Subject: [PATCH] drm/i915: Whitelist context-local timestamp in the gen9 cmdparser
Date: Mon,  1 Jun 2020 17:19:42 +0100	[thread overview]
Message-ID: <20200601161942.30854-1-chris@chris-wilson.co.uk> (raw)

Allow batch buffers to read their own _local_ cumulative HW runtime of
their logical context.

Fixes: 0f2f39758341 ("drm/i915: Add gen9 BCS cmdparsing")
