A small series for Dongli to cleanup the passthrough MSR bitmap code, and a handful of one-off changes. The following changes since commit 41bccc98fb7931d63d03f326a746ac4d429c1dd3: Linux 6.8-rc2 (2024-01-28 17:01:12 -0800) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-vmx-6.9 for you to fetch changes up to 259720c37d51aae21f70060ef96e1f1b08df0652: KVM: VMX: Combine "check" and "get" APIs for passthrough MSR lookups (2024-02-27 12:29:46 -0800) ---------------------------------------------------------------- KVM VMX changes for 6.9: - Fix a bug where KVM would report stale/bogus exit qualification information when exiting to userspace due to an unexpected VM-Exit while the CPU was vectoring an exception. - Add a VMX flag in /proc/cpuinfo to report 5-level EPT support. - Clean up the logic for massaging the passthrough MSR bitmaps when userspace changes its MSR filter. ---------------------------------------------------------------- Chao Gao (1): KVM: VMX: Report up-to-date exit qualification to userspace Dongli Zhang (2): KVM: VMX: fix comment to add LBR to passthrough MSRs KVM: VMX: return early if msr_bitmap is not supported Sean Christopherson (2): x86/cpu: Add a VMX flag to enumerate 5-level EPT support to userspace KVM: VMX: Combine "check" and "get" APIs for passthrough MSR lookups arch/x86/include/asm/vmxfeatures.h | 1 + arch/x86/kernel/cpu/feat_ctl.c | 2 ++ arch/x86/kvm/vmx/vmx.c | 72 ++++++++++++++++---------------------- 3 files changed, 34 insertions(+), 41 deletions(-)
