Like we have drivers which are below 300 lines with all the helpers taking care of everything, this shouldn't be too tricky. And if no one cares enough for that, then imo let's just keep this in staging and let it quietly&slowly pass away. At least from the people who've been active in any kind of display development the past 6+ years (which is roughly when Tomi abandoned fbdev as last active maintainer) the consensus _is_ that drm drivers are simpler, quicker to type (once you got hold of the subsystem and all its helpers at least), and adding new fbdev drivers just makes no sense at all. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch
