For ease of use (i.e. avoiding a few checks and function calls), store the object's cache coherency next to the cache is dirty bit. Specifically this patch aims to reduce the frequency of no-op calls to i915_gem_object_clflush() to counter-act the increase of such calls for GPU only objects in the previous patch. v2: Replace cache_dirty & ~cache_coherent with cache_dirty && !cache_coherent as gcc generates much better code for the latter (Tvrtko) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Dongwon Kim <dongwon.kim@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Tested-by: Dongwon Kim <dongwon.kim@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170616105455.16977-1-chris@chris-wilson.co.uk Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> |
