Well, not for some odd devices. See the next section for information
about that.
- DAC Addressing for Address Space Hungry Devices
-
-There exists a class of devices which do not mesh well with the PCI
-DMA mapping API. By definition these "mappings" are a finite
-resource. The number of total available mappings per bus is platform
-specific, but there will always be a reasonable amount.
-
-What is "reasonable"? Reasonable means that networking and block I/O
-devices need not worry about using too many mappings.
-
-As an example of a problematic device, consider compute cluster cards.
-They can potentially need to access gigabytes of memory at once via
-DMA. Dynamic mappings are unsuitable for this kind of access pattern.
-
-To this end we've provided a small API by which a device driver
-may use DAC cycles to directly address all of physical memory.
-Not all platforms support this, but most do. It is easy to determine
-whether the platform will work properly at probe time.
-
-First, understand that there may be a SEVERE performance penalty for
-using these interfaces on some platforms. Therefore, you MUST only
-use these interfaces if it is absolutely required. %99 of devices can
-use the normal APIs without any problems.
-
-Note that for streaming type mappings you must either use these
-interfaces, or the dynamic mapping interfaces above. You may not mix
-usage of both for the same device. Such an act is illegal and is
-guaranteed to put a banana in your tailpipe.
-
-However, consistent mappings may in fact be used in conjunction with
-these interfaces. Remember that, as defined, consistent mappings are
-always going to be SAC addressable.
-
-The first thing your driver needs to do is query the PCI platform
-layer if it is capable of handling your devices DAC addressing
-capabilities:
-
- int pci_dac_dma_supported(struct pci_dev *hwdev, u64 mask);
-
-You may not use the following interfaces if this routine fails.
-
-Next, DMA addresses using this API are kept track of using the
-dma64_addr_t type. It is guaranteed to be big enough to hold any
-DAC address the platform layer will give to you from the following
-routines. If you have consistent mappings as well, you still
-use plain dma_addr_t to keep track of those.
-
-All mappings obtained here will be direct. The mappings are not
-translated, and this is the purpose of this dialect of the DMA API.
-
-All routines work with page/offset pairs. This is the _ONLY_ way to
-portably refer to any piece of memory. If you have a cpu pointer
-(which may be validly DMA'd too) you may easily obtain the page
-and offset using something like this:
-
- struct page *page = virt_to_page(ptr);
- unsigned long offset = offset_in_page(ptr);
-
-Here are the interfaces:
-
- dma64_addr_t pci_dac_page_to_dma(struct pci_dev *pdev,
- struct page *page,
- unsigned long offset,
- int direction);
-
-The DAC address for the tuple PAGE/OFFSET are returned. The direction
-argument is the same as for pci_{map,unmap}_single(). The same rules
-for cpu/device access apply here as for the streaming mapping
-interfaces. To reiterate:
-
- The cpu may touch the buffer before pci_dac_page_to_dma.
- The device may touch the buffer after pci_dac_page_to_dma
- is made, but the cpu may NOT.
-
-When the DMA transfer is complete, invoke:
-
- void pci_dac_dma_sync_single_for_cpu(struct pci_dev *pdev,
- dma64_addr_t dma_addr,
- size_t len, int direction);
-
-This must be done before the CPU looks at the buffer again.
-This interface behaves identically to pci_dma_sync_{single,sg}_for_cpu().
-
-And likewise, if you wish to let the device get back at the buffer after
-the cpu has read/written it, invoke:
-
- void pci_dac_dma_sync_single_for_device(struct pci_dev *pdev,
- dma64_addr_t dma_addr,
- size_t len, int direction);
-
-before letting the device access the DMA area again.
-
-If you need to get back to the PAGE/OFFSET tuple from a dma64_addr_t
-the following interfaces are provided:
-
- struct page *pci_dac_dma_to_page(struct pci_dev *pdev,
- dma64_addr_t dma_addr);
- unsigned long pci_dac_dma_to_offset(struct pci_dev *pdev,
- dma64_addr_t dma_addr);
-
-This is possible with the DAC interfaces purely because they are
-not translated in any way.
-
Optimizing Unmap State Space Consumption
On many platforms, pci_unmap_{single,page}() is simply a nop.

+ I<superscript>2</superscript>C (or without fancy typography, "I2C")
+ is an acronym for the "Inter-IC" bus, a simple bus protocol which is
+ widely used where low data rate communications suffice.
+ Since it's also a licensed trademark, some vendors use another
+ name (such as "Two-Wire Interface", TWI) for the same bus.
+ I2C only needs two signals (SCL for clock, SDA for data), conserving
+ board real estate and minimizing signal quality issues.
+ Most I2C devices use seven bit addresses, and bus speeds of up
+ to 400 kHz; there's a high speed extension (3.4 MHz) that's not yet
+ found wide use.
+ I2C is a multi-master bus; open drain signaling is used to
+ arbitrate between masters, as well as to handshake and to
+ synchronize clocks from slower clients.
+ </para>
+
+ <para>
+ The Linux I2C programming interfaces support only the master
+ side of bus interactions, not the slave side.
+ The programming interface is structured around two kinds of driver,
+ and two kinds of device.
+ An I2C "Adapter Driver" abstracts the controller hardware; it binds
+ to a physical device (perhaps a PCI device or platform_device) and
+ exposes a <structname>struct i2c_adapter</structname> representing
+ each I2C bus segment it manages.
+ On each I2C bus segment will be I2C devices represented by a
+ <structname>struct i2c_client</structname>. Those devices will
+ be bound to a <structname>struct i2c_driver</structname>,
+ which should follow the standard Linux driver model.
+ (At this writing, a legacy model is more widely used.)
+ There are functions to perform various I2C protocol operations; at
+ this writing all such functions are usable only from task context.
+ </para>
+
+ <para>
+ The System Management Bus (SMBus) is a sibling protocol. Most SMBus
+ systems are also I2C conformant. The electrical constraints are
+ tighter for SMBus, and it standardizes particular protocol messages
+ and idioms. Controllers that support I2C can also support most
+ SMBus operations, but SMBus controllers don't support all the protocol
+ options that an I2C controller will.
+ There are functions to perform various SMBus protocol operations,
+ either using I2C primitives or by issuing SMBus commands to
+ i2c_adapter devices which don't support those I2C operations.

+ SM501 Driver
+ ============
+
+Copyright 2006, 2007 Simtec Electronics
+
+Core
+----
+
+The core driver in drivers/mfd provides common services for the
+drivers which manage the specific hardware blocks. These services
+include locking for common registers, clock control and resource
+management.
+
+The core registers drivers for both PCI and generic bus based
+chips via the platform device and driver system.
+
+On detection of a device, the core initialises the chip (which may
+be specified by the platform data) and then exports the selected
+peripheral set as platform devices for the specific drivers.
+
+The core re-uses the platform device system as the platform device
+system provides enough features to support the drivers without the
+need to create a new bus-type and the associated code to go with it.
+
+
+Resources
+---------
+
+Each peripheral has a view of the device which is implicitly narrowed to
+the specific set of resources that peripheral requires in order to
+function correctly.
+
+The centralised memory allocation allows the driver to ensure that the
+maximum possible resource allocation can be made to the video subsystem
+as this is by-far the most resource-sensitive of the on-chip functions.
+
+The primary issue with memory allocation is that of moving the video
+buffers once a display mode is chosen. Indeed when a video mode change
+occurs the memory footprint of the video subsystem changes.
+
+Since video memory is difficult to move without changing the display
+(unless sufficient contiguous memory can be provided for the old and new
+modes simultaneously) the video driver fully utilises the memory area
+given to it by aligning fb0 to the start of the area and fb1 to the end
+of it. Any memory left over in the middle is used for the acceleration
+functions, which are transient and thus their location is less critical
+as it can be moved.
+
+
+Configuration
+-------------
+
+The platform device driver uses a set of platform data to pass
+configurations through to the core and the subsidiary drivers
+so that there can be support for more than one system carrying
+an SM501 built into a single kernel image.
+
+The PCI driver assumes that the PCI card behaves as per the Silicon
+Motion reference design.
+
+There is an errata (AB-5) affecting the selection of the
+of the M1XCLK and M1CLK frequencies. These two clocks
+must be sourced from the same PLL, although they can then
+be divided down individually. If this is not set, then SM501 may
+lock and hang the whole system. The driver will refuse to
+attach if the PLL selection is different.

+ http://blackfin.uclinux.org/tracker/index.php?func=detail&aid=544&group_id=18&atid=145
+ The GDB client for Blackfin uClinux causes incorrect values of local
+ variables to be displayed when the user breaks the running of kernel in GDB.
+2. Because of a hardware bug in Blackfin 533 v1.0.3:
+ 05000067 - Watchpoints (Hardware Breakpoints) are not supported
+ Hardware breakpoints cannot be set properly.
+
+
+Debug over Ethernet:
+
+1. Compile and install the cross platform version of gdb for blackfin, which
+ can be found at $(BINROOT)/bfin-elf-gdb.
+
+2. Apply this patch to the 2.6.x kernel. Select the menuconfig option under
+ "Kernel hacking" -> "Kernel debugging" -> "KGDB: kernel debug with remote gdb".
+ With this selected, option "Full Symbolic/Source Debugging support" and
+ "Compile the kernel with frame pointers" are also selected.
+
+3. Select option "KGDB: connect over (Ethernet)". Add "kgdboe=@target-IP/,@host-IP/" to
+ the option "Compiled-in Kernel Boot Parameter" under "Kernel hacking".
+
+4. Connect minicom to the serial port and boot the kernel image.
+
+5. Configure the IP "/> ifconfig eth0 target-IP"
+
+6. Start GDB client "bfin-elf-gdb vmlinux".
+
+7. Connect to the target "(gdb) target remote udp:target-IP:6443".
+
+8. Set software breakpoint "(gdb) break sys_open".
+
+9. Continue "(gdb) c".
+
+10. Run ls in the target console "/> ls".
+
+11. Breakpoint hits. "Breakpoint 1: sys_open(..."
+
+12. Display local variables and function paramters.
+ (*) This operation gives wrong results, see known issue 1.
+
+13. Single stepping "(gdb) si".
+
+14. Remove breakpoint 1. "(gdb) del 1"
+
+15. Set hardware breakpoint "(gdb) hbreak sys_open".
+
+16. Continue "(gdb) c".
+
+17. Run ls in the target console "/> ls".
+
+18. Hardware breakpoint hits. "Breakpoint 1: sys_open(...".
+ (*) This hardware breakpoint will not be hit, see known issue 2.
+
+19. Continue "(gdb) c".
+
+20. Interrupt the target in GDB "Ctrl+C".
+
+21. Detach from the target "(gdb) detach".
+
+22. Exit GDB "(gdb) quit".
+
+
+Debug over the UART:
+
+1. Compile and install the cross platform version of gdb for blackfin, which
+ can be found at $(BINROOT)/bfin-elf-gdb.
+
+2. Apply this patch to the 2.6.x kernel. Select the menuconfig option under
+ "Kernel hacking" -> "Kernel debugging" -> "KGDB: kernel debug with remote gdb".
+ With this selected, option "Full Symbolic/Source Debugging support" and
+ "Compile the kernel with frame pointers" are also selected.
+
+3. Select option "KGDB: connect over (UART)". Set "KGDB: UART port number" to be
+ a different one from the console. Don't forget to change the mode of
+ blackfin serial driver to PIO. Otherwise kgdb works incorrectly on UART.
+
+4. If you want connect to kgdb when the kernel boots, enable
+ "KGDB: Wait for gdb connection early"
+
+5. Compile kernel.
+
+6. Connect minicom to the serial port of the console and boot the kernel image.
+
+7. Start GDB client "bfin-elf-gdb vmlinux".
+
+8. Set the baud rate in GDB "(gdb) set remotebaud 57600".
+
+9. Connect to the target on the second serial port "(gdb) target remote /dev/ttyS1".
+
+10. Set software breakpoint "(gdb) break sys_open".
+
+11. Continue "(gdb) c".
+
+12. Run ls in the target console "/> ls".
+
+13. A breakpoint is hit. "Breakpoint 1: sys_open(..."
+
+14. All other operations are the same as that in KGDB over Ethernet.
+
+
+Debug over the same UART as console:
+
+1. Compile and install the cross platform version of gdb for blackfin, which
+ can be found at $(BINROOT)/bfin-elf-gdb.
+
+2. Apply this patch to the 2.6.x kernel. Select the menuconfig option under
+ "Kernel hacking" -> "Kernel debugging" -> "KGDB: kernel debug with remote gdb".
+ With this selected, option "Full Symbolic/Source Debugging support" and
+ "Compile the kernel with frame pointers" are also selected.
+
+3. Select option "KGDB: connect over UART". Set "KGDB: UART port number" to console.
+ Don't forget to change the mode of blackfin serial driver to PIO.
+ Otherwise kgdb works incorrectly on UART.
+
+4. If you want connect to kgdb when the kernel boots, enable
+ "KGDB: Wait for gdb connection early"
+
+5. Connect minicom to the serial port and boot the kernel image.
+
+6. (Optional) Ask target to wait for gdb connection by entering Ctrl+A. In minicom, you should enter Ctrl+A+A.
+
+7. Start GDB client "bfin-elf-gdb vmlinux".
+
+8. Set the baud rate in GDB "(gdb) set remotebaud 57600".
+
+9. Connect to the target "(gdb) target remote /dev/ttyS0".
+
+10. Set software breakpoint "(gdb) break sys_open".
+
+11. Continue "(gdb) c". Then enter Ctrl+C twice to stop GDB connection.
+
+12. Run ls in the target console "/> ls". Dummy string can be seen on the console.
+
+13. Then connect the gdb to target again. "(gdb) target remote /dev/ttyS0".
+ Now you will find a breakpoint is hit. "Breakpoint 1: sys_open(..."
+
+14. All other operations are the same as that in KGDB over Ethernet. The only
+ difference is that after continue command in GDB, please stop GDB
+ connection by 2 "Ctrl+C"s and connect again after breakpoints are hit or
+ Ctrl+A is entered.

+Legacy Drivers: Device Probing
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Some drivers are not fully converted to the driver model, because they take
+on a non-driver role: the driver registers its platform device, rather than
+leaving that for system infrastructure. Such drivers can't be hotplugged
+or coldplugged, since those mechanisms require device creation to be in a
+different system component than the driver.
+
+The only "good" reason for this is to handle older system designs which, like
+original IBM PCs, rely on error-prone "probe-the-hardware" models for hardware
+configuration. Newer systems have largely abandoned that model, in favor of
+bus-level support for dynamic configuration (PCI, USB), or device tables
+provided by the boot firmware (e.g. PNPACPI on x86). There are too many
+conflicting options about what might be where, and even educated guesses by
+an operating system will be wrong often enough to make trouble.
+
+This style of driver is discouraged. If you're updating such a driver,
+please try to move the device enumeration to a more appropriate location,
+outside the driver. This will usually be cleanup, since such drivers
+tend to already have "normal" modes, such as ones using device nodes that
+were created by PNP or by platform device setup.
+
+None the less, there are some APIs to support such legacy drivers. Avoid
+using these calls except with such hotplug-deficient drivers.
+
+ struct platform_device *platform_device_alloc(
+ char *name, unsigned id);
+
+You can use platform_device_alloc() to dynamically allocate a device, which
+you will then initialize with resources and platform_device_register().
+A better solution is usually:
+
+ struct platform_device *platform_device_register_simple(
+ char *name, unsigned id,
+ struct resource *res, unsigned nres);
+
+You can use platform_device_register_simple() as a one-step call to allocate
+and register a device.

Device Naming and Driver Binding

The platform_device.dev.bus_id is the canonical name for the devices.

+Kernel driver i2c-taos-evm
+
+Author: Jean Delvare <khali@linux-fr.org>
+
+This is a driver for the evaluation modules for TAOS I2C/SMBus chips.
+The modules include an SMBus master with limited capabilities, which can
+be controlled over the serial port. Virtually all evaluation modules
+are supported, but a few lines of code need to be added for each new
+module to instantiate the right I2C chip on the bus. Obviously, a driver
+for the chip in question is also needed.
+
+Currently supported devices are:
+
+* TAOS TSL2550 EVM
+
+For addtional information on TAOS products, please see
+ http://www.taosinc.com/
+
+
+Using this driver
+-----------------
+
+In order to use this driver, you'll need the serport driver, and the
+inputattach tool, which is part of the input-utils package. The following
+commands will tell the kernel that you have a TAOS EVM on the first
+serial port:
+
+# modprobe serport
+# inputattach --taos-evm /dev/ttyS0
+
+
+Technical details
+-----------------
+
+Only 4 SMBus transaction types are supported by the TAOS evaluation
+modules:
+* Receive Byte
+* Send Byte
+* Read Byte
+* Write Byte
+
+The communication protocol is text-based and pretty simple. It is
+described in a PDF document on the CD which comes with the evaluation
+module. The communication is rather slow, because the serial port has
+to operate at 1200 bps. However, I don't think this is a big concern in
+practice, as these modules are meant for evaluation and testing only.

-Kernel driver x1205
-===================
-
-Supported chips:
- * Xicor X1205 RTC
- Prefix: 'x1205'
- Addresses scanned: none
- Datasheet: http://www.intersil.com/cda/deviceinfo/0,1477,X1205,00.html
-
-Authors:
- Karen Spearel <kas11@tampabay.rr.com>,
- Alessandro Zummo <a.zummo@towertech.it>
-
-Description
------------
-
-This module aims to provide complete access to the Xicor X1205 RTC.
-Recently Xicor has merged with Intersil, but the chip is
-still sold under the Xicor brand.
-
-This chip is located at address 0x6f and uses a 2-byte register addressing.
-Two bytes need to be written to read a single register, while most
-other chips just require one and take the second one as the data
-to be written. To prevent corrupting unknown chips, the user must
-explicitely set the probe parameter.
-
-example:
-
-modprobe x1205 probe=0,0x6f
-
-The module supports one more option, hctosys, which is used to set the
-software clock from the x1205. On systems where the x1205 is the
-only hardware rtc, this parameter could be used to achieve a correct
-date/time earlier in the system boot sequence.
-
-example:
-
-modprobe x1205 probe=0,0x6f hctosys=1

+This brief document describes how to use the kernel's PPPoL2TP driver
+to provide L2TP functionality. L2TP is a protocol that tunnels one or
+more PPP sessions over a UDP tunnel. It is commonly used for VPNs
+(L2TP/IPSec) and by ISPs to tunnel subscriber PPP sessions over an IP
+network infrastructure.
+
+Design
+======
+
+The PPPoL2TP driver, drivers/net/pppol2tp.c, provides a mechanism by
+which PPP frames carried through an L2TP session are passed through
+the kernel's PPP subsystem. The standard PPP daemon, pppd, handles all
+PPP interaction with the peer. PPP network interfaces are created for
+each local PPP endpoint.
+
+The L2TP protocol http://www.faqs.org/rfcs/rfc2661.html defines L2TP
+control and data frames. L2TP control frames carry messages between
+L2TP clients/servers and are used to setup / teardown tunnels and
+sessions. An L2TP client or server is implemented in userspace and
+will use a regular UDP socket per tunnel. L2TP data frames carry PPP
+frames, which may be PPP control or PPP data. The kernel's PPP
+subsystem arranges for PPP control frames to be delivered to pppd,
+while data frames are forwarded as usual.
+
+Each tunnel and session within a tunnel is assigned a unique tunnel_id
+and session_id. These ids are carried in the L2TP header of every
+control and data packet. The pppol2tp driver uses them to lookup
+internal tunnel and/or session contexts. Zero tunnel / session ids are
+treated specially - zero ids are never assigned to tunnels or sessions
+in the network. In the driver, the tunnel context keeps a pointer to
+the tunnel UDP socket. The session context keeps a pointer to the
+PPPoL2TP socket, as well as other data that lets the driver interface
+to the kernel PPP subsystem.
+
+Note that the pppol2tp kernel driver handles only L2TP data frames;
+L2TP control frames are simply passed up to userspace in the UDP
+tunnel socket. The kernel handles all datapath aspects of the
+protocol, including data packet resequencing (if enabled).
+
+There are a number of requirements on the userspace L2TP daemon in
+order to use the pppol2tp driver.
+
+1. Use a UDP socket per tunnel.
+
+2. Create a single PPPoL2TP socket per tunnel bound to a special null
+ session id. This is used only for communicating with the driver but
+ must remain open while the tunnel is active. Opening this tunnel
+ management socket causes the driver to mark the tunnel socket as an
+ L2TP UDP encapsulation socket and flags it for use by the
+ referenced tunnel id. This hooks up the UDP receive path via
+ udp_encap_rcv() in net/ipv4/udp.c. PPP data frames are never passed
+ in this special PPPoX socket.
+
+3. Create a PPPoL2TP socket per L2TP session. This is typically done
+ by starting pppd with the pppol2tp plugin and appropriate
+ arguments. A PPPoL2TP tunnel management socket (Step 2) must be
+ created before the first PPPoL2TP session socket is created.
+
+When creating PPPoL2TP sockets, the application provides information
+to the driver about the socket in a socket connect() call. Source and
+destination tunnel and session ids are provided, as well as the file
+descriptor of a UDP socket. See struct pppol2tp_addr in
+include/linux/if_ppp.h. Note that zero tunnel / session ids are
+treated specially. When creating the per-tunnel PPPoL2TP management
+socket in Step 2 above, zero source and destination session ids are
+specified, which tells the driver to prepare the supplied UDP file
+descriptor for use as an L2TP tunnel socket.
+
+Userspace may control behavior of the tunnel or session using
+setsockopt and ioctl on the PPPoX socket. The following socket
+options are supported:-
+
+DEBUG - bitmask of debug message categories. See below.
+SENDSEQ - 0 => don't send packets with sequence numbers
+ 1 => send packets with sequence numbers
+RECVSEQ - 0 => receive packet sequence numbers are optional
+ 1 => drop receive packets without sequence numbers
+LNSMODE - 0 => act as LAC.
+ 1 => act as LNS.
+REORDERTO - reorder timeout (in millisecs). If 0, don't try to reorder.
+
+Only the DEBUG option is supported by the special tunnel management
+PPPoX socket.
+
+In addition to the standard PPP ioctls, a PPPIOCGL2TPSTATS is provided
+to retrieve tunnel and session statistics from the kernel using the
+PPPoX socket of the appropriate tunnel or session.
+
+Debugging
+=========
+
+The driver supports a flexible debug scheme where kernel trace
+messages may be optionally enabled per tunnel and per session. Care is
+needed when debugging a live system since the messages are not
+rate-limited and a busy system could be swamped. Userspace uses
+setsockopt on the PPPoX socket to set a debug mask.
+
+The following debug mask bits are available:
+
+PPPOL2TP_MSG_DEBUG verbose debug (if compiled in)
+PPPOL2TP_MSG_CONTROL userspace - kernel interface
+PPPOL2TP_MSG_SEQ sequence numbers handling
+PPPOL2TP_MSG_DATA data packets
+

+============
+
+The PPPoL2TP driver was developed as part of the OpenL2TP project by
+Katalix Systems Ltd. OpenL2TP is a full-featured L2TP client / server,
+designed from the ground up to have the L2TP datapath in the
+kernel. The project also implemented the pppol2tp plugin for pppd
+which allows pppd to use the kernel driver. Details can be found at
+http://openl2tp.sourceforge.net.

