+----------------------------------------
+
+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+This directory attempts to document the ABI between the Linux kernel and
+userspace, and the relative stability of these interfaces. Due to the
+everchanging nature of Linux, and the differing maturity levels, these
+interfaces should be used by userspace programs in different ways.
+
+We have four different levels of ABI stability, as shown by the four
+different subdirectories in this location. Interfaces may change levels
+of stability according to the rules described below.
+
+The different levels of stability are:
+
+ stable/
+ This directory documents the interfaces that the developer has
+ defined to be stable. Userspace programs are free to use these
+ interfaces with no restrictions, and backward compatibility for
+ them will be guaranteed for at least 2 years. Most interfaces
+ (like syscalls) are expected to never change and always be
+ available.
+
+ testing/
+ This directory documents interfaces that are felt to be stable,
+ as the main development of this interface has been completed.
+ The interface can be changed to add new features, but the
+ current interface will not break by doing this, unless grave
+ errors or security problems are found in them. Userspace
+ programs can start to rely on these interfaces, but they must be
+ aware of changes that can occur before these interfaces move to
+ be marked stable. Programs that use these interfaces are
+ strongly encouraged to add their name to the description of
+ these interfaces, so that the kernel developers can easily
+ notify them if any changes occur (see the description of the
+ layout of the files below for details on how to do this.)
+
+ obsolete/
+ This directory documents interfaces that are still remaining in
+ the kernel, but are marked to be removed at some later point in
+ time. The description of the interface will document the reason
+ why it is obsolete and when it can be expected to be removed.
+
+ removed/
+ This directory contains a list of the old interfaces that have
+ been removed from the kernel.
+
+Every file in these directories will contain the following information:
+
+What: Short description of the interface
+Date: Date created
+KernelVersion: Kernel version this feature first showed up in.
+Contact: Primary contact for this interface (may be a mailing list)
+Description: Long description of the interface and how to use it.
+Users: All users of this interface who wish to be notified when
+ it changes. This is very important for interfaces in
+ the "testing" stage, so that kernel developers can work
+ with userspace developers to ensure that things do not
+ break in ways that are unacceptable. It is also
+ important to get feedback for these interfaces to make
+ sure they are working in a proper way and do not need to
+ be changed further.
+
+
+How things move between levels:
+
+Interfaces in stable may move to obsolete, as long as the proper
+notification is given.
+
+Interfaces may be removed from obsolete and the kernel as long as the
+documented amount of time has gone by.
+
+Interfaces in the testing state can move to the stable state when the
+developers feel they are finished. They cannot be removed from the
+kernel tree without going through the obsolete state first.
+
+It's up to the developer to place their interfaces in the category they
+wish for it to start out in.

+Date: March 2007
+KernelVersion: 2.6.21
+Contact: Alan Stern <stern@rowland.harvard.edu>
+Description:
+ Each USB device directory will contain a file named
+ power/level. This file holds a power-level setting for
+ the device, either "on" or "auto".
+
+ "on" means that the device is not allowed to autosuspend,
+ although normal suspends for system sleep will still
+ be honored. "auto" means the device will autosuspend
+ and autoresume in the usual manner, according to the
+ capabilities of its driver.
+
+ During normal use, devices should be left in the "auto"
+ level. The "on" level is meant for administrative uses.
+ If you want to suspend a device immediately but leave it
+ free to wake up in response to I/O requests, you should
+ write "0" to power/autosuspend.
+
+ Device not capable of proper suspend and resume should be
+ left in the "on" level. Although the USB spec requires
+ devices to support suspend/resume, many of them do not.
+ In fact so many don't that by default, the USB core
+ initializes all non-hub devices in the "on" level. Some
+ drivers may change this setting when they are bound.
+
+ This file is deprecated and will be removed after 2010.
+ Use the power/control file instead; it does exactly the
+ same thing.

+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.

