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: http://rt.wiki.kernel.org/index.php/Preemption_Test Regards, -Greg - To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
