I have a board which sits on PCIe slot of a x86 machine running 2.6 kernel. My
goal is to get a consistent way of identifying the physical slot ID from the
pci_dev structure associated with a device on the board (multiple devices).
When I do an lspci -t , the device shows up this:
0x1c ----- 0xa ------- 0x9
|
|--device 1
|--device 2 and so on
When I walk thru the bus with a while loop
bus = pDev->bus;
do
{
printk (.... "bus number : %x", bus->number )
} while (bus = bus->parent)
I get 0x9 , 0xa , 0x0
I have tried almost all of the feilds of bus , even tried traversing thru
bus_list, but I cant get that 0x1c programmetically. 0x1c is probably the bus
number for PCI-PCIe bridge, most fields of bus structure become 0 for this.. Is
there a easy way to get this via pci_dev structure?
Thanks
