73 unlikely. KVM can synthesize the CPUID bit and the KVM guest can simply
74 query CPUID and figure out what the hypervisor supports and what not. As
82 a: Feature flags can be derived from the contents of CPUID leaves.
84 These feature definitions are organized mirroring the layout of CPUID
92 b: Flags can be from scattered CPUID-based features.
94 Hardware features enumerated in sparsely populated CPUID leaves get
95 software-defined values. Still, CPUID needs to be queried to determine
98 checked at runtime in the respective CPUID leaf [EAX=f, ECX=0] bit EDX[1].
100 The intent of scattering CPUID leaves is to not bloat struct
101 cpuinfo_x86.x86_capability[] unnecessarily. For instance, the CPUID leaf
102 [EAX=7, ECX=0] has 30 features and is dense, but the CPUID leaf [EAX=7, EAX=1]
176 Even though the feature will still be detected via CPUID, the kernel disables
