pm-graph: AnalyzeSuspend v5.0
- add -cgskip option to reduce callgraph output size - add -cgfilter option to focus on a list of devices - add -result option for exporting batch test results - removed all phoronix hooks, use -result to enable batch testing - change -usbtopo to -devinfo, now prints all devices - add -gzip option to read/write logs in gz format - add -bufsize option to manually control ftrace buffer size - add -sync option to run filesystem sync prior to test - add -display option to enable/disable the display prior to test - add -rs option to enable/disable runtime suspend on all devices for test - add installed config files to search path - add kernel error/warning links into the timeline - fix callgraph trace to better handle interrupts - include command string and kernel params in timeline output header Signed-off-by: Todd Brandt <todd.e.brandt@linux.intel.com> Signed-off-by: Rafael J.
