no automated tests in the CI yet, but I already discussed this with
Philippe.

Plan is to move latmus into 'evl test' as already done with hectic.
Combined with the backround stress changes this would allow similar
latency tests as in x3.

I will try to jump back to this topic as soon as I finished polishing of
the riscv patches.

Best,
Tobias
