2021-03-15Enable `gfx::CUDADevice` on linux. (#1756)Yong He
2021-03-12Add a CPU renderer implementation (#1750)Tim Foley
* 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<float>` 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<IInterface>` 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

2020-12-07"Shader Toy" example and related fixes (#1629)Tim Foley
* "Shader Toy" example and related fixes This change introduces a new `shader-toy` example program that is primarily designed to show how Slang's features for type-based encapsulation and modularity can be applied to modularity for effects along the lines of those from `shadertoy.com`. The Example ----------- The example is being checked in with an example "toy" effect that I hastily put together, so that it would not be encumbered with any IP concerns. I wrote the effect using the shadertoy.com editor, so I can be sure it is valid GLSL. During bringup of the application I used a pre-existing and larger effect for testing, so some of the support code that was added is not being used at present. The big-picture idea here is to have an exmaple that shows how to modularize things using Slang interfaces and generics, and then to use the Slang compiler API to manage the compilation, composition, specialization, and linking steps. For better or worse this leads to the sequence of API calls involved being much longer than what was in something like the `hello-world` example. Future Work (Example) --------------------- There is a lot of room for improvement and expansion here, so this should be viewed as a checkpoint of work in progress rather than something I'm claiming as a finalized demonstration of all we'd like to achieve. Areas for future work include: * We need to copy the integration of "Dear, IMGUI" that was already done for the `model-viewer` example so that this example can have a UI. * Now that the compilation flow is broken into all these additional steps, it should be possible to have the application load multiple effects as distinct modules, and then provide a UI for switching between them. The chosen effect module would be used to specialize the top-level shader(s) before kernel generation. * The checked-in logic includes a compute shader that can execute an effect, but that hasn't been tested nor has it been wired up to any kind of UI. We should have a way to switch between multiple execution methods, with a goal of eventually including CPU execution. * The "GLSL compatibility" code needs a lot of improvements before it is likely to be usable for a nontrivial number of shaders. Some of that work is waiting on Slang compiler fixes, though. * We should consider allowing the individual "toy" effects to define their own uniform parameters and expose those via a UI and reflection. The catch in this case is not that this would be difficult to do, but that it would be a semantic change to how shader toy effects currently work. The Compiler Fixes ------------------ Doing this work exposed a few bugs in Slang, and this change includes fixes for the ones that were quick to address. We already had logic in `slang-check-shader.cpp` that was validating the entry points in a compile request - either by checking the explicitly-listed entry points, or by scanning for `[shader("...")]` attributes. The problem is that the routine that did that checking was not being invoked on all compiles. The logic that handled entry points was only being run for manual compiles using `SlangCompileRequest`, while anything using `import` or `loadModule` would ignore entry points. I refactored the relevant code into a subroutine that will be invoked in all compilation scenarios. There were already `TODO` comments in `SpecializedComponentType` which made the point about how a specialized entry point like `myShader<YourType>` would need to properly show that it has dependencies on both the module that defines `myShader` *and* the module that defines `YourType`, while only the former was being handled at present. I went ahead and implemented the logic to scan the generic arguments for a specialized compoment type in order to determine what module(s) the arguments depend on (both type arguments and witness tables). With that change, using `IComponentType::link` on a specialized component will properly pull in the module(s) that the generic arguments come from. In `slang-ir-legalize-types.cpp` we could run into assertion failures in debug builds because of code trying to legalize layout `IRAttr`s for fields or parameters with types that need legalization. In practice it is safe to skip these layout attributes, because legalization of the fields/parameters they pertain to would result in creation of entirely new layout attributes, and the old ones would then be unreferenced. Future Work (Fixes) ------------------- There are other compiler bugs that this work exposed, but which this change does not address. These will need to be resolved as part of subsequent changes: * Slang allows for default-initialization of variables of a generic type. That is, given `<T : ISomething>` a user is allowed to declare `T x = {};` and the Slang front-end does not complain. Instead, this leads to an internal compiler error during IR lowering. * The Slang `__init()` feature probably needs to be upgraded to a properly supported feature, and we probably need a way to make implementing default-initialization an easy thing (e.g., any `struct` type that has initial-value expressions for all its fields should automatically and implicitly satsify an `init();` requirement declared in an interface) * Iniside an `__init()` definition, code has mutable access to members of the enclosing type, but for some reason the front-end is incorrectly treating `this` as immutable in those contexts. As a result you can write to `someField` but not `this.someField`. * User-defined operator overloads flat out don't work (which isn't surprising given that no clients have decided to use them yet, and we have no test coverage for them). This is actually due to the shadowing rules being used for lookup right now, so a fix for this issue is going to have far-reaching consequences around what overloads are visible where (and anything that impacts overload resolution is a big can of worms, including around performance). * fixup: test case had missing main function

