Hi christoffer/marc, Could you review this simple patch to enable the 32 bit KVM vcpu event supports? Because below user space patch depended on it. thanks https://patchwork.kernel.org/patch/10617601/ > subject: [PATCH 2/2] arm/arm64: KVM: share the check for vcpu events capability > > The commit 539aee0edb9f ("KVM: arm64: Share the parts of get/set events useful to 32bit") shares the get/set events helper for arm64 > and arm32, it is better also share the check for vcpu events capability. > > User space will check whether KVM supports vcpu events through KVM_CAP_VCPU_EVENTS IOCTL. > > Signed-off-by: Dongjiu Geng <gengdongjiu@xxxxxxxxxx> > --- > For the 32 bit guest migration, it needs to enable the vcpu events > > --- > arch/arm64/kvm/reset.c | 1 - > virt/kvm/arm/arm.c | 1 + > 2 files changed, 1 insertion(+), 1 deletion(-) > > diff --git a/arch/arm64/kvm/reset.c b/arch/arm64/kvm/reset.c index fd37c53..e50245e 100644 > --- a/arch/arm64/kvm/reset.c > +++ b/arch/arm64/kvm/reset.c > @@ -82,7 +82,6 @@ int kvm_arch_vm_ioctl_check_extension(struct kvm *kvm, long ext) > break; > case KVM_CAP_SET_GUEST_DEBUG: > case KVM_CAP_VCPU_ATTRIBUTES: > - case KVM_CAP_VCPU_EVENTS: > r = 1; > break; > default: > diff --git a/virt/kvm/arm/arm.c b/virt/kvm/arm/arm.c index 40e79ea..64e5d97 100644 > --- a/virt/kvm/arm/arm.c > +++ b/virt/kvm/arm/arm.c > @@ -212,6 +212,7 @@ int kvm_vm_ioctl_check_extension(struct kvm *kvm, long ext) > case KVM_CAP_READONLY_MEM: > case KVM_CAP_MP_STATE: > case KVM_CAP_IMMEDIATE_EXIT: > + case KVM_CAP_VCPU_EVENTS: > r = 1; > break; > case KVM_CAP_ARM_SET_DEVICE_ADDR: > -- > 1.9.1 > _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
