Because current QEMU x86 CPU definition does not support cache versions, we would have to declare a new CPU type for each such case. To avoid this duplication, the patch allows new cache_info pointers to be specified for a new CPU version.

The only difference vs. older models is an updated cache_info with the 'complex_indexing' bit unset, since this bit is not currently defined for AMD and may cause problems should it be used for something else in the future. Setting this bit will also cause CPUID validation failures when running SEV-SNP guests. Signed-off-by: Michael Roth Signed-off-by: Babu Moger Acked-by: Michael S.

While SSBD (Speculative Store Bypass Disable) disables both PSF and speculative store bypass, PSFD only disables PSF. PSFD may be desirable for the software which is concerned with the speculative behavior of PSF but desires a smaller performance impact than setting SSBD. Depends on the following kernel commit: b73a54321ad8 ("KVM: x86: Expose Predictive Store Forwarding Disable") stibp-always-on : Single Thread Indirect Branch Prediction mode has enhanced performance and may be left always on. The documentation for the features are available in the links below. a. Processor Programming Reference (PPR) for AMD Family 19h Model 01h, Revision B1 Processors b.

The presence of this feature is indicated via the CPUID function 0x8000000A_EDX[25]. automatic-ibrs : The AMD Zen4 core supports a new feature called Automatic IBRS. It is a "set-and-forget" feature that means that, unlike e.g., s/w-toggled SPEC_CTRL.IBRS, h/w manages its IBRS mitigation resources automatically across CPL transitions. The presence of this feature is indicated via the CPUID function 0x80000021_EAX[8]. The documention for the features are available in the links below. a.

The model display for the new processor will be EPYC-Genoa. Adds the following new feature bits on top of the feature bits from the previous generation EPYC models. avx512f : AVX-512 Foundation instruction avx512dq : AVX-512 Doubleword & Quadword Instruction avx512ifma : AVX-512 Integer Fused Multiply Add instruction avx512cd : AVX-512 Conflict Detection instruction avx512bw : AVX-512 Byte and Word Instructions avx512vl : AVX-512 Vector Length Extension Instructions avx512vbmi : AVX-512 Vector Byte Manipulation Instruction avx512_vbmi2 : AVX-512 Additional Vector Byte Manipulation Instruction gfni : AVX-512 Galois Field New Instructions avx512_vnni : AVX-512 Vector Neural Network Instructions avx512_bitalg : AVX-512 Bit Algorithms, add bit algorithms Instructions avx512_vpopcntdq: AVX-512 AVX-512 Vector Population Count Doubleword and Quadword Instructions avx512_bf16 : AVX-512 BFLOAT16 instructions la57 : 57-bit virtual address support (5-level Page Tables) vnmi : Virtual NMI (VNMI) allows the hypervisor to inject the NMI into the guest without using Event Injection mechanism meaning not required to track the guest NMI and intercepting the IRET. auto-ibrs : The AMD Zen4 core supports a new feature called Automatic IBRS. It is a "set-and-forget" feature that means that, unlike e.g., s/w-toggled SPEC_CTRL.IBRS, h/w manages its IBRS mitigation resources automatically across CPL transitions.
