* 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"; |
|
};
