Dear All,

What is the most effective/optimal/recommended way to wait for DRM_MODE_CONNECTED status?

This is to make sure when disply manager (uses drm apis) starts and if it do not get the DRM_MODE_CONNECTED status as some dependent driver is still loading and setting up (e.g. serializer driver) in that case what is the best way to wait for it?

Should I poll the state repeatedly in a loop? Will this value be automatically get updated? Should I close() the DRM device and re-open() it again? Is there any interrupt/callback we can register for to receive updated for this connector state?

Thank you.

Best Regards, Vikash
