Enable cyclictest:
- test execute cyclictest, retrieve the maximum latency captured inside log and compare it to the
target latency
- cyclictest arguments based on public cyclictest arguments used for intel corei7
https://www.osadl.org/Latency-plot-of-system-in-rack-9-slot.qa-latencyplot-r9s5.0.html?shadow=1
- set default target latency based on 24 us (captured from public cyclictest execution) multiple
by 1.2 (buffer)
- enable user defined target latency by configuring 'RTKERNEL_TARGET_LATENCY' as bitbake config
example, inside local.conf: RTKERNEL_TARGET_LATENCY = "25"
