[Qemu-devel] [RFC PATCH 00/14] Allow EEH on "normal" sPAPR PCI host bridge

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

I've already posted a patch series that allows VFIO devices on
spapr-pci-host-bridge instead of just on spapr-pci-vfio-host-bridge.
However. it still didn't allow EEH on VFIO devices on the "normal"
host bridge.

This series addresses that, making a number of cleanup along the way.

Because of limitations in both the qemu code and the kernel VFIO+EEH
interface, it only allows EEH if there is just one IOMMU group with
VFIO devices on the host bridge.  This isn't more limited than
spapr-pci-vfio-host-bridge, because it also only supported a single
VFIO group (although it didn't properly enforce that).

David Gibson (14):
  vfio: Start adding VFIO/EEH interface
  spapr_pci: Switch EEH to vfio_eeh_op() interface
  spapr_pci: Expose and generalize spapr_phb_check_vfio_group()
  spapr_pci: Fold spapr_phb_vfio_eeh_configure() into spapr_pci code
  spapr_pci: Fold spapr_phb_vfio_eeh_reset() into spapr_pci code
  spapr_pci: Fold spapr_phb_vfio_eeh_get_state() into spapr_pci code
  spapr_pci: Fold spapr_phb_vfio_eeh_set_option() into spapr_pci code
  spapr_pci: Fold spapr_phb_vfio_eeh_configure() into spapr_pci code
  vfio: Expose a VFIO PCI device's group for EEH
  spapr_pci: Track guest Partitionable Endpoints
  spapr_pci: Allow EEH on spapr-pci-host-bridge
  spapr_pci: (Mostly) remove spapr-pci-vfio-host-bridge
  spapr_pci: Remove finish_realize hook
  vfio: Eliminate vfio_container_ioctl()
