Subject: [PATCH 0/9] RT: balance rt tasks v6
Date: Wed, 24 Oct 2007 09:52:31 -0400	[thread overview]
Message-ID: <20071024134431.7960.41984.stgit@novell1.haskins.net> (raw)

Applies to 23-rt1

Changes since v5:

*) Folded some of the smaller patches together to address feedback
*) Fixed several minor bugs related to PI re-factoring and wakeup paths

I still have yet to make Ingo Oeser's suggestion to the last patch.

At this point, things are looking really really good.  So this is a request to
provide a formal review (if one has not yet been done) and to consider for
inclusion in -rt.

In my testing, cyclictest look great (ran overnight on a 4-way with the max
outlier at 32us), the preempt-test passes with flying colors, and we see a
300% improvement in latency spikes on large SMP systems (16-way is the largest
we have in our small lab).

I will rebase to -rt2 when its available.

You can find the preempt-test here:

Regards,
-Greg
