I see this error too on my setup (Xilinx PCIe Root Complex Driver), https://lkml.org/lkml/2014/3/3/183 After digging into it, I see I need to override the API pcibios_get_phb_of_node() to pass my device node. Is this the only possible way? >From the discussion in this thread, I feel am missing something in the dt node. Below is my dt node, please let me know if you see any issues. +++++++++++++++++++++++ pcie{ reg = <XXXX>; ranges = <YYYY>; interrupts = <0 52 4>; pcie_intc: interrupt-controller { interrupt-controller; #address-cells = <0>; #interrupt-cells = <1>; } interrupt-map-mask = <0 0 0 7>; interrupt-map = <0 0 0 1 &pcie_intc 1>, <0 0 0 2 &pcie_intc 2>, <0 0 0 3 &pcie_intc 3>, <0 0 0 4 &pcie_intc 4>; }; Thanks in advance, Srikanth. > > Regards, > Lucas > -- > Pengutronix e.K. | Lucas Stach | > Industrial Linux Solutions | http://www.pengutronix.de/ | > Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-5076 | > Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | > > -- > 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 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
