![i9-11900k 视频工作正常,CPU 调速器异常,Z590 主板 Ubuntu 20.04 oem 内核](https://linux22.com/image/936873/i9-11900k%20%E8%A7%86%E9%A2%91%E5%B7%A5%E4%BD%9C%E6%AD%A3%E5%B8%B8%EF%BC%8CCPU%20%E8%B0%83%E9%80%9F%E5%99%A8%E5%BC%82%E5%B8%B8%EF%BC%8CZ590%20%E4%B8%BB%E6%9D%BF%20Ubuntu%2020.04%20oem%20%E5%86%85%E6%A0%B8.png)
在此处的帮助下解决了我的图形问题后:新华硕 Z590 主板上显示空白(无信号)
并在这里帮助别人:使用 Rocket Lake 的 Ubuntu 21.04 中未声明的显示
我的 11900k“powersave”调节器 (cpupower) 只允许最高 4.7ghz,这有点问题。如果我使用 cpupower-gui 手动将其更改为“性能”,我可以使用 s-tui 在重度 AVX 上将时钟频率提高到 5.3ghz 和 5.1,就像我的主板设置的那样。
有没有办法“修复”内置于此 OEM 内核中的省电调节器,以允许在省电模式下达到最大速度?因为在性能模式下,它不断加速到 5ghz 以上,并且运行温度稍高。我到处搜索微代码,但无济于事。我对修改内核一无所知。
旁注:我将在单独的线程中询问:iperf 显示我的 2.5gb NIC 仅以千兆速度运行,针对已知的 2.5gb 连接进行测试(可与其他 PC 全速运行)。
看起来我们需要一些来自英特尔的实际 Linux 驱动程序,这是怎么回事呢?
更新以添加 inxi 输出:
CPU: 8-Core 11th Gen Intel Core i9-11900K (-MT MCP-)
speed/min/max: 3726/800/5300 MHz Kernel: 5.10.0-1023-oem x86_64 Up: 1h

Shell: bash 5.0.17 inxi: 3.0.38
^^^ 存储输出也很奇怪,只显示我的硬件 raid 阵列,而不是我的 3 个 NVMe 驱动器
更新:我安装了内核 5.12。起初我以为我无法启动它,直到我将其中一根显示器电缆移到我的独立 GPU 上。它在板载显卡上启动,然后只显示一个闪烁的光标,GPU 连接的显示器接管了单显示器桌面。CPU 调速器速度仍存在同样的问题,仍然没有 2.5G 以太网。
更新 2:根据 Doug Smythies 的要求,在 Grub 更改之前:

s-tui 没有变化。我对 systemctl 做了一些操作,强制它启动到性能模式。我记得是按需禁用的。性能模式报告 5000mhz,根据我的 BIOS 设置,对于重度 AVX 来说是正确的,省电模式仍然为 4700mhz

所以它闲置时耗电就超过 4 瓦。这不是什么大问题,但我还是想修好它。
另外,我的 turbo_pct 应该大约为 51 才是正确的。似乎找不到可以更改它的方法。也许内核将我的 CPU 视为非 K 版本?例如 11900 而不是 11900k,但当我检查 hwinfo 之类的东西时,它显示 11900k

答案1
请注意,使用性能调节器运行通常不会导致大量额外的处理器封装散热。是的,CPU 以更高的频率运行,并且在涡轮区域使用的能量是高度非线性的,但它们也能更快地完成工作,因此在深度空闲状态下花费更多时间,几乎不消耗任何能量。例如,使用 i5-10600K:

观察空闲系统的成本约为0.1瓦。
对于不是那么空闲(但仍然相当空闲)的情况,类似的中断/采样周期:

所以,成本大约为 13 瓦,相当高。

大约4.5瓦。
編輯:现在,您的 intel_pstate 参数很有趣,但我对数字定义的理解不正确:
来自文档:
Sysfs will show :
max_perf_pct:100, which corresponds to 1 core ratio
min_perf_pct:24, max_efficiency_ratio / max 1 Core ratio
no_turbo:0, turbo is not disabled
num_pstates:26 = (max 1 Core ratio - Max Efficiency Ratio + 1)
turbo_pct:39 = (max 1 core ratio - max non turbo ratio) / num_pstates
从代码来看:
static ssize_t show_turbo_pct(struct kobject *kobj,
struct kobj_attribute *attr, char *buf)
{
struct cpudata *cpu;
int total, no_turbo, turbo_pct;
uint32_t turbo_fp;
mutex_lock(&intel_pstate_driver_lock);
if (!intel_pstate_driver) {
mutex_unlock(&intel_pstate_driver_lock);
return -EAGAIN;
}
cpu = all_cpu_data[0];
total = cpu->pstate.turbo_pstate - cpu->pstate.min_pstate + 1;
no_turbo = cpu->pstate.max_pstate - cpu->pstate.min_pstate + 1;
turbo_fp = div_fp(no_turbo, total);
turbo_pct = 100 - fp_toint(mul_fp(turbo_fp, int_tofp(100)));
mutex_unlock(&intel_pstate_driver_lock);
return sprintf(buf, "%u\n", turbo_pct);
}
因此,对于您的处理器,规格为 3.5 GHz 基本频率、0.8 GHz 最小频率、5.3 GHz 最大频率。
对于您的情况,(53 - 35) / 46 = 39%。足够接近,并且按照精确的代码方式执行,结果为 40%。
编辑2:请参见这文章。最相关的摘录:
这意味着,如果所有 8 个内核都已加载,TB2 意味着它将以 4.7 GHz 运行。如果有功率预算和热预算,它将尝试 4.8 GHz。如果有更多的功率预算和热预算可用,它将转到 4.9 GHz,然后是 5.0 GHz,然后是 5.1 GHz。只要有足够的预算可供使用,频率就会浮动,并会根据需要增加/减少。这很重要,因为不同的指令会导致不同的功耗等。
答案2
原来这是 CPU 频率的 BIOS 问题。我之前运行的是更新版本 (0704),已更新至 2021 年 4 月 28 日发布的 0707,现在我的 CPU 可以在满负荷的情况下全速运行。
以下是华硕最新 BIOS 的链接:https://rog.asus.com/us/motherboards/rog-strix/rog-strix-z590-e-gaming-wifi-model/helpdesk_bios
现在我将检查我的网络,看看那里是否有任何变化。如果没有添加显卡,仍然无法在主线内核或普通内核上启动 GUI。
使用 iperf 检查网络。仍然以 1gb 而不是 2.5 运行
