Subject: [PATCH v9 0/9] virtio-iommu: VFIO integration
Date: Mon, 23 Mar 2020 14:16:08 +0530
Message-ID: <20200323084617.1782-1-bbhushan2@marvell.com> (raw)

This patch series integrates VFIO with virtio-iommu.
This is only applicable for PCI pass-through with virtio-iommu.

This series is available at:
https://github.com/bharat-bhushan-devel/qemu.git virtio-iommu-vfio-integration-v8

This is tested with assigning more than one pci devices to Virtual Machine.

v8-v9:
  - Have page size mask per endpint
  - Add PROBE interface, return page size mask
 
v7->v8:
  - Set page size mask as per host
    This fixes issue with 64K host/guest 
  - Device list from IOMMUDevice directly removed VirtioIOMMUNotifierNode
  - Add missing iep->viommu init on post-load

v6->v7:
  - corrected email-address

v5->v6:
  - Rebase to v16 version from Eric
  - Tested with upstream Linux
  - Added a patch from Eric/Myself on removing mmio-region error print in vfio

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
