Subject: [PATCH for-5.0 v11 10/20] virtio-iommu-pci: Add virtio iommu pci support
Date: Fri, 22 Nov 2019 19:29:33 +0100 [thread overview]
Message-ID: <20191122182943.4656-11-eric.auger@redhat.com> (raw)
In-Reply-To: <20191122182943.4656-1-eric.auger@redhat.com>
This patch adds virtio-iommu-pci, which is the pci proxy for
the virtio-iommu device.
Signed-off-by: Eric Auger <eric.auger@redhat.com>
---
v10 -> v11:
- add the reserved_regions array property
v9 -> v10:
- include "hw/qdev-properties.h" header
v8 -> v9:
- add the msi-bypass property
- create virtio-iommu-pci.c
