Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2025-09-30T18:21:27+00:00 2025-09-30T18:21:27+00:00 James Helferty (NVIDIA) jhelferty@nvidia.com 2025-09-30T18:21:27+00:00 urn:sha1:8086adc90b69f3199767c0617e2c429ce6b27f67 Enables all tests/metal/ tests that can be easily enabled. These tests were not originally designed as render tests; they are generally being enabled for pipecleaning purposes, and will not be rigorously testing the corresponding funcitonality. Where they cannot be enabled as render tests, and a metallib test wasn't already enabled, a metallib test was enabled instead (where possible). Fixes #7892 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.

Also change WorkgroupSize function to allow use with mesh shading capability. Update pipeline/rasterization/mesh/task-simple.slang to test it in task and mesh stages. 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.

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> 2024-04-26T05:27:30+00:00 ArielG-NV 159081215+ArielG-NV@users.noreply.github.com 2024-04-26T05:27:30+00:00 urn:sha1:e91bd3b0bdc50f66bfd302ff079c65fba5126474 * Force Inline if reftype Fixes #3997. If we are using a refType, we now ForceInline. remarks: 1. Modifications were made in slang-ir-glsl-legalize to change how we translate GlobalParam proxy's into GlobalParam. a. We now handle the senario where a globalParam is used in multiple disjoint blocks (like 2 different functions). * try to figure out why CI fails but local works try to inline DispatchMesh, works locally, may fail on CI(?) * try another fix * add task tests + don't allow semi-early task-shader inline Task shader uses DispatchMesh which is a very big 'hack' where we check for the function name and modify the callees in very large ways. This function does inline, but it cannot inline early due to future mangling that this operation requires todo. This is reflected with the `[noRefInline]` modifier. It is a modifier so users may stop mandatory inlines with `__ref` parameter. 2024-04-23T19:14:21+00:00 Yong He yonghe@outlook.com 2024-04-23T19:14:21+00:00 urn:sha1:f1de1817ca10e34ec6a844100f10f0de3340c9f2 * Switch to direct-to-spirv backend as default. * Fix slang-test. * Fix. * Fix.
