我有一个令人沮丧的谜团,我希望有人能指出我正确的方向。
s-tui我主要使用和 来评估手动测试中的频率和负载stress。lsmod | grep intel

driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us
hardware limits: 400 MHz - 2.30 GHz
available frequency steps: 2.30 GHz, 2.30 GHz, 2.20 GHz, 2.00 GHz, 1.80 GHz, 1.70 GHz, 1.60 GHz, 1.50 GHz, 1.30 GHz, 1.20 GHz, 1.10 GHz, 900 MHz, 800 MHz, 700 MHz, 500 MHz, 400 MHz
available cpufreq governors: conservative ondemand userspace powersave performance schedutil
current policy: frequency should be within 400 MHz and 1.80 GHz.
The governor "ondemand" may decide which speed to use
within this range.

intel_pstate=disbale通过添加到 grub来启用/禁用 intel pstate 驱动程序。但我认为我的系统甚至没有使用它。cpupower frequency-set --governor使用和手动设置最小/最大频率和调速器cpufreq-set -r --min=0.8GHz --max=2.3GHzsudo apt install acpi-support acpid acpi。我也尝试过删除这些。freq-info 声称我正在使用 acpi,即使我删除了这些,所以我可能没有任何效果。cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq和报告的最小/最大频率cpupower frequency-info似乎不正确。s-tui在这种糟糕的状态出现之前,我可以看到频率高达 4.2GHz 。s-tui并开始压力测试,我实际上会看到我想要的结果,所有核心都会上升到 3.5ghz -4.2ghz。在某些时候,他们只会达到 0.8GHz - 1.1GHz。实际上,它们在压力测试前闲置时会变得更高,然后锁定在较低频率。cpupower frequency-info. 负载下CPU频率不会上升。任何指示将不胜感激。
我放弃了,买了一台新笔记本电脑。暂时不用thinkpad了。

我遇到了同样的问题,CPU 在启动后不久就停止运行。我尝试了许多不同的调整和实用程序,直到 OEM 最终更换了我笔记本电脑上的主板。我很确定这是由错误的热传感器报告错误的温度造成的,导致 CPU 节流。
