1* ARC Performance Counters 2 3The ARC700 can be configured with a pipeline performance monitor for counting 4CPU and cache events like cache misses and hits. Like conventional PCT there 5are 100+ hardware conditions dynamically mapped to up to 32 counters 6 7Note that: 8 * The ARC 700 PCT does not support interrupts; although HW events may be 9 counted, the HW events themselves cannot serve as a trigger for a sample. 10 11Required properties: 12 13- compatible : should contain 14 "snps,arc700-pct" 15 16Example: 17 18pmu { 19 compatible = "snps,arc700-pct"; 20}; 21
