[PATCH v6 5/8] KVM: selftests: Enable KVM_CAP_DIRTY_LOG_RING_WITH_BITMAP if possible

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Enable KVM_CAP_DIRTY_LOG_RING_WITH_BITMAP if it's supported. Otherwise,
we will fail to enable KVM_CAP_DIRTY_LOG_RING_ACQ_REL on aarch64.
