But now I also have acpi_throttle (if I don't disable it=20 in /boot/loader.conf): dev.acpi_throttle.0.%desc: ACPI CPU Throttling dev.acpi_throttle.0.%driver: acpi_throttle dev.acpi_throttle.0.%parent: cpu0 dev.acpi_throttle.0.freq_settings: 10000/-1 8750/-1 7500/-1 6250/-1 5000/-1= =20 3750/-1 2500/-1 1250/-1 What do these values tell me? I think that are divisors, but how can I see= =20 which one is used? I remember that some time back I saw at boot time some=20 information about "throttle has xx steps, currently using 100%" or=20 something like that. Can I constrain the divisors, lets say I want to have only 10000, 7500 and= =20 5000? (I know I can limit the lowest frequency cpufreq may use with=20 "debug.cpufreq.lowest=3D310" but then I don't know if it throttles the=20 800MHz mode (thus using high core voltage) or if it throttles the power=20 saving 500MHz mode) And what does this tell me: hw.acpi.cpu.cx_supported: C1/0 C2/10 C3/85 hw.acpi.cpu.cx_lowest: C1 hw.acpi.cpu.cx_usage: 100.00% 0.00% 0.00% Thanks in advance, =2DHarry --nextPart1348763.Exl5Oup1M2 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (FreeBSD) iD8DBQBDOpFkBylq0S4AzzwRAozLAJsH3e15N8+wbUj7B54STTT2ePwAtACfWjnK gstF4hvE8mtqzzu0+M2eGbM= =0U0j -----END PGP SIGNATURE----- --nextPart1348763.Exl5Oup1M2--
