future of -rt kernels for realtime audio

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I've been using -rt kernels since 2.6.29 because I do realtime audio
on my laptop.

The audio stability has been steadily improving since, and now I find
that I can use 2.6.34 without the -rt patch and achieve the same
stability as 2.6.33-rt - well, my latency requirements aren't that
high, I just need to maintain 8.9ms completely stable, however before
.34 it would be impossible without the -rt patch.

So out of curiosity, what changed for .34? According to [1], on .33
Raw Spinlock Annotation was introduced in the mainline kernel.
However, as said above, I can't get the same performance than with
.34.

I remember that I read somewhere that the one the biggest problems
with latency requirements was the use of the BKL. Do you think there
will be a significant improvement of latency (in specific cases of
course) with the scheduled removal of BKL for 2.6.36?

Thanks for the help,
Pedro
