When run a weston 10.0.0:
# export XDG_RUNTIME_DIR=/tmp
# weston --backend=drm-backend.so --use-pixma --tty=2
--continue=without-input
I got the following error:
drm_atomic_check_only [PLANE:31:Smart0-win0] CRTC set but no FB
...atomic core check failed.
weston: [atomic] couldn't commit new state: Resource temporarily unavailable
repaint-flush faild: Resource temporarily unavaiable
this is no display on hdmi.
I have to mask the the "start with plane disabled" logic in weston to
get it run correctly.

int err;
I am not sure if this is a drm driver or weston problem.
