Thanks for the reference! From reading that, it seems as though the sysctl-exposed functionality matches the dmesg.boot description (speed controls only available on cpu 0): dev.cpu.0.%desc: ACPI CPU dev.cpu.0.%driver: cpu dev.cpu.0.%location: handle=\_PR_.CPU0 dev.cpu.0.%pnpinfo: _HID=none _UID=0 dev.cpu.0.%parent: acpi0 dev.cpu.0.freq: 2933 dev.cpu.0.freq_levels: 2933/90000 2799/83000 2666/77000 2533/71000 2399/65000 2266/59000 2133/53000 1999/46000 1866/40000 1733/34000 1599/28000 1466/22000 1333/16000 1199/10000 1049/8750 899/7500 749/6250 599/5000 449/3750 299/2500 149/1250 dev.cpu.0.cx_supported: C1/3 C2/205 C3/245 dev.cpu.0.cx_lowest: C1 dev.cpu.0.cx_usage: 100.00% 0.00% 0.00% last 311us dev.cpu.1.%desc: ACPI CPU dev.cpu.1.%driver: cpu dev.cpu.1.%location: handle=\_PR_.CPU1 dev.cpu.1.%pnpinfo: _HID=none _UID=0 dev.cpu.1.%parent: acpi0 dev.cpu.1.cx_supported: C1/3 C2/205 C3/245 dev.cpu.1.cx_lowest: C1 dev.cpu.1.cx_usage: 100.00% 0.00% 0.00% last 191us Since the cpufreq man page lists the inability to set the frequency of different CPUs differently, perhaps this isn't a bug at all?
