Hi Andrey, thank you for supporting. Actually, i am not sure if i need 'lima' driver or not... Because i run a simple web based (Javasctipt) GUI application in firefox in fullscreen kiosk mode. It has only two tabs (contexts) with fixed size without scrolling, a few buttons and window space for playing video on top of all without desktop environment. GUI application is very simple. I am not a web programmer but i know that i am not using any specific openGL code in web application. Maybe lima can help with CPU load because no matter how simple my GUI application is, it does not run smoothly when i switch between these two tabs. CPU can take more than 50% during switching and showing different contexts to the user. Anyway i also tried to load Lima driver and i got /dev/dri/card0, card1 and renderD128 but i am not sure how to test it.
When i try to load xwindow or kmscube i get following error message: root@olinuxino:~/workspace# kmscube gbm: failed to open any driver (search paths /usr/lib/arm-linux-gnueabihf/dri:\$${ORIGIN}/dri:/usr/lib/dri) gbm: Last dlopen error: /usr/lib/dri/sun4i-drm_dri.so: cannot open shared object file: No such file or directory failed to load driver: sun4i-drm kmscube fail at this point but xwindow show only this error and continue running. I can run gui application after xwindow is started. My LVDS display is working well and one of my issues is how to put decoded video to a specific location in GUI application. After the video is decoded by cedar VE it is in YUV NV12 RAW format. I have to scale it to another resolution and show it inside of GUI application. On legacy kernel i used Display Engine and /dev/disp device node for this purpose. Unfortunately on mainline /dev/disp vanish and we are forced to use drm driver instead of it which is if i understand well the same Display Engine driver in the background.
