Hi all, The next obvious step for paravirt_ops seems to me to be higher-level mmu operations: from reading the VMI patches it seems to do flushing, whereas Xen opts for batching. In the spirit of ops structures, this would be done by putting higher-level operations into the ops structure, and batching done by the op itself (perhaps with a default implementation for those too lazy to implement it). At this point we run into the brick wall of my ignorance: Chris, Zach, anyone, are there any obvious interfaces from a Linux POV? Thanks! Rusty. -- ccontrol: http://ccontrol.ozlabs.org
