This is v4 of the series posted here: http://lkml.kernel.org/r/cover.1740036492.git.naveen@xxxxxxxxxx This series has been significantly re-worked based on the feedback received on v3, as well as to accommodate upstream changes to SVM and AVIC code. I have not picked up Vasant's and Pankaj's review tags for that purpose. Kindly review again. - Naveen Naveen N Rao (AMD) (7): KVM: SVM: Limit AVIC physical max index based on configured max_vcpu_ids KVM: SVM: Add a helper to look up the max physical ID for AVIC KVM: SVM: Replace hard-coded value 0x1FF with the corresponding macro KVM: SVM: Expand AVIC_PHYSICAL_MAX_INDEX_MASK to be a 12-bit field KVM: SVM: Move AVIC Physical ID table allocation to vcpu_precreate() x86/cpufeatures: Add X86_FEATURE_X2AVIC_EXT KVM: SVM: Add AVIC support for 4k vCPUs in x2AVIC mode arch/x86/include/asm/cpufeatures.h | 1 + arch/x86/include/asm/svm.h | 5 +- arch/x86/kvm/svm/svm.h | 1 + arch/x86/kernel/cpu/scattered.c | 1 + arch/x86/kvm/svm/avic.c | 76 ++++++++++++++++++++++++------ arch/x86/kvm/svm/svm.c | 9 ++++ 6 files changed, 78 insertions(+), 15 deletions(-) base-commit: 91b392ada892a2e8b1c621b9493c50f6fb49880f -- 2.50.1
