| From | Andrea Arcangeli <> | Subject | [PATCH 15/40] autonuma: knuma_migrated per NUMA node queues | Date | Thu, 28 Jun 2012 14:55:55 +0200 |
| |
This implements the knuma_migrated queues. The pages are added to these queues through the NUMA hinting page faults (memory follow CPU algorithm with false sharing evaluation) and knuma_migrated then is waken with a certain hysteresis to migrate the memory in round robin from all remote nodes to its local node.
The head that belongs to the local node that knuma_migrated runs on, for now must be empty and it's not being used.
