Listen Now: Luc's Heated Talk From X@FOSDEM

The most heated talk this year during FOSDEM in the X.Org development room was certainly the talk by Luc Verhaegen with his ambitions to clean up the Linux graphics driver stack. Building the entire X.Org stack can be a mess and there is certainly areas to improve upon in the development process and making it easier for end-users and others to test out this latest code. Luc's goal for this is to create unified trees for each driver that contain all of the driver-specific code rather than having various bits scattered all over the place.

Luc's proposal involves reorganizing the kernel DRM, separating out the various parts of the DRM, moving out driver-specific code from libdrm, splitting out the mode-setting / memory management components, and to modularize Mesa and provide a formal API for this graphics stack. Luc has done a proof of concept for this new unified tree design using his VIA xf86-video-unichrome driver and encourages other X.Org developers to do the same. Luc didn't expect this talk to be received positively by all developers that were there in Brussels, and that certainly was not the case.

Afterwards the polarized debate and discussion spilled into our forums. Luc's slides that go along with the audio can be found in this Phoronix article.
