+ /* My notes about Zbuffer compression:
*
- * 1) Only the zbuffer is cleared.
+ * 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) The zbuffer must be micro-tiled and whole microtiles must be
- * written. 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) There is Z Mask RAM which contains a compressed zbuffer and
- * it interacts with fastfill. We should figure out how to use it
- * to get more performance.
- * This is what we know about the Z Mask:
+ * 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.
*
- * Each dword of the Z Mask contains compression information
- * for 16 4x4 pixel blocks, that is 2 bits for each block.
- * On chips with 2 Z pipes, every other dword maps to a different
- * pipe.
+ * 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.
*
- * 4) ZB_DEPTHCLEARVALUE is used to clear the zbuffer and the Z Mask must
- * be equal to 0. (clear the Z Mask RAM with zeros)
+ * 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.
*
- * 5) For 16-bit zbuffer, compression causes a hung with one or
+ * 6) For a 16-bit zbuffer, compression causes a hung with one or
* two samples and should not be used.
*
- * 6) FORCE_COMPRESSED_STENCIL_VALUE should be enabled for stencil clears
+ * 7) FORCE_COMPRESSED_STENCIL_VALUE should be enabled for stencil clears
* to avoid needless decompression.
*
- * 7) Fastfill must not be used if reading of compressed Z data is disabled
+ * 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.
*
- * 8) ZB_CB_CLEAR does not interact with fastfill in any way.
+ * 9) ZB_CB_CLEAR does not interact with zbuffer compression in any way.
