To: linux-pm; +Cc: todd.e.brandt, rjw, rafael.j.wysocki, Todd Brandt
- config file support added
- dev mode for monitoring kernel source calls and async kernel threads
- custom command support for executing a user cmd instead of suspend
- proc mode support for monitoring user processes with cpu exec data
- kprobe support for custom function tracing
- advanced callgraph support for function debug
- many bug fixes and formatting upgrades

3 siblings, 0 replies; 5+ messages in thread
From: Todd Brandt @ 2017-02-09 21:06 UTC (permalink / raw)
To: linux-pm; +Cc: todd.e.brandt, rjw, rafael.j.wysocki, Todd Brandt
- when running with sudo, change output dir back to SUDO_USER ownership
- replace all os.system/popen instances with subprocess.call/Popen
- graph pm device callbacks and async threads in separate sections
- remove kprobe config section and replaced it with timeline_functions
- added new kprobe config section for dev mode: dev_timeline_functions
- merge call loops in dev mode to create a single event with a count
- added hover text to all header entries to explain what they mean
- changed the -filter option to grep device driver/name for a string
- added new options for tuning the dev mode timeline/custom kprobes

From: Todd Brandt @ 2017-02-09 21:06 UTC (permalink / raw)
To: linux-pm; +Cc: todd.e.brandt, rjw, rafael.j.wysocki, Todd Brandt
- when running with sudo, change output dir back to SUDO_USER ownership
- replace all os.system/popen instances with subprocess.call/Popen
- graph pm device callbacks and async threads in separate sections
- remove kprobe config section and replaced it with timeline_functions
- added new kprobe config section for dev mode: dev_timeline_functions
- merge call loops in dev mode to create a single event with a count
- added hover text to all header entries to explain what they mean
- changed the -filter option to grep device driver/name for a string
- added new options for tuning the dev mode timeline/custom kprobes
