Here are the features. a. Allow versioned CPUs to specify new cache_info pointers. b. Add EPYC-v4, EPYC-Rome-v3 and EPYC-Milan-v2 fixing the cache_info.complex_indexing. c. Introduce EPYC-Milan-v2 by adding few missing feature bits. d. Add CPU model for AMD EPYC Genoa processor series This series depends on the following recent kernel commits: 8c19b6f257fa ("KVM: x86: Propagate the AMD Automatic IBRS feature to the guest") e7862eda309e ("x86/cpu: Support AMD Automatic IBRS") 5b909d4ae59a ("x86/cpu, kvm: Add the Null Selector Clears Base feature") a9dc9ec5a1fa ("x86/cpu, kvm: Add the NO_NESTED_DATA_BP feature") 0977cfac6e76 ("KVM: nSVM: Implement support for nested VNMI") fa4c027a7956 ("KVM: x86: Add support for SVM's Virtual NMI") --- v4: Minor text changes and function name change in patch1 (Robert Hoo). v3: Refreshed the patches on top of latest master. Add CPU model for AMD EPYC Genoa processor series (zen4) v2: Refreshed the patches on top of latest master. Changed the feature NULL_SELECT_CLEARS_BASE to NULL_SEL_CLR_BASE to match the kernel name. https://lore.kernel.org/kvm/20221205233235.622491-3-kim.phillips@amd.com/ v1: https://lore.kernel.org/kvm/167001034454.62456.7111414518087569436.stgit@bmoger-ubuntu/ v2: https://lore.kernel.org/kvm/20230106185700.28744-1-babu.moger@amd.com/ v3: https://lore.kernel.org/kvm/20230424163401.23018-1-babu.moger@amd.com/ Babu Moger (5): target/i386: Add a couple of feature bits in 8000_0008_EBX target/i386: Add feature bits for CPUID_Fn80000021_EAX target/i386: Add missing feature bits in EPYC-Milan model target/i386: Add VNMI and automatic IBRS feature bits target/i386: Add EPYC-Genoa model to support Zen 4 processor series Michael Roth (2): target/i386: allow versioned CPUs to specify new cache_info target/i386: Add new EPYC CPU versions with updated cache_info target/i386/cpu.c | 375 +++++++++++++++++++++++++++++++++++++++++++++- target/i386/cpu.h | 15 ++ 2 files changed, 384 insertions(+), 6 deletions(-)
