[Xen-devel] [PATCH 00 of 16] credit2: Scale to multiple sockets
This patch series allows credit2 to scale reasonably past one socket.
The to key things it introduces are:
* Code to detect cpu topology, and create one runqueue per socket
* A first-cut at a load-average based load balancer
Quick descriptions below:
01: Make some debug messages quieter.
02-03: Clean up some of the per-cpu runqueue lock pointer code. This
is the only part of the patch that touches code outside the credit2
scheduler.
04-07: Infrastructure for having multiple sockets, including hooks for
load calculation
08: Detect socket layout, make one runqueue per socket
09-13: Infrastructure for load-balancing, including load averages for
runqueues and sockets
14: A load-average-based balancer
15: Refinement on when to balance
16: Debug key output
