you are absolutely right. I can use very large buffers; however there
are two things: I was using quite large ones (but not the immense ones you
quoted)
but say 8192 samples, and I was still getting dropouts. The larger
the buffer the longer the dropouts were lasting for. Yes, I can try

Ok; My suggestion would then be for us to test allowing
RTPRIO to 99 (the max value), if possible, so we can
test its impact. Then it will be possible to test lower
priorities to see what would be a reasonable limit.
There has also been a question of testing stronger
RT kernel patches in future re

/etc/security/limits.conf is simply one vehicle (specifically, the one
used by PAM) for getting a uid-0 process (hence a process w/

Is that documented? I don't see it in man page. I can try it, if
I have a code example (says there it does not take a priority
value, so is it just a matter of setting the policy?)

As noted in a conversation with Michael,
Aren't these priorities the same ones set in /etc/security/limits.conf?
Or are they set by other means?

According to "man sched_setscheduler" you want either CAP_SYS_NICE or a
non-zero RLIMIT_RTPRIO and giving these to you means that you can
hardlock the machine anytime by busywaiting. Audio performance is
clearly important to us in this release -- probably more important than
stopping random malicio

Here is what I have:

*** Topic for #olpc: Web support: http://forum.laptop.org | IRC
support: #olpc
Sorry if I was not clear. Here is the code that currently fails
under rainbow:
/* set scheduling policy and priority */
if (priority > 0) {
p.sched_priority = priority;
if (sched_setscheduler(0, SCHED_RR, &p) != 0) {
csound->Message(csound,"csound: cannot set scheduling po
But as it is, if you are playing MIDI or audio through an Activity launched
by rainbow, there is no way AFAIK you can renice it. The
code I am testing was set to either change scheduler priority
or to renice the process. None is possible.
Note that what I am proposing here would not affect you,
