33 \fB-verbose\fR
36 \fB-config \fIfile\fR
39 \fB-m \fImode\fR
40 Mode to initiate for suspend e.g. standby, freeze, mem (default: mem).
42 \fB-o \fIname\fR
46 e.g. suspend-{hostname}-{date}-{time}

52 \fB-addlogs\fR
56 \fB-result \fIfile\fR
59 \fB-sync\fR
63 \fB-rs \fIenable/disable\fR
64 During test, enable/disable runtime suspend for all devices. The test is delayed
65 by 5 seconds to allow runtime suspend changes to occur. The settings are restored
68 \fB-display \fIon/off\fR
72 \fB-skiphtml\fR
77 \fB-gzip\fR
81 \fB-cmd \fIstr\fR
82 Run the timeline over a custom suspend command, e.g. pm-suspend. By default
83 the tool forces suspend via /sys/power/state so this allows testing over
84 an OS's official suspend method. The output file will change to
85 hostname_command.html and will autodetect which suspend mode was triggered.

105 \fB-x2delay \fIt\fR
108 \fB-predelay \fIt\fR
109 Include \fIt\fR ms delay before 1st suspend (default: 0 ms).

116 be created in a new subdirectory with a summary page: suspend-xN-{date}-{time}.
120 \fB-f\fR
122 very large outputs, i.e. 10MB - 100MB.
124 \fB-maxdepth \fIlevel\fR
126 the best way to limit the output size when using callgraphs via -f.

162 Set trace buffer size to N kilo-bytes (default: all of free memory up to 3GB)
166 \fB-summary \fIindir\fR
169 suspend and resume values sorted by suspend mode, host, and kernel.
170 Includes test averages by mode and links to the test html files.
171 Use -genhtml to include tests with missing html.
173 \fB-modes\fR
174 List available suspend modes.

192 \fB-flist\fR
195 By default, the tool traces a list of important suspend/resume functions
197 with -fadd they will also be checked.
199 \fB-flistall\fR
201 possible values you can add to trace via the -fadd argument.
204 \fB-ftrace \fIfile\fR
207 \fB-dmesg \fIfile\fR
