There is no corresponding support for ARM. The x86 and ia64 support is in arch-specific functions called probe_pci_root_info(). These are actually generic in principle, and I would love it if this functionality could be moved into acpi_pci_root_add() somehow. > I'm guessing the respective root complex driver need to enable and use > this feature. > I'm using PCIe bridge which is operating in ARM, how can I enable or > is there RC driver which uses this feature already? > > [1] http://lwn.net/Articles/373551/ > > thanks! > -- > Jagan. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
