Dual Independent displays with NXP i.MX8QM SoC

[Abdul Redwan]

Hello Wayland Developer Team,
We are working on dual display use case based on i.MX8QM SoC for an Automotive Rear Seat Entertainment application which has Audio/Video playback supporting two users in parallel. As well defined, we could achieve extended display with Wayland/Weston service (Unable to choose the location of the secondary display for the applications except with the help of mouse pointer) but we need dual Independent displays hence tried below options without any luck

1. Kiosk shell (We believe it allows to locate the display with app-ids field under output)
2. Two Weston service (is this only possible with two DRM devices? not with one?? drm-backend seems to be crashing for the second service)
3. Segregating user points for each display like dedicating touch inputs for each display in kms.conf for QT Wayland, ivi-shell, etc

We aren't very sure if above methods we tried is properly executed, any other methods we have missed or not if we could get some working logs/steps so that we can verify the same. Also, if you could let us know if there are any limitations with dual independent display wrt Native Wayland/Weston (Both users in Parallel accessing two displays able to do extensive Audio/Video playback) it would be helpful

Thanks,
Redwan
