* shader/texture: Join separate image and sampler pairs offlineReinUsesLisp2020-06-051-43/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | Games using D3D idioms can join images and samplers when a shader executes, instead of baking them into a combined sampler image. This is also possible on Vulkan. One approach to this solution would be to use separate samplers on Vulkan and leave this unimplemented on OpenGL, but we can't do this because there's no consistent way of determining which constant buffer holds a sampler and which one an image. We could in theory find the first bit and if it's in the TIC area, it's an image; but this falls apart when an image or sampler handle use an index of zero. The used approach is to track for a LOP.OR operation (this is done at an IR level, not at an ISA level), track again the constant buffers used as source and store this pair. Then, outside of shader execution, join the sample and image pair with a bitwise or operation. This approach won't work on games that truly use separate samplers in a meaningful way. For example, pooling textures in a 2D array and determining at runtime what sampler to use. This invalidates OpenGL's disk shader cache :) - Used mostly by D3D ports to Switch

| | | | | This silences an assertion we were hitting and uses workgroup memory barriers when the game requests it.

* | shader/other: Implement thread comparisons (NV_shader_thread_group)ReinUsesLisp2020-05-221-0/+5
|/ | | | | | | | | | | Hardware S2R special registers match gl_Thread*MaskNV. We can trivially implement these using Nvidia's extension on OpenGL or naively stubbing them with the ARB instructions to match. This might cause issues if the host device warp size doesn't match Nvidia's. That said, this is unlikely on proper shaders. Refer to the attached url for more documentation about these flags. https://www.khronos.org/registry/OpenGL/extensions/NV/NV_shader_thread_group.txt

* | shader/memory: Implement ATOM.ADDReinUsesLisp2020-01-261-1/+1
|/ | | | | | | | | | | | | ATOM operates atomically on global memory. For now only add ATOM.ADD since that's what was found in commercial games. This asserts for ATOM.ADD.S32 (handling the others as unimplemented), although ATOM.ADD.U32 shouldn't be any different. This change forces us to change the default type on SPIR-V storage buffers from float to uint. We could also alias the buffers, but it's simpler for now to just use uint. While we are at it, abstract the code to avoid repetition.

* shader_ir: Implement VOTEReinUsesLisp2019-08-211-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement VOTE using Nvidia's intrinsics. Documentation about these can be found here https://developer.nvidia.com/reading-between-threads-shader-intrinsics Instead of using portable ARB instructions I opted to use Nvidia intrinsics because these are the closest we have to how Tegra X1 hardware renders. To stub VOTE on non-Nvidia drivers (including nouveau) this commit simulates a GPU with a warp size of one, returning what is meaningful for the instruction being emulated: * anyThreadNV(value) -> value * allThreadsNV(value) -> value * allThreadsEqualNV(value) -> true ballotARB, also known as "uint64_t(activeThreadsNV())", emits VOTE.ANY Rd, PT, PT; on nouveau's compiler. This doesn't match exactly to Nvidia's code VOTE.ALL Rd, PT, PT; Which is emulated with activeThreadsNV() by this commit. In theory this shouldn't really matter since .ANY, .ALL and .EQ affect the predicates (set to PT on those cases) and not the registers.
