============
Version 1 of the Activity Monitors architecture implements a counter group
of four fixed and architecturally defined 64-bit event counters.
- - CPU cycle counter: increments at the frequency of the CPU.
- - Constant counter: increments at the fixed frequency of the system
- clock.
- - Instructions retired: increments with every architecturally executed
- instruction.
- - Memory stall cycles: counts instruction dispatch stall cycles caused by
- misses in the last level cache within the clock domain.

+- Constant counter: increments at the fixed frequency of the system
+ clock.
+- Instructions retired: increments with every architecturally executed

+- Memory stall cycles: counts instruction dispatch stall cycles caused by

When in WFI or WFE these counters do not increment.
Firmware (code running at higher exception levels, e.g. arm-tf) support is
needed to:
- - Enable access for lower exception levels (EL2 and EL1) to the AMU
- registers.
- - Enable the counters. If not enabled these will read as 0.
- - Save/restore the counters before/after the CPU is being put/brought up
- from the 'off' power state.

When using kernels that have this feature enabled but boot with broken

The fixed counters of AMUv1 are accessible though the following system
register definitions:
- - SYS_AMEVCNTR0_CORE_EL0

Auxiliary platform specific counters can be accessed using
SYS_AMEVCNTR1_EL0(n), where n is a value between 0 and 15.
----------------
Currently, access from userspace to the AMU registers is disabled due to:
- - Security reasons: they might expose information about code executed in
- secure mode.
- - Purpose: AMU counters are intended for system management use.

Specifies the default pre-allocated buffer-size in kB for the
HD-audio driver. A larger buffer (e.g. 2048) is preferred
for systems using PulseAudio. The default 64 is chosen just
for compatibility reasons.
- On x86 systems, the default is zero as we need no preallocation.
+ On x86 systems, the default is 2048 as a reasonable value for
+ most of modern systems.
Note that the pre-allocation size can be changed dynamically
via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.

| SETUP |
------------------------------------------------------------------
- These packages are required to execute the scripts
+ Package Requirements
+ - runs with python2 or python3, choice is made by /usr/bin/python link
- python
- - python-requests
+ - python-configparser (for python2 sleepgraph)
+ - python-requests (for googlesheet.py)
+ - linux-tools-common (for turbostat usage in sleepgraph)
Ubuntu:
- sudo apt-get install python python-requests
+ sudo apt-get install python python-configparser python-requests linux-tools-common
Fedora:
- sudo dnf install python python-requests
+ sudo dnf install python python-configparser python-requests linux-tools-common
The tools can most easily be installed via git clone and make install
%> 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

.TP
-\fB-skiphtml\fR
-Run the test and capture the trace logs, but skip the timeline generation.
+\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.
.SS "advanced"
.TP
Include \fIt\fR ms delay after last resume (default: 0 ms).
.TP
\fB-multi \fIn d\fR
-Execute \fIn\fR consecutive tests at \fId\fR seconds intervals. The outputs will
-be created in a new subdirectory with a summary page: suspend-xN-{date}-{time}.
+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.

+\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