+What: /sys/class/misc/tpmX/device/active
+Date: April 2006
+KernelVersion: 2.6.17
+Contact: tpmdd-devel@lists.sf.net
+Description: The "active" property prints a '1' if the TPM chip is accepting
+ commands. An inactive TPM chip still contains all the state of
+ an active chip (Storage Root Key, NVRAM, etc), and can be
+ visible to the OS, but will only accept a restricted set of

+
+ Example output:
+
+ Manufacturer: 0x53544d20
+ TCG version: 1.2
+ Firmware version: 8.16
+
+ Manufacturer is a hex dump of the 4 byte manufacturer info
+ space in a TPM. TCG version shows the TCG TPM spec level that

+ is manufacturer specific.
+
+What: /sys/class/misc/tpmX/device/durations
+Date: March 2011
+KernelVersion: 3.1
+Contact: tpmdd-devel@lists.sf.net
+Description: The "durations" property shows the 3 vendor-specific values
+ used to wait for a short, medium and long TPM command. All
+ TPM commands are categorized as short, medium or long in
+ execution time, so that the driver doesn't have to wait
+ any longer than necessary before starting to poll for a
+ result.
+
+ Example output:
+
+ 3015000 4508000 180995000 [original]
+
+ 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
+ scaled to be displayed in usecs. In this case "[adjusted]"
+ will be displayed in place of "[original]".

+What: /sys/class/misc/tpmX/device/pcrs
+Date: April 2005
+KernelVersion: 2.6.12
+Contact: tpmdd-devel@lists.sf.net
+Description: The "pcrs" property will dump the current value of all Platform
+ Configuration Registers in the TPM. Note that since these
+ values may be constantly changing, the output is only valid
+ for a snapshot in time.
+
+ Example output:
+
+ PCR-00: 3A 3F 78 0F 11 A4 B4 99 69 FC AA 80 CD 6E 39 57 C3 3B 22 75

+
+ The number of PCRs and hex bytes needed to represent a PCR
+ value will vary depending on TPM chip version. For TPM 1.1 and

+Contact: tpmdd-devel@lists.sf.net
+Description: The "pubek" property will return the TPM's public endorsement
+ key if possible. If the TPM has had ownership established and
+ is version 1.2, the pubek will not be available without the
+ owner's authorization. Since the TPM driver doesn't store any

+ conforms to.
+
+ Example output:
+
+ 750000 750000 750000 750000 [original]
+
+ The four timeout values are shown in usecs, with a trailing

+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).

+Description:
+ This directory exposes interfaces for interactive with
+ EFI variables. For more information on EFI variables,
+ see 'Variable Services' in the UEFI specification
+ (section 7.2 in specification version 2.3 Errata D).
+
+ In summary, EFI variables are named, and are classified
+ into separate namespaces through the use of a vendor
+ GUID. They also have an arbitrary binary value
+ associated with them.
+
+ The efivars module enumerates these variables and
+ creates a separate directory for each one found. Each
+ directory has a name of the form "<key>-<vendor guid>"
+ and contains the following files:
+
+ attributes: A read-only text file enumerating the
+ EFI variable flags. Potential values
+ include:
+
+ EFI_VARIABLE_NON_VOLATILE
+ EFI_VARIABLE_BOOTSERVICE_ACCESS
+ EFI_VARIABLE_RUNTIME_ACCESS
+ EFI_VARIABLE_HARDWARE_ERROR_RECORD
+ EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS
+
+ See the EFI documentation for an
+ explanation of each of these variables.
+
+ data: A read-only binary file that can be read
+ to attain the value of the EFI variable
+
+ guid: The vendor GUID of the variable. This
+ should always match the GUID in the
+ variable's name.
+
+ raw_var: A binary file that can be read to obtain
+ a structure that contains everything
+ there is to know about the variable.
+ For structure definition see "struct
+ efi_variable" in the kernel sources.
+
+ This file can also be written to in
+ order to update the value of a variable.
+ For this to work however, all fields of
+ the "struct efi_variable" passed must
+ match byte for byte with the structure
+ read out of the file, save for the value
+ portion.
+
+ **Note** the efi_variable structure
+ read/written with this file contains a
+ 'long' type that may change widths
+ depending on your underlying
+ architecture.
+
+ size: As ASCII representation of the size of
+ the variable's value.
+
+
+ In addition, two other magic binary files are provided
+ in the top-level directory and are used for adding and
+ removing variables:
+
+ new_var: Takes a "struct efi_variable" and
+ instructs the EFI firmware to create a
+ new variable.
+
+ del_var: Takes a "struct efi_variable" and
+ instructs the EFI firmware to remove any
+ variable that has a matching vendor GUID
+ and variable key name.

+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 Documentation/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.)

