I have the following kernels installed:
- linux-zen (Zen)
- linux-rt (RealTime)
- linux-hardened (Security Hardened)
- linux-lts (Long Term Support)
- linux-tr-lts (Realtime LTS)
When I boot up, I try the different kernels from time to time just to see if anything interesting happens. It never does.
My question: How do I actually physically notice the difference between these kernels? If I use RT, does Firefox spawn quicker (in my testing, no, not really)?
What are some use cases when I can really see the difference in these kernels?
Yes, aircraft for example. If the pilot says “gear down”, the gear must go down in short order. You can’t say “well I think I’ll check the airspeed sensor a few times first”.
due to DO-178C requirements, Linux can’t be used there… yet.
That’s pretty cool. Seems like a big undertaking tho
But it’s used in PES (Passenger Entertainment Systems) at least.
