+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  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., 59 Temple Place, Suite 330, Boston, MA  02111-1307  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.

+The cpufrequtils package (homepage: 
+http://www.kernel.org/pub/linux/utils/kernel/cpufreq/cpufrequtils.html ) 
+consists of the following elements:
+
+requirements
+------------
+
+On x86 pciutils is needed at runtime (-lpci).
+For compilation pciutils-devel (pci/pci.h) and a gcc version
+providing cpuid.h is needed.
+For both it's not explicitly checked for (yet).
+
+
+libcpufreq
+----------
+
+"libcpufreq" is a library which offers a unified access method for userspace
+tools and programs to the cpufreq core and drivers in the Linux kernel. This
+allows for code reduction in userspace tools, a clean implementation of
+the interaction to the cpufreq core, and support for both the sysfs and proc
+interfaces [depending on configuration, see below].
+
+
+compilation and installation
+----------------------------
+
+make
+su
+make install
+
+should suffice on most systems. It builds default libcpufreq,
+cpufreq-set and cpufreq-info files and installs them in /usr/lib and
+/usr/bin, respectively. If you want to set up the paths differently and/or
+want to configure the package to your specific needs, you need to open
+"Makefile" with an editor of your choice and edit the block marked
+CONFIGURATION.
+
+
+THANKS
+------
+Many thanks to Mattia Dongili who wrote the autotoolization and
+libtoolization, the manpages and the italian language file for cpufrequtils;
+to Dave Jones for his feedback and his dump_psb tool; to Bruno Ducrot for his
+powernow-k8-decode and intel_gsic tools as well as the french language file;
+and to various others commenting on the previous (pre-)releases of 
+cpufrequtils.

+This is cpufreq-bench, a microbenchmark for the cpufreq framework.
+
+Purpose
+=======
+
+What is this benchmark for:
+  - Identify worst case performance loss when doing dynamic frequency
+    scaling using Linux kernel governors
+  - Identify average reaction time of a governor to CPU load changes
+  - (Stress) Testing whether a cpufreq low level driver or governor works
+    as expected
+  - Identify cpufreq related performance regressions between kernels
+  - Possibly Real time priority testing? -> what happens if there are
+    processes with a higher prio than the governor's kernel thread
+  - ...
+
+What this benchmark does *not* cover:
+  - Power saving related regressions (In fact as better the performance
+    throughput is, the worse the power savings will be, but the first should
+    mostly count more...)
+  - Real world (workloads)
+
+
+Description
+===========
+
+cpufreq-bench helps to test the condition of a given cpufreq governor.
+For that purpose, it compares the performance governor to a configured
+powersave module.
+
+
+How it works
+============
+You can specify load (100% CPU load) and sleep (0% CPU load) times in us which
+will be run X time in a row (cycles):
+
+         sleep=25000
+         load=25000
+         cycles=20
+
+This part of the configuration file will create 25ms load/sleep turns,
+repeated 20 times.
+
+Adding this:
+         sleep_step=25000
+         load_step=25000
+         rounds=5
+Will increase load and sleep time by 25ms 5 times.
+Together you get following test:
+25ms  load/sleep time repeated 20 times (cycles).
+50ms  load/sleep time repeated 20 times (cycles).
+..
+100ms load/sleep time repeated 20 times (cycles).
+
+First it is calibrated how long a specific CPU intensive calculation
+takes on this machine and needs to be run in a loop using the performance
+governor.
+Then the above test runs are processed using the performance governor
+and the governor to test. The time the calculation really needed
+with the dynamic freq scaling governor is compared with the time needed
+on full performance and you get the overall performance loss.
+
+
+Example of expected results with ondemand governor:
+
+This shows expected results of the first two test run rounds from
+above config, you there have:
+
+100% CPU load (load) | 0 % CPU load (sleep)  | round
+   25 ms             |    25 ms              |   1
+   50 ms             |    50 ms              |   2
+
+For example if ondemand governor is configured to have a 50ms
+sampling rate you get:
+
+In round 1, ondemand should have rather static 50% load and probably
+won't ever switch up (as long as up_threshold is above).
+
+In round 2, if the ondemand sampling times exactly match the load/sleep
+trigger of the cpufreq-bench, you will see no performance loss (compare with
+below possible ondemand sample kick ins (1)):
+
+But if ondemand always kicks in in the middle of the load sleep cycles, it
+will always see 50% loads and you get worst performance impact never
+switching up (compare with below possible ondemand sample kick ins (2))::
+
+      50     50   50   50ms ->time
+load -----|     |-----|     |-----|     |-----|
+          |     |     |     |     |     |     |
+sleep     |-----|     |-----|     |-----|     |----
+    |-----|-----|-----|-----|-----|-----|-----|----  ondemand sampling (1)
+         100    0    100    0    100    0    100     load seen by ondemand(%)
+       |-----|-----|-----|-----|-----|-----|-----|--   ondemand sampling (2)
+      50     50    50    50    50    50    50        load seen by ondemand(%)
+
+You can easily test all kind of load/sleep times and check whether your
+governor in average behaves as expected.
+
+
+ToDo
+====
+
+Provide a gnuplot utility script for easy generation of plots to present
+the outcome nicely.

