74 On Pixel devices, the number of PMU counters on each core is usually 7, of which 4 of them are used
75 by the kernel to monitor memory latency. So only 3 counters are available. It's fine to monitor up
76 to 3 PMU events at the same time. To monitor more than 3 events, the `--use-devfreq-counters` option
77 can be used to borrow from the counters used by the kernel.
