render-test: Change D3D12 default to sm_6_5 (#8320)

2025-09-02T23:43:48+00:00

Changes default for render-test to sm_6_5. Since sm_6_5 is the new default, remove the -use-dxil option, add -use-dxcb option Remove -use-dxil option from all test cases. Add -use-dxcb to two tests that needed it. Fixes #7611

Hotfix/reenable vk test (#1969)

2021-10-08T15:19:56+00:00

* #include an absolute path didn't work - because paths were taken to always be relative. * Reenable erroneously disabled test.

Convert more tests to use shader objects (#1659)

2021-01-15T20:10:06+00:00

This change converts a large number of our existing tests to use the `ShaderObject` support that was added to the `gfx` layer. In many cases, tests were just updated to pass `-shaderobj` and the result Just Worked. In other cases, a `name` attribute had to be added to one or more `TEST_INPUT` lines. For tests that did not work with shader objects "out of the box," I spent a little bit of time trying to get them work, but fell back to letting those tests run in the older mode. Future changes to the infrastructure will be needed to get those additional tests working in the new path. Along with the changes to test files, the following implementation changes were made to get additional tests working: * Because the shader object mode uses explicit register bindings (from reflection), the hacky logic that was offseting `u` registers for D3D12 based on the number of render targets gets disabled (by another hack). * The "flat" reflection information coming from Slang was not correctly reporting "binding ranges" for things that consumed only uniform data (which would be everything on CUDA/CPU), so it was refactored to properly include binding ranges for anything where the type of the field/variable implied a binding range should be created (even if the `LayoutResourceKind` was `::Uniform`). * A few fixes were made to the CUDA implementation of `Renderer`, in order to get additional tests up and running. Most of these changes had to do with texture bindings, which hadn't really been tested previously. In addition, a few changes were made that were attempts at getting more tests working, but didn't actually help. These could be dropped if requested: * As a quality-of-life feature (not being used) the `object` style of `TEST_INPUT` line is upgraded to support inferring the type to use from the type of the input being set. * Any `object` shader input lines get ignored in non-shader-object mode.

Int64 atomic add RWByteAddressBuffer support (#1504)

2020-08-19T18:15:36+00:00

* Fix premake5.lua so it uses the new path needed for OpenCLDebugInfo100.h * Keep including the includes directory. * Added the spirv-tools-generated files. * We don't need to include the spirv/unified1 path because the files needed are actually in the spirv-tools-generated folder. * Put the build_info.h glslang generated files in external/glslang-generated. Alter premake5.lua to pick up that header. * First pass at documenting how to build glslang and spirv-tools. * Improved glsl/spir-v tools README.md * Added revision.h * Change how gResources is calculated. Update about revision.h * Update docs a little. * Split out spirv-tools into a separate project for building glslang. This was not necessary on linux, but *is* necessary on windows, because there is a file disassemble.cpp in spirv-tools and in glslang, and this leads to VS choosing only one. With the separate library, the problem is resolved. * Fix direct-spirv-emit output. * Update to latest version of spirv headers and spirv-tools. * Upgrade submodule version of glslang in external. * Add fPIC to build options of slang-spirv-tools * WIP adding support for InterlockedAddFp32 * Upgrade slang-binaries to have new glslang. * Fix issues with Windows slang-glslang binaries, via update of slang-binaries used. * WIP - atomicAdd. This solution can't work as we can't do (float*) in glsl. * WIP on atomic float ops. * Added checking for multiple decls that takes into account __target_intrinsic and __specialized_for_target. First pass impl of atomic add on float for glsl. * Split __atomicAdd so extensions are applied appropriately. * Made Dxc/Fxc support includes. Use HLSL prelude to pass the path to nvapi Added -nv-api-path * Refactor around IncludeHandler and impl of IncludeSystem * slang-include-handler -> slang-include-system Have IncludeHandler/Impl defined in slang-preprocessor * Small comment improvements. * Document atomic float add addition in target-compatibility.md. * CUDA float atomic support on RWByteAddressBuffer. * Add atomic-float-byte-address-buffer-cross.slang * Removed inappropriate-once.slang - the test is no longer valid when a file is loaded and has a unique identity by default. A test could be made, but would require an API call to create the file (so no unique id). Improved handling of loadFile - uses uniqueId if has one. * Work around for testing target overlaps - to avoid exceptions on adding targets. Simplify PathInfo setup. Modify single-target-intrinsic.slang - it no longer failed because there were no longer multiple definitions for the same target. * Int64 atomic add RwByteAddressBuffer support. * Fix typo in stdlib for int atomic ByteAddressBuffer. * Small fixes to int64 atomic test.