+Date: Mai 2012
+KernelVersion: 3.5
+Contact: Kay Sievers <kay@vrfy.org>
+Description: The /dev/kmsg character device node provides userspace access
+ to the kernel's printk buffer.
+
+ Injecting messages:
+ Every write() to the opened device node places a log entry in
+ the kernel's printk buffer.
+
+ The logged line can be prefixed with a <N> syslog prefix, which
+ carries the syslog priority and facility. The single decimal
+ prefix number is composed of the 3 lowest bits being the syslog
+ priority and the higher bits the syslog facility number.
+
+ If no prefix is given, the priority number is the default kernel
+ log priority and the facility number is set to LOG_USER (1). It
+ is not possible to inject messages from userspace with the
+ facility number LOG_KERN (0), to make sure that the origin of
+ the messages can always be reliably determined.
+
+ Accessing the buffer:
+ Every read() from the opened device node receives one record
+ of the kernel's printk buffer.
+
+ The first read() directly following an open() always returns
+ first message in the buffer; there is no kernel-internal
+ persistent state; many readers can concurrently open the device
+ and read from it, without affecting other readers.
+
+ Every read() will receive the next available record. If no more
+ records are available read() will block, or if O_NONBLOCK is
+ used -EAGAIN returned.
+
+ Messages in the record ring buffer get overwritten as whole,
+ there are never partial messages received by read().
+
+ In case messages get overwritten in the circular buffer while
+ the device is kept open, the next read() will return -EPIPE,
+ and the seek position be updated to the next available record.
+ Subsequent reads() will return available records again.
+
+ Unlike the classic syslog() interface, the 64 bit record
+ sequence numbers allow to calculate the amount of lost
+ messages, in case the buffer gets overwritten. And they allow
+ to reconnect to the buffer and reconstruct the read position
+ if needed, without limiting the interface to a single reader.
+
+ The device supports seek with the following parameters:
+ SEEK_SET, 0
+ seek to the first entry in the buffer
+ SEEK_END, 0
+ seek after the last entry in the buffer
+ SEEK_DATA, 0
+ seek after the last record available at the time
+ the last SYSLOG_ACTION_CLEAR was issued.
+
+ The output format consists of a prefix carrying the syslog
+ prefix including priority and facility, the 64 bit message
+ sequence number and the monotonic timestamp in microseconds,
+ and a flag field. All fields are separated by a ','.
+
+ Future extensions might add more comma separated values before
+ the terminating ';'. Unknown fields and values should be
+ gracefully ignored.
+
+ The human readable text string starts directly after the ';'
+ and is terminated by a '\n'. Untrusted values derived from
+ hardware or other facilities are printed, therefore
+ all non-printable characters and '\' itself in the log message
+ are escaped by "\x00" C-style hex encoding.
+
+ A line starting with ' ', is a continuation line, adding
+ key/value pairs to the log message, which provide the machine
+ readable context of the message, for reliable processing in
+ userspace.
+
+ Example:
+ 7,160,424069,-;pci_root PNP0A03:00: host bridge window [io 0x0000-0x0cf7] (ignored)
+ SUBSYSTEM=acpi
+ DEVICE=+acpi:PNP0A03:00
+ 6,339,5140900,-;NET: Registered protocol family 10
+ 30,340,5690716,-;udevd[80]: starting version 181
+
+ The DEVICE= key uniquely identifies devices the following way:
+ b12:8 - block dev_t
+ c127:3 - char dev_t
+ n8 - netdev ifindex
+ +sound:card0 - subsystem:devname
+
+ The flags field carries '-' by default. A 'c' indicates a
+ fragment of a line. All following fragments are flagged with
+ '+'. Note, that these hints about continuation lines are not
+ necessarily correct, and the stream could be interleaved with
+ unrelated messages, but merging the lines in the output
+ usually produces better human readable results. A similar
+ logic is used internally when messages are printed to the
+ console, /proc/kmsg or the syslog() syscall.

