learning about linux drivers for 2.6 kernel

See the linux kernel mode programming guide for 2.6:

Cheers, Guy

There's also Linux Device Drivers, Third Edition, O'Reilly 2005.

It may be easier to read than the LDP's guide.

Regards, Guy

I read both those docs many times, now I would like to write some real driver/module for Linux, I have Linux PC also, also I have two more extra NIC cards, can somebody suggest me how can I write something it works practically (I have Linksys router, can I replace something by implementing on my linux PC), I need to see my own printk's in /var/log/messages, also I should get some shelf satisfaction that not only I know theoritaically, also practically, I can tell somebdoy that I did some some practically in Linux, so that I can get some work,

Can some expert suggest me how can I do something practically or for the current NIC driver (or bridge files) can I make some changes, or can I add extra proc commands so that I can look those commands working or not, please suggest me, Million/Billion thanks for you guys. Mainly I like Networking/Routing part. Just give me a hint to write something in kernel.

Sorry for my poor explanation.

Is there any Linux Guru (Pundit) was there who can answer my above question. Thanks in advance.

No guru, but I have also gone down this road in the past. If you are specifically wanting to do something interesting under Linux, with a NIC, at the driver level, check out the following link:

In it, the author walks through the development of a custom NIC driver step-by-step (from the point of accessing the NIC over the PCI bus). Its very detailed, and was great when I was getting started. Note: It is for the 2.4 kernel, but the vast majority of the code can be utilized under 2.6 (the driver model hasn't really changed THAT much, and if you have even written the most basic 2.6 driver, you should be able to get this running under 2.6).

John, I read this link, it is very interesting (if I have my own Intel NIC card, can I do any type of programming with this NIC card), do you have any links about some real module/kernel module programming, also some application which interacts with that module. Thannks in advance.

Thanks.
