* ARC Performance Counters
The ARC700 can be configured with a pipeline performance monitor for counting
CPU and cache events like cache misses and hits. Like conventional PCT there
are 100+ hardware conditions dynamically mapped to upto 32 counters
Note that:
* The ARC 700 PCT does not support interrupts; although HW events may be
counted, the HW events themselves cannot serve as a trigger for a sample.
Required properties:
- compatible : should contain
"snps,arc700-pct"
Example:
pmu {
compatible = "snps,arc700-pct";
};

* ARC Performance Monitor Unit
The ARC 700 can be configured with a pipeline performance monitor for counting
CPU and cache events like cache misses and hits.
Note that:
* ARC 700 refers to a family of ARC processor cores;
- There is only one type of PMU available for the whole family;
- The PMU may support different sets of events; supported events are probed
at boot time, as required by the reference manual.
* The ARC 700 PMU does not support interrupts; although HW events may be
counted, the HW events themselves cannot serve as a trigger for a sample.
Required properties:
- compatible : should contain
"snps,arc700-pmu"
Example:
pmu {
compatible = "snps,arc700-pmu";
};
