
+
+* Rotation works only 90degress clockwise, and only if horizontal
+ resolution is <= 320 pixels.

+1. Platform setup
+-----------------
+SH7760:
+ Video data is fetched via the DMABRG DMA engine, so you have to
+ configure the SH DMAC for DMABRG mode (write 0x94808080 to the
+ DMARSRA register somewhere at boot).
+
+ PFC registers PCCR and PCDR must be set to peripheral mode.
+ (write zeros to both).
+
+The driver does NOT do the above for you since board setup is, well, job
+of the board setup code.
+
+2. Panel definitions
+--------------------
+The LCDC must explicitly be told about the type of LCD panel
+attached. Data must be wrapped in a "struct sh7760fb_platdata" and
+passed to the driver as platform_data.
+
+Suggest you take a closer look at the SH7760 Manual, Section 30.

+Optimized MPEG Filesystem (OMFS)
+
+Overview
+========
+
+OMFS is a filesystem created by SonicBlue for use in the ReplayTV DVR
+and Rio Karma MP3 player. The filesystem is extent-based, utilizing
+block sizes from 2k to 8k, with hash-based directories. This
+filesystem driver may be used to read and write disks from these
+devices.
+
+Note, it is not recommended that this FS be used in place of a general
+filesystem for your own streaming media device. Native Linux filesystems
+will likely perform better.
+
+More information is available at:
+
+ http://linux-karma.sf.net/
+
+Various utilities, including mkomfs and omfsck, are included with
+omfsprogs, available at:
+
+ http://bobcopeland.com/karma/
+
+Instructions are included in its README.
+
+Options
+=======
+
+OMFS supports the following mount-time options:
+
+ uid=n - make all files owned by specified user
+ gid=n - make all files owned by specified group
+ umask=xxx - set permission umask to xxx
+ fmask=xxx - set umask to xxx for files
+ dmask=xxx - set umask to xxx for directories
+
+Disk format
+===========
+
+OMFS discriminates between "sysblocks" and normal data blocks. The sysblock
+group consists of super block information, file metadata, directory structures,
+and extents. Each sysblock has a header containing CRCs of the entire
+sysblock, and may be mirrored in successive blocks on the disk. A sysblock may
+have a smaller size than a data block, but since they are both addressed by the
+same 64-bit block number, any remaining space in the smaller sysblock is
+unused.
+
+Sysblock header information:
+
+struct omfs_header {
+ __be64 h_self; /* FS block where this is located */
+ __be32 h_body_size; /* size of useful data after header */
+ __be16 h_crc; /* crc-ccitt of body_size bytes */
+ char h_fill1[2];
+ u8 h_version; /* version, always 1 */
+ char h_type; /* OMFS_INODE_X */
+ u8 h_magic; /* OMFS_IMAGIC */
+ u8 h_check_xor; /* XOR of header bytes before this */
+ __be32 h_fill2;
+};
+
+Files and directories are both represented by omfs_inode:
+
+struct omfs_inode {
+ struct omfs_header i_head; /* header */
+ __be64 i_parent; /* parent containing this inode */
+ __be64 i_sibling; /* next inode in hash bucket */
+ __be64 i_ctime; /* ctime, in milliseconds */
+ char i_fill1[35];
+ char i_type; /* OMFS_[DIR,FILE] */
+ __be32 i_fill2;
+ char i_fill3[64];
+ char i_name[OMFS_NAMELEN]; /* filename */
+ __be64 i_size; /* size of file, in bytes */
+};
+
+Directories in OMFS are implemented as a large hash table. Filenames are
+hashed then prepended into the bucket list beginning at OMFS_DIR_START.
+Lookup requires hashing the filename, then seeking across i_sibling pointers
+until a match is found on i_name. Empty buckets are represented by block
+pointers with all-1s (~0).
+
+A file is an omfs_inode structure followed by an extent table beginning at
+OMFS_EXTENT_START:
+
+struct omfs_extent_entry {
+ __be64 e_cluster; /* start location of a set of blocks */
+ __be64 e_blocks; /* number of blocks after e_cluster */
+};
+
+struct omfs_extent {
+ __be64 e_next; /* next extent table location */
+ __be32 e_extent_count; /* total # extents in this table */
+ __be32 e_fill;
+ struct omfs_extent_entry e_entry; /* start of extent entries */
+};
+
+Each extent holds the block offset followed by number of blocks allocated to
+the extent. The final extent in each table is a terminator with e_cluster
+being ~0 and e_blocks being ones'-complement of the total number of blocks
+in the table.
+
+If this table overflows, a continuation inode is written and pointed to by
+e_next. These have a header but lack the rest of the inode structure.

+once all the necessary resources are available, and remove them later when
+the GPIO controller device becomes unavailable.
+
+
+Sysfs Interface for Userspace (OPTIONAL)
+========================================
+Platforms which use the "gpiolib" implementors framework may choose to
+configure a sysfs user interface to GPIOs. This is different from the
+debugfs interface, since it provides control over GPIO direction and
+value instead of just showing a gpio state summary. Plus, it could be
+present on production systems without debugging support.
+
+Given approprate hardware documentation for the system, userspace could
+know for example that GPIO #23 controls the write protect line used to
+protect boot loader segments in flash memory. System upgrade procedures
+may need to temporarily remove that protection, first importing a GPIO,
+then changing its output state, then updating the code before re-enabling
+the write protection. In normal use, GPIO #23 would never be touched,
+and the kernel would have no need to know about it.
+
+Again depending on appropriate hardware documentation, on some systems
+userspace GPIO can be used to determine system configuration data that
+standard kernels won't know about. And for some tasks, simple userspace
+GPIO drivers could be all that the system really needs.
+
+Note that standard kernel drivers exist for common "LEDs and Buttons"
+GPIO tasks: "leds-gpio" and "gpio_keys", respectively. Use those
+instead of talking directly to the GPIOs; they integrate with kernel
+frameworks better than your userspace code could.
+
+
+Paths in Sysfs
+--------------
+There are three kinds of entry in /sys/class/gpio:
+
+ - Control interfaces used to get userspace control over GPIOs;
+
+ - GPIOs themselves; and
+
+ - GPIO controllers ("gpio_chip" instances).
+
+That's in addition to standard files including the "device" symlink.
+
+The control interfaces are write-only:
+
+ /sys/class/gpio/
+
+ "export" ... Userspace may ask the kernel to export control of
+ a GPIO to userspace by writing its number to this file.
+
+ Example: "echo 19 > export" will create a "gpio19" node
+ for GPIO #19, if that's not requested by kernel code.
+
+ "unexport" ... Reverses the effect of exporting to userspace.
+
+ Example: "echo 19 > unexport" will remove a "gpio19"
+ node exported using the "export" file.
+
+GPIO signals have paths like /sys/class/gpio/gpio42/ (for GPIO #42)
+and have the following read/write attributes:
+
+ /sys/class/gpio/gpioN/
+
+ "direction" ... reads as either "in" or "out". This value may
+ normally be written. Writing as "out" defaults to
+ initializing the value as low. To ensure glitch free
+ operation, values "low" and "high" may be written to
+ configure the GPIO as an output with that initial value.
+
+ Note that this attribute *will not exist* if the kernel
+ doesn't support changing the direction of a GPIO, or
+ it was exported by kernel code that didn't explicitly
+ allow userspace to reconfigure this GPIO's direction.
+
+ "value" ... reads as either 0 (low) or 1 (high). If the GPIO
+ is configured as an output, this value may be written;
+ any nonzero value is treated as high.
+
+GPIO controllers have paths like /sys/class/gpio/chipchip42/ (for the
+controller implementing GPIOs starting at #42) and have the following
+read-only attributes:
+
+ /sys/class/gpio/gpiochipN/
+
+ "base" ... same as N, the first GPIO managed by this chip
+
+ "label" ... provided for diagnostics (not always unique)
+
+ "ngpio" ... how many GPIOs this manges (N to N + ngpio - 1)
+
+Board documentation should in most cases cover what GPIOs are used for
+what purposes. However, those numbers are not always stable; GPIOs on
+a daughtercard might be different depending on the base board being used,
+or other cards in the stack. In such cases, you may need to use the
+gpiochip nodes (possibly in conjunction with schematics) to determine
+the correct GPIO number to use for a given signal.
+
+
+Exporting from Kernel code
+--------------------------
+Kernel code can explicitly manage exports of GPIOs which have already been
+requested using gpio_request():
+
+ /* export the GPIO to userspace */
+ int gpio_export(unsigned gpio, bool direction_may_change);
+
+ /* reverse gpio_export() */
+ void gpio_unexport();
+
+After a kernel driver requests a GPIO, it may only be made available in
+the sysfs interface by gpio_export(). The driver can control whether the
+signal direction may change. This helps drivers prevent userspace code
+from accidentally clobbering important system state.
+
+This explicit exporting can help with debugging (by making some kinds
+of experiments easier), or can provide an always-there interface that's
+suitable for documenting as part of a board support package.

+
+
+Updating the client
+-------------------
+
+The new style binding model will check against a list of supported
+devices and their associated address supplied by the code registering
+the busses. This means that the driver .attach_adapter and
+.detach_adapter methods can be removed, along with the addr_data,
+as follows:
+
+- static struct i2c_driver example_driver;
+
+- static unsigned short ignore[] = { I2C_CLIENT_END };
+- static unsigned short normal_addr[] = { OUR_ADDR, I2C_CLIENT_END };
+
+- I2C_CLIENT_INSMOD;
+
+- static int example_attach_adapter(struct i2c_adapter *adap)
+- {

+
+ static struct i2c_driver example_driver = {
++ .probe = example_probe,
++ .remove = __devexit_p(example_remove),
+ }
+
+Change the example_attach method to accept the new parameters

+
+- static int example_attach(struct i2c_adapter *adap, int addr, int kind)
++ static int example_probe(struct i2c_client *client,
++ const struct i2c_device_id *id)
+
+Change the name of example_attach to example_probe to align it with the
+i2c_driver entry names. The rest of the probe routine will now need to be
+changed as the i2c_client has already been setup for use.
+
+The necessary client fields have already been setup before

