If anyone has any objections, please let me know. ------------------ From: Andre Przywara [ Upstream commit eb7051f756460d7b951e94d9656e31ebb631ba28 ] The Performance Monitoring Unit of the Cortex-A8 cores in the Allwinner A10 SoC is connected to interrupt line 66, not 3. This is shown in the manual (where interrupt 3 is assigned to UART2, also in our .dtsi), but has also been confirmed by triggering an PMU overflow interrupt and inspecting the IRQ controller status registers (from U-Boot). Please note that "perf stat" does not use interrupts, this might explain why this evaded the initial testing.
