This change originated as an attempt to re-enable a test case, but it has ended up disabling more tests (for good reasons) than it re-enables.
The main change here is a significant overhaul of the way that the D3D12 render path extracts information from the Slang reflection API to produce a root signature.
There were also some supporting fixes in the reflection information to make sure it returns what the D3D12 back-end needed.
The big picture here is that the D3D12 path now uses the descriptor ranges stored in the reflection data more or less directly.
It still needs to use register/space offset information queried via the "old" reflection API, but it only does so at the top level now, for the program and entry points themselves.
All other layout information is derived directly from what Slang provides.
Smaller changes:
* The "flat" reflection API was expanded to include `getBindingRangeDescriptorRangeCount()` which was clearly missing.
* The "flat" reflection results for a constant buffer or parameter block that didn't contain any uniform data and was mapped to a plain constant buffer needed to be fixed up. That logic is still way to subtle to be trusted.
* Several additional tests were disabled that relied on static specialization, global/entry-point generi type parameters, structured buffers of interfaces or other features we don't officially support with shader objects right now. All of the affected tests were somehow passing by sheer luck and because they often passed in specialization arguments via explicit `TEST_INPUT` lines.
* The `inteface-shader-param` test is re-enabled now that we can properly describe its input with the new `set` mode on `TEST_INPUT`
* `ShaderCursor::getElement()` can now be used on structure types (in addition to arrays) to support by-index access to fields
* The `TEST_INPUT` system was expanded to support both by-name and by-index setting of structure fields for aggregates
* The `TEST_INPUT` system was expanded to allow an `out` prefix to mark parts of an expression as outputs on a `set` lines
* The `TEST_INPUT` system was expanded so that anything that would be allowed on a `TEST_INPUT` line by itself (like `ubuffer(...)`) can now be used as a sub-expression on a `set` line

This change allows the `TEST_INPUT` syntax used by `render-test` to support aggregate values with a single input line more easily.
The test writer can now use a syntax like:
```
//TEST_INPUT:set someVar = 3.0
```
Input lines that start with the `set` keyword will now use a simpler `dst = src` format (instead of `dst:name=src` as the existing syntax used). The right-hand side expression can include:
* Numeric literals, both integer and floating-point (currently only supporting 32-bit scalar types; we could fix this later)
* Arrays, consisting of zero or more comma-separated expressions inside `[]`
* Aggregates, consisting of zero or more comma-separated "fields" inside `{}`. A field can either be `name: <expr>` or just `<expr>`
* Objects, which can be written as either `new SomeType{ <fields> }` or `new{ <fields> }` in the case where the type is know-able from context
With this approach is should be possible to support almost arbitrary-type inputs on a single line. For now, I have used this support to re-enable an existing test that had been disabled due to lack of support for setting up arrays of objects.
Major things left to do:
* The new syntax doesn't support the existing cases we had for `Texture2D`, etc. Those should probably be supported but I'd like to find a way to do it without duplicating the parsing logic (ideally the value cases from the existing code should Just Work in the new model)
* There is no support right now for non-32-bit scalar types
* It would be good if this support (and the shader cursor system) supported treating vectors like aggregates
* The actual value-setting logic doesn't currently handle aggregates without field names, so `{ a:0, b:1 }` will work but `{ 0, 1 }` will parse but fail when it comes time to set values
* While this approach lets complicated values be set with a single line, that isn't always what a user will want to do: in the future we should provide a way to break up an aggregate value over multiple lines that is consistent with this approach
* Once we port all of the relvant tests over, it would be great to drop the `set` prefix and have these lines look as simple and conventional as possible

