我安装了 Ubuntu 20.04，并且具有以下 CPU：
grep -E '^model name|^cpu MHz' /proc/cpuinfo
model name : Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz
cpu MHz : 3000.025

cpu MHz : 2989.114
model name : Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz
cpu MHz : 3001.278
我使用以下命令来设置调速器和频率范围：
sudo cpupower frequency-set --governor performance --min 2600000 --max 3000000
并使用以下命令来验证：
cpupower frequency-info
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: Cannot determine or is not supported.
hardware limits: 400 MHz - 4.00 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 2.60 GHz and 3.00 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 3.00 GHz (asserted by call to kernel)
boost state support:
Supported: yes
Active: yes
电流频率在指定范围内，在空载条件下是正确的。
然而，在我启动加载 CPU 的程序（gmic）后，当前频率降至指定范围以下：
cpupower frequency-info
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: Cannot determine or is not supported.
hardware limits: 400 MHz - 4.00 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 2.60 GHz and 3.00 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 1.80 GHz (asserted by call to kernel)
boost state support:
Supported: yes
Active: yes
在 Windows 下，我运行相同的应用程序，并实现了更高的性能。在无负载条件下，频率约为 1GHz，而在负载下，频率跳升至 2.6GHz。因此，我认为这不是硬件或 BIOS 相关的问题。
我重启了 Ubuntu 以放弃我的 CPU 频率更改（因此它们再次恢复为默认值）。我将使用以下命令监控 CPU 频率和其他重要信息涡轮增压器公用事业。
以下是涡轮增压器输出：

因此，Ubuntu 似乎正在限制 CPU 功耗。由于不可能保持在高负载下并保持在指定的频率范围内（当功耗降低时），因此频率会下降以满足功率限制。
现在我再次重新启动 Ubuntu，因此 CPU 频率恢复到默认值。
我确实正在运行thermald：

我的笔记本电脑一直处于插入状态，因此不会出现与电池相关的电源限制问题。
你知道如何在 Ubuntu 上关闭 CPU 功率限制吗？这样 CPU 将消耗保持高频率所需的最大功率。任何评论都将受到赞赏。谢谢。

读者们：请大家耐心等待，最终问题和答案有望缩减为一些简洁的内容。
在提供的所有信息中，这是最相关的：

表明处理器目前由于处理器封装功率限制 #1 而受到限制，但与此同时处理器还远未达到封装功率限制 #1，至少如果我们相信 turbostat 告诉我们的话。
手动解码 MSR 0x64F 可得出，除其他外，位 10 被设置。来自 64-ia-32-architectures-software-developer-manual-325462：
封装/平台级功率限制 PL1 状态（R0）设置时，由于封装/平台级功率限制 PL1，频率会降低到操作系统要求以下。
其余位均为锁存日志位，目前不相关。
RAPL_POWER_UNIT MSR（0x606）给出 0x000a0e03，它正确解码为每比特 0.125 瓦。
PKG_POWER_LIMIT MSR (0x610) 给出 0x42016000dc8090。让我们手动解码功率限制 1 部分。位 14:0 定义限制，或十进制的 90h 或 144。乘以 .125 = 18 瓦，正如预期的那样。位 15 为 1，因此已启用。
因此，似乎出现了问题，处理器的运行似乎没有正常进行。
这可能与异常高的处理器封装限制 #2 有关吗？通常，它会被设置为功率限制 #1 的 1.25 倍左右。如此高的值可能会产生问题。
编辑 1：返回 MSR 0x64F，其他锁存位指示温度、PROCHOT（始终不好）和“其他”情况之前已经发生过。我自己会将功率限制 2 从 44 瓦调低到大约 22 或 23 瓦。还建议从 CPU 频率的低端开始，慢慢地观察这一点。例如，设置一个非常低的 CPU 最大频率：
echo 10 | sudo tee /sys/devices/system/cpu/intel_pstate/max_perf_pct
然后施加重负载，同时在两个终端窗口中同时使用 turbostat 和 MSR 0x64f 进行观察。逐渐增加 CPU 频率：
echo 15 | sudo tee /sys/devices/system/cpu/intel_pstate/max_perf_pct
echo 20 | sudo tee /sys/devices/system/cpu/intel_pstate/max_perf_pct
echo 25 | sudo tee /sys/devices/system/cpu/intel_pstate/max_perf_pct
...
直至其节流。
编辑 2：时钟调制可能与此有关，如果是的话，可能是来自 BIOS，也可能是由于功率限制 #2 的设置过高。要知道这一点，可以在奇数节流事件期间读取 MSR 0x19A。执行sudo rdmsr -a 0x19a。示例：

... apply load and start turbstat ...
root@s19:/home/doug# wrmsr -a 0x19a 0 <<< disable CM
预期问题：那么为什么直到负载移除后它才会自行纠正。
答案：由于恶劣的条件导致首先需要时钟调制，因此直到情况真正平静和凉爽时才会将其移除。在某些计算机上，它永远不会重置。

Windows 上的 CPU 微码版本：
reg query HKLM\HARDWARE\DESCRIPTION\System\CentralProcessor\0 | find "Update Revision"
Update Revision REG_BINARY 00000000B4000000
Previous Update Revision REG_BINARY 0000000084000000
更新修订是当前的微码版本。 上一次更新修订是 BIOS 中硬编码的微码版本。
英特尔处理器识别实用程序在 Windows 上显示CPU 版本确实是B4。因此实际上 Windows 运行的是旧版本的微码。
然而，在将 Ubuntu 上的微码从E0到B4. 因此有缺陷的微代码在这里不是问题。
我删除了intel_powerclamp模块（以防万一）：
sudo rmmod intel_powerclamp
在顶部我看到的输出空闲注入每个 CPU 核心的进程：
idle_inject/0
idle_inject/1
idle_inject/2
idle_inject/3
这是空闲注入框架（CONFIG_IDLE_INJECT）这是在 Linux 内核 4.19 中引入的
其目的是对系统进行功率钳位，所以可能会导致这样的功率下降？
答案4
Ubuntu 20.04 更新后一切似乎运行正常。
sudo stress --cpu 8
系统监视器显示 CPU 负载突然跳升至 100%，并且一直保持在 100%，直到我终止压力应用程序。
