Let's prepare the API for nested SVM too. Please rename it to
KVM_CAP/GET/SET_NESTED_STATE and let's organize it like this:
/* In addition to guest mode and run pending, please
* add one for GIF.
*/
__u16 flags;
/* 0 for VMX, 1 for SVM. */
__u16 format;
/* 128 for SVM, 128 + VMCS size for VMX. */
__u32 size;
/* Both structs padded to 120 bytes. */
union {
/* VMXON, VMCS */
struct kvm_vmx_state vmx;
/* HSAVE_PA, VMCB */
struct kvm_svm_state svm;
}
__u8 data[0];
David, would the above make sense for s390 nested SIE too?
Thanks,
Paolo
