I'm a moron and initially based this on kvm/next, and didn't notice until the diffstat for the pull request was absurdly large. As a result, all commits were *just* rebased, like 5 minutes ago. I smoke tested the branch, but didn't do anywhere near my usual level of testing. I'm sending it now, because I suspect it'll be far easier on you to get this today, and because we've probably got bigger problems if these don't work on kvm/master. *sigh* The following changes since commit 7d4050728c83aa63828494ad0f4d0eb4faf5f97a: Merge tag 'vfs-6.13-rc1.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs (2024-11-27 08:11:46 -0800) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-fixes-6.13-rcN for you to fetch changes up to 386d69f9f29b0814881fa4f92ac7b8dfa9b4f44a: KVM: x86/mmu: Treat TDP MMU faults as spurious if access is already allowed (2024-12-19 17:47:52 -0800) ---------------------------------------------------------------- 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. ---------------------------------------------------------------- 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 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/x86.c | 2 +- 7 files changed, 30 insertions(+), 22 deletions(-)
