* CELL: fix use of stencil value maskRobert Ellison2008-10-301-42/+112
| | | | | | | The Cell stencil tests were completely ignoring the stencil value mask. Now the original code paths are still used if the stencil value mask is all 1s; but code to use the mask for the stencil value and reference value comparisons is now emitted if the mask is not all 1s.

* CELL: stencil bug fixesRobert Ellison2008-10-305-13/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | Two definitive bugs in stenciling were fixed. The first, reversed registers in the generated Select Bytes (selb) instruction, caused the stenciling INCR and DECR operations to fail dramatically, putting new values in where old values were supposed to be and vice versa. The second caused stencil tiles to not be read and written from main memory by the SPUs. A per-spu flag, spu.read_depth, was used to indicate whether the SPU should be reading depth tiles, and was set only when depth was enabled. A second flag, spu.read_stencil, was set when stenciling was enabled, but never referenced. As stenciling and depth are in the same tiles on the Cell, and there is no corresponding TAG_WRITE_TILE_STENCIL to complement TAG_WRITE_TILE_COLOR and TAG_WRITE_TILE_Z, I fixed this by eliminating the unused "spu.read_stencil", renaming "spu.read_depth" to "spu.read_depth_stencil", and setting it if either stenciling or depth is enabled. I also added an optimization to the fragment ops generation code, that avoids calculating stencil values and/or stencil writemask when the stencil operations are all KEEP.
* cell: Added check for PIPE_FLUSH_RENDER_CACHE to cell_flush to fix black ↵Jonathan White2008-10-301-1/+1
| | | | blocks during st_readpixels due to a flush wait not happening in order to allow any previous rendering to complete.
* cell: add scalar param to emit_function_call() to indicate scalar function callsBrian Paul2008-10-291-34/+69
| | | | | Scalar calls only use the X component of the src regs and smear the result across the dest register's X/Y/Z/W.
* cell: use simd utilities for pow, exp2, log2Brian Paul2008-10-291-22/+6
|
* cell: fix a number of fence issuesBrian Paul2008-10-284-7/+30
| | | | Plus add assertions to check status, alignment, etc.
* cell: don't include libmisc.hBrian Paul2008-10-281-1/+0
| | | | Doesn't seem to be needed and fixes compilation with SDK 3.1 beta.
* cell: fix some problems when displaying to a PIPE_FORMAT_B8G8R8A8_UNORM screenBrian Paul2008-10-271-0/+3
|
* cell: Added support for untwiddling textures during glReadPixels. This ↵Jonathan White2008-10-272-7/+152
| | | | allows glReadPixels to work correctly on cell now and makes conformance tests that use pixel compares useable.
* cell: include pthread.hBrian Paul2008-10-221-0/+1
|
* cell: implement fencing for texture buffersBrian Paul2008-10-2213-19/+367
| | | | | | | If we delete a texture, we need to keep the underlying tiled data buffer around until any rendering that references it has completed. Keep a list of buffers referenced by a rendering batch. Unref/free them when the associated batch's fence is executed/signalled.

* cell: temporarily disable freeing of tiled texture memoryBrian Paul2008-10-201-0/+6
| | | | Allows glDrawPixels to work for now...
* cell: use an approximation in compute_lambda_2d() to avoid sqrtBrian Paul2008-10-171-2/+12
| | | | Though, the logf() call still needs attention.

|
* cell: use 7-bit weights in sample_texture_2d_bilinear_int()Brian Paul2008-10-171-31/+31
| | | | | This allows us to use 16-bit signed mul/add instructions. Had to used unsigned mul before and there's no unsigned mul/add instruction.
