Render Decompression is supported with Y-Tiled main surface. The CCS is linear and has 4 bits of data for each main surface cache line pair, a ratio of 1:256. Additional Clear Color information is passed from the user-space through an offset in the GEM BO. Add a new modifier to identify and parse new Clear Color information and extend Gen12 render decompression functionality to the newly added modifier.
