+The cpupower package 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).
+
+
+libcpupower
+----------
+
+"libcpupower" 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 libcpupower to put in
+/usr/lib; cpupower, cpufreq-bench_plot.sh to put in /usr/bin; and
+cpufreq-bench to put in /usr/sbin. 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 cpupower;
+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 
+cpupower.

+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 IDLE\-INFO DESCRIPTIONS
+CPU sleep state statistics and descriptions are retrieved from sysfs files,
+exported by the cpuidle kernel subsystem. The kernel only updates these
+statistics when it enters or leaves an idle state, therefore on a very idle or
+a very busy system, these statistics may not be accurate. They still provide a
+good overview about the usage and availability of processor sleep states on
+the platform.
+
+Be aware that the sleep states as exported by the hardware or BIOS and used by
+the Linux kernel may not exactly reflect the capabilities of the
+processor. This often is the case on the X86 architecture when the acpi_idle
+driver is used. It is also possible that the hardware overrules the kernel
+requests, due to internal activity monitors or other reasons.
+On recent X86 platforms it is often possible to read out hardware registers
+which monitor the duration of sleep states the processor resided in. The
+cpupower monitor tool (cpupower\-monitor(1)) can be used to show real sleep
+state residencies. Please refer to the architecture specific description
+section below.
+
+.SH IDLE\-INFO ARCHITECTURE SPECIFIC DESCRIPTIONS
+.SS "X86"
+POLL idle state
+
+If cpuidle is active, X86 platforms have one special idle state.
+The POLL idle state is not a real idle state, it does not save any
+power. Instead, a busy\-loop is executed doing nothing for a short period of
+time. This state is used if the kernel knows that work has to be processed
+very soon and entering any real hardware idle state may result in a slight
+performance penalty.
+
+There exist two different cpuidle drivers on the X86 architecture platform:
+
+"acpi_idle" cpuidle driver
+
+The acpi_idle cpuidle driver retrieves available sleep states (C\-states) from
+the ACPI BIOS tables (from the _CST ACPI function on recent platforms or from
+the FADT BIOS table on older ones).
+The C1 state is not retrieved from ACPI tables. If the C1 state is entered,
+the kernel will call the hlt instruction (or mwait on Intel).
+
+"intel_idle" cpuidle driver
+
+In kernel 2.6.36 the intel_idle driver was introduced.
+It only serves recent Intel CPUs (Nehalem, Westmere, Sandybridge, Atoms or
+newer). On older Intel CPUs the acpi_idle driver is still used (if the BIOS
+provides C\-state ACPI tables).
+The intel_idle driver knows the sleep state capabilities of the processor and
+ignores ACPI BIOS exported processor sleep states tables.
+
+.SH "REMARKS"
+.LP
+By default only values of core zero are displayed. How to display settings of
+other cores is described in the cpupower(1) manpage in the \-\-cpu option
+section.

+.LP
+Cpuidle Governors Policy on Disabling Sleep States
+
+.RS 4
+Depending on the used  cpuidle governor, implementing the kernel policy
+how to choose sleep states, subsequent sleep states on this core, might get
+disabled as well.
+
+There are two cpuidle governors ladder and menu. While the ladder
+governor is always available, if CONFIG_CPU_IDLE is selected, the
+menu governor additionally requires CONFIG_NO_HZ.
+
+The behavior and the effect of the disable variable depends on the
+implementation of a particular governor. In the ladder governor, for
+example, it is not coherent, i.e. if one is disabling a light state,
+then all deeper states are disabled as well. Likewise, if one enables a
+deep state but a lighter state still is disabled, then this has no effect.
+.RE
+.LP
+Disabling the Lightest Sleep State may not have any Affect
+
+.RS 4
+If criteria are not met to enter deeper sleep states and the lightest sleep
+state is chosen when idle, the kernel may still enter this sleep state,
+irrespective of whether it is disabled or not. This is also reflected in
+the usage count of the disabled sleep state when using the cpupower idle-info
+command.
+.RE
+.LP
+Selecting specific CPU Cores
+
+.RS 4
+By default processor sleep states of all CPU cores are set. Please refer
+to the cpupower(1) manpage in the \-\-cpu option section how to disable
+C-states of specific cores.

+.SH DESCRIPTION
+\fBcpupower-monitor \fP reports processor topology, frequency and idle power
+state statistics. Either \fBcommand\fP is forked and
+statistics are printed upon its completion, or statistics are printed periodically.
+
+\fBcpupower-monitor \fP implements independent processor sleep state and
+frequency counters. Some are retrieved from kernel statistics, some are
+directly reading out hardware registers. Use \-l to get an overview which are
+supported on your system.
+
+.SH Options

+Schedule the process on every core before starting and ending measuring.
+This could be needed for the Idle_Stats monitor when no other MSR based
+monitor (has to be run on the core that is measured) is run in parallel.
+This is to wake up the processors from deeper sleep states and let the
+kernel re
+-account its cpuidle (C-state) information before reading the
+cpuidle timings from sysfs.
+.RE

+.RS 4
+Measure idle and frequency characteristics of an arbitrary command/workload.
+The executable \fBcommand\fP is forked and upon its exit, statistics gathered since it was
+forked are displayed.

+\-v
+.RS 4
+Increase verbosity if the binary was compiled with the DEBUG option set.
+.RE
+
+.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" "HaswellExtended"
+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.
+The monitors are named after the CPU family where the sleep state capabilities
+got introduced and may not match exactly the CPU name of the platform.
+For example an IvyBridge processor has sleep state capabilities which got
+introduced in Nehalem and SandyBridge processor families.
+Thus on an IvyBridge processor one will get Nehalem and SandyBridge sleep
+state monitors.
+HaswellExtended extra package sleep state capabilities are available only in a
+specific Haswell (family 0x45) and probably also other future processors.
+
+.SS "Fam_12h" "Fam_14h"
+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.

+.B cpupower set [ \-b 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.

