description: |
  The Samsung Exynos542x SoC has a NoC (Network on Chip) Probe for NoC bus.
  NoC provides the primitive values to get the performance data. The packets
  that the Network on Chip (NoC) probes detects are transported over the
  network infrastructure to observer units. You can configure probes to capture
  packets with header or data on the data request response network, or as
  traffic debug or statistic collectors. Exynos542x bus has multiple NoC probes
  to provide bandwidth information about behavior of the SoC that you can use
  while analyzing system performance.
