2009-09-01tgsi: remove redundant CND0 opcodeKeith Whitwell
Can be implemented with CMP src2, src1, src0
2009-09-01scons: Tool for LLVM. Gracefully disable llvmpipe if LLVM not found.José Fonseca
2009-08-31llvmpipe: Fallback to element-wise comparisons when no comparison intrinsic ↵José Fonseca
is available. Although selection of vector elements is valid LLVM IR, no machine target supports it yet. This is a last-resort option, but it allows llvmpipe to be used on any target supported by LLVM without modifications. Obviously better performance is attainable by emitting SIMD intrinsics where otherwise LLVM doesn't.
2009-08-31llvmpipe: In the abcense of a min/max intrinsic, use the comparison intrinsics.José Fonseca
2009-08-31llvmpipe: Actually commit lp_buffer.[ch].José Fonseca
Thanks Michel.
2009-08-30llvmpipe: Texture cache in 4 ubytes instead of 4 floats.José Fonseca
This is more a short term experiment than a long term commitment, as we'll need to support higher precision textures too, as this will all be be replaced by runtime generated code. With this change most Mesa demos fps increased around 10%. Not a huge improvement, but not a negligible one either.
2009-08-30llvmpipe: Use util_format_read_4f to read texture tiles.José Fonseca
2009-08-30llvmpipe: Texture cache is read-only. No need to flush.José Fonseca
2009-08-30llvmpipe: Eliminate internal pipe_buffer_map/unmap usage.José Fonseca
2009-08-29llvmpipe: List lp_buffer.c in the Makefile.José Fonseca
2009-08-29llvmpipe: Define an winsys for LLVM. Drop pipe_winsysJosé Fonseca
lp_winsys will eventually be unified with softpipe's eventually, but we are free to move quicker since we don't have the myriad of users yet. Will provide a pipe_winsys adaptor from Keith's softpipe-private-winsys soon.
2009-08-29llvmpipe: Update for changes in master.José Fonseca
2009-08-29llvmpipe: Isolate sampling from TGSI translation.José Fonseca
2009-08-29llvmpipe: Better structure dereference naming.José Fonseca
2009-08-29llvmpipe: Fix shader variant key construction.José Fonseca
Fixes the blank screen on non-64bit mode.
2009-08-29llvmpipe: Fix build.José Fonseca
2009-08-29llvmpipe: Merge all pixel format related files.José Fonseca
2009-08-29llvmpipe: Factor out and optimize the input interpolation.José Fonseca
Special attention is given to the interpolation of side by side quads. Multiplications are made only for the first quad. Interpolation of inputs for posterior quads are done exclusively with additions, and perspective divide if necessary.
2009-08-29llvmpipe: Pre-declare fetch_texel.José Fonseca
2009-08-29llvmpipe: Pass the alpha ref value and blend color in the jit context.José Fonseca
2009-08-29llvmpipe: Pass fragment context to generated function in a single structure.José Fonseca
2009-08-29llvmpipe: Structure manipulation helpers.José Fonseca
2009-08-29llvmpipe: Centralize the C <-> JIT interfaces in one place.José Fonseca
2009-08-29llvmpipe: Drop blend derived state.José Fonseca
Already included in the fragment shader.
2009-08-29llvmpipe: keep texture stride 16byte alignedKeith Whitwell
Fixes crash when resizing gears window.
2009-08-29llvmpipe: Squash the quad pipeline.José Fonseca
It had been reduced to one fixed stage.
2009-08-29llvmpipe: s/uni/scalar/.José Fonseca
More obvious name.
2009-08-29llvmpipe: Add a bunch of comments.José Fonseca
Description/rationale/to-do items, while I still remember them...
2009-08-29llvmpipe: Split off vs stuff from lp_state_fs.c.José Fonseca
lp_state_fs.c is already too big without it.
2009-08-29llvmpipe: Avoid duplicate clamping when converting between types.José Fonseca
2009-08-29llvmpipe: Generate the fragment pipeline into a single function.José Fonseca
Still hackish. Will document and optimize later.
2009-08-29llvmpipe: Get conversions working correctly for all integer types.José Fonseca
2009-08-29llvmpipe: Delete the quad polygon stipple stage.José Fonseca
Not used now -- stipple done by the draw module. May code generate later.
2009-08-29llvmpipe: Early depth testing.José Fonseca
2009-08-29llvmpipe: Disassemble beyond referred code beyond the RET instruction.José Fonseca
2009-08-29llvmpipe: Split control flow function declarations and notes.José Fonseca
2009-08-29llvmpipe: Back port recent softpipe-opt improvements from Keith.José Fonseca
2009-08-29llvmpipe: Don't limit the number of tiles in the cache.José Fonseca
2009-08-29llvmpipe: Clean dead tile cache code.José Fonseca
2009-08-29llvmpipe: Simplify tile clears. Use pipe_fill_rect instead of scratch tile.José Fonseca
2009-08-29llvmpipe: Start hiding llvmpipe_cached_tile.José Fonseca
2009-08-29llvmpipe: Drop depth/stencil support from tile cache.José Fonseca
2009-08-29llvmpipe: Code generate the depth test, and include in the shader.José Fonseca
Only 32bit depth/stencil surfaces supported for now. Stencil ops not implemented yet.
2009-08-29llvmpipe: Update texture block from format.José Fonseca
2009-08-29llvmpipe: Depth test to LLVM IR translation.José Fonseca
2009-08-29llvmpipe: Centralize mask update logic.José Fonseca
2009-08-29llvmpipe: Clamped float to unsigned norm via mantissa manipulation.José Fonseca
2009-08-29llvmpipe: Several fixes of the conversion test.José Fonseca
2009-08-29llvmpipe: Generate instrinsics for integer comparisons.José Fonseca
It is a little messy, given the available instrucions form SIMD integer comparisons is rather limited.
2009-08-29llvmpipe: Mention the ability to get microbenchmarks from the unit tests.José Fonseca
Even better would be to have a -h/--help option to the tests...
