This article introduces the knowledge of "how to compile and install ixgbe drivers in Linux". Many people will encounter this dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Intel's 10g network cards (for example, 82598, 82599, x540) are supported by ixgbe drivers. Modern linux distributions already come with an ixgbe driver that can be used as a loadable module. However, there are situations where you want to compile and install ixgbe drivers on your machine, for example, when you want to experience the latest features of ixbge drivers. Similarly, one of the problems with the default ixgbe driver in the kernel is that it does not allow you to customize the parameters of the driver. If you want a fully customized ixgbe driver (such as rss, multiple queues, interrupt thresholds, etc.), you need to manually compile the ixgbe driver from the source code.

Step 1: installation premise

Before installation, you need to install matching kernel header files and development kits.

$sudo apt-get install linux-headers-$ (uname-r) $sudo apt-get install gcc make

Step 2: compile the ixgbe driver

Download the source code from the latest ixgbe driver.

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

Compile the ixgbe driver as follows.

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

Step 3: check the ixgbe driver

After compiling, you will see that the ixgbe.ko is created in the ixgbe-3.23.2/src directory. This is the ixgbe driver that will be loaded into the kernel.

Check the information of the kernel module with the modinfo command. Note that you need to specify the absolute path to the module file (such as. / ixgbe.ko or / home/xmodulo/ixgbe/ixgbe-3.23.2/src/ixgbe.ko). The version of the ixgbe kernel is displayed in the output.

Step 4: test the ixgbe driver

Before testing a new module, you need to remove it if you already have an old version of the ixgbe module in your kernel.

$sudo rmmod ixgbe

Then use the insmod command to insert the newly compiled ixgbe module. Be sure to specify the absolute path of a module.

$sudo insmod. / ixgbe.ko

If the above command runs successfully, no information is displayed.

If you want, you can try to add additional parameters. For example, set the number of queues for rss to 16:

$sudo insmod. / ixgbe.ko rss=16

Check / var/log/kern.log to see if the ixgbe driver was activated successfully. View "intel (r) 10 gigabit pci express network driver" in the log. The version information of ixgbe should be the same as the previous modinfo display.

Sep 18 14:48:52 spongebob kernel: [684717.906254] intel (r) 10 gigabit pci express network driver-version 3.22.3

Step 5: install the ixgbe driver

Once you have verified that the new ixgbe driver can be loaded successfully, the final step is to install the driver on your system.

$sudo make install

Ixgbe.ko will be installed under / lib/modules//kernel/drivers/net/ethernet/intel/ixgbe.

From this step, you can load the ixgbe driver with the following modprobe command. Note that you no longer have to specify an absolute path.

$sudo modprobe ixgbe

If you want to load the ixgbe driver at startup, you can add "ixgbe" at the end of / etc/modules.