The original goal of this change was to streamline the `TEST_INPUT` system by eliminating options that are no longer relevant once we have eliminated the non-shader-object execution paths. The result is more or less a re-implementation/refactor of the logic around how input is parsed and represented, that tries to set things up for a more general sytem going forward.
The main changes isthat the `ShaderInputLayout` no longer tracks a simple flat list of `ShaderInputLayoutEntry` (that is a kind of pseudo-union of the various buffer/texture/value cases), and it instead uses a hierarchical representation composed of `RefObject`-derived classes to represent "values."
There are several "simple" cases of values
* Textures
* Samplers
* Uniform/ordinary data (`uniform`)
* Buffers composed of uniform/ordinary data (`ubuffer`)
Then there are composed/aggregate values that nest other values:
* An *aggregate* value is a set of *fields* which are name/value pairs. It can be used to fill in a structure, for example.
* An *array* value is a list of values for the elements of an array. It can be used to fill out an array-of-textures parameter, for example.
* A combined texture/sampler value is a pair of a texture value and a sampler value (easy enough)
* An *object* holds an optional type name for a shader object to allocate (it defaults to the type that is "under" the current shader cursor when binding), and a nested value that describes how to fill in the contents of that object
Finally there are cases of values that are just syntactic sugar:
* A `cbuffer` is just shorthand for creating an object value with a nested uniform/ordinary data value
The big idea with this recursive structure is that it gives us a way to handle more arbitrary data types with name-based binding. Supporting this new capability requires changes to both how input layouts get parsed, and also how they get bound into shader objects.
On the parsing side, things have been refactored a bit so that parsing isn't a single monolithic routine. The refactor also tries to make it so that the various options on an input item (e.g., the `size=...` option for textures) are only supported on the relevant type of entry (so you can't specify as many useless options that will be ignored).
The bigger change to parsing is that it now supports a hierarchical structure, where certain input elements like `begin_array` can push a new "parent" value onto a stack, and subsequent `TEST_INPUT` lines will be parsed as children of that item until a matching `end` item. This approach means that we can now in principle describe arbitrary hierarchical structures as part of test input without endlessly increasing the complexity of invididual `TEST_INPUT` lines.
On the binding side, we now have a central recursive operation called `assign(ShaderCursor, ShaderInputLayout::ValPtr)` that assigns from a parsed `ShaderInputLayout` value to a particular cursor. That operation can then recurse on the fields/elements/contents of whatever the cursor points to.
Major open directions:
* With this change it is still necessary to use `uniform` entries to set things like individual integers or `float`s and that is a little silly. It would be good to have some streamlines cases for setting individual scalar values.
* Further, once we have a hierarchical representation of the values for `TEST_INPUT` lines, it becomes clear that we really ought to move to a format more like `TEST_INPUT: dstLocation = srcValue;` where `srcValue` is some kind of hierarchial expression grammar. Refactoring things in this way should make the binding logic even more clear and easy to understand. The refactored parser should make parsing hierarchical expressions easier to do in the future (even if it uses the push/pop model for now)
* One detailed note is that the representation of buffers in this change is kind of a compromise. Just as an "object" value is a thin wrapper around a recursively-contained value for its "content" it seems clear that a buffer could be represented as a wrapper around a content value that could include hierarchical aggregates/objects instead of just flat binary data (this would be important for things like a buffer over a structure type that lays out different on different targets). The main problem right now with changing the representation is actually needing to compute the size of a buffer based on its content, so that can/should be addressed in a subsequent change.
Details:
* The base `RenderTestApp` class and the `ShaderObjectRenderTestApp` classes have been merged, since the hierarchy no longer serves any purpose.
* Disabled the tess that rely on `StructuredBuffer<IWhatever>` because they aren't really supported by our current shader object implementation
* Replaced used of `Uniform` and `root_constants` in `TEST_INPUT` lines with just `uniform`
* Removed a bunch of uses of `stride` from `cbuffer` inputs, where it wasn't really correct/meaningful
* Added the `copyBuffer()` operation to VK/D3D renderers, along with some missing `Usage` cases to support it.
* Made `ShaderCursor` handle the logic to look up a name in the entry points of a root shader object, rather than just having that logic in `render-test`. (We probably need to make a clear design choice on this issue)

* Improve Vulkan shader-objects implementation.
1. Null bindings no longer crashes.
2. No longer copies push constants to staging CPU buffer before setting it into command buffer. The entry-point shader object now directly sets it into command buffer upon `bindObject` call.
* Update comments
* Fix
* Re-enable 3 tests.
Improved vulkan implementation so that each shader object is responsible for creating descriptor sets on-demand.
Fixed slang reflection to correctly report `ParameterBlock` binding.
* Fix gcc compile error.

|
* Reimplement Vulkan shader objects.
This change reimplements Vulkan shader objects in the `gfx` layer so that it is no longer layered on top of the `DescriptorSet` abstraction. Since this is the last implementation that uses `DescriptorSet`, the change also removes all `DescriptorSet` related API from public `gfx` interface.
The Vulkan implementation now passes all test cases, but it still have two issues:
1. The PushConstant setting is not correct, this is because we don't seem to be able to get correct reflection data about the size of push constants for an entry-point.
2. The `shader-toy` example can't run on Vulkan, because it currently sets nullptr to `Texture` bindings, and this change doesn't properly handle setting resource to null in `ShaderObject`s yet. If we can use the `nullDescriptor` feature on vulkan, this implementation will be simple. However we still want to decide whether we want to use a Vulkan 1.2 feature for this.

