StarFive Dubhe-90 supports raw event id 0x00 - 0x22. The raw events are enabled through PMU node of the DT binding.
Example of PMU DT node: pmu { compatible = "riscv,pmu"; riscv,raw-event-to-mhpmcounters = /* Event ID 1-31 */ <0x00 0x00 0xFFFFFFFF 0xFFFFFFE0 0x00007FF8>, /* Event ID 32-33 */ <0x00 0x20 0xFFFFFFFF 0xFFFFFFFE 0x00007FF8>, /* Event ID 34 */ <0x00 0x22 0xFFFFFFFF 0xFFFFFF22 0x00007FF8>; };
