Celeron J3160 with enabled Turbo mode stays at 480MHz (lowestsetting) forever and can not lower frequency without Tuebo mode

 Oops. My fault. I've forgot to set cx_lowest to C3 on all cores.
 BTW, these four settings in rc.conf(5)

  performance_cx_lowest
  performance_cpu_freq
  economy_cx_lowest
  economy_cpu_freq

do NOTHING. They are not used ANYWHERE but rc.conf and rc.conf.5!

 Sorry? I could only turn Turbo mode on/off in BIOS before boot.

 BTW, "Turbo mode enabled + dev.cpu.X.cx_lowset=C3 + powerd" works, but
gives only 1601 Mhz, not 2240MHz max:

TURBO ON:
dev.cpu.0.freq_levels: 1601/2000 1600/2000 1520/1900 1440/1800 1360/1700 1280/1600 1200/1500 1120/1400 1040/1300 960/1200 880/1100 800/1000 720/900 640/800 560/700 480/600 420/525 360/450 300/375 240/300 180/225 120/150 60/75

TURBO OFF:
dev.cpu.0.freq_levels: 1600/2000 1520/1900 1440/1800 1360/1700 1280/1600 1200/1500 1120/1400 1040/1300 960/1200 880/1100 800/1000 720/900 640/800 560/700 480/600 420/525 360/450 300/375 240/300 180/225 120/150 60/75

  But I could live with that :-)
