* llvmpipe: improve rasterization discard logicRoland Scheidegger2018-05-231-1/+0
| | | | | | | | | | | | | | | | | | | | | | This unifies the explicit rasterization discard as well as the implicit rasterization disabled logic (which we need for another state tracker), which really should do the exact same thing. We'll now toss out the prims early on in setup with (implicit or explicit) discard, rather than do setup and binning with them, which was entirely pointless. (We should eventually get rid of implicit discard, which should also enable us to discard stuff already in draw, hence draw would be able to skip the pointless clip and fallback stages in this case.) We still need separate logic for only null ps - this is not the same as rasterization discard. But simplify the logic there and don't count primitives simply when there's an empty fs, regardless of depth/stencil tests, which seems perfectly acceptable by d3d10. While here, also fix statistics for primitives if face culling is enabled. No piglit changes. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Jose Fonseca <[email protected]>

* gallium: remove pipe_index_buffer and set_index_bufferMarek Olšák2017-05-101-1/+0
| | | | | | | | | | | | | | pipe_draw_info::indexed is replaced with index_size. index_size == 0 means non-indexed. Instead of pipe_index_buffer::offset, pipe_draw_info::start is used. For indexed indirect draws, pipe_draw_info::start is added to the indirect start. This is the only case when "start" affects indirect draws. pipe_draw_info::index is a union. Use either index::resource or index::user depending on the value of pipe_draw_info::has_user_indices. v2: fixes for nine, svga
* llvmpipe: ditch additional ref counting for vertex/geometry sampler viewsRoland Scheidegger2016-01-151-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The cleaning up was quite a performance hog (making pipe_resource_reference the number two in profilers on the vertex path, and 3rd overall, with its cousin pipe_reference_described not far behind) if there were lots of tiny draw calls (ipers). Now the reason was really that it was blindly calling this for all potential shader views (so 32 each for vs and gs) even though the app never touched a single one which could have been fixed, however I can't come up with a good reason why we refcount these. We've got references, of course, in the sampler views, which should be quite sufficient as we do all vertex and geometry shader execution fully synchronous. (Calling prepare_shader_sampling for all draw calls even if there were no changes looks quite suboptimal too, but generally we don't really expect vs/gs shader sampling to be used much with llvmpipe, and there's even an early exit if there aren't any views to avoid the "null loop" albeit it's now no longer always trying to loop through all 32 slots. Maybe improve another time...). Of course, if we manage to make vertex loads run asynchronously some day, we need references again, but adding that back would be the least of the problems... Also only set LP_NEW_SAMPLER_VIEW for fragment sampler views. Nothing on the vertex side depends on it (I suppose we'd really wanted a separate flag in any case). (Good for a 3% improvement or so in ipers under the right conditions.) Reviewed-by: Jose Fonseca <[email protected]>

* llvmpipe: fix layer/vp input into fs when not written by prior stagesRoland Scheidegger2015-12-121-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | ARB_fragment_layer_viewport requires that if a fs reads layer or viewport index but it wasn't output by gs (or vs with other extensions), then it reads 0. This never worked for llvmpipe, and is surprisingly non-trivial to fix. The problem is the mechanism to handle non-existing outputs in draw is rather crude, it will simply redirect them to whatever is at output 0, thus later stages will just get garbage. So, rather than trying to fix this up (which looks non-trivial), fix this up in llvmpipe setup by detecting this case there and output a fixed zero directly. While here, also optimize the hw vertex layout a bit - previously if the gs outputted layer (or vp) and the fs read those inputs, we'd add them twice to the vertex layout, which is unnecessary. And do some minor cleanup, slots don't require that many bits, there was some bogus (but harmless) float/int mixup for psize slot too, make the slots all unsigned (we always put pos at pos zero thus everything else has to be positive if it exists), and make sure they are properly initialized (layer and vp index slot were not which looked fishy as they might not have got set back to zero when changing from a gs which outputs them to one which does not). This fixes the failures in piglit's arb_fragment_layer_viewport group (3 each for layer and vp). Reviewed-by: Jose Fonseca <[email protected]>

| | | | | | | | | | | | | | | | | In particular noone is interested in the vertex count, so drop that, and also drop the duplicated num_primitives_generated / so.primitives_storage_needed variables in drivers. I am unable for now to figure out if primitives_storage_needed in SO stats (used for d3d10) should increase if SO is disabled, though the equivalent num_primitives_generated used for OpenGL definitely should increase. In any case we were only counting when SO is active both in softpipe and llvmpipe anyway so don't pretend there's an independent num_primitives_generated counter which would count always. (This means the PIPE_QUERY_PRIMITIVES_GENERATED count will still be wrong just as before, should eventually fix this by doing either separate counting for this query or adjust the code so it always counts this even if SO is inactive depending on what's correct for d3d10.)

| | | | | | | | | | | | | | | | OpenGL doesn't support this but d3d10 does. It is a bit of a pain as it is necessary to keep track of queries still active at the end of a scene, which is also why I cheat a bit and limit the amount of simultaneously active queries to (arbitrary) 16 (simplifies things because don't have to deal with a real list that way). I can't think of a reason why you'd really want large numbers of overlapping/nested queries so it is hopefully fine.

