Bligh @ 2002-11-26 0:30 UTC (permalink / raw) To: linux-kernel I've been maintaining a patchset for internal use on and off for a while, and have decided to publish it externally. It's based on 2.5.47 partly because I'm slow and boring, but also because I don't particularly want anything from 49, and there's some bleeding edge stuff in it I'd rather not cut myself on. The patchset contains mainly scalability and NUMA stuff, and anything else that stops things from irritating me. It's meant to be pretty stable, not so much a testing ground for new stuff. I'd be very interested in feedback from other people running large SMP or NUMA boxes. Next additions will probably be timer fixes, moving NUMA-Q to subarch, Summit support, and shared pagetables. http://www.aracnet.com/~fletch/linux/2.5.47/patch-2.5.47-mjb3 kgdb Various People The older version of kgdb, not the shiny new stuff in Andrew's tree.

The first one isn't in the tree as yet ... I just haven't been excited enough about speeding up boot speed, to be perfectly honest, seeing as it still takes 5 minutes anyway. It might make more sense once kexec works, and the percentage improvement would become significant. The local_pgdat stuff definitely makes sense ... I'd kind of prefer it to go after the mem_map so I don't have to think about alignment issues so much, but it's been stable for ages, so I guess I'll push it as soon as Linus returns from vacation ...
