Subject: [alsa-devel] alsa-utils say -c is sched_idle, but actually set sched_rr (BUG?)
Date: Mon, 2 Dec 2019 16:17:22 +0100 [thread overview]
Message-ID: <20191202151722.GA13104@kelsos> (raw)
Hi,
I'm not subscribed to the list. I was looking for uses of SCHED_IDLE in
software in general when I stubled upon this. Although I have no personal
interest in asla development, I thought it would be nice to report it here.
alsa-project/alsa-utils commit 611249ae26f435429dbe1894e210704a723ee277 says:
alsactl: add --nice and --sched-idle options
The state management can run at low priority, add --nice and --sched-idle
options to set the scheduler.
Everywhere in the code it says SCHED_IDLE *except* for the actual call to
sched_setscheduler() which instead sets the policy to SCHED_RR. I have
looked twice to see that I don't miss anything obvious, and suspect this is
an error, or that there should be a comment that explains this oddity.
Kind regards,
Tommy
