0001 * ARC Performance Counters
0002
0003 The ARC700 can be configured with a pipeline performance monitor for counting
0004 CPU and cache events like cache misses and hits. Like conventional PCT there
0005 are 100+ hardware conditions dynamically mapped to up to 32 counters
0006
0007 Note that:
0008 * The ARC 700 PCT does not support interrupts; although HW events may be
0009 counted, the HW events themselves cannot serve as a trigger for a sample.

0011 Required properties:
0012
0013 - compatible : should contain
0014 "snps,arc700-pct"
0015
0016 Example:
0017
0018 pmu {
0019 compatible = "snps,arc700-pct";
0020 };