+|                          OVERVIEW                              |
+------------------------------------------------------------------
+
+ This tool suite is designed to assist kernel and OS developers in optimizing
+ their linux stack's suspend/resume & boot time. Using a kernel image built
+ with a few extra options enabled, the tools will execute a suspend or boot,
+ and will capture dmesg and ftrace data. This data is transformed into a set of
+ timelines and a callgraph to give a quick and detailed view of which devices
+ and kernel processes are taking the most time in suspend/resume & boot.
+
+------------------------------------------------------------------
+|                            SETUP                               |
+------------------------------------------------------------------
+
+    Package Requirements
+       - runs with python2 or python3, choice is made by /usr/bin/python link
+       - python
+       - python-configparser (for python2 sleepgraph)
+       - python-requests (for stresstester.py)
+       - linux-tools-common (for turbostat usage in sleepgraph)
+
+       Ubuntu:
+          sudo apt-get install python python-configparser python-requests linux-tools-common
+
+       Fedora:
+          sudo dnf install python python-configparser python-requests linux-tools-common
+
+    The tools can most easily be installed via git clone and make install
+
+    $> git clone http://github.com/intel/pm-graph.git
+    $> cd pm-graph
+    $> sudo make install
+    $> man sleepgraph ; man bootgraph
+
+    Setup involves some minor kernel configuration
+
+    The following kernel build options are required for all kernels:
+        CONFIG_DEVMEM=y
+        CONFIG_PM_DEBUG=y
+        CONFIG_PM_SLEEP_DEBUG=y
+        CONFIG_FTRACE=y
+        CONFIG_FUNCTION_TRACER=y
+        CONFIG_FUNCTION_GRAPH_TRACER=y
+        CONFIG_KPROBES=y
+        CONFIG_KPROBES_ON_FTRACE=y
+
+	In kernel 3.15.0, two patches were upstreamed which enable the
+        v3.0 behavior. These patches allow the tool to read all the
+        data from trace events instead of from dmesg. You can enable
+        this behavior on earlier kernels with these patches:
+
+        (kernel/pre-3.15/enable_trace_events_suspend_resume.patch)
+        (kernel/pre-3.15/enable_trace_events_device_pm_callback.patch)
+
+	If you're using bootgraph, or sleepgraph with a kernel older than 3.15.0,
+		the following additional kernel parameters are required:
+        (e.g. in file /etc/default/grub)
+        GRUB_CMDLINE_LINUX_DEFAULT="... initcall_debug log_buf_len=32M ..."
+
+	If you're using a kernel older than 3.11-rc2, the following simple
+		patch must be applied to enable ftrace data:
+        in file: kernel/power/suspend.c
+        in function: int suspend_devices_and_enter(suspend_state_t state)
+        remove call to "ftrace_stop();"
+        remove call to "ftrace_start();"
+
+        There is a patch which does this for kernel v3.8.0:
+        (kernel/pre-3.11-rc2/enable_ftrace_in_suspendresume.patch)
+
+
+
+------------------------------------------------------------------
+|                            USAGE                               |
+------------------------------------------------------------------
+
+Basic Usage
+___________
+
+ 1) First configure a kernel using the instructions from the previous sections.
+    Then build, install, and boot with it.
+ 2) Open up a terminal window and execute the mode list command:
+
+	%> sudo ./sleepgraph.py -modes
+		['freeze', 'mem', 'disk']
+
+ Execute a test using one of the available power modes, e.g. mem (S3):
+
+	%> sudo ./sleepgraph.py -m mem -rtcwake 15
+
+		or with a config file
+
+	%> sudo ./sleepgraph.py -config config/suspend.cfg
+
+ When the system comes back you'll see the script finishing up and
+ creating the output files in the test subdir. It generates output
+ files in subdirectory: suspend-mmddyy-HHMMSS. The ftrace file can
+ be used to regenerate the html timeline with different options
+
+     HTML output:                    <hostname>_<mode>.html
+     raw dmesg output:               <hostname>_<mode>_dmesg.txt
+     raw ftrace output:              <hostname>_<mode>_ftrace.txt
+
+ View the html in firefox or chrome.
+
+
+Dev Mode Usage
+______________
+
+ Developer mode adds information on low level source calls to the timeline.
+ The tool sets kprobes on all delay and mutex calls to see which devices
+ are waiting for something and when. It also sets a suite of kprobes on
+ subsystem dependent calls to better fill out the timeline.
+
+ The tool will also expose kernel threads that don't normally show up in the
+ timeline. This is useful in discovering dependent threads to get a better
+ idea of what each device is waiting for. For instance, the scsi_eh thread,
+ a.k.a. scsi resume error handler, is what each SATA disk device waits for
+ before it can continue resume.
+
+ The timeline will be much larger if run with dev mode, so it can be useful
+ to set the -mindev option to clip out any device blocks that are too small
+ to see easily. The following command will give a nice dev mode run:
+
+ %> sudo ./sleepgraph.py -m mem -rtcwake 15 -mindev 1 -dev
+
+	or with a config file
+
+ %> sudo ./sleepgraph.py -config config/suspend-dev.cfg
+
+
+Proc Mode Usage
+_______________
+
+ Proc mode adds user process info to the timeline. This is done in a manner
+ similar to the bootchart utility, which graphs init processes and their
+ execution as the system boots. This tool option does the same thing but for
+ the period before and after suspend/resume.
+
+ In order to see any process info, there needs to be some delay before or
+ after resume since processes are frozen in suspend_prepare and thawed in
+ resume_complete. The predelay and postdelay args allow you to do this. It
+ can also be useful to run in x2 mode with an x2 delay, this way you can
+ see process activity before and after resume, and in between two
+ successive suspend/resumes.
+
+ The command can be run like this:
+
+ %> sudo ./sleepgraph.py -m mem -rtcwake 15 -x2 -x2delay 1000 -predelay 1000 -postdelay 1000 -proc
+
+	or with a config file
+
+ %> sudo ./sleepgraph.py -config config/suspend-proc.cfg
+
+------------------------------------------------------------------
+|                     ENDURANCE TESTING                          |
+------------------------------------------------------------------
+
+ The best way to gauge the health of a system is to run a series of
+ suspend/resumes over an extended period and analyze the behavior. This can be
+ accomplished with sleepgraph's -multi argument. You specify two numbers: the
+ number of tests to run OR the duration in days, hours, or minutes, and the
+ delay in seconds between them. For instance, -multi 20 5: execute 20 tests with
+ a 5 second delay between each, or -multi 24h 0: execute tests over a 24 hour
+ period with no delay between tests. You can include any other options you like
+ to generate the data you want. It's most useful to collect dev mode timelines
+ as the kprobes don't alter the performance much and you get more insight.
+
+ On completion, the output folder contains a series of folders for the
+ individual test data and a set of summary pages in the root. The summary.html
+ file is a tabular list of the tests with relevant info and links. The
+ summary-issue.html and summary-devices.html files include data taken from
+ all tests on kernel issues and device performance. The folder looks like this:
+
+  suspend-xN-{date}-{time}:
+	summary.html
+	summary-issues.html
+	summary-devices.html
+	suspend-{date}-{time} (1)
+	suspend-{date}-{time} (2)
+	...
+
+ These are the relevant arguments to use for testing:
+
+  -m mode
+	Mode to initiate for suspend e.g. mem, freeze, standby (default: mem).
+
+  -rtcwake t
+	Use rtcwake to autoresume after t seconds (default: 15).
+
+  -gzip (optional)
+	Gzip the trace and dmesg logs to save space. The tool can also read in
+	gzipped logs for processing. This reduces the multitest folder size.
+
+  -dev (optional)
+	Add kernel source calls and threads to the timeline (default: disabled).
+
+  -multi n d
+	Execute n consecutive tests at d seconds intervals. The outputs will be
+	created in a new subdirectory: suspend-xN-{date}-{time}. When the multitest
+	run is done, the -summary command is called automatically to create summary
+	html files for all the data (unless you use -skiphtml). -skiphtml will
+	speed up the testing by not creating timelines or summary html files. You
+	can then run the tool again at a later time with -summary and -genhtml to
+	create the timelines.
+
+  -skiphtml (optional)
+	Run the test and capture the trace logs, but skip the timeline and summary
+	html generation. This can greatly speed up overall testing. You can then
+	copy the data to a faster host machine and run -summary -genhtml to
+	generate the timelines and summary.
+
+ These are the relevant commands to use after testing is complete:
+
+  -summary indir
+	Generate or regenerate the summary for a -multi test run. Creates three
+	files: summary.html, summary-issues.html, and summary-devices.html in the
+	current folder. summary.html is a table of tests with relevant info sorted
+	by kernel/host/mode, and links to the test html files. summary-issues.html
+	is a list of kernel issues found in dmesg from all the tests.
+	summary-devices.html is a list of devices and times from all the tests.
+
+  -genhtml
+	Used  with -summary to regenerate any missing html timelines from their
+	dmesg and ftrace logs. This will require a significant amount of time if
+	there are thousands of tests.
+
+Usage Examples
+_______________
+
+ A multitest is initiated like this:
+
+  %> sudo ./sleepgraph.py -m mem -rtcwake 10 -dev -gzip -multi 2000 0
+
+	or you can skip timeline generation in order to speed things up
+
+  %> sudo ./sleepgraph.py -m mem -rtcwake 10 -dev -gzip -multi 2000 0 -skiphtml
+
+ The tool will produce an output folder with all the test subfolders inside.
+ Each test subfolder contains the dmesg/ftrace logs and/or the html timeline
+ depending on whether you used the -skiphtml option. The root folder contains
+ the summary.html files.
+
+ The summary for an existing multitest is generated like this:
+
+  %> cd suspend-x2000-{date}-{time}
+  %> sleepgraph.py -summary .
+
+	or if you need to generate the html timelines you can use -genhtml
+
+  %> cd suspend-xN-{date}-{time}
+  %> sleepgraph.py -summary . -genhtml
+

