The SRO model covers more details than the pkvm_hyp_req infrastructure.
Should we look at making the two more similar?

Thanks for the pointer.

Where I'd expect CCA and pKVM to converge is how confidential
computing platforms are abstracted to the rest of the kernel, and that
already happens: arm-cca-guest and pkvm-guest sit side by side. The
host to hypervisor path seems like a different question to me.

Cheers,

Hum, this is really just a few lines of code. Also, pKVM doesn't need a stable
ABI with the kernel. Implementing a portion of a spec here sounds way too
complicated for that simple usage IMO. I struggle to see in what way this would
make pKVM better.