+Description: Generic interface to platform dependent persistent storage.
+
+ Platforms that provide a mechanism to preserve some data
+ across system reboots can register with this driver to
+ provide a generic interface to show records captured in
+ the dying moments. In the case of a panic the last part
+ of the console log is captured, but other interesting
+ data can also be saved.
+
+ # mount -t pstore -o kmsg_bytes=8000 - /sys/fs/pstore
+
+ $ ls -l /sys/fs/pstore/
+ total 0
+ -r--r--r-- 1 root root 7896 Nov 30 15:38 dmesg-erst-1
+
+ Different users of this interface will result in different
+ filename prefixes. Currently two are defined:
+
+ "dmesg" - saved console log
+ "mce" - architecture dependent data from fatal h/w error
+
+ Once the information in a file has been read, removing
+ the file will signal to the underlying persistent storage
+ device that it can reclaim the space for later re-use.
+
+ $ rm /sys/fs/pstore/dmesg-erst-1
+
+ The expectation is that all files in /sys/fs/pstore/
+ will be saved elsewhere and erased from persistent store
+ soon after boot to free up space ready for the next
+ catastrophe.
+
+ The 'kmsg_bytes' mount option changes the target amount of
+ data saved on each oops/panic. Pstore saves (possibly
+ multiple) files based on the record size of the underlying
+ persistent storage until at least this amount is reached.
+ Default is 10 Kbytes.
+
+ Pstore only supports one backend at a time. If multiple
+ backends are available, the preferred backend may be
+ set by passing the pstore.backend= argument to the kernel at
+ boot time.

+What: /sys/block/<disk>/queue/discard_max_bytes
+Date: May 2011
+Contact: Martin K. Petersen <martin.petersen@oracle.com>
+Description:
+ Devices that support discard functionality may have
+ internal limits on the number of bytes that can be
+ trimmed or unmapped in a single operation. Some storage
+ protocols also have inherent limits on the number of
+ blocks that can be described in a single command. The
+ discard_max_bytes parameter is set by the device driver
+ to the maximum number of bytes that can be discarded in
+ a single operation. Discard requests issued to the
+ device must not exceed this limit. A discard_max_bytes
+ value of 0 means that the device does not support
+ discard functionality.
+
+What: /sys/block/<disk>/queue/discard_zeroes_data
+Date: May 2011
+Contact: Martin K. Petersen <martin.petersen@oracle.com>
+Description:
+ Devices that support discard functionality may return
+ stale or random data when a previously discarded block
+ is read back. This can cause problems if the filesystem
+ expects discarded blocks to be explicitly cleared. If a
+ device reports that it deterministically returns zeroes
+ when a discarded area is read the discard_zeroes_data
+ parameter will be set to one. Otherwise it will be 0 and
+ the result of reading a discarded area is undefined.
+
+What: /sys/block/<disk>/queue/write_same_max_bytes
+Date: January 2012
+Contact: Martin K. Petersen <martin.petersen@oracle.com>
+Description:
+ Some devices support a write same operation in which a
+ single data block can be written to a range of several
+ contiguous blocks on storage. This can be used to wipe
+ areas on disk or to initialize drives in a RAID
+ configuration. write_same_max_bytes indicates how many
+ bytes can be written in a single write same command. If
+ write_same_max_bytes is 0, write same is not supported
+ by the device.

+Description:
+ Description of the scan element data storage within the buffer
+ and hence the form in which it is read from user-space.
+ Form is [be|le]:[s|u]bits/storagebits[>>shift].
+ be or le specifies big or little endian. s or u specifies if
+ signed (2's complement) or unsigned. bits is the number of bits
+ of data and storagebits is the space (after padding) that it
+ occupies in the buffer. shift if specified, is the shift that
+ needs to be applied prior to masking out unused bits. Some
+ devices put their data in the middle of the transferred elements
+ with additional information on both sides. Note that some
+ devices will have additional information in the unused bits
+ so to get a clean value, the bits value must be used to mask
+ the buffer output value appropriately. The storagebits value
+ also specifies the data alignment. So s48/64>>2 will be a
+ signed 48 bit integer stored in a 64 bit location aligned to
+ a 64 bit boundary. To obtain the clean value, shift right 2
+ and apply a mask to zero the top 16 bits of the result.
+ For other storage combinations this attribute will be extended
+ appropriately.

+ of VFs that should be enabled on the PF; the value written
+ should be less than or equal to the value in the sriov_totalvfs

+ write a zero to this file. The core ensures that valid values
+ are written to this file, and returns errors when values are not
+ valid. For example, writing a 2 to this file when sriov_numvfs
+ is not 0 and not 2 already will return an error. Writing a 10
+ when the value of sriov_totalvfs is 8 will return an error.

