Expand description

CPUID entry information stored for each leaf of IntelCpuid.

Fields§

§flags: KvmCpuidFlags

The KVM requires a flags parameter which indicates if a given CPUID leaf has sub-leaves. This does not change at runtime so we can save memory by not storing this under every sub-leaf and instead fetching from a map when converting back to the KVM CPUID structure. But for robustness we currently do store we do not use this approach.

A map on flags would look like:

ⓘ
#[allow(clippy::non_ascii_literal)]
pub static KVM_CPUID_LEAF_FLAGS: phf::Map<u32, KvmCpuidFlags> = phf::phf_map! {
    0x00u32 => KvmCpuidFlags::EMPTY,