+
+- example->client.addr = addr;
+- example->client.flags = 0;
+- example->client.adapter = adap;
+-
+- strlcpy(client->i2c_client.name, "example", I2C_NAME_SIZE);
+
+The i2c_set_clientdata is now:
+
+- i2c_set_clientdata(&state->client, state);
++ i2c_set_clientdata(client, state);
+
+The call to i2c_attach_client is no longer needed, if the probe
+routine exits successfully, then the driver will be automatically
+attached by the core. Change the probe routine as so:
+
+- ret = i2c_attach_client(&state->i2c_client);
+- if (ret < 0) {
+- dev_err(dev, "failed to attach client\n");
+- kfree(state);
+- return ret;
+- }
+
+
+Remove the storage of 'struct i2c_client' from the 'struct example_state'
+as we are provided with the i2c_client in our example_probe. Instead we
+store a pointer to it for when it is needed.
+
+struct example_state {
+- struct i2c_client client;
++ struct i2c_client *client;
+
+the new i2c client as so:
+
+- struct device *dev = &adap->dev; /* to use for dev_ reports */
++ struct device *dev = &i2c_client->dev; /* to use for dev_ reports */
+
+And remove the change after our client is attached, as the driver no
+longer needs to register a new client structure with the core:
+
+- dev = &state->i2c_client.dev;
+
+In the probe routine, ensure that the new state has the client stored
+in it:
+
+static int example_probe(struct i2c_client *i2c_client,
+ const struct i2c_device_id *id)
+{
+ struct example_state *state;
+ struct device *dev = &i2c_client->dev;
+ int ret;
+
+ state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
+ if (state == NULL) {
+ dev_err(dev, "failed to create our state\n");
+ return -ENOMEM;
+ }
+
++ state->client = i2c_client;
+
+Update the detach method, by changing the name to _remove and

+Paravirt_ops on IA64
+====================
+ 21 May 2008, Isaku Yamahata <yamahata@valinux.co.jp>
+
+
+Introduction
+------------
+The aim of this documentation is to help with maintainability and/or to
+encourage people to use paravirt_ops/IA64.
+
+paravirt_ops (pv_ops in short) is a way for virtualization support of
+Linux kernel on x86. Several ways for virtualization support were
+proposed, paravirt_ops is the winner.
+On the other hand, now there are also several IA64 virtualization
+technologies like kvm/IA64, xen/IA64 and many other academic IA64
+hypervisors so that it is good to add generic virtualization
+infrastructure on Linux/IA64.
+
+
+What is paravirt_ops?
+---------------------
+It has been developed on x86 as virtualization support via API, not ABI.
+It allows each hypervisor to override operations which are important for
+hypervisors at API level. And it allows a single kernel binary to run on
+all supported execution environments including native machine.
+Essentially paravirt_ops is a set of function pointers which represent
+operations corresponding to low level sensitive instructions and high
+level functionalities in various area. But one significant difference
+from usual function pointer table is that it allows optimization with
+binary patch. It is because some of these operations are very
+performance sensitive and indirect call overhead is not negligible.
+With binary patch, indirect C function call can be transformed into
+direct C function call or in-place execution to eliminate the overhead.
+
+Thus, operations of paravirt_ops are classified into three categories.
+- simple indirect call
+ These operations correspond to high level functionality so that the
+ overhead of indirect call isn't very important.
+
+- indirect call which allows optimization with binary patch
+ Usually these operations correspond to low level instructions. They
+ are called frequently and performance critical. So the overhead is
+ very important.
+
+- a set of macros for hand written assembly code
+ Hand written assembly codes (.S files) also need paravirtualization
+ because they include sensitive instructions or some of code paths in
+ them are very performance critical.
+
+
+The relation to the IA64 machine vector
+---------------------------------------
+Linux/IA64 has the IA64 machine vector functionality which allows the
+kernel to switch implementations (e.g. initialization, ipi, dma api...)
+depending on executing platform.
+We can replace some implementations very easily defining a new machine
+vector. Thus another approach for virtualization support would be
+enhancing the machine vector functionality.
+But paravirt_ops approach was taken because
+- virtualization support needs wider support than machine vector does.
+ e.g. low level instruction paravirtualization. It must be
+ initialized very early before platform detection.
+
+- virtualization support needs more functionality like binary patch.
+ Probably the calling overhead might not be very large compared to the
+ emulation overhead of virtualization. However in the native case, the
+ overhead should be eliminated completely.
+ A single kernel binary should run on each environment including native,
+ and the overhead of paravirt_ops on native environment should be as
+ small as possible.
+
+- for full virtualization technology, e.g. KVM/IA64 or
+ Xen/IA64 HVM domain, the result would be
+ (the emulated platform machine vector. probably dig) + (pv_ops).
+ This means that the virtualization support layer should be under
+ the machine vector layer.
+
+Possibly it might be better to move some function pointers from
+paravirt_ops to machine vector. In fact, Xen domU case utilizes both
+pv_ops and machine vector.
+
+
+IA64 paravirt_ops
+-----------------
+In this section, the concrete paravirt_ops will be discussed.
+Because of the architecture difference between ia64 and x86, the
+resulting set of functions is very different from x86 pv_ops.
+
+- C function pointer tables
+They are not very performance critical so that simple C indirect
+function call is acceptable. The following structures are defined at
+this moment. For details see linux/include/asm-ia64/paravirt.h
+ - struct pv_info
+ This structure describes the execution environment.
+ - struct pv_init_ops
+ This structure describes the various initialization hooks.
+ - struct pv_iosapic_ops
+ This structure describes hooks to iosapic operations.
+ - struct pv_irq_ops
+ This structure describes hooks to irq related operations
+ - struct pv_time_op
+ This structure describes hooks to steal time accounting.
+
+- a set of indirect calls which need optimization
+Currently this class of functions correspond to a subset of IA64
+intrinsics. At this moment the optimization with binary patch isn't
+implemented yet.
+struct pv_cpu_op is defined. For details see
+linux/include/asm-ia64/paravirt_privop.h
+Mostly they correspond to ia64 intrinsics 1-to-1.
+Caveat: Now they are defined as C indirect function pointers, but in
+order to support binary patch optimization, they will be changed
+using GCC extended inline assembly code.
+
+- a set of macros for hand written assembly code (.S files)
+For maintenance purpose, the taken approach for .S files is single
+source code and compile multiple times with different macros definitions.
+Each pv_ops instance must define those macros to compile.
+The important thing here is that sensitive, but non-privileged
+instructions must be paravirtualized and that some privileged
+instructions also need paravirtualization for reasonable performance.
+Developers who modify .S files must be aware of that. At this moment
+an easy checker is implemented to detect paravirtualization breakage.
+But it doesn't cover all the cases.
+
+Sometimes this set of macros is called pv_cpu_asm_op. But there is no
+corresponding structure in the source code.
+Those macros mostly 1:1 correspond to a subset of privileged
+instructions. See linux/include/asm-ia64/native/inst.h.
+And some functions written in assembly also need to be overrided so
+that each pv_ops instance have to define some macros. Again see
+linux/include/asm-ia64/native/inst.h.
+
+
+Those structures must be initialized very early before start_kernel.
+Probably initialized in head.S using multi entry point or some other trick.
+For native case implementation see linux/arch/ia64/kernel/paravirt.c.

+ need to do this procedure when:

-Driver Interface -- OBSOLETE, DO NOT USE!
-----------------*************************
-
-Note: pm_register(), pm_access(), pm_dev_idle() and friends are
-obsolete. Please do not use them. Instead you should properly hook
-your driver into the driver model, and use its suspend()/resume()
-callbacks to do this kind of stuff.
-
-If you are writing a new driver or maintaining an old driver, it
-should include power management support. Without power management
-support, a single driver may prevent a system with power management
-capabilities from ever being able to suspend (safely).
-
-Overview:
-1) Register each instance of a device with "pm_register"
-2) Call "pm_access" before accessing the hardware.
- (this will ensure that the hardware is awake and ready)
-3) Your "pm_callback" is called before going into a
- suspend state (ACPI D1-D3) or after resuming (ACPI D0)
- from a suspend.
-4) Call "pm_dev_idle" when the device is not being used
- (optional but will improve device idle detection)
-5) When unloaded, unregister the device with "pm_unregister"

-Driver Details
---------------
-This is just a quick Q&A as a stopgap until a real driver writers'
-power management guide is available.
-
-Q: When is a device suspended?
-
-Devices can be suspended based on direct user request (eg. laptop lid
-closes), system power policy (eg. sleep after 30 minutes of console
-inactivity), or device power policy (eg. power down device after 5
-minutes of inactivity)
-
-Q: Must a driver honor a suspend request?
-
-No, a driver can return -EBUSY from a suspend request and this
-will stop the system from suspending. When a suspend request
-fails, all suspended devices are resumed and the system continues
-to run. Suspend can be retried at a later time.
-
-Q: Can the driver block suspend/resume requests?
-
-Yes, a driver can delay its return from a suspend or resume
-request until the device is ready to handle requests. It
-is advantageous to return as quickly as possible from a
-request as suspend/resume are done serially.
-
-Q: What context is a suspend/resume initiated from?
-
-A suspend or resume is initiated from a kernel thread context.
-It is safe to block, allocate memory, initiate requests
-or anything else you can do within the kernel.
-
-Q: Will requests continue to arrive after a suspend?
-
-Possibly. It is the driver's responsibility to queue(*),
-fail, or drop any requests that arrive after returning
-success to a suspend request. It is important that the
-driver not access its device until after it receives
-a resume request as the device's bus may no longer
-be active.
-
-(*) If a driver queues requests for processing after
- resume be aware that the device, network, etc.
- might be in a different state than at suspend time.
- It's probably better to drop requests unless
- the driver is a storage device.
-
-Q: Do I have to manage bus-specific power management registers
-
-No. It is the responsibility of the bus driver to manage
-PCI, USB, etc. power management registers. The bus driver
-or the power management subsystem will also enable any
-wake-on functionality that the device has.
-
-Q: So, really, what do I need to do to support suspend/resume?
-
-You need to save any device context that would
-be lost if the device was powered off and then restore
-it at resume time. When ACPI is active, there are
-three levels of device suspend states; D1, D2, and D3.
-(The suspend state is passed as the "data" argument
-to the device callback.) With D3, the device is powered
-off and loses all context, D1 and D2 are shallower power
-states and require less device context to be saved. To
-play it safe, just save everything at suspend and restore
-everything at resume.
-
-Q: Where do I store device context for suspend?
-
-Anywhere in memory, kmalloc a buffer or store it
-in the device descriptor. You are guaranteed that the
-contents of memory will be restored and accessible
-before resume, even when the system suspends to disk.
-
-Q: What do I need to do for ACPI vs. APM vs. etc?
-
-Drivers need not be aware of the specific power management
-technology that is active. They just need to be aware
-of when the overlying power management system requests
-that they suspend or resume.
-
-Q: What about device dependencies?
-
-When a driver registers a device, the power management
-subsystem uses the information provided to build a
-tree of device dependencies (eg. USB device X is on
-USB controller Y which is on PCI bus Z) When power
-management wants to suspend a device, it first sends
-a suspend request to its driver, then the bus driver,
-and so on up to the system bus. Device resumes
-proceed in the opposite direction.
-
-Q: Who do I contact for additional information about
- enabling power management for my specific driver/device?
-
-ACPI Development mailing list: linux-acpi@vger.kernel.org
-
-System Interface -- OBSOLETE, DO NOT USE!
-----------------*************************
-If you are providing new power management support to Linux (ie.
-adding support for something like APM or ACPI), you should
-communicate with drivers through the existing generic power
-management interface.

