Releases 12 Code cleanup and refactoring Latest. You should see that the ixgbe driver of the same version has automatically been built for a new kernel 3. Note that if you had upgraded to a new kernel without installing matching kernel headers, DKMS wouldn't have been triggered, and the driver wouldn't have been re-built from its source.

Instead, a stock kernel driver if available that came with the new kernel would have been used. For example, the following is the result of upgrading to a new kernel without matching kernel headers, where you can see that the new kernel loaded a stock ixgbe driver whose version is a little outdated.

You can always re-build the custom driver at any time by triggering DKMS manually as follows. Be sure to install matching kernel headers first. Granted, DKMS may not always be preferred especially in production Linux environments where development packages and build tools are typically not allowed. But for development environments or personal desktop, if you have any custom-built kernel module, DKMS makes your life easy by keeping the module updated against new kernels.

How to build a kernel module with DKMS on Linux Last updated on November 25, by Dan Nanni Suppose you wanted to install a device driver for a new graphics card, a WiFi dongle, or a network interface card that you purchased, and for whatever reason e.

Before upgrading the kernel, check the version of ixgbe driver and the kernel. Though the rebuild of the DKMS modules is usually seamless during a kernel upgrade, it may still happen that the rebuild fails. You should pay extra attention to the pacman output. To deal with changes in the kernel, fix bugs, or add necessary features consider upgrading the DKMS package before rebooting. If the package dkms is removed the information regarding previous module build files is lost.

See DKMS package guidelines. In case you have got any kernel modules installed via DKMS that are used in initial ramdisk , e.
