Subject: [PATCH v8 20/29] iommu/smmuv3: Implement bind/unbind_guest_msi
Date: Sun, 26 May 2019 18:09:55 +0200 [thread overview]
Message-ID: <20190526161004.25232-21-eric.auger@redhat.com> (raw)
In-Reply-To: <20190526161004.25232-1-eric.auger@redhat.com>
The bind/unbind_guest_msi() callbacks check the domain
is NESTED and redirect to the dma-iommu implementation.
Signed-off-by: Eric Auger <eric.auger@redhat.com>
