Linus, The following changes since commit 916b7f42b3b3b539a71c204a9b49fdc4ca92cd82: kvm: retry nx_huge_page_recovery_thread creation (2025-03-01 02:54:18 -0500) 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 ea9bd29a9c0d757b3384ae3e633e6bbaddf00725: Merge tag 'kvm-x86-fixes-6.14-rcN.2' of https://github.com/kvm-x86/linux into HEAD (2025-03-09 03:44:06 -0400) This remains quite an active rc period, but these are "just" bugs and issues introduced during this merge window. So, no big deal overall. Paolo ---------------------------------------------------------------- KVM/arm64 fixes for 6.14, take #4 * Fix a couple of bugs affecting pKVM's PSCI relay implementation when running in the hVHE mode, resulting in the host being entered with the MMU in an unknown state, and EL2 being in the wrong mode. x86: * Set RFLAGS.IF in C code on SVM to get VMRUN out of the STI shadow. * Ensure DEBUGCTL is context switched on AMD to avoid running the guest with the host's value, which can lead to unexpected bus lock #DBs. * Suppress DEBUGCTL.BTF on AMD (to match Intel), as KVM doesn't properly emulate BTF. KVM's lack of context switching has meant BTF has always been broken to some extent. * Always save DR masks for SNP vCPUs if DebugSwap is *supported*, as the guest can enable DebugSwap without KVM's knowledge. * Fix a bug in mmu_stress_tests where a vCPU could finish the "writes to RO memory" phase without actually generating a write-protection fault. * Fix a printf() goof in the SEV smoke test that causes build failures with -Werror. * Explicitly zero EAX and EBX in CPUID.0x8000_0022 output when PERFMON_V2 isn't supported by KVM. ---------------------------------------------------------------- Ahmed Genidi (1): KVM: arm64: Initialize SCTLR_EL1 in __kvm_hyp_init_cpu() Mark Rutland (1): KVM: arm64: Initialize HCR_EL2.E2H early Paolo Bonzini (2): Merge tag 'kvmarm-fixes-6.14-4' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD Merge tag 'kvm-x86-fixes-6.14-rcN.2' of https://github.com/kvm-x86/linux into HEAD Sean Christopherson (11): KVM: SVM: Set RFLAGS.IF=1 in C code, to get VMRUN out of the STI shadow KVM: selftests: Assert that STI blocking isn't set after event injection KVM: SVM: Drop DEBUGCTL[5:2] from guest's effective value KVM: SVM: Suppress DEBUGCTL.BTF on AMD KVM: x86: Snapshot the host's DEBUGCTL in common x86 KVM: SVM: Manually context switch DEBUGCTL if LBR virtualization is disabled KVM: x86: Snapshot the host's DEBUGCTL after disabling IRQs KVM: SVM: Save host DR masks on CPUs with DebugSwap KVM: SVM: Don't rely on DebugSwap to restore host DR0..DR3 KVM: selftests: Ensure all vCPUs hit -EFAULT during initial RO stage KVM: selftests: Fix printf() format goof in SEV smoke test Xiaoyao Li (1): KVM: x86: Explicitly zero EAX and EBX when PERFMON_V2 isn't supported by KVM arch/arm64/include/asm/el2_setup.h | 31 +++++++++++--- arch/arm64/kernel/head.S | 22 ++-------- arch/arm64/kvm/hyp/nvhe/hyp-init.S | 10 +++-- arch/arm64/kvm/hyp/nvhe/psci-relay.c | 3 ++ arch/x86/include/asm/kvm_host.h | 1 + arch/x86/kvm/cpuid.c | 2 +- arch/x86/kvm/svm/sev.c | 24 +++++++---- arch/x86/kvm/svm/svm.c | 49 ++++++++++++++++++++++ arch/x86/kvm/svm/svm.h | 2 +- arch/x86/kvm/svm/vmenter.S | 10 +---- arch/x86/kvm/vmx/vmx.c | 8 +--- arch/x86/kvm/vmx/vmx.h | 2 - arch/x86/kvm/x86.c | 2 + tools/testing/selftests/kvm/mmu_stress_test.c | 21 ++++++---- .../selftests/kvm/x86/nested_exceptions_test.c | 2 + tools/testing/selftests/kvm/x86/sev_smoke_test.c | 3 +- 16 files changed, 130 insertions(+), 62 deletions(-)
