igt/scripts: trace.pl to parse the i915 tracepoints
Given a log file created via perf with some interesting trace
events enabled, this tool can generate the timeline graph of
requests getting queued, their dependencies resolved, sent to
the GPU for executing and finally completed.
This can be useful when analyzing certain classes of performance
issues. More help is available in the tool itself.
The tool will also calculate some overall per engine statistics,
like total time engine was idle and similar.
v2:
* Address missing git add.
* Make html output optional (--html switch) and by default
just output aggregated per engine stats to stdout.
v3:
* Added --trace option which invokes perf with the correct
options automatically.
* Added --avg-delay-stats which prints averages for things
like waiting on ready, waiting on GPU and context save
duration.
* Fix warnings when no waits on an engine.
* Correct help text.
v4:
* Add --squash-ctx-id to substract engine id from ctx id
when parsing to make it easier to identify which context
is which with new i915 ctx id allocation scheme.
* Reconstruct request_out events where they are missing.