* 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).

* 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

* Change representation of initial data for textures
Before this change, initial data for a texture has been provided with the `ITextureResource::Data` type, where a call to `IDevice::createTexture()` would take zero or one `Data` and, if present, use it to initialize all the subresources of a texture.
The organization of `Data` was not actually quite how its own documentation comment described it (the implementations didn't agree with the comment), and while it aggressively factored out redundancies (e.g., only storing the stride for each mip level once, instead of once per subresource for large arrays), the result was that setting up a `Data` correcty was a bit confusing.
This change makes the initial data for a texture using a `SubresourceData` type that is almost identical to what D3D11 uses, so that developers are more likely to be comfortable filling it in. All of the existing implementations were easily adapted to use the new type, so it seems like a net win.
Note: Both Vulkan and D3D11 do away with the idea of initializing a texture with data as part of allocating it, and we might eventually want to do the same given the complexity that this system entails. The main reason to preserve this detail is for better compatibility with D3D11, where immutable textures/buffers need to have their data specified at creation time. It seems good to preserve the ability to have immutable resources on target APIs where this distinction could affect performance (e.g., immutable resources do not need state/transition tracking on APIs like D3D11).

* Shader object specialization work-in-progress
The big change here is in the `setObject()` implementations, where we now take write the witness table ID and data for the value being assigned in both the CUDA and graphics-API paths (it is possible the code could be shared...). The logic for deciding whether a value "fits" in the existential value payload should actually be correct here, since it uses the reflection data.
The other relevant change is that the logic for writing out the ordinary/uniform data for a shader object on the graphics-API path has been updated so that it only allocates the GPU buffer *after* it knows the specialized layout, and can thus allocate space for any extra parameter data that wasn't in the original layout but got added by specialization. There is some inactive code in place that tries to sketch how the implementation should handle writing the data of sub-objects for interface-type fields into the appropriate areas of the allocated buffer for a parent object, but that is stubbed out for now pending implementation of the relevant reflection information.
This change also introduces logic in the graphics-API path to create a specialized layout for a shader object on-demand (so that it will only be created after the specialization arguments are known or can be inferred). The implementation needs to treat ordinary shader objects and root shader objects differently because the Slang API handles specialization differently for ordinary types vs. `IComponentType`s.
Some notes and caveats:
* The CUDA path doesn't need to compute specialized layouts the way the graphics-API path does because layout doesn't change based on specialization for that path (just as it won't for the CPU path)
* This code just skips over the RTTI field in existential values because it seems that we currently aren't using it in generated code.
* We are completely missing the logic for recursively writing the resource ranges of sub-objects bound to interface-type fields into the descriptor set(s) of the parent object. The missing link there is reflection API support, just as it is for filling in the ordinary/uniform data. We need a way to get the binding range offset (and binding array stride) for the "pending" data of a specialized interface-type field.
* The logic for computing specialization arguments based on the shader objects bound to interface-type fields has a lot of holes. Some of the indexing math is flat-out incorrect, and it also doesn't make any attempt to handle sub-object ranges with more than one element in them. I tweaked some of the code there to make it *more* correct, but that doesn't mean it is actually correct at this point.
* The logic for computing a specialized `IComponentType` for a `ProgramVars` in the graphics-API path seems to have a lot of overlap with `maybeSpecializeProgram()`, so we should look into ways to avoid the duplication over time.

