All three major GPU device classes have KMS support (Intel, ATI, and nVidia). If you want it for a particular device, you can always port it over. As for fbdev emulation, what's still using it? There's nothing stopping projects from converting over; X and Wayland can already handle KMS APIs just fine. > I know the graphic driver situation is quite bad on Linux, especially > on the embedded world.

Probably for a couple of reasons: 1) inertia: fbdev has been around a lot longer, and provides most of what embedded devices need anyway 2) feature set: why bother doing a full KMS driver if you're not going to use any of the additional features it would provide (output management, memory management, execution management) Jesse _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
