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: + %> sudo ./sleepgraph.py -config config/suspend-dev.cfg + + +Config File Options +___________________ + + [Settings] + + # Verbosity: print verbose messages (def: false) + verbose: false + + # Suspend Mode: e.g. standby, mem, freeze, disk (def: mem) + mode: mem + + # Output Directory Format: {hostname}, {date}, {time} give current values + output-dir: suspend-{hostname}-{date}-{time} + + # Automatic Wakeup: use rtcwake to wakeup after X seconds (def: infinity) + rtcwake: 15 + + # Add Logs: add the dmesg and ftrace log to the html output (def: false) + addlogs: false + + # Sus/Res Gap: insert a gap between sus & res in the timeline (def: false) + srgap: false + + # Custom Command: Command to execute in lieu of suspend (def: "") + command: echo mem > /sys/power/state + + # Proc mode: graph user processes and cpu usage in the timeline (def: false) + proc: false + + # Dev mode: graph source functions in the timeline (def: false) + dev: false + + # Suspend/Resume x2: run 2 suspend/resumes back to back (def: false) + x2: false + + # x2 Suspend Delay: time delay between the two test runs in ms (def: 0 ms) + x2delay: 0 + + # Pre Suspend Delay: nclude an N ms delay before (1st) suspend (def: 0 ms) + predelay: 0 + + # Post Resume Delay: include an N ms delay after (last) resume (def: 0 ms) + postdelay: 0 + + # Min Device Length: graph only dev callbacks longer than min (def: 0.001 ms) + mindev: 0.001 + + # Callgraph: gather ftrace callgraph data on all timeline events (def: false) + callgraph: false + + # Expand Callgraph: pre-expand the callgraph treeviews in html (def: false) + expandcg: false + + # Min Callgraph Length: show callgraphs only if longer than min (def: 1 ms) + mincg: 1 + + # Timestamp Precision: number of sig digits in timestamps (0:S, [3:ms], 6:us) + timeprec: 3 + + # Device Filter: show only devs whose name/driver includes one of these strings + devicefilter: _cpu_up,_cpu_down,i915,usb + + # Override default timeline entries: + # Do not use the internal default functions for timeline entries (def: false) + # Set this to true if you intend to only use the ones defined in the config + override-timeline-functions: true + + # Override default dev timeline entries: + # Do not use the internal default functions for dev timeline entries (def: false) + # Set this to true if you intend to only use the ones defined in the config + override-dev-timeline-functions: true + + # Call Loop Max Gap (dev mode only) + # merge loops of the same call if each is less than maxgap apart (def: 100us) + callloop-maxgap: 0.0001 + + # Call Loop Max Length (dev mode only) + # merge loops of the same call if each is less than maxlen in length (def: 5ms) + callloop-maxlen: 0.005 + +------------------------------------------------------------------ +| CUSTOM TIMELINE ENTRIES | +------------------------------------------------------------------ + +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.

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.

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.

To do this, run the tool with your config file + and the -status option.

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.

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 +.nf +sudo ./turbostat --show sysfs --quiet sleep 10 +10.003837 sec + C1 C1E C3 C6 C7s C1% C1E% C3% C6% C7s% + 4 21 2 2 459 0.14 0.82 0.00 0.00 98.93 + 1 17 2 2 130 0.00 0.02 0.00 0.00 99.80 + 0 0 0 0 31 0.00 0.00 0.00 0.00 99.95 + 2 1 0 0 52 1.14 6.49 0.00 0.00 92.21 + 1 2 0 0 52 0.00 0.08 0.00 0.00 99.86 + 0 0 0 0 71 0.00 0.00 0.00 0.00 99.89 + 0 0 0 0 25 0.00 0.00 0.00 0.00 99.96 + 0 0 0 0 74 0.00 0.00 0.00 0.00 99.94 + 0 1 0 0 24 0.00 0.00 0.00 0.00 99.84 +.fi +.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.

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 +1 0x00000800 +2 0x00000a00 +3 0x00000800 + +.fi + +.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 ./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 REFERENCES +Volume 3B: System Programming Guide" +https://www.intel.com/products/processor/manuals/ + +.SH FILES +.ta +.nf +/dev/cpu/*/msr +.fi + +.SH "SEE ALSO" +msr(4), vmstat(8) +.PP +.SH AUTHOR +.nf +Written by Len Brown <len.brown@intel.com> diff --git a/tools/power/x86/turbostat/turbostat.c b/tools/power/x86/turbostat/turbostat.c new file mode 100644 index 000000000..b113900d9 --- /dev/null +++ b/tools/power/x86/turbostat/turbostat.c @@ -0,0 +1,6757 @@ +// SPDX-License-Identifier: GPL-2.0-only +/* + * turbostat -- show CPU frequency and C-state residency + * on modern Intel and AMD processors. + * + * Copyright (c) 2022 Intel Corporation. + * Len Brown <len.brown@intel.com> + */ + +#define _GNU_SOURCE +#include MSRHEADER +#include INTEL_FAMILY_HEADER +#include <stdarg.h> +#include <stdio.h> +#include <err.h> +#include <unistd.h> +#include <sys/types.h> +#include <sys/wait.h> +#include <sys/stat.h> +#include <sys/select.h> +#include <sys/resource.h> +#include <fcntl.h> +#include <signal.h> +#include <sys/time.h> +#include <stdlib.h> +#include <getopt.h> +#include <dirent.h> +#include <string.h> +#include <ctype.h> +#include <sched.h> +#include <time.h> +#include <cpuid.h> +#include <sys/capability.h> +#include <errno.h> +#include <math.h> +#include <linux/perf_event.h> +#include <asm/unistd.h> +#include <stdbool.h> + +#define UNUSED(x) (void)(x) + +/* + * This list matches the column headers, except + * 1. built-in only, the sysfs counters are not here -- we learn of those at run-time + * 2.

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.
