I'm pleased to announce the v3.18.7-rt1 patch set. It was running over the weekend on my x86 box and was still alive this morning. However it is still the first release for the v3.18 -RT series. I haven't follow the mailing list or commented / applied any patches from the list for -RT while being busy getting this release done (except one patch I needed to have anyway). This is about to change. I will try to go through my RT-inbox before doing the next release. Changes since v3.14.25-rt22 - rebased to v3.18 - Added "Work Simple" from Daniel Wagner. I needed it for cgroup's RCU handling. - "timers: do not raise softirq unconditionally" has been reverted. It has been added to optimize the FULL NOHZ case on CPUs which could avoid a softirq / timer wake up. Its been reverted because it breaks the switch to highres. - added a few patches to get MQ-BLK and cgroups working. Known issues: - bcache is disabled. - lazy preempt on x86_64 leads to a crash with some load. - 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 measuring the performance of the individual implementation.
