2008-09-22cell: Added DPH instruction and verified against softpipe.Jonathan White
2008-09-19cell: make sure the fragment ops and fragment shader code buffer is at a ↵Brian Paul
32-byte boundary To make sure even/odd instructions hit the right pipes.
2008-09-19cell: Added FRC instructionJonathan White
2008-09-19cell: Added FLR instruction. Verified the following instructions match ↵Jonathan White
softpipe: MOV, ADD, MUL, SGE, SUB, MAD, ABS, SLT, MIN, MAX, LRP, DP3, DP4, CMP, FLR
2008-09-19cell: Fixed bugs with DP3 and DP4, they match softpipe results now.Jonathan White
2008-09-19cell: flesh out support for other Z/stencil formatBrian Paul
Also: improve float/int Z conversion. Use clgt instead of cgt in depth test since we're comparing unsigned values.
2008-09-19cell: issue warning to stderr when using fallback fragment opsBrian Paul
2008-09-19cell: fix a commentBrian Paul
2008-09-19cell: the test for CELL_DEBUG_FRAGMENT_OP_FALLBACK in ↵Brian Paul
cmd_state_fragment_ops() was inverted
2008-09-19cell: change spe_complement() to take a src and dst reg, like other instructionsBrian Paul
2008-09-19CELL: add codegen for logic op, color maskRobert Ellison
- rtasm_ppc_spe.c, rtasm_ppc_spe.h: added a new macro function "spe_load_uint" for loading and splatting unsigned integers in a register; it will use "ila" for values 18 bits or less, "ilh" for word values that are symmetric across halfwords, "ilhu" for values that have zeroes in their bottom halfwords, or "ilhu" followed by "iohl" for general 32-bit values. Of the 15 color masks of interest, 4 are 18 bits or less, 2 are symmetric across halfwords, 3 are zero in the bottom halfword, and 6 require two instructions to load. - cell_gen_fragment.c: added full codegen for logic op and color mask.
2008-09-18CELL: mark several transient files as .gitignoreRobert Ellison
progs/demos: added new demo "fbo_firecube" progs/glsl: added new demo "pointcoord" src/gallium/drivers/cell/spu: added the g3d_spu executable, a Cell SPU executable file, which seems to be occasionally built as part of the cell driver src/glu/sgi: added "exptmp", a byproduct of the "mklib" process that sometimes gets deleted and sometimes not.
2008-09-18cell: Added CMP instructionJonathan White
2008-09-18cell: Fix bug with complement logic for SGE and SLEJonathan White
2008-09-18cell: Added SGE and SLE instructions to dispatch functionJonathan White
2008-09-18cell: Added SGE and SLE instructionsJonathan White
2008-09-18CELL: finish fragment ops blending (except for unusual D3D modes)Robert Ellison
- Added new "macro" functions spe_float_min() and spe_float_max() to rtasm_ppc_spe.{ch}. These emit instructions that cause the minimum or maximum of each element in a vector of floats to be saved in the destination register. - Major changes to cell_gen_fragment.c to implement all the blending modes (except for the mysterious D3D-based PIPE_BLENDFACTOR_SRC1_COLOR, PIPE_BLENDFACTOR_SRC1_ALPHA, PIPE_BLENDFACTOR_INV_SRC1_COLOR, and PIPE_BLENDFACTOR_INV_SRC1_ALPHA). - Some revamping of code in cell_gen_fragment.c: use the new spe_float_min() and spe_float_max() functions (instead of expanding these calculations inline via macros); create and use an inline utility function for handling "optional" register allocation (for the {1,1,1,1} vector, and the blend color vectors) instead of expanding with macros; use the Float Multiply and Subtract (fnms) instruction to simplify and optimize many blending calculations.
2008-09-17cell: example of doing fs/fm sequence with fnms in blendingBrian Paul
2008-09-17cell: dump generated code if CELL_DEBUG=asmBrian Paul
2008-09-17CELL: fleshing out the blending fragment opsRobert Ellison
- Added two new debug flags (to be used with the CELL_DEBUG environment variable). The first, "CELL_DEBUG=fragops", activates SPE fragment ops debug messages. The second, "CELL_DEBUG=fragopfallback", will eventually be used to disable the use of generated SPE code for fragment ops in favor of the default fallback reference routine. (During development, though, the parity of this flag is reversed: all users will get the reference code *unless* CELL_DEBUG=fragopfallback is set. This will prevent hiccups in code generation from affecting the other developers.) - Formalized debug message usage and macros in spu/spu_main.c. - Added lots of new code to ppu/cell_gen_fragment.c to extend the number of supported source RGB factors from 4 to 15, and to complete the list of supported blend equations. More coming, to complete the source and destination RGB and alpha factors, and to complete the rest of the fragment operations...

Only one level of if/else/endif nesting is currently working.

Also remove old code, etc.
2008-09-12cell: disable calls to old gen codeBrian Paul
2008-09-11cell: initial support for fragment shader code generation.Brian Paul
TGSI shaders are translated into SPE instructions which are then sent to the SPEs for execution. Only a few opcodes work, no swizzling yet, no support for constants/immediates, etc.
