+ /* My notes about fastfill:
*
- * If fastfill is enabled, a few facts should be considered:
+ * 1) Only the zbuffer is cleared.
*
- * 1) Zbuffer must be micro-tiled and whole microtiles must be
- * written.
+ * 2) The zbuffer must be micro-tiled and whole microtiles must be
+ * written. If microtiling is disabled, it locks up.
*
- * 2) ZB_DEPTHCLEARVALUE is used to clear a zbuffer and Z Mask must be
- * equal to 0.
+ * 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) RB3D_COLOR_CLEAR_VALUE is used to clear a colorbuffer and
- * RB3D_COLOR_CHANNEL_MASK must be equal to 0.
+ * 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) ZB_CB_CLEAR can be used to make the ZB units help in clearing
- * the colorbuffer. The color clear value is supplied through both
- * RB3D_COLOR_CLEAR_VALUE and ZB_DEPTHCLEARVALUE, and the colorbuffer
- * must be set in ZB_DEPTHOFFSET and ZB_DEPTHPITCH in addition to
- * RB3D_COLOROFFSET and RB3D_COLORPITCH. It's obvious that the zbuffer
- * will not be cleared and multiple render targets cannot be cleared
- * this way either.
+ * 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) For 16-bit integer buffering, compression causes a hung with one or
+ * 5) For 16-bit zbuffer, compression causes a hung with one or
* two samples and should not be used.
*
- * 6) Fastfill must not be used if reading of compressed Z data is disabled
+ * 6) 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
* and writing of compressed Z data is enabled (RD/WR_COMP_ENABLE),
* i.e. it cannot be used to compress the zbuffer.
- * (what the hell does that mean and how does it fit in clearing
- * the buffers?)
+ *
+ * 8) ZB_CB_CLEAR does not interact with fastfill in any way.
*
