[igt-dev] [PATCH i-g-t 02/11] trace.pl: Improve readability of graphical timeline representation
Tvrtko Ursulin

Mon Jul 9 13:19:55 UTC 2018
From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>
We add stripes for different stages of request execution so it is easier
to follow one context in the multi-colour mode.
Vertical stripe pattern indicates pipeline "blockages" - requests waiting
for dependencies before they are runnable.
Diagonal stripes indicate runnable requests waiting for GPU time.
Horizontal strips are requests executing on the GPU.
Also use this new multi-coloured mode from media-bench.pl.
v2:
John Harrison:
* Mention media-bench.pl in the commit.
* Fix HTML for single colour mode.
v3:
* Rebase.
* Apply stripes to legacy colouring as well.
v4:
John Harrison:
* Use per context colours for ctxsave and incomplete boxes.
* Clearer timeline legend.