+ s) SPI (Serial Peripheral Interface) busses
+
+ SPI busses can be described with a node for the SPI master device
+ and a set of child nodes for each SPI slave on the bus. For this
+ discussion, it is assumed that the system's SPI controller is in
+ SPI master mode. This binding does not describe SPI controllers
+ in slave mode.
+
+ The SPI master node requires the following properties:
+ - #address-cells - number of cells required to define a chip select
+ address on the SPI bus.
+ - #size-cells - should be zero.
+ - compatible - name of SPI bus controller following generic names
+ recommended practice.
+ No other properties are required in the SPI bus node. It is assumed
+ that a driver for an SPI bus device will understand that it is an SPI bus.
+ However, the binding does not attempt to define the specific method for
+ assigning chip select numbers. Since SPI chip select configuration is
+ flexible and non-standardized, it is left out of this binding with the
+ assumption that board specific platform code will be used to manage
+ chip selects. Individual drivers can define additional properties to
+ support describing the chip select layout.
+
+ SPI slave nodes must be children of the SPI master node and can
+ contain the following properties.
+ - reg - (required) chip select address of device.
+ - compatible - (required) name of SPI device following generic names
+ recommended practice
+ - spi-max-frequency - (required) Maximum SPI clocking speed of device in Hz

+===================================================================
+
+Devices on SOCs often have mechanisms for placing devices into low-power
+states that are decoupled from the devices' own register blocks. Sometimes,
+this information is more complicated than a cell-index property can
+reasonably describe. Thus, each device controlled in such a manner
+may contain a "sleep" property which describes these connections.
+
+The sleep property consists of one or more sleep resources, each of
+which consists of a phandle to a sleep controller, followed by a
+controller-specific sleep specifier of zero or more cells.
+
+The semantics of what type of low power modes are possible are defined
+by the sleep controller. Some examples of the types of low power modes
+that may be supported are:
+
+ - Dynamic: The device may be disabled or enabled at any time.
+ - System Suspend: The device may request to be disabled or remain
+ awake during system suspend, but will not be disabled until then.
+ - Permanent: The device is disabled permanently (until the next hard
+ reset).
+
+Some devices may share a clock domain with each other, such that they should
+only be suspended when none of the devices are in use. Where reasonable,
+such nodes should be placed on a virtual bus, where the bus has the sleep
+property. If the clock domain is shared among devices that cannot be
+reasonably grouped in this manner, then create a virtual sleep controller
+(similar to an interrupt nexus, except that defining a standardized
+sleep-map should wait until its necessity is demonstrated).

+Alignment vs. Networking
+========================
+
+On architectures that require aligned loads, networking requires that the IP
+header is aligned on a four-byte boundary to optimise the IP stack. For

+architectures this constant has the value 2 because the normal ethernet

+addresses can be very expensive and dwarf the cost of unaligned loads.

+For some ethernet hardware that cannot DMA to unaligned addresses like
+4*n+2 or non-ethernet hardware, this can be a problem, and it is then

-This document and the new uhci sources can be found on
- http://hotswap.in.tum.de/usb
-
-1. General issues
-
-1.1 Why a new UHCI driver, we already have one?!?
-
-Correct, but its internal structure got more and more mixed up by the (still
-ongoing) efforts to get isochronous transfers (ISO) to work.
-Since there is an increasing need for reliable ISO-transfers (especially
-for USB-audio needed by TS and for a DAB-USB-Receiver build by GA and DF),
-this state was a bit unsatisfying in our opinion, so we've decided (based
-on knowledge and experiences with the old UHCI driver) to start
-from scratch with a new approach, much simpler but at the same time more
-powerful.
-It is inspired by the way Win98/Win2000 handles USB requests via URBs,
-but it's definitely 100% free of MS-code and doesn't crash while
-unplugging an used ISO-device like Win98 ;-)
-Some code for HW setup and root hub management was taken from the
-original UHCI driver, but heavily modified to fit into the new code.
-The invention of the basic concept, and major coding were completed in two
-days (and nights) on the 16th and 17th of October 1999, now known as the
-great USB-October-Revolution started by GA, DF, and TS ;-)
-
-Since the concept is in no way UHCI dependent, we hope that it will also be
-transferred to the OHCI-driver, so both drivers share a common API.
-
-1.2. Advantages and disadvantages
-
-+ All USB transfer types work now!
-+ Asynchronous operation
-+ Simple, but powerful interface (only two calls for start and cancel)
-+ Easy migration to the new API, simplified by a compatibility API
-+ Simple usage of ISO transfers
-+ Automatic linking of requests
-+ ISO transfers allow variable length for each frame and striping
-+ No CPU dependent and non-portable atomic memory access, no asm()-inlines
-+ Tested on x86 and Alpha
-
-- Rewriting for ISO transfers needed
-
-1.3. Is there some compatibility to the old API?
-
-Yes, but only for control, bulk and interrupt transfers. We've implemented
-some wrapper calls for these transfer types. The usbcore works fine with
-these wrappers. For ISO there's no compatibility, because the old ISO-API
-and its semantics were unnecessary complicated in our opinion.
-
-1.4. What's really working?
-
-As said above, CTRL and BULK already work fine even with the wrappers,
-so legacy code wouldn't notice the change.
-Regarding to Thomas, ISO transfers now run stable with USB audio.
-INT transfers (e.g. mouse driver) work fine, too.
-
-1.5. Are there any bugs?
-
-No ;-)
-Hm...
-Well, of course this implementation needs extensive testing on all available
-hardware, but we believe that any fixes shouldn't harm the overall concept.
-
-1.6. What should be done next?
-
-A large part of the request handling seems to be identical for UHCI and
-OHCI, so it would be a good idea to extract the common parts and have only
-the HW specific stuff in uhci.c. Furthermore, all other USB device drivers
-should need URBification, if they use isochronous or interrupt transfers.
-One thing missing in the current implementation (and the old UHCI driver)
-is fair queueing for BULK transfers. Since this would need (in principle)
-the alteration of already constructed TD chains (to switch from depth to
-breadth execution), another way has to be found. Maybe some simple
-heuristics work with the same effect.
-
----------------------------------------------------------------------------
-
-2. Internal structure and mechanisms
-
-To get quickly familiar with the internal structures, here's a short
-description how the new UHCI driver works. However, the ultimate source of
-truth is only uhci.c!
-
-2.1. Descriptor structure (QHs and TDs)
-
-During initialization, the following skeleton is allocated in init_skel:
-
- framespecific | common chain
-
-framelist[]
-[ 0 ]-----> TD --> TD -------\
-[ 1 ]-----> TD --> TD --------> TD ----> QH -------> QH -------> QH ---> NULL
- ... TD --> TD -------/
-[1023]-----> TD --> TD ------/
-
- ^^ ^^ ^^ ^^ ^^ ^^
- 1024 TDs for 7 TDs for 1 TD for Start of Start of End Chain
- ISO INT (2-128ms) 1ms-INT CTRL Chain BULK Chain
-
-For each CTRL or BULK transfer a new QH is allocated and the containing data
-transfers are appended as (vertical) TDs. After building the whole QH with its
-dangling TDs, the QH is inserted before the BULK Chain QH (for CTRL) or
-before the End Chain QH (for BULK). Since only the QH->next pointers are
-affected, no atomic memory operation is required. The three QHs in the
-common chain are never equipped with TDs!
-
-For ISO or INT, the TD for each frame is simply inserted into the appropriate
-ISO/INT-TD-chain for the desired frame. The 7 skeleton INT-TDs are scattered
-among the 1024 frames similar to the old UHCI driver.
-
-For CTRL/BULK/ISO, the last TD in the transfer has the IOC-bit set. For INT,
-every TD (there is only one...) has the IOC-bit set.
-
-Besides the data for the UHCI controller (2 or 4 32bit words), the descriptors
-are double-linked through the .vertical and .horizontal elements in the
-SW data of the descriptor (using the double-linked list structures and
-operations), but SW-linking occurs only in closed domains, i.e. for each of
-the 1024 ISO-chains and the 8 INT-chains there is a closed cycle. This
-simplifies all insertions and unlinking operations and avoids costly
-bus_to_virt()-calls.
-
-2.2. URB structure and linking to QH/TDs
-
-During assembly of the QH and TDs of the requested action, these descriptors
-are stored in urb->urb_list, so the allocated QH/TD descriptors are bound to
-this URB.
-If the assembly was successful and the descriptors were added to the HW chain,
-the corresponding URB is inserted into a global URB list for this controller.
-This list stores all pending URBs.
-
-2.3. Interrupt processing
-
-Since UHCI provides no means to directly detect completed transactions, the
-following is done in each UHCI interrupt (uhci_interrupt()):
-
-For each URB in the pending queue (process_urb()), the ACTIVE-flag of the
-associated TDs are processed (depending on the transfer type
-process_{transfer|interrupt|iso}()). If the TDs are not active anymore,
-they indicate the completion of the transaction and the status is calculated.
-Inactive QH/TDs are removed from the HW chain (since the host controller
-already removed the TDs from the QH, no atomic access is needed) and
-eventually the URB is marked as completed (OK or errors) and removed from the
-pending queue. Then the next linked URB is submitted. After (or immediately
-before) that, the completion handler is called.
-
-2.4. Unlinking URBs
-
-First, all QH/TDs stored in the URB are unlinked from the HW chain.
-To ensure that the host controller really left a vertical TD chain, we
-wait for one frame. After that, the TDs are physically destroyed.
-
-2.5. URB linking and the consequences
-
-Since URBs can be linked and the corresponding submit_urb is called in
-the UHCI-interrupt, all work associated with URB/QH/TD assembly has to be
-interrupt save. This forces kmalloc to use GFP_ATOMIC in the interrupt.

