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.
