Gen >= 12 onwards MOCS table doesn't have a setting for PTE
so I915_MOCS_PTE is not a valid index and it will have different
MOCS values based on the platform.
To detect these kinds of misprogramming, all the unspecified and
reserved MOCS indexes are set to WB_L3.
This series also contains patches to program BLIT_CCTL and
CMD_CCTL registers to UC.
Since we are quite late to update MOCS table for TGL so added
a new MOCS table for ADL family.

drm/i915/gt: Set BLIT_CCTL reg to un-cached
Ayaz A Siddiqui (3):
drm/i915/gt: Add support of mocs propagation
drm/i915/gt: Initialize unused MOCS entries with device specific
values
drm/i95/adl: Define MOCS table for Alderlake
Srinivasan Shanmugam (1):
drm/i915/gt: Use cmd_cctl override for platforms >= gen12
