esolutions like
1080x1920, which require stride padding to a multiple of 64 bytes.
In principle, this could be extended to support the V4L2 multiplanar
API, though there seem to be practically no capture (not M2M) drivers
that support this, so it's not terribly useful right now.

This shouldn't regress any existing drivers, since calling
drm_sched_fini() with any pending jobs is broken and this change should
be a no-op if there are no pending jobs.

After a job is pushed into the queue, it is owned by the scheduler core
and may be freed at any time, so we can't write nor read the submit

That was supposed to have Markdown-style section headings, but I forgot
that b4 considers a leading # as a comment... sorry for the abrupt topic
changes...
The intended headings are below.

This macro allows Rust code to build multiple versions of the same code,
conditionally including certain fields or code segments.
The asahi driver uses this to support multiple GPU types and firmware
revisions in the same codebase, without duplicating everything.

Add the Asahi UAPI to bindings_helper.h so Rust code can use it.

Adds the Asahi GPU driver UAPI. Note: this API is not yet stable and
therefore not ready for merging!

The GPU scheduler manages scheduling GPU jobs and dependencies between
them. This Rust abstraction allows Rust DRM drivers to use this
functionality.

abstraction for
drm_sched, without having to externally duplicate the tracking of
in-flight jobs.
This shouldn't regress any existing drivers, since calling
drm_sched_fini() with any pending jobs is broken and this change should
be a no-op if there are no pending jobs.

Some hardware may require more complex resource utilization accounting
than the simple job count supported by drm_sched internally. Add a
can_run_job callback to allow drivers to implement more logic before
deciding whether to run a GPU job.

The DRM shmem helper includes common code useful for drivers which
allocate GEM objects as anonymous shmem. Add a Rust abstraction for
this. Drivers can choose the raw GEM implementation or the shmem layer,
depending on their needs.

There doesn't seem to be a way for the Rust bindings to get a
compile-time constant reference to drm_gem_shmem_vm_ops, so we need to
duplicate that structure in Rust... this isn't nice...

Add the initial abstractions for DRM drivers and devices. These go
together in one commit since they are fairly tightly coupled types.
A few things have been stubbed out, to be implemented as further bits of
the DRM subsystem are introduced.