+How to use packet injection with mac80211
+=========================================
+
+mac80211 now allows arbitrary packets to be injected down any Monitor Mode
+interface from userland. The packet you inject needs to be composed in the
+following format:
+
+ [ radiotap header ]
+ [ ieee80211 header ]
+ [ payload ]
+
+The radiotap format is discussed in
+./Documentation/networking/radiotap-headers.txt.
+
+Despite 13 radiotap argument types are currently defined, most only make sense
+to appear on received packets. Currently three kinds of argument are used by
+the injection code, although it knows to skip any other arguments that are
+present (facilitating replay of captured radiotap headers directly):
+
+ - IEEE80211_RADIOTAP_RATE - u8 arg in 500kbps units (0x02 --> 1Mbps)
+
+ - IEEE80211_RADIOTAP_ANTENNA - u8 arg, 0x00 = ant1, 0x01 = ant2
+
+ - IEEE80211_RADIOTAP_DBM_TX_POWER - u8 arg, dBm
+
+Here is an example valid radiotap header defining these three parameters
+
+ 0x00, 0x00, // <-- radiotap version
+ 0x0b, 0x00, // <- radiotap header length
+ 0x04, 0x0c, 0x00, 0x00, // <-- bitmap
+ 0x6c, // <-- rate
+ 0x0c, //<-- tx power
+ 0x01 //<-- antenna
+
+The ieee80211 header follows immediately afterwards, looking for example like

+ HOWTO for multiqueue network device support
+ ===========================================
+
+Section 1: Base driver requirements for implementing multiqueue support
+Section 2: Qdisc support for multiqueue devices
+Section 3: Brief howto using PRIO or RR for multiqueue devices
+
+
+Intro: Kernel support for multiqueue devices
+---------------------------------------------------------
+
+Kernel support for multiqueue devices is only an API that is presented to the
+netdevice layer for base drivers to implement. This feature is part of the
+core networking stack, and all network devices will be running on the
+multiqueue-aware stack. If a base driver only has one queue, then these
+changes are transparent to that driver.
+
+
+Section 1: Base driver requirements for implementing multiqueue support
+-----------------------------------------------------------------------
+
+Base drivers are required to use the new alloc_etherdev_mq() or
+alloc_netdev_mq() functions to allocate the subqueues for the device. The
+underlying kernel API will take care of the allocation and deallocation of
+the subqueue memory, as well as netdev configuration of where the queues
+exist in memory.
+
+The base driver will also need to manage the queues as it does the global
+netdev->queue_lock today. Therefore base drivers should use the
+netif_{start|stop|wake}_subqueue() functions to manage each queue while the
+device is still operational. netdev->queue_lock is still used when the device
+comes online or when it's completely shut down (unregister_netdev(), etc.).
+
+Finally, the base driver should indicate that it is a multiqueue device. The
+feature flag NETIF_F_MULTI_QUEUE should be added to the netdev->features
+bitmap on device initialization. Below is an example from e1000:
+
+#ifdef CONFIG_E1000_MQ
+ if ( (adapter->hw.mac.type == e1000_82571) ||
+ (adapter->hw.mac.type == e1000_82572) ||
+ (adapter->hw.mac.type == e1000_80003es2lan))
+ netdev->features |= NETIF_F_MULTI_QUEUE;
+#endif
+
+
+Section 2: Qdisc support for multiqueue devices
+-----------------------------------------------
+
+Currently two qdiscs support multiqueue devices. A new round-robin qdisc,
+sch_rr, and sch_prio. The qdisc is responsible for classifying the skb's to
+bands and queues, and will store the queue mapping into skb->queue_mapping.
+Use this field in the base driver to determine which queue to send the skb
+to.
+
+sch_rr has been added for hardware that doesn't want scheduling policies from
+software, so it's a straight round-robin qdisc. It uses the same syntax and
+classification priomap that sch_prio uses, so it should be intuitive to
+configure for people who've used sch_prio.
+
+The PRIO qdisc naturally plugs into a multiqueue device. If PRIO has been
+built with NET_SCH_PRIO_MQ, then upon load, it will make sure the number of
+bands requested is equal to the number of queues on the hardware. If they
+are equal, it sets a one-to-one mapping up between the queues and bands. If
+they're not equal, it will not load the qdisc. This is the same behavior
+for RR. Once the association is made, any skb that is classified will have
+skb->queue_mapping set, which will allow the driver to properly queue skb's
+to multiple queues.
+
+
+Section 3: Brief howto using PRIO and RR for multiqueue devices
+---------------------------------------------------------------
+
+The userspace command 'tc,' part of the iproute2 package, is used to configure
+qdiscs. To add the PRIO qdisc to your network device, assuming the device is
+called eth0, run the following command:
+
+# tc qdisc add dev eth0 root handle 1: prio bands 4 multiqueue
+
+This will create 4 bands, 0 being highest priority, and associate those bands
+to the queues on your NIC. Assuming eth0 has 4 Tx queues, the band mapping
+would look like:
+
+band 0 => queue 0
+band 1 => queue 1
+band 2 => queue 2
+band 3 => queue 3
+
+Traffic will begin flowing through each queue if your TOS values are assigning
+traffic across the various bands. For example, ssh traffic will always try to
+go out band 0 based on TOS -> Linux priority conversion (realtime traffic),
+so it will be sent out queue 0. ICMP traffic (pings) fall into the "normal"
+traffic classification, which is band 1. Therefore pings will be send out
+queue 1 on the NIC.
+
+Note the use of the multiqueue keyword. This is only in versions of iproute2
+that support multiqueue networking devices; if this is omitted when loading
+a qdisc onto a multiqueue device, the qdisc will load and operate the same
+if it were loaded onto a single-queue device (i.e. - sends all traffic to
+queue 0).
+
+Another alternative to multiqueue band allocation can be done by using the
+multiqueue option and specify 0 bands. If this is the case, the qdisc will
+allocate the number of bands to equal the number of queues that the device
+reports, and bring the qdisc online.
+
+The behavior of tc filters remains the same, where it will override TOS priority
+classification.

+MTU
+===
+Each network device has a Maximum Transfer Unit. The MTU does not
+include any link layer protocol overhead. Upper layer protocols must
+not pass a socket buffer (skb) to a device to transmit with more data
+than the mtu. The MTU does not include link layer header overhead, so
+for example on Ethernet if the standard MTU is 1500 bytes used, the
+actual skb will contain up to 1514 bytes because of the Ethernet
+header. Devices should allow for the 4 byte VLAN header as well.
+
+Segmentation Offload (GSO, TSO) is an exception to this rule. The
+upper layer protocol may pass a large socket buffer to the device
+transmit routine, and the device will break that up into separate
+packets based on the current MTU.
+
+MTU is symmetrical and applies both to receive and transmit. A device
+must be able to receive at least the maximum size packet allowed by
+the MTU. A network device may use the MTU as mechanism to size receive
+buffers, but the device should allow packets with VLAN header. With
+standard Ethernet mtu of 1500 bytes, the device should allow up to
+1518 byte packets (1500 + 14 header + 4 tag). The device may either:

+How to use radiotap headers
+===========================
+
+Pointer to the radiotap include file
+------------------------------------
+
+Radiotap headers are variable-length and extensible, you can get most of the
+information you need to know on them from:
+
+./include/net/ieee80211_radiotap.h
+
+This document gives an overview and warns on some corner cases.
+
+
+Structure of the header
+-----------------------
+
+There is a fixed portion at the start which contains a u32 bitmap that defines
+if the possible argument associated with that bit is present or not. So if b0
+of the it_present member of ieee80211_radiotap_header is set, it means that
+the header for argument index 0 (IEEE80211_RADIOTAP_TSFT) is present in the
+argument area.
+
+ < 8-byte ieee80211_radiotap_header >
+ [ <possible argument bitmap extensions ... > ]
+ [ <argument> ... ]
+
+At the moment there are only 13 possible argument indexes defined, but in case
+we run out of space in the u32 it_present member, it is defined that b31 set
+indicates that there is another u32 bitmap following (shown as "possible
+argument bitmap extensions..." above), and the start of the arguments is moved
+forward 4 bytes each time.
+
+Note also that the it_len member __le16 is set to the total number of bytes
+covered by the ieee80211_radiotap_header and any arguments following.
+
+
+Requirements for arguments
+--------------------------
+
+After the fixed part of the header, the arguments follow for each argument
+index whose matching bit is set in the it_present member of
+ieee80211_radiotap_header.
+
+ - the arguments are all stored little-endian!
+
+ - the argument payload for a given argument index has a fixed size. So
+ IEEE80211_RADIOTAP_TSFT being present always indicates an 8-byte argument is
+ present. See the comments in ./include/net/ieee80211_radiotap.h for a nice
+ breakdown of all the argument sizes
+
+ - the arguments must be aligned to a boundary of the argument size using
+ padding. So a u16 argument must start on the next u16 boundary if it isn't
+ already on one, a u32 must start on the next u32 boundary and so on.
+
+ - "alignment" is relative to the start of the ieee80211_radiotap_header, ie,
+ the first byte of the radiotap header. The absolute alignment of that first
+ byte isn't defined. So even if the whole radiotap header is starting at, eg,
+ address 0x00000003, still the first byte of the radiotap header is treated as
+ 0 for alignment purposes.
+
+ - the above point that there may be no absolute alignment for multibyte
+ entities in the fixed radiotap header or the argument region means that you
+ have to take special evasive action when trying to access these multibyte
+ entities. Some arches like Blackfin cannot deal with an attempt to
+ dereference, eg, a u16 pointer that is pointing to an odd address. Instead
+ you have to use a kernel API get_unaligned() to dereference the pointer,
+ which will do it bytewise on the arches that require that.
+
+ - The arguments for a given argument index can be a compound of multiple types
+ together. For example IEEE80211_RADIOTAP_CHANNEL has an argument payload
+ consisting of two u16s of total length 4. When this happens, the padding
+ rule is applied dealing with a u16, NOT dealing with a 4-byte single entity.
+
+
+Example valid radiotap header
+-----------------------------
+
+ 0x00, 0x00, // <-- radiotap version + pad byte
+ 0x0b, 0x00, // <- radiotap header length
+ 0x04, 0x0c, 0x00, 0x00, // <-- bitmap
+ 0x6c, // <-- rate (in 500kHz units)
+ 0x0c, //<-- tx power
+ 0x01 //<-- antenna
+
+
+Using the Radiotap Parser
+-------------------------
+
+If you are having to parse a radiotap struct, you can radically simplify the
+job by using the radiotap parser that lives in net/wireless/radiotap.c and has
+its prototypes available in include/net/cfg80211.h. You use it like this:
+
+#include <net/cfg80211.h>
+
+/* buf points to the start of the radiotap header part */
+
+int MyFunction(u8 * buf, int buflen)
+{
+ int pkt_rate_100kHz = 0, antenna = 0, pwr = 0;
+ struct ieee80211_radiotap_iterator iterator;
+ int ret = ieee80211_radiotap_iterator_init(&iterator, buf, buflen);
+
+ while (!ret) {
+
+ ret = ieee80211_radiotap_iterator_next(&iterator);
+
+ if (ret)
+ continue;
+
+ /* see if this argument is something we can use */
+
+ switch (iterator.this_arg_index) {
+ /*
+ * You must take care when dereferencing iterator.this_arg
+ * for multibyte types... the pointer is not aligned. Use
+ * get_unaligned((type *)iterator.this_arg) to dereference
+ * iterator.this_arg for type "type" safely on all arches.
+ */
+ case IEEE80211_RADIOTAP_RATE:
+ /* radiotap "rate" u8 is in
+ * 500kbps units, eg, 0x02=1Mbps
+ */
+ pkt_rate_100kHz = (*iterator.this_arg) * 5;
+ break;
+
+ case IEEE80211_RADIOTAP_ANTENNA:
+ /* radiotap uses 0 for 1st ant */
+ antenna = *iterator.this_arg);
+ break;
+
+ case IEEE80211_RADIOTAP_DBM_TX_POWER:
+ pwr = *iterator.this_arg;
+ break;
+
+ default:
+ break;
+ }
+ } /* while more rt headers */
+
+ if (ret != -ENOENT)
+ return TXRX_DROP;
+
+ /* discard the radiotap header part */
+ buf += iterator.max_length;
+ buflen -= iterator.max_length;

-1 Overview
-===========
-
-The sk98lin driver supports the Marvell Yukon and SysKonnect
-SK-98xx/SK-95xx compliant Gigabit Ethernet Adapter on Linux. It has
-been tested with Linux on Intel/x86 machines.
-***
-
-
-2 Required Files
-=================
-
-The linux kernel source.
-No additional files required.
-***
-
-
-3 Installation
-===============
-
-It is recommended to download the latest version of the driver from the
-SysKonnect web site www.syskonnect.com. If you have downloaded the latest
-driver, the Linux kernel has to be patched before the driver can be
-installed. For details on how to patch a Linux kernel, refer to the
-patch.txt file.
-
-3.1 Driver Installation
-------------------------
-
-The following steps describe the actions that are required to install
-the driver and to start it manually. These steps should be carried
-out for the initial driver setup. Once confirmed to be ok, they can
-be included in the system start.
-
-NOTE 1: To perform the following tasks you need 'root' access.
-
-NOTE 2: In case of problems, please read the section "Troubleshooting"
- below.
-
-The driver can either be integrated into the kernel or it can be compiled
-as a module. Select the appropriate option during the kernel
-configuration.
-
-Compile/use the driver as a module
-----------------------------------
-To compile the driver, go to the directory /usr/src/linux and
-execute the command "make menuconfig" or "make xconfig" and proceed as
-follows:
-
-To integrate the driver permanently into the kernel, proceed as follows:
-
-1. Select the menu "Network device support" and then "Ethernet(1000Mbit)"
-2. Mark "Marvell Yukon Chipset / SysKonnect SK-98xx family support"
- with (*)
-3. Build a new kernel when the configuration of the above options is
- finished.
-4. Install the new kernel.
-5. Reboot your system.
-
-To use the driver as a module, proceed as follows:
-
-1. Enable 'loadable module support' in the kernel.
-2. For automatic driver start, enable the 'Kernel module loader'.
-3. Select the menu "Network device support" and then "Ethernet(1000Mbit)"
-4. Mark "Marvell Yukon Chipset / SysKonnect SK-98xx family support"
- with (M)
-5. Execute the command "make modules".
-6. Execute the command "make modules_install".
- The appropriate modules will be installed.
-7. Reboot your system.
-
-
-Load the module manually
-------------------------
-To load the module manually, proceed as follows:
-
-1. Enter "modprobe sk98lin".
-2. If a Marvell Yukon or SysKonnect SK-98xx adapter is installed in
- your computer and you have a /proc file system, execute the command:
- "ls /proc/net/sk98lin/"
- This should produce an output containing a line with the following
- format:
- eth0 eth1 ...
- which indicates that your adapter has been found and initialized.
-
- NOTE 1: If you have more than one Marvell Yukon or SysKonnect SK-98xx
- adapter installed, the adapters will be listed as 'eth0',
- 'eth1', 'eth2', etc.
- For each adapter, repeat steps 3 and 4 below.
-
- NOTE 2: If you have other Ethernet adapters installed, your Marvell
- Yukon or SysKonnect SK-98xx adapter will be mapped to the
- next available number, e.g. 'eth1'. The mapping is executed
- automatically.
- The module installation message (displayed either in a system
- log file or on the console) prints a line for each adapter
- found containing the corresponding 'ethX'.
-
-3. Select an IP address and assign it to the respective adapter by
- entering:
- ifconfig eth0 <ip-address>
- With this command, the adapter is connected to the Ethernet.
-
- SK-98xx Gigabit Ethernet Server Adapters: The yellow LED on the adapter
- is now active, the link status LED of the primary port is active and
- the link status LED of the secondary port (on dual port adapters) is
- blinking (if the ports are connected to a switch or hub).
- SK-98xx V2.0 Gigabit Ethernet Adapters: The link status LED is active.
- In addition, you will receive a status message on the console stating
- "ethX: network connection up using port Y" and showing the selected
- connection parameters (x stands for the ethernet device number
- (0,1,2, etc), y stands for the port name (A or B)).
-
- NOTE: If you are in doubt about IP addresses, ask your network
- administrator for assistance.
-
-4. Your adapter should now be fully operational.
- Use 'ping <otherstation>' to verify the connection to other computers
- on your network.
-5. To check the adapter configuration view /proc/net/sk98lin/[devicename].
- For example by executing:
- "cat /proc/net/sk98lin/eth0"
-
-Unload the module
------------------
-To stop and unload the driver modules, proceed as follows:
-
-1. Execute the command "ifconfig eth0 down".
-2. Execute the command "rmmod sk98lin".
-
-3.2 Inclusion of adapter at system start
------------------------------------------
-
-Since a large number of different Linux distributions are
-available, we are unable to describe a general installation procedure
-for the driver module.
-Because the driver is now integrated in the kernel, installation should
-be easy, using the standard mechanism of your distribution.
-Refer to the distribution's manual for installation of ethernet adapters.
-
-***
-
-4 Driver Parameters
-====================
-
-Parameters can be set at the command line after the module has been
-loaded with the command 'modprobe'.
-In some distributions, the configuration tools are able to pass parameters
-to the driver module.
-
-If you use the kernel module loader, you can set driver parameters
-in the file /etc/modprobe.conf (or /etc/modules.conf in 2.4 or earlier).
-To set the driver parameters in this file, proceed as follows:
-
-1. Insert a line of the form :
- options sk98lin ...
- For "...", the same syntax is required as described for the command
- line parameters of modprobe below.
-2. To activate the new parameters, either reboot your computer
- or
- unload and reload the driver.
- The syntax of the driver parameters is:
-
- modprobe sk98lin parameter=value1[,value2[,value3...]]
-
- where value1 refers to the first adapter, value2 to the second etc.
-
-NOTE: All parameters are case sensitive. Write them exactly as shown
- below.
-
-Example:
-Suppose you have two adapters. You want to set auto-negotiation
-on the first adapter to ON and on the second adapter to OFF.
-You also want to set DuplexCapabilities on the first adapter
-to FULL, and on the second adapter to HALF.
-Then, you must enter:
-
- modprobe sk98lin AutoNeg_A=On,Off DupCap_A=Full,Half
-
-NOTE: The number of adapters that can be configured this way is
- limited in the driver (file skge.c, constant SK_MAX_CARD_PARAM).
- The current limit is 16. If you happen to install
- more adapters, adjust this and recompile.
-
-
-4.1 Per-Port Parameters
-------------------------
-
-These settings are available for each port on the adapter.
-In the following description, '?' stands for the port for
-which you set the parameter (A or B).
-
-Speed
------
-Parameter: Speed_?
-Values: 10, 100, 1000, Auto
-Default: Auto
-
-This parameter is used to set the speed capabilities. It is only valid
-for the SK-98xx V2.0 copper adapters.
-Usually, the speed is negotiated between the two ports during link
-establishment. If this fails, a port can be forced to a specific setting
-with this parameter.
-
-Auto-Negotiation
-----------------
-Parameter: AutoNeg_?
-Values: On, Off, Sense
-Default: On
-
-The "Sense"-mode automatically detects whether the link partner supports
-auto-negotiation or not.
-
-Duplex Capabilities
--------------------
-Parameter: DupCap_?
-Values: Half, Full, Both
-Default: Both
-
-This parameters is only relevant if auto-negotiation for this port is
-not set to "Sense". If auto-negotiation is set to "On", all three values
-are possible. If it is set to "Off", only "Full" and "Half" are allowed.
-This parameter is useful if your link partner does not support all
-possible combinations.
-
-Flow Control
-------------
-Parameter: FlowCtrl_?
-Values: Sym, SymOrRem, LocSend, None
-Default: SymOrRem
-
-This parameter can be used to set the flow control capabilities the
-port reports during auto-negotiation. It can be set for each port
-individually.
-Possible modes:
- -- Sym = Symmetric: both link partners are allowed to send
- PAUSE frames
- -- SymOrRem = SymmetricOrRemote: both or only remote partner
- are allowed to send PAUSE frames
- -- LocSend = LocalSend: only local link partner is allowed
- to send PAUSE frames
- -- None = no link partner is allowed to send PAUSE frames
-
-NOTE: This parameter is ignored if auto-negotiation is set to "Off".
-
-Role in Master-Slave-Negotiation (1000Base-T only)
---------------------------------------------------
-Parameter: Role_?
-Values: Auto, Master, Slave
-Default: Auto
-
-This parameter is only valid for the SK-9821 and SK-9822 adapters.
-For two 1000Base-T ports to communicate, one must take the role of the
-master (providing timing information), while the other must be the
-slave. Usually, this is negotiated between the two ports during link
-establishment. If this fails, a port can be forced to a specific setting
-with this parameter.
-
-
-4.2 Adapter Parameters
------------------------
-
-Connection Type (SK-98xx V2.0 copper adapters only)
----------------
-Parameter: ConType
-Values: Auto, 100FD, 100HD, 10FD, 10HD
-Default: Auto
-
-The parameter 'ConType' is a combination of all five per-port parameters
-within one single parameter. This simplifies the configuration of both ports
-of an adapter card! The different values of this variable reflect the most
-meaningful combinations of port parameters.
-
-The following table shows the values of 'ConType' and the corresponding
-combinations of the per-port parameters:
-
- ConType | DupCap AutoNeg FlowCtrl Role Speed
- ----------+------------------------------------------------------
- Auto | Both On SymOrRem Auto Auto
- 100FD | Full Off None Auto (ignored) 100
- 100HD | Half Off None Auto (ignored) 100
- 10FD | Full Off None Auto (ignored) 10
- 10HD | Half Off None Auto (ignored) 10
-
-Stating any other port parameter together with this 'ConType' variable
-will result in a merged configuration of those settings. This due to
-the fact, that the per-port parameters (e.g. Speed_? ) have a higher
-priority than the combined variable 'ConType'.
-
-NOTE: This parameter is always used on both ports of the adapter card.
-
-Interrupt Moderation
---------------------
-Parameter: Moderation
-Values: None, Static, Dynamic
-Default: None
-
-Interrupt moderation is employed to limit the maximum number of interrupts
-the driver has to serve. That is, one or more interrupts (which indicate any
-transmit or receive packet to be processed) are queued until the driver
-processes them. When queued interrupts are to be served, is determined by the
-'IntsPerSec' parameter, which is explained later below.
-
-Possible modes:
-
- -- None - No interrupt moderation is applied on the adapter card.
- Therefore, each transmit or receive interrupt is served immediately
- as soon as it appears on the interrupt line of the adapter card.
-
- -- Static - Interrupt moderation is applied on the adapter card.
- All transmit and receive interrupts are queued until a complete
- moderation interval ends. If such a moderation interval ends, all
- queued interrupts are processed in one big bunch without any delay.
- The term 'static' reflects the fact, that interrupt moderation is
- always enabled, regardless how much network load is currently
- passing via a particular interface. In addition, the duration of
- the moderation interval has a fixed length that never changes while
- the driver is operational.
-
- -- Dynamic - Interrupt moderation might be applied on the adapter card,
- depending on the load of the system. If the driver detects that the
- system load is too high, the driver tries to shield the system against
- too much network load by enabling interrupt moderation. If - at a later
- time - the CPU utilization decreases again (or if the network load is
- negligible) the interrupt moderation will automatically be disabled.
-
-Interrupt moderation should be used when the driver has to handle one or more
-interfaces with a high network load, which - as a consequence - leads also to a
-high CPU utilization. When moderation is applied in such high network load
-situations, CPU load might be reduced by 20-30%.
-
-NOTE: The drawback of using interrupt moderation is an increase of the round-
-trip-time (RTT), due to the queueing and serving of interrupts at dedicated
-moderation times.
-
-Interrupts per second
----------------------
-Parameter: IntsPerSec
-Values: 30...40000 (interrupts per second)
-Default: 2000
-
-This parameter is only used if either static or dynamic interrupt moderation
-is used on a network adapter card. Using this parameter if no moderation is
-applied will lead to no action performed.
-
-This parameter determines the length of any interrupt moderation interval.
-Assuming that static interrupt moderation is to be used, an 'IntsPerSec'
-parameter value of 2000 will lead to an interrupt moderation interval of
-500 microseconds.
-
-NOTE: The duration of the moderation interval is to be chosen with care.
-At first glance, selecting a very long duration (e.g. only 100 interrupts per
-second) seems to be meaningful, but the increase of packet-processing delay
-is tremendous. On the other hand, selecting a very short moderation time might
-compensate the use of any moderation being applied.
-
-
-Preferred Port
---------------
-Parameter: PrefPort
-Values: A, B
-Default: A
-
-This is used to force the preferred port to A or B (on dual-port network
-adapters). The preferred port is the one that is used if both are detected
-as fully functional.
-
-RLMT Mode (Redundant Link Management Technology)
-------------------------------------------------
-Parameter: RlmtMode
-Values: CheckLinkState,CheckLocalPort, CheckSeg, DualNet
-Default: CheckLinkState
-
-RLMT monitors the status of the port. If the link of the active port
-fails, RLMT switches immediately to the standby link. The virtual link is
-maintained as long as at least one 'physical' link is up.
-
-Possible modes:
-
- -- CheckLinkState - Check link state only: RLMT uses the link state
- reported by the adapter hardware for each individual port to
- determine whether a port can be used for all network traffic or
- not.
-
- -- CheckLocalPort - In this mode, RLMT monitors the network path
- between the two ports of an adapter by regularly exchanging packets
- between them. This mode requires a network configuration in which
- the two ports are able to "see" each other (i.e. there must not be
- any router between the ports).
-
- -- CheckSeg - Check local port and segmentation: This mode supports the
- same functions as the CheckLocalPort mode and additionally checks
- network segmentation between the ports. Therefore, this mode is only
- to be used if Gigabit Ethernet switches are installed on the network
- that have been configured to use the Spanning Tree protocol.
-
- -- DualNet - In this mode, ports A and B are used as separate devices.
- If you have a dual port adapter, port A will be configured as eth0
- and port B as eth1. Both ports can be used independently with
- distinct IP addresses. The preferred port setting is not used.
- RLMT is turned off.
-
-NOTE: RLMT modes CLP and CLPSS are designed to operate in configurations
- where a network path between the ports on one adapter exists.
- Moreover, they are not designed to work where adapters are connected
- back-to-back.