+Description:
+ PCI-based EHCI USB controllers (i.e., high-speed USB-2.0
+ controllers) are often implemented along with a set of
+ "companion" full/low-speed USB-1.1 controllers. When a
+ high-speed device is plugged in, the connection is routed
+ to the EHCI controller; when a full- or low-speed device
+ is plugged in, the connection is routed to the companion
+ controller.
+
+ Sometimes you want to force a high-speed device to connect
+ at full speed, which can be accomplished by forcing the
+ connection to be routed to the companion controller.
+ That's what this file does. Writing a port number to the
+ file causes connections on that port to be routed to the
+ companion controller, and writing the negative of a port
+ number returns the port to normal operation.
+
+ For example: To force the high-speed device attached to
+ port 4 on bus 2 to run at full speed:
+
+ echo 4 >/sys/bus/usb/devices/usb2/../companion
+
+ To return the port to high-speed operation:
+
+ echo -4 >/sys/bus/usb/devices/usb2/../companion
+
+ Reading the file gives the list of ports currently forced
+ to the companion controller.
+
+ Note: Some EHCI controllers do not have companions; they
+ may contain an internal "transaction translator" or they
+ may be attached directly to a "rate-matching hub". This
+ mechanism will not work with such controllers. Also, it
+ cannot be used to force a port on a high-speed hub to
+ connect at full speed.
+
+ Note: When this file was first added, it appeared in a
+ different sysfs directory. The location given above is
+ correct for 2.6.35 (and probably several earlier kernel
+ versions as well).

+
+ Under normal circumstances each device is given a part of the

+ writeout speed in relation to the other devices.
+
+ The 'min_ratio' parameter allows assigning a minimum
+ percentage of the write-back cache to a particular device.
+ For example, this is useful for providing a minimum QoS.
+
+max_ratio (read-write)
+
+ Allows limiting a particular device to use not more than the

+ situations where we want to avoid one device taking all or
+ most of the write-back cache. For example in case of an NFS
+ mount that is prone to get stuck, or a FUSE mount which cannot
+ be trusted to play fair.
+
+stable_pages_required (read-only)
+
+ If set, the backing device requires that all pages comprising a write

+Description:
+ This allows the user to examine and adjust the criteria by which
+ mtd returns -EUCLEAN from mtd_read() and mtd_read_oob(). If the
+ maximum number of bit errors that were corrected on any single
+ region comprising an ecc step (as reported by the driver) equals
+ or exceeds this value, -EUCLEAN is returned. Otherwise, absent
+ an error, 0 is returned. Higher layers (e.g., UBI) use this
+ return code as an indication that an erase block may be
+ degrading and should be scrutinized as a candidate for being
+ marked as bad.
+
+ The initial value may be specified by the flash device driver.
+ If not, then the default value is ecc_strength.
+
+ The introduction of this feature brings a subtle change to the
+ meaning of the -EUCLEAN return code. Previously, it was
+ interpreted to mean simply "one or more bit errors were
+ corrected". Its new interpretation can be phrased as "a
+ dangerously high number of bit errors were corrected on one or
+ more regions comprising an ecc step". The precise definition of
+ "dangerously high" can be adjusted by the user with
+ bitflip_threshold. Users are discouraged from doing this,
+ however, unless they know what they are doing and have intimate
+ knowledge of the properties of their device. Broadly speaking,
+ bitflip_threshold should be low enough to detect genuine erase
+ block degradation, but high enough to avoid the consequences of
+ a persistent return value of -EUCLEAN on devices where sticky
+ bitflips occur. Note that if bitflip_threshold exceeds
+ ecc_strength, -EUCLEAN is never returned by the read operations.
+ Conversely, if bitflip_threshold is zero, -EUCLEAN is always
+ returned, absent a hard error.
+
+ This is generally applicable only to NAND flash devices with ECC
+ capability. It is ignored on devices lacking ECC capability;
+ i.e., devices for which ecc_strength is zero.

