[Xen-devel] back/frontend drivers HelloWorld

[Anton Korenyushkin <tiger@xxxxxxxxxxxxxx>]

Hi,

I'm trying to write 2 simple xen0/xenU modules, which only transfer string 
"Hello world" by grant tables interface. But in docs/misc/grant-tables.txt 
there is no explanation of how to transmit grant table reference to another 
domain:
.. gref is then somehow transmitted to domB for use.

I'm reading blkback/front driver's code, but it is too complicated. I've 
understood that i should use message rings for my task (i've read 
docs/misc/blkif-drivers-explained.txt too). But how to get such ring?

May be a simple example of solution such problem exists, so could you point me 
on this example?

Sorry for bad English.
