From: Paolo Bonzini
Date: Wed May 06 2020 - 07:10:43 EST


I am posting all the pending patches as a full series because I found
another issue on AMD, which is easily fixed with the last patch but has
dependencies on the patches to keep DR6 synchronized with vcpu->arch.dr6.

Paolo Bonzini (5):
KVM: x86: fix DR6 delivery for various cases of #DB injection
KVM: SVM: keep DR6 synchronized with vcpu->arch.dr6
KVM: x86: simplify dr6 accessors in kvm_x86_ops
KVM: x86, SVM: do not clobber guest DR6 on KVM_EXIT_DEBUG
KVM: VMX: pass correct DR6 for GD userspace exit

Peter Xu (4):
KVM: X86: Declare KVM_CAP_SET_GUEST_DEBUG properly
KVM: X86: Set RTM for DB_VECTOR too for KVM_EXIT_DEBUG
KVM: X86: Fix single-step with KVM_SET_GUEST_DEBUG
KVM: selftests: Add KVM_SET_GUEST_DEBUG test
