Hi, > Please correct me if I'm wrong, but text-console emulation/scrolling on DRM is > currently unaccelerated and bound to Truecolour modes only, Yes. Adding support for formats beside argb8888 to the drm fbcon emulation shouldn't be that much of a problem though. Acceleration is harder. The scroll acceleration had issues nobody addressed for years, and on modern hardware it is simply not used, which is probably the reason nobody stepped up fixing things and it ended up being dropped. Bringing it back is much more work than just reverting the commits removing it. Also note that using a shadow framebuffer allows to decouple fbcon updates and scanout framebuffer updates. Can be used to speed up things without depending on the 2d blitter. take care, Gerd
