[PATCH v3 1/4] KVM: arm64: Avoid vcpu->mutex v. kvm->lock inversion in CPU_ON

by Oliver Upton

KVM/arm64 had the lock ordering backwards on vcpu->mutex and kvm->lock from the very beginning. One such example is the way vCPU resets are handled: the kvm->lock is acquired while handling a guest CPU_ON PSCI call. Add a dedicated lock to serialize writes to kvm_vcpu_arch::{mp_state, reset_state}. Promote all accessors of mp_state to {READ,WRITE}_ONCE() as readers do not acquire the mp_state_lock. While at it, plug yet another race by taking the mp_state_lock in the KVM_SET_MP_STATE ioctl handler. As changes to MP state are now guarded with a dedicated lock, drop the kvm->lock acquisition from the PSCI CPU_ON path. Similarly, move the reader of reset_state outside of the kvm->lock and instead protect it with the mp_state_lock. Note that writes to reset_state::reset have been demoted to regular stores as both readers and writers acquire the mp_state_lock. While the kvm->lock inversion still exists in kvm_reset_vcpu(), at least now PSCI CPU_ON no longer depends on it for serializing vCPU reset.

[PATCH v2] KVM: SVM: Flush Hyper-V TLB when required

by Jeremi Piotrowski

From: Jeremi Piotrowski <jpiotrowski(a)linux.microsoft.com> The Hyper-V "EnlightenedNptTlb" enlightenment is always enabled when KVM is running on top of Hyper-V and Hyper-V exposes support for it (which is always). On AMD CPUs this enlightenment results in ASID invalidations not flushing TLB entries derived from the NPT. To force the underlying (L0) hypervisor to rebuild its shadow page tables, an explicit hypercall is needed. The original KVM implementation of Hyper-V's "EnlightenedNptTlb" on SVM only added remote TLB flush hooks. This worked out fine for a while, as sufficient remote TLB flushes where being issued in KVM to mask the problem. Since v5.17, changes in the TDP code reduced the number of flushes and the out-of-sync TLB prevents guests from booting successfully. Split svm_flush_tlb_current() into separate callbacks for the 3 cases (guest/all/current), and issue the required Hyper-V hypercall when a Hyper-V TLB flush is needed. The most important case where the TLB flush was missing is when loading a new PGD, which is followed by what is now svm_flush_tlb_current(). Cc: stable(a)vger.kernel.org # v5.17+ Fixes: 1e0c7d40758b ("KVM: SVM: hyper-v: Remote TLB flush for SVM") Link: https://lore.kernel.org/lkml/43980946-7bbf-dcef-7e40-af904c456250@linux.mic… Suggested-by: Sean Christopherson <seanjc(a)google.com> Signed-off-by: Jeremi Piotrowski <jpiotrowski(a)linux.microsoft.com> --- Changes since v1: - lookup enlightened_npt_tlb in vmcb to determine whether to do the flush - when KVM wants a hyperv_flush_guest_mapping() call, don't try to optimize it out - don't hide hyperv flush behind helper, make it visible in svm.c arch/x86/kvm/kvm_onhyperv.h | 5 +++++ arch/x86/kvm/svm/svm.c | 37 ++++++++++++++++++++++++++++++--- arch/x86/kvm/svm/svm_onhyperv.h | 15 +++++++++++++ 3 files changed, 54 insertions(+), 3 deletions(-) diff --git a/arch/x86/kvm/kvm_onhyperv.h b/arch/x86/kvm/kvm_onhyperv.h index 287e98ef9df3..67b53057e41c 100644 --- a/arch/x86/kvm/kvm_onhyperv.h +++ b/arch/x86/kvm/kvm_onhyperv.h @@ -12,6 +12,11 @@ int hv_remote_flush_tlb_with_range(struct kvm *kvm, int hv_remote_flush_tlb(struct kvm *kvm); void hv_track_root_tdp(struct kvm_vcpu *vcpu, hpa_t root_tdp); #else /* !CONFIG_HYPERV */ +static inline int hv_remote_flush_tlb(struct kvm *kvm) +{ + return -1; +} + static inline void hv_track_root_tdp(struct kvm_vcpu *vcpu, hpa_t root_tdp) { } diff --git a/arch/x86/kvm/svm/svm.c b/arch/x86/kvm/svm/svm.c index 252e7f37e4e2..f25bc3cbb250 100644 --- a/arch/x86/kvm/svm/svm.c +++ b/arch/x86/kvm/svm/svm.c @@ -3729,7 +3729,7 @@ static void svm_enable_nmi_window(struct kvm_vcpu *vcpu) svm->vmcb->save.rflags |= (X86_EFLAGS_TF | X86_EFLAGS_RF); } -static void svm_flush_tlb_current(struct kvm_vcpu *vcpu) +static void svm_flush_tlb_asid(struct kvm_vcpu *vcpu) { struct vcpu_svm *svm = to_svm(vcpu); @@ -3753,6 +3753,37 @@ static void svm_flush_tlb_current(struct kvm_vcpu *vcpu) svm->current_vmcb->asid_generation--; } +static void svm_flush_tlb_current(struct kvm_vcpu *vcpu) +{ + hpa_t root_tdp = vcpu->arch.mmu->root.hpa; + + /* + * When running on Hyper-V with EnlightenedNptTlb enabled, explicitly + * flush the NPT mappings via hypercall as flushing the ASID only + * affects virtual to physical mappings, it does not invalidate guest + * physical to host physical mappings. + */ + if (svm_hv_is_enlightened_tlb_enabled(vcpu) && VALID_PAGE(root_tdp)) + hyperv_flush_guest_mapping(root_tdp); + + svm_flush_tlb_asid(vcpu); +} + +static void svm_flush_tlb_all(struct kvm_vcpu *vcpu) +{ + /* + * When running on Hyper-V with EnlightenedNptTlb enabled, remote TLB + * flushes should be routed to hv_remote_flush_tlb() without requesting + * a "regular" remote flush.

[PATCH] ASoC: hdac_hdmi: use set_stream() instead of set_tdm_slots()

hdac_hdmi was not updated to use set_stream() instead of set_tdm_slots() in the original commit so HDMI no longer produces audio.
