The HviGetHypervisorInterface function obtains the output of a hypervisor’s cpuid leaf 0x40000001.
VOID HviGetHypervisorInterface (HV_HYPERVISOR_INTERFACE_INFO *);
The one argument provides the address of a structure that is to receive the cpuid output.
The HviGetHypervisorInterface function is exported by name from the kernel in version 10.0 and higher.
The HviGetHypervisorInterface function is not documented.
If cpuid leaf 1 shows that a hypervisor is present—see HviIsAnyHypervisorPresent—then the function copies to the given address whatever cpuid leaf 0x40000001 produces in the eax, ebx, ecx and edx registers.
Otherwise, the structure at the given address is zeroed.
