Subject: [RFC PATCH 08/11] drm/i915: add OA config for 3D render counters
Date: Thu, 7 May 2015 15:15:51 +0100 [thread overview]
Message-ID: <1431008154-6833-9-git-send-email-robert@sixbynine.org> (raw)
In-Reply-To: <1431008154-6833-1-git-send-email-robert@sixbynine.org>
This enables access to some additional counters beyond the aggregating A
counters, adding a '3D' metric set configuration useful while profiling
3D rendering workloads.

Subject: [RFC PATCH 08/11] drm/i915: add OA config for 3D render counters
Date: Thu, 7 May 2015 15:15:51 +0100 [thread overview]
Message-ID: <1431008154-6833-9-git-send-email-robert@sixbynine.org> (raw)
In-Reply-To: <1431008154-6833-1-git-send-email-robert@sixbynine.org>
This enables access to some additional counters beyond the aggregating A
counters, adding a '3D' metric set configuration useful while profiling
3D rendering workloads.
