2011-03-12r300g: implement fragment color clamping in the shaderMarek Olšák
This finishes the implementation of the fragment color clamp control for ARB_color_buffer_float. I don't wanna keep this stuff in a branch...
2011-02-10r300g: consolidate buffers and textures to r300_resourceMarek Olšák
Transfers and create/destroy are still handled separately.
2011-01-23r300g: Increase fragment shader limits for r400 cardsTom Stellard
r400 fragment shaders now support up to 64 temporary registers, 512 ALU instructions, and 512 TEX instructions.
2011-01-23r300/compiler: remove any code related to relative addressing of temporariesMarek Olšák
The hw can't do it and the code was useless anyway (it's lowered in the GLSL compiler).
2010-12-24r300g: add support for color0 writes to all bound color buffers.Dave Airlie
Thanks to Marek Olšák for making my initial attempt actually work. Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-12-03r300g: do not remove unused constants if we are not near the limitMarek Olšák
2010-10-18r300g: Add new debug option for logging vertex/fragment program statsTom Stellard
2010-09-28r300g: add support for 3D NPOT textures without mipmappingMarek Olšák
The driver actually creates a 3D texture aligned to POT and does all the magic with texture coordinates in the fragment shader. It first emulates REPEAT and MIRRORED wrap modes in the fragment shader to get the coordinates into the range [0, 1]. (already done for 2D NPOT) Then it scales them to get the coordinates of the NPOT subtexture. NPOT textures are now less of a lie and we can at least display something meaningful even for the 3D ones. Supported wrap modes: - REPEAT - MIRRORED_REPEAT - CLAMP_TO_EDGE (NEAREST filtering only) - MIRROR_CLAMP_TO_EDGE (NEAREST filtering only) - The behavior of other CLAMP modes is undefined on borders, but they usually give results very close to CLAMP_TO_EDGE with mirroring working perfectly. This fixes: - piglit/fbo-3d - piglit/tex3d-npot
2010-09-28r300g: code cleanupsMarek Olšák
Some random stuff I had here. 1) Fixed some misleading comments. 2) Removed fake_npot, since it's redundant. 3) lower_texture_rect -> scale_texcoords 4) Reordered and reindented some TEX transform code.
2010-09-10r300/compiler: Enable presubtract sourcesTom Stellard
The r300 compiler can now emit instructions that select from the presubtract source. A peephole optimization has been added to convert instructions like: ADD Temp[0].x, none.1, -Temp[1].x into the INV (1 - src0) presubtract operation.
2010-09-04r300g: add a new debug option which disables compiler optimizationsMarek Olšák
Those are: - dead-code elimination - constant folding - peephole (mainly copy propagation) - register allocation There are some bugs which I need to track down. Also fix up the descriptions of all the debug options.
2010-09-04r300/compiler: make optimizations not use 0.5 swizzles in vertex shadersMarek Olšák
2010-09-04r300/compiler: add new compiler parameter max_constantsMarek Olšák
2010-09-04r300g: only check for an empty shader if there are no compile errorsMarek Olšák
2010-09-04r300/compiler: add new compiler parameter max_alu_instsMarek Olšák
2010-08-25r300g: eliminate unused constants in FSMarek Olšák
2010-08-25r300g: eliminate unused constants in VSMarek Olšák
2010-08-25r300g: fix indentationMarek Olšák
2010-08-11r300g: implement gl_FrontFacingMarek Olšák
2010-08-09r300g: do not print shader compiler errors by defaultMarek Olšák
2010-08-03r300/compiler: r500 hw support for break and continue in loops.Tom Stellard
The BGNLOOP and ENDLOOP instructions are now being used correctly, which makes break and continue possible. The deadcode pass has been modified to handle breaks, and the compiler is more careful about which loops are unrolled.
2010-07-25r300g: do not use TXPITCH_EN if the width is POT and the height is NPOTMarek Olšák
2010-07-25r300g: cleanup texture creation codeMarek Olšák
This decouples initializing a texture layout/miptree description from an actual texture creation, it also partially unifies texture_create and texture_from_handle. r300_texture inherits r300_texture_desc, which inherits u_resource. The CBZB clear criteria are moved to r300_texture_desc::cbzb_allowed[level]. And other minor cleanups.
2010-07-03r300/compiler: Use hardware flow control instructions for loops on r500.Tom Stellard
2010-06-24r300g: reorder and cleanup register writes everywhereMarek Olšák
2010-06-13r300g: turn fragment shader into a CBMarek Olšák
2010-05-26r300/compiler: move hardware caps to the radeon_compiler base structMarek Olšák
Needed for vertex shaders too.
2010-05-23r300g: extend compile error messageMarek Olšák
2010-05-08r300g: pass depth texture swizzle to the compiler if compare mode is enabledMarek Olšák
2010-05-08r300g: respect compare mode regardless of sampler typeMarek Olšák
2010-05-08r300/compiler: generalize depth texture mode to support arbitrary swizzlesMarek Olšák
2010-04-26r300g: use the dummy FS shader for shaders with zero instructionsMarek Olšák
2010-04-17r300/compiler: add emulation of all mirrored-clamp wrap modes for NPOT texturesMarek Olšák
2010-04-16r300/compiler: fix repeat wrap mode for TXP and NPOTsMarek Olšák
No idea why st/mesa unnecessarily inserts TXP where TEX is sufficient. Also re-enabling the NPOT fallback for repeat in r300g.
2010-04-15r300/compiler: kill off RC_WRAP_CLAMPMarek Olšák
A variant thereof might be later reintroduced for the mirrored-clamp modes.
2010-04-15r300g: disable the REPEAT NPOT fallback until it worksMarek Olšák
It causes regressions. I haven't tested the MIRROR wrap modes, so not sure about that..
2010-04-15r300g: do not use NPOT fallback for CLAMP wrap modesMarek Olšák
These work just fine.
2010-04-15r300g: pick a new fragment shader when either a sampler state or view is changedMarek Olšák
2010-04-15r300g: fix regression in texdepth.Dave Airlie
texdepth stopped working when npot went in, this brings it back to life. < MostAwesomeDude> That looks like what I was going to do. Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-04-14r300g: fix possible crash when shader compilation failsMarek Olšák
This hopefully fixes the crash in the FDO bug #27634, not the bug itself.
2010-04-14r300g: make setting up fragment depth output less hackishMarek Olšák
2010-04-14r300g: kill off r300_fragment_shader::shadow_samplers and friendsMarek Olšák
2010-04-11r300/compiler: Implement texcoord repeat and mirror for NPOT.Corbin Simpson
2010-04-11r300g: Setup external state for wrap modes.Corbin Simpson
2010-04-11r300g: Cleanup fragment program external state setup.Corbin Simpson
2010-04-12r300g: atomize fragment shaderMarek Olšák
2010-04-12r300g: FS constants emission reworkMarek Olšák
* The constant buffer emission is separated from RC state variables emission. * The immediates are emitted with FS code.
2010-04-11r300g: use a dummy replacement fragment shader if the shader compilation failsMarek Olšák
Better than killing an application.
2010-04-11r300g: revisit some assertions and fix potential failuresMarek Olšák
* Turn some assertions to error messages. * At most 16 vertex elements can be set, others are ignored. * Rasterize at most 8 vertex-shader generic outputs, others are ignored. This includes fog and WPOS. * Unknown shader semantic names are ignored.
2010-04-11r300g: cleanup handling of sampler viewsMarek Olšák
The evolution of TX_FORMAT bits is as follows: * When a texture is created, set bits independent of pipe_format. * When a sampler view is created, add format-specific bits. * When sampler states and views are getting merged, add min/max LOD.
