Thank you!
Linus, The following changes since commit 78d4f34e2115b517bcbfe7ec0d018bbbb6f9b0b8: Linux 6.13-rc3 (2024-12-15 15:58:23 -0800) are available in the Git repository at: https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus for you to fetch changes up to 8afa5b10af9d748b055a43949f819d9991d63938: Merge tag 'kvm-x86-fixes-6.13-rcN' of https://github.com/kvm-x86/linux into HEAD (2024-12-22 12:07:16 -0500) ---------------------------------------------------------------- KVM x86 fixes for 6.13: - Disable AVIC on SNP-enabled systems that don't allow writes to the virtual APIC page, as such hosts will hit unexpected RMP #PFs in the host when running VMs of any flavor. - Fix a WARN in the hypercall completion path due to KVM trying to determine if a guest with protected register state is in 64-bit mode (KVM's ABI is to assume such guests only make hypercalls in 64-bit mode). - Allow the guest to write to supported bits in MSR_AMD64_DE_CFG to fix a regression with Windows guests, and because KVM's read-only behavior appears to be entirely made up. - Treat TDP MMU faults as spurious if the faulting access is allowed given the existing SPTE. This fixes a benign WARN (other than the WARN itself) due to unexpectedly replacing a writable SPTE with a read-only SPTE. - Emit a warning when KVM is configured with ignore_msrs=1 and also to hide the MSRs that the guest is looking for from the kernel logs. ignore_msrs can trick guests into assuming that certain processor features are present, and this in turn leads to bogus bug reports. ---------------------------------------------------------------- Paolo Bonzini (2): KVM: x86: let it be known that ignore_msrs is a bad idea Merge tag 'kvm-x86-fixes-6.13-rcN' of https://github.com/kvm-x86/linux into HEAD Sean Christopherson (3): KVM: x86: Play nice with protected guests in complete_hypercall_exit() KVM: SVM: Allow guest writes to set MSR_AMD64_DE_CFG bits KVM: x86/mmu: Treat TDP MMU faults as spurious if access is already allowed Suravee Suthikulpanit (1): KVM: SVM: Disable AVIC on SNP-enabled system without HvInUseWrAllowed feature Wolfram Sang (1): KVM: VMX: don't include '<linux/find.h>' directly arch/x86/include/asm/cpufeatures.h | 1 + arch/x86/kvm/mmu/mmu.c | 12 ------------ arch/x86/kvm/mmu/spte.h | 17 +++++++++++++++++ arch/x86/kvm/mmu/tdp_mmu.c | 5 +++++ arch/x86/kvm/svm/avic.c | 6 ++++++ arch/x86/kvm/svm/svm.c | 9 --------- arch/x86/kvm/vmx/posted_intr.h | 2 +- arch/x86/kvm/x86.c | 9 ++++++++- 8 files changed, 38 insertions(+), 23 deletions(-)
