[Intel-gfx] [PATCH v4 1/4] drm/i915: store all subslice masks
Lionel Landwerlin
lionel.g.landwerlin at intel.com
Wed Nov 22 12:30:21 UTC 2017
Up to now, subslice mask was assumed to be uniform across slices. But
starting with Cannonlake, slices can be asymetric (for example slice0
has different number of subslices as slice1+). This change stores all
subslices masks for all slices rather than having a single mask that
applies to all slices.
