Subject: [GIT PULL] KVM fixes for Linux 6.11-rc7 From: Paolo Bonzini To: torvalds@linux-foundation.org Cc: linux-kernel@vger.kernel.org, kvm@vger.kernel.org Date: Fri, 6 Sep 2024 11:45:17 -0400 Linus, The following changes since commit 47ac09b91befbb6a235ab620c32af719f8208399: Linux 6.11-rc4 (2024-08-18 13:17:27 -0700) 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 59cbd4eea48fdbc68fc17a29ad71188fea74b28b: KVM: Remove HIGH_RES_TIMERS dependency (2024-09-05 12:04:54 -0400) Many small fixes that accumulated while I was on vacation... ---------------------------------------------------------------- x86: - Fixup missed comments from the REMOVED_SPTE=>FROZEN_SPTE rename. - Ensure a root is successfully loaded when pre-faulting SPTEs. - Grab kvm->srcu when handling KVM_SET_VCPU_EVENTS to guard against accessing memslots if toggling SMM happens to force a VM-Exit. - Emulate MSR_{FS,GS}_BASE on SVM even though interception is always disabled, so that KVM does the right thing if KVM's emulator encounters {RD,WR}MSR. - Explicitly clear BUS_LOCK_DETECT from KVM's caps on AMD, as KVM doesn't yet virtualize BUS_LOCK_DETECT on AMD. - Cleanup the help message for CONFIG_KVM_AMD_SEV, and call out that KVM now supports SEV-SNP too. - Specialize return value of KVM_CHECK_EXTENSION(KVM_CAP_READONLY_MEM), based on VM type - Remove unnecessary dependency on CONFIG_HIGH_RES_TIMERS - Note an RCU quiescent state on guest exit. This avoids a call to rcu_core() if there was a grace period request while guest was running. ---------------------------------------------------------------- Leonardo Bras (1): kvm: Note an RCU quiescent state on guest exit Maxim Levitsky (1): KVM: SVM: fix emulation of msr reads/writes of MSR_FS_BASE and MSR_GS_BASE Paolo Bonzini (1): Merge tag 'kvm-x86-fixes-6.11-rcN' of https://github.com/kvm-x86/linux into kvm-master Ravi Bangoria (1): KVM: SVM: Don't advertise Bus Lock Detect to guest if SVM support is missing Sean Christopherson (2): KVM: x86/mmu: Check that root is valid/loaded when pre-faulting SPTEs KVM: x86: Acquire kvm->srcu when handling KVM_SET_VCPU_EVENTS Steven Rostedt (1): KVM: Remove HIGH_RES_TIMERS dependency Tom Dohrmann (1): KVM: x86: Only advertise KVM_CAP_READONLY_MEM when supported by VM Vitaly Kuznetsov (1): KVM: SEV: Update KVM_AMD_SEV Kconfig entry and mention SEV-SNP Yan Zhao (1): KVM: x86/mmu: Fixup comments missed by the REMOVED_SPTE=>FROZEN_SPTE rename arch/x86/kvm/Kconfig | 7 ++++--- arch/x86/kvm/mmu/mmu.c | 4 +++- arch/x86/kvm/mmu/spte.c | 6 +++--- arch/x86/kvm/mmu/spte.h | 2 +- arch/x86/kvm/mmu/tdp_mmu.c | 8 ++++---- arch/x86/kvm/svm/svm.c | 15 +++++++++++++++ arch/x86/kvm/x86.c | 5 ++++- include/linux/context_tracking.h | 6 ++++-- include/linux/kvm_host.h | 10 +++++++++- 9 files changed, 47 insertions(+), 16 deletions(-) .
