Here they are... http://www.joq.us/jack/benchmarks/sched-isoprio http://www.joq.us/jack/benchmarks/sched-isoprio+compile I moved the previous runs to the sched-fifo* directories where they belong. For convenience, I moved all the summary data logs here... http://www.joq.us/jack/benchmarks/.SUMMARY Unfortunately, these corrected tests do not compare favorably with the earlier sched-fifo runs (mistaken or otherwise). I wanted to believe the problem was just a matter of priorities, but evidently it is not. In fact, for this test the priority scheduler does not really help at all (though I believe it will for other things). The max delay numbers are still all over the place... ...benchmarks/sched-iso...

I still don't think it will make any difference. But my intuition isn't working very well right now, so I need more data. I still wonder if some coding error might occasionally be letting a lower priority process continue running after an interrupt when it ought to be preempted. -- joq - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
