linux-next: manual merge of the drm tree with the drm-intel-fixes tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Dave,

Today's linux-next merge of the drm tree got a conflict in
drivers/gpu/drm/i915/intel_ringbuffer.c between commit 4f47c99a9be7 ("drm/i915:
Move WaBarrierPerformanceFixDisable:skl to skl code from chv code") from the
drm-intel-fixes tree and commit b62adbd1ea1f ("drm/i915/bxt: Move
WaForceEnableNonCoherent to Skylake only") from the drm tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

cheers
