Xen devel - Apr 2005 - ioctl - daemon in xen0 and a front-end driver in guestOS

Hi
I want to configure my  front-end driver  from a daemon running in xen0.
The front-end-driver  eventually will transfer bulk data(share page ring
or grant table ??) to my daemon running in xen0(via a back-end driver). 

I am using 2.0.5 source base.

I could not find a one simple document except for
blkif-drivers-explained.txt in docs/misc.

I can spend more time (have a small deadline to meet) to figure out. But
wonder if there is really something available which can help me write an
ioctl(alternative?) from a daemon in xen0 to front end driver and get
bulk data to my daemon.

May be few words from XEN experts will help me to deliver something
ontime.

Best Regards & thanks very much in advance.
