[PATCH 0/9] implement multi screen clone mode in drm-backend.so

[Jason Ekstrand]

Xiong,
I'm not sure that we need to go that far right now.  I'm fine for now with
just a config option.  My primary concern is that you should be able to
have three outputs A, B, and C where A and B are masters and C is cloned to
A.  In your original implementation it looked to me like it was only
possible to have one master and if you had three outputs then they would
all have to show the same thing.