+sysfs interface
+---------------
+
+The pktcdvd module (packet writing driver) creates
+these files in the sysfs:
+(<devid> is in format major:minor )
+
+/sys/class/pktcdvd/
+ add (0200) Write a block device id (major:minor)
+ to create a new pktcdvd device and map
+ it to the block device.
+
+ remove (0200) Write the pktcdvd device id (major:minor)
+ to it to remove the pktcdvd device.
+
+ device_map (0444) Shows the device mapping in format:
+ pktcdvd[0-7] <pktdevid> <blkdevid>
+
+/sys/class/pktcdvd/pktcdvd[0-7]/
+ dev (0444) Device id
+ uevent (0200) To send an uevent.
+
+/sys/class/pktcdvd/pktcdvd[0-7]/stat/
+ packets_started (0444) Number of started packets.
+ packets_finished (0444) Number of finished packets.
+
+ kb_written (0444) kBytes written.
+ kb_read (0444) kBytes read.
+ kb_read_gather (0444) kBytes read to fill write packets.
+
+ reset (0200) Write any value to it to reset
+ pktcdvd device statistic values, like
+ bytes read/written.
+
+/sys/class/pktcdvd/pktcdvd[0-7]/write_queue/
+ size (0444) Contains the size of the bio write
+ queue.
+
+ congestion_off (0644) If bio write queue size is below
+ this mark, accept new bio requests
+ from the block layer.
+
+ congestion_on (0644) If bio write queue size is higher
+ as this mark, do no longer accept
+ bio write requests from the block
+ layer and wait till the pktcdvd
+ device has processed enough bio's
+ so that bio write queue size is
+ below congestion off mark.
+ A value of <= 0 disables congestion
+ control.
+
+
+Example:
+--------
+To use the pktcdvd sysfs interface directly, you can do:
+
+# create a new pktcdvd device mapped to /dev/hdc
+echo "22:0" >/sys/class/pktcdvd/add
+cat /sys/class/pktcdvd/device_map
+# assuming device pktcdvd0 was created, look at stat's
+cat /sys/class/pktcdvd/pktcdvd0/stat/kb_written
+# print the device id of the mapped block device
+fgrep pktcdvd0 /sys/class/pktcdvd/device_map
+# remove device, using pktcdvd0 device id 253:0
+echo "253:0" >/sys/class/pktcdvd/remove

+Date: April 2008
+KernelVersion: 2.6.26
+Contact: Liam Girdwood <lrg@slimlogic.co.uk>
+Description:
+ Some regulator directories will contain a field called
+ state. This reports the regulator enable control, for
+ regulators which can report that input value.
+
+ This will be one of the following strings:
+
+ 'enabled'
+ 'disabled'
+ 'unknown'
+
+ 'enabled' means the regulator output is ON and is supplying
+ power to the system (assuming no error prevents it).
+
+ 'disabled' means the regulator output is OFF and is not
+ supplying power to the system (unless some non-Linux
+ control has enabled it).
+
+ 'unknown' means software cannot determine the state, or

+
+ NOTE: this field can be used in conjunction with microvolts
+ or microamps to determine configured regulator output levels.

+
+What: /sys/class/regulator/.../status
+Description:

+ regulators which can report that output value.
+
+ This will be one of the following strings:
+
+ off
+ on
+ error
+ fast
+ normal
+ idle
+ standby
+
+ "off" means the regulator is not supplying power to the
+ system.
+
+ "on" means the regulator is supplying power to the system,
+ and the regulator can't report a detailed operation mode.
+
+ "error" indicates an out-of-regulation status such as being
+ disabled due to thermal shutdown, or voltage being unstable
+ because of problems with the input power supply.
+
+ "fast", "normal", "idle", and "standby" are all detailed
+ regulator operation modes (described elsewhere). They
+ imply "on", but provide more detail.
+
+ Note that regulator status is a function of many inputs,
+ not limited to control inputs from Linux. For example,
+ the actual load presented may trigger "error" status; or
+ a regulator may be enabled by another user, even though
+ Linux did not enable it.

