1 | * ARC Performance Counters |
2 | ||
3 | The ARC700 can be configured with a pipeline performance monitor for counting | |
4 | CPU and cache events like cache misses and hits. Like conventional PCT there | |
da67e68c | 5 | are 100+ hardware conditions dynamically mapped to up to 32 counters |

7 | Note 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. | |

11 | Required properties: | |
12 | ||
13 | - compatible : should contain | |
14 | "snps,arc700-pct" | |

16 | Example: | |

18 | pmu { | |
19 | compatible = "snps,arc700-pct"; | |