- The maximum number of Unix98 PTYs that can be used at any one time.
- The default is 256, and should be enough for desktop systems. Server
- machines which support incoming telnet/rlogin/ssh connections and/or
- serve several X terminals may want to increase this: every incoming

+/* Sun4v hypervisor interfaces and defines.
+ *
+ * Hypervisor calls are made via traps to software traps number 0x80
+ * and above. Registers %o0 to %o5 serve as argument, status, and
+ * return value registers.
+ *
+ * There are two kinds of these traps. First there are the normal
+ * "fast traps" which use software trap 0x80 and encode the function
+ * to invoke by number in register %o5. Argument and return value
+ * handling is as follows:
+ *
+ * -----------------------------------------------
+ * | %o5 | function number | undefined |
+ * | %o0 | argument 0 | return status |
+ * | %o1 | argument 1 | return value 1 |
+ * | %o2 | argument 2 | return value 2 |
+ * | %o3 | argument 3 | return value 3 |
+ * | %o4 | argument 4 | return value 4 |
+ * -----------------------------------------------
+ *
+ * The second type are "hyper-fast traps" which encode the function
+ * number in the software trap number itself. So these use trap
+ * numbers > 0x80. The register usage for hyper-fast traps is as
+ * follows:
+ *
+ * -----------------------------------------------
+ * | %o0 | argument 0 | return status |
+ * | %o1 | argument 1 | return value 1 |
+ * | %o2 | argument 2 | return value 2 |
+ * | %o3 | argument 3 | return value 3 |
+ * | %o4 | argument 4 | return value 4 |
+ * -----------------------------------------------
+ *
+ * Registers providing explicit arguments to the hypervisor calls
+ * are volatile across the call. Upon return their values are
+ * undefined unless explicitly specified as containing a particular
+ * return value by the specific call. The return status is always
+ * returned in register %o0, zero indicates a successful execution of
+ * the hypervisor call and other values indicate an error status as
+ * defined below. So, for example, if a hyper-fast trap takes
+ * arguments 0, 1, and 2, then %o0, %o1, and %o2 are volatile across
+ * the call and %o3, %o4, and %o5 would be preserved.
+ *
+ * If the hypervisor trap is invalid, or the fast trap function number
+ * is invalid, HV_EBADTRAP will be returned in %o0. Also, all 64-bits
+ * of the argument and return values are significant.

+ *

+ * disabled, then the hypervisor take a platform specific action leading
+ * to guest termination within a bounded time period. The platform action
+ * may include recovery actions such as reporting the expiration to a
+ * Service Processor, and/or automatically restarting the gues.
+ *
+ * The 'timeout' parameter is specified in milliseconds, however the
+ * implementated granularity is given by the 'watchdog-resolution'
+ * property in the 'platform' node of the guest's machine description.
+ * The largest allowed timeout value is specified by the
+ * 'watchdog-max-timeout' property of the 'platform' node.
+ *
+ * If the 'timeout' argument is not zero, the watchdog timer is set to
+ * expire after a minimum of 'timeout' milliseconds.
+ *
+ * If the 'timeout' argument is zero, the watchdog timer is disabled.
+ *
+ * If the 'timeout' value exceeds the value of the 'max-watchdog-timeout'
+ * property, the hypervisor leaves the watchdog timer state unchanged,
+ * and returns a status of EINVAL.
+ *
+ * The 'time remaining' return value is valid regardless of whether the
+ * return status is EOK or EINVAL. A non-zero return value indicates the
+ * number of milliseconds that were remaining until the timer was to expire.
+ * If less than one millisecond remains, the return value is '1'. If the
+ * watchdog timer was disabled at the time of the call, the return value is
+ * zero.
+ *
+ * If the hypervisor cannot support the exact timeout value requested, but
+ * can support a larger timeout value, the hypervisor may round the actual
+ * timeout to a value larger than the requested timeout, consequently the
+ * 'time remaining' return value may be larger than the previously requested
+ * timeout value.
+ *
+ * Any guest OS debugger should be aware that the watchdog service may be in

+ *
+ * See the terminology descriptions in the device interrupt services

+ * definitions specific to these PCI IO services:
+ *
+ * tsbnum TSB number. Indentifies which io-tsb is used.
+ * For this version of the specification, tsbnum
+ * must be zero.
+ *
+ * tsbindex TSB index. Identifies which entry in the TSB
+ * is used. The first entry is zero.
+ *
+ * tsbid A 64-bit aligned data structure which contains
+ * a tsbnum and a tsbindex. Bits 63:32 contain the
+ * tsbnum and bits 31:00 contain the tsbindex.
+ *
+ * Use the HV_PCI_TSBID() macro to construct such
+ * values.
+ *
+ * io_attributes IO attributes for IOMMU mappings. One of more
+ * of the attritbute bits are stores in a 64-bit
+ * value. The values are defined below.
+ *
+ * r_addr 64-bit real address
+ *
+ * pci_device PCI device address. A PCI device address identifies
+ * a specific device on a specific PCI bus segment.
+ * A PCI device address ia a 32-bit unsigned integer
+ * with the following format:
+ *
+ * 00000000.bbbbbbbb.dddddfff.00000000
+ *
+ * Use the HV_PCI_DEVICE_BUILD() macro to construct
+ * such values.
+ *
+ * pci_config_offset
+ * PCI configureation space offset. For conventional
+ * PCI a value between 0 and 255. For extended
+ * configuration space, a value between 0 and 4095.
+ *
+ * Note: For PCI configuration space accesses, the offset
+ * must be aligned to the access size.
+ *
+ * error_flag A return value which specifies if the action succeeded
+ * or failed. 0 means no error, non-0 means some error
+ * occurred while performing the service.
+ *
+ * io_sync_direction
+ * Direction definition for pci_dma_sync(), defined
+ * below in HV_PCI_SYNC_*.
+ *
+ * io_page_list A list of io_page_addresses, an io_page_address is
+ * a real address.
+ *
+ * io_page_list_p A pointer to an io_page_list.
+ *
+ * "size based byte swap" - Some functions do size based byte swapping
+ * which allows sw to access pointers and
+ * counters in native form when the processor
+ * operates in a different endianness than the
+ * IO bus. Size-based byte swapping converts a
+ * multi-byte field between big-endian and
+ * little-endian format.

-This port to the NEC V850E processor supports the following platforms:
-
- "sim"
- The gdb v850e simulator (CONFIG_V850E_SIM).
-
- "rte-ma1-cb"
- The Midas labs RTE-V850E/MA1-CB and RTE-V850E/NB85E-CB evaluation
- boards (CONFIG_RTE_CB_MA1 and CONFIG_RTE_CB_NB85E). This support
- has only been tested when running with the Multi-debugger monitor
- ROM (for the Green Hills Multi debugger). The optional NEC
- Solution Gear RTE-MOTHER-A motherboard is also supported, which
- allows PCI boards to be used (CONFIG_RTE_MB_A_PCI).
-
- "rte-me2-cb"
- The Midas labs RTE-V850E/ME2-CB evaluation board (CONFIG_RTE_CB_ME2).
- This has only been tested using a kernel downloaded via an ICE
- connection using the Multi debugger. Support for the RTE-MOTHER-A is
- present, but hasn't been tested (unlike the other Midas labs cpu
- boards, the RTE-V850E/ME2-CB includes an ethernet adaptor).
-
- "as85ep1"
- The NEC AS85EP1 V850E evaluation chip/board (CONFIG_V850E_AS85EP1).
-
- "anna"
- The NEC `Anna' (board/chip) implementation of the V850E2 processor
- (CONFIG_V850E2_ANNA).
-
- "sim85e2c", "sim85e2s"
- The sim85e2c and sim85e2s simulators, which are verilog simulations
- of the V850E2 NA85E2C/NA85E2S cpu cores (CONFIG_V850E2_SIM85E2C and
- CONFIG_V850E2_SIM85E2S).
-
- "fpga85e2c"
- A FPGA implementation of the V850E2 NA85E2C cpu core
- (CONFIG_V850E2_FPGA85E2C).
-
-To get a default kernel configuration for a particular platform, you can
-use a <platform>_defconfig make target (e.g., "make rte-me2-cb_defconfig");
-to see which default configurations are possible, look in the directory
-"arch/v850/configs".
-
-Porting to anything with a V850E/MA1 or MA2 processor should be simple.
-See the file <asm-v850/machdep.h> and the files it includes for an example of
-how to add platform/chip-specific support.

+/* The Niagara2 RNG provides a 64-bit read-only random number
+ * register, plus a control register. Access to the RNG is
+ * virtualized through the hypervisor so that both guests and control
+ * nodes can access the device.
+ *
+ * The entropy source consists of raw entropy sources, each
+ * constructed from a voltage controlled oscillator whose phase is
+ * jittered by thermal noise sources.
+ *
+ * The oscillator in each of the three raw entropy sources run at
+ * different frequencies. Normally, all three generator outputs are
+ * gathered, xored together, and fed into a CRC circuit, the output of
+ * which is the 64-bit read-only register.
+ *
+ * Some time is necessary for all the necessary entropy to build up
+ * such that a full 64-bits of entropy are available in the register.
+ * In normal operating mode (RNG_CTL_LFSR is set), the chip implements
+ * an interlock which blocks register reads until sufficient entropy
+ * is available.
+ *
+ * A control register is provided for adjusting various aspects of RNG
+ * operation, and to enable diagnostic modes. Each of the three raw
+ * entropy sources has an enable bit (RNG_CTL_ES{1,2,3}). Also
+ * provided are fields for controlling the minimum time in cycles
+ * between read accesses to the register (RNG_CTL_WAIT, this controls
+ * the interlock described in the previous paragraph).
+ *
+ * The standard setting is to have the mode bit (RNG_CTL_LFSR) set,
+ * all three entropy sources enabled, and the interlock time set
+ * appropriately.
+ *
+ * The CRC polynomial used by the chip is:
+ *
+ * P(X) = x64 + x61 + x57 + x56 + x52 + x51 + x50 + x48 + x47 + x46 +
+ * x43 + x42 + x41 + x39 + x38 + x37 + x35 + x32 + x28 + x25 +
+ * x22 + x21 + x17 + x15 + x13 + x12 + x11 + x7 + x5 + x + 1
+ *
+ * The RNG_CTL_VCO value of each noise cell must be programmed
+ * seperately. This is why 4 control register values must be provided
+ * to the hypervisor. During a write, the hypervisor writes them all,
+ * one at a time, to the actual RNG_CTL register. The first three
+ * values are used to setup the desired RNG_CTL_VCO for each entropy
+ * source, for example:
+ *
+ * control 0: (1 << RNG_CTL_VCO_SHIFT) | RNG_CTL_ES1
+ * control 1: (2 << RNG_CTL_VCO_SHIFT) | RNG_CTL_ES2
+ * control 2: (3 << RNG_CTL_VCO_SHIFT) | RNG_CTL_ES3
+ *
+ * And then the fourth value sets the final chip state and enables
+ * desired.

