130fdd373SVineet Gupta* ARC Performance Counters 230fdd373SVineet Gupta 330fdd373SVineet GuptaThe ARC700 can be configured with a pipeline performance monitor for counting 430fdd373SVineet GuptaCPU and cache events like cache misses and hits. Like conventional PCT there 530fdd373SVineet Guptaare 100+ hardware conditions dynamically mapped to up to 32 counters 630fdd373SVineet Gupta 730fdd373SVineet GuptaNote that: 830fdd373SVineet Gupta * The ARC 700 PCT does not support interrupts; although HW events may be 930fdd373SVineet Gupta counted, the HW events themselves cannot serve as a trigger for a sample. 1030fdd373SVineet Gupta 1130fdd373SVineet GuptaRequired properties: 1230fdd373SVineet Gupta 1330fdd373SVineet Gupta- compatible : should contain 1430fdd373SVineet Gupta "snps,arc700-pct" 1530fdd373SVineet Gupta 1630fdd373SVineet GuptaExample: 1730fdd373SVineet Gupta 1830fdd373SVineet Guptapmu { 1930fdd373SVineet Gupta compatible = "snps,arc700-pct"; 2030fdd373SVineet Gupta}; 21