+|                    CONFIGURATION FILES                         |
+------------------------------------------------------------------
+
+ Since 4.0 we've moved to using config files in lieu of command line options.
+ The config folder contains a collection of typical use cases.
+ There are corresponding configs for other power modes:
+
+	Simple suspend/resume with basic timeline (mem/freeze/standby)
+		config/suspend.cfg
+		config/freeze.cfg
+		config/standby.cfg
+
+	Dev mode suspend/resume with dev timeline (mem/freeze/standby)
+		config/suspend-dev.cfg
+		config/freeze-dev.cfg
+		config/standby-dev.cfg
+
+	Simple suspend/resume with timeline and callgraph (mem/freeze/standby)
+		config/suspend-callgraph.cfg
+		config/freeze-callgraph.cfg
+		config/standby-callgraph.cfg
+
+	Sample proc mode x2 run using mem suspend
+		config/suspend-x2-proc.cfg
+
+	Sample for editing timeline funcs (moves internal functions into config)
+		config/custom-timeline-functions.cfg
+
+	Sample debug config for serio subsystem
+		config/debug-serio-suspend.cfg
+
+
+Usage Examples
+______________
+
+ Run a simple mem suspend:
+ %> sudo ./sleepgraph.py -config config/suspend.cfg
+
+ Run a mem suspend with callgraph data:
+ %> sudo ./sleepgraph.py -config config/suspend-callgraph.cfg
+
+ Run a mem suspend with dev mode detail:

+
+Adding or Editing Timeline Functions
+____________________________________
+
+ The tool uses an array of function names to fill out empty spaces in the
+ timeline where device callbacks don't appear. For instance, in suspend_prepare
+ the tool adds the sys_sync and freeze_processes calls as virtual device blocks
+ in the timeline to show you where the time is going. These calls should fill
+ the timeline with contiguous data so that most kernel execution is covered.
+
+ It is possible to add new function calls to the timeline by adding them to
+ the config. It's also possible to copy the internal timeline functions into
+ the config so that you can override and edit them. Place them in the
+ timeline_functions_ARCH section with the name of your architecture appended.
+ i.e. for x86_64: [timeline_functions_x86_64]
+
+ Use the override-timeline-functions option if you only want to use your
+ custom calls, or leave it false to append them to the internal ones.
+
+ This section includes a list of functions (set using kprobes) which use both
+ symbol data and function arg data. The args are pulled directly from the
+ stack using this architecture's registers and stack formatting. Each entry
+ can include up to four pieces of info: The function name, a format string,
+ an argument list, and a color. But only a function name is required.
+
+ For a full example config, see config/custom-timeline-functions.cfg. It pulls
+ all the internal timeline functions into the config and allows you to edit
+ them.
+
+  Entry format:
+
+    function: format{fn_arg1}_{fn_arg2} fn_arg1 fn_arg2 ... [color=purple]
+
+  Required Arguments:
+
+    function: The symbol name for the function you want probed, this is the
+              minimum required for an entry, it will show up as the function
+              name with no arguments.
+
+        example: _cpu_up:
+
+  Optional Arguments:
+
+    format: The format to display the data on the timeline in. Use braces to
+            enclose the arg names.
+
+        example: CPU_ON[{cpu}]
+
+    color: The color of the entry block in the timeline. The default color is
+           transparent, so the entry shares the phase color. The color is an
+           html color string, either a word, or an RGB.
+
+        example: [color=#CC00CC]
+
+    arglist: A list of arguments from registers/stack addresses. See URL:
+             https://www.kernel.org/doc/Documentation/trace/kprobetrace.txt
+
+        example: cpu=%di:s32
+
+ Here is a full example entry. It displays cpu resume calls in the timeline
+ in orange. They will appear as CPU_ON[0], CPU_ON[1], etc.
+
+  [timeline_functions_x86_64]
+  _cpu_up: CPU_ON[{cpu}] cpu=%di:s32 [color=orange]
+
+
+Adding or Editing Dev Mode Timeline Source Functions
+____________________________________________________
+
+ In dev mode, the tool uses an array of function names to monitor source
+ execution within the timeline entries.
+
+ The function calls are displayed inside the main device/call blocks in the
+ timeline. However, if a function call is not within a main timeline event,
+ it will spawn an entirely new event named after the caller's kernel thread.
+ These asynchronous kernel threads will populate in a separate section
+ beneath the main device/call section.
+
+ The tool has a set of hard coded calls which focus on the most common use
+ cases: msleep, udelay, schedule_timeout, mutex_lock_slowpath, etc. These are
+ the functions that add a hardcoded time delay to the suspend/resume path.
+ The tool also includes some common functions native to important
+ subsystems: ata, i915, and ACPI, etc.
+
+ It is possible to add new function calls to the dev timeline by adding them
+ to the config. It's also possible to copy the internal dev timeline
+ functions into the config so that you can override and edit them. Place them
+ in the dev_timeline_functions_ARCH section with the name of your architecture
+ appended. i.e. for x86_64: [dev_timeline_functions_x86_64]
+
+ Use the override-dev-timeline-functions option if you only want to use your
+ custom calls, or leave it false to append them to the internal ones.
+
+ The format is the same as the timeline_functions_x86_64 section. It's a
+ list of functions (set using kprobes) which use both symbol data and function
+ arg data. The args are pulled directly from the stack using this
+ architecture's registers and stack formatting. Each entry can include up
+ to four pieces of info: The function name, a format string, an argument list,
+ and a color. But only the function name is required.
+
+ For a full example config, see config/custom-timeline-functions.cfg. It pulls
+ all the internal dev timeline functions into the config and allows you to edit
+ them.
+
+ Here is a full example entry. It displays the ATA port reset calls as
+ ataN_port_reset in the timeline. This is where most of the SATA disk resume
+ time goes, so it can be helpful to see the low level call.
+
+  [dev_timeline_functions_x86_64]
+  ata_eh_recover: ata{port}_port_reset port=+36(%di):s32 [color=#CC00CC]
+
+
+Verifying your custom functions
+_______________________________
+
+ Once you have a set of functions (kprobes) defined, it can be useful to
+ perform a quick check to see if you formatted them correctly and if the system
+ actually supports them. To do this, run the tool with your config file
+ and the -status option. The tool will go through all the kprobes (both
+ custom and internal if you haven't overridden them) and actually attempts
+ to set them in ftrace. It will then print out success or fail for you.
+
+ Note that kprobes which don't actually exist in the kernel won't stop the
+ tool, they just wont show up.
+
+ For example:
+
+ sudo ./sleepgraph.py -config config/custom-timeline-functions.cfg -status
+ Checking this system (myhostname)...
+    have root access: YES
+    is sysfs mounted: YES
+    is "mem" a valid power mode: YES
+    is ftrace supported: YES
+    are kprobes supported: YES
+    timeline data source: FTRACE (all trace events found)
+    is rtcwake supported: YES
+    verifying timeline kprobes work:
+         _cpu_down: YES
+         _cpu_up: YES
+         acpi_pm_finish: YES
+         acpi_pm_prepare: YES
+         freeze_kernel_threads: YES
+         freeze_processes: YES
+         sys_sync: YES
+         thaw_processes: YES
+    verifying dev kprobes work:
+         __const_udelay: YES
+         __mutex_lock_slowpath: YES
+         acpi_os_stall: YES
+         acpi_ps_parse_aml: YES
+         intel_opregion_init: NO
+         intel_opregion_register: NO
+         intel_opregion_setup: NO
+         msleep: YES

+ sleepgraph.py on it.
+
+ Here are the steps:
+
+ [download and install the tool on the device]
+

+
+ [retrieve the data from the device]
+
+	# I find that you have to actually kill the adb process and

