intel_pstate 드라이버에 몇 가지 문제가 있습니다.
질문 1) 터보를 비활성화할 수 없습니다. 다음을 통해 BIOS에서 비활성화됩니다.
root@think:~# cat /sys/devices/system/cpu/intel_pstate/no_turbo
1
문제 2) 최대 주파수를 제한할 수 없습니다. "max_perf_pct"는 33으로 설정되고, "min_perf_pct"는 동일합니다. CPU는 모든 설정을 완전히 무시합니다.
Socket [0] - [physical cores=2, logical cores=4, max online cores ever=2]
TURBO DISABLED on 2 Cores, Hyper Threading ON
Max Frequency without considering Turbo 2893.00 MHz (99.76 x [29])
Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is 36x/34x/34x/34x
Real Current Frequency 3227.37 MHz [99.76 x 32.35] (Max of below)
Core [core-id] :Actual Freq (Mult.) C0% Halt(C1)% C3 % C6 %
Core 1 [0]: 3227.37 (32.35x) 44.4 39.2 0 1
Core 2 [2]: 3189.89 (31.98x) 43.3 44.3 1 1
"2코어에서 TURBO 비활성화"...그렇지 않은 것 같은데요?
analyzing CPU 0:
driver: intel_pstate
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 0.97 ms.
hardware limits: 1.20 GHz - 3.60 GHz
available cpufreq governors: performance, powersave
current policy: frequency should be within 1.20 GHz and 3.60 GHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency is 1.20 GHz (asserted by call to hardware).