+ * module parameters:
+ * type:
+ * By default (0), the card is automatically detected.
+ * Or use the following combinations:
+ * Bit 0-7 = 0x00001 = HFC-E1 (1 port)
+ * or Bit 0-7 = 0x00004 = HFC-4S (4 ports)
+ * or Bit 0-7 = 0x00008 = HFC-8S (8 ports)
+ * Bit 8 = 0x00100 = uLaw (instead of aLaw)
+ * Bit 9 = 0x00200 = Disable DTMF detect on all B-channels via hardware
+ * Bit 10 = spare
+ * Bit 11 = 0x00800 = Force PCM bus into slave mode. (otherwhise auto)
+ * or Bit 12 = 0x01000 = Force PCM bus into master mode. (otherwhise auto)
+ * Bit 13 = spare
+ * Bit 14 = 0x04000 = Use external ram (128K)
+ * Bit 15 = 0x08000 = Use external ram (512K)
+ * Bit 16 = 0x10000 = Use 64 timeslots instead of 32
+ * or Bit 17 = 0x20000 = Use 128 timeslots instead of anything else
+ * Bit 18 = spare
+ * Bit 19 = 0x80000 = Send the Watchdog a Signal (Dual E1 with Watchdog)
+ * (all other bits are reserved and shall be 0)
+ * example: 0x20204 one HFC-4S with dtmf detection and 128 timeslots on PCM
+ * bus (PCM master)
+ *
+ * port: (optional or required for all ports on all installed cards)
+ * HFC-4S/HFC-8S only bits:
+ * Bit 0 = 0x001 = Use master clock for this S/T interface
+ * (ony once per chip).
+ * Bit 1 = 0x002 = transmitter line setup (non capacitive mode)
+ * Don't use this unless you know what you are doing!
+ * Bit 2 = 0x004 = Disable E-channel. (No E-channel processing)
+ * example: 0x0001,0x0000,0x0000,0x0000 one HFC-4S with master clock
+ * received from port 1
+ *
+ * HFC-E1 only bits:
+ * Bit 0 = 0x0001 = interface: 0=copper, 1=optical
+ * Bit 1 = 0x0002 = reserved (later for 32 B-channels transparent mode)
+ * Bit 2 = 0x0004 = Report LOS
+ * Bit 3 = 0x0008 = Report AIS
+ * Bit 4 = 0x0010 = Report SLIP
+ * Bit 5 = 0x0020 = Report RDI
+ * Bit 8 = 0x0100 = Turn off CRC-4 Multiframe Mode, use double frame
+ * mode instead.
+ * Bit 9 = 0x0200 = Force get clock from interface, even in NT mode.
+ * or Bit 10 = 0x0400 = Force put clock to interface, even in TE mode.
+ * Bit 11 = 0x0800 = Use direct RX clock for PCM sync rather than PLL.
+ * (E1 only)
+ * Bit 12-13 = 0xX000 = elastic jitter buffer (1-3), Set both bits to 0
+ * for default.
+ * (all other bits are reserved and shall be 0)
+ *
+ * debug:
+ * NOTE: only one debug value must be given for all cards
+ * enable debugging (see hfc_multi.h for debug options)
+ *
+ * poll:
+ * NOTE: only one poll value must be given for all cards
+ * Give the number of samples for each fifo process.
+ * By default 128 is used. Decrease to reduce delay, increase to
+ * reduce cpu load. If unsure, don't mess with it!
+ * Valid is 8, 16, 32, 64, 128, 256.
+ *
+ * pcm:
+ * NOTE: only one pcm value must be given for every card.
+ * The PCM bus id tells the mISDNdsp module about the connected PCM bus.
+ * By default (0), the PCM bus id is 100 for the card that is PCM master.
+ * If multiple cards are PCM master (because they are not interconnected),
+ * each card with PCM master will have increasing PCM id.
+ * All PCM busses with the same ID are expected to be connected and have
+ * common time slots slots.
+ * Only one chip of the PCM bus must be master, the others slave.
+ * -1 means no support of PCM bus not even.

+ * NOTE: only one poll value must be given for every card.
+ * Also this value must be given for non-E1 cards. If omitted, the E1
+ * card has D-channel on time slot 16, which is default.
+ * If 1..15 or 17..31, an alternate time slot is used for D-channel.
+ * In this case, the application must be able to handle this.

+ * iomode:
+ * NOTE: only one mode value must be given for every card.
+ * -> See hfc_multi.h for HFC_IO_MODE_* values
+ * By default, the IO mode is pci memory IO (MEMIO).
+ * Some cards requre specific IO mode, so it cannot be changed.
+ * It may be usefull to set IO mode to register io (REGIO) to solve
+ * PCI bridge problems.
+ * If unsure, don't give this parameter.

+ * NOTE: only one clockdelay_nt value must be given once for all cards.
+ * Give the value of the clock control register (A_ST_CLK_DLY)

+ * how to encode a sample stream to 64-bit blocks that will be encryped
+ *
+ * first of all, data is collected until a block of 9 samples are received.
+ * of course, a packet may have much more than 9 sample, but is may have
+ * not excacly the multiple of 9 samples. if there is a rest, the next
+ * received data will complete the block.
+ *
+ * the block is then converted to 9 uLAW samples without the least sigificant
+ * bit. the result is a 7-bit encoded sample.
+ *
+ * the samples will be reoganised to form 8 bytes of data:
+ * (5(6) means: encoded sample no. 5, bit 6)
+ *
+ * 0(6) 0(5) 0(4) 0(3) 0(2) 0(1) 0(0) 1(6)
+ * 1(5) 1(4) 1(3) 1(2) 1(1) 1(0) 2(6) 2(5)
+ * 2(4) 2(3) 2(2) 2(1) 2(0) 3(6) 3(5) 3(4)
+ * 3(3) 3(2) 3(1) 3(0) 4(6) 4(5) 4(4) 4(3)
+ * 4(2) 4(1) 4(0) 5(6) 5(5) 5(4) 5(3) 5(2)
+ * 5(1) 5(0) 6(6) 6(5) 6(4) 6(3) 6(2) 6(1)
+ * 6(0) 7(6) 7(5) 7(4) 7(3) 7(2) 7(1) 7(0)
+ * 8(6) 8(5) 8(4) 8(3) 8(2) 8(1) 8(0)
+ *
+ * the missing bit 0 of the last byte is filled with some
+ * random noise, to fill all 8 bytes.
+ *
+ * the 8 bytes will be encrypted using blowfish.
+ *
+ * the result will be converted into 9 bytes. the bit 7 is used for
+ * checksumme (CS) for sync (0, 1) and for the last bit:
+ * (5(6) means: crypted byte 5, bit 6)
+ *
+ * 1 0(7) 0(6) 0(5) 0(4) 0(3) 0(2) 0(1)
+ * 0 0(0) 1(7) 1(6) 1(5) 1(4) 1(3) 1(2)
+ * 0 1(1) 1(0) 2(7) 2(6) 2(5) 2(4) 2(3)
+ * 0 2(2) 2(1) 2(0) 3(7) 3(6) 3(5) 3(4)
+ * 0 3(3) 3(2) 3(1) 3(0) 4(7) 4(6) 4(5)
+ * CS 4(4) 4(3) 4(2) 4(1) 4(0) 5(7) 5(6)
+ * CS 5(5) 5(4) 5(3) 5(2) 5(1) 5(0) 6(7)
+ * CS 6(6) 6(5) 6(4) 6(3) 6(2) 6(1) 6(0)
+ * 7(0) 7(6) 7(5) 7(4) 7(3) 7(2) 7(1) 7(0)
+ *
+ * the checksum is used to detect transmission errors and frame drops.
+ *
+ * synchronisation of received block is done by shifting the upper bit of each
+ * byte (bit 7) to a shift register. if the rigister has the first five bits
+ * (10000), this is used to find the sync. only if sync has been found, the
+ * current block of 9 received bytes are decrypted. before that the check
+ * sum is calculated. if it is incorrect the block is dropped.
+ * this will avoid loud noise due to corrupt encrypted data.
+ *
+ * if the last block is corrupt, the current decoded block is repeated
+ * until a valid block has been received.

+
+/*
+ * HOW THE CMX WORKS:
+ *
+ * There are 3 types of interaction: One member is alone, in this case only
+ * data flow from upper to lower layer is done.
+ * Two members will also exchange their data so they are crossconnected.
+ * Three or more members will be added in a conference and will hear each
+ * other but will not receive their own speech (echo) if not enabled.
+ *
+ * Features of CMX are:
+ * - Crossconnecting or even conference, if more than two members are together.
+ * - Force mixing of transmit data with other crossconnect/conference members.
+ * - Echo generation to benchmark the delay of audio processing.
+ * - Use hardware to minimize cpu load, disable FIFO load and minimize delay.
+ * - Dejittering and clock generation.
+ *
+ * There are 2 buffers:
+ *
+ *
+ * RX-Buffer
+ * R W
+ * | |
+ * ----------------+-------------+-------------------
+ *
+ * The rx-buffer is a ring buffer used to store the received data for each
+ * individual member. This is only the case if data needs to be dejittered
+ * or in case of a conference where different clocks require reclocking.
+ * The transmit-clock (R) will read the buffer.
+ * If the clock overruns the write-pointer, we will have a buffer underrun.
+ * If the write pointer always has a certain distance from the transmit-
+ * clock, we will have a delay. The delay will dynamically be increased and
+ * reduced.
+ *
+ *
+ * TX-Buffer
+ * R W
+ * | |
+ * -----------------+--------+-----------------------
+ *
+ * The tx-buffer is a ring buffer to queue the transmit data from user space
+ * until it will be mixed or sent. There are two pointers, R and W. If the write
+ * pointer W would reach or overrun R, the buffer would overrun. In this case
+ * (some) data is dropped so that it will not overrun.
+ * Additionally a dynamic dejittering can be enabled. this allows data from
+ * user space that have jitter and different clock source.
+ *
+ *
+ * Clock:
+ *
+ * A Clock is not required, if the data source has exactly one clock. In this
+ * case the data source is forwarded to the destination.
+ *
+ * A Clock is required, because the data source
+ * - has multiple clocks.
+ * - has no usable clock due to jitter or packet loss (VoIP).
+ * In this case the system's clock is used. The clock resolution depends on
+ * the jiffie resolution.
+ *
+ * If a member joins a conference:
+ *
+ * - If a member joins, its rx_buff is set to silence and change read pointer
+ * to transmit clock.
+ *
+ * The procedure of received data from card is explained in cmx_receive.
+ * The procedure of received data from user space is explained in cmx_transmit.
+ * The procedure of transmit data to card is cmx_send.
+ *
+ *
+ * Interaction with other features:
+ *
+ * DTMF:
+ * DTMF decoding is done before the data is crossconnected.
+ *
+ * Volume change:
+ * Changing rx-volume is done before the data is crossconnected. The tx-volume
+ * must be changed whenever data is transmitted to the card by the cmx.
+ *
+ * Tones:
+ * If a tone is enabled, it will be processed whenever data is transmitted to
+ * the card. It will replace the tx-data from the user space.
+ * If tones are generated by hardware, this conference member is removed for
+ * this time.
+ *
+ * Disable rx-data:
+ * If cmx is realized in hardware, rx data will be disabled if requested by
+ * the upper layer. If dtmf decoding is done by software and enabled, rx data
+ * will not be diabled but blocked to the upper layer.
+ *
+ * HFC conference engine:
+ * If it is possible to realize all features using hardware, hardware will be
+ * used if not forbidden by control command. Disabling rx-data provides
+ * absolutely traffic free audio processing. (except for the quick 1-frame
+ * upload of a tone loop, only once for a new tone)

