Hi all
This is sreeram

First, please do not use SMS, AOL or abbreviate text when posting. One it is not professional and you really cannot convey your query properly. Please read the following;

FYI: I suggest that you look at 'How to Ask Questions the Smart Way' so in the future your queries provide information that will aid us in diagnosis of the problem or query.

Plus scroll down when viewing the thread to see potential help with suggested threads. Another good source is LQ Search engine.

-- PCI:
Peripheral Component Interconnect (PCI) <- 'A standard that describes how to connect the peripheral components of a system together in a structured and controlled way. The standard describes the way that the system components are electrically connected and the way that they should behave. This chapter looks at how the Linux kernel initializes the system's PCI buses and devices.'
pci.ids file <- 'List of PCI ID's to be placed in '/usr/share/pci.ids'. You should update your distribution id's periodically if you change pci devices with newer ones or the distributions 'pc.ids' are dated. If you have 'pciutils' installed then use 'update-pciids' script.
HTH!

Most, if not all, of the machinery necessary to access PCI hardware should already be present on most Linux PC-architecture kernels (and if not, can be easily added). Most likely, you only need to access the existing kernel PCI services from your own driver. That is part of the basis of the whole PCI concept. The online book Linux Device Drivers, 3rd Edition has a full chapter dedicated to PCI drivers.
