The priority boosting chain is now instantaneous again (and not wakeup/scheduling based) - but the previous list-walking hell has been avoided via the clever use of plists. Plus many other changes and lots of cleanups to the rt-mutex proper. - the rt-SLAB code got reworked too - hopefully for the better. - there's also a completely new PI-futex approach included, ontop of the robust-list futex feature. All combinations of PI and robustness are supported: default non-robust non-PI futexes, robust+PI, !robust+PI, PI+!robust futexes. - new latency tracer feature: print every function call done by the kernel to the console - useful to debug early bootup hangs or other nasty bugs. - plus zillions of bugfixes (and no doubt new regressions). to build a 2.6.16-rc6-rt1 tree, the following patches should be applied: http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.15.tar.bz2 http://kernel.org/pub/linux/kernel/v2.6/testing/patch-2.6.16-rc6.bz2 http://redhat.com/~mingo/realtime-preempt/patch-2.6.16-rc6-rt1 Ingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
