Hello list, I've been able to get some more info. cc'd to freebsd-performance@ which on 2nd thoughts might have been the better place to ask... [ powerd: no cpufreq(4) support -- aborting: No such file or directory ] Right, I've found that what this chip has is AMD Turbo Core. So really my question is, can powerd make use of Turbo Core? Here's some sysctl output: # sysctl -a | grep dev.cpu dev.cpu.3.cx_usage: 100.00% 0.00% last 79194us dev.cpu.3.cx_lowest: C1 dev.cpu.3.cx_supported: C1/1/0 C2/2/100 dev.cpu.3.temperature: 47.6C dev.cpu.3.%parent: acpi0 dev.cpu.3.%pnpinfo: _HID=none _UID=0 dev.cpu.3.%location: handle=\_PR_.C003 dev.cpu.3.%driver: cpu dev.cpu.3.%desc: ACPI CPU dev.cpu.2.cx_usage: 100.00% 0.00% last 45553us dev.cpu.2.cx_lowest: C1 dev.cpu.2.cx_supported: C1/1/0 C2/2/100 dev.cpu.2.temperature: 47.6C dev.cpu.2.%parent: acpi0 dev.cpu.2.%pnpinfo: _HID=none _UID=0 dev.cpu.2.%location: handle=\_PR_.C002 dev.cpu.2.%driver: cpu dev.cpu.2.%desc: ACPI CPU dev.cpu.1.cx_usage: 100.00% 0.00% last 40us dev.cpu.1.cx_lowest: C1 dev.cpu.1.cx_supported: C1/1/0 C2/2/100 dev.cpu.1.temperature: 47.6C dev.cpu.1.%parent: acpi0 dev.cpu.1.%pnpinfo: _HID=none _UID=0 dev.cpu.1.%location: handle=\_PR_.C001 dev.cpu.1.%driver: cpu dev.cpu.1.%desc: ACPI CPU dev.cpu.0.cx_usage: 100.00% 0.00% last 17478us dev.cpu.0.cx_lowest: C1 dev.cpu.0.cx_supported: C1/1/0 C2/2/100 dev.cpu.0.temperature: 47.6C dev.cpu.0.%parent: acpi0 dev.cpu.0.%pnpinfo: _HID=none _UID=0 dev.cpu.0.%location: handle=\_PR_.C000 dev.cpu.0.%driver: cpu dev.cpu.0.%desc: ACPI CPU dev.cpu.%parent: thanks, -- John
