---------- Forwarded message ---------- From: Neo <aravind.tron...@xxxxxxxxx> Date: Jun 18, 2:33 pm Subject: Xen - Page transfer To: vmkernelnewbies Hi, I am trying to implement a page transfer mechanism in Xen. I am using grant tables to do this. But I am confused as to who has to acquire the grant reference whether the module who is transferring the page(Dom 0) or the module who is requesting the page (Dom x). Is it sufficient to do grant_table_op(gnttab_transfer_page, &op, n) Or should I also do gnttab_grant_foreign_transfer (domid, pfn) ??? Once i do transfer from the Dom 0 should I explicitly map it in Dom x? I also know that Dom x has to advertise his interest in recieving this page, but should Dom x map it ??? can any one point me to a sample code snippet of finding out the sequence of calls ?? I just need some help here..... Thanks in advance Aravind _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
