The DRM modesetting code preserves compatibility with the fb interfaces, so if you write a DRM based modesetting driver, fb applications can run on top unmodified. Also, the existing fb stuff won't go away (though some maintainers may choose to replace their fb drivers with DRM modesetting based ones). Which type of driver to write just depends on what your hw is capable of and whether you feel the slightly higher complexity of a DRM based driver is justified (it probably will be if you ever plan on adding 3d support to your stack or if you want to exploit the fancy output control that the DRM based API provides). Hope that helps. Jesse ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
