1 * ARC Performance Monitor Unit 2 3 The ARC 700 can be configured with a pipeline performance monitor for counting 4 CPU and cache events like cache misses and hits. 5 6 Note that: 7 * ARC 700 refers to a family of ARC processor cores; 8 - There is only one type of PMU available for the whole family; 9 - The PMU may support different sets of events; supported events are probed 10 at boot time, as required by the reference manual. 11 12 * The ARC 700 PMU does not support interrupts; although HW events may be 13 counted, the HW events themselves cannot serve as a trigger for a sample. 14 15 Required properties: 16 17 - compatible : should contain 18 "snps,arc700-pmu" 19 20 Example: 21 22 pmu { 23 compatible = "snps,arc700-pmu"; 24 };