+.TH BOOTGRAPH 8
+.SH NAME
+bootgraph \- Kernel boot timing analysis
+.SH SYNOPSIS
+.ft B
+.B bootgraph
+.RB [ OPTIONS ]
+.RB [ COMMAND ]
+.SH DESCRIPTION
+\fBbootgraph \fP reads the dmesg log from kernel boot and
+creates an html representation of the initcall timeline. It graphs
+every module init call found, through both kernel and user modes. The
+timeline is split into two phases: kernel mode & user mode. kernel mode
+represents a single process run on a single cpu with serial init calls.
+Once user mode begins, the init process is called, and the init calls
+start working in parallel.
+.PP
+If no specific command is given, the tool reads the current dmesg log and
+outputs a new timeline.
+.PP
+The tool can also augment the timeline with ftrace data on custom target
+functions as well as full trace callgraphs.
+.PP
+Generates output files in subdirectory: boot-yymmdd-HHMMSS
+   html timeline   :     <hostname>_boot.html
+   raw dmesg file  :     <hostname>_boot_dmesg.txt
+   raw ftrace file :     <hostname>_boot_ftrace.txt
+.SH OPTIONS
+.TP
+\fB-h\fR
+Print this help text
+.TP
+\fB-v\fR
+Print the current tool version
+.TP
+\fB-addlogs\fR
+Add the dmesg log to the html output. It will be viewable by
+clicking a button in the timeline.
+.TP
+\fB-result \fIfile\fR
+Export a results table to a text file for parsing.
+.TP
+\fB-o \fIname\fR
+Overrides the output subdirectory name when running a new test.
+Use {date}, {time}, {hostname} for current values.
+.sp
+e.g. boot-{hostname}-{date}-{time}
+.SS "advanced"
+.TP
+\fB-f or -callgraph\fR
+Use ftrace to create initcall callgraphs (default: disabled). If -func
+is not used there will be one callgraph per initcall. This can produce
+very large outputs, i.e. 10MB - 100MB.
+.TP
+\fB-fstat\fR
+Use ftrace to add function detail (default: disabled)
+.TP
+\fB-maxdepth \fIlevel\fR
+limit the callgraph trace depth to \fIlevel\fR (default: 2). This is
+the best way to limit the output size when using -callgraph.
+.TP
+\fB-mincg \fIt\fR
+Discard all callgraphs shorter than \fIt\fR milliseconds (default: 0=all).
+This reduces the html file size as there can be many tiny callgraphs
+which are barely visible in the timeline.
+The value is a float: e.g. 0.001 represents 1 us.
+.TP
+\fB-cgfilter \fI"func1,func2,..."\fR
+Reduce callgraph output in the timeline by limiting it to a list of calls. The
+argument can be a single function name or a comma delimited list.
+(default: none)
+.TP
+\fB-cgskip \fIfile\fR
+Reduce callgraph output in the timeline by skipping over uninteresting
+functions in the trace, e.g. printk or console_unlock. The functions listed
+in this file will show up as empty leaves in the callgraph with only the start/end
+times displayed.
+(default: none)
+.TP
+\fB-timeprec \fIn\fR
+Number of significant digits in timestamps (0:S, 3:ms, [6:us])
+.TP
+\fB-expandcg\fR
+pre-expand the callgraph data in the html output (default: disabled)
+.TP
+\fB-func \fI"func1,func2,..."\fR
+Instead of tracing each initcall, trace a custom list of functions (default: do_one_initcall)
+.TP
+\fB-reboot\fR
+Reboot the machine and generate a new timeline automatically. Works in 4 steps.
+  1. updates grub with the required kernel parameters
+  2. installs a cron job which re-runs the tool after reboot
+  3. reboots the system
+  4. after startup, extracts the data and generates the timeline
+.TP
+\fB-manual\fR
+Show the requirements to generate a new timeline manually. Requires 3 steps.
+  1. append the string to the kernel command line via your native boot manager.
+  2. reboot the system
+  3. after startup, re-run the tool with the same arguments and no command
+
+.SH COMMANDS
+.SS "rebuild"
+.TP
+\fB-dmesg \fIfile\fR
+Create HTML output from an existing dmesg file.
+.TP
+\fB-ftrace \fIfile\fR
+Create HTML output from an existing ftrace file (used with -dmesg).
+.SS "other"
+.TP
+\fB-flistall\fR
+Print all ftrace functions capable of being captured. These are all the
+possible values you can add to trace via the -func argument.
+.TP
+\fB-sysinfo\fR
+Print out system info extracted from BIOS. Reads /dev/mem directly instead of going through dmidecode.
+

