Linux 有問必答: 如何在紅帽系linux中編譯Ixgbe驅動

第一步: 安裝依賴

首先，安裝必要的開發環境和安裝匹配的內核頭文件

$ sudo yum install gcc make
$ sudo yum install kernel-devel

第二步: 編譯Ixgbe

從官方頁面下載最新Ixgbe源碼

$ wget http://downloads.sourceforge.net/project/e1000/ixgbe%20stable/3.23.2/ixgbe-3.23.2.tar.gz 

請檢查支持的內核版本。例如，Ixgbe3.23.2版本支持Linux內核版本2.6.18到3.18.1。

提取壓縮包並編譯：

$ tar -xvf ixgbe-3.23.2.tar.gz
$ cd ixgbe-3.23.2/src
$ make 

如果成功，可以在當前目錄找到編譯完成的驅動（ixgbe.ko）。

可以運行這個命令來查看編譯信息：

$ modinfo ./ixgbe.ko 

將會輸出一個Ixgbe驅動的可用參數列表

第三步: 載入 Ixgbe 驅動

這步準備載入已經編譯好的驅動。

如果系統已經載入了Ixgbe驅動，首先需要卸載掉老版本。否則，新版本不能載入。

$ sudo rmmod ixgbe.ko

然後插入編譯完成的驅動到內核中：

$ sudo insmod ./ixgbe.ko

同時，你可以設置啟動參數

$ sudo insmod ./ixgbe.ko FdirPballoc=3 RSS=16

驗證驅動是否載入成功，使用dmesg命令，查看其輸出

$ dmesg

第四步: 安裝Ixgbe驅動

當確認驅動已經載入後，就可以安裝驅動到系統中了

$ sudo make install

ixgbe.ko將會安裝在下列目錄

/lib/modules/<kernel-version>/kernel/drivers/net/ixgbe

此時，編譯好的驅動將在啟動時自動載入，也可以通過運行命令載入它：

$ sudo modprobe ixgbe