+/* STRUCTURE:
+ *
+ * The dsp module provides layer 2 for b-channels (64kbit). It provides
+ * transparent audio forwarding with special digital signal processing:
+ *
+ * - (1) generation of tones
+ * - (2) detection of dtmf tones
+ * - (3) crossconnecting and conferences (clocking)
+ * - (4) echo generation for delay test
+ * - (5) volume control
+ * - (6) disable receive data
+ * - (7) pipeline
+ * - (8) encryption/decryption
+ *
+ * Look:

+ * ------card layer------
+ * TX RX
+ *
+ * Above you can see the logical data flow. If software is used to do the
+ * process, it is actually the real data flow. If hardware is used, data
+ * may not flow, but hardware commands to the card, to provide the data flow
+ * as shown.
+ *
+ * NOTE: The channel must be activated in order to make dsp work, even if
+ * no data flow to the upper layer is intended. Activation can be done
+ * after and before controlling the setting using PH_CONTROL requests.
+ *
+ * DTMF: Will be detected by hardware if possible. It is done before CMX
+ * processing.
+ *
+ * Tones: Will be generated via software if endless looped audio fifos are
+ * not supported by hardware. Tones will override all data from CMX.
+ * It is not required to join a conference to use tones at any time.
+ *
+ * CMX: Is transparent when not used. When it is used, it will do
+ * crossconnections and conferences via software if not possible through
+ * hardware. If hardware capability is available, hardware is used.
+ *
+ * Echo: Is generated by CMX and is used to check performane of hard and
+ * software CMX.
+ *
+ * The CMX has special functions for conferences with one, two and more
+ * members. It will allow different types of data flow. Receive and transmit
+ * data to/form upper layer may be swithed on/off individually without loosing
+ * features of CMX, Tones and DTMF.
+ *
+ * Echo Cancellation: Sometimes we like to cancel echo from the interface.
+ * Note that a VoIP call may not have echo caused by the IP phone. The echo
+ * is generated by the telephone line connected to it. Because the delay
+ * is high, it becomes an echo. RESULT: Echo Cachelation is required if
+ * both echo AND delay is applied to an interface.
+ * Remember that software CMX always generates a more or less delay.
+ *
+ * If all used features can be realized in hardware, and if transmit and/or
+ * receive data ist disabled, the card may not send/receive any data at all.
+ * Not receiving is usefull if only announcements are played. Not sending is
+ * usefull if an answering machine records audio. Not sending and receiving is
+ * usefull during most states of the call. If supported by hardware, tones
+ * will be played without cpu load. Small PBXs and NT-Mode applications will
+ * not need expensive hardware when processing calls.
+ *
+ *
+ * LOCKING:
+ *
+ * When data is received from upper or lower layer (card), the complete dsp
+ * module is locked by a global lock. This lock MUST lock irq, because it
+ * must lock timer events by DSP poll timer.
+ * When data is ready to be transmitted down, the data is queued and sent
+ * outside lock and timer event.
+ * PH_CONTROL must not change any settings, join or split conference members
+ * during process of data.
+ *
+ * HDLC:
+ *
+ * It works quite the same as transparent, except that HDLC data is forwarded
+ * to all other conference members if no hardware bridging is possible.
+ * Send data will be writte to sendq. Sendq will be sent if confirm is received.
+ * Conference cannot join, if one member is not hdlc.

+
+How the codec works:
+--------------------
+
+The volume is increased to increase the dynamic range of the audio signal.
+Each sample is converted to a-LAW with only 16 steps of level resolution.
+A pair of two samples are stored in one byte.
+
+The first byte is stored in the upper bits, the second byte is stored in the
+lower bits.
+
+To speed up compression and decompression, two lookup tables are formed:
+
+- 16 bits index for two samples (law encoded) with 8 bit compressed result.
+- 8 bits index for one compressed data with 16 bits decompressed result.
+
+NOTE: The bytes are handled as they are law-encoded.

+ Value 0 = transparent (default)
+ Value 1 = transfer ALAW
+ Value 2 = transfer ULAW
+ Value 3 = transfer generic 4 bit compression.

+ * ulaw:
+ 0 = we use a-Law (default)
+ 1 = we use u-Law
+
+ * limit:
+ limitation of B-channels to control bandwidth (1...126)
+ BRI: 1 or 2
+ PRI: 1-30, 31-126 (126, because dchannel ist not counted here)
+ Also limited ressources are used for stack, resulting in less channels.
+ It is possible to have more channels than 30 in PRI mode, this must
+ be supported by the application.
+
+ * ip:
+ byte representation of remote ip address (127.0.0.1 -> 127,0,0,1)
+ If not given or four 0, no remote address is set.
+ For multiple interfaces, concat ip addresses. (127,0,0,1,127,0,0,1)
+
+ * port:

+ If not given or 0, port 931 is used for fist instance, 932 for next...
+ For multiple interfaces, different ports must be given.
+
+ * remoteport:
+ port number (remote interface)
+ If not given or 0, remote port equals local port
+ For multiple interfaces on equal sites, different ports must be given.
+
+ * ondemand:
+ 0 = fixed (always transmit packets, even when remote side timed out)
+ 1 = on demand (only transmit packets, when remote side is detected)
+ the default is 0
+ NOTE: ID must also be set for on demand.
+
+ * id:
+ optional value to identify frames. This value must be equal on both

+
+* Only included in some cases.
+
+- Ver = Version
+If version is missmatch, the frame must be ignored.
+
+- T = Type of interface
+Must be 0 for S0 or 1 for E1.
+
+- I = Id present
+If bit is set, four ID bytes are included in frame.
+
+- ID = Connection ID
+Additional ID to prevent Denial of Service attacs. Also it prevents hijacking
+connections with dynamic IP. The ID should be random and must not be 0.
+
+- Coding = Type of codec
+Must be 0 for no transcoding. Also for D-channel and other HDLC frames.
+ 1 and 2 are reserved for explicitly use of a-LAW or u-LAW codec.
+ 3 is used for generic table compressor.
+
+- M = More channels to come. If this flag is 1, the following byte contains
+the length of the channel data. After the data block, the next channel will
+be defined. The flag for the last channel block (or if only one channel is
+transmitted), must be 0 and no length is given.
+
+- Channel = Channel number
+0 reserved
+1-3 channel data for S0 (3 is D-channel)
+1-31 channel data for E1 (16 is D-channel)
+32-127 channel data for extended E1 (16 is D-channel)
+
+- The length is used if the M-flag is 1. It is used to find the next channel
+inside frame.
+NOTE: A value of 0 equals 256 bytes of data.
+ -> For larger data blocks, a single frame must be used.
+ -> For larger streams, a single frame or multiple blocks with same channel ID
+ must be used.
+
+- Time Base = Timestamp of first sample in frame
+The "Time Base" is used to rearange packets and to detect packet loss.
+The 16 bits are sent in network order (MSB first) and count 1/8000 th of a
+second. This causes a wrap arround each 8,192 seconds. There is no requirement
+for the initial "Time Base", but 0 should be used for the first packet.
+In case of HDLC data, this timestamp counts the packet or byte number.
+
+
+Two Timers:
+
+After initialisation, a timer of 15 seconds is started. Whenever a packet is
+transmitted, the timer is reset to 15 seconds again. If the timer expires, an
+empty packet is transmitted. This keep the connection alive.
+
+When a valid packet is received, a timer 65 seconds is started. The interface
+become ACTIVE. If the timer expires, the interface becomes INACTIVE.
+
+
+Dynamic IP handling:
+
+To allow dynamic IP, the ID must be non 0. In this case, any packet with the
+correct port number and ID will be accepted. If the remote side changes its IP
+the new IP is used for all transmitted packets until it changes again.
+
+
+On Demand:
+
+If the ondemand parameter is given, the remote IP is set to 0 on timeout.
+This will stop keepalive traffic to remote. If the remote is online again,
+traffic will continue to the remote address. This is usefull for road warriors.
+This feature only works with ID set, otherwhise it is highly unsecure.
+
+
+Socket and Thread
+-----------------
+
+The complete socket opening and closing is done by a thread.
+When the thread opened a socket, the hc->socket descriptor is set. Whenever a
+packet shall be sent to the socket, the hc->socket must be checked wheter not
+NULL. To prevent change in socket descriptor, the hc->socket_lock must be used.
+To change the socket, a recall of l1oip_socket_open() will safely kill the
+socket process and create a new one.

+ * within the device tree. SPI and I2C are the two current users of this

+ *
+ * In most cases, devices do not need to be listed in this table because
+ * the modalias value can be derived directly from the compatible table.
+ * However, if for any reason a value cannot be derived, then this table
+ * provides a method to override the implicit derivation.
+ *
+ * At the moment, a single table is used for all bus types because it is
+ * assumed that the data size is small and that the compatible values
+ * should already be distinct enough to differentiate between SPI, I2C
+ * and other devices.

+ *
+ * - Second there's its limited range (we could increase it a bit by

+ * - Third there's the choice of two alarms and alarm signals.
+ * Here we use ALM0 and expect that nINT0 (open drain) is used;
+ * that's the only real option for DS1306 runtime alarms, and is
+ * natural on DS1305.
+ *
+ * - Fourth, there's also ALM1, and a second interrupt signal:
+ * + On DS1305 ALM1 uses nINT1 (when INTCN=1) else nINT0;
+ * + On DS1306 ALM1 only uses INT1 (an active high pulse)
+ * and it won't work when VCC1 is active.
+ *
+ * So to be most general, we should probably set both alarms to the
+ * same value, letting ALM1 be the wakeup event source on DS1306
+ * and handling several wiring options on DS1305.
+ *
+ * - Fifth, we support the polled mode (as well as possible; why not?)

