+What: /dev/fw[0-9]+
+Date: May 2007
+KernelVersion: 2.6.22
+Contact: linux1394-devel@lists.sourceforge.net
+Description:
+ The character device files /dev/fw* are the interface between
+ firewire-core and IEEE 1394 device drivers implemented in
+ userspace. The ioctl(2)- and read(2)-based ABI is defined and
+ documented in <linux/firewire-cdev.h>.
+
+ This ABI offers most of the features which firewire-core also
+ exposes to kernelspace IEEE 1394 drivers.
+
+ Each /dev/fw* is associated with one IEEE 1394 node, which can
+ be remote or local nodes. Operations on a /dev/fw* file have
+ different scope:
+ - The 1394 node which is associated with the file:
+ - Asynchronous request transmission
+ - Get the Configuration ROM
+ - Query node ID
+ - Query maximum speed of the path between this node
+ and local node
+ - The 1394 bus (i.e. "card") to which the node is attached to:
+ - Isochronous stream transmission and reception
+ - Asynchronous stream transmission and reception
+ - Asynchronous broadcast request transmission
+ - PHY packet transmission and reception
+ - Allocate, reallocate, deallocate isochronous
+ resources (channels, bandwidth) at the bus's IRM
+ - Query node IDs of local node, root node, IRM, bus
+ manager
+ - Query cycle time
+ - Bus reset initiation, bus reset event reception
+ - All 1394 buses:
+ - Allocation of IEEE 1212 address ranges on the local
+ link layers, reception of inbound requests to such
+ an address range, asynchronous response transmission
+ to inbound requests
+ - Addition of descriptors or directories to the local
+ nodes' Configuration ROM
+
+ Due to the different scope of operations and in order to let
+ userland implement different access permission models, some
+ operations are restricted to /dev/fw* files that are associated
+ with a local node:
+ - Addition of descriptors or directories to the local
+ nodes' Configuration ROM
+ - PHY packet transmission and reception
+
+ A /dev/fw* file remains associated with one particular node
+ during its entire life time. Bus topology changes, and hence
+ node ID changes, are tracked by firewire-core. ABI users do not
+ need to be aware of topology.
+
+ The following file operations are supported:
+
+ open(2)
+ Currently the only useful flags are O_RDWR.
+
+ ioctl(2)
+ Initiate various actions. Some take immediate effect, others
+ are performed asynchronously while or after the ioctl returns.
+ See the inline documentation in <linux/firewire-cdev.h> for
+ descriptions of all ioctls.
+
+ poll(2), select(2), epoll_wait(2) etc.
+ Watch for events to become available to be read.
+
+ read(2)
+ Receive various events. There are solicited events like
+ outbound asynchronous transaction completion or isochronous
+ buffer completion, and unsolicited events such as bus resets,
+ request reception, or PHY packet reception. Always use a read
+ buffer which is large enough to receive the largest event that
+ could ever arrive. See <linux/firewire-cdev.h> for descriptions
+ of all event types and for which ioctls affect reception of
+ events.
+
+ mmap(2)
+ Allocate a DMA buffer for isochronous reception or transmission
+ and map it into the process address space. The arguments should
+ be used as follows: addr = NULL, length = the desired buffer
+ size, i.e. number of packets times size of largest packet,
+ prot = at least PROT_READ for reception and at least PROT_WRITE
+ for transmission, flags = MAP_SHARED, fd = the handle to the
+ /dev/fw*, offset = 0.
+
+ Isochronous reception works in packet-per-buffer fashion except
+ for multichannel reception which works in buffer-fill mode.
+
+ munmap(2)
+ Unmap the isochronous I/O buffer from the process address space.
+
+ close(2)
+ Besides stopping and freeing I/O contexts that were associated
+ with the file descriptor, back out any changes to the local
+ nodes' Configuration ROM. Deallocate isochronous channels and
+ bandwidth at the IRM that were marked for kernel-assisted
+ re- and deallocation.

+Description:
+ The sysfs iov directory is used to manage and examine the port
+ P_Key and guid paravirtualization. This directory is added only
+ for the master -- slaves do not have it.
+
+ Under iov/ports, the administrator may examine the gid and P_Key
+ tables as they are present in the device (and as are seen in the
+ "network view" presented to the SM).
+
+ The "pkeys" and "gids" subdirectories contain one file for each
+ entry in the port's P_Key or GID table respectively. For
+ example, ports/1/pkeys/10 contains the value at index 10 in port
+ 1's P_Key table.

