Subject: [PATCH i-g-t 2/8] trace.pl: Improve readability of graphical timeline representation
Date: Tue,  5 Jun 2018 18:50:44 +0100	[thread overview]
Message-ID: <20180605175050.29850-2-tvrtko.ursulin@linux.intel.com> (raw)
In-Reply-To: <20180605175050.29850-1-tvrtko.ursulin@linux.intel.com>

From: Tvrtko Ursulin <tvrtko.ursulin@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.
