Xen devel - Sep 2006 - getting started with writing block device drivers

Hi,

   I am planning to write a sample block device driver (probably ramdisk) on
Xen. Basically I want to have an hands-on experience about how the I/O is
being transmitted between front end driver and back end driver. And also I
want to see how the ioctls that are issued from guest OSs front end driver
will be transmitted/serviced by back end drivers.

   Could you please give me interface specifications to write a sample block
device driver so that i can see the ioctls and data moving back and forth
between front end and backend drivers?

TIA.,
