Subject: [Intel-gfx] [PATCH 1/8] drm/i915/gt: Rearrange vlv workarounds
Date: Wed, 6 Jan 2021 13:39:58 +0000 [thread overview]
Message-ID: <20210106134005.10279-1-chris@chris-wilson.co.uk> (raw)
Some rcs0 workarounds were being incorrectly applied to the GT, and so
we failed to restore the expected register settings after a reset.