-
-5 Large Frame Support
-======================
-
-The driver supports large frames (also called jumbo frames). Using large
-frames can result in an improved throughput if transferring large amounts
-of data.
-To enable large frames, set the MTU (maximum transfer unit) of the
-interface to the desired value (up to 9000), execute the following
-command:
- ifconfig eth0 mtu 9000
-This will only work if you have two adapters connected back-to-back
-or if you use a switch that supports large frames. When using a switch,
-it should be configured to allow large frames and auto-negotiation should
-be set to OFF. The setting must be configured on all adapters that can be
-reached by the large frames. If one adapter is not set to receive large
-frames, it will simply drop them.
-
-You can switch back to the standard ethernet frame size by executing the
-following command:
- ifconfig eth0 mtu 1500
-
-To permanently configure this setting, add a script with the 'ifconfig'
-line to the system startup sequence (named something like "S99sk98lin"
-in /etc/rc.d/rc2.d).

-
-6 VLAN and Link Aggregation Support (IEEE 802.1, 802.1q, 802.3ad)
-==================================================================
-
-The Marvell Yukon/SysKonnect Linux drivers are able to support VLAN and
-Link Aggregation according to IEEE standards 802.1, 802.1q, and 802.3ad.
-These features are only available after installation of open source
-modules available on the Internet:
-For VLAN go to: http://www.candelatech.com/~greear/vlan.html
-For Link Aggregation go to: http://www.st.rim.or.jp/~yumo
-
-NOTE: SysKonnect GmbH does not offer any support for these open source
- modules and does not take the responsibility for any kind of
- failures or problems arising in connection with these modules.
-
-NOTE: Configuring Link Aggregation on a SysKonnect dual link adapter may
- cause problems when unloading the driver.
-
-
-7 Troubleshooting
-==================
-
-If any problems occur during the installation process, check the
-following list:
-
-
-Problem: The SK-98xx adapter cannot be found by the driver.
-Solution: In /proc/pci search for the following entry:
- 'Ethernet controller: SysKonnect SK-98xx ...'
- If this entry exists, the SK-98xx or SK-98xx V2.0 adapter has
- been found by the system and should be operational.
- If this entry does not exist or if the file '/proc/pci' is not
- found, there may be a hardware problem or the PCI support may
- not be enabled in your kernel.
- The adapter can be checked using the diagnostics program which
- is available on the SysKonnect web site:
- www.syskonnect.com
-
- Some COMPAQ machines have problems dealing with PCI under Linux.
- This problem is described in the 'PCI howto' document
- (included in some distributions or available from the
- web, e.g. at 'www.linux.org').
-
-
-Problem: Programs such as 'ifconfig' or 'route' cannot be found or the
- error message 'Operation not permitted' is displayed.
-Reason: You are not logged in as user 'root'.
-Solution: Logout and login as 'root' or change to 'root' via 'su'.
-
-
-Problem: Upon use of the command 'ping <address>' the message
- "ping: sendto: Network is unreachable" is displayed.
-Reason: Your route is not set correctly.
-Solution: If you are using RedHat, you probably forgot to set up the
- route in the 'network configuration'.
- Check the existing routes with the 'route' command and check
- if an entry for 'eth0' exists, and if so, if it is set correctly.
-
-
-Problem: The driver can be started, the adapter is connected to the
- network, but you cannot receive or transmit any packets;
- e.g. 'ping' does not work.
-Reason: There is an incorrect route in your routing table.
-Solution: Check the routing table with the command 'route' and read the
- manual help pages dealing with routes (enter 'man route').
-
-NOTE: Although the 2.2.x kernel versions generate the routing entry
- automatically, problems of this kind may occur here as well. We've
- come across a situation in which the driver started correctly at
- system start, but after the driver has been removed and reloaded,
- the route of the adapter's network pointed to the 'dummy0'device
- and had to be corrected manually.
-
-
-Problem: Your computer should act as a router between multiple
- IP subnetworks (using multiple adapters), but computers in
- other subnetworks cannot be reached.
-Reason: Either the router's kernel is not configured for IP forwarding
- or the routing table and gateway configuration of at least one
- computer is not working.
-
-Problem: Upon driver start, the following error message is displayed:
- "eth0: -- ERROR --
- Class: internal Software error
- Nr: 0xcc
- Msg: SkGeInitPort() cannot init running ports"
-Reason: You are using a driver compiled for single processor machines
- on a multiprocessor machine with SMP (Symmetric MultiProcessor)
- kernel.
-Solution: Configure your kernel appropriately and recompile the kernel or
- the modules.
-
-
-
-If your problem is not listed here, please contact SysKonnect's technical
-support for help (linux@syskonnect.de).
-When contacting our technical support, please ensure that the following
-information is available:
-- System Manufacturer and HW Informations (CPU, Memory... )
-- PCI-Boards in your system
-- Distribution
-- Kernel version
-- Driver version

+
+ The Spidernet Device Driver
+ ===========================
+
+Written by Linas Vepstas <linas@austin.ibm.com>
+
+Version of 7 June 2007
+
+Abstract
+========
+This document sketches the structure of portions of the spidernet
+device driver in the Linux kernel tree. The spidernet is a gigabit
+ethernet device built into the Toshiba southbridge commonly used
+in the SONY Playstation 3 and the IBM QS20 Cell blade.
+
+The Structure of the RX Ring.
+=============================
+The receive (RX) ring is a circular linked list of RX descriptors,
+together with three pointers into the ring that are used to manage its
+contents.
+
+The elements of the ring are called "descriptors" or "descrs"; they
+describe the received data. This includes a pointer to a buffer
+containing the received data, the buffer size, and various status bits.
+
+There are three primary states that a descriptor can be in: "empty",
+"full" and "not-in-use". An "empty" or "ready" descriptor is ready
+to receive data from the hardware. A "full" descriptor has data in it,
+and is waiting to be emptied and processed by the OS. A "not-in-use"
+descriptor is neither empty or full; it is simply not ready. It may
+not even have a data buffer in it, or is otherwise unusable.
+
+During normal operation, on device startup, the OS (specifically, the
+spidernet device driver) allocates a set of RX descriptors and RX
+buffers. These are all marked "empty", ready to receive data. This
+ring is handed off to the hardware, which sequentially fills in the
+buffers, and marks them "full". The OS follows up, taking the full
+buffers, processing them, and re-marking them empty.
+
+This filling and emptying is managed by three pointers, the "head"
+and "tail" pointers, managed by the OS, and a hardware current
+descriptor pointer (GDACTDPA). The GDACTDPA points at the descr
+currently being filled. When this descr is filled, the hardware
+marks it full, and advances the GDACTDPA by one. Thus, when there is
+flowing RX traffic, every descr behind it should be marked "full",
+and everything in front of it should be "empty". If the hardware
+discovers that the current descr is not empty, it will signal an
+interrupt, and halt processing.
+
+The tail pointer tails or trails the hardware pointer. When the
+hardware is ahead, the tail pointer will be pointing at a "full"
+descr. The OS will process this descr, and then mark it "not-in-use",
+and advance the tail pointer. Thus, when there is flowing RX traffic,
+all of the descrs in front of the tail pointer should be "full", and
+all of those behind it should be "not-in-use". When RX traffic is not
+flowing, then the tail pointer can catch up to the hardware pointer.
+The OS will then note that the current tail is "empty", and halt
+processing.
+
+The head pointer (somewhat mis-named) follows after the tail pointer.
+When traffic is flowing, then the head pointer will be pointing at
+a "not-in-use" descr. The OS will perform various housekeeping duties
+on this descr. This includes allocating a new data buffer and
+dma-mapping it so as to make it visible to the hardware. The OS will
+then mark the descr as "empty", ready to receive data. Thus, when there
+is flowing RX traffic, everything in front of the head pointer should
+be "not-in-use", and everything behind it should be "empty". If no
+RX traffic is flowing, then the head pointer can catch up to the tail
+pointer, at which point the OS will notice that the head descr is
+"empty", and it will halt processing.
+
+Thus, in an idle system, the GDACTDPA, tail and head pointers will
+all be pointing at the same descr, which should be "empty". All of the
+other descrs in the ring should be "empty" as well.
+
+The show_rx_chain() routine will print out the the locations of the
+GDACTDPA, tail and head pointers. It will also summarize the contents
+of the ring, starting at the tail pointer, and listing the status
+of the descrs that follow.
+
+A typical example of the output, for a nearly idle system, might be
+
+net eth1: Total number of descrs=256
+net eth1: Chain tail located at descr=20
+net eth1: Chain head is at 20
+net eth1: HW curr desc (GDACTDPA) is at 21
+net eth1: Have 1 descrs with stat=x40800101
+net eth1: HW next desc (GDACNEXTDA) is at 22
+net eth1: Last 255 descrs with stat=xa0800000
+
+In the above, the hardware has filled in one descr, number 20. Both
+head and tail are pointing at 20, because it has not yet been emptied.
+Meanwhile, hw is pointing at 21, which is free.
+
+The "Have nnn decrs" refers to the descr starting at the tail: in this
+case, nnn=1 descr, starting at descr 20. The "Last nnn descrs" refers
+to all of the rest of the descrs, from the last status change. The "nnn"
+is a count of how many descrs have exactly the same status.
+
+The status x4... corresponds to "full" and status xa... corresponds
+to "empty". The actual value printed is RXCOMST_A.
+
+In the device driver source code, a different set of names are
+used for these same concepts, so that
+
+"empty" == SPIDER_NET_DESCR_CARDOWNED == 0xa
+"full" == SPIDER_NET_DESCR_FRAME_END == 0x4
+"not in use" == SPIDER_NET_DESCR_NOT_IN_USE == 0xf
+
+
+The RX RAM full bug/feature
+===========================
+
+As long as the OS can empty out the RX buffers at a rate faster than
+the hardware can fill them, there is no problem. If, for some reason,
+the OS fails to empty the RX ring fast enough, the hardware GDACTDPA
+pointer will catch up to the head, notice the not-empty condition,
+ad stop. However, RX packets may still continue arriving on the wire.
+The spidernet chip can save some limited number of these in local RAM.
+When this local ram fills up, the spider chip will issue an interrupt
+indicating this (GHIINT0STS will show ERRINT, and the GRMFLLINT bit
+will be set in GHIINT1STS). When the RX ram full condition occurs,
+a certain bug/feature is triggered that has to be specially handled.
+This section describes the special handling for this condition.
+
+When the OS finally has a chance to run, it will empty out the RX ring.
+In particular, it will clear the descriptor on which the hardware had
+stopped. However, once the hardware has decided that a certain
+descriptor is invalid, it will not restart at that descriptor; instead
+it will restart at the next descr. This potentially will lead to a
+deadlock condition, as the tail pointer will be pointing at this descr,
+which, from the OS point of view, is empty; the OS will be waiting for
+this descr to be filled. However, the hardware has skipped this descr,
+and is filling the next descrs. Since the OS doesn't see this, there
+is a potential deadlock, with the OS waiting for one descr to fill,
+while the hardware is waiting for a different set of descrs to become
+empty.
+
+A call to show_rx_chain() at this point indicates the nature of the
+problem. A typical print when the network is hung shows the following:
+
+net eth1: Spider RX RAM full, incoming packets might be discarded!
+net eth1: Total number of descrs=256
+net eth1: Chain tail located at descr=255
+net eth1: Chain head is at 255
+net eth1: HW curr desc (GDACTDPA) is at 0
+net eth1: Have 1 descrs with stat=xa0800000
+net eth1: HW next desc (GDACNEXTDA) is at 1
+net eth1: Have 127 descrs with stat=x40800101
+net eth1: Have 1 descrs with stat=x40800001
+net eth1: Have 126 descrs with stat=x40800101
+net eth1: Last 1 descrs with stat=xa0800000
+
+Both the tail and head pointers are pointing at descr 255, which is
+marked xa... which is "empty". Thus, from the OS point of view, there
+is nothing to be done. In particular, there is the implicit assumption
+that everything in front of the "empty" descr must surely also be empty,
+as explained in the last section. The OS is waiting for descr 255 to
+become non-empty, which, in this case, will never happen.
+
+The HW pointer is at descr 0. This descr is marked 0x4.. or "full".
+Since its already full, the hardware can do nothing more, and thus has
+halted processing. Notice that descrs 0 through 254 are all marked
+"full", while descr 254 and 255 are empty. (The "Last 1 descrs" is
+descr 254, since tail was at 255.) Thus, the system is deadlocked,
+and there can be no forward progress; the OS thinks there's nothing
+to do, and the hardware has nowhere to put incoming data.
+
+This bug/feature is worked around with the spider_net_resync_head_ptr()
+routine. When the driver receives RX interrupts, but an examination
+of the RX chain seems to show it is empty, then it is probable that
+the hardware has skipped a descr or two (sometimes dozens under heavy
+network conditions). The spider_net_resync_head_ptr() subroutine will
+search the ring for the next full descr, and the driver will resume
+operations there. Since this will leave "holes" in the ring, there
+is also a spider_net_resync_tail_ptr() that will skip over such holes.
+
+As of this writing, the spider_net_resync() strategy seems to work very
+well, even under heavy network loads.
+
+
+The TX ring
+===========
+The TX ring uses a low-watermark interrupt scheme to make sure that
+the TX queue is appropriately serviced for large packet sizes.
+
+For packet sizes greater than about 1KBytes, the kernel can fill
+the TX ring quicker than the device can drain it. Once the ring
+is full, the netdev is stopped. When there is room in the ring,
+the netdev needs to be reawakened, so that more TX packets are placed
+in the ring. The hardware can empty the ring about four times per jiffy,
+so its not appropriate to wait for the poll routine to refill, since
+the poll routine runs only once per jiffy. The low-watermark mechanism
+marks a descr about 1/4th of the way from the bottom of the queue, so
+that an interrupt is generated when the descr is processed. This
+interrupt wakes up the netdev, which can then refill the queue.
+For large packets, this mechanism generates a relatively small number
+of interrupts, about 1K/sec. For smaller packets, this will drop to zero
+interrupts, as the hardware can empty the queue faster than the kernel
+can fill it.

+Linux power supply class
+========================
+
+Synopsis
+~~~~~~~~
+Power supply class used to represent battery, UPS, AC or DC power supply
+properties to user-space.
+
+It defines core set of attributes, which should be applicable to (almost)
+every power supply out there. Attributes are available via sysfs and uevent
+interfaces.
+
+Each attribute has well defined meaning, up to unit of measure used. While
+the attributes provided are believed to be universally applicable to any
+power supply, specific monitoring hardware may not be able to provide them
+all, so any of them may be skipped.
+
+Power supply class is extensible, and allows to define drivers own attributes.
+The core attribute set is subject to the standard Linux evolution (i.e.
+if it will be found that some attribute is applicable to many power supply
+types or their drivers, it can be added to the core set).
+
+It also integrates with LED framework, for the purpose of providing
+typically expected feedback of battery charging/fully charged status and
+AC/USB power supply online status. (Note that specific details of the
+indication (including whether to use it at all) are fully controllable by
+user and/or specific machine defaults, per design principles of LED
+framework).
+
+
+Attributes/properties
+~~~~~~~~~~~~~~~~~~~~~
+Power supply class has predefined set of attributes, this eliminates code
+duplication across drivers. Power supply class insist on reusing its
+predefined attributes *and* their units.
+
+So, userspace gets predictable set of attributes and their units for any
+kind of power supply, and can process/present them to a user in consistent
+manner. Results for different power supplies and machines are also directly
+comparable.
+
+See drivers/power/ds2760_battery.c and drivers/power/pda_power.c for the
+example how to declare and handle attributes.
+
+
+Units
+~~~~~
+Quoting include/linux/power_supply.h:
+
+ All voltages, currents, charges, energies, time and temperatures in µV,
+ µA, µAh, µWh, seconds and tenths of degree Celsius unless otherwise
+ stated. It's driver's job to convert its raw values to units in which
+ this class operates.
+
+
+Attributes/properties detailed
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+~ ~ ~ ~ ~ ~ ~ Charge/Energy/Capacity - how to not confuse ~ ~ ~ ~ ~ ~ ~
+~ ~
+~ Because both "charge" (µAh) and "energy" (µWh) represents "capacity" ~
+~ of battery, this class distinguish these terms. Don't mix them! ~
+~ ~
+~ CHARGE_* attributes represents capacity in µAh only. ~
+~ ENERGY_* attributes represents capacity in µWh only. ~

+
+Battery <-> external power supply interaction
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Often power supplies are acting as supplies and supplicants at the same
+time. Batteries are good example. So, batteries usually care if they're
+externally powered or not.
+
+For that case, power supply class implements notification mechanism for
+batteries.
+
+External power supply (AC) lists supplicants (batteries) names in
+"supplied_to" struct member, and each power_supply_changed() call
+issued by external power supply will notify supplicants via
+external_power_changed callback.
+
+
+QA
+~~
+Q: Where is POWER_SUPPLY_PROP_XYZ attribute?
+A: If you cannot find attribute suitable for your driver needs, feel free
+ to add it and send patch along with your driver.
+
+ The attributes available currently are the ones currently provided by the
+ drivers written.
+
+ Good candidates to add in future: model/part#, cycle_time, manufacturer,
+ etc.
+
+
+Q: I have some very specific attribute (e.g. battery color), should I add
+ this attribute to standard ones?
+A: Most likely, no. Such attribute can be placed in the driver itself, if
+ it is useful. Of course, if the attribute in question applicable to
+ large set of batteries, provided by many drivers, and/or comes from
+ some general battery specification/standard, it may be a candidate to
+ be added to the core attribute set.
+
+
+Q: Suppose, my battery monitoring chip/firmware does not provides capacity
+ in percents, but provides charge_{now,full,empty}. Should I calculate
+ percentage capacity manually, inside the driver, and register CAPACITY
+ attribute? The same question about time_to_empty/time_to_full.
+A: Most likely, no. This class is designed to export properties which are
+ directly measurable by the specific hardware available.
+
+ Inferring not available properties using some heuristics or mathematical
+ model is not subject of work for a battery driver. Such functionality
+ should be factored out, and in fact, apm_power, the driver to serve
+ legacy APM API on top of power supply class, uses a simple heuristic of
+ approximating remaining battery capacity based on its charge, current,
+ voltage and so on. But full-fledged battery model is likely not subject
+ for kernel at all, as it would require floating point calculation to deal
+ with things like differential equations and Kalman filters. This is
+ better be handled by batteryd/libbattery, yet to be written.