+.TH SLEEPGRAPH 8
+.SH NAME
+sleepgraph \- Suspend/Resume timing analysis
+.SH SYNOPSIS
+.ft B
+.B sleepgraph
+.RB [ OPTIONS ]
+.RB [ COMMAND ]
+.SH DESCRIPTION
+\fBsleepgraph \fP is designed to assist kernel and OS developers
+in optimizing their linux stack's suspend/resume time. Using a kernel
+image built with a few extra options enabled, the tool will execute a
+suspend and capture dmesg and ftrace data until resume is complete.
+This data is transformed into a device timeline and an optional
+callgraph to give a detailed view of which devices/subsystems are
+taking the most time in suspend/resume.
+.PP
+If no specific command is given, the default behavior is to initiate
+a suspend/resume.
+.PP
+Generates output files in subdirectory: suspend-yymmdd-HHMMSS
+   html timeline   :     <hostname>_<mode>.html
+   raw dmesg file  :     <hostname>_<mode>_dmesg.txt
+   raw ftrace file :     <hostname>_<mode>_ftrace.txt
+.SH OPTIONS
+.TP
+\fB-h\fR
+Print the help text.
+.TP
+\fB-v\fR
+Print the current tool version.
+.TP
+\fB-verbose\fR
+Print extra information during execution and analysis.
+.TP
+\fB-config \fIfile\fR
+Pull arguments and config options from a file.
+.TP
+\fB-m \fImode\fR
+Mode to initiate for suspend e.g. standby, freeze, mem (default: mem).
+.TP
+\fB-o \fIname\fR
+Overrides the output subdirectory name when running a new test.
+Use {date}, {time}, {hostname} for current values.
+.sp
+e.g. suspend-{hostname}-{date}-{time}
+.TP
+\fB-rtcwake \fIt\fR | off
+Use rtcwake to autoresume after \fIt\fR seconds (default: 15). Set t to "off" to
+disable rtcwake and require a user keypress to resume.
+.TP
+\fB-addlogs\fR
+Add the dmesg and ftrace logs to the html output. They will be viewable by
+clicking buttons in the timeline.
+.TP
+\fB-noturbostat\fR
+By default, if turbostat is found and the requested mode is freeze, sleepgraph
+will execute the suspend via turbostat and collect data in the timeline log.
+This option disables the use of turbostat.
+.TP
+\fB-result \fIfile\fR
+Export a results table to a text file for parsing.
+.TP
+\fB-sync\fR
+Sync the filesystems before starting the test. This reduces the size of
+the sys_sync call which happens in the suspend_prepare phase.
+.TP
+\fB-rs \fIenable/disable\fR
+During test, enable/disable runtime suspend for all devices. The test is delayed
+by 5 seconds to allow runtime suspend changes to occur. The settings are restored
+after the test is complete.
+.TP
+\fB-display \fIon/off/standby/suspend\fR
+Switch the display to the requested mode for the test using the xset command.
+This helps maintain the consistency of test data for better comparison.
+.TP
+\fB-wifi\fR
+If a wifi connection is available, check that it reconnects after resume. Include
+the reconnect time in the total resume time calculation and treat wifi timeouts
+as resume failures.
+.TP
+\fB-wifitrace\fR
+Trace through the wifi reconnect time and include it in the timeline.
+
+.SS "advanced"
+.TP
+\fB-gzip\fR
+Gzip the trace and dmesg logs to save space. The tool can also read in gzipped
+logs for processing.
+.TP
+\fB-cmd \fIstr\fR
+Run the timeline over a custom suspend command, e.g. pm-suspend. By default
+the tool forces suspend via /sys/power/state so this allows testing over
+an OS's official suspend method. The output file will change to
+hostname_command.html and will autodetect which suspend mode was triggered.
+.TP
+\fB-filter \fI"d1,d2,..."\fR
+Filter out all but these device callbacks. These strings can be device names
+or module names. e.g. 0000:00:02.0, ata5, i915, usb, etc.
+.TP
+\fB-mindev \fIt\fR
+Discard all device callbacks shorter than \fIt\fR milliseconds (default: 0.0).
+This reduces the html file size as there can be many tiny callbacks which are barely
+visible. The value is a float: e.g. 0.001 represents 1 us.
+.TP
+\fB-proc\fR
+Add usermode process info into the timeline (default: disabled).
+.TP
+\fB-dev\fR
+Add kernel source calls and threads to the timeline (default: disabled).
+.TP
+\fB-x2\fR
+Run two suspend/resumes back to back (default: disabled).
+.TP
+\fB-x2delay \fIt\fR
+Include \fIt\fR ms delay between multiple test runs (default: 0 ms).
+.TP
+\fB-predelay \fIt\fR
+Include \fIt\fR ms delay before 1st suspend (default: 0 ms).
+.TP
+\fB-postdelay \fIt\fR
+Include \fIt\fR ms delay after last resume (default: 0 ms).
+.TP
+\fB-multi \fIn d\fR
+Used for endurance testing. If \fIn\fR is entirely numeric, it's treated as a count:
+Execute \fIn\fR consecutive tests at \fId\fR second intervals.
+If \fIn\fR is an integer followed by a "d", "h", or "m", it's treated as a duration:
+Execute tests continuously over \fIn\fR days, hours, or minutes at \fId\fR second intervals.
+The outputs will be created in a new subdirectory, for count: suspend-{date}-{time}-xN,
+for duration: suspend-{date}-{time}-Nm. When the multitest run is done, the \fI-summary\fR
+command is called automatically to create summary html files for all the data (unless you
+use \fI-skiphtml\fR). \fI-skiphtml\fR will speed up the testing by not creating timelines
+or summary html files. You can then run the tool again at a later time with \fI-summary\fR
+and \fI-genhtml\fR to create the timelines.
+.TP
+\fB-maxfail \fIn\fR
+Abort a -multi run after \fIn\fR consecutive fails. 0 means never abort (default = 0).
+.TP
+\fB-skiphtml\fR
+Run the test and capture the trace logs, but skip the timeline generation.
+You can generate the html timelines later with \fI-dmesg\fR & \fI-ftrace\fR, or
+by running \fI-summary\fR and \fI-genhtml\fR.
+
+.SS "ftrace debug"
+.TP
+\fB-f\fR
+Use ftrace to create device callgraphs (default: disabled). This can produce
+very large outputs, i.e. 10MB - 100MB.
+.TP
+\fB-ftop\fR
+Use ftrace on the top level call: "suspend_devices_and_enter" only (default: disabled).
+This option implies -f and creates a single callgraph covering all of suspend/resume.
+.TP
+\fB-maxdepth \fIlevel\fR
+limit the callgraph trace depth to \fIlevel\fR (default: 0=all). This is
+the best way to limit the output size when using callgraphs via -f.
+.TP
+\fB-expandcg\fR
+pre-expand the callgraph data in the html output (default: disabled)
+.TP
+\fB-fadd \fIfile\fR
+Add functions to be graphed in the timeline from a list in a text file
+.TP
+\fB-mincg \fIt\fR
+Discard all callgraphs shorter than \fIt\fR milliseconds (default: 0.0).
+This reduces the html file size as there can be many tiny callgraphs
+which are barely visible in the timeline.
+The value is a float: e.g. 0.001 represents 1 us.
+.TP
+\fB-cgfilter \fI"func1,func2,..."\fR
+Reduce callgraph output in the timeline by limiting it certain devices. The
+argument can be a single device name or a comma delimited list.
+(default: none)
+.TP
+\fB-cgskip \fIfile\fR
+Reduce callgraph timeline size by skipping over uninteresting functions
+in the trace, e.g. printk or console_unlock. The functions listed
+in this file will show up as empty leaves in the callgraph with only the start/end
+times displayed. cgskip.txt is used automatically if found in the path, so
+use "off" to disable completely (default: cgskip.txt)
+.TP
+\fB-cgphase \fIp\fR
+Only show callgraph data for phase \fIp\fR (e.g. suspend_late).
+.TP
+\fB-cgtest \fIn\fR
+In an x2 run, only show callgraph data for test \fIn\fR (e.g. 0 or 1).
+.TP
+\fB-timeprec \fIn\fR
+Number of significant digits in timestamps (0:S, [3:ms], 6:us).
+.TP
+\fB-bufsize \fIN\fR
+Set trace buffer size to N kilo-bytes (default: all of free memory up to 3GB)
+
+.SH COMMANDS
+.TP
+\fB-summary \fIindir\fR
+Create a set of summary pages for all tests in \fIindir\fR recursively.
+Creates summary.html, summary-issues.html, and summary-devices.html in the current folder.
+summary.html is a table of tests with relevant info sorted by kernel/host/mode,
+and links to the test html files. It identifies the minimum, maximum, and median
+suspend and resume times for you with highlights and links in the header.
+summary-issues.html is a list of kernel issues found in dmesg from all the tests.
+summary-devices.html is a list of devices and times from all the tests.
+
+Use \fI-genhtml\fR to regenerate any tests with missing html.
+.TP
+\fB-genhtml\fR
+Used with \fI-summary\fR to regenerate any missing html timelines from their
+dmesg and ftrace logs. This will require a significant amount of time if there
+are thousands of tests.
+.TP
+\fB-modes\fR
+List available suspend modes.
+.TP
+\fB-status\fR
+Test to see if the system is able to run this tool. Use this along
+with any options you intend to use to see if they will work.
+.TP
+\fB-fpdt\fR
+Print out the contents of the ACPI Firmware Performance Data Table.
+.TP
+\fB-wificheck\fR
+Print out wifi status and connection details.
+.TP
+\fB-xon/-xoff/-xstandby/-xsuspend\fR
+Test xset by attempting to switch the display to the given mode. This
+is the same command which will be issued by \fB-display \fImode\fR.
+.TP
+\fB-xstat\fR
+Get the current DPMS display mode.
+.TP
+\fB-sysinfo\fR
+Print out system info extracted from BIOS. Reads /dev/mem directly instead of going through dmidecode.
+.TP
+\fB-devinfo\fR
+Print out the pm settings of all devices which support runtime suspend.
+.TP
+\fB-cmdinfo\fR
+Print out all the platform data collected from the system that makes it into the logs.
+.TP
+\fB-flist\fR
+Print the list of ftrace functions currently being captured. Functions
+that are not available as symbols in the current kernel are shown in red.
+By default, the tool traces a list of important suspend/resume functions
+in order to better fill out the timeline. If the user has added their own
+with -fadd they will also be checked.
+.TP
+\fB-flistall\fR
+Print all ftrace functions capable of being captured. These are all the
+possible values you can add to trace via the -fadd argument.
+.SS "rebuild"
+.TP
+\fB-ftrace \fIfile\fR
+Create HTML output from an existing ftrace file.
+.TP
+\fB-dmesg \fIfile\fR
+Create HTML output from an existing dmesg file.

+# Description:
+#	 This tool is designed to assist kernel and OS developers in optimizing
+#	 their linux stack's suspend/resume time. Using a kernel image built
+#	 with a few extra options enabled, the tool will execute a suspend and
+#	 will capture dmesg and ftrace data until resume is complete. This data
+#	 is transformed into a device timeline and a callgraph to give a quick
+#	 and detailed view of which devices and callbacks are taking the most
+#	 time in suspend/resume. The output is a single html file which can be
+#	 viewed in firefox or chrome.
+#
+#	 The following kernel build options are required:
+#		 CONFIG_DEVMEM=y
+#		 CONFIG_PM_DEBUG=y
+#		 CONFIG_PM_SLEEP_DEBUG=y
+#		 CONFIG_FTRACE=y
+#		 CONFIG_FUNCTION_TRACER=y
+#		 CONFIG_FUNCTION_GRAPH_TRACER=y
+#		 CONFIG_KPROBES=y
+#		 CONFIG_KPROBES_ON_FTRACE=y
+#
+#	 For kernel versions older than 3.15:
+#	 The following additional kernel parameters are required:
+#		 (e.g. in file /etc/default/grub)
+#		 GRUB_CMDLINE_LINUX_DEFAULT="... initcall_debug log_buf_len=16M ..."

