Subject: [PATCH 4/4] drm/i915: Updated request structure tracing
Date: Fri, 26 Jun 2015 13:58:12 +0100	[thread overview]
Message-ID: <1435323492-28630-5-git-send-email-John.C.Harrison@Intel.com> (raw)
In-Reply-To: <1435323492-28630-1-git-send-email-John.C.Harrison@Intel.com>

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

Added the '_complete' trace event which occurs when a fence/request is signaled
as complete. Also moved the notify event from the IRQ handler code to inside the
notify function itself.

For: VIZ-5190
Signed-off-by: John Harrison <John.C.Harrison@Intel.com>
