I'm pleased to announce the v4.0.4-rt1 patch set. Changes since v3.18.13-rt10 - Rebase to v4.0. - David Hildenbrand's series of decouple of preempt_disable from pagefault_disable is part of the series. While doing the v4.0 I stumbled upon a few things. Therefore I plan to reorder the -RT queue and merge patches where possible. Also I intend to drop PREEMPT_RTB and PREEMPT_RT_BASE unless there is need for it… Known issues: - My AMD box throws a lot of "cpufreq_stat_notifier_trans: No policy found" warnings after boot. It is gone after manually setting the policy (to something else than reported). - bcache is disabled. - CPU hotplug works in general. Steven's test script however deadlocks usually on the second invocation. - xor / raid_pq I had max latency jumping up to 67563us on one CPU while the next lower max was 58us. I tracked it down to module's init code of xor and raid_pq. Both disable preemption while measuring the performance of the individual implementation.
