    device drivers


    1) Do the linux device drivers reside in user space ?
    2) if not, then how can they be a part of kernel address space ?
    3) how do we integrate device drivers with kernel ?
    4) and how do we write a driver in such a way that it gets more protection from user space programs.

    The driver can be made a part of the main kernel, and can be compiled into the kernel image itself, you should google a little to find out.

    Go through Linux Device Drivers by Alexander Rubunio its free ebook online available.
