Date: Tue, 23 Oct 2007 12:50:23 -0400 From: Gregory Haskins <ghaskins@...ell.com> To: linux-rt-users@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Gregory Haskins <ghaskins@...ell.com>, Steven Rostedt <rostedt@...dmis.org>, Dmitry Adamushko <dmitry.adamushko@...il.com>, Peter Zijlstra <a.p.zijlstra@...llo.nl>, Ingo Molnar <mingo@...e.hu>, Darren Hart <dvhltc@...ibm.com> Subject: [PATCH 00/13] Balance RT tasks v5 This is version 5 of the patch series against 23-rt1. There have been numerous fixes/tweaks since v4, though we still are based on the global rto_cpumask logic instead of Steve/Ingo's cpuset logic. Otherwise, it's in pretty good shape. Without the series applied, the following test will fail: ftp://ftp.novell.com/dev/ghaskins/preempt-test-latest.tar.bz2 After it is applied, it will pass. NOTE: it appears that the series also introduces wake-latency spikes that are not present in the baseline code, so this is still "RFC" quality. However, the baseline scheduler also violates priority order, so its hard to determine if the numbers translate apples to apples. These issues are still under investigation, but I am sharing the series now so that Steven Rostedt and Darren Hart can have access to my current tree. The issues appear to be caused by some other strange scheduling decisions (such as running the idle thread while we are busy).