This change kind of rolls together two different simplifications:
1. The `createShaderObject()` shouldn't really need to take an `IShaderObjectLayout` because it could just take the `slang::TypeLayoutReflection` instead and create the shader-object layout behind the scenes.
2. For that matter, it needn't take a `slang::TypeLayoutReflection` either, becaues it could just take a `slang::TypeReflection` and query the layout of that type behind the scenes.
The combination of these two changes means:
* `IShaderObjectLayout` is gone from the public API, as is `createShaderObjectLayout()`
* `createShaderObject()` directly takes a `slang::TypeReflection` and allocates a shader object of that type
The result is simpler and more streamlined application code.
Note that under the hood the implementation still has shader-object layouts, using the `ShaderObjectLayoutBase` class. A few locations had to change to use `RefPtr`s instead of `ComPtr`s now that the class is no longer a public COM-lite API type.
The hope is that this change makes it easier to allocate/cache layouts for things like specialized types "under the hood," as is needed to implement parameter setting for static specialization.
|
|
This change makes it so that the shared shader object implementation across graphics APIs (everything except CUDA and CPU) uses a host-memory buffer to store ordinary (aka "uniform") data while the shader object is being set up / modified, and then allocates and initializes a GPU-memory buffer for the data on-demand once setup is complete.
This choice is a necessary step for supporting interface/existential-type fields in the presence of static specialization, because any fixed-size GPU buffer we would try to allocate at the time an object is first created might not turn out to be large enough if static specialization must handle a concrete type that doesn't "fit" into the fixed-size space reserved for an existential value (resulting in the value having to be placed in an overflow region outside the original object).
This change does *not* include any of the work related to actually laying out existential-type fields in this fashion. It instead just focuses on changing when and where the GPU memory allocation is performed to one that is more appropriate for those subsequent changes.

The purpose of these changes is to make the `shader-object` example work correctly on CUDA.
Originally I had tried to add changes to the "flat" reflection information so that it introduced descriptor ranges to match the binding ranges it added for interface/existential-type fields. This approach helped the CUDA code that was using that information to try and compute uniform offsets for those fields, but it broke most of the other renderer back-ends. Instead, I removed the relevant asserts from `CUDAShaderObject::setObject()`.
Note taht there are leftover changes from my edits to the flat reflection information, around how it handles "leaf" fields that consume multiple resource kinds. I believe that those changes are, on balance, "more correct" now than they were before, so I decided to leave them in.
The other major fix here is to specialize the `CUDAShaderObject::setObject()` logic to handle the case of setting a shader object for a parameter that has interface type instead of a constant-buffer or parameter block. Mostly I just copy bytes from the child object into the parent object. There are a few caveats, though:
* I am not writing the RTTI or witness-table information, so dynamic dispatch won't work.
* I am assuming a hard-coded offset of 16 bytes for the any-value, which will work for now but is a bit too "magical" and might also break once we support conjunctions of interfaces with dynamic dispatch
* I am assuming that the child value to be writen into the field will "fit" into the any-value area. We need some way to determine whether or not things fit dynamically (ideally using the reflection data), and adapt accordingly.
* I had to add another method on the base CUDA shader object type to handle setting data using a device-memory pointr instead of a host-memory pointer
* There's not a lot we can do about it, but in the case of assigning an ordinary `CUDAShaderObject` into an interface-type field of a `CUDAEntryPointShaderObject` we end up needing to perform a device->host memory copy, because the bytes of the value will have already been written to GPU memory, but need to be in GPU memory for the dispatch call.
* The implementation I'm using here basically assumes that the child shader object must have been finalized before it gets plugged into the parent shader object. We haven't yet made a policy decision about that bit.

* Use Index for StringUtil.
* WIP: First pass support for parsing Slang diagnostics.
* WIP Testing comparing with ParseDiagnosticUtil with previous ad-hoc mechanism.
* Use the new parsing mechanism for diagnostic comparisons.
* Fix layout on GLSL, doesn't have CR so runs into main.
* Split out switch on outputting intrinsic 'specials'.
Output code around intrinsic as emit - so that we get the appropriate indenting (and potentially other benefits).
* Improvements to diagnostics parsing.
Better error handling, and fallback handling.
Added ability to parse downstream compilers without a prefix.
Added ability to parse Slang with a prefix.
* DownstreamDiagnostic::Type -> Severity and related fixes.
* Small fixes around moving from DownstreamDiagnostic::Type -> Severity
* Fix handling of 'special intrinsic' expansion
* Split out the handling of intrinsic expansion into it's own type and files.
* Fixes to reading expected output - for SimpleLine test.
* Test using += to check #line output.
* A test around += and return.
* Small comment fixes.

* #include an absolute path didn't work - because paths were taken to always be relative.
* WIP diagnostics for line number output.
* Small param naming change
* Use x macro for pass through compile human name lookup/getting.
* WIP on parsing downstream compiler output.
* Split out parsing into ParseDiagnosticUtil.
Added test result of single line.