+""" This utility can be used to debug and tune the performance of the
+intel_pstate driver. This utility can be used in two ways:
+- If there is Linux trace file with pstate_sample events enabled, then
+this utility can parse the trace file and generate performance plots.
+- If user has not specified a trace file as input via command line parameters,
+then this utility enables and collects trace data for a user specified interval
+and generates performance plots.
+
+Prerequisites:
+    Python version 2.7.x or higher
+    gnuplot 5.0 or higher
+    gnuplot-py 1.8 or higher
+    (Most of the distributions have these required packages. They may be called
+     gnuplot-py, phython-gnuplot or phython3-gnuplot, gnuplot-nox, ... )
+
+    HWP (Hardware P-States are disabled)
+    Kernel config for Linux trace is enabled
+
+    see print_help(): for Usage and Output details

+.TH TURBOSTAT 8
+.SH NAME
+turbostat \- Report processor frequency and idle statistics
+.SH SYNOPSIS
+.ft B
+.B turbostat
+.RB [ Options ]
+.RB command
+.br
+.B turbostat
+.RB [ Options ]
+.RB [ "\--interval seconds" ]
+.SH DESCRIPTION
+\fBturbostat \fP reports processor topology, frequency,
+idle power-state statistics, temperature and power on X86 processors.
+There are two ways to invoke turbostat.
+The first method is to supply a
+\fBcommand\fP, which is forked and statistics are printed
+in one-shot upon its completion.
+The second method is to omit the command,
+and turbostat displays statistics every 5 seconds interval.
+The 5-second interval can be changed using the --interval option.
+.PP
+Some information is not available on older processors.
+.SS Options
+Options can be specified with a single or double '-', and only as much of the option
+name as necessary to disambiguate it from others is necessary.  Note that options are case-sensitive.
+.PP
+\fB--add attributes\fP add column with counter having specified 'attributes'.  The 'location' attribute is required, all others are optional.
+.nf
+	location: {\fBmsrDDD\fP | \fBmsr0xXXX\fP | \fB/sys/path...\fP}
+		msrDDD is a decimal offset, eg. msr16
+		msr0xXXX is a hex offset, eg. msr0x10
+		/sys/path... is an absolute path to a sysfs attribute
+
+	scope: {\fBcpu\fP | \fBcore\fP | \fBpackage\fP}
+		sample and print the counter for every cpu, core, or package.
+		default: cpu
+
+	size: {\fBu32\fP | \fBu64\fP }
+		MSRs are read as 64-bits, u32 truncates the displayed value to 32-bits.
+		default: u64
+
+	format: {\fBraw\fP | \fBdelta\fP | \fBpercent\fP}
+		'raw' shows the MSR contents in hex.
+		'delta' shows the difference in values during the measurement interval.
+		'percent' shows the delta as a percentage of the cycles elapsed.
+		default: delta
+
+	name: "name_string"
+		Any string that does not match a key-word above is used
+		as the column header.
+.fi
+.PP
+\fB--cpu cpu-set\fP limit output to system summary plus the specified cpu-set.  If cpu-set is the string "core", then the system summary plus the first CPU in each core are printed -- eg. subsequent HT siblings are not printed.  Or if cpu-set is the string "package", then the system summary plus the first CPU in each package is printed.  Otherwise, the system summary plus the specified set of CPUs are printed.  The cpu-set is ordered from low to high, comma delimited with ".." and "-" permitted to denote a range. eg. 1,2,8,14..17,21-44
+.PP
+\fB--hide column\fP do not show the specified built-in columns.  May be invoked multiple times, or with a comma-separated list of column names.
+.PP
+\fB--enable column\fP show the specified built-in columns, which are otherwise disabled, by default.  Currently the only built-in counters disabled by default are "usec", "Time_Of_Day_Seconds", "APIC" and "X2APIC".
+The column name "all" can be used to enable all disabled-by-default built-in counters.
+.PP
+\fB--show column\fP show only the specified built-in columns.  May be invoked multiple times, or with a comma-separated list of column names.
+.PP
+\fB--show CATEGORY --hide CATEGORY\fP  Show and hide also accept a single CATEGORY of columns: "all", "topology", "idle", "frequency", "power", "sysfs", "other".
+.PP
+\fB--Dump\fP displays the raw counter values.
+.PP
+\fB--quiet\fP Do not decode and print the system configuration header information.
+.PP
+\fB--interval seconds\fP overrides the default 5.0 second measurement interval.
+.PP
+\fB--num_iterations num\fP number of the measurement iterations.
+.PP
+\fB--out output_file\fP turbostat output is written to the specified output_file.
+The file is truncated if it already exists, and it is created if it does not exist.
+.PP
+\fB--help\fP displays usage for the most common parameters.
+.PP
+\fB--Joules\fP displays energy in Joules, rather than dividing Joules by time to print power in Watts.
+.PP
+\fB--list\fP display column header names available for use by --show and --hide, then exit.
+.PP
+\fB--Summary\fP limits output to a 1-line System Summary for each interval.
+.PP
+\fB--TCC temperature\fP sets the Thermal Control Circuit temperature for systems which do not export that value.  This is used for making sense of the Digital Thermal Sensor outputs, as they return degrees Celsius below the TCC activation temperature.
+.PP
+\fB--version\fP displays the version.
+.PP
+The \fBcommand\fP parameter forks \fBcommand\fP, and upon its exit,
+displays the statistics gathered since it was forked.
+.PP
+.SH ROW DESCRIPTIONS
+The system configuration dump (if --quiet is not used) is followed by statistics.  The first row of the statistics labels the content of each column (below).  The second row of statistics is the system summary line.  The system summary line has a '-' in the columns for the Package, Core, and CPU.  The contents of the system summary line depends on the type of column.  Columns that count items (eg. IRQ) show the sum across all CPUs in the system.  Columns that show a percentage show the average across all CPUs in the system.  Columns that dump raw MSR values simply show 0 in the summary.  After the system summary row, each row describes a specific Package/Core/CPU.  Note that if the --cpu parameter is used to limit which specific CPUs are displayed, turbostat will still collect statistics for all CPUs in the system and will still show the system summary for all CPUs in the system.
+.SH COLUMN DESCRIPTIONS
+.PP
+\fBusec\fP For each CPU, the number of microseconds elapsed during counter collection, including thread migration -- if any.  This counter is disabled by default, and is enabled with "--enable usec", or --debug.  On the summary row, usec refers to the total elapsed time to collect the counters on all cpus.
+.PP
+\fBTime_Of_Day_Seconds\fP For each CPU, the gettimeofday(2) value (seconds.subsec since Epoch) when the counters ending the measurement interval were collected.  This column is disabled by default, and can be enabled with "--enable Time_Of_Day_Seconds" or "--debug".  On the summary row, Time_Of_Day_Seconds refers to the timestamp following collection of counters on the last CPU.
+.PP
+\fBCore\fP processor core number.  Note that multiple CPUs per core indicate support for Intel(R) Hyper-Threading Technology (HT).
+.PP
+\fBCPU\fP Linux CPU (logical processor) number.  Yes, it is okay that on many systems the CPUs are not listed in numerical order -- for efficiency reasons, turbostat runs in topology order, so HT siblings appear together.
+.PP
+\fBPackage\fP processor package number -- not present on systems with a single processor package.
+.PP
+\fBAvg_MHz\fP number of cycles executed divided by time elapsed.  Note that this includes idle-time when 0 instructions are executed.
+.PP
+\fBBusy%\fP percent of the measurement interval that the CPU executes instructions, aka. % of time in "C0" state.
+.PP
+\fBBzy_MHz\fP average clock rate while the CPU was not idle (ie. in "c0" state).
+.PP
+\fBTSC_MHz\fP average MHz that the TSC ran during the entire interval.
+.PP
+\fBIRQ\fP The number of interrupts serviced by that CPU during the measurement interval.  The system total line is the sum of interrupts serviced across all CPUs.  turbostat parses /proc/interrupts to generate this summary.
+.PP
+\fBSMI\fP The number of System Management Interrupts  serviced CPU during the measurement interval.  While this counter is actually per-CPU, SMI are triggered on all processors, so the number should be the same for all CPUs.
+.PP
+\fBC1, C2, C3...\fP The number times Linux requested the C1, C2, C3 idle state during the measurement interval.  The system summary line shows the sum for all CPUs.  These are C-state names as exported in /sys/devices/system/cpu/cpu*/cpuidle/state*/name.  While their names are generic, their attributes are processor specific. They the system description section of output shows what MWAIT sub-states they are mapped to on each system.
+.PP
+\fBC1%, C2%, C3%\fP The residency percentage that Linux requested C1, C2, C3....  The system summary is the average of all CPUs in the system.  Note that these are software, reflecting what was requested.  The hardware counters reflect what was actually achieved.
+.PP
+\fBCPU%c1, CPU%c3, CPU%c6, CPU%c7\fP show the percentage residency in hardware core idle states.  These numbers are from hardware residency counters.
+.PP
+\fBCoreTmp\fP Degrees Celsius reported by the per-core Digital Thermal Sensor.
+.PP
+\fBPkgTmp\fP Degrees Celsius reported by the per-package Package Thermal Monitor.
+.PP
+\fBGFX%rc6\fP The percentage of time the GPU is in the "render C6" state, rc6, during the measurement interval. From /sys/class/drm/card0/power/rc6_residency_ms.
+.PP
+\fBGFXMHz\fP Instantaneous snapshot of what sysfs presents at the end of the measurement interval. From /sys/class/graphics/fb0/device/drm/card0/gt_cur_freq_mhz.
+.PP
+\fBPkg%pc2, Pkg%pc3, Pkg%pc6, Pkg%pc7\fP percentage residency in hardware package idle states.  These numbers are from hardware residency counters.
+.PP
+\fBPkgWatt\fP Watts consumed by the whole package.
+.PP
+\fBCorWatt\fP Watts consumed by the core part of the package.
+.PP
+\fBGFXWatt\fP Watts consumed by the Graphics part of the package -- available only on client processors.
+.PP
+\fBRAMWatt\fP Watts consumed by the DRAM DIMMS -- available only on server processors.
+.PP
+\fBPKG_%\fP percent of the interval that RAPL throttling was active on the Package.  Note that the system summary is the sum of the package throttling time, and thus may be higher than 100% on a multi-package system.  Note that the meaning of this field is model specific.  For example, some hardware increments this counter when RAPL responds to thermal limits, but does not increment this counter when RAPL responds to power limits.  Comparing PkgWatt and PkgTmp to system limits is necessary.
+.PP
+\fBRAM_%\fP percent of the interval that RAPL throttling was active on DRAM.
+.PP
+\fBUncMHz\fP uncore MHz, instantaneous sample.
+.SH TOO MUCH INFORMATION EXAMPLE
+By default, turbostat dumps all possible information -- a system configuration header, followed by columns for all counters.
+This is ideal for remote debugging, use the "--out" option to save everything to a text file, and get that file to the expert helping you debug.
+.PP
+When you are not interested in all that information, and there are several ways to see only what you want.  First the "--quiet" option will skip the configuration information, and turbostat will show only the counter columns.  Second, you can reduce the columns with the "--hide" and "--show" options.  If you use the "--show" option, then turbostat will show only the columns you list.  If you use the "--hide" option, turbostat will show all columns, except the ones you list.
+.PP
+To find out what columns are available for --show and --hide, the "--list" option is available.  Usually, the CATEGORY names above are used to refer to groups of counters.  Also, for convenience, the special string "sysfs" can be used to refer to all of the sysfs C-state counters at once:
+.PP

