[PATCH v4 1/2] drm/i915/skl: Rework MOCS tables to keep common part in a define

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The MOCS tables are going to be very similar across platforms.

To reduce the amount of copied code, this patch rips the common part and
puts it into a definition valid for all gen9 platforms.
