Linux 6.12 now has 4 preemption models:

1) No Forced Preemption (Server)

2) Voluntary Kernel Preemption (Desktop)

3) Preemptible Kernel (Low-Latency Desktop)

4) Fully Preemptible Kernel (Real-Time)

For desktop workstation users #2 is recommended but
if one needs millisecond latency then choose #3.

#4 is only appropriate for real-time audio/visual
processing, but #3 may suffice for this role as well.

Usually #4 would be appropriate for embedded industrial
control systems. Ordinary users would not benefit much.

Question: How many preemption models are available to
Microslop Winblows users?

Answer: Someone with symbrachydactyly could count them
on the fingers of one hand:

Haaaaaaaa, ha, ha, ha, ha, ha, ha, ha, ha!
