Hi friends,
can any1 point me to a good linux memory management stuff. Actually i
want to know the conversion of virtual to physical address and when u
need to do it. I am seeking to do some dma from the host memory to an
ethernet device. I have registered my own device data structures,
while booting my device. i.e it seeks all the memory it needs at
startup. later i put the data to the device specific data structures &
ring a doorbell register later upon which the device picks up the
data. This is my plan. But i am facing some problems during dma time.
So can someone throw some light as to how to do this in a generic way
so that later i can customise it?

For getting detail and in-depth information on DMA and memory
management just get the book "Understanding the Linux VM" by Mel
Gorman. You can find its pdf version by just google for it. or get
from the link http://www.csn.ul.ie/~mel/projects/vm/guide/pdf/understand.pdf
