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 | +------------------------------------------------------------------ + + These packages are required to execute the scripts + - python + - python-requests + + Ubuntu: + sudo apt-get install python python-requests + + Fedora: + sudo dnf install python python-requests + + 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 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.

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 + schedule_timeout: YES + schedule_timeout_uninterruptible: YES + usleep_range: YES + + +------------------------------------------------------------------ +| TESTING ON CONSUMER LINUX OPERATING SYSTEMS | +------------------------------------------------------------------ + +Android +_______ + + The easiest way to execute on an android device is to run the android.sh + script on the device, then pull the ftrace log back to the host and run + sleepgraph.py on it. + + Here are the steps: + + [download and install the tool on the device] + + host%> wget https://raw.githubusercontent.com/intel/pm-graph/master/tools/android.sh + host%> adb connect 192.168.1.6 + host%> adb root + # push the script to a writeable location + host%> adb push android.sh /sdcard/ + + [check whether the tool will run on your device] + + host%> adb shell + dev%> cd /sdcard + dev%> sh android.sh status + host : asus_t100 + kernel : 3.14.0-i386-dirty + modes : freeze mem + rtcwake : supported + ftrace : supported + trace events { + suspend_resume: found + device_pm_callback_end: found + device_pm_callback_start: found + } + # the above is what you see on a system that's properly patched + + [execute the suspend] + + # NOTE: The suspend will only work if the screen isn't timed out, + # so you have to press some keys first to wake it up b4 suspend) + dev%> sh android.sh suspend mem + ------------------------------------ + Suspend/Resume timing test initiated + ------------------------------------ + hostname : asus_t100 + kernel : 3.14.0-i386-dirty + mode : mem + ftrace out : /mnt/shell/emulated/0/ftrace.txt + dmesg out : /mnt/shell/emulated/0/dmesg.txt + log file : /mnt/shell/emulated/0/log.txt + ------------------------------------ + INITIALIZING FTRACE........DONE + STARTING FTRACE + SUSPEND START @ 21:24:02 (rtcwake in 10 seconds) + <adb connection will now terminate> + + [retrieve the data from the device] + + # I find that you have to actually kill the adb process and + # reconnect sometimes in order for the connection to work post-suspend + host%> adb connect 192.168.1.6 + # (required) get the ftrace data, this is the most important piece + host%> adb pull /sdcard/ftrace.txt + # (optional) get the dmesg data, this is for debugging + host%> adb pull /sdcard/dmesg.txt + # (optional) get the log, which just lists some test times for comparison + host%> adb pull /sdcard/log.txt + + [create an output html file using sleepgraph.py] + + host%> sleepgraph.py -ftrace ftrace.txt + + You should now have an output.html with the android data, enjoy!
