I am thinking about providing two APIs for this. 1. KPI void cpu_get_a_m_perf(u_int cpu, uint64_t *aperf, uint64_t *mperf); 2. Userland sysctl dev.cpu.N.aperf_mperf that returns two UQUAD values. But I am not sure where to put the code for both APIs. Adding another device under cpu seems like an overkill. Ideas? Thanks! -- Andriy Gapon
