b38b0f
New CPU models mostly inherit features from ancestor Skylake-Server,
b38b0f
while addin new features: AVX512_VNNI, Intel PT.
b38b0f
SSBD support for speculative execution
b38b0f
side channel mitigations.

Note:
b38b0f
b38b0f
On Cascadelake, some capabilities (RDCL_NO, IBRS_ALL, RSBA,
b38b0f
SKIP_L1DFL_VMENTRY and SSB_NO) are enumerated by MSR.
b38b0f
These features rely on MSR based feature support patch.
b38b0f
Will be added later after that patch's in.