+ <m>/pkey_idx/<n>: (RW) Writable except for RoCE pkeys.
+ m = 1..2, n = 0..126
+
+ Under the iov/<pci slot number>
+ directories, the admin may map the index
+ numbers in the physical tables (as under
+ iov/ports) to the paravirtualized index
+ numbers that guests see.
+
+ For example, if the administrator, for
+ port 1 on guest 2 maps physical pkey
+ index 10 to virtual index 1, then that
+ guest, whenever it uses its pkey index
+ 1, will actually be using the real pkey
+ index 10.

+Contact: tpmdd-devel@lists.sf.net
+Description: The "durations" property shows the 3 vendor-specific values

+ any longer than necessary before starting to poll for a

+
+ Here the short, medium and long durations are displayed in
+ usecs. "[original]" indicates that the values are displayed
+ unmodified from when they were queried from the chip.
+ Durations can be modified in the case where a buggy chip
+ reports them in msec instead of usec and they need to be

+Date: January 2, 2006
+KernelVersion: 2.6.15
+Contact: linux-rdma@vger.kernel.org
+Description: Interface for making ib_srp connect to a new target.
+ One can request ib_srp to connect to a new target by writing
+ a comma-separated list of login parameters to this sysfs
+ attribute. The supported parameters are:
+ * id_ext, a 16-digit hexadecimal number specifying the eight
+ byte identifier extension in the 16-byte SRP target port
+ identifier. The target port identifier is sent by ib_srp
+ to the target in the SRP_LOGIN_REQ request.
+ * ioc_guid, a 16-digit hexadecimal number specifying the eight
+ byte I/O controller GUID portion of the 16-byte target port
+ identifier.
+ * dgid, a 32-digit hexadecimal number specifying the
+ destination GID.
+ * pkey, a four-digit hexadecimal number specifying the
+ InfiniBand partition key.
+ * service_id, a 16-digit hexadecimal number specifying the
+ InfiniBand service ID used to establish communication with
+ the SRP target. How to find out the value of the service ID
+ is specified in the documentation of the SRP target.
+ * max_sect, a decimal number specifying the maximum number of
+ 512-byte sectors to be transferred via a single SCSI command.
+ * max_cmd_per_lun, a decimal number specifying the maximum
+ number of outstanding commands for a single LUN.
+ * io_class, a hexadecimal number specifying the SRP I/O class.
+ Must be either 0xff00 (rev 10) or 0x0100 (rev 16a). The I/O
+ class defines the format of the SRP initiator and target
+ port identifiers.
+ * initiator_ext, a 16-digit hexadecimal number specifying the
+ identifier extension portion of the SRP initiator port
+ identifier. This data is sent by the initiator to the target
+ in the SRP_LOGIN_REQ request.
+ * cmd_sg_entries, a number in the range 1..255 that specifies
+ the maximum number of data buffer descriptors stored in the
+ SRP_CMD information unit itself. With allow_ext_sg=0 the
+ parameter cmd_sg_entries defines the maximum S/G list length
+ for a single SRP_CMD, and commands whose S/G list length
+ exceeds this limit after S/G list collapsing will fail.
+ * allow_ext_sg, whether ib_srp is allowed to include a partial
+ memory descriptor list in an SRP_CMD instead of the entire
+ list. If a partial memory descriptor list has been included
+ in an SRP_CMD the remaining memory descriptors are
+ communicated from initiator to target via an additional RDMA
+ transfer. Setting allow_ext_sg to 1 increases the maximum
+ amount of data that can be transferred between initiator and
+ target via a single SCSI command. Since not all SRP target
+ implementations support partial memory descriptor lists the
+ default value for this option is 0.
+ * sg_tablesize, a number in the range 1..2048 specifying the
+ maximum S/G list length the SCSI layer is allowed to pass to
+ ib_srp. Specifying a value that exceeds cmd_sg_entries is
+ only safe with partial memory descriptor list support enabled
+ (allow_ext_sg=1).
+ * comp_vector, a number in the range 0..n-1 specifying the
+ MSI-X completion vector of the first RDMA channel. Some
+ HCA's allocate multiple (n) MSI-X vectors per HCA port. If
+ the IRQ affinity masks of these interrupts have been
+ configured such that each MSI-X interrupt is handled by a
+ different CPU then the comp_vector parameter can be used to
+ spread the SRP completion workload over multiple CPU's.
+ * tl_retry_count, a number in the range 2..7 specifying the
+ IB RC retry count.
+ * queue_size, the maximum number of commands that the
+ initiator is allowed to queue per SCSI host. The default
+ value for this parameter is 62. The lowest supported value
+ is 2.

