I am reposting an updated patch for accessing NUMA cell available memory, and posting the initial patch for accessing NUMA topology information. Again, this code is primarily untested. I am looking for comments in parallel with the testing I will begin tomorrow. These patches prereq Daniel Veillard's initial framework patch: https://www.redhat.com/archives/libvir-list/2007-September/msg00069.html [PATCH 1/2] - add capability to access free memory information on each NUMA cell. [PATCH 2/2] - add capability to access topology information (cell to cpu mapping) for each numa cell. I have not yet added the full node available memory API call that was discussed on the list. As I understand the NUMA code is more urgent. If you would like to get this code in too, I can create another patch for that. My focus for the moment is testing.
