Not much. See http://freedesktop.org/wiki/Software/Xgl, but the major requirements are: NV_texture_rectangle ARB_texture_border_clamp ARB_multitexture ARB_texture_env_combine > Which modifications to a driver are necessary for EGL? > Wich parts of the driver (DRM, fb, DRI) have to be modified? The drm/fb layer has to be smart enough to set video modes, and the DRI driver needs some new entrypoints to translate that functionality to the EGL_MESA_screen_surface extension. > Will Xegl run fast enough on old hardware like the > RagePro 3D or the SiS 305 or Sis 6326? Well no one has tried, so no one knows yet. mach64 will likely have correctness issues due to its craptastic alpha combiner. I would expect acceptable (for some value of acceptable) performance for cards at about the voodoo3 or rage128 level, and anything below that really depends on how clever the driver is and whether the hardware has useful features we can take advantage of. I'm hoping to get back to hacking on EGL stuff once 7.0 lands. - ajax