+
+.SH MONITOR DESCRIPTIONS
+.SS "Idle_Stats"
+Shows statistics of the cpuidle kernel subsystem. Values are retrieved from
+/sys/devices/system/cpu/cpu*/cpuidle/state*/.
+The kernel updates these values every time an idle state is entered or
+left. Therefore there can be some inaccuracy when cores are in an idle
+state for some time when the measure starts or ends. In worst case it can happen
+that one core stayed in an idle state for the whole measure time and the idle
+state usage time as exported by the kernel did not get updated. In this case
+a state residency of 0 percent is shown while it was 100.
+
+.SS "Mperf"
+The name comes from the aperf/mperf (average and maximum) MSR registers used
+which are available on recent X86 processors. It shows the average frequency
+(including boost frequencies).
+The fact that on all recent hardware the mperf timer stops ticking in any idle
+state it is also used to show C0 (processor is active) and Cx (processor is in
+any sleep state) times. These counters do not have the inaccuracy restrictions
+the "Idle_Stats" counters may show.
+May work poorly on Linux-2.6.20 through 2.6.29, as the \fBacpi-cpufreq \fP
+kernel frequency driver periodically cleared aperf/mperf registers in those
+kernels.
+
+.SS "Nehalem" "SandyBridge"
+Intel Core and Package sleep state counters.
+Threads (hyperthreaded cores) may not be able to enter deeper core states if
+its sibling is utilized.
+Deepest package sleep states may in reality show up as machine/platform wide
+sleep states and can only be entered if all cores are idle. Look up Intel
+manuals (some are provided in the References section) for further details.
+
+.SS "Ontario" "Liano"
+AMD laptop and desktop processor (family 12h and 14h) sleep state counters.
+The registers are accessed via PCI and therefore can still be read out while
+cores have been offlined.
+
+There is one special counter: NBP1 (North Bridge P1).
+This one always returns 0 or 1, depending on whether the North Bridge P1
+power state got entered at least once during measure time.
+Being able to enter NBP1 state also depends on graphics power management.
+Therefore this counter can be used to verify whether the graphics' driver
+power management is working as expected.
+
+.SH EXAMPLES
+
+cpupower monitor -l" may show:
+.RS 4
+Monitor "Mperf" (3 states) \- Might overflow after 922000000 s
+
+   ...
+
+Monitor "Idle_Stats" (3 states) \- Might overflow after 4294967295 s
+
+   ...
+
+.RE
+cpupower monitor \-m "Idle_Stats,Mperf" scp /tmp/test /nfs/tmp
+
+Monitor the scp command, show both Mperf and Idle_Stats states counter
+statistics, but in exchanged order.
+
+
+
+.RE
+Be careful that the typical command to fully utilize one CPU by doing:
+
+cpupower monitor cat /dev/zero >/dev/null
+
+Does not work as expected, because the measured output is redirected to
+/dev/null. This could get workarounded by putting the line into an own, tiny
+shell script. Hit CTRL\-c to terminate the command and get the measure output
+displayed.

