Enable Rendering Buffer Compression
Enabling Rendering buffer compression (allocating buffers using I915_FORMAT_MOD_Y_TILED_CCS
modifier).
http://go/cros-intelrbc
Requirement:
Using modifier might require more resources than the system can support. Enabling RBC is dependent on the ability of Chrome to test-modeset before modesetting, and falling back to less demanding modifiers such as Linear modifier (crrev.com/c/2567263).
BUG: 979736
TEST: (Kohaku eDP(4K) with 4K external) and (Kohaku eDP and 2 external monitors)
