+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.

+\-\-sched\-mc utilizes cores in one processor package/socket first before

+
+\-\-sched\-smt utilizes thread siblings of one processor core first before

+
+The impact on power consumption and performance (positiv or negativ) heavily
+depends on processor support for deep sleep states, frequency scaling and

+and processor cores.

+.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.

+\-\-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:
