| Thread-topic: | sharing memory between qemu and domu without grant tables or vmexits... |
Is it possible to share a page of memory between qemu in dom0 and domu without using grant tables and without domu access to that page causing a vmexit? To set up a custom kernel debug dll under windows I need to load very early, much earlier than my PV drivers. To have any hope of usefully increasing the speed over serial port debugging I need to be able to transfer data faster than 1-byte-per-vmexit... Thanks James _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