+
+This is the CFS scheduler.
+
+80% of CFS's design can be summed up in a single sentence: CFS basically
+models an "ideal, precise multi-tasking CPU" on real hardware.
+
+"Ideal multi-tasking CPU" is a (non-existent :-)) CPU that has 100%
+physical power and which can run each task at precise equal speed, in
+parallel, each at 1/nr_running speed. For example: if there are 2 tasks
+running then it runs each at 50% physical power - totally in parallel.
+
+On real hardware, we can run only a single task at once, so while that
+one task runs, the other tasks that are waiting for the CPU are at a
+disadvantage - the current task gets an unfair amount of CPU time. In
+CFS this fairness imbalance is expressed and tracked via the per-task
+p->wait_runtime (nanosec-unit) value. "wait_runtime" is the amount of
+time the task should now run on the CPU for it to become completely fair
+and balanced.
+
+( small detail: on 'ideal' hardware, the p->wait_runtime value would
+ always be zero - no task would ever get 'out of balance' from the
+ 'ideal' share of CPU time. )
+
+CFS's task picking logic is based on this p->wait_runtime value and it
+is thus very simple: it always tries to run the task with the largest
+p->wait_runtime value. In other words, CFS tries to run the task with
+the 'gravest need' for more CPU time. So CFS always tries to split up
+CPU time between runnable tasks as close to 'ideal multitasking
+hardware' as possible.
+
+Most of the rest of CFS's design just falls out of this really simple
+concept, with a few add-on embellishments like nice levels,
+multiprocessing and various algorithm variants to recognize sleepers.
+
+In practice it works like this: the system runs a task a bit, and when
+the task schedules (or a scheduler tick happens) the task's CPU usage is
+'accounted for': the (small) time it just spent using the physical CPU
+is deducted from p->wait_runtime. [minus the 'fair share' it would have
+gotten anyway]. Once p->wait_runtime gets low enough so that another
+task becomes the 'leftmost task' of the time-ordered rbtree it maintains
+(plus a small amount of 'granularity' distance relative to the leftmost
+task so that we do not over-schedule tasks and trash the cache) then the
+new leftmost task is picked and the current task is preempted.
+
+The rq->fair_clock value tracks the 'CPU time a runnable task would have
+fairly gotten, had it been runnable during that time'. So by using
+rq->fair_clock values we can accurately timestamp and measure the
+'expected CPU time' a task should have gotten. All runnable tasks are
+sorted in the rbtree by the "rq->fair_clock - p->wait_runtime" key, and
+CFS picks the 'leftmost' task and sticks to it. As the system progresses
+forwards, newly woken tasks are put into the tree more and more to the
+right - slowly but surely giving a chance for every task to become the
+'leftmost task' and thus get on the CPU within a deterministic amount of
+time.
+
+Some implementation details:
+
+ - the introduction of Scheduling Classes: an extensible hierarchy of
+ scheduler modules. These modules encapsulate scheduling policy
+ details and are handled by the scheduler core without the core
+ code assuming about them too much.
+
+ - sched_fair.c implements the 'CFS desktop scheduler': it is a
+ replacement for the vanilla scheduler's SCHED_OTHER interactivity
+ code.
+
+ I'd like to give credit to Con Kolivas for the general approach here:
+ he has proven via RSDL/SD that 'fair scheduling' is possible and that
+ it results in better desktop scheduling. Kudos Con!
+
+ The CFS patch uses a completely different approach and implementation
+ from RSDL/SD. My goal was to make CFS's interactivity quality exceed
+ that of RSDL/SD, which is a high standard to meet :-) Testing
+ feedback is welcome to decide this one way or another. [ and, in any
+ case, all of SD's logic could be added via a kernel/sched_sd.c module
+ as well, if Con is interested in such an approach. ]
+
+ CFS's design is quite radical: it does not use runqueues, it uses a
+ time-ordered rbtree to build a 'timeline' of future task execution,
+ and thus has no 'array switch' artifacts (by which both the vanilla
+ scheduler and RSDL/SD are affected).
+
+ CFS uses nanosecond granularity accounting and does not rely on any
+ jiffies or other HZ detail. Thus the CFS scheduler has no notion of
+ 'timeslices' and has no heuristics whatsoever. There is only one
+ central tunable:
+
+ /proc/sys/kernel/sched_granularity_ns
+
+ which can be used to tune the scheduler from 'desktop' (low
+ latencies) to 'server' (good batching) workloads. It defaults to a
+ setting suitable for desktop workloads. SCHED_BATCH is handled by the
+ CFS scheduler module too.
+
+ Due to its design, the CFS scheduler is not prone to any of the
+ 'attacks' that exist today against the heuristics of the stock
+ scheduler: fiftyp.c, thud.c, chew.c, ring-test.c, massive_intr.c all
+ work fine and do not impact interactivity and produce the expected
+ behavior.
+
+ the CFS scheduler has a much stronger handling of nice levels and
+ SCHED_BATCH: both types of workloads should be isolated much more
+ agressively than under the vanilla scheduler.
+
+ ( another detail: due to nanosec accounting and timeline sorting,
+ sched_yield() support is very simple under CFS, and in fact under
+ CFS sched_yield() behaves much better than under any other
+ scheduler i have tested so far. )
+
+ - sched_rt.c implements SCHED_FIFO and SCHED_RR semantics, in a simpler
+ way than the vanilla scheduler does. It uses 100 runqueues (for all
+ 100 RT priority levels, instead of 140 in the vanilla scheduler)
+ and it needs no expired array.
+
+ - reworked/sanitized SMP load-balancing: the runqueue-walking
+ assumptions are gone from the load-balancing code now, and
+ iterators of the scheduling modules are used. The balancing code got
+ quite a bit simpler as a result.

+Rules on how to access information in the Linux kernel sysfs
+
+The kernel exported sysfs exports internal kernel implementation-details
+and depends on internal kernel structures and layout. It is agreed upon
+by the kernel developers that the Linux kernel does not provide a stable
+internal API. As sysfs is a direct export of kernel internal
+structures, the sysfs interface can not provide a stable interface eighter,
+it may always change along with internal kernel changes.
+
+To minimize the risk of breaking users of sysfs, which are in most cases
+low-level userspace applications, with a new kernel release, the users
+of sysfs must follow some rules to use an as abstract-as-possible way to
+access this filesystem. The current udev and HAL programs already
+implement this and users are encouraged to plug, if possible, into the
+abstractions these programs provide instead of accessing sysfs
+directly.
+
+But if you really do want or need to access sysfs directly, please follow
+the following rules and then your programs should work with future
+versions of the sysfs interface.
+
+- Do not use libsysfs
+ It makes assumptions about sysfs which are not true. Its API does not
+ offer any abstraction, it exposes all the kernel driver-core
+ implementation details in its own API. Therefore it is not better than
+ reading directories and opening the files yourself.
+ Also, it is not actively maintained, in the sense of reflecting the
+ current kernel-development. The goal of providing a stable interface
+ to sysfs has failed, it causes more problems, than it solves. It
+ violates many of the rules in this document.
+
+- sysfs is always at /sys
+ Parsing /proc/mounts is a waste of time. Other mount points are a
+ system configuration bug you should not try to solve. For test cases,
+ possibly support a SYSFS_PATH environment variable to overwrite the
+ applications behavior, but never try to search for sysfs. Never try
+ to mount it, if you are not an early boot script.
+
+- devices are only "devices"
+ There is no such thing like class-, bus-, physical devices,
+ interfaces, and such that you can rely on in userspace. Everything is
+ just simply a "device". Class-, bus-, physical, ... types are just
+ kernel implementation details, which should not be expected by
+ applications that look for devices in sysfs.
+
+ The properties of a device are:
+ o devpath (/devices/pci0000:00/0000:00:1d.1/usb2/2-2/2-2:1.0)
+ - identical to the DEVPATH value in the event sent from the kernel
+ at device creation and removal
+ - the unique key to the device at that point in time
+ - the kernels path to the device-directory without the leading
+ /sys, and always starting with with a slash
+ - all elements of a devpath must be real directories. Symlinks
+ pointing to /sys/devices must always be resolved to their real
+ target, and the target path must be used to access the device.
+ That way the devpath to the device matches the devpath of the
+ kernel used at event time.
+ - using or exposing symlink values as elements in a devpath string
+ is a bug in the application
+
+ o kernel name (sda, tty, 0000:00:1f.2, ...)
+ - a directory name, identical to the last element of the devpath
+ - applications need to handle spaces and characters like '!' in
+ the name
+
+ o subsystem (block, tty, pci, ...)
+ - simple string, never a path or a link
+ - retrieved by reading the "subsystem"-link and using only the
+ last element of the target path
+
+ o driver (tg3, ata_piix, uhci_hcd)
+ - a simple string, which may contain spaces, never a path or a
+ link
+ - it is retrieved by reading the "driver"-link and using only the
+ last element of the target path
+ - devices which do not have "driver"-link, just do not have a
+ driver; copying the driver value in a child device context, is a
+ bug in the application
+
+ o attributes
+ - the files in the device directory or files below a subdirectories
+ of the same device directory
+ - accessing attributes reached by a symlink pointing to another device,
+ like the "device"-link, is a bug in the application
+
+ Everything else is just a kernel driver-core implementation detail,
+ that should not be assumed to be stable across kernel releases.
+
+- Properties of parent devices never belong into a child device.
+ Always look at the parent devices themselves for determining device
+ context properties. If the device 'eth0' or 'sda' does not have a
+ "driver"-link, then this device does not have a driver. Its value is empty.
+ Never copy any property of the parent-device into a child-device. Parent
+ device-properties may change dynamically without any notice to the
+ child device.
+
+- Hierarchy in a single device-tree
+ There is only one valid place in sysfs where hierarchy can be examined
+ and this is below: /sys/devices.
+ It is planned, that all device directories will end up in the tree
+ below this directory.
+
+- Classification by subsystem
+ There are currently three places for classification of devices:
+ /sys/block, /sys/class and /sys/bus. It is planned that these will
+ not contain any device-directories themselves, but only flat lists of
+ symlinks pointing to the unified /sys/devices tree.
+ All three places have completely different rules on how to access
+ device information. It is planned to merge all three
+ classification-directories into one place at /sys/subsystem,
+ following the layout of the bus-directories. All buses and
+ classes, including the converted block-subsystem, will show up
+ there.
+ The devices belonging to a subsystem will create a symlink in the
+ "devices" directory at /sys/subsystem/<name>/devices.
+
+ If /sys/subsystem exists, /sys/bus, /sys/class and /sys/block can be
+ ignored. If it does not exist, you have always to scan all three
+ places, as the kernel is free to move a subsystem from one place to
+ the other, as long as the devices are still reachable by the same
+ subsystem name.
+
+ Assuming /sys/class/<subsystem> and /sys/bus/<subsystem>, or
+ /sys/block and /sys/class/block are not interchangeable, is a bug in
+ the application.
+
+- Block
+ The converted block-subsystem at /sys/class/block, or
+ /sys/subsystem/block will contain the links for disks and partitions
+ at the same level, never in a hierarchy. Assuming the block-subsytem to
+ contain only disks and not partition-devices in the same flat list is
+ a bug in the application.
+
+- "device"-link and <subsystem>:<kernel name>-links
+ Never depend on the "device"-link. The "device"-link is a workaround
+ for the old layout, where class-devices are not created in
+ /sys/devices/ like the bus-devices. If the link-resolving of a
+ device-directory does not end in /sys/devices/, you can use the
+ "device"-link to find the parent devices in /sys/devices/. That is the
+ single valid use of the "device"-link, it must never appear in any
+ path as an element. Assuming the existence of the "device"-link for
+ a device in /sys/devices/ is a bug in the application.
+ Accessing /sys/class/net/eth0/device is a bug in the application.
+
+ Never depend on the class-specific links back to the /sys/class
+ directory. These links are also a workaround for the design mistake
+ that class-devices are not created in /sys/devices. If a device
+ directory does not contain directories for child devices, these links
+ may be used to find the child devices in /sys/class. That is the single
+ valid use of these links, they must never appear in any path as an
+ element. Assuming the existence of these links for devices which are
+ real child device directories in the /sys/devices tree, is a bug in
+ the application.
+
+ It is planned to remove all these links when when all class-device
+ directories live in /sys/devices.
+
+- Position of devices along device chain can change.
+ Never depend on a specific parent device position in the devpath,
+ or the chain of parent devices. The kernel is free to insert devices into
+ the chain. You must always request the parent device you are looking for
+ by its subsystem value. You need to walk up the chain until you find
+ the device that matches the expected subsystem. Depending on a specific
+ position of a parent device, or exposing relative paths, using "../" to
+ access the chain of parents, is a bug in the application.

+ USB device persistence during system suspend
+
+ Alan Stern <stern@rowland.harvard.edu>
+
+ September 2, 2006 (Updated May 29, 2007)
+
+
+ What is the problem?
+
+According to the USB specification, when a USB bus is suspended the
+bus must continue to supply suspend current (around 1-5 mA). This
+is so that devices can maintain their internal state and hubs can
+detect connect-change events (devices being plugged in or unplugged).
+The technical term is "power session".
+
+If a USB device's power session is interrupted then the system is
+required to behave as though the device has been unplugged. It's a
+conservative approach; in the absence of suspend current the computer
+has no way to know what has actually happened. Perhaps the same
+device is still attached or perhaps it was removed and a different
+device plugged into the port. The system must assume the worst.
+
+By default, Linux behaves according to the spec. If a USB host
+controller loses power during a system suspend, then when the system
+wakes up all the devices attached to that controller are treated as
+though they had disconnected. This is always safe and it is the
+"officially correct" thing to do.
+
+For many sorts of devices this behavior doesn't matter in the least.
+If the kernel wants to believe that your USB keyboard was unplugged
+while the system was asleep and a new keyboard was plugged in when the
+system woke up, who cares? It'll still work the same when you type on
+it.
+
+Unfortunately problems _can_ arise, particularly with mass-storage
+devices. The effect is exactly the same as if the device really had
+been unplugged while the system was suspended. If you had a mounted
+filesystem on the device, you're out of luck -- everything in that
+filesystem is now inaccessible. This is especially annoying if your
+root filesystem was located on the device, since your system will
+instantly crash.
+
+Loss of power isn't the only mechanism to worry about. Anything that
+interrupts a power session will have the same effect. For example,
+even though suspend current may have been maintained while the system
+was asleep, on many systems during the initial stages of wakeup the
+firmware (i.e., the BIOS) resets the motherboard's USB host
+controllers. Result: all the power sessions are destroyed and again
+it's as though you had unplugged all the USB devices. Yes, it's
+entirely the BIOS's fault, but that doesn't do _you_ any good unless
+you can convince the BIOS supplier to fix the problem (lots of luck!).
+
+On many systems the USB host controllers will get reset after a
+suspend-to-RAM. On almost all systems, no suspend current is
+available during hibernation (also known as swsusp or suspend-to-disk).
+You can check the kernel log after resuming to see if either of these
+has happened; look for lines saying "root hub lost power or was reset".
+
+In practice, people are forced to unmount any filesystems on a USB
+device before suspending. If the root filesystem is on a USB device,
+the system can't be suspended at all. (All right, it _can_ be
+suspended -- but it will crash as soon as it wakes up, which isn't
+much better.)
+
+
+ What is the solution?
+
+Setting CONFIG_USB_PERSIST will cause the kernel to work around these
+issues. It enables a mode in which the core USB device data
+structures are allowed to persist across a power-session disruption.
+It works like this. If the kernel sees that a USB host controller is
+not in the expected state during resume (i.e., if the controller was
+reset or otherwise had lost power) then it applies a persistence check
+to each of the USB devices below that controller for which the
+"persist" attribute is set. It doesn't try to resume the device; that
+can't work once the power session is gone. Instead it issues a USB
+port reset and then re-enumerates the device. (This is exactly the
+same thing that happens whenever a USB device is reset.) If the
+re-enumeration shows that the device now attached to that port has the
+same descriptors as before, including the Vendor and Product IDs, then
+the kernel continues to use the same device structure. In effect, the
+kernel treats the device as though it had merely been reset instead of
+unplugged.
+
+If no device is now attached to the port, or if the descriptors are
+different from what the kernel remembers, then the treatment is what
+you would expect. The kernel destroys the old device structure and
+behaves as though the old device had been unplugged and a new device
+plugged in, just as it would without the CONFIG_USB_PERSIST option.
+
+The end result is that the USB device remains available and usable.
+Filesystem mounts and memory mappings are unaffected, and the world is
+now a good and happy place.
+
+Note that even when CONFIG_USB_PERSIST is set, the "persist" feature
+will be applied only to those devices for which it is enabled. You
+can enable the feature by doing (as root):
+
+ echo 1 >/sys/bus/usb/devices/.../power/persist
+
+where the "..." should be filled in the with the device's ID. Disable
+the feature by writing 0 instead of 1. For hubs the feature is
+automatically and permanently enabled, so you only have to worry about
+setting it for devices where it really matters.
+
+
+ Is this the best solution?
+
+Perhaps not. Arguably, keeping track of mounted filesystems and
+memory mappings across device disconnects should be handled by a
+centralized Logical Volume Manager. Such a solution would allow you
+to plug in a USB flash device, create a persistent volume associated
+with it, unplug the flash device, plug it back in later, and still
+have the same persistent volume associated with the device. As such
+it would be more far-reaching than CONFIG_USB_PERSIST.
+
+On the other hand, writing a persistent volume manager would be a big
+job and using it would require significant input from the user. This
+solution is much quicker and easier -- and it exists now, a giant
+point in its favor!
+
+Furthermore, the USB_PERSIST option applies to _all_ USB devices, not
+just mass-storage devices. It might turn out to be equally useful for
+other device types, such as network interfaces.
+
+
+ WARNING: Using CONFIG_USB_PERSIST can be dangerous!!
+
+When recovering an interrupted power session the kernel does its best
+to make sure the USB device hasn't been changed; that is, the same
+device is still plugged into the port as before. But the checks
+aren't guaranteed to be 100% accurate.
+
+If you replace one USB device with another of the same type (same
+manufacturer, same IDs, and so on) there's an excellent chance the
+kernel won't detect the change. Serial numbers and other strings are
+not compared. In many cases it wouldn't help if they were, because
+manufacturers frequently omit serial numbers entirely in their
+devices.
+
+Furthermore it's quite possible to leave a USB device exactly the same
+while changing its media. If you replace the flash memory card in a
+USB card reader while the system is asleep, the kernel will have no
+way to know you did it. The kernel will assume that nothing has
+happened and will continue to use the partition tables, inodes, and
+memory mappings for the old card.
+
+If the kernel gets fooled in this way, it's almost certain to cause
+data corruption and to crash your system. You'll have no one to blame
+but yourself.
+
+YOU HAVE BEEN WARNED! USE AT YOUR OWN RISK!
+
+That having been said, most of the time there shouldn't be any trouble
+at all. The "persist" feature can be extremely useful. Make the most
+of it.

+Why the "volatile" type class should not be used
+------------------------------------------------
+
+C programmers have often taken volatile to mean that the variable could be
+changed outside of the current thread of execution; as a result, they are
+sometimes tempted to use it in kernel code when shared data structures are
+being used. In other words, they have been known to treat volatile types
+as a sort of easy atomic variable, which they are not. The use of volatile in
+kernel code is almost never correct; this document describes why.
+
+The key point to understand with regard to volatile is that its purpose is
+to suppress optimization, which is almost never what one really wants to
+do. In the kernel, one must protect shared data structures against
+unwanted concurrent access, which is very much a different task. The
+process of protecting against unwanted concurrency will also avoid almost
+all optimization-related problems in a more efficient way.
+
+Like volatile, the kernel primitives which make concurrent access to data
+safe (spinlocks, mutexes, memory barriers, etc.) are designed to prevent
+unwanted optimization. If they are being used properly, there will be no
+need to use volatile as well. If volatile is still necessary, there is
+almost certainly a bug in the code somewhere. In properly-written kernel
+code, volatile can only serve to slow things down.
+
+Consider a typical block of kernel code:
+
+ spin_lock(&the_lock);
+ do_something_on(&shared_data);
+ do_something_else_with(&shared_data);
+ spin_unlock(&the_lock);
+
+If all the code follows the locking rules, the value of shared_data cannot
+change unexpectedly while the_lock is held. Any other code which might
+want to play with that data will be waiting on the lock. The spinlock
+primitives act as memory barriers - they are explicitly written to do so -
+meaning that data accesses will not be optimized across them. So the
+compiler might think it knows what will be in shared_data, but the
+spin_lock() call, since it acts as a memory barrier, will force it to
+forget anything it knows. There will be no optimization problems with
+accesses to that data.
+
+If shared_data were declared volatile, the locking would still be
+necessary. But the compiler would also be prevented from optimizing access
+to shared_data _within_ the critical section, when we know that nobody else
+can be working with it. While the lock is held, shared_data is not
+volatile. When dealing with shared data, proper locking makes volatile
+unnecessary - and potentially harmful.
+
+The volatile storage class was originally meant for memory-mapped I/O
+registers. Within the kernel, register accesses, too, should be protected
+by locks, but one also does not want the compiler "optimizing" register
+accesses within a critical section. But, within the kernel, I/O memory
+accesses are always done through accessor functions; accessing I/O memory
+directly through pointers is frowned upon and does not work on all
+architectures. Those accessors are written to prevent unwanted
+optimization, so, once again, volatile is unnecessary.
+
+Another situation where one might be tempted to use volatile is
+when the processor is busy-waiting on the value of a variable. The right
+way to perform a busy wait is:
+
+ while (my_variable != what_i_want)
+ cpu_relax();
+
+The cpu_relax() call can lower CPU power consumption or yield to a
+hyperthreaded twin processor; it also happens to serve as a memory barrier,
+so, once again, volatile is unnecessary. Of course, busy-waiting is
+generally an anti-social act to begin with.
+
+There are still a few rare situations where volatile makes sense in the
+kernel:
+
+ - The above-mentioned accessor functions might use volatile on
+ architectures where direct I/O memory access does work. Essentially,
+ each accessor call becomes a little critical section on its own and
+ ensures that the access happens as expected by the programmer.
+
+ - Inline assembly code which changes memory, but which has no other
+ visible side effects, risks being deleted by GCC. Adding the volatile
+ keyword to asm statements will prevent this removal.
+
+ - The jiffies variable is special in that it can have a different value
+ every time it is referenced, but it can be read without any special
+ locking. So jiffies can be volatile, but the addition of other
+ variables of this type is strongly frowned upon. Jiffies is considered
+ to be a "stupid legacy" issue (Linus's words) in this regard; fixing it
+ would be more trouble than it is worth.
+
+ - Pointers to data structures in coherent memory which might be modified
+ by I/O devices can, sometimes, legitimately be volatile. A ring buffer
+ used by a network adapter, where that adapter changes pointers to
+ indicate which descriptors have been processed, is an example of this
+ type of situation.
+
+For most code, none of the above justifications for volatile apply. As a
+result, the use of volatile is likely to be seen as a bug and will bring
+additional scrutiny to the code. Developers who are tempted to use
+volatile should take a step back and think about what they are truly trying
+to accomplish.
+
+Patches to remove volatile variables are generally welcome - as long as
+they come with a justification which shows that the concurrency issues have
+been properly thought through.

