Hello,

yes, suse kernel (since 8.1) already includes most of the
necessary changes. some parts are missing but they are on
the rare code path, which has been not audited quite well,
anyway.
What does this mean?
- If I need low latency, I can use a SuSE kernel without
recompiling it? And don't have to bother about switching LL on
and off? (There is neither the kernel-config option "Low
Latency" nor somethin in /proc to switch it on)
- I can use the SuSE sources, but have to recompile? (with what
options?)
the LL patch is a easy change. but it's pretty
difficult to
apply the preempt patch on the heavily modified kernel like
suse's and redhat's.
if you really need PE, try 2.6 kernel. it's better
maintained.
What do I need the PE patch for?
I am still working at an answer to KEYBOARDS and will detail in
a later letter. For now only some questions:
- (like said above) to get low-latency on a stock SuSE 8.2, I
don't have to bother with the kernel and any configuration
(setting something in /proc) -- right?
- what is the reason for starting the init without full
capabilities? (to use jackstart, I have to rebuild the kernel
with all capabilities set for init -- but this was straightforward)
- when running jackd (from the very nice qjackctl with
jackstart) together with ardour and jamin, I get a number of
xruns. The same configuration under windowmaker doesn't seem to
have this problems. (I am trying to move my CD-mastering from
MacOS-X and Spark LE to Linux)
- the first thing to start with "real" audio under KDE is to
deactivate aRts -- right?
