[ 43.105] (II) VESA: driver for VESA chipsets: vesa

Intel(R) Atom(TM) Processor E3950 @ 1.60GHz, Linux 4.19.37-rt19 (Profile)

Latency plot of system in rack #d, slot #7
Data to construct the above plot have been generated using the RT test utility cyclictest.
Unexpectedly long latencies may be caused by SMIs
Command line: cyclictest -l100000000 -m -n -p90 -i200 -h400 -a0-2 -t3 -q done
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance
The worst-case latency is NOT higher under extreme CPU load.
Results of all systems under extreme CPU load are combined on this summary graph.
The worst-case latency is about 1.10 times higher under graphics load.
Results of all systems with accelerated graphics are combined on this summary graph.
Characteristics of all highest latencies:
