Hello all,
I've noticed (and been a small part of) many discussions over the past
couple of months regarding using Ingo's patches for realtime
preemption. However I've seen no discussion about Con Kolivas'
patches, which I know are used on some systems. Is anyone using these
patches? If so, what has to be done in order to get a working audio
system going using them? For example: When using Ingo's patches on
Debian, one has to build/install the kernel, install the appropriate
patched libpam modules, and make an entry in /etc/security/limits.conf
for members of the audio group.
Do the last two steps still apply
with a -ck kernel?
The last two steps have nothing to do with any kernel patch. They
simply allow non-root users to use realtime scheduling, which is useful
for pro audio no matter what kernel you run.
Con's patches are intended to improve interactivity for gaming and
desktop stuff where everything runs at the same priority and the
scheduler has to basically guess who to give the CPU to. They should
have no effect on pro audio applications, which explicitly request a
high-priority scheduling class.
