(Found on an IOV # capable device using the ipr driver.) # # Recovery fails in pci_enable_resources() at the check on r->parent, # because r->flags is set and r->parent is not. This state is due to # sriov_init() setting the start, end and flags members of the IOV BARs # but the parent not being set later in # pseries_pci_fixup_iov_resources(), because the # "ibm,open-sriov-vf-bar-info" property is missing. # # Correct this by zeroing the resource flags for IOV BARs when they # can't be configured (this is the same method used by sriov_init() and # __pci_read_base()). # # VFs cleared this way can't be enabled later, because that requires # another device tree property, "ibm,number-of-configurable-vfs" as well # as support for the RTAS function "ibm_map_pes". These are all part of # hypervisor support for IOV and it seems unlikely that a hypervisor # would ever partially, but not fully, support it. (None are currently # provided by QEMU/KVM.) # # Signed-off-by: Sam Bobroff <sbobroff@linux.ibm.com> # Reviewed-by: Bryant G.
