[Qemu-devel] [PATCH 0/4] Allow VFIO devices on spapr-pci-host-bridge

[David Gibson <david@gibson.dropbear.id.au>]

At present, VFIO PCI devices attached to an spapr-pci-host-bridge
device (the regular PCI host bridge for the pseries machine type)
won't quite work properly.

I've recently posted some extensions to VFIO that are almost enough to
allow these to work - this series contains the final necessary changes
to the host bridge implementation itself to let that work.

NOTE: This must be applied on top of my recent series of patches to
      the VFIO core code.  I'm sending this out now, in the hopes that
      it can be reviewed and ready to apply as soon as the VFIO
      changes are merged.

David Gibson (4):
  spapr_pci: Allow PCI host bridge DMA window to be configured
  spapr_iommu: Rename vfio_accel parameter
  spapr_iommu: Provide a function to switch a TCE table to allowing VFIO
  spapr_pci: Allow VFIO devices to work on the normal PCI host bridge
