[[meta title="New Driver Glue Code"]]
Although a driver framework in userspace would be desirable, presently the Hurd
uses kernel drivers in the microkernel,
[[GNU_Mach|microkernel/mach/gnumach]]. (And changing this would be far beyond a
GSoC project...)
The problem is that the drivers in GNU Mach are presently old Linux drivers
(mostly from 2.0.x) accessed through a glue code layer. This is not an ideal
solution, but works quite OK, except that the drivers are very old. The goal of
this project is to redo the glue code, so we can use drivers from current Linux
versions, or from one of the free BSD variants.
Using [ddekit](http://demo.tudos.org/dsweeper_tutorial.html) instead of our
own glue code can be explored as a possible alternative approach.
This is a doable, but pretty involved project. Experience with driver
programming under Linux (or BSD) is a must. (No Hurd-specific knowledge is
required, though.)
This is [[GNU_Savannah_task 5488]].
Possible mentors: Samuel Thibault (youpi)
Exercise: Try porting one driver from Linux 2.6 to run in the old framework.
The port needn't be elegant or complete; but it would be nice if you could get
it to work at least partially...
