Hi,
At first I would like to say thanks to Saumendra Das and Greg KH for your response and I believe 8250/16550 family of Serial Driver is really good to start as it easily available in market.
I am completely new to this PCI device driver so I just wanted to know that how kernel build pci_dev structure during pci initialization time. what are the pci function are being called and if I take 8250 server family then how interaction is happens between kernel and pci device.
To know more about this i went to below files
drivers\tty\serial\8250\8250_pci.c
drivers\pci (some files)
Please suggest me if i am going anything wrong.
Regards
Rabi

Please go through some simple PCI driver code to know more about PCI programming.
8250/16550 family of Serial Driver is a good one to start with.
Thanks,