[FIXME -- better explanations]
-Implementations in the current drivers in the kernel tree:
-
-Here I have tried to summarize what the different drivers support and
-where they do strange things compared to the other drivers.
-
-acquirewdt.c -- Acquire Single Board Computer
-
- This driver has a hardcoded timeout of 1 minute
-
- Supports CONFIG_WATCHDOG_NOWAYOUT
-
- GETSUPPORT returns KEEPALIVEPING. GETSTATUS will return 1 if
- the device is open, 0 if not. [FIXME -- isn't this rather
- silly? To be able to use the ioctl, the device must be open
- and so GETSTATUS will always return 1].
-
-advantechwdt.c -- Advantech Single Board Computer
-
- Timeout that defaults to 60 seconds, supports SETTIMEOUT.
-
- Supports CONFIG_WATCHDOG_NOWAYOUT
-
- GETSUPPORT returns WDIOF_KEEPALIVEPING and WDIOF_SETTIMEOUT.
- The GETSTATUS call returns if the device is open or not.
- [FIXME -- silliness again?]
-
-booke_wdt.c -- PowerPC BookE Watchdog Timer
-
- Timeout default varies according to frequency, supports
- SETTIMEOUT
-
- Watchdog cannot be turned off, CONFIG_WATCHDOG_NOWAYOUT
- does not make sense
-
- GETSUPPORT returns the watchdog_info struct, and
- GETSTATUS returns the supported options. GETBOOTSTATUS
- returns a 1 if the last reset was caused by the
- watchdog and a 0 otherwise. This watchdog cannot be
- disabled once it has been started. The wdt_period kernel
- parameter selects which bit of the time base changing
- from 0->1 will trigger the watchdog exception. Changing
- the timeout from the ioctl calls will change the
- wdt_period as defined above. Finally if you would like to
- replace the default Watchdog Handler you can implement the
- WatchdogHandler() function in your own code.
-
-eurotechwdt.c -- Eurotech CPU-1220/1410
-
- The timeout can be set using the SETTIMEOUT ioctl and defaults
- to 60 seconds.
-
- Also has a module parameter "ev", event type which controls
- what should happen on a timeout, the string "int" or anything
- else that causes a reboot. [FIXME -- better description]
-
- Supports CONFIG_WATCHDOG_NOWAYOUT
-
- GETSUPPORT returns CARDRESET and WDIOF_SETTIMEOUT but
- GETSTATUS is not supported and GETBOOTSTATUS just returns 0.
-
-i810-tco.c -- Intel 810 chipset
-
- Also has support for a lot of other i8x0 stuff, but the
- watchdog is one of the things.
-
- The timeout is set using the module parameter "i810_margin",
- which is in steps of 0.6 seconds where 2<i810_margin<64. The
- driver supports the SETTIMEOUT ioctl.
-
- Supports CONFIG_WATCHDOG_NOWAYOUT.
-
- GETSUPPORT returns WDIOF_SETTIMEOUT. The GETSTATUS call
- returns some kind of timer value which ist not compatible with
- the other drivers. GETBOOT status returns some kind of
- hardware specific boot status. [FIXME -- describe this]
-
-ib700wdt.c -- IB700 Single Board Computer
-
- Default timeout of 30 seconds and the timeout is settable
- using the SETTIMEOUT ioctl. Note that only a few timeout
- values are supported.
-
- Supports CONFIG_WATCHDOG_NOWAYOUT
-
- GETSUPPORT returns WDIOF_KEEPALIVEPING and WDIOF_SETTIMEOUT.
- The GETSTATUS call returns if the device is open or not.
- [FIXME -- silliness again?]
-
-machzwd.c -- MachZ ZF-Logic
-
- Hardcoded timeout of 10 seconds
-
- Has a module parameter "action" that controls what happens
- when the timeout runs out which can be 0 = RESET (default),
- 1 = SMI, 2 = NMI, 3 = SCI.
-
- Supports CONFIG_WATCHDOG_NOWAYOUT and the magic character
- 'V' close handling.
-
- GETSUPPORT returns WDIOF_KEEPALIVEPING, and the GETSTATUS call
- returns if the device is open or not. [FIXME -- silliness
- again?]
-
-mixcomwd.c -- MixCom Watchdog
-
- [FIXME -- I'm unable to tell what the timeout is]
-
- Supports CONFIG_WATCHDOG_NOWAYOUT
-
- GETSUPPORT returns WDIOF_KEEPALIVEPING, GETSTATUS returns if
- the device is opened or not [FIXME -- I'm not really sure how
- this works, there seems to be some magic connected to
- CONFIG_WATCHDOG_NOWAYOUT]
-
-pcwd.c -- Berkshire PC Watchdog
-
- Hardcoded timeout of 1.5 seconds
-
- Supports CONFIG_WATCHDOG_NOWAYOUT
-
- GETSUPPORT returns WDIOF_OVERHEAT|WDIOF_CARDRESET and both
- GETSTATUS and GETBOOTSTATUS return something useful.
-
- The SETOPTIONS call can be used to enable and disable the card
- and to ask the driver to call panic if the system overheats.
-
-sbc60xxwdt.c -- 60xx Single Board Computer

- Watchdog Timer Interfaces For The Linux Operating System
-
- Alan Cox <alan@lxorguk.ukuu.org.uk>
-
- Custom Linux Driver And Program Development
-
-
-The following watchdog drivers are currently implemented:
-
- ICS WDT501-P
- ICS WDT501-P (no fan tachometer)
- ICS WDT500-P
- Software Only
- SA1100 Internal Watchdog
- Berkshire Products PC Watchdog Revision A & C (by Ken Hollis)
-
-
-All six interfaces provide /dev/watchdog, which when open must be written
-to within a timeout or the machine will reboot. Each write delays the reboot
-time another timeout. In the case of the software watchdog the ability to
-reboot will depend on the state of the machines and interrupts. The hardware
-boards physically pull the machine down off their own onboard timers and
-will reboot from almost anything.
-
-A second temperature monitoring interface is available on the WDT501P cards
-and some Berkshire cards. This provides /dev/temperature. This is the machine
-internal temperature in degrees Fahrenheit. Each read returns a single byte
-giving the temperature.
-
-The third interface logs kernel messages on additional alert events.
-
-Both software and hardware watchdog drivers are available in the standard
-kernel. If you are using the software watchdog, you probably also want
-to use "panic=60" as a boot argument as well.
-
-The wdt card cannot be safely probed for. Instead you need to pass
-wdt=ioaddr,irq as a boot parameter - eg "wdt=0x240,11".
-
-The SA1100 watchdog module can be configured with the "sa1100_margin"
-commandline argument which specifies timeout value in seconds.
-
-The i810 TCO watchdog modules can be configured with the "i810_margin"
-commandline argument which specifies the counter initial value. The counter
-is decremented every 0.6 seconds and default to 50 (30 seconds). Values can
-range between 3 and 63.
-
-The i810 TCO watchdog driver also implements the WDIOC_GETSTATUS and
-WDIOC_GETBOOTSTATUS ioctl()s. WDIOC_GETSTATUS returns the actual counter value
-and WDIOC_GETBOOTSTATUS returns the value of TCO2 Status Register (see Intel's
-documentation for the 82801AA and 82801AB datasheet).

-# A buffer of size EDDMAXNR*(EDDEXTSIZE+EDDPARMSIZE) is reserved for our use
-# in the boot_params at EDDBUF. The first four bytes of which are
-# used to store the device number, interface support map and version
-# results from fn41. The next four bytes are used to store the legacy
-# cylinders, heads, and sectors from fn08. The following 74 bytes are used to
-# store the results from fn48. Starting from device 80h, fn41, then fn48
-# are called and their results stored in EDDBUF+n*(EDDEXTSIZE+EDDPARMIZE).
-# Then the pointer is incremented to store the data for the next call.
-# This repeats until either a device doesn't exist, or until EDDMAXNR
-# devices have been stored.
-# The one tricky part is that ds:si always points EDDEXTSIZE bytes into
-# the structure, and the fn41 and fn08 results are stored at offsets
-# from there. This removes the need to increment the pointer for
-# every store, and leaves it ready for the fn48 call.
-# A second one-byte buffer, EDDNR, in the boot_params stores
-# the number of BIOS devices which exist, up to EDDMAXNR.

- * setup.S Copyright (C) 1991, 1992 Linus Torvalds
- *
- * setup.s is responsible for getting the system data from the BIOS,
- * and putting them into the appropriate places in system memory.
- * both setup.s and system has been loaded by the bootblock.
- *
- * This code asks the bios for memory/disk/other parameters, and
- * puts them in a "safe" place: 0x90000-0x901FF, ie where the
- * boot-block used to be. It is then up to the protected mode
- * system to read them from there before the area is overwritten
- * for buffer-blocks.
- *
- * Move PS/2 aux init code to psaux.c
- * (troyer@saifr00.cfsat.Honeywell.COM) 03Oct92
- *
- * some changes and additional features by Christoph Niemann,
- * March 1993/June 1994 (Christoph.Niemann@linux.org)
- *
- * add APM BIOS checking by Stephen Rothwell, May 1994
- * (sfr@canb.auug.org.au)
- *
- * High load stuff, initrd support and position independency
- * by Hans Lermen & Werner Almesberger, February 1996
- * <lermen@elserv.ffm.fgan.de>, <almesber@lrc.epfl.ch>
- *
- * Video handling moved to video.S by Martin Mares, March 1996
- * <mj@k332.feld.cvut.cz>
- *
- * Extended memory detection scheme retwiddled by orc@pell.chi.il.us (david
- * parsons) to avoid loadlin confusion, July 1997
- *
- * Transcribed from Intel (as86) -> AT&T (gas) by Chris Noe, May 1999.
- * <stiker@northlink.com>
- *
- * Fix to work around buggy BIOSes which don't use carry bit correctly
- * and/or report extended memory in CX/DX for e801h memory size detection
- * call. As a result the kernel got wrong figures. The int15/e801h docs
- * from Ralf Brown interrupt list seem to indicate AX/BX should be used
- * anyway. So to avoid breaking many machines (presumably there was a reason
- * to orginally use CX/DX instead of AX/BX), we do a kludge to see
- * if CX/DX have been changed in the e801 call and if so use AX/BX .
- * Michael Miller, April 2001 <michaelm@mjmm.org>

- * setup.S Copyright (C) 1991, 1992 Linus Torvalds
- *
- * setup.s is responsible for getting the system data from the BIOS,
- * and putting them into the appropriate places in system memory.
- * both setup.s and system has been loaded by the bootblock.
- *
- * This code asks the bios for memory/disk/other parameters, and
- * puts them in a "safe" place: 0x90000-0x901FF, ie where the
- * boot-block used to be. It is then up to the protected mode
- * system to read them from there before the area is overwritten
- * for buffer-blocks.

- * <stiker@northlink.com>
- *
- * Fix to work around buggy BIOSes which don't use carry bit correctly
- * and/or report extended memory in CX/DX for e801h memory size detection
- * call. As a result the kernel got wrong figures. The int15/e801h docs
- * from Ralf Brown interrupt list seem to indicate AX/BX should be used
- * anyway. So to avoid breaking many machines (presumably there was a reason
- * to orginally use CX/DX instead of AX/BX), we do a kludge to see
- * if CX/DX have been changed in the e801 call and if so use AX/BX .

+/*
+ Theory of operation
+ -------------------
+
+ The SX4 (PDC20621) chip features a single Host DMA (HDMA) copy
+ engine, DIMM memory, and four ATA engines (one per SATA port).
+ Data is copied to/from DIMM memory by the HDMA engine, before
+ handing off to one (or more) of the ATA engines. The ATA
+ engines operate solely on DIMM memory.
+
+ The SX4 behaves like a PATA chip, with no SATA controls or
+ knowledge whatsoever, leading to the presumption that
+ PATA<->SATA bridges exist on SX4 boards, external to the
+ PDC20621 chip itself.
+
+ The chip is quite capable, supporting an XOR engine and linked
+ hardware commands (permits a string to transactions to be
+ submitted and waited-on as a single unit), and an optional
+ microprocessor.
+
+ The limiting factor is largely software. This Linux driver was
+ written to multiplex the single HDMA engine to copy disk
+ transactions into a fixed DIMM memory space, from where an ATA
+ engine takes over. As a result, each WRITE looks like this:
+
+ submit HDMA packet to hardware
+ hardware copies data from system memory to DIMM
+ hardware raises interrupt
+
+ submit ATA packet to hardware
+ hardware executes ATA WRITE command, w/ data in DIMM
+ hardware raises interrupt
+
+ and each READ looks like this:
+
+ submit ATA packet to hardware
+ hardware executes ATA READ command, w/ data in DIMM
+ hardware raises interrupt
+
+ submit HDMA packet to hardware
+ hardware copies data from DIMM to system memory
+ hardware raises interrupt
+
+ This is a very slow, lock-step way of doing things that can
+ certainly be improved by motivated kernel hackers.

- * General notes:
- *
- * - All ACSI devices (disks, CD-ROMs, ...) use major number 28.
- * Minors are organized like it is with SCSI: The upper 4 bits
- * identify the device, the lower 4 bits the partition.
- * The device numbers (the upper 4 bits) are given in the same
- * order as the devices are found on the bus.
- * - Up to 8 LUNs are supported for each target (if CONFIG_ACSI_MULTI_LUN
- * is defined), but only a total of 16 devices (due to minor
- * numbers...). Note that Atari allows only a maximum of 4 targets
- * (i.e. controllers, not devices) on the ACSI bus!
- * - A optimizing scheme similar to SCSI scatter-gather is implemented.
- * - Removable media are supported. After a medium change to device
- * is reinitialized (partition check etc.). Also, if the device
- * knows the PREVENT/ALLOW MEDIUM REMOVAL command, the door should
- * be locked and unlocked when mounting the first or unmounting the
- * last filesystem on the device. The code is untested, because I

- <http://www.tldp.org/docs.html#howto>.
-

- have, say Y and find out whether you have one of the following
- drives.
-
- For each of these drivers, a <file:Documentation/cdrom/{driver_name}>
- exists. Especially in cases where you do not know exactly which kind
- of drive you have you should read there. Most of these drivers use a
- file drivers/cdrom/{driver_name}.h where you can define your

-
- To compile these CD-ROM drivers as a module, choose M instead of Y.
-
- If you want to use any of these CD-ROM drivers, you also have to
- answer Y or M to "ISO 9660 CD-ROM file system support" below (this

- "electrically compatible" drives (Vertos, Genoa, some Funai models)
- are currently not supported; for the Sanyo H94A drive currently a
- separate driver (asked later) is responsible. Most drives have a
- uniquely shaped faceplate, with a caddyless motorized drawer, but
- without external brand markings. The older CR-52x drives have a
- caddy and manual loading/eject, but still no external markings. The
- driver is able to do an extended auto-probing for interface
- addresses and drive types; this can help to find facts in cases you
- are not sure, but can consume some time during the boot process if
- none of the supported drives gets found. Once your drive got found,
- you should enter the reported parameters into
- <file:drivers/cdrom/sbpcd.h> and set "DISTRIBUTION 0" there.

- HISTORY
- V0.0 Adaption to Aztech CD268-01A Version 1.3
- Version is PRE_ALPHA, unresolved points:
- 1. I use busy wait instead of timer wait in STEN_LOW,DTEN_LOW
- thus driver causes CPU overhead and is very slow
- 2. could not find a way to stop the drive, when it is
- in data read mode, therefore I had to set
- msf.end.min/sec/frame to 0:0:1 (in azt_poll); so only one
- frame can be read in sequence, this is also the reason for
- 3. getting 'timeout in state 4' messages, but nevertheless
- it works
- W.Zimmermann, Oct. 31, 1994
- V0.1 Version is ALPHA, problems #2 and #3 resolved.
- W.Zimmermann, Nov. 3, 1994
- V0.2 Modification to some comments, debugging aids for partial test
- with Borland C under DOS eliminated. Timer interrupt wait
- STEN_LOW_WAIT additionally to busy wait for STEN_LOW implemented;
- use it only for the 'slow' commands (ACMD_GET_Q_CHANNEL, ACMD_
- SEEK_TO_LEAD_IN), all other commands are so 'fast', that busy
- waiting seems better to me than interrupt rescheduling.
- Besides that, when used in the wrong place, STEN_LOW_WAIT causes
- kernel panic.
- In function aztPlay command ACMD_PLAY_AUDIO added, should make
- audio functions work. The Aztech drive needs different commands
- to read data tracks and play audio tracks.
- W.Zimmermann, Nov. 8, 1994
- V0.3 Recognition of missing drive during boot up improved (speeded up).
- W.Zimmermann, Nov. 13, 1994
- V0.35 Rewrote the control mechanism in azt_poll (formerly mcd_poll)
- including removal of all 'goto' commands. :-);
- J. Nardone, Nov. 14, 1994
- V0.4 Renamed variables and constants to 'azt' instead of 'mcd'; had
- to make some "compatibility" defines in azt.h; please note,
- that the source file was renamed to azt.c, the include file to
- azt.h
- Speeded up drive recognition during init (will be a little bit
- slower than before if no drive is installed!); suggested by
- Robby Schirmer.
- read_count declared volatile and set to AZT_BUF_SIZ to make
- drive faster (now 300kB/sec, was 60kB/sec before, measured
- by 'time dd if=/dev/cdrom of=/dev/null bs=2048 count=4096';
- different AZT_BUF_SIZes were test, above 16 no further im-
- provement seems to be possible; suggested by E.Moenkeberg.
- W.Zimmermann, Nov. 18, 1994
- V0.42 Included getAztStatus command in GetQChannelInfo() to allow
- reading Q-channel info on audio disks, if drive is stopped,
- and some other bug fixes in the audio stuff, suggested by
- Robby Schirmer.
- Added more ioctls (reading data in mode 1 and mode 2).
- Completely removed the old azt_poll() routine.
- Detection of ORCHID CDS-3110 in aztcd_init implemented.
- Additional debugging aids (see the readme file).
- W.Zimmermann, Dec. 9, 1994
- V0.50 Autodetection of drives implemented.
- W.Zimmermann, Dec. 12, 1994
- V0.52 Prepared for including in the standard kernel, renamed most
- variables to contain 'azt', included autoconf.h
- W.Zimmermann, Dec. 16, 1994
- V0.6 Version for being included in the standard Linux kernel.
- Renamed source and header file to aztcd.c and aztcd.h
- W.Zimmermann, Dec. 24, 1994
- V0.7 Changed VERIFY_READ to VERIFY_WRITE in aztcd_ioctl, case
- CDROMREADMODE1 and CDROMREADMODE2; bug fix in the ioctl,
- which causes kernel crashes when playing audio, changed
- include-files (config.h instead of autoconf.h, removed
- delay.h)
- W.Zimmermann, Jan. 8, 1995
- V0.72 Some more modifications for adaption to the standard kernel.
- W.Zimmermann, Jan. 16, 1995
- V0.80 aztcd is now part of the standard kernel since version 1.1.83.
- Modified the SET_TIMER and CLEAR_TIMER macros to comply with
- the new timer scheme.
- W.Zimmermann, Jan. 21, 1995
- V0.90 Included CDROMVOLCTRL, but with my Aztech drive I can only turn
- the channels on and off. If it works better with your drive,
- please mail me. Also implemented ACMD_CLOSE for CDROMSTART.
- W.Zimmermann, Jan. 24, 1995
- V1.00 Implemented close and lock tray commands. Patches supplied by
- Frank Racis
- Added support for loadable MODULEs, so aztcd can now also be
- loaded by insmod and removed by rmmod during run time
- Werner Zimmermann, Mar. 24, 95
- V1.10 Implemented soundcard configuration for Orchid CDS-3110 drives
- connected to Soundwave32 cards. Release for LST 2.1.
- (still experimental)
- Werner Zimmermann, May 8, 95
- V1.20 Implemented limited support for DOSEMU0.60's cdrom.c. Now it works, but
- sometimes DOSEMU may hang for 30 seconds or so. A fully functional ver-
- sion needs an update of Dosemu0.60's cdrom.c, which will come with the
- next revision of Dosemu.
- Also Soundwave32 support now works.
- Werner Zimmermann, May 22, 95
- V1.30 Auto-eject feature. Inspired by Franc Racis (racis@psu.edu)
- Werner Zimmermann, July 4, 95
- V1.40 Started multisession support. Implementation copied from mcdx.c
- by Heiko Schlittermann. Not tested yet.
- Werner Zimmermann, July 15, 95
- V1.50 Implementation of ioctl CDROMRESET, continued multisession, began
- XA, but still untested. Heavy modifications to drive status de-
- tection.
- Werner Zimmermann, July 25, 95
- V1.60 XA support now should work. Speeded up drive recognition in cases,
- where no drive is installed.
- Werner Zimmermann, August 8, 1995
- V1.70 Multisession support now is completed, but there is still not
- enough testing done. If you can test it, please contact me. For
- details please read Documentation/cdrom/aztcd
- Werner Zimmermann, August 19, 1995
- V1.80 Modification to suit the new kernel boot procedure introduced
- with kernel 1.3.33. Will definitely not work with older kernels.
- Programming done by Linus himself.
- Werner Zimmermann, October 11, 1995
- V1.90 Support for Conrad TXC drives, thank's to Jochen Kunz and Olaf Kaluza.
- Werner Zimmermann, October 21, 1995
- V2.00 Changed #include "blk.h" to <linux/blk.h> as the directory
- structure was changed. README.aztcd is now /usr/src/docu-
- mentation/cdrom/aztcd
- Werner Zimmermann, November 10, 95
- V2.10 Started to modify azt_poll to prevent reading beyond end of
- tracks.
- Werner Zimmermann, December 3, 95
- V2.20 Changed some comments
- Werner Zimmermann, April 1, 96
- V2.30 Implemented support for CyCDROM CR520, CR940, Code for CR520
- delivered by H.Berger with preworks by E.Moenkeberg.
- Werner Zimmermann, April 29, 96
- V2.40 Reorganized the placement of functions in the source code file
- to reflect the layered approach; did not actually change code
- Werner Zimmermann, May 1, 96
- V2.50 Heiko Eissfeldt suggested to remove some VERIFY_READs in
- aztcd_ioctl; check_aztcd_media_change modified
- Werner Zimmermann, May 16, 96
- V2.60 Implemented Auto-Probing; made changes for kernel's 2.1.xx blocksize
- Adaption to linux kernel > 2.1.0
- Werner Zimmermann, Nov 29, 97
-
- November 1999 -- Make kernel-parameter implementation work with 2.3.x
- Removed init_module & cleanup_module in favor of
- module_init & module_exit.

-* Sony CDU-31A CDROM interface device driver.
-*
-* Corey Minyard (minyard@wf-rch.cirr.com)
-*
-* Colossians 3:17
-*
-* See Documentation/cdrom/cdu31a for additional details about this driver.
-*
-* The Sony interface device driver handles Sony interface CDROM
-* drives and provides a complete block-level interface as well as an
-* ioctl() interface compatible with the Sun (as specified in
-* include/linux/cdrom.h). With this interface, CDROMs can be
-* accessed and standard audio CDs can be played back normally.
-*
-* WARNING - All autoprobes have been removed from the driver.
-* You MUST configure the CDU31A via a LILO config
-* at boot time or in lilo.conf. I have the
-* following in my lilo.conf:
-*
-* append="cdu31a=0x1f88,0,PAS"
-*
-* The first number is the I/O base address of the
-* card. The second is the interrupt (0 means none).
- * The third should be "PAS" if on a Pro-Audio
- * spectrum, or nothing if on something else.
- *
- * This interface is (unfortunately) a polled interface. This is
- * because most Sony interfaces are set up with DMA and interrupts
- * disables. Some (like mine) do not even have the capability to
- * handle interrupts or DMA. For this reason you will see a lot of
- * the following:
- *
- * retry_count = jiffies+ SONY_JIFFIES_TIMEOUT;
- * while (time_before(jiffies, retry_count) && (! <some condition to wait for))
- * {
- * while (handle_sony_cd_attention())
- * ;
- *
- * sony_sleep();
- * }
- * if (the condition not met)
- * {
- * return an error;
- * }
- *
- * This ugly hack waits for something to happen, sleeping a little
- * between every try. it also handles attentions, which are
- * asynchronous events from the drive informing the driver that a disk
- * has been inserted, removed, etc.
- *
- * NEWS FLASH - The driver now supports interrupts but they are
- * turned off by default. Use of interrupts is highly encouraged, it
- * cuts CPU usage down to a reasonable level. I had DMA in for a while
- * but PC DMA is just too slow. Better to just insb() it.
- *
- * One thing about these drives: They talk in MSF (Minute Second Frame) format.
- * There are 75 frames a second, 60 seconds a minute, and up to 75 minutes on a
- * disk. The funny thing is that these are sent to the drive in BCD, but the
- * interface wants to see them in decimal. A lot of conversion goes on.
- *
- * DRIVER SPECIAL FEATURES
- * -----------------------
- *
- * This section describes features beyond the normal audio and CD-ROM
- * functions of the drive.
- *
- * XA compatibility
- *
- * The driver should support XA disks for both the CDU31A and CDU33A.
- * It does this transparently, the using program doesn't need to set it.
- *
- * Multi-Session
- *
- * A multi-session disk looks just like a normal disk to the user.
- * Just mount one normally, and all the data should be there.
- * A special thanks to Koen for help with this!
- *
- * Raw sector I/O
- *
- * Using the CDROMREADAUDIO it is possible to read raw audio and data
- * tracks. Both operations return 2352 bytes per sector. On the data
- * tracks, the first 12 bytes is not returned by the drive and the value
- * of that data is indeterminate.

