Here's one box:
CPU: Intel(R) Core(TM)2 Duo CPU E8500 @ 3.16GHz
cpu0: <ACPI CPU> on acpi0
est0: <Enhanced SpeedStep Frequency Control> on cpu0
est: CPU supports Enhanced Speedstep, but is not recognized.
est: cpu_vendor GenuineIntel, msr 61a49200600091a
device_attach: est0 attach returned 6
p4tcc0: <CPU Frequency Thermal Control> on cpu0
Here's another one:
CPU: Intel(R) Xeon(R) CPU E5410 @ 2.33GHz
cpu0: <ACPI CPU> on acpi0
est0: <Enhanced SpeedStep Frequency Control> on cpu0
est: CPU supports Enhanced Speedstep, but is not recognized.
est: cpu_vendor GenuineIntel, msr 720072006000720
device_attach: est0 attach returned 6
p4tcc0: <CPU Frequency Thermal Control> on cpu0
SYSCTLs On the first one:
dev.cpu.0.freq: 2786
dev.cpu.0.freq_levels: 2786/-1 2437/-1 2089/-1 1741/-1 1393/-1 1044/-1
696/-1 348/-1
Attempting to change dev.cpu.0.freq has no effect and says:
sysctl: dev.cpu.0.freq: Invalid argument
