| * |
| * 1) The zbuffer must be micro-tiled and whole microtiles must be |
| * written if compression is enabled. If microtiling is disabled, |
| * it locks up. |
| * |
| * 2) There is ZMASK RAM which contains a compressed zbuffer. |
| * Each dword of the Z Mask contains compression information |
| * for 16 4x4 pixel tiles, that is 2 bits for each tile. |
| * On chips with 2 Z pipes, every other dword maps to a different |
| * pipe. On newer chipsets, there is a new compression mode |
| * with 8x8 pixel tiles per 2 bits. |
| * |
| * 3) The FASTFILL bit has nothing to do with filling. It only tells hw |
| * it should look in the ZMASK RAM first before fetching from a real |
| * zbuffer. |
| * |
| * 4) If a pixel is in a cleared state, ZB_DEPTHCLEARVALUE is returned |
| * during zbuffer reads instead of the value that is actually stored |
| * in the zbuffer memory. A pixel is in a cleared state when its ZMASK |
| * is equal to 0. Therefore, if you clear ZMASK with zeros, you may |
| * leave the zbuffer memory uninitialized, but then you must enable |
| * compression, so that the ZMASK RAM is actually used. |
| * |
| * 5) Each 4x4 (or 8x8) tile is automatically decompressed and recompressed |
| * during zbuffer updates. A special decompressing operation should be |
| * used to fully decompress a zbuffer, which basically just stores all |
| * compressed tiles in ZMASK to the zbuffer memory. |
| * |
| * 6) For a 16-bit zbuffer, compression causes a hung with one or |
| * two samples and should not be used. |
| * |
| * 7) FORCE_COMPRESSED_STENCIL_VALUE should be enabled for stencil clears |
| * to avoid needless decompression. |
| * |
| * 8) Fastfill must not be used if reading of compressed Z data is disabled |
| * and writing of compressed Z data is enabled (RD/WR_COMP_ENABLE), |
| * i.e. it cannot be used to compress the zbuffer. |
| * |
| * 9) ZB_CB_CLEAR does not interact with zbuffer compression in any way. |
| * |
