Documentation For Writing a Split Driver

[Ryan Riley <rileyrd@purdue.edu>]

I've spent the last few weeks digging around in Xen code and old 
documentation to produce my own simple split driver for 3.0.4-2 to 
handle some logging stuff that I'm doing.  In the process, I quickly 
discovered that the Wiki documentation for adding a new driver to Xen is 
a little lacking.  Is there any interest in me documenting any/all of 
the following and contributing it?
-Creating a backend/frontend skeleton driver and adding it to the kernel.
-Modifying xend and xm to initialize the XenStore for it.  (and hence 
get the probe functions to be called)
-Setting up event channels
-Setting up a ring buffer
-Sharing memory pages between domains (basically the grant tables)

Thanks
Ryan
