* ARC HS Performance Counters
|
|
|
|
The ARC HS 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.
|
|
It also supports overflow interrupts.
|
|
|
|
Required properties:
|
|
|
|
- compatible : should contain
|
|
"snps,archs-pct"
|
|
|
|
Example:
|
|
|
|
pmu {
|
|
compatible = "snps,archs-pct";
|
|
};
