Pekka,
any possible workaround do you know to support independent crtc clone
within weston? right now it is very important product feature.
for example, force weston to identify only one screen, and sync copy
the screen to 2nd screen and call the drm api of 2nd screen?
i don't think the so-called "clone" supported by ivi-shell is what i want.