+ * This function is an RNDIS Ethernet port -- a Microsoft protocol that's
+ * been promoted instead of the standard CDC Ethernet. The published RNDIS
+ * spec is ambiguous, incomplete, and needlessly complex. Variants such as
+ * ActiveSync have even worse status in terms of specification.
+ *
+ * In short: it's a protocol controlled by (and for) Microsoft, not for an
+ * Open ecosystem or markets. Linux supports it *only* because Microsoft
+ * doesn't support the CDC Ethernet standard.
+ *
+ * The RNDIS data transfer model is complex, with multiple Ethernet packets
+ * per USB message, and out of band data. The control model is built around
+ * what's essentially an "RNDIS RPC" protocol. It's all wrapped in a CDC ACM
+ * (modem, not Ethernet) veneer, with those ACM descriptors being entirely
+ * useless (they're ignored). RNDIS expects to be the only function in its
+ * configuration, so it's no real help if you need composite devices; and
+ * it expects to be the first configuration too.
+ *
+ * There is a single technical advantage of RNDIS over CDC Ethernet, if you
+ * discount the fluff that its RPC can be made to deliver: it doesn't need
+ * a NOP altsetting for the data interface. That lets it work on some of the
+ * "so smart it's stupid" hardware which takes over configuration changes
+ * from the software, and adds restrictions like "no altsettings".
+ *
+ * Unfortunately MSFT's RNDIS drivers are buggy. They hang or oops, and
+ * have all sorts of contrary-to-specification oddities that can prevent
+ * them from working sanely. Since bugfixes (or accurate specs, letting
+ * Linux work around those bugs) are unlikely to ever come from MSFT, you
+ * may want to avoid using RNDIS on purely operational grounds.
+ *
+ * Omissions from the RNDIS 1.0 specification include:
+ *
+ * - Power management ... references data that's scattered around lots
+ * of other documentation, which is incorrect/incomplete there too.
+ *
+ * - There are various undocumented protocol requirements, like the need
+ * to send garbage in some control-OUT messages.
+ *
+ * - MS-Windows drivers sometimes emit undocumented requests.

+ *
+ * This just sinks bulk packets OUT to the peripheral and sources them IN
+ * to the host, optionally with specific data patterns for integrity tests.
+ * As such it supports basic functionality and load tests.
+ *
+ * In terms of control messaging, this supports all the standard requests
+ * plus two that support control-OUT tests. If the optional "autoresume"
+ * mode is enabled, it provides good functional coverage for the "USBCV"
+ * test harness from USB-IF.
+ *
+ * Note that because this doesn't queue more than one request at a time,
+ * some other function must be used to test queueing logic. The network
+ * link (g_ether) is the best overall option for that, since its TX and RX
+ * queues are relatively independent, will receive a range of packet sizes,
+ * and can often be made to run out completely. Those issues are important
+ * when stress testing peripheral controller drivers.

+ * This function packages a simple "CDC Subset" Ethernet port with no real
+ * control mechanisms; just raw data transfer over two bulk endpoints.
+ * The data transfer model is exactly that of CDC Ethernet, which is
+ * why we call it the "CDC Subset".
+ *
+ * Because it's not standardized, this has some interoperability issues.
+ * They mostly relate to driver binding, since the data transfer model is
+ * so simple (CDC Ethernet). The original versions of this protocol used
+ * specific product/vendor IDs: byteswapped IDs for Digital Equipment's
+ * SA-1100 "Itsy" board, which could run Linux 2.4 kernels and supported
+ * daughtercards with USB peripheral connectors. (It was used more often
+ * with other boards, using the Itsy identifiers.) Linux hosts recognized
+ * this with CONFIG_USB_ARMLINUX; these devices have only one configuration
+ * and one interface.
+ *
+ * At some point, MCCI defined a (nonconformant) CDC MDLM variant called
+ * "SAFE", which happens to have a mode which is identical to the "CDC
+ * Subset" in terms of data transfer and lack of control model. This was
+ * adopted by later Sharp Zaurus models, and by some other software which
+ * Linux hosts recognize with CONFIG_USB_NET_ZAURUS.
+ *
+ * Because Microsoft's RNDIS drivers are far from robust, we added a few
+ * descriptors to the CDC Subset code, making this code look like a SAFE
+ * implementation. This lets you use MCCI's host side MS-Windows drivers
+ * if you get fed up with RNDIS. It also makes it easier for composite
+ * drivers to work, since they can use class based binding instead of
+ * caring about specific product and vendor IDs.

+ * This component encapsulates the TTY layer glue needed to provide basic
+ * "serial port" functionality through the USB gadget stack. Each such
+ * port is exposed through a /dev/ttyGS* node.
+ *
+ * After initialization (gserial_setup), these TTY port devices stay
+ * available until they are removed (gserial_cleanup). Each one may be
+ * connected to a USB function (gserial_connect), or disconnected (with
+ * gserial_disconnect) when the USB host issues a config change event.
+ * Data can only flow when the port is connected to the host.
+ *
+ * A given TTY port can be made available in multiple configurations.
+ * For example, each one might expose a ttyGS0 node which provides a
+ * login application. In one case that might use CDC ACM interface 0,
+ * while another configuration might use interface 3 for that. The
+ * work to handle that (including descriptor management) is not part
+ * of this component.
+ *
+ * Configurations may expose more than one TTY port. For example, if
+ * ttyGS0 provides login service, then ttyGS1 might provide dialer access
+ * for a telephone or fax link. And ttyGS2 might be something that just
+ * needs a simple byte stream interface for some messaging protocol that
+ * is managed in userspace ... OBEX, PTP, and MTP have been mentioned.

Code in this driver inspired by and in a number of places taken
from Brian Warner's original Keyspan-PDA driver.
This driver has been put together with the support of Innosys, Inc.
and Keyspan, Inc the manufacturers of the Keyspan USB-serial products.
Thanks Guys :)

Thanks to Paulus for miscellaneous tidy ups, some largish chunks
of much nicer and/or completely new code and (perhaps most uniquely)
having the patience to sit down and explain why and where he'd changed
- stuff.

- Tip 'o the hat to IBM (and previously Linuxcare :) for supporting

- This is a virtual file system providing information about the status
- of the system. "Virtual" means that it doesn't take up any space on
- your hard disk: the files are created on the fly by the kernel when
- you try to access them. Also, you cannot read the files with older
- version of the program less: you need to use more or cat.
-
- It's totally cool; for example, "cat /proc/interrupts" gives
- information about what the different IRQs are used for at the moment
- (there is a small number of Interrupt ReQuest lines in your computer
- that are used by the attached devices to gain the CPU's attention --
- often a source of trouble if two devices are mistakenly configured
- to use the same IRQ). The program procinfo to display some
- information about your system gathered from the /proc file system.
-
- Before you can use the /proc file system, it has to be mounted,
- meaning it has to be given a location in the directory hierarchy.
- That location should be /proc. A command such as "mount -t proc proc
- /proc" or the equivalent line in /etc/fstab does the job.
-
- The /proc file system is explained in the file
- <file:Documentation/filesystems/proc.txt> and on the proc(5) manpage
- ("man 5 proc").

- modifiable sysctl entries will be generated beneath the
- /proc/sys directory. They are explained in the files
- in <file:Documentation/sysctl/>. Note that enabling this
- option will enlarge the kernel by at least 8 KB.

- A new kernel-userspace API had to be introduced for Coda v6.0
- to support larger 128-bit file identifiers as needed by the
- new realms implementation.
-
- However this new API is not backward compatible with older
- clients. If you really need to run the old Coda userspace

+ help
+ This is a virtual file system providing information about the status
+ of the system. "Virtual" means that it doesn't take up any space on
+ your hard disk: the files are created on the fly by the kernel when
+ you try to access them. Also, you cannot read the files with older
+ version of the program less: you need to use more or cat.
+
+ It's totally cool; for example, "cat /proc/interrupts" gives
+ information about what the different IRQs are used for at the moment
+ (there is a small number of Interrupt ReQuest lines in your computer
+ that are used by the attached devices to gain the CPU's attention --
+ often a source of trouble if two devices are mistakenly configured
+ to use the same IRQ). The program procinfo to display some
+ information about your system gathered from the /proc file system.
+
+ Before you can use the /proc file system, it has to be mounted,
+ meaning it has to be given a location in the directory hierarchy.
+ That location should be /proc. A command such as "mount -t proc proc
+ /proc" or the equivalent line in /etc/fstab does the job.
+
+ The /proc file system is explained in the file
+ <file:Documentation/filesystems/proc.txt> and on the proc(5) manpage
+ ("man 5 proc").
+
+ This option will enlarge your kernel by about 67 KB. Several
+ programs depend on this, so everyone should say Y here.

+ default y
+ ---help---
+ The sysctl interface provides a means of dynamically changing
+ certain kernel parameters and variables on the fly without requiring
+ a recompile of the kernel or reboot of the system. The primary
+ interface is through /proc/sys. If you say Y here a tree of
+ modifiable sysctl entries will be generated beneath the
+ /proc/sys directory. They are explained in the files
+ in <file:Documentation/sysctl/>. Note that enabling this
+ option will enlarge the kernel by at least 8 KB.
+
+ As it is generally a good thing, you should say Y here unless
+ building a kernel for install/rescue disks or your system is very
+ limited in memory.

-/* Sun4v hypervisor interfaces and defines.
- *
- * Hypervisor calls are made via traps to software traps number 0x80
- * and above. Registers %o0 to %o5 serve as argument, status, and
- * return value registers.
- *
- * There are two kinds of these traps. First there are the normal
- * "fast traps" which use software trap 0x80 and encode the function
- * to invoke by number in register %o5. Argument and return value
- * handling is as follows:
- *
- * -----------------------------------------------
- * | %o5 | function number | undefined |
- * | %o0 | argument 0 | return status |
- * | %o1 | argument 1 | return value 1 |
- * | %o2 | argument 2 | return value 2 |
- * | %o3 | argument 3 | return value 3 |
- * | %o4 | argument 4 | return value 4 |
- * -----------------------------------------------
- *
- * The second type are "hyper-fast traps" which encode the function
- * number in the software trap number itself. So these use trap
- * numbers > 0x80. The register usage for hyper-fast traps is as
- * follows:
- *
- * -----------------------------------------------
- * | %o0 | argument 0 | return status |
- * | %o1 | argument 1 | return value 1 |
- * | %o2 | argument 2 | return value 2 |
- * | %o3 | argument 3 | return value 3 |
- * | %o4 | argument 4 | return value 4 |
- * -----------------------------------------------
- *
- * Registers providing explicit arguments to the hypervisor calls
- * are volatile across the call. Upon return their values are
- * undefined unless explicitly specified as containing a particular
- * return value by the specific call. The return status is always
- * returned in register %o0, zero indicates a successful execution of
- * the hypervisor call and other values indicate an error status as
- * defined below. So, for example, if a hyper-fast trap takes
- * arguments 0, 1, and 2, then %o0, %o1, and %o2 are volatile across
- * the call and %o3, %o4, and %o5 would be preserved.
- *
- * If the hypervisor trap is invalid, or the fast trap function number
- * is invalid, HV_EBADTRAP will be returned in %o0. Also, all 64-bits
- * of the argument and return values are significant.

