Nate, Thanks for the hard work on cpufreq! I am running an AMD64 3400 CPU in my lappy, and I don't see any difference in dev.cpu with cpufreq and/or acpi_perf loaded. This is all I have: dev.cpu.0.%desc: ACPI CPU (2 Cx states) 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 The above is the same for the following conditions: o cpufreq AND acpi_perf NOT loaded o cpufreq (without acpi_perf) loaded o acpi_perf (without cpufreq) loaded o cpufreq AND acpi_perf loaded The acpi_ppc module does continue to work for me, however, yielding the following additional OIDs from hw.acpi: ----------8<-------------- # sysctl hw.acpi.cpu hw.acpi.cpu.cx_supported: C1/0 C2/80 hw.acpi.cpu.cx_lowest: C2 hw.acpi.cpu.cx_usage: 2.36% 97.63% # kldload acpi_ppc # sysctl hw.acpi.cpu hw.acpi.cpu.cx_supported: C1/0 C2/80 hw.acpi.cpu.cx_lowest: C2 hw.acpi.cpu.cx_usage: 2.32% 97.67% hw.acpi.cpu.px_control: -1 hw.acpi.cpu.px_highest: 0 hw.acpi.cpu.px_lowest: 2 hw.acpi.cpu.px_current: 2 hw.acpi.cpu.px_supported: 2200 1800 800 hw.acpi.cpu.px_usage: 3.33% 3.33% 93.33% ----------8<-------------- All the stuff you would normally ask for can be found here: http://michael.gargantuan.com/sager_4750v/index.htm#Utility_Command_Output Also, I had to build the cpufreq and acpi_perf modules manually, as they weren't built automatically. Maybe they aren't "connected" to the build for AMD64?
