Fixing this, [[!GNU_Savannah_task -5485]], requires two steps: the first is to port some other kernel's drivers to -[[GNU_Mach|microkernel/mach/gnumach]] so we can get access to actual sound -hardware. The second is to implement a userspace server ([[hurd/translator]]), -that implements an interface on top of the kernel device that can be used by -applications -- probably OSS or maybe ALSA. - -Completing this task requires porting at least one driver (e.g. from Linux) for -a popular piece of sound hardware, and the basic userspace server. For the -driver part, previous experience with programming kernel drivers is strongly -advisable. The userspace part requires some knowledge about programming Hurd -translators, but shouldn't be too hard. - -Once the basic support is working, it's up to the student to use the remaining -time for porting more drivers, or implementing a more sophisticated userspace -infrastructure. The latter requires good understanding of the Hurd philosophy, -to come up with an appropriate design. - -Another option would be to evaluate whether a driver that is completely running -in user-space is feasible. <!-- TODO. Elaborate. --> - -Possible mentors: Samuel Thibault (youpi) - -Exercise: This project requires kernel (driver framework) hacking as well as -some Hurd server hacking; so the exercise should involve either of these, or -even both. You could for example port some newer driver to run in the existing -framework (see the [[device_driver|driver_glue_code]] project description), or -try to make some fix(es) to the [unfinished random device -implementation](http://savannah.gnu.org/patch/?6088) created by Michael -Casadevall. |