- * TODO:
- * CDs with form1 and form2 sectors cause problems
- * with current read-ahead strategy.
- *
- * Credits:
- * Heiko Eissfeldt <heiko@colossus.escape.de>
- * For finding abug in the return of the track numbers.
- * TOC processing redone for proper multisession support.
- *
- *
- * It probably a little late to be adding a history, but I guess I
- * will start.
- *
- * 10/24/95 - Added support for disabling the eject button when the
- * drive is open. Note that there is a small problem
- * still here, if the eject button is pushed while the
- * drive light is flashing, the drive will return a bad
- * status and be reset. It recovers, though.
- *
- * 03/07/97 - Fixed a problem with timers.
- *
- *
- * 18 Spetember 1997 -- Ported to Uniform CD-ROM driver by
- * Heiko Eissfeldt <heiko@colossus.escape.de> with additional
- * changes by Erik Andersen <andersee@debian.org>
- *
- * 24 January 1998 -- Removed the scd_disc_status() function, which was now
- * just dead code left over from the port.
- * Erik Andersen <andersee@debian.org>
- *
- * 16 July 1998 -- Drive donated to Erik Andersen by John Kodis
- * <kodis@jagunet.com>. Work begun on fixing driver to
- * work under 2.1.X. Added temporary extra printks
- * which seem to slow it down enough to work.
- *
- * 9 November 1999 -- Make kernel-parameter implementation work with 2.3.x
- * Removed init_module & cleanup_module in favor of
- * module_init & module_exit.
- * Torben Mathiasen <tmm@image.dk>
- *
- * 22 October 2004 -- Make the driver work in 2.6.X
- * Added workaround to fix hard lockups on eject
- * Fixed door locking problem after mounting empty drive
- * Set double-speed drives to double speed by default
- * Removed all readahead things - not needed anymore
- * Ondrej Zary <rainbow@rainbow-software.org>

-History:
- Started 25 jan 1994. Waiting for documentation...
- 22 feb 1995: 0.1a first reasonably safe polling driver.
- Two major bugs, one in read_sector and one in
- do_cm206_request, happened to cancel!
- 25 feb 1995: 0.2a first reasonable interrupt driven version of above.
- uart writes are still done in polling mode.
- 25 feb 1995: 0.21a writes also in interrupt mode, still some
- small bugs to be found... Larger buffer.
- 2 mrt 1995: 0.22 Bug found (cd-> nowhere, interrupt was called in
- initialization), read_ahead of 16. Timeouts implemented.
- unclear if they do something...
- 7 mrt 1995: 0.23 Start of background read-ahead.
- 18 mrt 1995: 0.24 Working background read-ahead. (still problems)
- 26 mrt 1995: 0.25 Multi-session ioctl added (kernel v1.2).
- Statistics implemented, though separate stats206.h.
- Accessible through ioctl 0x1000 (just a number).
- Hard to choose between v1.2 development and 1.1.75.
- Bottom-half doesn't work with 1.2...
- 0.25a: fixed... typo. Still problems...
- 1 apr 1995: 0.26 Module support added. Most bugs found. Use kernel 1.2.n.
- 5 apr 1995: 0.27 Auto-probe for the adapter card base address.
- Auto-probe for the adaptor card irq line.
- 7 apr 1995: 0.28 Added lilo setup support for base address and irq.
- Use major number 32 (not in this source), officially
- assigned to this driver.
- 9 apr 1995: 0.29 Added very limited audio support. Toc_header, stop, pause,
- resume, eject. Play_track ignores track info, because we can't
- read a table-of-contents entry. Toc_entry is implemented
- as a `placebo' function: always returns start of disc.
- 3 may 1995: 0.30 Audio support completed. The get_toc_entry function
- is implemented as a binary search.
- 15 may 1995: 0.31 More work on audio stuff. Workman is not easy to
- satisfy; changed binary search into linear search.
- Auto-probe for base address somewhat relaxed.
- 1 jun 1995: 0.32 Removed probe_irq_on/off for module version.
- 10 jun 1995: 0.33 Workman still behaves funny, but you should be
- able to eject and substitute another disc.
-
- An adaptation of 0.33 is included in linux-1.3.7 by Eberhard Moenkeberg
-
- 18 jul 1995: 0.34 Patch by Heiko Eissfeldt included, mainly considering
- verify_area's in the ioctls. Some bugs introduced by
- EM considering the base port and irq fixed.
-
- 18 dec 1995: 0.35 Add some code for error checking... no luck...
-
- We jump to reach our goal: version 1.0 in the next stable linux kernel.
-
- 19 mar 1996: 0.95 Different implementation of CDROM_GET_UPC, on
- request of Thomas Quinot.
- 25 mar 1996: 0.96 Interpretation of opening with O_WRONLY or O_RDWR:
- open only for ioctl operation, e.g., for operation of
- tray etc.
- 4 apr 1996: 0.97 First implementation of layer between VFS and cdrom
- driver, a generic interface. Much of the functionality
- of cm206_open() and cm206_ioctl() is transferred to a
- new file cdrom.c and its header ucdrom.h.
-
- Upgrade to Linux kernel 1.3.78.
-
- 11 apr 1996 0.98 Upgrade to Linux kernel 1.3.85
- More code moved to cdrom.c
-
- 0.99 Some more small changes to decrease number
- of oopses at module load;
-
- 27 jul 1996 0.100 Many hours of debugging, kernel change from 1.2.13
- to 2.0.7 seems to have introduced some weird behavior
- in (interruptible_)sleep_on(&cd->data): the process
- seems to be woken without any explicit wake_up in my own
- code. Patch to try 100x in case such untriggered wake_up's
- occur.
-
- 28 jul 1996 0.101 Rewriting of the code that receives the command echo,
- using a fifo to store echoed bytes.
-
- Branch from 0.99:
-
- 0.99.1.0 Update to kernel release 2.0.10 dev_t -> kdev_t
- (emoenke) various typos found by others. extra
- module-load oops protection.
-
- 0.99.1.1 Initialization constant cdrom_dops.speed
- changed from float (2.0) to int (2); Cli()-sti() pair
- around cm260_reset() in module initialization code.
-
- 0.99.1.2 Changes literally as proposed by Scott Snyder
- <snyder@d0sgif.fnal.gov> for the 2.1 kernel line, which
- have to do mainly with the poor minor support i had. The
- major new concept is to change a cdrom driver's
- operations struct from the capabilities struct. This
- reflects the fact that there is one major for a driver,
- whilst there can be many minors whith completely
- different capabilities.
-
- 0.99.1.3 More changes for operations/info separation.
-
- 0.99.1.4 Added speed selection (someone had to do this
- first).
-
- 23 jan 1997 0.99.1.5 MODULE_PARMS call added.
-
- 23 jan 1997 0.100.1.2--0.100.1.5 following similar lines as
- 0.99.1.1--0.99.1.5. I get too many complaints about the
- drive making read errors. What't wrong with the 2.0+
- kernel line? Why get i (and othe cm206 owners) weird
- results? Why were things good in the good old 1.1--1.2
- era? Why don't i throw away the drive?
-
- 2 feb 1997 0.102 Added `volatile' to values in cm206_struct. Seems to
- reduce many of the problems. Rewrote polling routines
- to use fixed delays between polls.
- 0.103 Changed printk behavior.
- 0.104 Added a 0.100 -> 0.100.1.1 change
-
-11 feb 1997 0.105 Allow auto_probe during module load, disable
- with module option "auto_probe=0". Moved some debugging
- statements to lower priority. Implemented select_speed()
- function.
-
-13 feb 1997 1.0 Final version for 2.0 kernel line.
-
- All following changes will be for the 2.1 kernel line.
-
-15 feb 1997 1.1 Keep up with kernel 2.1.26, merge in changes from
- cdrom.c 0.100.1.1--1.0. Add some more MODULE_PARMS.
-
-14 sep 1997 1.2 Upgrade to Linux 2.1.55. Added blksize_size[], patch
- sent by James Bottomley <James.Bottomley@columbiasc.ncr.com>.
-
-21 dec 1997 1.4 Upgrade to Linux 2.1.72.
-
-24 jan 1998 Removed the cm206_disc_status() function, as it was now dead
- code. The Uniform CDROM driver now provides this functionality.
-
-9 Nov. 1999 Make kernel-parameter implementation work with 2.3.x
- Removed init_module & cleanup_module in favor of
- module_init & module_exit.
- Torben Mathiasen <tmm@image.dk>
- *
- * Parts of the code are based upon lmscd.c written by Kai Petzke,
- * sbpcd.c written by Eberhard Moenkeberg, and mcd.c by Martin
- * Harriss, but any off-the-shelf dynamic programming algorithm won't
- * be able to find them.
- *
- * The cm206 drive interface and the cm260 adapter card seem to be
- * sufficiently different from their cm205/cm250 counterparts
- * in order to write a complete new driver.
- *
- * I call all routines connected to the Linux kernel something
- * with `cm206' in it, as this stuff is too series-dependent.
- *
- * Currently, my limited knowledge is based on:
- * - The Linux Kernel Hacker's guide, v. 0.5, by Michael K. Johnson
- * - Linux Kernel Programmierung, by Michael Beck and others
- * - Philips/LMS cm206 and cm226 product specification
- * - Philips/LMS cm260 product specification

-/* Revision history
-
-
- 14-5-95 v0.0 Plays sound tracks. No reading of data CDs yet.
- Detection of disk change doesn't work.
- 21-5-95 v0.1 First ALPHA version. CD can be mounted. The
- device major nr is borrowed from the Aztech
- driver. Speed is around 240 kb/s, as measured
- with "time dd if=/dev/cdrom of=/dev/null \
- bs=2048 count=4096".
- 24-6-95 v0.2 Reworked the #defines for the command codes
- and the like, as well as the structure of
- the hardware communication protocol, to
- reflect the "official" documentation, kindly
- supplied by C.K. Tan, Optics Storage Pte. Ltd.
- Also tidied up the state machine somewhat.
- 28-6-95 v0.3 Removed the ISP-16 interface code, as this
- should go into its own driver. The driver now
- has its own major nr.
- Disk change detection now seems to work, too.
- This version became part of the standard
- kernel as of version 1.3.7
- 24-9-95 v0.4 Re-inserted ISP-16 interface code which I
- copied from sjcd.c, with a few changes.
- Updated README.optcd. Submitted for
- inclusion in 1.3.21
- 29-9-95 v0.4a Fixed bug that prevented compilation as module
- 25-10-95 v0.5 Started multisession code. Implementation
- copied from Werner Zimmermann, who copied it
- from Heiko Schlittermann's mcdx.
- 17-1-96 v0.6 Multisession works; some cleanup too.
- 18-4-96 v0.7 Increased some timing constants;
- thanks to Luke McFarlane. Also tidied up some
- printk behaviour. ISP16 initialization
- is now handled by a separate driver.
-
- 09-11-99 Make kernel-parameter implementation work with 2.3.x
- Removed init_module & cleanup_module in favor of
- module_init & module_exit.

- * VERSION HISTORY
- *
- * 0.1 initial release, April/May 93, after mcd.c (Martin Harriss)
- *
- * 0.2 thek "repeat:"-loop in do_sbpcd_request did not check for
- * end-of-request_queue (resulting in kernel panic).
- * Flow control seems stable, but throughput is not better.
- *
- * 0.3 interrupt locking totally eliminated (maybe "inb" and "outb"
- * are still locking) - 0.2 made keyboard-type-ahead losses.
- * check_sbpcd_media_change added (to use by isofs/inode.c)
- * - but it detects almost nothing.
- *
- * 0.4 use MAJOR 25 definitely.
- * Almost total re-design to support double-speed drives and
- * "naked" (no sound) interface cards ("LaserMate" interface type).
- * Flow control should be exact now.
- * Don't occupy the SbPro IRQ line (not needed either); will
- * live together with Hannu Savolainen's sndkit now.
- * Speeded up data transfer to 150 kB/sec, with help from Kai
- * Makisara, the "provider" of the "mt" tape utility.
- * Give "SpinUp" command if necessary.
- * First steps to support up to 4 drives (but currently only one).
- * Implemented audio capabilities - workman should work, xcdplayer
- * gives some problems.
- * This version is still consuming too much CPU time, and
- * sleeping still has to be worked on.
- * During "long" implied seeks, it seems possible that a
- * ReadStatus command gets ignored. That gives the message
- * "ResponseStatus timed out" (happens about 6 times here during
- * a "ls -alR" of the YGGDRASIL LGX-Beta CD). Such a case is
- * handled without data error, but it should get done better.
- *
- * 0.5 Free CPU during waits (again with help from Kai Makisara).
- * Made it work together with the LILO/kernel setup standard.
- * Included auto-probing code, as suggested by YGGDRASIL.
- * Formal redesign to add DDI debugging.
- * There are still flaws in IOCTL (workman with double speed drive).
- *
- * 1.0 Added support for all drive IDs (0...3, no longer only 0)
- * and up to 4 drives on one controller.
- * Added "#define MANY_SESSION" for "old" multi session CDs.
- *
- * 1.1 Do SpinUp for new drives, too.
- * Revised for clean compile under "old" kernels (0.99pl9).
- *
- * 1.2 Found the "workman with double-speed drive" bug: use the driver's
- * audio_state, not what the drive is reporting with ReadSubQ.
- *
- * 1.3 Minor cleanups.
- * Refinements regarding Workman.
- *
- * 1.4 Read XA disks (PhotoCDs) with "old" drives, too (but only the first
- * session - no chance to fully access a "multi-session" CD).
- * This currently still is too slow (50 kB/sec) - but possibly
- * the old drives won't do it faster.
- * Implemented "door (un)lock" for new drives (still does not work
- * as wanted - no lock possible after an unlock).
- * Added some debugging printout for the UPC/EAN code - but my drives
- * return only zeroes. Is there no UPC/EAN code written?
- *
- * 1.5 Laborate with UPC/EAN code (not better yet).
- * Adapt to kernel 1.1.8 change (have to explicitly include
- * <linux/string.h> now).
- *
- * 1.6 Trying to read audio frames as data. Impossible with the current
- * drive firmware levels, as it seems. Awaiting any hint. ;-)
- * Changed "door unlock": repeat it until success.
- * Changed CDROMSTOP routine (stop somewhat "softer" so that Workman
- * won't get confused).
- * Added a third interface type: Sequoia S-1000, as used with the SPEA
- * Media FX sound card. This interface (usable for Sony and Mitsumi
- * drives, too) needs a special configuration setup and behaves like a
- * LaserMate type after that. Still experimental - I do not have such
- * an interface.
- * Use the "variable BLOCK_SIZE" feature (2048). But it does only work
- * if you give the mount option "block=2048".
- * The media_check routine is currently disabled; now that it gets
- * called as it should I fear it must get synchronized for not to
- * disturb the normal driver's activity.
- *
- * 2.0 Version number bumped - two reasons:
- * - reading audio tracks as data works now with CR-562 and CR-563. We
- * currently do it by an IOCTL (yet has to get standardized), one frame
- * at a time; that is pretty slow. But it works.
- * - we are maintaining now up to 4 interfaces (each up to 4 drives):
- * did it the easy way - a different MAJOR (25, 26, ...) and a different
- * copy of the driver (sbpcd.c, sbpcd2.c, sbpcd3.c, sbpcd4.c - only
- * distinguished by the value of SBPCD_ISSUE and the driver's name),
- * and a common sbpcd.h file.
- * Bettered the "ReadCapacity error" problem with old CR-52x drives (the
- * drives sometimes need a manual "eject/insert" before work): just
- * reset the drive and do again. Needs lots of resets here and sometimes
- * that does not cure, so this can't be the solution.
- *
- * 2.1 Found bug with multisession CDs (accessing frame 16).
- * "read audio" works now with address type CDROM_MSF, too.
- * Bigger audio frame buffer: allows reading max. 4 frames at time; this
- * gives a significant speedup, but reading more than one frame at once
- * gives missing chunks at each single frame boundary.
- *
- * 2.2 Kernel interface cleanups: timers, init, setup, media check.
- *
- * 2.3 Let "door lock" and "eject" live together.
- * Implemented "close tray" (done automatically during open).
- *
- * 2.4 Use different names for device registering.
- *
- * 2.5 Added "#if EJECT" code (default: enabled) to automatically eject
- * the tray during last call to "sbpcd_release".
- * Added "#if JUKEBOX" code (default: disabled) to automatically eject
- * the tray during call to "sbpcd_open" if no disk is in.
- * Turn on the CD volume of "compatible" sound cards, too; just define
- * SOUND_BASE (in sbpcd.h) accordingly (default: disabled).
- *
- * 2.6 Nothing new.
- *
- * 2.7 Added CDROMEJECT_SW ioctl to set the "EJECT" behavior on the fly:
- * 0 disables, 1 enables auto-ejecting. Useful to keep the tray in
- * during shutdown.
- *
- * 2.8 Added first support (still BETA, I need feedback or a drive) for
- * the Longshine LCS-7260 drives. They appear as double-speed drives
- * using the "old" command scheme, extended by tray control and door
- * lock functions.
- * Found (and fixed preliminary) a flaw with some multisession CDs: we
- * have to re-direct not only the accesses to frame 16 (the isofs
- * routines drive it up to max. 100), but also those to the continuation
- * (repetition) frames (as far as they exist - currently set fix as
- * 16..20).
- * Changed default of the "JUKEBOX" define. If you use this default,
- * your tray will eject if you try to mount without a disk in. Next
- * mount command will insert the tray - so, just fill in a disk. ;-)
- *
- * 2.9 Fulfilled the Longshine LCS-7260 support; with great help and
- * experiments by Serge Robyns.
- * First attempts to support the TEAC CD-55A drives; but still not
- * usable yet.
- * Implemented the CDROMMULTISESSION ioctl; this is an attempt to handle
- * multi session CDs more "transparent" (redirection handling has to be
- * done within the isofs routines, and only for the special purpose of
- * obtaining the "right" volume descriptor; accesses to the raw device
- * should not get redirected).
- *
- * 3.0 Just a "normal" increment, with some provisions to do it better. ;-)
- * Introduced "#define READ_AUDIO" to specify the maximum number of
- * audio frames to grab with one request. This defines a buffer size
- * within kernel space; a value of 0 will reserve no such space and
- * disable the CDROMREADAUDIO ioctl. A value of 75 enables the reading
- * of a whole second with one command, but will use a buffer of more
- * than 172 kB.
- * Started CD200 support. Drive detection should work, but nothing
- * more.
- *
- * 3.1 Working to support the CD200 and the Teac CD-55A drives.
- * AT-BUS style device numbering no longer used: use SCSI style now.
- * So, the first "found" device has MINOR 0, regardless of the
- * jumpered drive ID. This implies modifications to the /dev/sbpcd*
- * entries for some people, but will help the DAU (german TLA, english:
- * "newbie", maybe ;-) to install his "first" system from a CD.
- *
- * 3.2 Still testing with CD200 and CD-55A drives.
- *
- * 3.3 Working with CD200 support.
- *
- * 3.4 Auto-probing stops if an address of 0 is seen (to be entered with
- * the kernel command line).
- * Made the driver "loadable". If used as a module, "audio copy" is
- * disabled, and the internal read ahead data buffer has a reduced size
- * of 4 kB; so, throughput may be reduced a little bit with slow CPUs.
- *
- * 3.5 Provisions to handle weird photoCDs which have an interrupted
- * "formatting" immediately after the last frames of some files: simply
- * never "read ahead" with MultiSession CDs. By this, CPU usage may be
- * increased with those CDs, and there may be a loss in speed.
- * Re-structured the messaging system.
- * The "loadable" version no longer has a limited READ_AUDIO buffer
- * size.
- * Removed "MANY_SESSION" handling for "old" multi session CDs.
- * Added "private" IOCTLs CDROMRESET and CDROMVOLREAD.
- * Started again to support the TEAC CD-55A drives, now that I found
- * the money for "my own" drive. ;-)
- * The TEAC CD-55A support is fairly working now.
- * I have measured that the drive "delivers" at 600 kB/sec (even with
- * bigger requests than the drive's 64 kB buffer can satisfy), but
- * the "real" rate does not exceed 520 kB/sec at the moment.
- * Caused by the various changes to build in TEAC support, the timed
- * loops are de-optimized at the moment (less throughput with CR-52x
- * drives, and the TEAC will give speed only with SBP_BUFFER_FRAMES 64).
- *
- * 3.6 Fixed TEAC data read problems with SbPro interfaces.
- * Initial size of the READ_AUDIO buffer is 0. Can get set to any size
- * during runtime.
- *
- * 3.7 Introduced MAX_DRIVES for some poor interface cards (seen with TEAC
- * drives) which allow only one drive (ID 0); this avoids repetitive
- * detection under IDs 1..3.
- * Elongated cmd_out_T response waiting; necessary for photo CDs with
- * a lot of sessions.
- * Bettered the sbpcd_open() behavior with TEAC drives.
- *
- * 3.8 Elongated max_latency for CR-56x drives.
- *
- * 3.9 Finally fixed the long-known SoundScape/SPEA/Sequoia S-1000 interface
- * configuration bug.
- * Now Corey, Heiko, Ken, Leo, Vadim/Eric & Werner are invited to copy
- * the config_spea() routine into their drivers. ;-)
- *
- * 4.0 No "big step" - normal version increment.
- * Adapted the benefits from 1.3.33.
- * Fiddled with CDROMREADAUDIO flaws.
- * Avoid ReadCapacity command with CD200 drives (the MKE 1.01 version
- * seems not to support it).
- * Fulfilled "read audio" for CD200 drives, with help of Pete Heist
- * (heistp@rpi.edu).
- *
- * 4.1 Use loglevel KERN_INFO with printk().
- * Added support for "Vertos 100" drive ("ECS-AT") - it is very similar
- * to the Longshine LCS-7260. Give feedback if you can - I never saw
- * such a drive, and I have no specs.
- *
- * 4.2 Support for Teac 16-bit interface cards. Can't get auto-detected,
- * so you have to jumper your card to 0x2C0. Still not 100% - come
- * in contact if you can give qualified feedback.
- * Use loglevel KERN_NOTICE with printk(). If you get annoyed by a
- * flood of unwanted messages and the accompanied delay, try to read
- * my documentation. Especially the Linux CDROM drivers have to do an
- * important job for the newcomers, so the "distributed" version has
- * to fit some special needs. Since generations, the flood of messages
- * is user-configurable (even at runtime), but to get aware of this, one
- * needs a special mental quality: the ability to read.
- *
- * 4.3 CD200F does not like to receive a command while the drive is
- * reading the ToC; still trying to solve it.
- * Removed some redundant verify_area calls (yes, Heiko Eissfeldt
- * is visiting all the Linux CDROM drivers ;-).
- *
- * 4.4 Adapted one idea from tiensivu@pilot.msu.edu's "stripping-down"
- * experiments: "KLOGD_PAUSE".
- * Inhibited "play audio" attempts with data CDs. Provisions for a
- * "data-safe" handling of "mixed" (data plus audio) Cds.
- *
- * 4.5 Meanwhile Gonzalo Tornaria <tornaria@cmat.edu.uy> (GTL) built a
- * special end_request routine: we seem to have to take care for not
- * to have two processes working at the request list. My understanding
- * was and is that ll_rw_blk should not call do_sbpcd_request as long
- * as there is still one call active (the first call will care for all
- * outstanding I/Os, and if a second call happens, that is a bug in
- * ll_rw_blk.c).
- * "Check media change" without touching any drive.
- *
- * 4.6 Use a semaphore to synchronize multi-activity; elaborated by Rob
- * Riggs <rriggs@tesser.com>. At the moment, we simply block "read"
- * against "ioctl" and vice versa. This could be refined further, but
- * I guess with almost no performance increase.
- * Experiments to speed up the CD-55A; again with help of Rob Riggs
- * (to be true, he gave both, idea & code. ;-)
- *
- * 4.61 Ported to Uniform CD-ROM driver by
- * Heiko Eissfeldt <heiko@colossus.escape.de> with additional
- * changes by Erik Andersen <andersee@debian.org>
- *
- * 4.62 Fix a bug where playing audio left the drive in an unusable state.
- * Heiko Eissfeldt <heiko@colossus.escape.de>
- *
- * November 1999 -- Make kernel-parameter implementation work with 2.3.x
- * Removed init_module & cleanup_module in favor of
- * module_init & module_exit.
- * Torben Mathiasen <tmm@image.dk>
- *
- * 4.63 Bug fixes for audio annoyances, new legacy CDROM maintainer.
- * Annoying things fixed:
- * TOC reread on automated disk changes
- * TOC reread on manual cd changes
- * Play IOCTL tries to play CD before it's actually ready... sometimes.
- * CD_AUDIO_COMPLETED state so workman (and other playes) can repeat play.
- * Andrew J. Kroll <ag784@freenet.buffalo.edu> Wed Jul 26 04:24:10 EDT 2000
- *
- * 4.64 Fix module parameters - were being completely ignored.
- * Can also specify max_drives=N as a setup int to get rid of
- * "ghost" drives on crap hardware (aren't they all?) Paul Gortmaker
- *
- * TODO
- * implement "read all subchannel data" (96 bytes per frame)
- * remove alot of the virtual status bits and deal with hardware status
- * move the change of cd for audio to a better place
- * add debug levels to insmod parameters (trivial)
- *
- * special thanks to Kai Makisara (kai.makisara@vtt.fi) for his fine
- * elaborated speed-up experiments (and the fabulous results!), for
- * the "push" towards load-free wait loops, and for the extensive mail
- * thread which brought additional hints and bug fixes.

