Remove old code paths from render-test (#1760)

2021-03-17T19:55:30+00:00

* 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

Add a CPU renderer implementation (#1750)

2021-03-12T19:58:14+00:00

* Add a CPU renderer implementation This change adds a CPU back-end to `gfx` and ensures that most of our existing CPU tests pass when using it. Detailed notes: * Most of the CPU renderer implementation is copy-pasted from the CUDA case, so they share a lot of similar logic * The main addition to the CPU renderer is a semi-complete implementation of host-memory textures. The logic here handles all the main shapes (Buffer, 1D, 2D, 3D, Cube) and all the currently-supported `Format`s that are sample-able as-is (no D24S8). The implementation is not intended to be fast, and it currently only does nearest-neighbor sampling, but otherwise it tries to avoid cutting too many corners and should be ar reasonable starting point for a more complete (but not performance-oriented) implementation. * Refactored the CPU prelude `IRWTexture` interface to inherit from `ITexture`, since in most cases a single type will end up implementing both. It might be worth it to collapse it all down to a single interface later. * Changed the CPU prelude `ITexture`/`IRWTexture` interface so that it takes both a pointer *and* a size for output arguments. This change seems necessary to allow a shader variable declared as a `Texture2D` to fetch a single `float` when the underlying texture might be using RGBA32F. * Added to the `IComponentType` public API so that we can query a "host callable" for an entry point and not just a binary. * Turned off the `-shaderobj` flag on two tests that weren't yet compatible with shader objects but still had the flag left in on the path (since previously the CPU path always used the non-`gfx` non-shader-object logic anyway) * Disabled one test (`dynamic-dispatch-11`) that relied on the `ConstantBuffer` idiom that we know we are planning to chagne soon anyway. * Made a few changes to the CUDA path to bring it into line with what I added for the CPU path. These were mostly bug fixes around indexing logic for sub-objects and resources. * fixup

Convert more tests to use shader objects (#1659)

2021-01-15T20:10:06+00:00

This change converts a large number of our existing tests to use the `ShaderObject` support that was added to the `gfx` layer. In many cases, tests were just updated to pass `-shaderobj` and the result Just Worked. In other cases, a `name` attribute had to be added to one or more `TEST_INPUT` lines. For tests that did not work with shader objects "out of the box," I spent a little bit of time trying to get them work, but fell back to letting those tests run in the older mode. Future changes to the infrastructure will be needed to get those additional tests working in the new path. Along with the changes to test files, the following implementation changes were made to get additional tests working: * Because the shader object mode uses explicit register bindings (from reflection), the hacky logic that was offseting `u` registers for D3D12 based on the number of render targets gets disabled (by another hack). * The "flat" reflection information coming from Slang was not correctly reporting "binding ranges" for things that consumed only uniform data (which would be everything on CUDA/CPU), so it was refactored to properly include binding ranges for anything where the type of the field/variable implied a binding range should be created (even if the `LayoutResourceKind` was `::Uniform`). * A few fixes were made to the CUDA implementation of `Renderer`, in order to get additional tests up and running. Most of these changes had to do with texture bindings, which hadn't really been tested previously. In addition, a few changes were made that were attempts at getting more tests working, but didn't actually help. These could be dropped if requested: * As a quality-of-life feature (not being used) the `object` style of `TEST_INPUT` line is upgraded to support inferring the type to use from the type of the input being set. * Any `object` shader input lines get ignored in non-shader-object mode.

* Fix CUDA output of a static const array if values are all literals. * Fix bug in Convert definition. * Output makeArray such that is deconstructed on CUDA to fill in based on what the target type is. Tries to expand such that there are no function calls so that static const global scope definitions work. * Fix unbounded-array-of-array-syntax.slang to work correctly on CUDA. * Remove tabs. * Check works with static const vector/matrix. * Fix typo in type comparison. * Shorten _areEquivalent test. * Rename _emitInitializerList.
