commit e5756c10 Author: Imre Deak <imre.deak@intel.com> Date: Fri Aug 14 18:43:30 2015 +0300 drm/i915/bxt: don't allow cached GEM mappings on A stepping Added an exception of disallowing snooping for Broxton A stepping hardware but userptr was still enabling it regardless. Move the check to HAS_SNOOP now that it is used from multiple call sites and use it. v2: Userptr cannot be supported when it cannot be coherent and generalize the code better. (Chris Wilson) v3: Make has_snoop true only when !has_llc. (Chris Wilson) Signed-off-by:
