Tested on: - x86_64 with "pci=realloc,assign-busses,use_crs,pcie_bus_peer2peer" command line argument; - POWER8 PowerNV+PHB3 ppc64le with "pci=realloc,pcie_bus_peer2peer". In case of problems it is still can be overridden by the following command line option: pcie_movable_bars=off Signed-off-by: Sergey Miroshnichenko --- drivers/pci/pci-driver.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/drivers/pci/pci-driver.c b/drivers/pci/pci-driver.c index d11909e79263..a8124e47bf6e 100644 --- a/drivers/pci/pci-driver.c +++ b/drivers/pci/pci-driver.c @@ -1688,8 +1688,6 @@ static int __init pci_driver_init(void) { int ret; - pci_add_flags(PCI_IMMOVABLE_BARS); - ret = bus_register(&pci_bus_type); if (ret) return ret;
