If the WGSL provided over 255 arguments, then we'd overflow the uint8_t,
and a bad candidate could be matched.
We have validation in place to ensure that user functions are not
declared with more than 255 parameters, but no validation for number of
arguments provided.

The WebGPU spec says that a validation error is produced if there is a
color target in the pipeline descriptor that has writeMask!=0 while
there are no shader outputs for this target. In Dawn format==undefined
is used as a tag that the color target is not present, so writeMask is
allowed to be 0 if format==undefined. (the validation in the case where
format!=undefined was already present).

Chromium tracks the devices which live on the wire so it can
automatically call tick on devices that have pending work. This used
to be done by querying an (id, generation) pair and checking if it
resolves to a non-null device.
This CL adds a new way to query directly using the device, since a
refactor in Chrome will change creation such that the id and generation
is not known when a new device is requested.
Also fixes a bug for device callbacks where the required callback
userdata wasn't fully populated for devices created with
requestAdapter. Update a test to check for this as well.

will be switched to errors in a future release.

just show the point at which a uniformity was detected.
In a future release, once we have obtained initial feedback from

There is currently a race condition in the metal backend with the
updating of `mCompletedSerial`. It is currently possible for the
`addCompletedHandler` to set to one value and then have the
`CheckAndUpdateCompletedSerial` call immediately set it back to
a lower value. This can then cause hangs as the serial never
correctly updates again.
This was happening on `dawn.node` when running a large number of
CTS test cases all at the same time.
