2010-01-15llvmpipe: asst code changes in lp_state_fs.cBrian Paul
2010-01-15llvmpipe: put labels on some value refsBrian Paul
2010-01-15llvmpipe: add extra flags to DEFINES, no CFLAGSBrian Paul
Doesn't make any real difference but -D flags are put into DEFINES everywhere else.
2010-01-14llvmpipe: implement scissor testingBrian Paul
The scissor test is implemented as another per-quad operation in the JIT code. The four scissor box params are passed via the lp_jit_context. In the JIT code we compare the quad's x/y coords against the clip bounds and create a new in/out mask that's AND'd with the main quad mask. Note: we should also do scissor testing in the triangle setup code to improve efficiency. That's not done yet.
2010-01-14llvmpipe: minor comment updateBrian Paul
2010-01-14llvmpipe: clean-up, fixing up frame dump/debug codeBrian Paul
2010-01-14gallium/util: added debug_dump_texture() and ppm outputBrian Paul
Now we can get dump debug images on Linux too.
2010-01-14llvmpipe: remove redundant code in llvmpipe_set_blend_color()Brian Paul
2010-01-14llvmpipe: assorted clean-ups in texture codeBrian Paul
2010-01-13llvmpipe: use one loop in lp_rast_clear_zstencil()Brian Paul
This is just a tiny bit faster.
2010-01-13llvmpipe: optimize lp_rast_clear_color() for non-gray colorsBrian Paul
This makes a big difference in progs that clear to a non-gray color. Some demos are 30-50% faster.
2010-01-13llvmpipe: minor assorted clean-upsBrian Paul
2010-01-13llvmpipe: check render targets before other texturesBrian Paul
2010-01-13llvmpipe: also check render target textures in lp_setup_is_texture_referenced()Brian Paul
2010-01-13llvmpipe: indentation fixesBrian Paul
2010-01-13llvmpipe: re-get scene pointer after flushingBrian Paul
2010-01-13llvmpipe: check for texture usage in all scenesBrian Paul
2010-01-13llvmpipe: add scene texture referencing codeBrian Paul
2010-01-13llvmpipe: added scene functions for texture reference countingBrian Paul
When a texture is used in the scene we add it to a list of texture references. The lp_scene_is_textured_referenced() function tells us if a texture is referenced by the scene.

2010-01-13llvmpipe: Opaque shader implies complete colormask too.José Fonseca
2010-01-13llvmpipe: Reset the bin when shading a whole tile with an opaque shader.José Fonseca
2010-01-13llvmpipe: add bin debuggerKeith Whitwell
Adjust definition of empty_bin according to what's actually in empty bins. We often have a state packet before/after load commands. Still need to do something about the fence packets.
2010-01-13llvmpipe: implement lp_rast_load_zstencilKeith Whitwell
Load zbuffer contents for binned scenes that don't start with a clear and which have a bound zbuffer.
2010-01-13llvmpipe: added debug warningBrian Paul
2010-01-13llvmpipe: comments and LLVMValueRef namingBrian Paul
2010-01-13llvmpipe: tweak subpixel_snap() arithmeticBrian Paul
This adjustment fixes some rasterization differences between llvmpipe and softpipe (and other renderers).
2010-01-13llvmpipe: improve empty-bin test furtherKeith Whitwell
Remove unused param, add comments. Thanks to Brian for review.
2010-01-13llvmpipe: improve empty-bin testKeith Whitwell
We emit at most two clear packets (color and z respectively).
2010-01-13llvmpipe: quick hack to short-circuit empty binsKeith Whitwell
2010-01-12llvmpipe: fix indentation, comment typoBrian Paul
2010-01-12llvmpipe: debug checks: make sure scene is empty at key pointsBrian Paul
2010-01-12llvmpipe: assert that we're putting data into a valid binBrian Paul
2010-01-12llvmpipe: clamp maxx,maxy to framebuffer size (in terms of tiles)Brian Paul
In some corner cases the right-most / bottom-most vertex can be right on the edge of the framebuffer. Because the maxx, maxy vals are computed with a series of float/int, pixel/tile transformations we can end up with maxx >= scene->x_tiles or maxy >= scene->y_tiles. This leads to putting data into bins that never get processed, or reset. This becomes stale data that can lead to segfaults. Clamping fixes this.
2010-01-12llvmpipe: added lp_scene_is_empty()Brian Paul
2010-01-12llvmpipe: silence unused var warningsBrian Paul
2010-01-12llvmpipe: remove unused #defineBrian Paul
2010-01-11llvmpipe: disable the all in/out test code for nowBrian Paul
It's still faster not to try to special case the "all pixels are known to be inside the triangle" case.
2010-01-11llvmpipe: move, update commentsBrian Paul
2010-01-11llvmpipe: refactor generate_fragment() codeBrian Paul
This will make it easier to generate multiple versions of the fragment code per variant.
2010-01-11llvmpipe: do the all-in test on the scalar c0 instead of vector c0Brian Paul
This still isn't faster, but committing it for posterity.
2010-01-11llvmpipe: force constant interpolation of flatshade colorsKeith Whitwell
Nice speedup for gears.
2010-01-11llvmpipe: remove opencoded constantKeith Whitwell
2010-01-11llvmpipe: remove scissor cliprect derived stateKeith Whitwell
Was previously calculating the intersection of the scissor rectangle and the framebuffer dimensions. Rendering is already restricted to framebuffer dimensions by other means, so scissor testing (when implemented) can just use the scissor state directly.
2010-01-10llvmpipe: initial mrt supportKeith Whitwell
Non-mrt apps work, and the code looks correct, but not many mrt test apps handy atm...
2010-01-08llvmpipe: optimize case when all four pixels are inside the triangleBrian Paul
When the incoming c0,c1,c2 values are equal to INT_MIN it means that all pixels are inside the triangle. Thus we can skip the detailed pixel inside/outside triangle tests. Use the new lp_build_if()/endif() functions to generate the branching code. The code is disabled ATM however because it's actually a little slower than the original code. A little more tuning may fix that though...
2010-01-08llvmpipe: fix more if/else/endif design bugsBrian Paul
