Maybe this page could be of help:
https://wiki.ubuntu.com/RealTime
Anyway there's something i can't get:
Q: What is the difference between an -rt kernel and a -realtime kernel?
A: [...] The main difference is that the -rt kernel should be based on the
Ubuntu source tree [...] On the other hand, the -realtime kernel is a
PREEMPT_RT patched kernel based on the vanilla source tree (not the Ubuntu
source).This kernel will be missing Ubuntu specific code, patches or
security fixes and it isn't guaranteed to be compatible with any external
software (low level utilities, DKMS drivers and so on). It does not use the
same Linux kernel version as the -generic kernel, and so these two kernels
are not aligned
But at the top of this page it says:
The -preempt and -rt kernels are no longer being developed due to lack of
support. Focus has instead turned to the -lowlatency and -realtime kernels
Why do they focus on -realtime kernels which "will be missing Ubuntu
specific code, patches or security fixes and it isn't guaranteed to be
compatible with any external software".
Maybe it's too late here 3:41 am and i'm a bit tired :)
