I'm trying to get the hardware performance counters (PMU) going on 64-bit-pi3 with upstream Linux, which involves having the proper PMU Interrupt settings in the device-tree file. Is there documentation available on what these settings should be for pi3?
For example, on a similar architecture they have something like this:
compatible = "arm,cortex-a53-pmu";
interrupts = <9>, // IRQ_TYPE_LEVEL_HIGH
<10>, // IRQ_TYPE_LEVEL_HIGH
<11>, // IRQ_TYPE_LEVEL_HIGH
<12>; // IRQ_TYPE_LEVEL_HIGH
interrupt-affinity = <&cpu0>, <&cpu1>, <&cpu2>, <&cpu3>;
