Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2021-03-17T19:55:30+00:00 2021-03-17T19:55:30+00:00 Tim Foley tfoleyNV@users.noreply.github.com 2021-03-17T19:55:30+00:00 urn:sha1:6e5d85efb9fa5f647f7f0c7ef784a9fd09b29023 * Remove old code paths from render-test Historically, the `render-test` tool was using three different code paths: * One based on `gfx` and manual (non-reflection-based) parameter setting, used for OpenGL, D3D11, D3D12, and Vulkan * One for CPU that used reflection-based parameter setting but shared no code with the first * One for CUDA that used reflection-based parameter setting and shared some, but not all, code with the CPU path Recently we've updated `render-test` to include a fourth option: * Using `gfx` and the "shader object" system it exposes for a unified reflection-based parameter-setting system taht works across OpenGL, D3D11, D3D12, Vulkan, CUDA, and CPU This change removes the first three options and leaves only the single unified path. A sa result, a bunch of code in `render-test` is no longer needed, and the codebase no longer relies on things like the `IDescriptorSet`-related APIs in `gfx`. Several existing tests had to be disabled to make this change possible. Those tests will need to be audited and either re-enabled once we fix issues in the shader object system, or permanently removed if they don't test stuff we intend to support in the long run (e.g., global-scope type parameters, which aren't a clear necessity). * fixup: CUDA detection logic 2021-01-14T23:48:54+00:00 Yong He yonghe@outlook.com 2021-01-14T23:48:54+00:00 urn:sha1:f834f25794cfb746079e92d58c7410b767c57208 * COM-ify all slang-gfx interfaces. 2020-10-09T18:29:11+00:00 Yong He yonghe@outlook.com 2020-10-09T18:29:11+00:00 urn:sha1:fab1c9f4c745ba84983c2448646376799d461e96 2020-09-01T20:47:26+00:00 Yong He yonghe@outlook.com 2020-09-01T20:47:26+00:00 urn:sha1:5c56479c7b742f94ebf4a97d93826b2a5e4f279d * Support dynamic existential shader parameters in render-test * Fix linux build error. * Fixes. * Fix code review issues. * Fix gcc error. * More fixes. * More fixes. 2020-03-30T23:23:09+00:00 jsmall-nvidia jsmall@nvidia.com 2020-03-30T23:23:09+00:00 urn:sha1:ea7690558bca71ce3a9453adff4e0135352a352f * render feature for CUDA compute model. * Use SemanticVersion type. * Enable CUDA wave tests that require CUDA SM 7.0.
