I'm trying to figure out why my compiled weston works fine on RPi3 vc4:
But same image fails on RPi4 v3d:
I suspect the failure is in Mesa EGL, but I have both vc4/v3d drivers built.
Does anyone know if Raspbian applies any v3d related patches to weston or mesa that has not yet been merged upstream?
If I build the swrast driver, it just falls back to software rendering and starts up normally (but slow, obviously).
If I add "--use-pixman" same thing.
This is how I build mesa and weston:
Also, any help on how to get more debug info out of weston/mesa would be appreciated.
I've tried a few environment variables like LIBGL_DEBUG and EGL_LOG_LEVEL but they don't produce much.
