Cpuinfo_max_freq 和scaling_max_freq
WebAug 2, 2008 · Re: CPU Scaling. It's only 2-3 Watts difference and that has to be mostly due to the reduced VCore needed at the lower frequency as power is proportional to frequency but proportional to the square of voltage, so the voltage has a greater impact. Your numbers would likely be even lower as you have 2 cores verses my 4. WebWhen initialized, intel_pstate sets the maximum frequency of the CPU depending on the availability of the turbo, as indicated by MSR_IA32_MISC_ENABLE_TURBO_DISABLE. On some systems, the BIOS changes the value of MSR_IA32_MISC_ENABLE_TURBO_DISABLE at runtime (e.g., when the power source …
