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 "ill 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 b