This is needed to support dx10-style sampling instructions.

There are probably several reasons for that: - fetching itself is scalar - filtering is pure int code hence needs splitting anyway, same for the final texel offset calculations - texture wrap related code, which can be done 8-wide, is slightly more complex with floats (with clamp_to_edge) and float operations generally more costly hence probably not much faster overall - the code needed to split when encountering different mip levels for the quads, adding complexity So, just split always for aos path (but leave it 8-wide for soa, since we do 8-wide filtering there when possible). This should certainly be revisited if we'd have avx2 support.

If we do the wrapping with floats, we also need to set the weights accordingly. We can potentially end up with different (integer) coordinates than what the integer calculations would have chosen, which means the integer weights calculated previously in this case are completely wrong. Well at least that's what I think happens, at least recalculating the weights helps. (Some day really should refactor all the wrapping, so we do whatever is fastest independent of 16bit int aos or 32bit float soa filtering.)

It can also accept scalars for use with pseudo-vector intrinsics (only useful for float arguments, all x86 scalar simd float intrinsics use 4vf32). Only used for lp_build_min/max() for now (also added the scalar float case for these while there). (Other basic binary functions could use it easily, whereas functions with a different interface would need different helpers.) Expanding vectors isn't widely used, because we always try to use build contexts with native hw vector sizes. But it might (or not) be nicer if this wouldn't need to be done, the generated code should in theory stay the same (it does get hit by lp_build_rho though already since we didn't have a intrinsic for the scalar lp_build_max case before). v2: incorporated Brian's feedback, and also made the scalar min/max case work instead of crash (all scalar simd float intrinsics take 4vf32 as argument, probably the reason why it wasn't used before). Moved to lp_bld_intr based on José's request, and passing intrinsic size instead of length. Ideally we'd derive the source type info from the passed in llvm value refs and process some llvmtype return type so we could handle intrinsics where the source and destination type isn't the same (like float/int conversions, packing instructions) but that's a bit too complicated for now.

Until now these derivative values were just scalars, which isn't going to work. So we now use vectors, and since the interface needs to change we also do some different (slightly more efficient) packing of the values. For 8-wide vectors the packed derivative values for 3 coords would look like this, this scales to a arbitrary (multiple of 4) vector size: ds1dx ds1dy dt1dx dt1dy ds2dx ds2dy dt2dx dt2dy dr1dx dr1dy _____ _____ dr2dx dr2dy _____ _____ The second vector will be unused for 1d and 2d textures. To facilitate future changes the derivative values are put into a struct, since quite some functions just pass these values through. The generated code seems to be very slightly better for 2d textures (with 4-wide vectors) than before with sse2 (if you have a cpu with physical 128bit simd units - otherwise it's probably not a win). v2: suggestions from José, rename variables, add comments, use swizzle helper commit 0aa21de0d31466dac77b05c97005722e902517b8 Author: Roland Scheidegger <[email protected]> Date: Thu May 10 18:10:31 2012 +0200 gallivm: add undefined swizzle handling to lp_build_swizzle_aos This is useful for vectors with "holes", it lets llvm choose the most efficient shuffle instructions if some elements aren't needed without having to worry what elements to manually pick otherwise. commit 00faf3f370e7ce92f5ef51002b0ea42ef856e181 Author: José Fonseca <[email protected]> Date: Fri May 4 17:25:16 2012 +0100 gallivm: Get the LLVM IR optimization passes before JIT compilation.

We don't actually expect to hit these paths (hence don't fix them up to actually do the vector splitting) so just emit warnings (for those functions where it's obvious doing split/intrinsic is faster than using generic path). Only emit warnings for 256bit vectors since we _really_ don't expect to hit arbitrary large vectors which would affect a lot more functions. The warnings do not actually depend on avx since the same logic applies to plain sse2 too (but of course again there's _really_ no reason we should hit these functions with 256bit vectors without avx). commit 8a9ea701ea7295181e846c6383bf66a5f5e47637 Author: Roland Scheidegger <[email protected]> Date: Tue May 1 20:37:07 2012 +0200 gallivm: split vectors manually for avx in lp_build_pack2 (v2) There's 2 reasons for this: First, there's a llvm bug (fixed in 3.1) which generates tons of byte inserts/extracts otherwise, and second, more importantly, we want to use pack intrinsics instead of shuffles. We do this in lp_build_pack2 and not the calling code (aos sample path) because potentially other callers might find that useful too, even if for larger sequences of code using non-native vector sizes it might be better to manually split vectors. This should boost texture performance in the aos path considerably. v2: fix issues with intrinsics types with old llvm commit 27ac5b48fa1f2ea3efeb5248e2ce32264aba466e Author: Roland Scheidegger <[email protected]> Date: Tue May 1 20:26:22 2012 +0200 llvmpipe: refactor lp_build_pack2 (v2) prettify, and it's unnecessary to assert when there's no intrinsic due to unsupported bit width - the shuffle path will work regardless.

