This is the last patch in the series which implements the essentials of the Movable BARs feature, so it is turned by default now. Tested on: - x86_64 with "pci=realloc,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 CC: Oliver O'Halloran <oohall@gmail.com> Signed-off-by: Sergey Miroshnichenko <s.miroshnichenko@yadro.com> --- drivers/pci/pci.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
