Subject: [PATCH] drm/i915/skl: revert duplicated WaBarrierPerformanceFixDisable:skl
Date: Wed, 29 Jul 2015 12:21:22 -0700 [thread overview]
Message-ID: <1438197682-23297-1-git-send-email-marc.herbert@intel.com> (raw)
With this simple git diff command one can see that skl_init_workarounds()
got two copies of WaBarrierPerformanceFixDisable:skl:
git diff -U21 ca6e4405779e^1 ca6e4405779e drivers/gpu/drm/i915/intel_ringbuffer.c
This happened when the backmerge of drm-intel-fixes-2015-07-15
Merged the same fix on both sides. Same fix but not identical enough for
git: with a different surrounding context; hence the code duplication.
This commit merely reverts the output of the git command above
= the duplication introduced in the backmerge.
(This duplication was found while running git sanity checks on a
_linearized_ i915 forklift for ChromeOS.)
