.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 up to the start
of the init process.
.PP
If no specific command is given, the tool reads the current dmesg log and
outputs bootgraph.html.
.PP
The tool can also augment the timeline with ftrace data on custom target
functions as well as full trace callgraphs.
.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-o \fIfile\fR
Override the HTML output filename (default: bootgraph.html)
.SS "Ftrace Debug"
.TP
\fB-f\fR
Use ftrace to add function detail (default: disabled)
.TP
\fB-callgraph\fR
Use ftrace to create initcall callgraphs (default: disabled). If -filter
is not used there will be one callgraph per initcall. This can produce
very large outputs, i.e. 10MB - 100MB.
.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.

.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 \fIsubdir\fR
Override the output subdirectory. 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.
.SS "Advanced"
.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
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}.
.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-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-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).
.SH COMMANDS
.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.
.TP
\fB-summary \fIindir\fR
Create a summary page of all tests in \fIindir\fR. Creates summary.html
in the current folder. The output page is a table of tests with
suspend and resume values sorted by suspend mode, host, and kernel.
Includes test averages by mode and links to the test html files.
.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-usbtopo\fR
Print out the current USB topology with power info.
.TP
\fB-usbauto\fR
Enable autosuspend for all connected USB devices.
.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.
