Hi Ingo, an outcome from the previous discussion about a virtual sched_clock() on s390 was that scheduler_tick() should also be called based on virtual time. The second patch changes the scheduler_tick() call to only happen after a tick passed for the virtual cpu.
The patches cause nothing obvious to break, numbers from top look sane but I've seen something strange... For a simple make -j6 workload top reports processes very often to be in state <defunct>. Thats' not terribly wrong since this can happens also without the patches but I wonder if this indicates that the scheduler behaves badly and does less often schedule the parent processes that gathers the waiting zombie processes? Are there any indicators in the sched_debug output that I could look for?
