Hi, >So its odd that scanning of the second bus didn't report any devices. Do you have code that implements ppc_md.pci_exclude_device ?
not that I'm aware of >You might also want to put some code in the indirect PCI ops (indirect.c) to see what actual values you are getting from various indirect_read_config() calls. To make sure that ppc_md.pci_exclude_device is not implemented, I've put some printouts inside indirect_read_config(): I print various parameters when the function is called, and when it returns and note that: 1. indirect_read_config() is called 422 times: 174 times for [/pcie@ffe0a000] (controller where the device is not detected) 248 times for [/pcie@ffe09000] 2. ppc_md.pci_exclude_device is always NULL 3. the function always returns with PCIBIOS_SUCCESSFUL 4. the only call to indirect_read_config() inside which bus_no=0x3, returns with the following log: pci_bus 0001:03: scanning bus -> ind_r_config - [/pcie@ffe0a000] devfn=0x0 len=0x4 hose->indirect_type=0x16 hose->first_busno=0x2 bus- >number=0x3 -> ind_r_config [/pcie@ffe0a000] - (bus_no=0x3 reg=0x0 cfg_data=0xffffffff len=0xff7eb004) val=0x4 PCIBIOS_SUCCESSFUL the entire log is about 116Kb and is available in [1] or [2] (didn't feel like pasting so much data on the ML) thanx alot, Davide [1] http://pastebin.com/JaPGmmfs [2] http://paste2.org/p/2273728 Invita i tuoi amici e Tiscali ti premia!
