libeRTy
I'm unveiling a new APT repo for Linux-libre, called libeRTy: https://www.fsfla.org/ikiwiki/selibre/linux-libre/liberty.en.html
It contains .debs of Linux-libre compiled with the PREEMPT_RT patch for those that need a realtime kernel but also want freedom. Hence libeRTy. Get it? :)
Hmm... I'm not sure to understand what PREEMPT_RT patch mean... hmmm.
Then you probably don't need it. :) It's for those that need realtime support. Some use it for audio recording but that's not the only use case.
Little older than Parabola's 4.20 kernels. :)
This is a misunderstanding: Parabola's 4.20 kernel isn't realtime. There is no realtime 4.20 anywhere. The realtime patches are only made against LTS kernel versions. The current stable realtime kernel is based on 4.14 LTS, as can be seen on https://wiki.linuxfoundation.org/realtime/start which has:
Latest Development Version 4.19-rt
Latest Stable Version 4.14-rt
So a 4.19 realtime will be available in the future, but the realtime ones always lag behind the non-realtime ones.
If you check out Parabola's realtime kernel you'lll see it also has 4.14 just like mine: https://www.parabola.nu/packages/kernels/i686/linux-libre-rt/
Although mine is 4.14.93, while Parabola's is still 4.14.78 so the libeRTy repo technically has a newer version than Parabola. :)
