Hi guys,

I=92m trying to compile kernel 3.8 with the last xenomai source.

I want to know some precisions about preempt option. 

Is it useless to patch the kernel with with Xenomai and also with RT patch
from kernel.org?

Because With RT patch I can choose on menuconfig  Preemption Model 5 choice=
s
(No preempt, Voluntary and low latency , preemptible kernel or fully
preemptivekernel)

But if I patch only with xenomai I have just 3 choices of preemptive (No
preempt, Voluntary and low latency)

If patch first with RT and after xenomai I have a lot of Hunk message
(warning and error) but if  I Patch first with xenomai and after RT -> no
problem

 

So my question are they compatible together? Or perhaps choosing fully
preemptive will turn my system unstable.

 

My goal is to catch Interruption with a small latency (50-10 =B5s) with a l=
ow
processor charge
