N00 内核补丁
这个小主机需要打两个补丁，一个是关于显卡 sriov 的补丁,另外一个是关于风扇的补丁 IT87.
- 显卡补丁
i915-sriov-dkms这个在上篇已经介绍了。 - 风扇
IT87补丁
项目都在github，大家搜索可以下到，为了比较懒的小伙伴，我计划把修改好的内核上传到github，大家可以直接下载到，再做个脚本文件，全自动化也不是不可以，一键脚本？
IT87 补丁
这篇主要介绍风扇驱动的 it87 补丁, 下载关键字：a1wong/it87
- 下载补丁
- 安装补丁
Building & Installing
---------------------
* make clean
* make
* sudo make install
Using DKMS
----------
To install:
* sudo make dkms
To remove:
* sudo make dkms_clean
搞完了以后还需要添加一个驱动启用文件
编辑 /etc/modules-load.d/it87.conf
添加 it87
大家可以用我提供的现成的命令执行：
echo "it87" > /etc/modules-load.d/it87.conf
还是常规，更新initramfs
Update-initramfs -u -k all
重启
reboot
检查是否成功
检查驱动是否加载
lsmod | grep it87
需要先安装 lm-sensors
- 安装
apt install lm-sensor
- 传感器检测
sensors-detect --auto
- 如果内核补丁打好了，就会如下显示：
注意会出现 fan也就是风扇.
fan2: 514 RPM (min = 10 RPM)
如果没打补丁，会检测不到风扇。
