hello,
I would like to map (Read/Write) pages owned by a HVM guest from my Dom0 Linux kernel module. I have access to the "machine frame numbers" of these pages. 1. What is the right interface to do this? kmap needs 'struct page' ptrs which I doubt exist for pages owned by a HVM guest. Is there a hypercall to do this then? 2. Do I need to modify the HVM behavior in any way for this? (e.g., load a driver in the guest that will setup grant tables?). I need to keep my guest "pure HVM". thanks, ./satya _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
