* gallium: Add MULTISAMPLE_Z_RESOLVE capAxel Davy2015-02-061-0/+2
| | | | | | | | | | | | | | | | Resolving a multisampled depth texture into a single sampled texture is supported on >= SM4.1 hw. It is possible some previous hw support it. The ability was tested on radeonsi and nvc0. Apparently is is also supported for radeon >= r700. This patch adds the MULTISAMPLE_Z_RESOLVE cap and add it to the drivers. It is advertised for drivers for which it is sure the ability is supported. Reviewed-by: Marek Olšák <[email protected]> Signed-off-by: Axel Davy <[email protected]>

* gallium: add TGSI_SEMANTIC_VERTEXID_NOBASE and TGSI_SEMANTIC_BASEVERTEXRoland Scheidegger2014-12-161-0/+2
| | | | | | | | | | | | | | | | | | | Plus a new PIPE_CAP_VERTEXID_NOBASE query. The idea is that drivers not supporting vertex ids with base vertex offset applied (so, only support d3d10-style vertex ids) will get such a d3d10-style vertex id instead - with the caveat they'll also need to handle the basevertex system value too (this follows what core mesa already does). Additionally, this is also useful for other state trackers (for instance llvmpipe / draw right now implement the d3d10 behavior on purpose, but with different semantics it can just do both). Doesn't do anything yet. And fix up the docs wrt similar values. v2: incorporate feedback from Brian and others, better names, better docs.

* llvmpipe: decrease MAX_SCENES from 2 to 1Roland Scheidegger2014-12-062-1/+13
| | | | | | | | | | | | | | | | | | Multiple scenes per context are meant to be used so a new scene can be built while another one is processed in rasterization. However, quite surprisingly, this does not actually work (and according to git log, possibly never did, though maybe it did at some point further back (5 years+) but was buggy) because we always wait immediately on the rasterizer to finish the scene when contexts (and hence setup/scene) is flushed. This means when we try to get an empty scene later, any old one is already empty again. Thus using multiple scenes is just a waste of memory (not too bad, since the additional scenes are guaranteed to be empty, which means their size ought to be one data block (64kB) plus the size of some structs), without actually really doing anything. (There is also quite some code for the whole concept of multiple scenes which doesn't really do much in practice, but keep it hoping the wait-on-scene-flush can be fixed some day.)

* llvmpipe: fix lp_test_arit denorm handlingRoland Scheidegger2014-11-251-1/+37
| | | | | | | | | | | | | | | | | | llvmpipe disables denorms on purpose (on x86/sse only), because denorms are generally neither required nor desired for graphic apis (and in case of d3d10, they are forbidden). However, this caused some arithmetic tests using denorms to fail on some systems, because the reference did not generate the same results anymore. (It did not fail on all systems - behavior of these math functions is sort of undefined when called with non-standard floating point mode, hence the result differing depending on implementation and in particular the sse capabilities.) So, for the reference, simply flush all (input/output) denorms manually to zero in this case. This fixes https://bugs.freedesktop.org/show_bug.cgi?id=67672.

* gallivm: fix alignment issue for vertex data fetchRoland Scheidegger2014-11-181-1/+2
| | | | | | | | | | | | | | We cannot guarantee that vertex buffers have the necessary alignment for fetching all AoS members at once (for instance 4x32bit XYZW data). We can however guarantee that for textures. This did not cause errors for older llvm versions but it now matters and will cause segfaults if the data happens to not be aligned. Thus we need to set alignment manually. (Note that we can't actually really guarantee data to be even element aligned due to offsets in vertex buffers being bytes and OpenGL allowing this, but it does not matter for x86 as alignment is only required for sse vectors - not sure what happens on other archs, however.) This fixes https://bugs.freedesktop.org/show_bug.cgi?id=85467.

| | | | | | | | | | | | | | | | | llvmpipe treats PIPE_FORMAT_Z32_FLOAT_S8X24_UINT as a bit of a special case, handling it as two 32-bit pieces rather than a single 64-bit block: /* 64bit d/s format is special already extracted 32 bits */ total_bits = format_desc->block.bits > 32 ? 32 : format_desc->block.bits; The format_desc describes the whole 64-bit block, so the z shift will be 32 for big-endian. But since we're accessing the z channel as a 32-bit value rather than a 64-bit value, we need to mask the shift with 31.

No piglit change when not using SOFTPIPE_USE_LLVM=1. Now that it can do the same tests with and without using llvm for vs/gs, with llvm more pass, the only things failing only with llvm seems to be edgeflags tests and vs/gs-pow-float-float (and for the latter I'm not convinced the zero tolerance it requires is somehow mandated by glsl).

* llvmpipe: change LP_MAX_SHADER_INSTRUCTIONS definitionRoland Scheidegger2014-08-211-1/+1
| | | | | | | | | | | | | This change will double cache size for branches which have a lower LP_MAX_SHADER_VARIANTS limit (it will not do anything on master). The reason is that nowadays shaders tend to be quite a bit larger than they were (they were big when llvmpipe didn't have a fs loop, got much smaller with that loop, and since then have gradually increased quite a bit though still smaller than without the fs loop for various reasons - among them being d3d10 compliance, usage of 8-wide vectors, non-swizzled blend code). Thus effectively less shaders would be cached (unless they were very small and the variant limit was hit first). Also, since we're getting rid of the IR nowadays, the cached shaders shouldn't need all that much memory actually.
