Well is that what this nice/rt thing does? When I was looking to see
if the code was already in the kernel I was kind of paying attention
to what it appeared to do...kind of. It seemed to me that it was all
set up so you could just increase the priority of tasks and tell the
kernel they don't have to be as nice to other programs and not to
necissarily pre-empt them. I would think that it might be beneficial
to just up a program's priority a touch or maybe lower its nice level
a touch so it might run a little smoother at the expense of other
programs.
Does a program on a system with a kernel with the nice-rt 'patch' need
to know about rt scheduling?
Ok, now that I have the kernel and everything set
up and jackd is
running in realtime mode, how do I tell the kernel to do that with
other programs that don't know enough to increase their own
priorities? Is there a wrapper program that will start another
program at an increased priority?
This could be something I should already know, but I haven't ever had
to do it before so I don't.
programs need to be designed for realtime mode. Especially they need to
give up the cpu in periodic intervals to keep the system responsive.
Many programs like games won't even work right when running SCHED_FIFO.
