| Thread-topic: | Passing a grant reference to another domain! |
Hi can anyone point me to the code which passes grant reference between domains? In Mini-OS it doesn't seem to be used and I'm a little clueless where to look for passing of reference. I am aware of the way a grant table is mapped, how to use the ring buffer once you map the shared memory page into your domain using the reference and the domain id, and how to read and write into the xenstored database. However, I'm struggling to understand how we pass the grant reference to a particular domain once you share a page after setting necessary access permissions on the page. Regards, Bhaskar. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
