Functions

adjust_cpuid

Adjust a CPUID instruction result to return values that work with crosvm.

cpu_manufacturer

filter_cpuid

Adjust all the entries in cpuid based on crosvm’s cpuid logic and ctx. Calls adjust_cpuid on each entry in cpuid, and adds any entries that should exist and are missing from cpuid.

setup_cpuid

Sets up the cpuid entries for the given vcpu. Can fail if there are too many CPUs specified or if an ioctl returns an error.
