pub fn check_host_cpuid(
host: &dyn HostCpuid,
advertised: &[(u32, u32, usize, u32)],
) -> Result<(), AdmissionRefusal>Expand description
The host checks that need only CPUID, in the order they are checked:
every advertised v3 feature bit natively, OSXSAVE, not a hybrid part, and
not an AMD part without XSAVEERPTR (where Linux runs fnclex; emms; fildl
before every FPU restore, a path no host here can exercise).
