Skip
`wgpu_test::compute_pass_ownership::compute_pass_resource_ownership`
on the GL backend on AMD Radeon Pro WX 3200, to avoid the kernel crash
described in #5800.
Add the following flags to `wgpu_types::Features`:
- `SHADER_INT64_ATOMIC_ALL_OPS` enables all atomic operations on `atomic<i64>` and
`atomic<u64>` values.
- `SHADER_INT64_ATOMIC_MIN_MAX` is a subset of the above, enabling only
`AtomicFunction::Min` and `AtomicFunction::Max` operations on `atomic<i64>` and
`atomic<u64>` values in the `Storage` address space. These are the only 64-bit
atomic operations available on Metal as of 3.1.
Add corresponding flags to `naga::valid::Capabilities`. These are supported by the
WGSL front end, and all Naga backends.
Platform support:
- On Direct3d 12, in `D3D12_FEATURE_DATA_D3D12_OPTIONS9`, if
`AtomicInt64OnTypedResourceSupported` and `AtomicInt64OnGroupSharedSupported` are
both available, then both wgpu features described above are available.
- On Metal, `SHADER_INT64_ATOMIC_MIN_MAX` is available on Apple9 hardware, and on
hardware that advertises both Apple8 and Mac2 support. This also requires Metal
Shading Language 2.4 or later. Metal does not yet support the more general
`SHADER_INT64_ATOMIC_ALL_OPS`.
- On Vulkan, if the `VK_KHR_shader_atomic_int64` extension is available with both the
`shader_buffer_int64_atomics` and `shader_shared_int64_atomics` features, then both
wgpu features described above are available.

* improve comments based on review feedback
* use the same lifetime name for all usages of `ComputePass<'encoder>`
* comment improvement that I missed earlier
* more review based comment improvements
* use suggested zero-overhead lifetime removal
* rename make_static to forge_lifetime

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.

Use `std::panic::Location` to record the source location of each
`#[gpu_test]` test, and if it fails, include that in the error output.
This is not essential, but it should make working with failures a bit
more comfortable.
Invoke a DeviceLostClosure immediately if set on an invalid device.
To make the device invalid, this defines an explicit, test-only method
make_invalid. It also modifies calls that expect to always retrieve a
valid device.

Rust would have made this operation either an overflow in release mode,
or a panic in debug mode. Neither seem appropriate for this context,
where I suspect an error should be returned instead. Web browsers, for
instance, shouldn't crash simply because of an issue of this nature.
Users may, quite reasonably, have bad arguments to this in early stages
of development!
Fuzz testing in Firefox encountered crashes for calls of
`Global::command_encoder_clear_buffer` where:
* `offset` is greater than `buffer.size`, but…
* `size` is `None`.
Oops! We should _always_ check this (i.e., even when `size` is `None`),
because we have no guarantee that `offset` and the fallback value of
`size` is in bounds. 😅 So, we change validation here to unconditionally
compute `size` and run checks we previously gated behind `if let
Some(size) = size { … }`.
For convenience, the spec. link for this method:
<https://gpuweb.github.io/gpuweb/#dom-gpucommandencoder-clearbuffer>
* [wgpu-core] Add tests for minimum binding size validation.
* [wgpu-core] Compute minimum binding size correctly for arrays.
In early versions of WGSL, `storage` or `uniform` global variables had
to be either structs or runtime-sized arrays. This rule was relaxed,
and now globals can have any type; Naga automatically wraps such
variables in structs when required by the backend shading language.
Under the old rules, whenever wgpu-core saw a `storage` or `uniform`
global variable with an array type, it could assume it was a
runtime-sized array, and take the stride as the minimum binding size.
Under the new rules, wgpu-core must consider fixed-sized and
runtime-sized arrays separately.
This fixes two cases where a DeviceLostClosureC might not be consumed
before it is dropped, which is a requirement:
1) When the closure is replaced, this ensures the to-be-dropped closure
is invoked.
2) When the global is dropped, this ensures that the closure is invoked
before it is dropped.
The first of these two cases is tested in a new test,
DEVICE_LOST_REPLACED_CALLBACK. The second case has a stub,
always-skipped test, DROPPED_GLOBAL_THEN_DEVICE_LOST. The test is
always-skipped because there does not appear to be a way to drop the
global from within a test. Nor is there any other way to reach
Device.prepare_to_die without having first dropping the device.

* 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.
* Remove some locks in BindGroup
These are only written to clear the vectors when triaging bindgroups for destruction, which is not necessary. We can let the reference counts drop when the bind group is dropped.
* Make the mem_leak test pass again
* Keep the value in its storage after destroy
in #4657 the destroy implementation was made to remove the value from the storage and leave an error variant in its place.
Unfortunately this causes some issues with the tracking code which expects the ID to be unregistered after the value has been fully destroyed, even if the latter is not in storage anymore.
To work around that, this commit adds a `Destroyed` variant in storage which keeps the value so that the tracking behavior is preserved while
still making sure that most accesses to the destroyed resource lead to validation errors.
... Except for submitted command buffers that need to be consumed right away. These are replaced with `Element::Error` like before this commit.

* 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.

* 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.
