* tgsi/scan: use wrap-around shift behavior explicitly for file_maskRoland Scheidegger2018-03-061-1/+6
| | | | | | | | | | | | | | The comment said it will only represent the lowest 32 regs. This was not entirely true in practice, since at least on x86 you'll get masked shifts (unless the compiler could recognize it already and toss it out). It turns out this actually works out alright (presumably noone uses it for temp regs) when increasing max sampler views, so make that behavior explicit. Albeit it feels a bit hacky (but in any case, explicit behavior there is better than undefined behavior). Reviewed-by: Jose Fonseca <[email protected]> Reviewed-by: Brian Paul <[email protected]>

The result will be that each target that needs a specific driver can simply add `driver_<name>` to its dependencies line and the necessary libraries and compiler args will be added.

* llvmpipe: fix snorm blendingRoland Scheidegger2017-11-212-28/+159
| | | | | | | | | | | | | | | | | | | The blend math gets a bit funky due to inverse blend factors being in range [0,2] rather than [-1,1], our normalized math can't really cover this. src_alpha_saturate blend factor has a similar problem too. (Note that piglit fbo-blending-formats test is mostly useless for anything but unorm formats, since not just all src/dst values are between [0,1], but the tests are crafted in a way that the results are between [0,1] too.) v2: some formatting fixes, and fix a fairly obscure (to debug) issue with alpha-only formats (not related to snorm at all), where blend optimization would think it could simplify the blend equation if the blend factors were complementary, however was using the completely unrelated rgb blend factors instead of the alpha ones...

* meson: don't use build_by_default for specific gallium driversDylan Baker2017-11-131-1/+0
| | | | | | | | | | | | | | | | | | | Using build_by_default : false is convenient for dependencies that can be pulled in by various diverse components of the build system, the gallium hardware/software drivers and state trackers do not fit that description. Instead, these should be guarded using the variable that tracks whether that driver should be enabled. This leaves a few helper libraries: trace, rbug, etc, and the generic winsys bits as `build_by_default : false` because there are a large number of gallium components that pull them in. v2: - remove build_by_default from winsys convenience libs as well. v3: - Always put drivers before winsys for consistency Signed-off-by: Dylan Baker <[email protected]> Tested-by: Lionel Landwerlin <[email protected]> (v1) Reviewed-by: Eric Anholt <[email protected]>

* llvmpipe, gallivm: implement lod queries (LODQ opcode)Roland Scheidegger2017-09-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | This uses all the existing code to calculate lod values for mip linear filtering. Though we'll have to disable the simplifications (if we know some parts of the lod calculation won't actually matter for filtering purposes due to mip clamps etc.). For better or worse, we'll also disable lod calculation hacks (mostly should make a difference for cube maps) always - the issue with per-pixel lod being difficult is mostly because we then have different mipmaps needed for the actual texel fetch, which isn't a problem with lodq. We still use approximation for the log2 - for that reason I believe the float part of the lod is only accurate to about 4-5 bits (and one bit less with 1d textures actually) which is hopefully good enough (though d3d10 technically requires 6 bits - could use quadratic interpolation instead of linear to get 8 bits or so). Since lodq requires unclamped lod, we also have to move some sampler key calculations to texture sampling code - even if we know we're going to access mipmap 0 we still have to calculate lod and apply lod_bias for lodq. Passes piglit ARB_texture_query_lod tests (after having fixed the test). Reviewed-by: Jose Fonseca <[email protected]>

* llvmpipe, draw: improve shader cache debuggingRoland Scheidegger2017-09-091-9/+16
| | | | | | | | | | | | | | | | | With GALLIVM_DEBUG=perf set, output the relevant stats for shader cache usage whenever we have to evict shader variants. Also add some output when shaders are deleted (but not with the perf setting to keep this one less noisy). While here, also don't delete that many shaders when we have to evict. For fs, there's potentially some cost if we have to evict due to the required flush, however certainly shader recompiles have a high cost too so I don't think evicting one quarter of the cache size makes sense (and, if we're evicting based on IR count, we probably typically evict only very few or just one shader too). For vs, I'm not sure it even makes sense to evict more than one shader at a time, but keep the logic the same for now.

* llvmpipe: enable PIPE_CAP_QUERY_PIPELINE_STATISTICSRoland Scheidegger2017-09-091-1/+1
| | | | | | | | | | | | | | | | This was implemented since forever, but not enabled. It passes all piglit tests except one, arb_pipeline_statistics_query-frag. The reason is that the test (for drawing a 10x10 rect) expects between 100 and 150 pixel shader invocations. But since llvmpipe counts this with 4x4 granularity (and due to the rect being 2 tris) we end up with 224 invocations. I believe however what llvmpipe is doing violates neither the spirit nor the letter of the spec (our fragment shader granularity really is 4x4 pixels, albeit we will bail out early on 2x2 or 4x2 (the latter if AVX is available) granularity), the spec allows to count additional invocations due to implementation reasons.

* llvmpipe, draw: increase shader cache limitsRoland Scheidegger2017-09-071-3/+1
| | | | | | | | | | | | | | | We're not particularly concerned with memory usage, if the tradeoff is shader recompiles. And it's common for apps to have a lot of shaders nowadays (and, since our shaders include a LOT of context state of course we may create quite a bit more shaders even). So quadruple the amount of shaders draw will cache (from 128 to 512). For llvmpipe (fs shaders) quadruple the number of instructions, keep the number of variants the same for now (only with very simple, non-texturing shaders the variant limit could really be reached), and simplify the definition, it's probably easier to just have one different definition per branch...

| | | | | | | | | | | | | | | | If lp_setup_bind_framebuffer() is never called, then setup fb x1/y1 was not correctly initialized. This can happen if there's never a fb set - both cso and llvmpipe would consider setting this with no cbufs and no zsbuf a redundant change and therefore it would never get set. We rely on this setup fb rect being initialized correctly for the tri intersect tests, throwing away tris which don't intersect. Not initializing it meant we'd then say it intersected, and we'd try to bin that despite that we have no actual tiles to bin it to, leading to assertion failures (pretty harmless since tile 0/0 always exists nevertheless as tiles are statically allocated, albeit that should change at some point).