This does texture wrap modes with floats, and then the offset calculations still with ints (because of lack of precision with floats, though we could do some effort to make it work with not too large (16MB) textures). This also handles wrap repeat mode with npot-sized textures differently than either the old soa or aos int path (likely way faster but untested). Otherwise the actual address wrap code is largely similar to the soa path (not quite the same as this one also has some int code), it should get used by avx soa sampling later as well but doesn't handle more complex address modes yet (this will also have the benefit that we can use aos sampling path for all texture address modes). Generated code for that looks reasonable, but still does not split vectors explicitly for fetch/filter which means still get hit by llvm (fixed upstream) which generates hundreds of pinsrb/pextrb instead of two shuffles. It is not obvious though if it's much of a win over just doing address calcs 4-wide but with ints, even if it is definitely much less instructions on avx. piglit's texwrap seems to look exactly the same but doesn't test neither the non-normalized nor the npot cases. v2: fix comments, prettify based on Brian's and Jose's feedback. commit bffecd22dea66fb416ecff8cffd10dd4bdb73fce Author: Roland Scheidegger <[email protected]> Date: Thu Apr 19 01:58:29 2012 +0200 gallivm: refactor aos lp_build_sample_image_nearest/linear split them up to separate address calculations and fetching/filtering.

Because the complexity is quite high (cannot really be improved it seems, per-face selection would reduce complexity a lot but this leads to errors unless the derivatives are calculated all from the same face which almost doubles the work to be done) it is still slower than the branching version, hence only enable this with large vectors. It doesn't actually do per-quad face selection yet (only makes sense with matching lod selection, in fact it will select the same face for all pixels based on the average of the first four pixels for now) but only different shuffles are required to make it work (the branching version actually should work with larger vectors too now thanks to the improved horizontal add but of course it cannot be extended to really select the face per-quad unless doing branching per quad). commit 7780c58869fc9a00af4f23209902db7e058e8a66 Author: Roland Scheidegger <[email protected]> Date: Fri Mar 30 21:11:12 2012 +0100 llvmpipe: (trivial) fix compiler warning and also clarify comment regarding availability of popcnt instruction. commit a266dccf477df6d29a611154e988e8895892277e Author: Roland Scheidegger <[email protected]> Date: Fri Mar 30 14:21:07 2012 +0100 gallivm: remove unneeded members in lp_build_sample_context Minor cleanup, the texture width, height, depth aren't accessed in their scalar form anywhere.

We can still do better than that on AVX for packing to color buffer (by exploiting pack intrinsics characteristics hence eleminating the need for some clamps) but this already generates much better code. v2: incorporate feedback from José, Keith and use shuffle instead of bitcasts/extracts. Due to llvm deficiencies the latter cause all data to get moved to GPRs and back in pieces (even though the data in the regs actually stays the same...). commit c9970d70e05f95d3f52fe7d2cd794176a52693aa Author: Roland Scheidegger <[email protected]> Date: Fri Mar 23 19:33:19 2012 +0000 gallivm: fix bug in simple position interpolation Accidental use of position attribute instead of just pixel coordinates.

The code is more or less a per-pixel version adapted to only do it per quad. A per pixel version would be much simpler (could drop 2 selects, 6 broadcasts and the messy horizontal add of 3 vectors at the expense of only 2 more absolute value instructions - would also just work for arbitary large vectors). This version doesn't yet work with larger vectors because the horizontal add isn't adjusted to be able to work with 2x4 vectors (and also because face selection wouldn't be done per quad just per block though that would be only a correctness issue just as with lod selection). The downside is this code is quite a bit slower. On a Core2 it can be sped up by disabling the hw blend instructions for selection and using logicop fallbacks instead, but it is still slower than the old code, hence leave that in for now. Probably will chose one or the other version based on vector length in the end. commit b375fbb18a3fd46859b7fdd42f3e9908ea4ff9a3 Author: Roland Scheidegger <[email protected]> Date: Wed Mar 21 14:42:29 2012 +0000 gallivm: fix optimized occlusion query intrinsic name commit a9ba0a3b611e48efbb0e79eb09caa85033dbe9a2 Author: José Fonseca <[email protected]> Date: Wed Mar 21 16:19:43 2012 +0000 draw,gallivm,llvmpipe: Call gallivm_verify_function everywhere. commit f94c2238d2bc7383e088b8845b7410439a602071 Author: Roland Scheidegger <[email protected]> Date: Tue Mar 20 18:54:10 2012 +0000 gallivm: optimize calculations for cube maps a bit this does some more vectorized calculations and uses horizontal adds if possible.

