Subject: [PATCH] drm/i915: fix WaInsertDummyPushConstPs
Date: Tue, 2 Aug 2016 09:36:53 +0100 [thread overview]
Message-ID: <1470127013-29653-1-git-send-email-matthew.auld@intel.com> (raw)
As pointed out by Chris Harris, we are using the wrong WA name, it
should in fact be WaToEnableHwFixForPushConstHWBug, also it should be
applied from C0 onwards for both BXT and KBL.
Fixes: 7b9005cd45f3 ("drm/i915: Add WaInsertDummyPushConstP for bxt and kbl")
