Webb7 dec. 2024 · simpleperf has used unwinding while recording by default for a long time. And it works well. More time is taken by copying stack, not by the unwinder.

WebbWe can use simpleperf stat --print-hw-counter to show hardware counters (per core) available on the device. On Pixel devices, the number of PMU counters on each core is usually 7, of which 4 of them are used by the kernel to monitor memory latency. So only 3 counters are available. It's fine to monitor up to 3 PMU events at the same time.
