looking at the 200lines patch... it seems to activate RT_GROUP_SCHED
if anybody know how the system needs to be configured, so that jackd
runs with this option on, it might be nice if you told us.
if we really get kernels with this turned on soon, we better be prepared.
Hi
Aparently a new, 200 lines kernel patch have been buzzing the web lately,
supposedly it should provide a much more responsive desktop.
But this userspace alternative should be even better:

Anyone heard of it, tried it and/or has any thoughts whether it has anything
to offer on a DAW?
it doesn't look terribly relevant because a DAW is going to schedule
most threads that matter with SCHED_FIFO. these threads will be
scheduled by a different set of rules than SCHED_OTHER (i.e. most of
the desktop threads, and the scheduling class that is affected by the
patch). that's not to say it might not still make things feel a bit
better, but it won't really make lower latencies possible etc. etc.. I
think. _______________________________________________
