[PATCH v2 2/2] PCI: Don't disable PF's memory decoding when enabling SRIOV

2016-09-29 Thread Gavin Shan
pci_update_resource() might be called to update (shift) IOV BARs in PPC PowerNV specific pcibios_sriov_enable() when enabling PF's SRIOV capability. At that point, the PF have been functional if the SRIOV is enabled through sysfs entry "sriov_numvfs". The PF's memory decoding (0x2 in PCI_COMMAND) s
