[igt-dev] [PATCH i-g-t v2 0/4] scripts/trace.pl: Re-order calculations and fixups

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

The trace.pl script calculates a bunch of statistics. It also
re-generates some timestamp values to correct issues with the log
being processed. These operations were all mixed up together thus some
were done multiple times (with different results each time). Whereas
some stats were not being re-calculated after the underlying data had
changed and thus were not actually correct at the end. Also, the
ordering of some operations was non-deterministic due to being based
on internal Perl hash ordering.

These patches rationalise all of this processing to ensure that it all
happens in the correct order and in a consistent manner.

v2: Review feedback from Tvrtko Ursulin.

John Harrison (4):
  scripts/trace.pl: More hash key optimisations
  scripts/trace.pl: Sort order
  scripts/trace.pl: Calculate stats only after all munging
  scripts/trace.pl: Simplify 'end' & 'notify' generation
