<content type='text'>
`GspInitDone` has no payload whatsoever, so the unit type `()` is the
correct way to represent its message content. We can use it now that
`()` implements `FromBytes`.

<title>gpu: nova-core: preserve error information in gpu_name()</title>

<content type='text'>
Change gpu_name() to return a Result instead of an Option. This avoids
silently discarding error information when parsing the GPU name string
from the GSP.

Update the callsite to log a warning with the error details on failure,
rather than just displaying "invalid GPU name".

<title>gpu: nova-core: use CStr::from_bytes_until_nul() and remove util.rs</title>

<id>urn:sha1:da8264ce6c5c02b78f95d31021e942ab38d8dd39</id>
<content type='text'>
The util.rs module contained a single helper function,
str_from_null_terminated(), which duplicated functionality that is now
available in core::ffi::CStr.

Specifically, CStr::from_bytes_until_nul() is available in the kernel's
minimum supported Rust version (1.78.0), so it time to stop using this
custom workaround.

After GSP initialization is complete, retrieve the static configuration
information from GSP-RM. This information includes GPU name, capabilities,
memory configuration, and other properties. On some GPU variants, it is
also required to do this for initialization to complete.

operational and will respond properly to normal RPC commands.

<content type='text'>
Add support for sending the SetRegistry command, which is critical to
GSP initialization.

The RM registry is serialized into a packed format and sent via the
command queue. For now only three parameters which are required to boot
GSP are hardcoded. In the future a kernel module parameter will be added
to enable other parameters to be added.
