Ok, I'm less surprised now, but it means the test didn't provide the
information I was after :-(

I don't really know what needs to be done to get NOVA_CORE enabled.
Presumably having all the required pieces of rust is a prerequisite.

Me, I haven't been able to get even rust/kernel/firmware.rs to compile:
'make rustavailable' at the top level should tell whether you have all
it takes.  So I don't really know what to expect, but I'd think that
without that you won't be able to enable any rust modules in the kernel
config.

NOVA_CORE depends on:

       depends on PCI
       depends on RUST
       depends on RUST_FW_LOADER_ABSTRACTIONS

RUST_FW_LOADER_ABSTRACTIONS presumably requires bindgen.

But it also defaults to 'n', so yes, you'd need to enable it explicitly
to get it built.

I don't think it's in the repo, but it's not relevant for this pursuit:
NOVA_CORE is new in 6.15, and rpmfreedom doesn't have 6.15 yet.

No, Freed-ora used to do that, but it has been discontinued.
