Adds the support for 2nd Gen AMD EPYC Processors. The model display name will be EPYC-Rome. Adds the following new feature bits on top of the feature bits from the first generation EPYC models. perfctr-core : core performance counter extensions support. Enables the VM to use extended performance counter support. It enables six programmable counters instead of four counters. clzero : instruction zeroes out the 64 byte cache line specified in RAX. xsaveerptr : XSAVE, XSAVE, FXSAVEOPT, XSAVEC, XSAVES always save error pointers and FXRSTOR, XRSTOR, XRSTORS always restore error pointers. wbnoinvd : Write back and do not invalidate cache ibpb : Indirect Branch Prediction Barrier amd-stibp : Single Thread Indirect Branch Predictor clwb : Cache Line Write Back and Retain xsaves : XSAVES, XRSTORS and IA32_XSS support rdpid : Read Processor ID instruction support umip : User-Mode Instruction Prevention support The Reference documents are available at https://developer.amd.com/wp-content/resources/55803_0.54-PUB.pdf https://www.amd.com/system/files/TechDocs/24594.pdf Depends on following kernel commits: 40bc47b08b6e ("kvm: x86: Enumerate support for CLZERO instruction") 504ce1954fba ("KVM: x86: Expose XSAVEERPTR to the guest") 6d61e3c32248 ("kvm: x86: Expose RDPID in KVM_GET_SUPPORTED_CPUID") 52297436199d ("kvm: svm: Update svm_xsaves_supported") Backports commit 143c30d4d346831a09e59e9af45afdca0331e819 from qem |
