* Change the signature of `wgpu_core::Global::queue_submit` to return
a `(SubmissionIndex, …)` in addition to its current error type.
* Change the control flow of errors in `Queue::submit` to break to the
end of a block. This is similar to what we already do in many APIs in
`wgpu_core`.
* Hoist the scope of the local `submit_index` binding so it can be used
at the point where we need to convert current error paths to also
return the submission index.
Later, we will likely want to avoid actually retrieving a new submission
index so we can minimize the critical section of code. We'll need to
figure out a strategy for returning a valid (but not necessarily unique)
index in the case of failures that prevent successful submission.
This is just an API change for all the "set_bind_group" calls. Calls
that pass a Some() argument should have unchanged behavior. The None
cases are left as TODOs.
This option was only evaluated for Metal backends, and now it's required
there so the option is going away. It is still configurable for tests
via the PipelineOptions struct, deserialized from .ron files.
This also fixes some type problems with the unpack functions in
writer.rs. Metal << operator extends operand to int-sized, which then
has to be cast back down to the real size before as_type bit conversion.
The math for the snorm values is corrected, in some cases using the
metal unpack_snorm2x16_to_float function because we can't directly
cast a bit-shifted ushort value to half.
* Expose gpu allocation configuration options
This commit adds hints to control memory allocations strategies to the configuration options. These hints allow for automatic profiles such as optimizing for performance (the default, makes sense for a game), optimizing for memory usage (typically more useful for a web browser or UI library) and specifying settings manually.
The details of gpu allocation are still in flux. The goal is to switch vulkan and metal to gpu_allocator which is currently used with d3d12. gpu_allocator will also likely receive more configuration options, in particular the ability to start with smaller memory block sizes and progressively grow the block size. So the manual settings already provision for this upcoming option. Another approach could be to wait and add the manual option after the dust settles.
The reason for providing presets and defining values in the backends is that I am convinced that optimal fonigurations should take hardware capabilities into consideration. It's a deep rabbithole, though, so that will be an exercise for later.

* Allow unconsumed inputs in fragment shaders by removing them from vertex
outputs when generating HLSL.
Fixes https://github.com/gfx-rs/wgpu/issues/3748
* Add naga:🔙:hlsl::FragmentEntryPoint for providing information
about the fragment entry point when generating vertex entry points via
naga:🔙:hlsl::Writer::write. Vertex outputs not consumed by the
fragment entry point are omitted in the final output struct.
* Add naga snapshot test for this new feature,
* Remove Features::SHADER_UNUSED_VERTEX_OUTPUT,
StageError::InputNotConsumed, and associated validation logic.
* Make wgpu dx12 backend pass fragment shader info when generating
vertex HLSL.
* Add wgpu regression test for allowing unconsumed inputs.
* Address review
* Add note that nesting structs for the inter-stage interface can't
happen.
* Remove new TODO notes (some addressed and some transferred to an issue
https://github.com/gfx-rs/wgpu/issues/5577)
* Changed issue that regression test refers to 3748 -> 5553
* Add debug_assert that binding.is_some() in hlsl writer
* Fix typos caught in CI
Also, fix compiling snapshot test when hlsl-out feature is not enabled.
* share timestamp write struct
* Make name of set_push_constants methods consistently plural
* remove lifetime bounds of resources passed into render pass
* first render pass resource ownership test
* introduce dynrenderpass & immediately create ArcCommands and take ownership of resources passed on pass creation
* Use of dynrenderpass in deno
* Separate active occlusion & pipeline statitics query
* resolve render/compute command is now behind `replay` feature
* add vertex & index buffer to ownership test
* test for pipeline statistics query
* add occlusion query set to pass resource test
* add tests for resource ownership of render pass query timestamps
* RenderPass can now be made 'static just like ComputePass. Add respective test
* Extend encoder_operations_fail_while_pass_alive test to also check encoder locking errors with render passes
* improve changelog entry on lifetime bounds
This proves a flag in msl::PipelineOptions that attempts to write all
Metal vertex entry points to use a vertex pulling technique. It does
this by:
1) Forcing the _buffer_sizes structure to be generated for all vertex
entry points. The structure has additional buffer_size members that
contain the byte sizes of the vertex buffers.
2) Adding new args to vertex entry points for the vertex id and/or
the instance id and for the bound buffers. If there is an existing
@builtin(vertex_index) or @builtin(instance_index) param, then no
duplicate arg is created.
3) Adding code at the beginning of the function for vertex entry points
to compare the vertex id or instance id against the lengths of all the
bound buffers, and force an early-exit if the bounds are violated.
4) Extracting the raw bytes from the vertex buffer(s) and unpacking
those bytes into the bound attributes with the expected types.
5) Replacing the varyings input and instead using the unpacked
attributes to fill any structs-as-args that are rebuilt in the entry
point.
A new naga test is added which exercises this flag and demonstrates the
effect of the transform. The msl generated by this test passes
validation.
Eventually this transformation will be the default, always-on behavior
for Metal pipelines, though the flag may remain so that naga
translation tests can be run with and without the tranformation.
* lift encoder->computepass lifetime constraint and add now failing test
* compute passes now take an arc to their parent command encoder, thus removing compile time dependency to it
* Command encoder goes now into locked state while compute pass is open
* changelog entry
* share most of the code between get_encoder and lock_encoder
* rename `command_encoder_run_*_pass` to `*_pass_end` and make it a method of compute/render pass instead of encoder
* executing a compute pass consumes it now such that it can't be executed again
* use handle_error instead of handle_error_nolabel for wgpu compute pass
* use handle_error instead of handle_error_nolabel for render_pass_end
* changelog addition
* feat: `compute_pass_set_push_constant`: move panics to error variants
