PVE 8安装 ReakTEK RTL8125B 2.5G网卡驱动

本文同步发表在我的个人博客https://evine.win。

前言

近期在PVE中发现,只要连接数一多,PVE会有两个单核的使用率明显比其他核超过一大截。经过查询资料发现,这是因为我的 RealTEK RTL8125 2.5GB 网卡默认加载的驱动是r8169,它并没有开启网卡多队列等特性。导致一个网卡的软中断只能使用固定的一个核心开接收和发送数据。

查看网卡加载的是什么驱动:

## 看看网卡的pci编号
$ lspci | grep RTL8125 
22:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
2a:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)

## 看看网卡加载的驱动
$ lspci -s 22:00.0 -k # 22:00.0这块网卡
22:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
        Subsystem: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller
        Kernel driver in use: r8169
        Kernel modules: r8169

$ lspci -s 2a:00.0 -k # 2a:00.0这块网卡
2a:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
        Subsystem: Micro-Star International Co., Ltd. [MSI] RTL8125 2.5GbE Controller
        Kernel driver in use: r8169
        Kernel modules: r8169

查看网卡软中断数量:

$ cat /proc/interrupts | grep -P 'eth|CPU0'  # 我的网卡名叫eth0、eth1
            CPU0       CPU1       CPU2       CPU3       CPU4       CPU5       CPU6       CPU7       CPU8       CPU9       CPU10      CPU11      CPU12      CPU13      CPU14      CPU15      
  51:          0          0          0          0          0          0          0          0          0  631894756          0          0          0          0          0          0  IR-PCI-MSIX-0000:22:00.0    eth0
  59:          0          0          0          0          0          0          0          0          0          0          0  932824696          0          0          0          0  IR-PCI-MSIX-0000:2a:00.0    eth1

也可以用这个命令看看软件中断(%soft)是不是大量集中在某个核心上。

$ mpstat -P ALL 1 5

连接数多的时候,甚至这两个核心的使用率能达到80%,而其他核心才不到20%。所以还是有必要将该网卡驱动从Linux默认的r8169切换到官方驱动上。

使用官方驱动

已经有大佬把官方驱动打包成了dkms deb包:realtek-r8125-dkms,不过该deb包并没有打开网卡多队列,所以我FORK了一份,启用TX多队列及RSS,禁用ASPM,发布在:https://github.com/devome/realtek-r8125-dkms ,直接使用即可。先下载Release中最新的deb文件,再按下方流程安装即可:

## 更新内核、安装依赖
$ apt update
$ apt upgrade
$ apt install -y dkms pve-headers #pve 8.0.4+建议将pve-headers替换为proxmox-default-headers

## 安装headers
$ headers=$(dpkg -l | awk '/^ii.+kernel-[0-9]+\.[0-9]+\.[0-9]/{gsub(/-signed/, ""); gsub(/kernel/, "headers"); print $2}' | tr "\n" " ")
$ eval apt install -y $headers

## 安装刚刚下载好的deb包,此命令只会为当前系统所使用的内核以及刚刚安装的最新内核(也可能当前所使用的内核就是最新内核)安装驱动
$ dpkg -i realtek-r8125-dkms_*.deb  # 如通配符会匹配多个时亦可指定具体的文件名

## 如果想为那些既不是系统当前所使用的内核,也不是刚刚安装的最新内核安装驱动,需要手动指定安装
## 看看哪些内核安装好了驱动
$ dkms status
## 列出全部内核版本kernel_version,找出那些还没有安装驱动的内核
$ dpkg -l | awk '/^ii.+kernel-[0-9]+\.[0-9]+\.[0-9]/{gsub(/proxmox-kernel-|pve-kernel-|-signed/, ""); print $2}'
## 手动指定驱动版本(在deb文件名中有体现)和内核版本(从上一句命令的输出中),zsh按tab可自动补全,比如:dkms install realtek-r8125/9.011.01 -k 6.2.16-5-pve
$ dkms install realtek-r8125/ -k 

## 卸载不再需要的headers
$ eval apt-mark auto $headers
$ apt autopurge

## 禁用r8169驱动
$ echo "blacklist r8169" >> /etc/modprobe.d/dkms.conf

## 重启
$ update-grub
$ update-initramfs -u -k all
$ reboot

## 再次查看网卡加载的驱动,现在加载的是r8125了
$ lspci -s 22:00.0 -k
22:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
        Subsystem: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller
        Kernel driver in use: r8125
        Kernel modules: r8169, r8125

每个网卡都用到了多个核心来处理软中断,效果不错。根据这个帖子的说法,9.011.01版本驱动是1个rx队列和2个tx队列。

再看看cpu各核心的使用率是否相对均衡:
