| 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 |
| 5 | are 100+ hardware conditions dynamically mapped to up to 32 counters |
| 6 | |
| 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. |
| 10 | |
| 11 | Required properties: |
| 12 | |
| 13 | - compatible : should contain |
| 14 | "snps,arc700-pct" |
| 15 | |
| 16 | Example: |
| 17 | |
| 18 | pmu { |
| 19 | compatible = "snps,arc700-pct"; |
| 20 | }; |
