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 upto 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};

1* ARC Performance Monitor Unit
2
3The ARC 700 can be configured with a pipeline performance monitor for counting
4CPU and cache events like cache misses and hits.
5
6Note 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.
