cpustates can now handle the lack of a start marker in three ways:
- try: If the start marker is present only the correct section of the trace
will be used, if its not the whole trace will be used.
- error: An error will be raised if the start marker is missing
- ignore: The markers are ignored and the whole trace is always used.
The timeout for the pulling the trace file after the run is being set
based on the time for which the trace was collected. For workloads with
short execution time, but large number of events, the resulting timeout
might be too short. To deal with this, do not let the timout be shorter
than 1 minute.
Depending on the kernel, sched_switch events may be formatted one of two
different ways in the text output. Previously, we've only handled the
"old" format. This commit updates the parser to handle the new format as
well.
- Compiled regular expressions in EVENT_PARSER_MAP now get handled
correctly.
- regex_body_parser now attemts to convert field values to ints,
bringing it inline with the default parser behavior.
- There is now a regex for sched_switch events.
