As per the p2020rm, PCIe legacy INTA is shared with IRQ0 for this ctlr, which is the exactly the case with other SoC's p2020ds, mpc8536ds, mpc8572ds. To me it seems like a board issue and it needs to be followed up. I plugged in ralink rt2860 pcie wirless card in the mini-pcie slot of p2020rdb, which ran fine becaused it used MSI by default. How hard is it to enable MSI in the atheros wireless driver. > > Thanks. > > Felix. > Thanks, Vivek _______________________________________________ Linuxppc-dev mailing list [email protected] https://lists.ozlabs.org/listinfo/linuxppc-dev
