EGLFS and Fbdev compatibility

  • Hi,

    I've an usb display :
    robopeak rpusbdisp using fbdev driver(?) to run

    i've read :

    and i'm trying this tutorial :

    Because i'd like to get native opengl/3d display without x server latency on my usb display.

    Maybe the answer is obvious but does a buffer/display compatible with LinuxFB makes it also compatible with EGLFS ?
    EGLFS is a layer above LinuxFB and will write buffer on /dev/fbX or it uses another system ?

    Thank you
