[PATCH 08/14] drm/i915: Cache PAT index used by the driver
Tvrtko Ursulin
tvrtko.ursulin at linux.intel.com
Fri Dec 1 14:07:35 UTC 2023
From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>
Eliminate a bunch of runtime calls to i915_gem_get_pat_index() by caching
the interesting PAT indices in struct drm_i915_private. They are static
per platfrom so no need to consult a function every time.
