Subject: [RFC v6 24/24] hw/arm/smmuv3: Allow MAP notifiers
Date: Fri, 20 Mar 2020 17:58:40 +0100 [thread overview]
Message-ID: <20200320165840.30057-25-eric.auger@redhat.com> (raw)
In-Reply-To: <20200320165840.30057-1-eric.auger@redhat.com>
We now have all bricks to support nested paging. This
uses MAP notifiers to map the MSIs. So let's allow MAP
notifiers to be registered.
