Done, by the way: should be good enough (reduced overhead for non-numa system from ~1MB to ~16kB). I'd like to make the allocation search smarter at some point: avoid exhaustive search of all viable heaps by instead have empty heaps point at the next heap to try (with some tradeoff between accuracy of guidance and cost of maintaining the guidance info; I have some ideas here). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
