[PATCH OLK-6.6 0/1] KVM: arm64: Reject HDBSS enable when dirty ring is active

Enabling HDBSS alongside the dirty ring leads to a guest hang after live migration. This occurs because HDBSS currently lacks support for the dirty ring data structures, preventing proper dirty page tracking and synchronization during migration. Add a check in kvm_cap_arm_enable_hdbss() to return -EINVAL if the dirty ring is already in use to prevent this conflicting and unsafe configuration. patchapply (1): KVM: arm64: Reject HDBSS enable when dirty ring is active arch/arm64/kvm/arm.c | 5 +++++ 1 file changed, 5 insertions(+) -- 2.33.0
