* i965: properly initialize brw->cs.base.stage to MESA_SHADER_COMPUTEKenneth Graunke2017-11-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This has a bit of a surprising effect: For the render pipeline, the upload_sampler_state_table atom emits 3DSTATE_BINDING_TABLE_POINTERS_XS. It tries to avoid this for compute: if (GEN_GEN >= 7 && stage_state->stage != MESA_SHADER_COMPUTE) { /* Emit a 3DSTATE_SAMPLER_STATE_POINTERS_XS packet. */ genX(emit_sampler_state_pointers_xs)(brw, stage_state); } ... However, we were failing to initialize brw->cs.base.stage, so it was left as 0 (MESA_SHADER_VERTEX), causing this condition to break. We then emitted 3DSTATE_SAMPLER_STATE_POINTERS_VS in GPGPU mode, when trying to upload CS samplers. Nothing good can come of this. Found by inspection while debugging a GPU hang. Jordan believes this helps the Deus Ex: Mankind Divided benchmark mode's stability when running with shader cache.

| | | | | | | | | | | | | | | | | | Add a check that tests whether the c++ compiler supports c++11, either by default, by adding the compiler flag -std=c++11, or by adding a compiler flag that the user has specified via the environment variable CXX11_CXXFLAGS. The test only does a very shallow check of c++11 support, i.e. it tests whether the define __cplusplus >= 201103L to confirm language support by the compiler, and it checks whether the header <tuple> is available to test the availability of the c++11 standard library. A make file conditional HAVE_STD_CXX11 is provided that is used in this patch to enable the test in st/mesa if C++11 support is available.

* nir,intel/compiler: Use a fixed subgroup sizeJason Ekstrand2017-11-074-28/+15
| | | | | | | | | | | | | | | | The GL_ARB_shader_ballot spec says that gl_SubGroupSizeARB is declared as a uniform. This means that it cannot change across an invocation such as a draw call or a compute dispatch. For compute shaders, we're ok because we only ever use one dispatch size. For fragment, however, the hardware dynamically chooses between SIMD8 and SIMD16 which violates the spec. Instead, let's just pick a subgroup size based on the shader stage. The fixed size we choose for compute shaders is a bit higher than strictly needed but there's no real harm in that. The advantage is that, if they do anything interesting with the value, NIR will see it as an immediate and can optimize better.

* nir/lower_subgroups: Lower ballot intrinsics to the specified bit sizeJason Ekstrand2017-11-075-31/+84
| | | | | | | | | | | | | | Ballot intrinsics return a bitfield of subgroups. In GLSL and some SPIR-V extensions, they return a uint64_t. In SPV_KHR_shader_ballot, they return a uvec4. Also, some back-ends would rather pass around 32-bit values because it's easier than messing with 64-bit all the time. To solve this mess, we make nir_lower_subgroups take a new parameter called ballot_bit_size and it lowers whichever thing it gets in from the source language (uint64_t or uvec4) to a scalar with the specified number of bits. This replaces a chunk of the old lowering code. Reviewed-by: Lionel Landwerlin <[email protected]> Reviewed-by: Iago Toral Quiroga <[email protected]>

For instance, if we have add(4) g38.2<4>D g38.1<8,2,4>D g38.2<8,2,4>D then the destination register will end up having a width of 2 with a horizontal stride of 4 and a vertical stride of 8.

* intel/eu: Make automatic exec sizes a configurable optionJason Ekstrand2017-11-073-14/+29
| | | | | | | | | | | | | | We have had a feature in codegen for some time that tries to automatically infer the execution size of an instruction from the width of its destination. For things such as fixed function GS, clipper, and SF programs, this is very useful because they tend to have lots of hand-rolled register setup and trying to specify the exec size all the time would be prohibitive. For things that come from a higher-level IR, however, it's easier to just set the right size all the time and the automatic exec sizes can, in fact, cause problems.

| | | | | | | | | | | | | | Originally we tried to handle this case based on slots_valid. However, there are a number of ways that this can go wrong. For one, we throw away any trailing slots which either aren't written or are set to VARYING_SLOT_PAD. Second, even if PSIZ is a valid slot, we may not actually write anything there. Between the lot of these, it was possible to end up in a case where we tried to do a regular URB write but ended up with a length of 1 which is invalid.

* intel/compiler/fs: Set up subgroup invocation as a system valueJason Ekstrand2017-11-071-13/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Subgroup invocation is computed using a vector immediate and some dispatch-aware arithmetic. Unfortunately, due to the vector arithmetic, and the fact that it's frequently read 16-wide, it's not something that can easily be CSEd by the back-end compiler. There are a few different possible approaches to this problem: 1) Emit the code to calculate the subgroup invocation on-the-fly and trust NIR to do the CSE. This is what we were doing. 2) Add a back-end instruction for the subgroup ID. This has the advantage of helping the back-end compiler with CSE but has the downside of very poor scheduling for the calculation because it has to be emitted in the back-end. 3) Emit the calculation at the top of the program and re-use the result. This gets rid of the CSE problem but comes at the cost of an extra live register. This commit switches us from 1) to 3). We choose to store the subgroup invocation values as a W type to reduce the impact of the extra live register. Trusting NIR and using 1) was fine but we're soon going to want to use the subgroup invocation value for other things in the back-end compiler and this makes it much easier to do without having to worry about CSE problems.
