Thanks for the fast reaction...as I said...I am an armbian-beginner and in the process to learn what you provide..and that is already great stuff.
 
In the meantime I learned that armbian-config has the option to install a kernel source...tried that...and BINGO ! Now we have the needed source-files. RTLA install procedure is than:
 
cd /usr/src/linux-source-5.19.14-rockchip64/tools/tracing/rtla
apt install python3-docutils -y
apt install pkg-config -y
apt install git -y
git clone git://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git
cd libtraceevent/
make
sudo make install
cd ..
git clone git://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git
cd libtracefs/
make
sudo make install
cd ..
make
sudo make install
 
great stuff.. now I can compare osnoise effects of different kernel configs and software setups on arm as I can already on x86...which is exptremely helpful to observe tickless mode and otimize for PCM-audio-playback in highest quality...
