Add bindings and accessors used for the GSP command queue.
Signed-off-by: Alistair Popple <apopple@nvidia.com>
---
Changes for v5:
- Derive the Zeroable trait for structs and enums
Changes for v4:
- Don't panic the kernel if trying to initialise a large (> 4GB)
message header.
- Use `init!` to provide safe and complete initialisers.
- Take an enum type instead of a u32 for the function.
Changes for v3:
- New for v3

There are lots of unused warnings when building on this commit. I know
we don't like big patches, but since this is semantically related to the
next one and the two touch different files anyway, how about merging
them? IMHO this is preferable to adding lots of `#[expect(unused)]` that
we are going to remove right after.
If you have been told to split in a previous version, let's just add a
the `#[expect(unused)]` where needed.

Can we split functions and events into distinct types? Their bindings
even have different prefixes.
Also, rather than casting these all as `isize`, I'd suggest making the
type `#[repr(u32)]`. We don't need negative values here.

Let's resolve this TODO by declaring a constant or even better,
adding the relevant bindings symbol if there is one.

This `as` is ok once we set `MsgFunction` to have a `u32`
representation, but...
> + length: (size_of::<Self>() as u32)
... at the risk of sounding too pedantic, we probably want to do the
arithmetic on the `usize`, and then do a `try_into` u32 to remove this
use of `as` here:
length: size_of::<Self>()
.checked_add(cmd_size)
.ok_or(EOVERFLOW)
.and_then(|v| v.try_into().map_err(|_| EINVAL))?,
This also requires changing the `cmd_size` to `usize`, which is actually
better as that's also the type used by the caller anyway, so this
removes another conversion.

We can save ourselves a bunch of `as` conversions in the following patch
if we make this method just return `usize`. The only one needed will be
for `self.inner.rpc.length` to `usize`, we really ought to have
non-fallible converters for things like this that obviously cannot fail.

Documentation needed for these too.

A possible middle-ground is to add the `expect` in a "more global" position, e.g. at the top, so that it is a single line change. I think that is fine as long as it is removed right after. Thanks!

No, I just split it here because it seemed like a nice self-contained thing. That and I'm conditioned to linux-mm patches where 20 changes is often considered a big patch :-) So I will probably just squash this as suggested. > > A possible middle-ground is to add the `expect` in a "more global" > position, e.g. at the top, so that it is a single line change.
