Im 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
Because With RT patch I can choose on menuconfig Preemption Model 5 choices
(No preempt, Voluntary and low latency , preemptible kernel or fully
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
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 µs) with a low