-/*
- * Attention! This file contains user-serviceable parts!
- * I recommend to make use of it...
- * If you feel helpless, look into Documentation/cdrom/sbpcd
- * (good idea anyway, at least before mailing me).
- *
- * The definitions for the first controller can get overridden by
- * the kernel command line ("lilo boot option").
- * Examples:
- * sbpcd=0x300,LaserMate
- * or
- * sbpcd=0x230,SoundBlaster
- * or
- * sbpcd=0x338,SoundScape
- * or
- * sbpcd=0x2C0,Teac16bit
- *
- * If sbpcd gets used as a module, you can load it with
- * insmod sbpcd.o sbpcd=0x300,0
- * or
- * insmod sbpcd.o sbpcd=0x230,1
- * or
- * insmod sbpcd.o sbpcd=0x338,2
- * or
- * insmod sbpcd.o sbpcd=0x2C0,3
- * respective to override the configured address and type.

-/*
- * define your CDROM port base address as CDROM_PORT
- * and specify the type of your interface card as SBPRO.
- *
- * address:
- * ========
- * SBPRO type addresses typically are 0x0230 (=0x220+0x10), 0x0250, ...
- * LASERMATE type (CI-101P, WDH-7001C) addresses typically are 0x0300, ...
- * SOUNDSCAPE addresses are from the LASERMATE type and range. You have to
- * specify the REAL address here, not the configuration port address. Look
- * at the CDROM driver's invoking line within your DOS CONFIG.SYS, or let
- * sbpcd auto-probe, if you are not firm with the address.
- * There are some soundcards on the market with 0x0630, 0x0650, ...; their
- * type is not obvious (both types are possible).
- *
- * example: if your SBPRO audio address is 0x220, specify 0x230 and SBPRO 1.
- * if your soundcard has its CDROM port above 0x300, specify
- * that address and try SBPRO 0 first.
- * if your SoundScape configuration port is at 0x330, specify
- * 0x338 and SBPRO 2.
- *
- * interface type:
- * ===============
- * set SBPRO to 1 for "true" SoundBlaster card
- * set SBPRO to 0 for "compatible" soundcards and
- * for "poor" (no sound) interface cards.
- * set SBPRO to 2 for Ensonic SoundScape or SPEA Media FX cards
- * set SBPRO to 3 for Teac 16bit interface cards
- *
- * Almost all "compatible" sound boards need to set SBPRO to 0.
- * If SBPRO is set wrong, the drives will get found - but any
- * data access will give errors (audio access will work).
- * The "OmniCD" no-sound interface card from CreativeLabs and most Teac
- * interface cards need SBPRO 1.
- *
- * sound base:
- * ===========
- * The SOUND_BASE definition tells if we should try to turn the CD sound
- * channels on. It will only be of use regarding soundcards with a SbPro
- * compatible mixer.
- *
- * Example: #define SOUND_BASE 0x220 enables the sound card's CD channels
- * #define SOUND_BASE 0 leaves the soundcard untouched

- * Copyright (C) 1995 Vadim V. Model
- *
- * model@cecmow.enet.dec.com
- * vadim@rbrf.ru
- * vadim@ipsun.ras.ru
- *
- *
- * This driver is based on pre-works by Eberhard Moenkeberg (emoenke@gwdg.de);
- * it was developed under use of mcd.c from Martin Harriss, with help of
- * Eric van der Maarel (H.T.M.v.d.Maarel@marin.nl).
- *
- * It is planned to include these routines into sbpcd.c later - to make
- * a "mixed use" on one cable possible for all kinds of drives which use
- * the SoundBlaster/Panasonic style CDROM interface. But today, the
- * ability to install directly from CDROM is more important than flexibility.

- *
- * History:
- * 1.1 First public release with kernel version 1.3.7.
- * Written by Vadim Model.
- * 1.2 Added detection and configuration of cdrom interface
- * on ISP16 soundcard.
- * Allow for command line options: sjcd=<io_base>,<irq>,<dma>
- * 1.3 Some minor changes to README.sjcd.
- * 1.4 MSS Sound support!! Listen to a CD through the speakers.
- * 1.5 Module support and bugfixes.
- * Tray locking.
- * 1.6 Removed ISP16 code from this driver.
- * Allow only to set io base address on command line: sjcd=<io_base>
- * Changes to Documentation/cdrom/sjcd
- * Added cleanup after any error in the initialisation.
- * 1.7 Added code to set the sector size tables to prevent the bug present in
- * the previous version of this driver. Coded added by Anthony Barbachan
- * from bugfix tip originally suggested by Alan Cox.
- *
- * November 1999 -- Make kernel-parameter implementation work with 2.3.x
- * Removed init_module & cleanup_module in favor of
- * module_init & module_exit.
- * Torben Mathiasen <tmm@image.dk>

- * Sony CDU-535 interface device driver
- *
- * This is a modified version of the CDU-31A device driver (see below).
- * Changes were made using documentation for the CDU-531 (which Sony
- * assures me is very similar to the 535) and partial disassembly of the
- * DOS driver. I used Minyard's driver and replaced the CDU-31A
- * commands with the CDU-531 commands. This was complicated by a different
- * interface protocol with the drive. The driver is still polled.
- *
- * Data transfer rate is about 110 Kb/sec, theoretical maximum is 150 Kb/sec.
- * I tried polling without the sony_sleep during the data transfers but
- * it did not speed things up any.
- *
- * 1993-05-23 (rgj) changed the major number to 21 to get rid of conflict
- * with CDU-31A driver. This is the also the number from the Linux
- * Device Driver Registry for the Sony Drive. Hope nobody else is using it.
- *
- * 1993-08-29 (rgj) remove the configuring of the interface board address
- * from the top level configuration, you have to modify it in this file.
- *
- * 1995-01-26 Made module-capable (Joel Katz <Stimpson@Panix.COM>)
- *
- * 1995-05-20
- * Modified to support CDU-510/515 series
- * (Claudio Porfiri<C.Porfiri@nisms.tei.ericsson.se>)
- * Fixed to report verify_area() failures
- * (Heiko Eissfeldt <heiko@colossus.escape.de>)
- *
- * 1995-06-01
- * More changes to support CDU-510/515 series
- * (Claudio Porfiri<C.Porfiri@nisms.tei.ericsson.se>)
- *
- * November 1999 -- Make kernel-parameter implementation work with 2.3.x
- * Removed init_module & cleanup_module in favor of
- * module_init & module_exit.
- * Torben Mathiasen <tmm@image.dk>
- *
- * September 2003 - Fix SMP support by removing cli/sti calls.
- * Using spinlocks with a wait_queue instead.
- * Felipe Damasio <felipewd@terra.com.br>
- *
- * Things to do:
- * - handle errors and status better, put everything into a single word
- * - use interrupts (code mostly there, but a big hole still missing)
- * - handle multi-session CDs?
- * - use DMA?
- *
- * Known Bugs:

- *------------------------------------------------------------------------
- * Sony CDROM interface device driver.
- *
- * Corey Minyard (minyard@wf-rch.cirr.com) (CDU-535 complaints to Ken above)
- *
- * Colossians 3:17
- *
- * The Sony interface device driver handles Sony interface CDROM
- * drives and provides a complete block-level interface as well as an
- * ioctl() interface compatible with the Sun (as specified in
- * include/linux/cdrom.h). With this interface, CDROMs can be
- * accessed and standard audio CDs can be played back normally.
- *
- * This interface is (unfortunately) a polled interface. This is
- * because most Sony interfaces are set up with DMA and interrupts
- * disables. Some (like mine) do not even have the capability to
- * handle interrupts or DMA. For this reason you will see a bit of
- * the following:
- *
- * snap = jiffies;
- * while (jiffies-snap < SONY_JIFFIES_TIMEOUT)
- * {
- * if (some_condition())
- * break;
- * sony_sleep();
- * }
- * if (some_condition not met)
- * {
- * return an_error;
- * }
- *
- * This ugly hack waits for something to happen, sleeping a little
- * between every try. (The conditional is written so that jiffies
- * wrap-around is handled properly.)
- *
- * One thing about these drives: They talk in MSF (Minute Second Frame) format.
- * There are 75 frames a second, 60 seconds a minute, and up to 75 minutes on a
- * disk. The funny thing is that these are sent to the drive in BCD, but the
- * interface wants to see them in decimal. A lot of conversion goes on.

+ This is the "Juju" FireWire stack, a new alternative implementation

or both.
+ To compile this driver as a module, say M here: the module will be
+ called firewire-core. It functionally replaces ieee1394, raw1394,
+ and video1394.
+
+ NOTE:
+
+ You should only build ONE of the stacks, unless you REALLY know what
+ you are doing. If you install both, you should configure them only as
+ modules rather than link them statically, and you should blacklist one
+ of the concurrent low-level drivers in /etc/modprobe.conf. Add either

+ blacklist firewire-ohci
+ or
+ blacklist ohci1394
+
+ there depending on which driver you DON'T want to have auto-loaded.
+ You can optionally do the same with the other IEEE 1394/ FireWire
+ drivers.
+
+ If you have an old modprobe which doesn't implement the blacklist
+ directive, use either
+
+ install firewire-ohci /bin/true
+ or
+ install ohci1394 /bin/true
+

+ * The DS1682 elapsed timer recorder is a simple device that implements

+ * bytes of general purpose EEPROM.
+ *
+ * This driver provides access to the DS1682 counters and user data via
+ * the sysfs. The following attributes are added to the device node:
+ * elapsed_time (u32): Total elapsed event time in ms resolution
+ * alarm_time (u32): When elapsed time exceeds the value in alarm_time,
+ * then the alarm pin is asserted.
+ * event_count (u16): number of times the event pin has gone low.
+ * eeprom (u8[10]): general purpose EEPROM
+ *
+ * Counter registers and user data are both read/write unless the device
+ * has been write protected. This driver does not support turning off write
+ * protection. Once write protection is turned on, it is impossible to
+ * turn it off again, so I have left the feature out of this driver to avoid
+ * accidental enabling, but it is trivial to add write protect support.

+ This driver simulates a mouse on GPIO lines of various CPUs (and some
+ other chips).
+
+ Say Y here if your device has buttons or a simple joystick connected
+ directly to GPIO lines. Your board-specific setup logic must also

+ used.

+ munged into HPPA boxen .
+
+ This driver is based upon 82596.c, original credits are below...
+ but there were too many hoops which HP wants jumped through to
+ keep this code in there in a sane manner.
+
+ 3 primary sources of the mess --
+ 1) hppa needs *lots* of cacheline flushing to keep this kind of
+ MMIO running.
+
+ 2) The 82596 needs to see all of its pointers as their physical
+ address. Thus virt_to_bus/bus_to_virt are *everywhere*.
+
+ 3) The implementation HP is using seems to be significantly pickier
+ about when and how the command and RX units are started. some
+ command ordering was changed.
+
+ Examination of the mach driver leads one to believe that there
+ might be a saner way to pull this off... anyone who feels like a
+ full rewrite can be my guest.

+/* 82596.c: A generic 82596 ethernet driver for linux. */
+/*
+ Based on Apricot.c
+ Written 1994 by Mark Evans.
+ This driver is for the Apricot 82596 bus-master interface
+
+ Modularised 12/94 Mark Evans
+
+
+ Modified to support the 82596 ethernet chips on 680x0 VME boards.
+ by Richard Hirst <richard@sleepie.demon.co.uk>
+ Renamed to be 82596.c
+
+ 980825: Changed to receive directly in to sk_buffs which are
+ allocated at open() time. Eliminates copy on incoming frames
+ (small ones are still copied). Shared data now held in a
+ non-cached page, so we can run on 68060 in copyback mode.
+
+ TBD:
+ * look at deferring rx frames rather than discarding (as per tulip)
+ * handle tx ring full as per tulip
+ * performace test to tune rx_copybreak
+
+ Most of my modifications relate to the braindead big-endian
+ implementation by Intel. When the i596 is operating in
+ 'big-endian' mode, it thinks a 32 bit value of 0x12345678
+ should be stored as 0x56781234. This is a real pain, when
+ you have linked lists which are shared by the 680x0 and the
+ i596.

+
+/* This driver handles only L2TP data frames; control frames are handled by a
+ * userspace application.
+ *
+ * To send data in an L2TP session, userspace opens a PPPoL2TP socket and
+ * attaches it to a bound UDP socket with local tunnel_id / session_id and
+ * peer tunnel_id / session_id set. Data can then be sent or received using
+ * regular socket sendmsg() / recvmsg() calls. Kernel parameters of the socket
+ * can be read or modified using ioctl() or [gs]etsockopt() calls.
+ *
+ * When a PPPoL2TP socket is connected with local and peer session_id values
+ * zero, the socket is treated as a special tunnel management socket.
+ *
+ * Here's example userspace code to create a socket for sending/receiving data
+ * over an L2TP session:-
+ *
+ * struct sockaddr_pppol2tp sax;
+ * int fd;
+ * int session_fd;
+ *
+ * fd = socket(AF_PPPOX, SOCK_DGRAM, PX_PROTO_OL2TP);
+ *
+ * sax.sa_family = AF_PPPOX;
+ * sax.sa_protocol = PX_PROTO_OL2TP;
+ * sax.pppol2tp.fd = tunnel_fd; // bound UDP socket
+ * sax.pppol2tp.addr.sin_addr.s_addr = addr->sin_addr.s_addr;
+ * sax.pppol2tp.addr.sin_port = addr->sin_port;
+ * sax.pppol2tp.addr.sin_family = AF_INET;
+ * sax.pppol2tp.s_tunnel = tunnel_id;
+ * sax.pppol2tp.s_session = session_id;
+ * sax.pppol2tp.d_tunnel = peer_tunnel_id;
+ * sax.pppol2tp.d_session = peer_session_id;
+ *
+ * session_fd = connect(fd, (struct sockaddr *)&sax, sizeof(sax));
+ *
+ * A pppd plugin that allows PPP traffic to be carried over L2TP using
+ * this driver is available from the OpenL2TP project at
+ * http://openl2tp.sourceforge.net.

-=========================================================================
- r8169.c: A RealTek RTL-8169 Gigabit Ethernet driver for Linux kernel 2.4.x.
- --------------------------------------------------------------------
-
- History:
- Feb 4 2002 - created initially by ShuChen <shuchen@realtek.com.tw>.
- May 20 2002 - Add link status force-mode and TBI mode support.
- 2004 - Massive updates. See kernel SCM system for details.
-=========================================================================
- 1. [DEPRECATED: use ethtool instead] The media can be forced in 5 modes.
- Command: 'insmod r8169 media = SET_MEDIA'
- Ex: 'insmod r8169 media = 0x04' will force PHY to operate in 100Mpbs Half-duplex.
-
- SET_MEDIA can be:
- _10_Half = 0x01
- _10_Full = 0x02
- _100_Half = 0x04
- _100_Full = 0x08
- _1000_Full = 0x10
-
- 2. Support TBI mode.
-=========================================================================
-VERSION 1.1 <2002/10/4>
-
- The bit4:0 of MII register 4 is called "selector field", and have to be
- 00001b to indicate support of IEEE std 802.3 during NWay process of
- exchanging Link Code Word (FLP).
-
-VERSION 1.2 <2002/11/30>
-
- - Large style cleanup
- - Use ether_crc in stock kernel (linux/crc32.h)
- - Copy mc_filter setup code from 8139cp
- (includes an optimization, and avoids set_bit use)
-
-VERSION 1.6LK <2004/04/14>
-
- - Merge of Realtek's version 1.6
- - Conversion to DMA API
- - Suspend/resume
- - Endianness
- - Misc Rx/Tx bugs
-
-VERSION 2.2LK <2005/01/25>
-
- - RX csum, TX csum/SG, TSO
- - VLAN
- - baby (< 7200) Jumbo frames support
- - Merge of Realtek's version 2.2 (new phy)

- * This is the main module of the Linux GE driver.
- *
- * All source files except skge.c, skdrv1st.h, skdrv2nd.h and sktypes.h
- * are part of SysKonnect's COMMON MODULES for the SK-98xx adapters.
- * Those are used for drivers on multiple OS', so some thing may seem
- * unnecessary complicated on Linux. Please do not try to 'clean up'
- * them without VERY good reasons, because this will make it more
- * difficult to keep the Linux driver in synchronisation with the
- * other versions.
- *
- * Include file hierarchy:

- * Description:
- * After calling this function the descriptor rings and Rx and Tx
- * queues of this port may be reconfigured.
- *
- * It is possible to stop the receive and transmit path separate or
- * both together.
- *
- * Dir = SK_STOP_TX Stops the transmit path only and resets the MAC.
- * The receive queue is still active and
- * the pending Rx frames may be still transferred
- * into the RxD.
- * SK_STOP_RX Stop the receive path. The tansmit path
- * has to be stopped once before.
- * SK_STOP_ALL SK_STOP_TX + SK_STOP_RX
- *
- * RstMode = SK_SOFT_RST Resets the MAC. The PHY is still alive.
- * SK_HARD_RST Resets the MAC and the PHY.
- *
- * Example:
- * 1) A Link Down event was signaled for a port. Therefore the activity
- * of this port should be stopped and a hardware reset should be issued
- * to enable the workaround of XMAC Errata #2. But the received frames
- * should not be discarded.
- * ...

- * (transfer all pending Rx frames)
- * SkGeStopPort(pAC, IoC, Port, SK_STOP_RX, SK_HARD_RST);
- * ...
- *
- * 2) An event was issued which request the driver to switch
- * the 'virtual active' link to an other already active port
- * as soon as possible. The frames in the receive queue of this
- * port may be lost. But the PHY must not be reset during this
- * event.
- * ...
- * SkGeStopPort(pAC, IoC, Port, SK_STOP_ALL, SK_SOFT_RST);
- * ...
- *
- * Extended Description:
- * If SK_STOP_TX is set,
- * o disable the MAC's receive and transmitter to prevent
- * from sending incomplete frames
- * o stop the port's transmit queues before terminating the
- * BMUs to prevent from performing incomplete PCI cycles
- * on the PCI bus
- * - The network Rx and Tx activity and PCI Tx transfer is
- * disabled now.
- * o reset the MAC depending on the RstMode
- * o Stop Interval Timer and Limit Counter of Tx Arbiter,
- * also disable Force Sync bit and Enable Alloc bit.
- * o perform a local reset of the port's Tx path
- * - reset the PCI FIFO of the async Tx queue
- * - reset the PCI FIFO of the sync Tx queue
- * - reset the RAM Buffer async Tx queue
- * - reset the RAM Buffer sync Tx queue
- * - reset the MAC Tx FIFO

- * SK_PNMI_EVT_SEN_XXX The event is generated by the I2C module
- * when a sensor reports a warning or
- * error. The event will store a trap
- * message in the trap buffer.
- * SK_PNMI_EVT_CHG_EST_TIMER The timer event was initiated by this
- * module and is used to calculate the
- * port switches per hour.
- * SK_PNMI_EVT_CLEAR_COUNTER The event clears all counters and
- * timestamps.
- * SK_PNMI_EVT_XMAC_RESET The event is generated by the driver
- * before a hard reset of the XMAC is
- * performed. All counters will be saved
- * and added to the hardware counter
- * values after reset to grant continuous
- * counter values.
- * SK_PNMI_EVT_RLMT_PORT_UP Generated by RLMT to notify that a port
- * went logically up. A trap message will
- * be stored to the trap buffer.
- * SK_PNMI_EVT_RLMT_PORT_DOWN Generated by RLMT to notify that a port
- * went logically down. A trap message will
- * be stored to the trap buffer.
- * SK_PNMI_EVT_RLMT_SEGMENTATION Generated by RLMT to notify that two
- * spanning tree root bridges were
- * detected. A trap message will be stored
- * to the trap buffer.
- * SK_PNMI_EVT_RLMT_ACTIVE_DOWN Notifies PNMI that an active port went
- * down. PNMI will not further add the
- * statistic values to the virtual port.
- * SK_PNMI_EVT_RLMT_ACTIVE_UP Notifies PNMI that a port went up and
- * is now an active port. PNMI will now
- * add the statistic data of this port to
- * the virtual port.
- * SK_PNMI_EVT_RLMT_SET_NETS Notifies PNMI about the net mode. The first parameter
- * contains the number of nets. 1 means single net, 2 means
- * dual net. The second parameter is -1

- *
- * Returns:
- * SK_PNMI_ERR_OK The request was successfully performed.
- * SK_PNMI_ERR_GENERAL A general severe internal error occured.
- * SK_PNMI_ERR_TOO_SHORT The passed buffer is too short to contain
- * the correct data (e.g. a 32bit value is
- * needed, but a 16 bit value was passed).
- * SK_PNMI_ERR_BAD_VALUE The passed value is not in the valid
- * value range.
- * SK_PNMI_ERR_READ_ONLY The OID is read-only and cannot be set.
- * SK_PNMI_ERR_UNKNOWN_INST The requested instance of the OID doesn't

- * Special Interrupt handler
- *
- * The following abstract should show how this module is included
- * in the driver path:
- *
- * In the ISR of the driver the bits for frame transmission complete and
- * for receive complete are checked and handled by the driver itself.
- * The bits of the slow path mask are checked after that and then the
- * entry into the so-called "slow path" is prepared. It is an implementors
- * decision whether this is executed directly or just scheduled by
- * disabling the mask. In the interrupt service routine some events may be
- * generated, so it would be a good idea to call the EventDispatcher
- * right after this ISR.
- *
- * The Interrupt source register of the adapter is NOT read by this module.
- * SO if the drivers implementor needs a while loop around the
- * slow data paths interrupt bits, he needs to call the SkGeSirqIsr() for
- * each loop entered.
- *
- * However, the MAC Interrupt status registers are read in a while loop.

- I2C protocol implementation.
-
- General Description:
-
- The I2C protocol is used for the temperature sensors and for
- the serial EEPROM which hold the configuration.
-
- This file covers functions that allow to read write and do
- some bulk requests a specified I2C address.
-
- The Genesis has 2 I2C buses. One for the EEPROM which holds
- the VPD Data and one for temperature and voltage sensor.
- The following picture shows the I2C buses, I2C devices and
- their control registers.
-
- Note: The VPD functions are in skvpd.c
-.

-. | B2_I2C | | B2_I2C | | B2_I2C |
-. | _CTRL | | _DATA | | _SW |
-. +--------+ +--------+ +----------+
-.
- The I2C bus may be driven by the B2_I2C_SW or by the B2_I2C_CTRL
- and B2_I2C_DATA registers.
- For driver software it is recommended to use the I2C control and
- data register, because I2C bus timing is done by the ASIC and
- an interrupt may be received when the I2C request is completed.
-
- Clock Rate Timing: MIN MAX generated by
- VPD EEPROM: 50 kHz 100 kHz HW
- LM80 over I2C Ctrl/Data reg. 50 kHz 100 kHz HW
- LM80 over B2_I2C_SW register 0 400 kHz SW
-
- Note: The clock generated by the hardware is dependend on the
- PCI clock. If the PCI bus clock is 33 MHz, the I2C/VPD
- clock is 50 kHz.

