1 * ARC Performance Monitor Unit
3 The ARC 700 can be configured with a pipeline performance monitor for counting
4 CPU and cache events like cache misses and hits.
7 * ARC 700 refers to a family of ARC processor cores;
8 - There is only one type of PMU available for the whole family;
9 - The PMU may support different sets of events; supported events are probed
10 at boot time, as required by the reference manual.
12 * The ARC 700 PMU does not support interrupts; although HW events may be
13 counted, the HW events themselves cannot serve as a trigger for a sample.
