For TDX, there is an RFC relating to using descriptively named parameters instead of register names for tdh_vp_enter(): https://lore.kernel.org/all/fa817f29-e3ba-4c54-8600-e28cf6ab1953@xxxxxxxxx/ Please do give some feedback on that approach. Note we need both KVM and x86 maintainer approval for SEAMCALL wrappers like tdh_vp_enter(). As proposed, that ends up with putting the values back into vcpu->arch.regs[] for __kvm_emulate_hypercall() which is not pretty:
If needed we can revert this patch, it's not a big problem. Paolo