+.SH ONE SHOT COMMAND EXAMPLE
+If turbostat is invoked with a command, it will fork that command
+and output the statistics gathered after the command exits.
+In this case, turbostat output goes to stderr, by default.
+Output can instead be saved to a file using the --out option.
+In this example, the "sleep 10" command is forked, and turbostat waits for it to complete before saving all statistics into "ts.out".  Note that "sleep 10" is not part of turbostat, but is simply an example of a command that turbostat can fork.  The "ts.out" file is what you want to edit in a very wide window, paste into a spreadsheet, or attach to a bugzilla entry.
+
+.nf
+[root@hsw]# ./turbostat -o ts.out sleep 10
+[root@hsw]#
+.fi
+
+.SH PERIODIC INTERVAL EXAMPLE
+Without a command to fork, turbostat displays statistics ever 5 seconds.
+Periodic output goes to stdout, by default, unless --out is used to specify an output file.
+The 5-second interval can be changed with the "-i sec" option.
+.nf

+This example also shows the use of the --show option to show only the desired columns.
+
+.SH SYSTEM CONFIGURATION INFORMATION EXAMPLE
+
+By default, turbostat always dumps system configuration information
+before taking measurements.  In the example above, "--quiet" is used
+to suppress that output.  Here is an example of the configuration information:

+The \fBmax efficiency\fP frequency, a.k.a. Low Frequency Mode, is the frequency
+available at the minimum package voltage.  The \fBTSC frequency\fP is the base
+frequency of the processor -- this should match the brand string
+in /proc/cpuinfo.  This base frequency
+should be sustainable on all CPUs indefinitely, given nominal power and cooling.
+The remaining rows show what maximum turbo frequency is possible
+depending on the number of idle cores.  Note that not all information is
+available on all processors.
+.SH ADD COUNTER EXAMPLE
+Here we limit turbostat to showing just the CPU number for cpu0 - cpu3.
+We add a counter showing the 32-bit raw value of MSR 0x199 (MSR_IA32_PERF_CTL),
+labeling it with the column header, "PRF_CTRL", and display it only once,
+afte the conclusion of a 0.1 second sleep.
+.nf
+sudo ./turbostat --quiet --cpu 0-3 --show CPU --add msr0x199,u32,raw,PRF_CTRL sleep .1
+0.101604 sec
+CPU	  PRF_CTRL
+-	0x00000000
+0	0x00000c00

+2	0x00000a00

+
+.SH INPUT
+
+For interval-mode, turbostat will immediately end the current interval
+when it sees a newline on standard input.
+turbostat will then start the next interval.
+Control-C will be send a SIGINT to turbostat,
+which will immediately abort the program with no further processing.
+.SH SIGNALS
+
+SIGINT will interrupt interval-mode.
+The end-of-interval data will be collected and displayed before turbostat exits.
+
+SIGUSR1 will end current interval,
+end-of-interval data will be collected and displayed before turbostat
+starts a new interval.
+.SH NOTES
+
+.B "turbostat "
+must be run as root.
+Alternatively, non-root users can be enabled to run turbostat this way:
+
+# setcap cap_sys_admin,cap_sys_rawio,cap_sys_nice=+ep path/to/turbostat
+
+# chmod +r /dev/cpu/*/msr
+
+# chmod +r /dev/cpu_dma_latency
+
+.B "turbostat "
+reads hardware counters, but doesn't write them.
+So it will not interfere with the OS or other programs, including
+multiple invocations of itself.
+
+\fBturbostat \fP
+may work poorly on Linux-2.6.20 through 2.6.29,
+as \fBacpi-cpufreq \fPperiodically cleared the APERF and MPERF MSRs
+in those kernels.
+
+AVG_MHz = APERF_delta/measurement_interval.  This is the actual
+number of elapsed cycles divided by the entire sample interval --
+including idle time.  Note that this calculation is resilient
+to systems lacking a non-stop TSC.
+
+TSC_MHz = TSC_delta/measurement_interval.
+On a system with an invariant TSC, this value will be constant
+and will closely match the base frequency value shown
+in the brand string in /proc/cpuinfo.  On a system where
+the TSC stops in idle, TSC_MHz will drop
+below the processor's base frequency.
+
+Busy% = MPERF_delta/TSC_delta
+
+Bzy_MHz = TSC_delta/APERF_delta/MPERF_delta/measurement_interval
+
+Note that these calculations depend on TSC_delta, so they
+are not reliable during intervals when TSC_MHz is not running at the base frequency.
+
+Turbostat data collection is not atomic.
+Extremely short measurement intervals (much less than 1 second),
+or system activity that prevents turbostat from being able
+to run on all CPUS to quickly collect data, will result in
+inconsistent results.
+
+The APERF, MPERF MSRs are defined to count non-halted cycles.
+Although it is not guaranteed by the architecture, turbostat assumes
+that they count at TSC rate, which is true on all processors tested to date.

