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.

+ A Simple Guide to Configure KGDB
+
+ Sonic Zhang <sonic.zhang@analog.com>
+ Aug. 24th 2006
+
+
+This KGDB patch enables the kernel developer to do source level debugging on
+the kernel for the Blackfin architecture. The debugging works over either the
+ethernet interface or one of the uarts. Both software breakpoints and
+hardware breakpoints are supported in this version.
+http://docs.blackfin.uclinux.org/doku.php?id=kgdb
+
+
+2 known issues:
+1. This bug:
+ 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.

+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.

-
-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

+ 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:
+drop, truncate, or pass up oversize packets, but dropping oversize
+packets is preferred.

+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.

-#
-# 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>
- *
- * New A20 code ported from SYSLINUX by H. Peter Anvin. AMD Elan bugfixes
- * by Robert Schwebel, December 2001 <robert@schwebel.de>

- * some changes and additional features by Christoph Niemann,
- * March 1993/June 1994 (Christoph.Niemann@linux.org)

- *
- * Transcribed from Intel (as86) -> AT&T (gas) by Chris Noe, May 1999.

- *
- * 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>

- * Added long mode checking and SSE force. March 2003, Andi Kleen.

+ * The DS1682 elapsed timer recorder is a simple device that implements
+ * one elapsed time counter, one event counter, an alarm signal and 10
+ * 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 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.

+
+ If you say Y here and enable the "power/persist" attribute
+ for a USB device, the device's data structures will remain
+ persistent across system suspend, even if the USB bus loses
+ power. (This includes hibernation, also known as swsusp or
+ suspend-to-disk.) The devices will reappear as if by magic
+ when the system wakes up, with no need to unmount USB
+ filesystems, rmmod host-controller drivers, or do anything
+ else.
+
+ WARNING: This option can be dangerous!
+
+ If a USB device is replaced by another of the same type while
+ the system is asleep, there's a good chance the kernel won't
+ detect the change. Likewise if the media in a USB storage
+ device is replaced. When this happens it's almost certain to
+ cause data corruption and maybe even crash your system.

+ (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.
