[Intel-gfx] [PATCH dii-client 1/2] drm/i915: Make i915_coherent_map_type GT-centric

Jonathan Cavitt jonathan.cavitt at intel.com
Fri Jul 21 14:05:58 UTC 2023


Refactor i915_coherent_map_type to be GT-centric rather than
device-centric.  Each GT may require different coherency
handling due to hardware workarounds.
