I assume to test this, we select the deadline scheduler?
No, only the deadline

Thanks a lot!
You're welcome.
Just to make it clear. The purpose of this scheduler is at all costs

Great, thanks. The HZ should make very little difference, except for slightly
lower latencies as you increase the HZ.
It works
beautifully. I also quickly checked that playing mp3

ually at the
current runqueue's priority_level or better. This means that the most latency
they are likely to see is one RR_INTERVAL, and often they will preempt the
current task if it is not of a sleeping nature. This then guarantees very
low latency for interactive tasks, and the lowest latencies
they will preempt the
current task if it is not of a sleeping nature. This then guarantees very
low latency for interactive tasks, and the lowest latencies for the least
cpu bound tasks.
