s all DKMS modules if a new kernel version is installed. This allows drivers and devices outside of the
mainline kernel to continue working after a Linux kernel upgrade.
Another benefit of DKMS is that it allows the installation of a new driver on an existing system, running an arbitrary kernel version, without any need for manual compilation or precompiled packages provided by the vendor.
