* ARC Performance Monitor Unit
|
||
|
|
|
||
|
|
The ARC 700 can be configured with a pipeline performance monitor for counting
|
||
|
|
CPU and cache events like cache misses and hits.
|
||
|
|
|
||
|
|
Note that:
|
||
|
|
* ARC 700 refers to a family of ARC processor cores;
|
||
|
|
- There is only one type of PMU available for the whole family;
|
||
|
|
- The PMU may support different sets of events; supported events are probed
|
||
|
|
at boot time, as required by the reference manual.
|
||
|
|
|
||
|
|
* The ARC 700 PMU 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-pmu"
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
pmu {
|
||
|
|
compatible = "snps,arc700-pmu";
|
||
|
|
};
