multiblitz Posted October 10, 2022 Share Posted October 10, 2022 Sorry to ask such a beginner question, but I am still learning about Armbian... When I install debian Kernels from Kernel.org myself, I find this in my source-folder of the distro which I created when unzip/tar the Kernel. But as Armbian does this in the backround for me...where is this folder ? RTLA is a new tool to use osnoise tracer and needs to be compiled from source. https://lwn.net/Articles/869563/ THX 0 Quote Link to comment Share on other sites More sharing options...
Igor Posted October 10, 2022 Share Posted October 10, 2022 So far this is only planned: https://armbian.atlassian.net/browse/AR-1283 But as we pack kernels for many distro and as we cross-compile, this might cause some troubles. This is further complicating as we provide 56 different kernel binaries ... (that number will certainly go down). Welcome! 0 Quote Link to comment Share on other sites More sharing options...
multiblitz Posted October 12, 2022 Author Share Posted October 12, 2022 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... 1 Quote Link to comment Share on other sites More sharing options...
