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. |
