Subject: [patch] O(1) scheduler, -E1, 2.5.2-pre10, 2.4.17
Date: Tue, 8 Jan 2002 15:32:55 +0100 (CET)
Cc: Linus Torvalds <torvalds@transmeta.com>,
Anton Blanchard <anton@samba.org>,
Davide Libenzi <davidel@xmailserver.org>
this is the latest update of the O(1) scheduler:
http://redhat.com/~mingo/O(1)-scheduler/sched-O1-2.5.2-pre10-E1.patch
http://redhat.com/~mingo/O(1)-scheduler/sched-O1-2.4.17-E1.patch
now that Linus has put the -D2 patch into the 2.5.2-pre10 kernel, the
2.5.2-pre10-E1 patch has become quite small :-)
The patch compiles, boots & works just fine on my UP/SMP boxes.
Changes since -D2:
- make rq->bitmap big-endian safe. (Anton Blanchard)
- documented and cleaned up the load estimator bits, no functional
changes apart from small speedups.
- do init_idle() before starting up the init thread, this removes a race
where we'd run the init thread on CPU#0 before init_idle() has been
called.
