Subject: [patch] voluntary-preempt-2.6.9-rc2-mm1-S1
Date: Sun, 19 Sep 2004 14:26:18 +0200 [thread overview]
Message-ID: <20040919122618.GA24982@elte.hu> (raw)
In-Reply-To: <20040909061729.GH1362@elte.hu>
i've released the -S1 VP patch:
http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc2-mm1-S1
NOTE: this patch is against Andrew's -mm tree and the VP patchset will
stay based on -mm until the merging process has been finished.
to get a 2.6.9-rc2-mm1-VP-S1 kernel, the patching order is:
http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.8.tar.bz2
+ http://kernel.org/pub/linux/kernel/v2.6/testing/patch-2.6.9-rc2.bz2
+ http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.9-rc2/2.6.9-rc2-mm1/2.6.9-rc2-mm1.bz2
+ http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc2-mm1-S1
Changes relative to -S0:
- lots of merging. A good chunk of the VP patch latency breakers and
support patches are in -mm already.
- integrated my 'preemptible big kernel lock' patch into VP. This makes
all BKL code preemptible while keeping correctness. A new debugging
infrastructure has been added to catch code that might use the BKL
in an unsafe way. If the debugging check triggers it will print
messages like:
using smp_processor_id() in preemptible code: bash/1020
please report such messages and backtraces to me. Most of the messages
i've fixed so far were false positives, but one bug has been caught
already via this.
Also, this BKL patch allowed the removal of two questionable
latency breakers: the tty.c and the DRM BKL relaxation hack.
- fixed an SMP hardirq redirection bug - IRQ threads could be bound to
multiple CPUs resulting in potentially illegal preemption of hardirq
contexts.
- temporarily dropped the ppc/ppc64 GENERIC_HARDIRQS changes, they broke
and i cannot test them.
Reports, comments welcome,
Ingo
