[PATCH v2 38/58] i386/tdx: Call KVM_TDX_INIT_VCPU to initialize TDX vcpu |
Date: |
Fri, 18 Aug 2023 05:50:21 -0400 |
TDX vcpu needs to be initialized by SEAMCALL(TDH.VP.INIT) and KVM
provides vcpu level IOCTL KVM_TDX_INIT_VCPU for it.
KVM_TDX_INIT_VCPU needs the address of the HOB as input. Invoke it for
each vcpu after HOB list is created.
