Yes, but that only works when called on a Scsi_Device attached to the controller. So each controller needs at least one scsi device (disk, cdrom, whatever) attached, such that there's a /dev/sd* file to open and call this ioctl. That'll get you the pci bus:dev.fn tuple. Then on x86 systems at least, the PCI IRQ Routing Table ($PIR table in BIOS) can tell you if your device is embedded or add-in, and which slot number BIOS calls it. A copy of David A. Hinds' dump_pirq script can be found here: http://linux.dell.com/files/tools/dump_pirq Device 00:04.0 (slot 0): Ethernet controller Device 00:06.0 (slot 0): Device 00:08.0 (slot 1): Class ff00 Device 00:0f.0 (slot 0): Host bridge Device 01:08.0 (slot 0): PCI bridge Device 01:06.0 (slot 0): Ethernet controller Device 02:06.0 (slot 0): SCSI storage controller Device 03:06.0 (slot 2): Device 03:08.0 (slot 3): Device 08:06.0 (slot 4): Device 08:08.0 (slot 5): Device 0d:06.0 (slot 6): RAID bus controller Device 0d:08.0 (slot 7): Slot 0 lines are embedded, the other values should pretty closely correspond to the silkscreen text on the motherboards. That's about as close as you get.
