This patch series integrates VFIO with virtio-iommu. This is
tested with assigning 2 pci devices to Virtual Machine.
This version is mainly about rebasing on v9 version on
virtio-iommu device framework from Eric Augur.
This patch series allows PCI pass-through using virtio-iommu.
This series is based on:
- virtio-iommu kernel driver by Jean-Philippe Brucker
[PATCH v5 0/7] Add virtio-iommu driver
git://linux-arm.org/kvmtool-jpb.git virtio-iommu/v0.9
- virtio-iommu device emulation by Eric Augur.
[RFC,v9,00/17] VIRTIO-IOMMU device
https://github.com/eauger/qemu/tree/v3.1.0-rc2-virtio-iommu-v0.9
v4->v5:
- Rebase to v9 version from Eric
- PCIe device hotplug fix
- Added Patch 1/5 from Eric previous series (Eric somehow dropped in
last version.
- Patch "Translate the MSI doorbell in kvm_arch_fixup_msi_route"
already integrated with vsmmu3
v3->v4:
- Rebase to v4 version from Eric
- Fixes from Eric with DPDK in VM
- Logical division in multiple patches
v2->v3:
- This series is based on "[RFC v3 0/8] VIRTIO-IOMMU device"
Which is based on top of v2.10-rc0 that
- Fixed issue with two PCI devices
- Addressed review comments
v1->v2:
- Added trace events
- removed vSMMU3 link in patch description
Bharat Bhushan (4):
virtio-iommu: Add iommu notifier for iommu-map/unmap
virtio-iommu: Call iommu notifier on attach/detach
virtio-iommu: add virtio-iommu replay
virtio-iommu: handle IOMMU Notifier flag changes
Eric Auger (1):
hw/vfio/common: Do not print error when viommu translates into an mmio
region

This only boots in DT mode at the moment with machvirt. Use -virtio-iommu-pci to instantiate the device. About the qemu device, you will find latest changes in the v16 history log: https://patchwork.kernel.org/cover/11382271/ Thanks Eric > > Thanks > -Bharat > > Thanks > > Eric > > > > v4->v5: > > - Rebase to v9 version from Eric > > - PCIe device hotplug fix > > - Added Patch 1/5 from Eric previous series (Eric somehow dropped in > > last version. > > - Patch "Translate the MSI doorbell in kvm_arch_fixup_msi_route" > > already integrated with vsmmu3 > > > > v3->v4: > > - Rebase to v4 version from Eric > > - Fixes from Eric with DPDK in VM > > - Logical division in multiple patches > > > > v2->v3: > > - This series is based on "[RFC v3 0/8] VIRTIO-IOMMU device" > > Which is based on top of v2.10-rc0 that > > - Fixed issue with two PCI devices > > - Addressed review comments > > > > v1->v2: > > - Added trace events > > - removed vSMMU3 link in patch description > > > > Bharat Bhushan (4): > > virtio-iommu: Add iommu notifier for iommu-map/unmap > > virtio-iommu: Call iommu notifier on attach/detach > > virtio-iommu: add virtio-iommu replay > > virtio-iommu: handle IOMMU Notifier flag changes > > > > Eric Auger (1): > > hw/vfio/common: Do not print error when viommu translates into > an mmio > > region > > > > hw/vfio/common.c | 2 - > > hw/virtio/trace-events | 5 + > > hw/virtio/virtio-iommu.c | 190 > ++++++++++++++++++++++++++++++- > > include/hw/virtio/virtio-iommu.h | 6 + > > 4 files changed, 198 insertions(+), 5 deletions(-) > > > > > > -- > -Bharat
