I am a bit confused. The DT is only here to tell the guest OP-TEE is
present. But I don't see anything to tell the hypervisor the guest
will use OP-TEE.
Yes, this is what I wanted to discuss. I had a felling that it is not
quite right. I think your idea with DOMCTL is better. I'll rework this
part in the following way:
if there is "optee=1" in a config file, then libxl will create DT
entry and ask hypervisor to enable access to TEE for this domain.
You probably also want to make the variable TEE agnostic by renaming to
"tee".
In the future, the toolstack would need to know which TEE is in used in
the hypervisor. For now, it is fine to assume that it is OP-TEE.
Yes, sounds good. Will do in this way.
Thank you for review and suggestion.
