My tests with the very lastest OMAP boards: I found a 20% speed improvement on the OMAP between kdrive fbdev KAA and xorg fbdev EXA. However I didn't not use the most recent version of kdrive for the comparision, so I don't know what the difference is now. I found no memory usage difference between the newest kdrive and newest Xorg. > The development effort of writing a new kdrive server (based on Xfbdev) > vs writing Xorg driver for a new hardware? I guess kdrive is easier and > cleaner, maybe because I'm not at all familiar with Xorg development. It is a harder to get started with Xorg because there's quite a bit of code that you need to get started. However writing the Xorg driver is much cleaner. It is a separate driver, and can be compiled etc completely independently of Xorg. For KDrive, however, it's much more 'built-in'. Also there are things you can do with an Xorg driver that you can't do with kdrive. For example manage your own pixmap memory - essential if you have a UMA system (unified memory). So basically I would join the chorus here in recommending to go with Xorg John _______________________________________________ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