+ 0xXX-0xYYYY: A directory for dump of type 0xXX and
+ id 0xYYYY (in hex). The name of this
+ directory should not be relied upon to

+ among all dumps. For determining the type
+ and ID of the dump, use the id and type files.
+ Do not rely on any particular size of dump
+ type or dump id.
+
+ Each dump has the following files:
+ id: An ASCII representation of the dump ID
+ in hex (e.g. '0x01')
+ type: An ASCII representation of the type of
+ dump in the format "0x%x %s" with the ID
+ in hex and a description of the dump type
+ (or 'unknown').
+ Type '0xffffffff unknown' is used when
+ we could not get the type from firmware.
+ e.g. '0x02 System/Platform Dump'
+ dump: A binary file containing the dump.
+ The size of the dump is the size of this file.
+ acknowledge: When 'ack' is written to this, we will
+ acknowledge that we've retrieved the
+ dump to the service processor. It will
+ then remove it, making the dump
+ inaccessible.
+ Reading this file will get a list of
+ supported actions.

+Date: Feb 2014
+Contact: Stewart Smith <stewart@linux.vnet.ibm.com>
+Description:
+ This directory exposes error log entries retrieved
+ through the OPAL firmware interface.
+
+ Each error log is identified by a unique ID and will
+ exist until explicitly acknowledged to firmware.
+
+ Each log entry has a directory in /sys/firmware/opal/elog.
+
+ Log entries may be purged by the service processor
+ before retrieved by firmware or retrieved/acknowledged by
+ Linux if there is no room for more log entries.
+
+ In the event that Linux has retrieved the log entries
+ but not explicitly acknowledged them to firmware and
+ the service processor needs more room for log entries,
+ the only remaining copy of a log message may be in
+ Linux.
+
+ Typically, a user space daemon will monitor for new
+ entries, read them out and acknowledge them.
+
+ The service processor may be able to store more log
+ entries than firmware can, so after you acknowledge
+ an event from Linux you may instantly get another one
+ from the queue that was generated some time in the past.
+
+ The raw log format is a binary format. We currently
+ do not parse this at all in kernel, leaving it up to
+ user space to solve the problem. In future, we may
+ do more parsing in kernel and add more files to make
+ it easier for simple user space processes to extract
+ more information.
+
+ For each log entry (directory), there are the following
+ files:
+
+ id: An ASCII representation of the ID of the
+ error log, in hex - e.g. "0x01".
+
+ type: An ASCII representation of the type id and
+ description of the type of error log.
+ Currently just "0x00 PEL" - platform error log.
+ In the future there may be additional types.
+
+ raw: A read-only binary file that can be read
+ to get the raw log entry. These are
+ <16kb, often just hundreds of bytes and
+ "average" 2kb.
+
+ acknowledge: Writing 'ack' to this file will acknowledge
+ the error log to firmware (and in turn
+ the service processor, if applicable).
+ Shortly after acknowledging it, the log
+ entry will be removed from sysfs.
+ Reading this file will list the supported
+ operations (currently just acknowledge).

+On some architectures, when the kernel loads any userspace program it
+maps an ELF DSO into that program's address space. This DSO is called
+the vDSO and it often contains useful and highly-optimized alternatives
+to real syscalls.
+
+These functions are called just like ordinary C function according to
+your platform's ABI. Call them from a sensible context. (For example,
+if you set CS on x86 to something strange, the vDSO functions are
+within their rights to crash.) In addition, if you pass a bad
+pointer to a vDSO function, you might get SIGSEGV instead of -EFAULT.
+
+To find the DSO, parse the auxiliary vector passed to the program's
+entry point. The AT_SYSINFO_EHDR entry will point to the vDSO.
+
+The vDSO uses symbol versioning; whenever you request a symbol from the
+vDSO, specify the version you are expecting.
+
+Programs that dynamically link to glibc will use the vDSO automatically.
+Otherwise, you can use the reference parser in
+tools/testing/selftests/vDSO/parse_vdso.c.
+
+Unless otherwise noted, the set of symbols with any given version and the
+ABI of those symbols is considered stable. It may vary across architectures,
+though.
+
+(As of this writing, this ABI documentation as been confirmed for x86_64.
+ The maintainers of the other vDSO-using architectures should confirm
+ that it is correct for their architecture.)
