Back on Sunday 01 May 2005 09:47 pm, Noah Roberts was like:
I am compiling 2.6.11 and having trouble finding the
patches I am
supposed to use for low latency. In scouring the internet I find old
references to a Realtime LSM, a Low Latency patch, and the
Pre-emptable kernel patch. The later is included in the kernel now
and I turned it on. The low-latency patch seems to only be findable
as a patch to 2.4. The newest LSM is from a year ago.
The user list website has a how to but it seems rather dated:
http://www.djcj.org/LAU/guide/Low_latency-Mini-HOWTO.php3
Last update 2 years ago.
What are the current set of patches you use and where are they? More
importantly, how to you ready a CURRENT kernel for use with audio and
where is the HOWTO on that?
Thanks.
The current 2.6 kernel is pretty good on it's own. If you're looking to patch
it further though, there are only really two patches you need:
1) Ingo's realtime-preempt patchset
http://people.redhat.com/mingo/realtime-preempt/
2) the current realtime-lsm patch. it can be found in the broken out patches
from the mm patchset
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.12-rc3/2…
I'm currently using a kernel with the Gentoo patchset applied (for added
stability and bug fixes), with these two added on top (for lower latency and
the LSM capability). Works fine.
