I am working on developing PCI based Linux Device Driver. Could you please =
send me few sample code. I am looking for the code which has more informati=

First, please fix your mail client - it's munging your mails rather
badly, as you can see.

The entire linux kernel is open source - just look under drivers/ for
plenty of example code. If you're stuck, a 'grep linux/pci.h -R
drivers' should find you PCI drivers. (Note that drivers/pci contains
pci core code, which is probably not what you want)

Please start by reading Documentation/PCI/pci.txt and MSI-HOWTO.txt
Lots more useful info in Documentation/ that should help you out
(e.g. suspend/resume, hotplug, DMA API, etc)
Here are some specific driver examples:
drivers/net/forcedeth.c
drivers/net/e1000e/
drivers/scsi/mpt2sas/
drivers/ata/sata_sil24.c
drivers/ata/sata_mv.c
hth,

Chapter 12 from the Linux Device Driver book might be useful, too.
