As the result, pnv_ioda_setup_bus_iommu_group() # does not create groups any more, it only adds devices to groups. # # This works fine for boot time devices. However IOMMU groups for # SRIOV's VFs were added by pnv_ioda_setup_bus_iommu_group() so this got # broken: pnv_tce_iommu_bus_notifier() expects a group to be registered # for VF and it is not. # # This adds missing group registration and adds a NULL pointer check # into the bus notifier so we won't crash if there is no group, although # it is not expected to happen now because of the change above. # # Example oops seen prior to this patch: # # $ echo 1 > /sys/bus/pci/devices/0000\:01\:00.0/sriov_numvfs # Unable to handle kernel paging request for data at address 0x00000030 # Faulting