2020-09-23Simplify workflow when using NVAPI (#1556)Tim Foley
In some cases, functionality is available as either a GLSL extension for Vulkan/SPIR-V, or through the NVAPI system for D3D. This situation creates complications because while GLSL extensions are generally all supported by the open-source glslang compiler (which we can bundle and ship), NVAPI operations are exposed through a specific header (`nvHLSLExtns.h`) that ships as part of the NVAPI SDK. When a user wants to explicitly use NVAPI-provided operations in their shader code, there are no major complications for Slang; the user sets up their include paths, `#include`s the relevant header, calls functions in it, and lets Slang deal with the details of compilation. The challenge for Slang arises when we want to provide a cross-platform interface in our standard library (e.g., the `RWByteAddressBuffer.InterlockedAddF32` method that was recently added) that uses either a GLSL extension (when compiling for Vulkan/SPIR-V) or an NVAPI (when compiling to DXBC or DXIL). In that case, the code *generated* by Slang now has a dependency on NVAPI, and we need to somehow emit a `#include` directive that pulls it in when invoking fxc or dxc. Because we do not (and seemingly cannot) bundle the NVAPI header with the compiler, we have to rely on ther user to have it available and to somehow communicate to Slang where it is. Exposing portable routines that sometimes use NVAPI currently creates two main challenges: 1. The user is forced to interact with the "prelude" mechanism in the compiler, which allows the programmer to define code in a given target language that gets prepended to the Slang-generated code. While the prelude mechanism is powerful, it is also hard for users to integrate into their workflow, and our experience so far is that users want something that Just Works. 2. If the user writes code that uses some of our abstract operations that layer on NVAPI *and* they also want to use NVAPI explicitly, they end up with two copies of the NVAPI header (one included by the Slang front-end, and another included by the downstream fxc/dxc compiler). This puts the user in the situation of (a) having to ensure that they set the defines like `NV_SHADER_EXTN_SLOT` consistently both when invoking Slang and when adding their prelude, and (b) even if they do make the definitions consistent, they run into the problem that fxc/dxc complain about overlapping register bindings on the two copies of the `g_NvidiaExt` global shader paraemter that the NVAPI header declares. This change attempts to resolve both issues by adding a lot of "do what I mean" logic to the compiler to try to ease things in the common case. In particular: 1. The user no longer needs to use the "prelude" mechanism when using NVAPI. The compiler now embeds a default prelude for HLSL output, which will `#include` the NVAPI header if and only if the generated code needs NVAPI access because of portable standard library routines that were used. 2. The user can mix-and-match explicit NVAPI use and stdlib functions that compile to use NVAPI. The register/space to be used by NVAPI when included via prelude is now set based on whatever the user set via the preprocessor so that it should automatically be consistent between both cases. Furthermore, the code we emit for the declaration of `g_NvidiaExt` when compiling explicit NVAPI use is set up to be conditional, so that it is skipped in the case where the prelude will pull in its own declaration of that parameter. The way all this is achieved involves a lot of moving pieces: * We now have an HLSL prelude, which mostly just serves to `#include "nvHLSLExtns.h"` in the case where NVAPI support is needed downstream. * Standard library operations that require NVAPI for their implementation on HLSL include a new `[__requiresNVAPI]` attribute. * The preprocessor has been extended so that after tokenizing an input file it looks up the NVAPI-relevant macros in the resulting environment, and if they are set it attached a modifier (`NVAPISlotModifier1) to the AST `ModuleDecl` that is based on their values. Logic is added to detect if multiple input files specify values for the macros in ways that conflict. * The semantic checking step is extended so that it detects the "magic" NVAPI declarations (the `g_NvidiaExt` paramter and the `NvShaderExtnStruct` type that it uses) and attaches a modifier to them so that they can be identified as such in later steps. * Parameter binding is extended to collect a list of the AST modifiers that reflect NVAPI binding, and to reserve the relevant register(s) so that ordinary user-defined parameters cannot conflict with them. * IR lowering translates the three new AST modifiers related to NVAPI over to IR equivalents. * IR linking is extended to make sure that it clones any `IRNVAPISlotDecoration`s attached to the input modules. The pass intentionally does not care where the modifiers came from; it just collects them all and leaves it to downstream code to sort out what they mean. * Emit logic is extended to have a notion of "prelude directives" which are preprocessor directives that should come *before* the prelude in the generated code, because they can impact the way that the prelude compiles. This is done so that we don't have to introduce ad hoc logic for each downstream compiler to set any relevant `-D` flags (e.g., both fxc and dxc would need to duplicate such logic for NVAPI support). * The HLSL source emitter is extended to track whether it emits any operations that require NVAPI support. * The HLSL source emitter is extended to emit prelude directives based on whether NVAPI is needed and, if it is, to also set the register and space that NVAPI should use based on what was stored in the decoration(s) on the IR module. * The HLSL source emitter is extended so that it detects global instructions that represent "magic" NVAPI constructs , and emit them as conditional definitions so that they are skipped when NVAPI is included via the prelude. * The handling of requires capabilities during emit logic was cleaned up a bit so that more logic is shared across targets, and also so that the same logic is used both when emitting a function declaration/definition and when emitting a call to an instrinsic function (which won't get declared/defined).
