Kenneth Graunke ab062639ed drm/i915: Whitelist SLICE_COMMON_ECO_CHICKEN1 on Geminilake. ... Geminilake requires the 3D driver to select whether barriers are intended for compute shaders, or tessellation control shaders, by whacking a "Barrier Mode" bit in SLICE_COMMON_ECO_CHICKEN1 when switching pipelines. Failure to do this properly can result in GPU hangs. Unfortunately, this means it needs to switch mid-batch, so only userspace can properly set it. To facilitate this, the kernel needs to whitelist the register. The workarounds page currently tags this as applying to Broxton only, but that doesn't make sense. The documentation for the register it references says the bit userspace is supposed to toggle only exists on Geminilake. Empirically, the Mesa patch to toggle this bit appears to fix intermittent GPU hangs in tessellation control shader barrier tests on Geminilake; we haven't seen those hangs on Broxton. v2: Mention WA #0862 in the comment (it doesn't have a name).
