After updating to v157, it’s also update the kernel to a new version 4.9.52 not RT of the Kernel.
So I try to rerun the command to install the RT kernel and it’s revert back to the v4.9.44-rt30-v7+.
Is it ok to go back to the previous version of kernel or there may be problems?
Will new versions of the RT kernel be released in the future?
RT is currently in testing, we will provide updated version in the future, once we have integrated an option in DietPi, that allows users to select RT/NON-RT kernel.
Just what it says: “An option in DietPi that allows users to select RT/NON-RT kernel”, without having to manually build the kernel with RT patches". An RT kernel would be interesting for audio applications.
I just recognised that there are RT kernel branches for 4.19 and 4.14. Probably there were related packages in the past which are the reason for this topic. But those are not present for current Linux versions. I think it is some build flags which make it suitable for RT applications.
No I mean that probably with recent Linux versions, there are no changes to the Linux source code required anymore to enable RT capabilities, hence no reason to have a dedicated RT source branch. But at least build flags will need to be adjusted to optimise it for RT applications. And the single build/package that is distributed surely does not have them set.
