19 * From the Sky Lake PRM:
20 * "The Color Control Surface (CCS) contains the compression status of
21 * the cache-line pairs. The compression state of the cache-line pair
22 * is specified by 2 bits in the CCS. Each CCS cache-line represents
23 * an area on the main surface of 16 x16 sets of 128 byte Y-tiled
24 * cache-line-pairs. CCS is always Y tiled."
25 *
26 * Since cache line pairs refers to horizontally adjacent cache lines,
27 * each cache line in the CCS corresponds to an area of 32x16 cache
28 * lines on the main surface. Since each pixel is 4 bytes, this gives
29 * us a ratio of one byte in the CCS for each 8x16 pixels in the
30 * main surface.
