RH-Commit: [47/67] c1a40cdab9bf62b16cb428d57a20b3e0eaa6de38 (eauger1/centos-qemu-kvm)
|
||
|
|
|
||

|
When the legacy and iommufd backends were introduced, a set of common
|
||
|
|
vfio-pci routines were exported in pci.c for both backends to use :
|
||
|
|
|
||
|
|
vfio_pci_pre_reset
|
||
|
|
vfio_pci_get_pci_hot_reset_info
|
||
|
|
vfio_pci_host_match
|
||
|
|
vfio_pci_post_reset
|
||
|
|
|
||
|
|
This introduced a build failure on PPC when --without-default-devices
|
||
|
|
is use because VFIO is always selected in ppc/Kconfig but VFIO_PCI is
|
||
|
|
not.
|
||
|
|
|
||
|
|
Use an 'imply VFIO_PCI' in ppc/Kconfig and bypass compilation of the
|
||
|
|
VFIO EEH hooks routines defined in hw/ppc/spapr_pci_vfio.c with
|
||
|
|
CONFIG_VFIO_PCI.
