i9-11900k 视频工作，cpu 调速器 goofy，Z590 主板 Ubuntu 20.04 oem 内核

772

在此处的帮助下解决了我的图形问题后：新华硕 Z590 主板上的空白（无信号）显示

并帮助其他人：UnclaImed display in ubuntu 21.04 with Rocket Lake

我的 11900k “powersave” governor (cpupower) 有问题，只允许最大 4.7ghz。如果我使用 cpupower-gui 手动将其更改为“性能”，我可以使用 s-tui 在重型 AVX 上时钟高达 5.3ghz 和 5.1，就像我的主板设置的那样。

有没有办法“修复”内置在这个 oem 内核中的省电调速器，以在省电模式下实现最大速度？因为在性能模式下，它不断地加速到超过 5ghz 并且运行得更热。我到处搜索微码无济于事。我对修改内核一无所知。

旁注：我将在单独的线程中提问：iperf 显示我的 2.5gb NIC 仅以千兆位速度运行，测试已知 2.5gb 连接（与其他 PC 全速工作）。

似乎我们需要一些来自英特尔的实际 linux 驱动程序，有什么用？

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     
05m 
Mem: 1485.8/64079.5 MiB (2.3%) Storage: 11.94 TiB (12.7% used) Procs: 
369 
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。最初我以为我无法启动它，直到我将一根显示器电缆移到我的独立 GPU 上。它在板载图形上启动，然后只显示一个闪烁的光标，然后连接 gpu 的监视器接管单个监视器桌面。CPU调速器速度仍然存在同样的问题，并且仍然没有2.5G以太网。

s-tui 没有变化。我用 systemctl 做了一些事情来强制它启动到性能模式。我记得禁用了按需。性能模式报告 5000mhz，根据我的重 AVX BIOS 设置正确，节电仍为 4700mhz

所以我在闲置时花费了 4 瓦。没什么大不了的，但我仍然想修复它。

此外，我的 turbo_pct 应该大约为 51 才正确。似乎不是我能找到的改变它的方法。也许内核将我的 CPU 视为非 K 版本？像 11900 而不是 11900k 但是当我检查 hwinfo 之类的东西时它显示 11900k

请注意，使用性能调控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 turbo 区域使用的能量是高度非线性的，但它们也可以更快地完成工作，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。

对于不那么空闲（但仍然相当空闲），类似的中断/采样周期：

大约 4.5 瓦。

编辑：现在，您的 intel_pstate 参数很有趣，但我对数字定义的理解不正确：

从文档中：

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：

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，规格是 3.5 GHz 基本频率，最低 0.8 GHz，最高 5.3 GHz。

(53 - 35) / 46 = 39% 适合您的情况。足够接近，并以确切的代码方式执行，给出 40%。

编辑2：请参阅这篇文章。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。如果有更多可用的功率预算和热预算，它将达到 4.9 GHz，然后是 5.0 GHz，然后是 5.1 GHz。只要有足够的预算可以使用，频率就会浮动，并且会根据需要增加/减少。这很重要，因为不同的指令会导致不同的功耗等。

原来这是CPU频率的BIOS问题。我正在运行更新版本 (0704)，更新到 2021 年 4 月 28 日发布的 0707，现在我的 CPU 将在负载下全速运行。

这是华硕最新 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。在没有添加显卡的情况下，仍然无法在主线内核或库存内核上启动 GUI。

使用 iperf 检查网络。仍然以 1GB 而不是 2.5 运行
