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

Implement shader execution reordering support for OptiX (#7211)

2025-05-26T15:30:38+00:00

* Implement shader execution reordering support for OptiX Added OptiX backend support for Shader Execution Reordering (SER) features as outlined in issue #6647. This implementation: 1. Added CUDA target support for HitObject API 2. Implemented core SER functionality (TraceRay, MakeHit/Miss, Invoke) 3. Added OptiX-specific hit object handling functions 4. Added test case for OptiX SER functionality * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

* Add cluster geometry intrinsics for ray tracing - Added GetClusterID() method to HitObject class - Added CandidateClusterID() and CommittedClusterID() methods to RayQuery class - Added SPV_NV_cluster_acceleration_structure extension support - Added GL_NV_cluster_acceleration_structure extension support - Added test files for RayQuery and HitObject cluster methods Fixes #6431 * OpRayQueryGetIntersectionClusterIdNV - unrecognized spirv Disabling spirv backend for SPV_NV_cluster_acceleration_structure hlsl.meta.slang(18674): error 29100: unrecognized spirv opcode: OpRayQueryGetIntersectionClusterIdNV result:$$int = OpRayQueryGetIntersectionClusterIdNV &this $iCandidateOrCommitted; ^~~~~~ hlsl.meta.slang(18670): error 30019: expected an expression of type 'int', got 'void' return spirv_asm ^~~~~~~~~ ninja: build stopped: subcommand failed. * 6431 - Fix spirv opcode * Remove tests * Add relevant tests * Review - Simplify tests

Implement raytracing extension(s); resolves #3560 for GLSL & SPIR-V targets (#3675)

2024-03-15T20:14:32+00:00

The following PR implements raytracing extensions (GLSL_EXT_ray_tracing, GLSL_EXT_ray_query, GLSL_NV_shader_invocation_reorder & GLSL_NV_ray_tracing_motion_blur); for GLSL & SPIR-V targets. Fully implements all functions, built-in variables, & syntax; resolves #3560 for GLSL & SPIR-V Targets. notes of worth: * __rayPayloadFromLocation, __rayAttributeFromLocation, and __rayCallableFromLocation, were added as SPIR-V Intrinsics to refer to location's of raytracing objects in SPIR-V for when using GLSL syntax.
