Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2025-09-02T23:43:48+00:00 2025-09-02T23:43:48+00:00 James Helferty (NVIDIA) jhelferty@nvidia.com 2025-09-02T23:43:48+00:00 urn:sha1:f02b08490aa905f42a8d90381db84b1f8e409c0c 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 2025-03-12T11:44:57+00:00 Anders Leino aleino@nvidia.com 2025-03-12T11:44:57+00:00 urn:sha1:f4d5372d3354e62770b076b47892b5172223e98a * Add a simple interface parameter test Since there's no documentation, it's nice to have a simple test case in order to experiment with this feature of the testing framework. * Add shader entry point attributes to tests * Fix specialization arguments for tests - Add some missing arguments - Rremove one extraneous argument. * Stop using deprecated compile request in render-test Use a session object instead of the deprecated compile request object. This closes issue #4760. 2024-06-12T20:38:23+00:00 ArielG-NV 159081215+ArielG-NV@users.noreply.github.com 2024-06-12T20:38:23+00:00 urn:sha1:8813c610562b1c30222ec3ef0734ef601d43b617 * capability upgrade warning/error adjusted implementation + tests to support a warning/error if capabilities are implicitly upgraded and test accordingly. * add glsl profile caps * add GLSL and HLSL capabilities to the associated capability * syntax error in capdef * only error if user explicitly enables capabilities 1. changed testing infrastructure to not set a `profile` explicitly, 2. Added tests to be sure this works as intended with user API and with slangc command line * Change capability atom definitions and how Slang manages them to fix errors 1. most `glsl_spirv` version atoms have been removed from `.capdef`, instead we will translate `spirv` version atoms into `glsl_spirv` since there is no point in writing the same code twice in `.capdef` files to define `spirv` versions. 2. add spirv version, and hlsl sm version (and equivlent) capability dependencies 3. removed some stage requirments which were set on objects, keep the wrapper capabilities. I am keeping the wrapper capabilities since I am unaware on if there are stage limitations (spec says code in practice does not work). * check internal version instead of version profile (_spirv_1_5 vs. spirv_1_5) * remove unused OpCapability. adjust SPIRV version'ing again for glsl_spirv * apply workaround for glslang bug with rayquery usage * ensure capabilities targetted by a profile and added together by a user are valid * remove additions to `spirv_1_*` wrapper * spirv_* -> glsl_spirv fix * fix bug where incompatable profiles would cause invalid target caps * try to avoid joining invalid capabilities * fix the warning/error & printing * run through tests to fix capability system and test mistakes many mistakes were mesh shaders doing `-profile glsl_450+spirv_1_4`. This is not allowed for a few reasons 1. the test tooling does not handle arguments the same as `slangc` 2. glsl_450 core profile does not support mesh shaders, nor does spirv_1_4. sm_6_5 does work in this senario * set some sm_4_1 intrinsics to sm_4_0 * replace `GLSL_` defs with `glsl_` * swap the unsupported render-test syntax for working syntax * set d3d11/d3d12 profile defaults this is required since sm version changes compiled code & behavior * adjusted nvapi capabilities with atomics + d3d11 set to use sm_5_0 as per default * cleanup * address review * incorrect styling * change `bitscanForward` to work as intended on 32 bit targets --------- Co-authored-by: Yong He <yonghe@outlook.com> 2024-03-15T00:48:41+00:00 Ellie Hermaszewska ellieh@nvidia.com 2024-03-15T00:48:41+00:00 urn:sha1:d40931cc8bde13520ea45769cf94e7cc6cc9065f 2023-09-27T18:46:03+00:00 Ellie Hermaszewska ellieh@nvidia.com 2023-09-27T18:46:03+00:00 urn:sha1:8326248542c2196b4a4ba80f068adb8a0edd6006 * SPIR-V impl for SetMeshOutputCounts and DispatchMesh * Unsightly fix for legalization ordering differences between GLSL and SPIR-V * spelling * Start a new block after terminating one in the OpEmitMeshTasksExt SPIR-V asm block * Emit mesh shader decorations in SPIR-V * Mesh and task shader stages for spir-v * Output explicit gl builtins for spir-v * Be more hygenic when SOAizing mesh outputs * Do not create builtin paramter block for spirv mesh outputs * Pass mesh payloads around by ref * comment * less expected failure * remove unused * Add spirv op * Correct type query for default flat modifier --------- Co-authored-by: Yong He <yonghe@outlook.com> 2023-09-12T03:13:11+00:00 Ellie Hermaszewska ellieh@nvidia.com 2023-09-12T03:13:11+00:00 urn:sha1:09854a4596019ddb3bb315b8836b5c88e718cdc7 * Bump vulkan headers Also just use vulkan-headers as a submodule * Add drawMeshTasks to gfx graphics pipelines * Add DispatchMesh overload with no payload, with GLSL intrinsic * Require spirv 1.4 for mesh shaders * Add vulkan mesh shader feature discovery * Add mesh shader stage bits to vk-util * Add mesh and task shader support to render-test * Add mesh and task tests * Preserve "payload" specifier in task shaders * Add mesh shader pipeline support to gfx * Add TODO * Add numThreads attribute for amplification stage * Add payload to task shader test * Drop dependency on d3dx12 * Allow passing payloads from task to mesh shaders * regenerate vs projects * check DispatchMesh name correctly * Add mesh shader tests to failing tests * Detect wave-ops feature on vulkan * Add fuse-product to expected failures This fails because the global varaible `count` is not initialized * Add required extension to WaveMaskMatch SPIR-V impl * Remove meshShader member from pipeline desc * Identify mesh shader support on d3d12
