- * 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";
- };
