The type should be PERF_TYPE_HARDWARE not PERF_TYPE_RAW. The real hybrid
PMU type can be found in the high 32 of attr.config.

/*
 * attr.config layout for type PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE
 * PERF_TYPE_HARDWARE:			0xEEEEEEEE000000AA
 *					AA: hardware event ID
 *					EEEEEEEE: PMU type ID


Something as below should work.
