hi all,
so i've tried to make a new scheduling policy for linux. i've
called it SCHED_USERFIFO. the intent is basically to allow a process
ask for x amount of processor time out of every y jiffies. (the user
part is in the hope that the administrator can set rlimits on the
amount of percentage of time requested and allow non-priviledged users
to use this policy without being able to complete hang the box).

(mostly i'm just sending a mail because i'm pleased with myself
and want to share and get feedback; hopefully this sort of does what i
say it does too).
thanks,

I think this is really cool and have been wanting to see something like
it for some time. Having low latency application response in regular
user space without hanging the system is the one key thing I think that
has been missing with Linux audio. Allowing settable CPU usage limits
also might allow for apps that don't have built in support for
SCHED_FIFO to be run this way via external utilities. Hopefully what you
have created will get the ball rolling :) Cheers.
