thanx Laszlo for the fast reply. Weston indeed is working pretty well, but two issues: * is "wasting" a 10% of CPU power and * we are finding some issue on the Qt setting the right display "programmatically".
for example this invocation of the example app *hellowindow* was displaying TWO rotating trolltech logos in the same head. */usr/lib/qt/examples/opengl/hellowindow/hellowindow --multiscreen -platform wayland* on a dual head desktop PC instead, the windows are shown on different screens. using the mouse can bring smoothly the rendered windows from a screen to the other and back.. puzzling! that's why we were trying to test the "lighter" EGLFS approach. i appreciate a lot your confirm about ELGFS_KMS being the right "device integration" for accessing the rendering pipeline with DRM/KMS (the MALI keyword on eglfs_mali is going to mislead a lot people..). we'll check more hardly this path now. on the other hand, the RK3288 is a little different beast, as AFAICS it has a Midgard core instead of Utgard (MP4xx), but maybe it could be a worthy experience testing it too, i have a Radxa Rock2 lying around, indeed.. let you know, anyway..
