| * ARC Performance Counters |
| |
| The ARC700 can be configured with a pipeline performance monitor for counting |
| CPU and cache events like cache misses and hits. Like conventional PCT there |
| are 100+ hardware conditions dynamically mapped to up to 32 counters |
| |
| Note that: |
| * The ARC 700 PCT does not support interrupts; although HW events may be |
| counted, the HW events themselves cannot serve as a trigger for a sample. |
| |
| Required properties: |
| |
| - compatible : should contain |
| "snps,arc700-pct" |
| |
| Example: |
| |
| pmu { |
| compatible = "snps,arc700-pct"; |
| }; |