+.SH DESCRIPTION
+\fBx86_energy_perf_policy\fP
+displays and updates energy-performance policy settings specific to
+Intel Architecture Processors.  Settings are accessed via Model Specific Register (MSR)
+updates, no matter if the Linux cpufreq sub-system is enabled or not.
+
+Policy in MSR_IA32_ENERGY_PERF_BIAS (EPB)
+may affect a wide range of hardware decisions,
+such as how aggressively the hardware enters and exits CPU idle states (C-states)
+and Processor Performance States (P-states).
+This policy hint does not replace explicit OS C-state and P-state selection.
+Rather, it tells the hardware how aggressively to implement those selections.
+Further, it allows the OS to influence energy/performance trade-offs where there
+is no software interface, such as in the opportunistic "turbo-mode" P-state range.
+Note that MSR_IA32_ENERGY_PERF_BIAS is defined per CPU,
+but some implementations
+share a single MSR among all CPUs in each processor package.
+On those systems, a write to EPB on one processor will
+be visible, and will have an effect, on all CPUs
+in the same processor package.
+
+Hardware P-States (HWP) are effectively an expansion of hardware
+P-state control from the opportunistic turbo-mode P-state range
+to include the entire range of available P-states.
+On Broadwell Xeon, the initial HWP implementation, EPB influenced HWP.
+That influence was removed in subsequent generations,
+where it was moved to the
+Energy_Performance_Preference (EPP) field in
+a pair of dedicated MSRs -- MSR_IA32_HWP_REQUEST and MSR_IA32_HWP_REQUEST_PKG.
+
+EPP is the most commonly managed knob in HWP mode,
+but MSR_IA32_HWP_REQUEST also allows the user to specify
+minimum-frequency for Quality-of-Service,
+and maximum-frequency for power-capping.
+MSR_IA32_HWP_REQUEST is defined per-CPU.
+
+MSR_IA32_HWP_REQUEST_PKG has the same capability as MSR_IA32_HWP_REQUEST,
+but it can simultaneously set the default policy for all CPUs within a package.
+A bit in per-CPU MSR_IA32_HWP_REQUEST indicates whether it is
+over-ruled-by or exempt-from MSR_IA32_HWP_REQUEST_PKG.
+
+MSR_HWP_CAPABILITIES shows the default values for the fields
+in MSR_IA32_HWP_REQUEST.  It is displayed when no values
+are being written.
+
+.SS SCOPE OPTIONS
+.PP
+\fB-c, --cpu\fP Operate on the MSR_IA32_HWP_REQUEST for each CPU in a CPU-list.
+The CPU-list may be comma-separated CPU numbers, with dash for range
+or the string "all".  Eg. '--cpu 1,4,6-8' or '--cpu all'.
+When --cpu is used, \fB--hwp-use-pkg\fP is available, which specifies whether the per-cpu
+MSR_IA32_HWP_REQUEST should be over-ruled by MSR_IA32_HWP_REQUEST_PKG (1),
+or exempt from MSR_IA32_HWP_REQUEST_PKG (0).
+
+\fB-p, --pkg\fP Operate on the MSR_IA32_HWP_REQUEST_PKG for each package in the package-list.
+The list is a string of individual package numbers separated
+by commas, and or ranges of package numbers separated by a dash,
+or the string "all".
+For example '--pkg 1,3' or '--pkg all'
+
+.SS VALUE OPTIONS
+.PP
+.I normal | default
+Set a policy with a normal balance between performance and energy efficiency.
+The processor will tolerate minor performance compromise
+for potentially significant energy savings.
+This is a reasonable default for most desktops and servers.
+"default" is a synonym for "normal".
+.PP
+.I performance
+Set a policy for maximum performance,
+accepting no performance sacrifice for the benefit of energy efficiency.
+.PP
+.I balance-performance
+Set a policy with a high priority on performance,
+but allowing some performance loss to benefit energy efficiency.
+.PP
+.I balance-power
+Set a policy where the performance and power are balanced.
+This is the default.
+.PP
+.I power
+Set a policy where the processor can accept
+a measurable performance impact to maximize energy efficiency.
+
+.PP
+The following table shows the mapping from the value strings above to actual MSR values.
+This mapping is defined in the Linux-kernel header, msr-index.h.
+
+.nf
+VALUE STRING      	EPB	EPP
+performance       	0	0
+balance-performance	4	128
+normal, default		6	128
+balance-power	 	8	192
+power       		15	255
+.fi
+.PP
+For MSR_IA32_HWP_REQUEST performance fields
+(--hwp-min, --hwp-max, --hwp-desired), the value option
+is in units of 100 MHz, Eg. 12 signifies 1200 MHz.
+
+.SS FIELD OPTIONS
+\fB-a, --all value-string\fP Sets all EPB and EPP and HWP limit fields to the value associated with
+the value-string.  In addition, enables turbo-mode and HWP-mode, if they were previous disabled.
+Thus "--all normal" will set a system without cpufreq into a well known configuration.
+.PP
+\fB-B, --epb\fP set EPB per-core or per-package.
+See value strings in the table above.
+.PP
+\fB-d, --debug\fP debug increases verbosity.  By default
+x86_energy_perf_policy is silent for updates,
+and verbose for read-only mode.
+.PP
+\fB-P, --hwp-epp\fP set HWP.EPP per-core or per-package.
+See value strings in the table above.
+.PP
+\fB-m, --hwp-min\fP request HWP to not go below the specified core/bus ratio.
+The "default" is the value found in IA32_HWP_CAPABILITIES.min.
+.PP
+\fB-M, --hwp-max\fP request HWP not exceed a the specified core/bus ratio.
+The "default" is the value found in IA32_HWP_CAPABILITIES.max.
+.PP
+\fB-D, --hwp-desired\fP request HWP 'desired' frequency.
+The "normal" setting is 0, which
+corresponds to 'full autonomous' HWP control.
+Non-zero performance values request a specific performance
+level on this processor, specified in multiples of 100 MHz.
+.PP
+\fB-w, --hwp-window\fP specify integer number of microsec
+in the sliding window that HWP uses to maintain average frequency.
+This parameter is meaningful only when the "desired" field above is non-zero.
+Default is 0, allowing the HW to choose.
+.SH OTHER OPTIONS
+.PP
+\fB-f, --force\fP writes the specified values without bounds checking.
+.PP
+\fB-U, --hwp-use-pkg\fP (0 | 1), when used in conjunction with --cpu,
+indicates whether the per-CPU MSR_IA32_HWP_REQUEST should be overruled (1)
+or exempt (0) from per-Package MSR_IA32_HWP_REQUEST_PKG settings.
+The default is exempt.
+.PP
+\fB-H, --hwp-enable\fP enable HardWare-P-state (HWP) mode.  Once enabled, system RESET is required to disable HWP mode.
+.PP
+\fB-t, --turbo-enable\fP enable (1) or disable (0) turbo mode.
+.PP
+\fB-v, --version\fP print version and exit.
+.PP
+If no request to change policy is made,
+the default behavior is to read
+and display the current system state,
+including the default capabilities.
+.SH WARNING
+.PP
+This utility writes directly to Model Specific Registers.
+There is no locking or coordination should this utility
+be used to modify HWP limit fields at the same time that
+intel_pstate's sysfs attributes access the same MSRs.
+.PP
+Note that --hwp-desired and --hwp-window are considered experimental.
+Future versions of Linux reserve the right to access these
+fields internally -- potentially conflicting with user-space access.
