I believe the Panfrost DRM driver may only be for the GPU. Based on the dts files in arm64/rockchip/, this is the pipeline of the gru-kevin setup that I understand. rk3399-vop (Big/Lite) -> rk3399-edp -> sharp,lq123p (edp-panel) The setup seems to be using the drm/rockchip drivers for the display controller and for the bridge. > > When it boots in console mode, the blinking of the cursor keeps the display > on. > If it is turned off via /sys/class/graphics/fbcon/cursor_blink, then > the display briefly shows each key press presented on screen for less > than one second and then powers off. > > When starting the graphical mode (wayland), if there are no > applications drawing on the screen, the only way to keep the display > on is by continuously moving the mouse. > Okay! I will have a look through the drivers. In the meanwhile, please do report back if you find any other observations. -- Regards Aradhya