-IWPRIV COMMAND
-=====================
-
-NAME
- This manual describes the usage of private commands used in Marvell WLAN
- Linux Driver. All the commands available in Wlanconfig will not be available
- in the iwpriv.
-
-SYNOPSIS
- iwpriv <ethX> <command> [sub-command] ...
-
- iwpriv ethX setregioncode <n>
- iwpriv ethX getregioncode
-
-Version 5 Command:
- iwpriv ethX ledgpio <n>
-
-BT Commands:
- The blinding table (BT) contains a list of mac addresses that should be
- ignored by the firmware. It is primarily used for debugging and
- testing networks. It can be edited and inspected with the following
- commands:
-
- iwpriv ethX bt_reset
- iwpriv ethX bt_add <mac_address>
- iwpriv ethX bt_del <mac_address>
- iwpriv ethX bt_list <id>
-
-FWT Commands:
- The forwarding table (FWT) is a feature used to manage mesh network
- routing in the firmware. The FWT is essentially a routing table that
- associates a destination mac address (da) with a next hop receiver
- address (ra). The FWT can be inspected and edited with the following
- iwpriv commands, which are described in greater detail below.
- Eventually, the table will be automatically maintained by a custom
- routing protocol.
-
- NOTE: FWT commands replace the previous DFT commands. What were the DFT
- commands?, you might ask. They were an earlier API to the firmware that
- implemented a simple MAC-layer forwarding mechanism. In the unlikely
- event that you were using these commands, you must migrate to the new
- FWT commands which can be used to achieve the same functionality.
-
- iwpriv ethX fwt_add [parameters]
- iwpriv ethX fwt_del [parameters]
- iwpriv ethX fwt_lookup [parameters]
- iwpriv ethX fwt_list [parameters]
- iwpriv ethX fwt_list_route [parameters]
- iwpriv ethX fwt_list_neigh [parameters]
- iwpriv ethX fwt_reset [parameters]
- iwpriv ethX fwt_cleanup
- iwpriv ethX fwt_time
-
-MESH Commands:
-
- The MESH commands are used to configure various features of the mesh
- routing protocol. The following commands are supported:
-
- iwpriv ethX mesh_get_ttl
- iwpriv ethX mesh_set_ttl ttl
-
-DESCRIPTION
- Those commands are used to send additional commands to the Marvell WLAN
- card via the Linux device driver.
-
- The ethX parameter specifies the network device that is to be used to
- perform this command on. it could be eth0, eth1 etc.
-
-setregioncode
- This command is used to set the region code in the station.
- where value is 'region code' for various regions like
- USA FCC, Canada IC, Spain, France, Europe ETSI, Japan ...
-
- Usage:
- iwpriv ethX setregioncode 0x10: set region code to USA (0x10).
-
-getregioncode
- This command is used to get the region code information set in the
- station.
-
-ledgpio
- This command is used to set/get LEDs.
-
- iwpriv ethX ledgpio <LEDs>
- will set the corresponding LED for the GPIO Line.
-
- iwpriv ethX ledgpio
- will give u which LEDs are Enabled.
-
- Usage:
- iwpriv eth1 ledgpio 1 0 2 1 3 4
- will enable
- LED 1 -> GPIO 0
- LED 2 -> GPIO 1
- LED 3 -> GPIO 4
-
- iwpriv eth1 ledgpio
- shows LED information in the format as mentioned above.
-
- Note: LED0 is invalid
- Note: Maximum Number of LEDs are 16.
-
-fwt_add
- This command is used to insert an entry into the FWT table. The list of
- parameters must follow the following structure:
-
- iwpriv ethX fwt_add da ra [metric dir ssn dsn hopcount ttl expiration sleepmode snr]
-
- The parameters between brackets are optional, but they must appear in
- the order specified. For example, if you want to specify the metric,
- you must also specify the dir, ssn, and dsn but you need not specify the
- hopcount, expiration, sleepmode, or snr. Any unspecified parameters
- will be assigned the defaults specified below.
-
- The different parameters are:-
- da -- DA MAC address in the form 00:11:22:33:44:55
- ra -- RA MAC address in the form 00:11:22:33:44:55
- metric -- route metric (cost: smaller-metric routes are
- preferred, default is 0)
- dir -- direction (1 for direct, 0 for reverse,
- default is 1)
- ssn -- Source Sequence Number (time at the RA for
- reverse routes. Default is 0)
- dsn -- Destination Sequence Number (time at the DA
- for direct routes. Default is 0)
- hopcount -- hop count (currently unused, default is 0)
- ttl -- TTL (Only used in reverse entries)
- expiration -- entry expiration (in ticks, where a tick is
- 1024us, or ~ 1ms. Use 0 for an indefinite
- entry, default is 0)
- sleepmode -- RA's sleep mode (currently unused, default is
- 0)
- snr -- SNR in the link to RA (currently unused,
- default is 0)
-
- The command does not return anything.
-
-fwt_del
- This command is used to remove an entry to the FWT table. The list of
- parameters must follow the following structure:
-
- iwpriv ethX fwt_del da ra [dir]
-
- where the different parameters are:-
- da -- DA MAC address (in the form "00:11:22:33:44:55")
- ra -- RA MAC address (in the form "00:11:22:33:44:55")
- dir -- direction (1 for direct, 0 for reverse,
- default is 1)
-
- The command does not return anything.
-
-fwt_lookup
- This command is used to get the best route in the FWT table to a given
- host. The only parameter is the MAC address of the host that is being
- looked for.
-
- iwpriv ethX fwt_lookup da
-
- where:-
- da -- DA MAC address (in the form "00:11:22:33:44:55")
-
- The command returns an output string identical to the one returned by
- fwt_list described below.
-
-
-fwt_list
- This command is used to list a route from the FWT table. The only
- parameter is the index into the table. If you want to list all the
- routes in a table, start with index=0, and keep listing until you get a
- "(null)" string. Note that the indicies may change as the fwt is
- updated. It is expected that most users will not use fwt_list directly,
- but that a utility similar to the traditional route command will be used
- to invoke fwt_list over and over.
-
- iwpriv ethX fwt_list index
-
- The output is a string of the following form:
-
- da ra metric dir ssn dsn hopcount ttl expiration sleepmode snr
-
- where the different fields are:-
- da -- DA MAC address (in the form "00:11:22:33:44:55")
- ra -- RA MAC address (in the form "00:11:22:33:44:55")
- metric -- route metric (cost: smaller-metric routes are preferred)
- dir -- direction (1 for direct, 0 for reverse)
- ssn -- Source Sequence Number (time at the RA for reverse routes)
- dsn -- Destination Sequence Number (time at the DA for direct routes)
- hopcount -- hop count (currently unused)
- ttl -- TTL (only used in reverse entries)
- expiration -- entry expiration (in ticks, where a tick is 1024us, or ~ 1ms. Use 0 for an indefinite entry)
- sleepmode -- RA's sleep mode (currently unused)
- snr -- SNR in the link to RA (currently unused)
-
-fwt_list_route
- This command is used to list a route from the FWT table. The only
- parameter is the route ID. If you want to list all the routes in a
- table, start with rid=0, and keep incrementing rid until you get a
- "(null)" string. This function is similar to fwt_list. The only
- difference is the output format. Also note that this command is meant
- for debugging. It is expected that users will use fwt_lookup and
- fwt_list. One important reason for this is that the route id may change
- as the route table is altered.
-
- iwpriv ethX fwt_list_route rid
-
- The output is a string of the following form:
-
- da metric dir nid ssn dsn hopcount ttl expiration
-
- where the different fields are:-
- da -- DA MAC address (in the form "00:11:22:33:44:55")
- metric -- route metric (cost: smaller-metric routes are preferred)
- dir -- direction (1 for direct, 0 for reverse)
- nid -- Next-hop (neighbor) host ID (nid)
- ssn -- Source Sequence Number (time at the RA for reverse routes)
- dsn -- Destination Sequence Number (time at the DA for direct routes)
- hopcount -- hop count (currently unused)
- ttl -- TTL count (only used in reverse entries)
- expiration -- entry expiration (in ticks, where a tick is 1024us, or ~ 1ms. Use 0 for an indefinite entry)
-
-fwt_list_neigh
- This command is used to list a neighbor from the FWT table. The only
- parameter is the neighbor ID. If you want to list all the neighbors in a
- table, start with nid=0, and keep incrementing nid until you get a
- "(null)" string. Note that the nid from a fwt_list_route command can be
- used as an input to this command. Also note that this command is meant
- mostly for debugging. It is expected that users will use fwt_lookup.
- One important reason for this is that the neighbor id may change as the
- neighbor table is altered.
-
- iwpriv ethX fwt_list_neigh nid
-
- The output is a string of the following form:
-
- ra sleepmode snr references
-
- where the different fields are:-
- ra -- RA MAC address (in the form "00:11:22:33:44:55")
- sleepmode -- RA's sleep mode (currently unused)
- snr -- SNR in the link to RA (currently unused)
- references -- RA's reference counter
-
-fwt_reset
- This command is used to reset the FWT table, getting rid of all the
- entries. There are no input parameters.
-
- iwpriv ethX fwt_reset
-
- The command does not return anything.
-
-fwt_cleanup
- This command is used to perform user-based garbage recollection. The
- FWT table is checked, and all the entries that are expired or invalid
- are cleaned. Note that this is exported to the driver for debugging
- purposes, as garbage collection is also fired by the firmware when in
- space problems. There are no input parameters.
-
- iwpriv ethX fwt_cleanup
-
- The command does returns the number of invalid/expired routes deleted.
-
-fwt_time
- This command returns a card's internal time representation. It is this
- time that is used to represent the expiration times of FWT entries. The
- number is not consistent from card to card; it is simply a timer count.
- The fwt_time command is used to inspect the timer so that expiration
- times reported by fwt_list can be properly interpreted.
-
- iwpriv ethX fwt_time
-
-mesh_get_ttl
-
- The mesh ttl is the number of hops a mesh packet can traverse before it
- is dropped. This parameter is used to prevent infinite loops in the
- mesh network. The value returned by this function is the ttl assigned
- to all mesh packets. Currently there is no way to control the ttl on a
- per packet or per socket basis.
-
- iwpriv ethX mesh_get_ttl
-
-mesh_set_ttl ttl
-
- Set the ttl. The argument must be between 0 and 255.
-
- iwpriv ethX mesh_set_ttl <ttl>

+
+ Fourth revision: This message format supports the USA28XG
+
+ Buffer formats for RX/TX data messages are not defined by
+ a structure, but are described here:
+
+ USB OUT (host -> USAxx, transmit) messages contain a
+ REQUEST_ACK indicator (set to 0xff to request an ACK at the
+ completion of transmit; 0x00 otherwise), followed by data:
+
+ RQSTACK DAT DAT DAT ...
+
+ with a total data length of up to 63.
+
+ USB IN (USAxx -> host, receive) messages begin with a status
+ byte in which the 0x80 bit is either:
+
+ (a) 0x80 bit clear
+ indicates that the bytes following it are all data
+ bytes:
+
+ STAT DATA DATA DATA DATA DATA ...
+
+ for a total of up to 63 DATA bytes,
+
+ or:
+
+ (b) 0x80 bit set
+ indiates that the bytes following alternate data and
+ status bytes:
+
+ STAT DATA STAT DATA STAT DATA STAT DATA ...
+
+ for a total of up to 32 DATA bytes.
+
+ The valid bits in the STAT bytes are:
+
+ OVERRUN 0x02
+ PARITY 0x04
+ FRAMING 0x08
+ BREAK 0x10
+
+ Notes:
+
+ (1) The OVERRUN bit can appear in either (a) or (b) format
+ messages, but the but the PARITY/FRAMING/BREAK bits
+ only appear in (b) format messages.
+ (2) For the host to determine the exact point at which the
+ overrun occurred (to identify the point in the data
+ stream at which the data was lost), it needs to count
+ 128 characters, starting at the first character of the
+ message in which OVERRUN was reported; the lost character(s)
+ would have been received between the 128th and 129th
+ characters.
+ (3) An RX data message in which the first byte has 0x80 clear
+ serves as a "break off" indicator.
+
+ revision history:
+
+ 1999feb10 add reportHskiaChanges to allow us to ignore them
+ 1999feb10 add txAckThreshold for fast+loose throughput enhancement
+ 1999mar30 beef up support for RX error reporting
+ 1999apr14 add resetDataToggle to control message
+ 2000jan04 merge with usa17msg.h
+ 2000jun01 add extended BSD-style copyright text
+ 2001jul05 change message format to improve OVERRUN case
+ 2002jun05 update copyright date, improve comments
+ 2006feb06 modify for FX1 chip

+ * Almost all knowlegde used while writing this driver was gathered by:
+ * - analyzing traffic between device and the M$ Windows 2000 driver,
+ * - trying different bit combinations and checking pin states
+ * with a voltmeter,
+ * - receiving malformed frames and producing buffer overflows
+ * to learn how errors are reported,
+ * So, THIS CODE CAN DESTROY OTi-6858 AND ANY OTHER DEVICES, THAT ARE

+ *
+ * TODO:
+ * - implement correct flushing for ioctls and oti6858_close()
+ * - check how errors (rx overflow, parity error, framing error) are reported
+ * - implement oti6858_break_ctl()
+ * - implement more ioctls
+ * - test/implement flow control

+ * all our journaled data buffers for journaled files (e.g. files in the
+ * meta_fs like rindex, or files for which chattr +j was done.)

+ * We can have metadata bufs and jdata bufs in the same journal. So each
+ * type gets its own log header, for which we need to reserve a block.
+ * In fact, each type has the potential for needing more than one header
+ * in cases where we have more buffers than will fit on a journal page.
+ * Metadata journal entries take up half the space of journaled buffer entries.
+ * Thus, metadata entries have buf_limit (502) and journaled buffers have
+ * databuf_limit (251) before they cause a wrap around.

+ * Allocation group filestream associations are tracked with per-ag atomic
+ * counters. These counters allow _xfs_filestream_pick_ag() to tell whether a
+ * particular AG already has active filestreams associated with it. The mount
+ * point's m_peraglock is used to protect these counters from per-ag array
+ * re-allocation during a growfs operation. When xfs_growfs_data_private() is
+ * about to reallocate the array, it calls xfs_filestream_flush() with the
+ * m_peraglock held in write mode.
+ *
+ * Since xfs_mru_cache_flush() guarantees that all the free functions for all
+ * the cache elements have finished executing before it returns, it's safe for
+ * the free functions to use the atomic counters without m_peraglock protection.
+ * This allows the implementation of xfs_fstrm_free_func() to be agnostic about
+ * whether it was called with the m_peraglock held in read mode, write mode or
+ * not held at all. The race condition this addresses is the following:
+ *
+ * - The work queue scheduler fires and pulls a filestream directory cache
+ * element off the LRU end of the cache for deletion, then gets pre-empted.
+ * - A growfs operation grabs the m_peraglock in write mode, flushes all the
+ * remaining items from the cache and reallocates the mount point's per-ag
+ * array, resetting all the counters to zero.
+ * - The work queue thread resumes and calls the free function for the element
+ * it started cleaning up earlier. In the process it decrements the
+ * filestreams counter for an AG that now has no references.
+ *
+ * With a shrinkfs feature, the above scenario could panic the system.
+ *
+ * All other uses of the following macros should be protected by either the
+ * m_peraglock held in read mode, or the cache's internal locking exposed by the
+ * interval between a call to xfs_mru_cache_lookup() and a call to
+ * xfs_mru_cache_done(). In addition, the m_peraglock must be held in read mode
+ * when new elements are added to the cache.
+ *
+ * Combined, these locking rules ensure that no associations will ever exist in
+ * the cache that reference per-ag array elements that have since been
+ * reallocated.

+/*
+ * The MRU Cache data structure consists of a data store, an array of lists and
+ * a lock to protect its internal state. At initialisation time, the client
+ * supplies an element lifetime in milliseconds and a group count, as well as a
+ * function pointer to call when deleting elements. A data structure for
+ * queueing up work in the form of timed callbacks is also included.
+ *
+ * The group count controls how many lists are created, and thereby how finely
+ * the elements are grouped in time. When reaping occurs, all the elements in
+ * all the lists whose time has expired are deleted.
+ *
+ * To give an example of how this works in practice, consider a client that
+ * initialises an MRU Cache with a lifetime of ten seconds and a group count of
+ * five. Five internal lists will be created, each representing a two second
+ * period in time. When the first element is added, time zero for the data
+ * structure is initialised to the current time.
+ *
+ * All the elements added in the first two seconds are appended to the first
+ * list. Elements added in the third second go into the second list, and so on.
+ * If an element is accessed at any point, it is removed from its list and
+ * inserted at the head of the current most-recently-used list.
+ *
+ * The reaper function will have nothing to do until at least twelve seconds
+ * have elapsed since the first element was added. The reason for this is that
+ * if it were called at t=11s, there could be elements in the first list that
+ * have only been inactive for nine seconds, so it still does nothing. If it is
+ * called anywhere between t=12 and t=14 seconds, it will delete all the
+ * elements that remain in the first list. It's therefore possible for elements
+ * to remain in the data store even after they've been inactive for up to
+ * (t + t/g) seconds, where t is the inactive element lifetime and g is the
+ * number of groups.
+ *
+ * The above example assumes that the reaper function gets called at least once
+ * every (t/g) seconds. If it is called less frequently, unused elements will
+ * accumulate in the reap list until the reaper function is eventually called.
+ * The current implementation uses work queue callbacks to carefully time the
+ * reaper function calls, so this should happen rarely, if at all.
+ *
+ * From a design perspective, the primary reason for the choice of a list array
+ * representing discrete time intervals is that it's only practical to reap
+ * expired elements in groups of some appreciable size. This automatically
+ * introduces a granularity to element lifetimes, so there's no point storing an
+ * individual timeout with each element that specifies a more precise reap time.
+ * The bonus is a saving of sizeof(long) bytes of memory per element stored.
+ *
+ * The elements could have been stored in just one list, but an array of
+ * counters or pointers would need to be maintained to allow them to be divided
+ * up into discrete time groups. More critically, the process of touching or
+ * removing an element would involve walking large portions of the entire list,
+ * which would have a detrimental effect on performance. The additional memory
+ * requirement for the array of list heads is minimal.
+ *
+ * When an element is touched or deleted, it needs to be removed from its
+ * current list. Doubly linked lists are used to make the list maintenance
+ * portion of these operations O(1). Since reaper timing can be imprecise,
+ * inserts and lookups can occur when there are no free lists available. When
+ * this happens, all the elements on the LRU list need to be migrated to the end
+ * of the reap list. To keep the list maintenance portion of these operations
+ * O(1) also, list tails need to be accessible without walking the entire list.
+ * This is the reason why doubly linked list heads are used.
+ */
+
+/*
+ * An MRU Cache is a dynamic data structure that stores its elements in a way
+ * that allows efficient lookups, but also groups them into discrete time
+ * intervals based on insertion time. This allows elements to be efficiently
+ * and automatically reaped after a fixed period of inactivity.
+ *
+ * When a client data pointer is stored in the MRU Cache it needs to be added to
+ * both the data store and to one of the lists. It must also be possible to
+ * access each of these entries via the other, i.e. to:
+ *
+ * a) Walk a list, removing the corresponding data store entry for each item.
+ * b) Look up a data store entry, then access its list entry directly.
+ *
+ * To achieve both of these goals, each entry must contain both a list entry and
+ * a key, in addition to the user's data pointer. Note that it's not a good
+ * idea to have the client embed one of these structures at the top of their own
+ * data structure, because inserting the same item more than once would most
+ * likely result in a loop in one of the lists. That's a sure-fire recipe for
+ * an infinite loop in the code.

+ * SMP/VPE-safe functions to access "registers" (see note).
+ *
+ * NOTES:
+* - These macros use ll/sc instructions, so it is your responsibility to
+ * ensure these are available on your platform before including this file.
+ * - The MIPS32 spec states that ll/sc results are undefined for uncached
+ * accesses. This means they can't be used on HW registers accessed
+ * through kseg1. Code which requires these macros for this purpose must
+ * front-end the registers with cached memory "registers" and have a single
+ * thread update the actual HW registers.
+ * - A maximum of 2k of code can be inserted between ll and sc. Every
+ * memory accesses between the instructions will increase the chance of
+ * sc failing and having to loop.
+ * - When using custom_read_reg32/custom_write_reg32 only perform the
+ * necessary logical operations on the register value in between these
+ * two calls. All other logic should be performed before the first call.
+ * - There is a bug on the R10000 chips which has a workaround. If you
+ * are affected by this bug, make sure to define the symbol 'R10000_LLSC_WAR'
+ * to be non-zero. If you are using this header from within linux, you may
+ * include <asm/war.h> before including this file to have this defined
+ * appropriately for you.

+ * 2) The block copy engine register are divided into two regions, one
+ * for the control/configuration of the engine proper and one for the
+ * values of the descriptors used in the copy process. These have
+ * different base defines (CTRL_BASE vs DESC_BASE)
+ * 3) These constants are for physical addresses which means that they
+ * work correctly with "ioremap" and friends. This means that device
+ * drivers will need to remap these addresses using ioremap and perhaps
+ * the readw/writew macros. Or they could use the regptr() macro
+ * defined below, but the readw/writew calls are the correct thing.
+ * 4) The UARTs have an additional status register offset from the base
+ * address. This register isn't used in the standard 8250 driver but
+ * may be used in other software. Consult the hardware datasheet for
+ * offset details.
+ * 5) For some unknown reason the security engine (MSP_SEC_BASE) registers
+ * start at an offset of 0x84 from the base address but the block of
+ * registers before this is reserved for the security engine. The
+ * driver will have to be aware of this but it makes the register

+ * the check without damaging the parity block, in these cases the parity
+ * block is re-marked up to date (assuming the check was successful) and is
+ * not re-read from disk.
+ * 2/ When a write operation is requested we immediately lock the affected
+ * blocks, and mark them as not up to date. This causes new read requests
+ * to be held off, as well as parity checks and compute block operations.

+ * @max_length: total length we can parse into (eg, whole packet length)
+ *
+ * Returns: 0 or a negative error code if there is a problem.

+ * This function initializes an opaque iterator struct which can then
+ * be passed to ieee80211_radiotap_iterator_next() to visit every radiotap
+ * argument which is present in the header. It knows about extended
+ * present headers and handles them.
+ *
+ * How to use:
+ * call __ieee80211_radiotap_iterator_init() to init a semi-opaque iterator
+ * struct ieee80211_radiotap_iterator (no need to init the struct beforehand)
+ * checking for a good 0 return code. Then loop calling
+ * __ieee80211_radiotap_iterator_next()... it returns either 0,
+ * -ENOENT if there are no more args to parse, or -EINVAL if there is a problem.
+ * The iterator's @this_arg member points to the start of the argument
+ * associated with the current argument index that is present, which can be
+ * found in the iterator's @this_arg_index member. This arg index corresponds
+ * to the IEEE80211_RADIOTAP_... defines.
+ *
+ * Radiotap header length:
+ * You can find the CPU-endian total radiotap header length in
+ * iterator->max_length after executing ieee80211_radiotap_iterator_init()
+ * successfully.
+ *
+ * Alignment Gotcha:
+ * You must take care when dereferencing iterator.this_arg
+ * for multibyte types... the pointer is not aligned. Use
+ * get_unaligned((type *)iterator.this_arg) to dereference
+ * iterator.this_arg for type "type" safely on all arches.
