The patch adds the following functionality:
1. Implements VFIO-IOMMU host kernel driver support;
2. Implements interface between SPAPR TCE and VFIO via
sPAPRVFIOData's map/unmap hooks;
3. Implements PHB scan for devices within the same IOMMU group.
To use VFIO on spapr platform, the "spapr-pci-host-bridge" device needs
to be created with mandatory "index" and "iommu" properties such as:
-device spapr-pci-host-bridge,busname=USB,iommu=4,index=5
where:
"index" - PHB number which is used to build all other PHB properties
such as MMIO window, BUID, etc;
"iommu" - IOMMU ID which represents a Partitionable Endpoint.
Optional parameters are:
"forceaddr" - forces QEMU to assign device:function from the host address;
"multifunction" - enables multifunction what might make sense if the user
wants to use the configuration from the host in the guest such as
NEC USB PCI adapter which is visible as a single device with 3 PCI
functions, without this switch QEMU will create 3 device with 1 function
on each;
"scan" - disables scan and lets the user put to QEMU only some devices
from PE;
"busname" - name of the bus, it used to connect vfio-pci devices with
a PHB when scan is disabled.
If scan is disabled, no PCI device is automatically added and the user
has to add them manuall as in the example below which adds PHB and
3 PCI devices::
-device spapr-pci-host-bridge,busname=USB,iommu=4,scan=0,index=5 \
-device vfio-pci,host=4:0:1.0,addr=1.0,bus=USB,multifunction=true \
-device vfio-pci,host=4:0:1.1,addr=1.1 \
-device vfio-pci,host=4:0:1.2,addr=1.2
