This is an update on Fuad's series[1].

Instead of going going back and forth over a series that has seen a
fair few versions, I've opted for simply writing a set of fixes on
top, hopefully greatly simplifying the handling of most registers, and
moving things around to suit my own taste (just because I can).

I won't be reposting the initial 11 patches, which is why this series
in is reply to patch 11.

Thanks for this series. I've reviewed, built it, and tested it with a
dummy protected VM (since we don't have proper protected VMs yet),
which initializes some of the relevant protected VMs metadata as well
as its control registers. So fwiw:

And to whatever extent possible at this stage:

Hi Fuad,

Out of curiosity, when testing pKVM, what VMM do you use? Also, can you
describe what a "dummy pVM" is? Is it a just pVM which is not actually
protected? How similar is a pVM to a typical VIRTIO-using VM? Actually,
maybe I should just ask if there are instructions for playing with pKVM
somewhere that I could get a pointer to.

Thanks,
drew
