* gallium: add a cull distance semanticZack Rusin2013-06-105-2/+20
| | | | | | | | | | | | | cull distance is analogous to clip distance. If a register is given this semantic, then the values in it are assumed to be a float32 distance to a plane. Primitives will be completely discarded if the plane distance for all of the vertices in the primitive are < 0.

* draw: fix clipper invocation statisticsZack Rusin2013-06-105-6/+33
| | | | | | | | | | | | | We need to figure out the number of invocations of the clipper before the emit, because in the emit we are after clipping where the number of primitives will be equal to number of clipper invocations minus the clipped primitives. So our computations were always off by the number of clipped primitives.

* draw: enable user plane clipping when clipdistance is usedZack Rusin2013-06-102-7/+20
| | | | | | | | | | | | | | | | | Draw depended on clip_plane_enable being set in the rasterizer to use clipdistance registers for clipping. That's really unfriendly because it requires that rasterizer state to have variants for every shader out there. Instead of depending on the rasterizer lets extract the info from the available state: if a shader writes clipdistance then we need to use it and we need to clip using a number of planes equal to the number of writen clipdistance components. This way clipdistances just work.

* draw: Fix type mismatch between draw_private.h and LLVMRichard Sandiford2013-06-101-1/+1
| | | | | | | | | | | | | | | draw_vertex_buffer declared the size field to be a size_t, but the LLVM code used an int32 instead. This caused problems on big-endian 64-bit targets, because the first 32-bit chunk of the 64-bit size_t was always 0. In one sense size_t seems like a good choice for a size, so one fix would have been to try to get the LLVM code to use the equivalent of size_t too. However, in practice, the size is taken from things like ~0 or width0, both of which are int-sized, so it seemed simpler to make the size field int-sized as well.

* util: Use sizeof(void *) rather than 0 as the fallback cache line sizeRichard Sandiford2013-06-101-0/+5

* llvmpipe: Use saturating add/sub for UNORM formatsRichard Sandiford2013-06-101-0/+8
| | | | | | | | | | | | | | | | | | lp_build_add and lp_build_sub have fallback code for cases that cannot be handled by known intrinsics. For UNORM formats, this code was using modulo rather than saturating arithmetic. This fixes some rendering issues for a gnome session on System z. It also fixes various piglit tests on z, such as spec/ARB_color_buffer_float/GL_RGBA8-render. The patch deliberately doesn't tackle the more complicated SNORM case. Tested against piglit on x86_64 and System z with no regressions. Reviewed-by: Adam Jackson <[email protected]> Signed-off-by: Richard Sandiford <[email protected]>

* freedreno: gmem bypassRob Clark2013-06-087-30/+168
| | | | | | | | | | | | | The GPU (at least a3xx, but I think also a2xx) can render directly to memory, bypassing tiling. Although it can't do this if blend, depth, and a few other features of the pipeline are enabled. This direct memory mode can be faster for some sorts of operations, such as simple blits. In particular, this significantly speeds up XA by avoiding to pull the entire dest pixmap into GMEM, render tiles, and write it all back out again. This should also speed up resource copy-region and blit. Signed-off-by: Rob Clark <[email protected]>
* freedreno: add a3xx supportRob Clark2013-06-0835-3/+8955
| | | | | | | | | | | | | | | | | | | | The adreno a3xx GPU is found in newer snapdragon devices, such as the nexus4. The a3xx is GLESv3 and OpenCL capable, although that is not enabled yet in gallium. Compared to a2xx, it introduces an entirely new unified shader ISA, and re-shuffles all or nearly all of the registers. The good news is that (for the most part) the registers are more orthogonal, not combining unrelated state in a single register. And that there is a lot more flexibility, so we don't need to patch and re-emit the shader like we did on a2xx. The shader compiler is currently quite dumb, there would be a lot of room for improvement with an optimizing pass. Despite that, with the a320 in my nexus4 it seems to be ~2-3x faster compared to the a220 in my HP touchpad. Signed-off-by: Rob Clark <[email protected]>
* freedreno: prepare for a3xxRob Clark2013-06-0849-2008/+2798

* gallivm: work around slow code generated for interleaving 128bit vectorsRoland Scheidegger2013-06-081-0/+22
| | | | | | | | | | | | | | | We use 128bit vector interleave for untwiddling in the blend code (with 256bit vectors). llvm generates terrible code for this for some reason, so instead of generating a shuffle for 2 128bit vectors use a extract/insert shuffle instead (it only seems to matter we're not using 128bit wide vectors for the shuffle). This decreases instruction count of the blend code generated for a rgba8 render target without blending from 169 to 113 with llvm 3.1 and from 136 to 114 in llvm 3.2/3.3, and I got a ~8% (llvm 3.1) and ~5% (3.2/3.3) performance improvement in gears. (The generated code is still not terribly good as we could actually avoid the interleaving completely but llvm can't know this.) Reviewed-by: Jose Fonseca <[email protected]>
