Dynamic Kernel Module Support (DKMS)

is a framework used to generate Linux kernel modules whose sources do not generally reside in the Linux kernel source tree. DKMS enables kernel device drivers to be automatically rebuilt when a new kernel is installed.

An essential feature of DKMS is that it automatically recompiles 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 one to install 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.

Occasionally, my system gets into a state where some kernels are missing a module or two, because DKMS somehow forgot to compile those modules for that kernel. Rather than spend time diagnosing the problem, it would be nice if there was a single…
