Join all threads before returning from the test case, to ensure that
we don't return from `main` until all open `Device`s have been
dropped.
This avoids a race condition in glibc in which a thread calling
`dlclose` can unmap a shared library's code even while the main thread
is still running its finalization functions. (See #5084 for details.)
Joining all threads before returning from the test ensures that the
Vulkan loader has finished `dlclose`-ing the Vulkan validation layer
shared library before `main` returns.
Remove `skip` for this test on GL/llvmpipe. With this change, that has
not been observed to crash. Without it, the test crashes within ten
runs or so.
Fixes#5084.
Fixed#4285.
This clarifies that the Rust and C-style callbacks/closures need to be
consumed (not called) before they are dropped. It also makes the from_c
function consume the param closure so that it can be dropped without
panicking.
It also relaxes the restriction that the callback/closure can only be
called once.
* hello_compute: check for missing command-line args
Fixes off-by-one error when checking for missing arguments.
Before this, running the example gave this scary looking error message:
```
$ cargo run --bin wgpu-examples hello_compute
Finished dev [unoptimized + debuginfo] target(s) in 0.13s
Running `target/debug/wgpu-examples hello_compute`
[2023-12-27T22:14:26Z ERROR wgpu::backend::direct] Handling wgpu errors as fatal by default
thread 'main' panicked at 'wgpu error: Validation Error
Caused by:
In Device::create_bind_group
Buffer binding size 0 is less than minimum 4
note: buffer = `Storage Buffer`
', wgpu/src/backend/direct.rs:3139:5
```
As this was the first example I tried to run, it almost scared me
away, thinking it was a driver issue.
Instead, without arguments the example should use defaults.
* Add PR #4939 to changelog as instructed
* Ensure device lost closure is called exactly once before being dropped.
This requires a change to the Rust callback signature, which is now Fn
instead of FnOnce. When the Rust callback or the C closure are dropped,
they will panic if they haven't been called. `device_drop` is changed
to call the closure with a message of "Device dropped." A test is added.
* Introduce `dx12` and `metal` crate features to `wgpu`

* Address review
* Remove `dummy::Context` in favor of `hal::api::Empty`
* Add changelog entry
* Panic early in `Instance::new()` if no backend is enabled

Without the suffix, `Expression::Literal(Literal::F32)` expressions
get written without any suffix on the number, meaning that they get
re-parsed as `AbstractFloat` values. In theory, this should always be
fine, but since we don't actually support abstract types yet in all
the places we should, having them appear in the output causes
validation problems.
See also: #4863, which did the same for `i32` literals.
Without the suffix, `Expression::Literal(Literal::I32)` expressions
get written without any suffix on the decimal number, meaning that
they get re-parsed as AbstractInt values. In theory, this should
always be fine, but since we don't actually support abstract types yet
in all the places we should, having them appear in the output causes
validation problems.
* Make `BufferMappedRange` trait WasmNotSendSync
* make QueueWriteBuffer trait Debug
* add changelog
* fix pr numbers in changelog
* missing send/sync on web.rs on BufferMappedRange for fragile-send-sync-non-atomic-wasm + !atomics
* Downgrade resource lifetime management log level to trace.
Allow promoting it back to info via an feature flag.
* Don't filter out info and warning log in the examples.
* Changelog entry.
Have `compact::compact` preserve entries in the `Module::types` arena
if they have names.
Future abstract type support will require the WGSL front end to
compact the module before validation. Without this change, that will
drop `alias` declarations, making it harder to test type validation.
Previously, implicit padding members of `struct`s were suppressed from
structure definitions in Metal output if they had a binding specified
for them (i.e., `@location(0)`). This padding is, however, is necessary
for correct access of member fields passed into shaders by uniform and
storage buffers. Unconditionally emit padding members for `struct`s.
Resolves
[`gfx-rs/wgpu`#4701](https://github.com/gfx-rs/wgpu/pull/4701).
Let `naga::TypeInner::Matrix` hold a full `Scalar`, with a kind and
byte width, not merely a byte width, to make it possible to represent
matrices of AbstractFloats for WGSL.
Add an `I64` variant to `crate::Literal`, making `crate::Expression`
suitable for representing `AbstractFloat` and `AbstractInt` values in
the WGSL front end.
Make validation reject uses of `Literal::I64` in constant and function
expression arenas unconditionally. Add tests for this.
Let the frontends and backends for languages that have 64-bit integers
read/write them.
Identify reachable function expressions, constant expressions, and
types using a single pass over each arena, taking advantage of the
fact that expressions and types may only refer to other entries that
precede them within their arena. Only walking the statement tree still
requires a worklist/recursion.
In addition to presumably being faster, this change slightly reduces
the number of non-comment lines of code in `src/compact`.
Introduce a new struct type, `Scalar`, combining a `ScalarKind` and a
`Bytes` width, and use this whenever such pairs of values are passed
around.
In particular, use `Scalar` in `TypeInner` variants `Scalar`, `Vector`,
`Atomic`, and `ValuePointer`.
Introduce associated `Scalar` constants `I32`, `U32`, `F32`, `BOOL`
and `F64`, for common cases.
Introduce a helper function `Scalar::float` for constructing `Float`
scalars of a given width, for dealing with `TypeInner::Matrix`, which
only supplies the scalar width of its elements, not a kind.
Introduce helper functions on `Literal` and `TypeInner`, to produce
the `Scalar` describing elements' values.
Use `Scalar` in `wgpu_core::validation::NumericType` as well.
* Better handle destroying textures and buffers
Before this commit, explicitly destroying a texture or a buffer (without dropping it)
schedules the asynchronous destruction of its raw resources but does not actually mark
it as destroyed. This can cause some incorrect behavior, for example mapping a buffer
after destroying it does not cause a validation error (and later panics due to the
map callback being dropped without being called).
This Commit adds `Storage::take_and_mark_destroyed` for use in `destroy` methods.
Since it puts the resource in the error state, other methods properly catch that
the resource is no longer usable when attempting to access it and raise validation
errors.
There are other resource types that require similar treatment and will be addressed
in followup work.
* Add a changelog entry
* More complete implementation of "lose the device".
This provides a way for wgpu-core to specify a callback on "lose the
device". It ensures this callback is called at the appropriate times:
either after device.destroy has empty queues, or on demand from
device.lose.
A test has been added to device.rs.
* Updated CHANGELOG.md.
* Fix conversion to *const c_char.
* Use an allow lint to permit trivial_casts.
* rustfmt changes.
Since the pipeline id is provided by the caller, the caller may presume
that an implicit pipeline layout id is also created, even in error
conditions such as with an invalid device. Since our registry system
will panic if asked to retrieve a pipeline layout id that has never been
registered, it's dangerous to leave that id unregistered. This ensures
that the layout ids also get error values when the pipeline creation
returns an error.
This appears to match other backends, and fixes
fix the case where expressions which were named in earlier
functions are used in local variable declarations
* Add `BGRA8UNORM_STORAGE` extension

