0013 description: |
0014 The Samsung Exynos542x SoC has a NoC (Network on Chip) Probe for NoC bus.
0015 NoC provides the primitive values to get the performance data. The packets
0016 that the Network on Chip (NoC) probes detects are transported over the
0017 network infrastructure to observer units. You can configure probes to capture
0018 packets with header or data on the data request response network, or as
0019 traffic debug or statistic collectors. Exynos542x bus has multiple NoC probes
0020 to provide bandwidth information about behavior of the SoC that you can use
0021 while analyzing system performance.
