* draw: implement distance cullingZack Rusin2013-06-108-31/+198
| | | | | | | | | | | Works similarly to clip distance. If the cull distance is negative for all vertices against a specific plane then the primitive is culled.

* 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.

* i965/vs: Avoid the MUL/MACH/MOV sequence for small integer multiplies.Eric Anholt2013-06-101-13/+37
| | | | | | | | | | | | | | | We do a lot of multiplies by 3 or 4 for skinning shaders, and we can avoid the sequence if we just move them into the right argument of the MUL. On pre-IVB, this means reliably putting a constant in a position where it can't be constant folded, but that's still better than MUL/MACH/MOV.

* 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.

* intel: Reserve less batchbuffer space.Kenneth Graunke2013-06-101-4/+3
| | | | | | | | | | | | | | | Now that Gen6+ relies on hardware contexts, we don't need to record an occlusion query value at the end of each batch. That means we no longer need to reserve space for the absurd number of PIPE_CONTROLs required to do that on Sandybridge. See commit 4e087de51ad0e7ba4a7199d3664e1d096f8dc510, which bumped this up to 60 bytes. This is not quite a revert, as it uses 24 bytes instead of 16, and saves the comments.

| | | | | | | | | | | | | | | | | | | If we didn't successfully parse the #version line, there's no point in continuing with parsing and compiling: it's already failed. Furthermore, it can actually be harmful: right after handling #version, we call _mesa_glsl_initialize_types(), which checks state->es_shader and language_version. If it isn't valid, it hits an assertion failure. Fixes Piglit's "invalid-version-es." When processing "#version 110 es", our code set state->es_shader and state->language_version = 110. It then properly determined that this was invalid and flagged an error. Since we continued anyway, we hit the assertion mentioned above. NOTE: This is a candidate for the 9.1 branch.

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.

* 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]>

* 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]>

* intel: flush fake front buffer more robustly.Paul Berry2013-06-071-11/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | When a fake front buffer is in use, if we request the front buffer (using screen->dri2.loader->getBuffersWithFormat()), the X server copies the real front buffer to the fake front buffer and returns the fake front buffer. We sometimes make redundant requests for the front buffer (due to using a single counter to track invalidates for both the front and back buffers), so there's a danger of pending front buffer rendering getting overwritten when the redundant front buffer request occurs. Previous to this patch, intel_update_renderbuffers() worked around that problem by sometimes doing intel_flush() and intel_flush_front() before calling intel_query_dri2_buffers(). But it only did the workaround when the front buffer was bound for drawing; it didn't do it when the front buffer was bound for reading. This patch moves the workaround code to intel_query_dri2_buffers(), so that it happens in exactly the circumstances where it is needed. This should fix some of the sporadic failures in Piglit tests fbo-sys-blit and fbo-sys-sub-blit. Reviewed-by: Chad Versace <[email protected]> Reviewed-by: Anuj Phogat <[email protected]>