* Make buffer_unmap check for device validity, add tests.
This patch makes buffer_unmap check for a valid device, and corrects
buffer_map to return the appropriate error for an invalid device.
Tests are added for both operations.
It also adds device validity checks to device_maintain_ids and to the
functions that get and set buffer sub data.
* Update changelog and test comment.
* Run rustfmt.
* Update test device_lose_then_more to specify more buffer usages to keep Vulkan happy.
* wgpu-core: Only produce StageError::InputNotConsumed on DX11/DX12
This error only exists due to an issue with naga's HLSL support:
https://github.com/gfx-rs/naga/issues/1945
The WGPU spec itself allows vertex shader outputs that are
not consumed by the fragment shader.
Until the issue is fixed, we can allow unconsumed outputs on
all platforms other than DX11/DX12.
* Add Features::SHADER_UNUSED_VERTEX_OUTPUT to allow disabling check
* Pick an unused feature id
Implements timer queries via write_timestamp on Metal for encoders (whenever timer queries are available) and passes (for Intel/AMD GPUs, where we should advertise TIMESTAMP_QUERY_INSIDE_PASSES now).
Due to some bugs in Metal this was a lot harder than expected. I believe the solution is close to optimal with the current restrictions in place. For details see code comments.
Due to an issue with Mesa versions less than 21.2 presentation on Vulkan
was forced to Nvidia only. This in itself brought new issues around the
Nvidia driver specfic format modifers.
As of Mesa 21.2 the Intel vulkan issue is fixed. This commit enables
presentation on versions 21.2 and above for Intel.

explicitly call `vkFreeCommandBuffers` on the `CommandEncoder`'s `free` and
`discarded` lists.

Introduces a DisplayOwner struct to own both the library
and associated display pointer; their lifetimes are combined
in that struct.
The display pointer is encapsulated in a DisplayRef.
When DisplayOwner is dropped, it ensures that the DisplayRef
is correctly closed prior to unloading the library.

As described in [Vulkan-ValidationLayers#5671], the validation layers don't understand debug ranges paired across different command buffers on the same queue, even though the Vulkan spec says:
> An application may open a debug label region in one command buffer and close it in another, or otherwise split debug label regions across multiple command buffers or multiple queue submissions. When viewed from the linear series of submissions to a single queue, the calls to vkCmdBeginDebugUtilsLabelEXT and vkCmdEndDebugUtilsLabelEXT must be matched and balanced.
Until this is fixed, wgpu should ignore this validation error to reduce noise in test runs.
Fixes#3733.

wgpu currently checks if the `write_mask` is 0 to determine wether a
stencil is used as readonly or not. However Webgpu contains a more
complex ruleset that also checks the cull mode and face operations to
determine if the stencil is readonly or not.
This commit brings these new rules to wgpu.
