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
