After having a looong chat with the guys from linux4audio and reading
tons of posts in ccrma forum, I must say .....
Idea with an rt-kernel for netbooks ....... DISMISSED .... it simply
makes no sense.
Those guys mostly use gentoo and build their own kernel for years now
and they gave me the following hints, that also can be found in
discussions of other distributions:
1) the kernel (without preemption-patch) should have
Processor type and features>> Preemption Mode>> Complete Preemption
(Real-Time)
This is already enabled in kernel-tmb
Processor type and features>> Timer frequency>> 1000 HZ
This is already enabled in all -desktop kernels
General setup>> RCU Subsystem>> RCU Implementation (Preemptable tree-based
hierarchical RCU)
This is already enabled in kernel-tmb
Proccesor Type and features >> Tickless System (Dynamic Ticks) should
be excluded
This one you can get by booting with "nohz=off" on the kernel command line.
