* Samsung Exynos NoC (Network on Chip) Probe device
|
|
|
|
The Samsung Exynos542x SoC has 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.
|
|
|
|
Required properties:
|
|
- compatible: Should be "samsung,exynos5420-nocp"
|
|
- reg: physical base address of each NoC Probe and length of memory mapped region.
|
|
|
|
Optional properties:
|
|
- clock-names : the name of clock used by the NoC Probe, "nocp"
|
|
- clocks : phandles for clock specified in "clock-names" property
|
|
|
|
Example : NoC Probe nodes in Device Tree are listed below.
|
|
|
|
nocp_mem0_0: nocp@10ca1000 {
|
|
compatible = "samsung,exynos5420-nocp";
|
|
reg = <0x10CA1000 0x200>;
|
|
};
