From e253aaf0af51c1e4dc7dd3b26ea8e666bf9a2d8d Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Tue, 7 May 2013 14:35:44 -0600 Subject: PCI: Delay final fixups until resources are assigned Commit 4f535093cf "PCI: Put pci_dev in device tree as early as possible" moved final fixups from pci_bus_add_device() to pci_device_add(). But pci_device_add() happens before resource assignment, so BARs may not be valid yet. Typical flow for hot-add: pciehp_configure_device pci_scan_slot pci_scan_single_device pci_device_add pci_fixup_device(pci_fixup_final, dev) # previous location # resource assignment happens here pci_bus_add_devices pci_bus_add_device pci_fixup_device(pci_fixup_final, dev) # new location [bhelgaas: changelog, move fixups to pci_bus_add_device()] Reference: https://lkml.kernel.org/r/20130415182614.GB9224@xanatos Reported-by: David Bulkow Tested-by: David Bulkow Signed-off-by: Yinghai Lu Signed-off-by: Bjorn Helgaas CC: stable@vger.kernel.org # v3.9+ --- drivers/pci/bus.c | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/pci/bus.c') diff --git a/drivers/pci/bus.c b/drivers/pci/bus.c index 748f8f3e9ff5..32e66a6f12d9 100644 --- a/drivers/pci/bus.c +++ b/drivers/pci/bus.c @@ -174,6 +174,7 @@ int pci_bus_add_device(struct pci_dev *dev) * Can not put in pci_device_add yet because resources * are not assigned yet for some devices. */ + pci_fixup_device(pci_fixup_final, dev); pci_create_sysfs_dev_files(dev); dev->match_driver = true; -- cgit v1.2.3
