ARM TI AM3354 @800 MHz, Linux 5.10.47-rt46 (Profile)

Latency plot of system in rack #4, slot #2
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l50000000 -m -n -a0 -t1 -p99 -i400 -h400 -q
Total number of samples: 50 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance
Compare latency of primary with shadow system
Characteristics of the 100, highest latencies:
