* 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 upto 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";
|
|
};