+.SH SYNOPSIS
+.ft B
+.B cpupower set [ \-b VAL ] [ \-s VAL ] [ \-m VAL ]
+
+
+.SH DESCRIPTION
+\fBcpupower set \fP sets kernel configurations or directly accesses hardware
+registers affecting processor power saving policies.
+
+Some options are platform wide, some affect single cores. By default values
+are applied on all cores. How to modify single core configurations is
+described in the cpupower(1) manpage in the \-\-cpu option section. Whether an
+option affects the whole system or can be applied to individual cores is
+described in the Options sections.
+
+Use \fBcpupower info \fP to read out current settings and whether they are
+supported on the system at all.
+
+.SH Options
+.PP
+\-\-perf-bias, \-b
+.RS 4
+Sets a register on supported Intel processore which allows software to convey
+its policy for the relative importance of performance versus energy savings to
+the  processor.
+
+The range of valid numbers is 0-15, where 0 is maximum
+performance and 15 is maximum energy efficiency.
+
+The processor uses this information in model-specific ways
+when it must select trade-offs between performance and
+energy efficiency.
+
+This policy hint does not supersede Processor Performance states
+(P-states) or CPU Idle power states (C-states), but allows
+software to have influence where it would otherwise be unable
+to express a preference.
+
+For example, this setting may tell the hardware how
+aggressively or conservatively to control frequency
+in the "turbo range" above the explicitly OS-controlled
+P-state frequency range.  It may also tell the hardware
+how aggressively it should enter the OS requested C-states.
+
+This option can be applied to individual cores only via the \-\-cpu option,
+cpupower(1).
+
+Setting the performance bias value on one CPU can modify the setting on
+related CPUs as well (for example all CPUs on one socket), because of
+hardware restrictions.
+Use \fBcpupower -c all info -b\fP to verify.
+
+This options needs the msr kernel driver (CONFIG_X86_MSR) loaded.

+
+The impact on power consumption and performance (positiv or negativ) heavily
+depends on processor support for deep sleep states, frequency scaling and
+frequency boost modes and their dependencies between other thread siblings
+and processor cores.
+
+Taken over from kernel documentation:
+
+Adjust the kernel's multi-core scheduler support.
+
+Possible values are:
+.RS 2
+0 - No power saving load balance (default value)
+
+1 - Fill one thread/core/package first for long running threads
+
+2 - Also bias task wakeups to semi-idle cpu package for power
+savings
+.RE
+
+sched_mc_power_savings is dependent upon SCHED_MC, which is
+itself architecture dependent.
+
+sched_smt_power_savings is dependent upon SCHED_SMT, which
+is itself architecture dependent.
+
+The two files are independent of each other. It is possible
+that one file may be present without the other.

+.SH DESCRIPTION
+\fBcpupower \fP is a collection of tools to examine and tune power saving
+related features of your processor.
+
+The manpages of the subcommands (cpupower\-<subcommand>(1)) provide detailed
+descriptions of supported features. Run \fBcpupower help\fP to get an overview
+of supported subcommands.
+
+.SH Options
+.PP
+\-\-help, \-h
+.RS 4
+Shows supported subcommands and general usage.
+.RE
+.PP
+\-\-cpu cpulist,  \-c cpulist
+.RS 4
+Only show or set values for specific cores.
+This option is not supported by all subcommands, details can be found in the
+manpages of the subcommands.
+
+Some subcommands access all cores (typically the *\-set commands), some only
+the first core (typically the *\-info commands) by default.
+
+The syntax for <cpulist> is based on how the kernel exports CPU bitmasks via
+sysfs files. Some examples:
