Yah, coming up with a proper name here hasn't been easy.
prot_guest_has() is not the first variant.

From all three things you suggest above, I guess calling it a "platform"
is the closest. As in, this is a confidential computing platform which
provides host and guest facilities etc.

So calling it

confidential_computing_platform_has()

is obviously too long.

ccp_has() clashes with the namespace of drivers/crypto/ccp/ which is
used by the technology too.

coco_platform_has() is too unserious.

So I guess

cc_platform_has()

ain't all that bad.

Unless you have a better idea, ofc.
