Subject: [PATCH] 2.4: updated preemptive kernel patch
Date: 30 Mar 2002 13:16:02 -0500 [thread overview]
Message-ID: <1017512162.2941.134.camel@phantasy> (raw)
This is the preemptive kernel patch, supported by MontaVista. Updated
patches for 2.4.18, 2.4.19-pre5, and 2.4.19-pre4-ac3 are now available
at:
ftp://ftp.kernel.org/pub/linux/kernel/people/rml/preempt-kernel
as well as older patches for older kernel revisions.
The only major change aside from the sync up is some simple debug code
that will catch most any preempt_count oddity without much overhead,
courtesy of Andrew Morton. Basically just check the preempt_count for a
non-zero value on do_exit.
Nothing pending in the 2.4 codebase. I have a bunch of changes queued
for preempt-stats which I will get out real soon now. For 2.5, there
are a couple of indirect preempt-related optimizations and lock-fixings
in store soon.
Recent Change Log:
20020328
- simple but complete debug check in do_exit (Andrew Morton)
20020301:
- fix the preempt_count for non-CPU0 idle (George Anzinger)
