Subject: [Intel-gfx] [PATCH v7 35/63] drm/i915: Increase ww locking for perf.
Date: Thu, 28 Jan 2021 17:25:44 +0100 [thread overview]
Message-ID: <20210128162612.927917-36-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <20210128162612.927917-1-maarten.lankhorst@linux.intel.com>
We need to lock a few more objects, some temporarily,
add ww lock where needed.
