RH-Commit: [54/115] 01b560fa024020f7be4e649cabd47f9f6bca920a (bonzini/rhel-qemu-kvm)
|
|
|
|
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.
