Linux users want two things for their hardware: drivers; and easy access to those drivers. The first is finally happening; and now, thanks to a Dell Linux project called DKMS (Dynamic Kernel Module Support), the other is on its way.
Dell and Linux distributors have been working on DKMS for about five years now. Its purpose is to create a framework where kernel-dependent module source can reside, so that it is very easy to rebuild modules. In turn, this enables Linux distributors and driver developers to create driver drops without having to wait for new kernel releases. For users, all this makes it easier to get up-to-the-minute drivers without hand compiling device drivers.
According to Dell, this separate framework for delivering drivers will remove kernel releases as a blocking mechanism for distributing code. The net effect, Dell hopes, is to speed up driver development by enabling quicker testing cycles. This also means that better tested code can be pushed back into the kernel at a more rapid pace. It's also nice for developers and maintainers, as DKMS only requires a source tarball in conjunction with a small configuration file in order to function correctly.
What makes this project more interesting for all Linux users is that another project related to the DKMS project, mkrpm (make RPM), now adds automatic lines with modalias information. Modalias, for those of you who aren't Linux device driver developers, is a data structure that's used to hold the information that a device presents to the kernel.
