x86/tdx is fine.  The KVM convention is to use "KVM: xxx:" for KVM host code and
"x86/kvm" for KVM guest code.  E.g. for KVM TDX host code, the subjects will be
"KVM: x86:", "KVM: VMX:" or "KVM: TDX:".

The one I really don't like is using "tdg_" as the acronym for guest functions.
I find that really confusion and grep-unfriendly.
