No major objections to any of the changes. Can you also take a look at my other patch to kvm-unit-tests: "pmu_lbr: drop check for MSR_LBR_TOS != 0" Thanks, Best regards, Maxim Levitsky
v2 of Maxim's series to add testcases for canonical checks of various MSRs, segment bases, and instructions that were found to ignore CR4.LA57 on CPUs that support 5 level paging. v2: - Fold into existing la57 test. - Always skip SYSENTER tests (they fail when run in a VM). - Lots of cosmetics cleanups (see v1 feedback for details). v1: https://lore.kernel.org/all/20240907005440.500075-1-mlevitsk@redhat.com Maxim Levitsky (5): x86: Add _safe() and _fep_safe() variants to segment base load instructions x86: Add a few functions for gdt manipulation x86: Move struct invpcid_desc descriptor to processor.h x86: Add testcases for writing (non)canonical LA57 values to MSRs and bases nVMX: add a test for canonical checks of various host state vmcs12 fields.
