* Support SM6.9 with GFX (#7387)Jay Kwak2025-06-13

* Enable Windows full debug testsuite in CI (#7085)Gangzheng Tong2025-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Unify Debug Layer Control Logic and Add Disable Option for Debug Builds This PR refactors and unifies the debug layer control logic in slang-test. A new `-disable-debug-layers` option is introduced, allowing debug builds to skip enabling the validation (debug) layer. This is currently needed to ensure stability in the debug test suite. Previously, different toggles such as ENABLE_VALIDATION_LAYER, ENABLE_DEBUG_LAYER, and debugLayerEnabled were used inconsistently across different components of slang-test. This PR standardizes the logic by using a single variable, debugLayerEnabled, to control the enabling/disabling of the debug layer internally. Notes: By default, the debug/validation layer is enabled in debug builds and is not supported in release builds of slang-test. Fixes: #7132 * Disable spirv-opt for the DebugFunctionDefinition issue * Run debug build only in GCP machines * Fix VUID-vkCmdPipelineBarrier-pBufferMemoryBarriers-02818 dstAcessMask can't include VK_ACCESS_TRANSFER_READ_BIT when stage mask has VK_PIPELINE_STAGE_RAY_TRACING_SHADER_BIT_KHR * Set failed retry limit to 32 --------- Co-authored-by: slangbot <ellieh+slangbot@nvidia.com> Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>
* Fix intermittent failure of slang-unit-test-tool/ReplayRecord (#6981)Jay Kwak2025-05-02
| | | | | | | | | | | * Fix intermittent failure of slang-unit-test-tool/ReplayRecord Three problems are addressed: 1. the graphics driver sometimes returns nullptr from GetShaderIdentifier 2. `findRecordFileName()` may not find any records at all. 3. the return value from cleanupRecordFiles() overwrote the error value in `res` and it returned SLANG_OK even when there were errors. * Fix compiler warnings on Windows
* Fix precompiledTargetModule tests (#6455)cheneym22025-02-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Fix precompiledTargetModule tests Add SPIRV-Tool linker support to gfx unit tests and use the linker in precompileModule tests that use precompiled modules to reconstitute SPIRV shaders that were modularly compiled. Fix a Slang reference count bug in the precompile service. * Use sm_6_6 New DXC requires higher version for linkability. * Rename helper function, pass by reference * Link through slang-glslang * Add missing files * Fix metal * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Yong He <yonghe@outlook.com>
* Support cooperative vector (#6223)Jay Kwak2025-01-30
| | | | | | | * Support cooperative vector without Vulkan-header update Adding a Slang support for cooperative vector. But this commit doesn't have Vulkan-header update.
* Fix some robustness issues in the examples (#5984)Anders Leino2025-01-07
| | | | | | | | | | | | | | | * examples: Make hello-world example exit gracefully if VK cannot be initialized - Check if VK API function pointers are valid before using them - Return 0 and exit if VK initialization fails - Enable hello-world example * examples: Fixes for ray-tracing examples - Assert that accelleration structure buffer is not nullptr - Check if buffer creation succeeded before proceeding - This makes initialization not hang, but it still fails. Therefore, the test expectations are just updated to point to another issue. - Enable ray-tracing tests on Windows
