212
* 1) The zbuffer must be micro-tiled and whole microtiles must be
213
* written if compression is enabled. If microtiling is disabled,
216
* 2) There is ZMASK RAM which contains a compressed zbuffer.
217
* Each dword of the Z Mask contains compression information
218
* for 16 4x4 pixel tiles, that is 2 bits for each tile.
219
* On chips with 2 Z pipes, every other dword maps to a different
220
* pipe. On newer chipsets, there is a new compression mode
221
* with 8x8 pixel tiles per 2 bits.
223
* 3) The FASTFILL bit has nothing to do with filling. It only tells hw
224
* it should look in the ZMASK RAM first before fetching from a real
227
* 4) If a pixel is in a cleared state, ZB_DEPTHCLEARVALUE is returned
228
* during zbuffer reads instead of the value that is actually stored
229
* in the zbuffer memory. A pixel is in a cleared state when its ZMASK
230
* is equal to 0. Therefore, if you clear ZMASK with zeros, you may
231
* leave the zbuffer memory uninitialized, but then you must enable
232
* compression, so that the ZMASK RAM is actually used.
234
* 5) Each 4x4 (or 8x8) tile is automatically decompressed and recompressed
235
* during zbuffer updates. A special decompressing operation should be
236
* used to fully decompress a zbuffer, which basically just stores all
237
* compressed tiles in ZMASK to the zbuffer memory.
239
* 6) For a 16-bit zbuffer, compression causes a hung with one or
240
* two samples and should not be used.
242
* 7) FORCE_COMPRESSED_STENCIL_VALUE should be enabled for stencil clears
243
* to avoid needless decompression.
245
* 8) Fastfill must not be used if reading of compressed Z data is disabled
246
* and writing of compressed Z data is enabled (RD/WR_COMP_ENABLE),
247
* i.e. it cannot be used to compress the zbuffer.
249
* 9) ZB_CB_CLEAR does not interact with zbuffer compression in any way.