- * ARG0: timeout in milliseconds

- *
- * A guest uses this API to set a watchdog timer. Once the gues has set
- * the timer, it must call the timer service again either to disable or
- * postpone the expiration. If the timer expires before being reset or
- * disabled, then the hypervisor take a platform specific action leading
- * to guest termination within a bounded time period. The platform action
- * may include recovery actions such as reporting the expiration to a
- * Service Processor, and/or automatically restarting the gues.
- *
- * The 'timeout' parameter is specified in milliseconds, however the
- * implementated granularity is given by the 'watchdog-resolution'
- * property in the 'platform' node of the guest's machine description.
- * The largest allowed timeout value is specified by the
- * 'watchdog-max-timeout' property of the 'platform' node.
- *
- * If the 'timeout' argument is not zero, the watchdog timer is set to
- * expire after a minimum of 'timeout' milliseconds.
- *
- * If the 'timeout' argument is zero, the watchdog timer is disabled.
- *
- * If the 'timeout' value exceeds the value of the 'max-watchdog-timeout'
- * property, the hypervisor leaves the watchdog timer state unchanged,
- * and returns a status of EINVAL.
- *
- * The 'time remaining' return value is valid regardless of whether the
- * return status is EOK or EINVAL. A non-zero return value indicates the
- * number of milliseconds that were remaining until the timer was to expire.
- * If less than one millisecond remains, the return value is '1'. If the
- * watchdog timer was disabled at the time of the call, the return value is
- * zero.
- *
- * If the hypervisor cannot support the exact timeout value requested, but
- * can support a larger timeout value, the hypervisor may round the actual
- * timeout to a value larger than the requested timeout, consequently the
- * 'time remaining' return value may be larger than the previously requested
- * timeout value.
- *
- * Any guest OS debugger should be aware that the watchdog service may be in
- * use. Consequently, it is recommended that the watchdog service is
- * disabled upon debugger entry (e.g. reaching a breakpoint), and then
- * re-enabled upon returning to normal execution. The API has been designed
- * with this in mind, and the 'time remaining' result of the disable call may
- * be used directly as the timeout argument of the re-enable call.

- *
- * See the terminology descriptions in the device interrupt services

- *
- * tsbnum TSB number. Indentifies which io-tsb is used.
- * For this version of the specification, tsbnum
- * must be zero.
- *
- * tsbindex TSB index. Identifies which entry in the TSB
- * is used. The first entry is zero.
- *
- * tsbid A 64-bit aligned data structure which contains
- * a tsbnum and a tsbindex. Bits 63:32 contain the
- * tsbnum and bits 31:00 contain the tsbindex.
- *
- * Use the HV_PCI_TSBID() macro to construct such
- * values.
- *
- * io_attributes IO attributes for IOMMU mappings. One of more
- * of the attritbute bits are stores in a 64-bit
- * value. The values are defined below.
- *
- * r_addr 64-bit real address
- *
- * pci_device PCI device address. A PCI device address identifies
- * a specific device on a specific PCI bus segment.
- * A PCI device address ia a 32-bit unsigned integer
- * with the following format:
- *
- * 00000000.bbbbbbbb.dddddfff.00000000
- *
- * Use the HV_PCI_DEVICE_BUILD() macro to construct
- * such values.
- *
- * pci_config_offset
- * PCI configureation space offset. For conventional
- * PCI a value between 0 and 255. For extended
- * configuration space, a value between 0 and 4095.
- *
- * Note: For PCI configuration space accesses, the offset
- * must be aligned to the access size.
- *
- * error_flag A return value which specifies if the action succeeded
- * or failed. 0 means no error, non-0 means some error
- * occurred while performing the service.
- *
- * io_sync_direction
- * Direction definition for pci_dma_sync(), defined
- * below in HV_PCI_SYNC_*.
- *
- * io_page_list A list of io_page_addresses, an io_page_address is
- * a real address.
- *
- * io_page_list_p A pointer to an io_page_list.
- *
- * "size based byte swap" - Some functions do size based byte swapping
- * which allows sw to access pointers and
- * counters in native form when the processor
- * operates in a different endianness than the
- * IO bus. Size-based byte swapping converts a
- * multi-byte field between big-endian and

- * was one instruction after the branch delay slot and the chip still hung.
- * The offending sequence was the following in sym_wakeup_done() of the

- *
- * call sym_ccb_from_dsa, 0
- * movge %icc, 0, %l0
- * brz,pn %o0, .LL1303
- * mov %o0, %l2
- * membar #LoadLoad
- *

- forcing gcc to do arithmetic on the value is usually enough to get it

- * copy of the task_struct, which is currently not used by gdb,
- * but it may come in handy at some point. All of the registers
- * are stored as part of the upage. The upage should always be
- * only one page long.
- * data: The data segment follows next. We use current->end_text to
- * current->brk to pick up all of the user variables, plus any memory
- * that may have been sbrk'ed. No attempt is made to determine if a
- * page is demand-zero or if a page is totally unused, we just cover
- * the entire range. All of the addresses are rounded in such a way
- * that an integral number of pages is written.
- * stack: We need the stack information in order to get a meaningful
- * backtrace. We need to write the data from usp to
- * current->start_stack, so we round each of these in order to be able
- * to write an integer number of pages.

+ * This function must be called inside the same rcu_read_lock() section as has
+ * been used to lookup the page in the pagecache radix-tree (or page table):
+ * this allows allocators to use a synchronize_rcu() to stabilize _count.
+ *
+ * Unless an RCU grace period has passed, the count of all pages coming out
+ * of the allocator must be considered unstable. page_count may return higher
+ * than expected, and put_page must be able to do the right thing when the
+ * page has been finished with, no matter what it is subsequently allocated
+ * for (because put_page is what is used here to drop an invalid speculative
+ * reference).
+ *
+ * This is the interesting part of the lockless pagecache (and lockless
+ * get_user_pages) locking protocol, where the lookup-side (eg. find_get_page)
+ * has the following pattern:
+ * 1. find page in radix tree
+ * 2. conditionally increment refcount
+ * 3. check the page is still in pagecache (if no, goto 1)
+ *
+ * Remove-side that cares about stability of _count (eg. reclaim) has the
+ * following (with tree_lock held for write):
+ * A. atomically check refcount is correct and set it to 0 (atomic_cmpxchg)
+ * B. remove page from pagecache
+ * C. free the page
+ *
+ * There are 2 critical interleavings that matter:
+ * - 2 runs before A: in this case, A sees elevated refcount and bails out
+ * - A runs before 2: in this case, 2 sees zero refcount and retries;
+ * subsequently, B will complete and 1 will find no page, causing the
+ * lookup to return NULL.
+ *
+ * It is possible that between 1 and 2, the page is removed then the exact same
+ * page is inserted into the same position in pagecache. That's OK: the
+ * old find_get_page using tree_lock could equally have run before or after
+ * such a re-insertion, depending on order that locks are granted.
+ *
+ * Lookups racing against pagecache insertion isn't a big problem: either 1

+ *
+ * This file defines hook entry points called by core code where
+ * user tracing/debugging support might need to do something. These
+ * entry points are called tracehook_*(). Each hook declared below
+ * has a detailed kerneldoc comment giving the context (locking et
+ * al) from which it is called, and the meaning of its return value.
+ *
+ * Each function here typically has only one call site, so it is ok
+ * to have some nontrivial tracehook_*() inlines. In all cases, the
+ * fast path when no tracing is enabled should be very short.
+ *
+ * The purpose of this file and the tracehook_* layer is to consolidate
+ * the interface that the kernel core and arch code uses to enable any
+ * user debugging or tracing facility (such as ptrace). The interfaces
+ * here are carefully documented so that maintainers of core and arch
+ * code do not need to think about the implementation details of the
+ * tracing facilities. Likewise, maintainers of the tracing code do not
+ * need to understand all the calling core or arch code in detail, just
+ * documented circumstances of each call, such as locking conditions.
+ *
+ * If the calling core code changes so that locking is different, then
+ * it is ok to change the interface documented here. The maintainer of
+ * core code changing should notify the maintainers of the tracing code
+ * that they need to work out the change.
+ *
+ * Some tracehook_*() inlines take arguments that the current tracing
+ * implementations might not necessarily use. These function signatures
+ * are chosen to pass in all the information that is on hand in the
+ * caller and might conceivably be relevant to a tracer, so that the
+ * core code won't have to be updated when tracing adds more features.
+ * If a call site changes so that some of those parameters are no longer
+ * already on hand without extra work, then the tracehook_* interface
+ * can change so there is no make-work burden on the core code. The
+ * maintainer of core code changing should notify the maintainers of the
+ * tracing code that they need to work out the change.

+ * @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may
+ * initialize usb_ep.driver data at this time (when it is used).
+ * Note that setting an interface to its current altsetting resets

+ * @get_alt: Returns the active altsetting. If this is not provided,

+ * @resume: Notifies functions when the host restarts USB traffic.
+ *
+ * A single USB function uses one or more interfaces, and should in most
+ * cases support operation at both full and high speeds. Each function is
+ * associated by @usb_add_function() with a one configuration; that function
+ * causes @bind() to be called so resources can be allocated as part of
+ * setting up a gadget driver. Those resources include endpoints, which
+ * should be allocated using @usb_ep_autoconfig().
+ *
+ * To support dual speed operation, a function driver provides descriptors
+ * for both high and full speed operation. Except in rare cases that don't
+ * involve bulk endpoints, each speed needs different endpoint descriptors.
+ *
+ * Function drivers choose their own strategies for managing instance data.
+ * The simplest strategy just declares it "static', which means the function
+ * can only be activated once. If the function needs to be exposed in more
+ * than one configuration at a given speed, it needs to support multiple
+ * usb_function structures (one for each configuration).
+ *
+ * A more complex strategy might encapsulate a @usb_function structure inside
+ * a driver-specific instance structure to allows multiple activations. An
+ * example of multiple activations might be a CDC ACM function that supports
+ * two or more distinct instances within the same configuration, providing
+ * several independent logical data links to a USB host.

+
+Diffconfig is a simple utility for comparing two .config files.
+Using standard diff to compare .config files often includes extraneous and
+distracting information. This utility produces sorted output with only the
+changes in configuration values between the two files.
+
+Added and removed items are shown with a leading plus or minus, respectively.
+Changed items show the old and new values on a single line.
+
+If -m is specified, then output will be in "merge" style, which has the
+changed and new values in kernel config option format.
+
+If no config files are specified, .config and .config.old are used.
+
+Example usage:
+ $ diffconfig .config config-with-some-changes
