Thanks for all you tiresome work dealing with the feedback from the community and me and thank you for the cooperation so far. You have managed to convert this display driver from something based on a wrong abstraction to a driver that not only are using the latest DRM infrastructure but also now have the correct structure and correct bindings. There are still things we can improve - but rather than doing it alone we are better served with the driver applied to drm-misc-next so we are more that can help and maybe even contribute. Patches applied to drm-misc-next. Sam _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