It is improved to handle more than one quad at once, and also do some more vectorized calculations initially for slightly better code - newer cpus have full throughput with 4 wide float vectors, hence don't try to code up a path which might be faster if there's just one channel active per attribute. 2) just do straight interpolation for each pixel. Method 2) is more work per quad, but less initially - if all quads are executed significantly more overall though. But this might change with larger vector lengths. This method would also be needed if we'd do some kind of active quad merging when operating on multiple quads at once. This path contains some hack to force llvm to generate better code, it is still far from ideal though, still generates far too many unnecessary register spills/reloads. Both methods should work with different sized vectors. Not very well tested yet, still seems to work with four-wide vectors, need changes elsewhere to be able to test with wider vectors. commit be5d3e82e2fe14ad0a46529ab79f65bf2276cd28 Author: José Fonseca <[email protected]> Date: Fri Mar 16 20:59:37 2012 +0000 draw: Cleanup. commit f85bc12c7fbacb3de2a94e88c6cd2d5ee0ec0e8d Author: José Fonseca <[email protected]> Date: Fri Mar 16 20:43:30 2012 +0000 gallivm: More module compilation refactoring. commit d76f093198f2a06a93b2204857e6fea5fd0b3ece Author: José Fonseca <[email protected]> Date: Thu Mar 15 21:29:11 2012 +0000 llvmpipe: Use gallivm_compile/free_function() in linear code.

This code actually duplicated the (scalar) code calculating the determinant except it used different vertex order (leading to different sign but it doesn't matter) hence llvm could not have figured out it's the same (of course with determinant vectorized in the other place that wouldn't have worked any longer neither). Note this particular piece doesn't actually vectorize well, not many arithmetic instructions left but tons of shuffle instructions... Probably would need to work on n tris at a time for better vectorization. commit 63169dcb9dd445c94605625bf86d85306e2b4297 Author: Roland Scheidegger <[email protected]> Date: Thu Mar 8 03:11:37 2012 +0100 llvmpipe: vectorize some scalar code in setup reduces number of arithmetic instructions, and avoids loading vector x,y values twice (once as scalars once as vectors). Results in a reduction of instructions from 76 to 64 in fs setup for glxgears (16%) on a cpu with sse41. Since this code uses vec2 disguised as vec4, on old cpus which had physical 64bit sse units (pre-Core2) it probably is less of a win in practice (and if you have no vectors you can only hope llvm eliminates the arithmetic for unneeded elements). commit 732ecb877f951ab89bf503ac5e35ab8d838b58a1 Author: Roland Scheidegger <[email protected]> Date: Wed Mar 7 00:32:24 2012 +0100 draw: fix clipping bug introduced by 4822fea3f0440b5205e957cd303838c3b128419c broke clipping pretty badly (verified with lineclip test) commit ef5d90b86d624c152d200c7c4056f47c3c6d2688 Author: Roland Scheidegger <[email protected]> Date: Tue Mar 6 23:38:59 2012 +0100 draw: don't store vertex header per attribute storing the vertex header once per attribute is totally unnecessary.

If the code is stable then we might consider prefering the old JIT wherever possible. No change elsewhere. Reviewed-by: Roland Scheidegger <[email protected]>
* gallium: add void *user_buffer to pipe_constant_bufferMarek Olšák2012-04-301-0/+6
| | | | This reduces CPU overhead when updating constants.
* llvmpipe: Trim the fragment shader cached based on LLVM IR instruction count.José Fonseca2011-12-081-0/+1
| | | | | | | | | | | | Number of fragment shader variants is not very representative of the memory used by LLVM, neither is number of shader instructions, as often texture sampling constitutes most of the generated code. This change adds an additional trim criteria: least recently used fragment shader variants will be freed until the total number of LLVM IR instruction falls below a specified threshold.

* gallivm/llvmpipe: squash merge of the llvm-context branchBrian Paul2010-11-301-0/+13
| | | | | | | | | | | | | | This branch defines a gallivm_state structure which contains the LLVMBuilderRef, LLVMContextRef, etc. All data structures built with this object can be periodically freed during a "garbage collection" operation. The gallivm_state object has to be passed to most of the builder functions where LLVMBuilderRef used to be used.
