Re: PCI Driver

["Vinay" <vinay.rao@ionidea.com>]

In user program you can't use "pci_find_device" . PCI methods can be called
from the kernel only .
PCI devices have a PCI configuration space . PCI configuration space stores
all the details of the
device for accessing the device u must map the registers to the memory so
that u can read or write
into the registers . For more hardware details (registers ) u must have the
device datasheet from the vendor .

Vinay
