Using interrupts to control scheduling decisions in base-hw

[Adrian Hengelhaupt]

Hello,

My task is to implement a preemptive scheduler for a zynq-board. 
Therefore I've tried to figure out how the cpu_scheduler program in 
repos/baseh-hw/run/cpu_scheduler.run works and whether it can be used as 
a foundation for my task.
So, my question is: How can I utilize interrupts in order to make 
subsequent scheduling decisions?

Thanks in advance!

Greetings
Adrian
