+.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.
+
+.SH EXAMPLES
+Create a timeline using the current dmesg log.
+.IP
+\f(CW$ bootgraph\fR
+.PP

+.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-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\fR
+Turn the display on or off for the test using the xset command. This helps
+maintain the consistecy of test data for better comparison.
+.TP
+\fB-skiphtml\fR
+Run the test and capture the trace logs, but skip the timeline generation.
+
+.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
+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-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 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 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.
+Use -genhtml to include tests with missing html.
+.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-battery\fR
+Print out battery status and current charge.
+.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-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.
