i wonder, what's the preferred way to obtain SCHED_DEADLINE privileges
as non-root user?

Hi Tim,

It is still not possible to use sched deadline as a non-root user :-(.

Indeed, but Tim, is this hindering you from experimenting/using
DEADLINE?

it's a showstopper for using it in audio applications, which are running
as user.
audio applications typically use SCHED_FIFO. however they are
rate-monotonic by design, so i wanted to evaluate how SCHED_DEADLINE
behaves here.

Right. Exactly what I started to think about lately as well.

Asking because we might want to have a look at how to relax the current
privileges requirement.

please :)

Anything to try attracting new users. :-P

More seriously, could you please describe in a bit more details your
specific use case? Based on JACK I guess? Is it the application you are
interested into public available somewhere?

Thanks,