+What: /sys/devices/.../power/
+Date: January 2009
+Contact: Rafael J. Wysocki <rjw@sisk.pl>
+Description:
+ The /sys/devices/.../power directory contains attributes
+ allowing the user space to check and modify some power
+ management related properties of given device.
+
+What: /sys/devices/.../power/wakeup
+Date: January 2009
+Contact: Rafael J. Wysocki <rjw@sisk.pl>
+Description:
+ The /sys/devices/.../power/wakeup attribute allows the user
+ space to check if the device is enabled to wake up the system
+ from sleep states, such as the memory sleep state (suspend to
+ RAM) and hibernation (suspend to disk), and to enable or disable
+ it to do that as desired.
+
+ Some devices support "wakeup" events, which are hardware signals
+ used to activate the system from a sleep state. Such devices
+ have one of the following two values for the sysfs power/wakeup
+ file:
+
+ + "enabled\n" to issue the events;
+ + "disabled\n" not to do so;
+
+ In that cases the user space can change the setting represented
+ by the contents of this file by writing either "enabled", or
+ "disabled" to it.
+
+ For the devices that are not capable of generating system wakeup
+ events this file is not present. In that case the device cannot
+ be enabled to wake up the system from sleep states.
+
+What: /sys/devices/.../power/control
+Date: January 2009
+Contact: Rafael J. Wysocki <rjw@sisk.pl>
+Description:
+ The /sys/devices/.../power/control attribute allows the user
+ space to control the run-time power management of the device.
+
+ All devices have one of the following two values for the
+ power/control file:
+
+ + "auto\n" to allow the device to be power managed at run time;
+ + "on\n" to prevent the device from being power managed;
+
+ The default for all devices is "auto", which means that they may
+ be subject to automatic power management, depending on their
+ drivers. Changing this attribute to "on" prevents the driver
+ from power managing the device at run time. Doing that while
+ the device is suspended causes it to be woken up.
+
+What: /sys/devices/.../power/async
+Date: January 2009
+Contact: Rafael J. Wysocki <rjw@sisk.pl>
+Description:
+ The /sys/devices/.../async attribute allows the user space to
+ enable or diasble the device's suspend and resume callbacks to
+ be executed asynchronously (ie. in separate threads, in parallel
+ with the main suspend/resume thread) during system-wide power
+ transitions (eg. suspend to RAM, hibernation).
+
+ All devices have one of the following two values for the
+ power/async file:
+
+ + "enabled\n" to permit the asynchronous suspend/resume;
+ + "disabled\n" to forbid it;
+
+ The value of this attribute may be changed by writing either
+ "enabled", or "disabled" to it.
+
+ It generally is unsafe to permit the asynchronous suspend/resume
+ of a device unless it is certain that all of the PM dependencies
+ of the device are known to the PM core. However, for some
+ devices this attribute is set to "enabled" by bus type code or
+ device drivers and in that cases it should be safe to leave the
+ default value.

+What: /sys/devices/.../power/autosuspend_delay_ms
+Date: September 2010
+Contact: Alan Stern <stern@rowland.harvard.edu>
+Description:
+ The /sys/devices/.../power/autosuspend_delay_ms attribute
+ contains the autosuspend delay value (in milliseconds). Some
+ drivers do not want their device to suspend as soon as it
+ becomes idle at run time; they want the device to remain
+ inactive for a certain minimum period of time first. That
+ period is called the autosuspend delay. Negative values will
+ prevent the device from being suspended at run time (similar
+ to writing "on" to the power/control attribute). Values >=
+ 1000 will cause the autosuspend timer expiration to be rounded
+ up to the nearest second.
+
+ Not all drivers support this attribute. If it isn't supported,
+ attempts to read or write it will yield I/O errors.

+ in microseconds. If it is equal to 0, however, this means that
+ the PM QoS resume latency may be arbitrary.
+
+ Not all drivers support this attribute. If it isn't supported,
+ it is not present.
+
+ This attribute has no effect on system-wide suspend/resume and
+ hibernation.

+
+ One cpu# directory is created per logical CPU in the system,

+
+ Briefly, the files above are:
+
+ core_id: the CPU core ID of cpu#. Typically it is the
+ hardware platform's identifier (rather than the kernel's).
+ The actual value is architecture and platform dependent.
+
+ core_siblings: internal kernel map of cpu#'s hardware threads
+ within the same physical_package_id.
+
+ core_siblings_list: human-readable list of the logical CPU
+ numbers within the same physical_package_id as cpu#.
+
+ physical_package_id: physical package id of cpu#. Typically
+ corresponds to a physical socket number, but the actual value

+
+ There are many knobs to tweak in this directory.

+Description: Disable L3 cache indices
+
+ These files exist in every CPU's cache/index3 directory. Each
+ cache_disable_{0,1} file corresponds to one disable slot which
+ can be used to disable a cache index. Reading from these files
+ on a processor with this functionality will return the currently
+ disabled index for that node. There is one L3 structure per
+ node, or per internal node on MCM machines. Writing a valid
+ index to one of these files will cause the specificed cache
+ index to be disabled.
+
+ All AMD processors with L3 caches provide this functionality.
