All the outputs on my card are cloned. This patch unclones most of the outputs, keeping cloned only the outputs with same "Output". Namely
- VGA has no clone (output is DAC A) - S_VIDEO and DVI-I/analog are clones (output is DAC B) - DVI-I/digital has no clone (output is TMDS B)
I don't know whether DVI-I/digital should be a clone of S_VIDEO and DVI-I/analog (I don't have a DVI-I splitter to test whether the 2 outputs are independent). I don't know whether the possible_crts should be modified as well.
Hm. I don't understand what you intend to do.
All outputs on Radeon cards can be attached to any crtcs - and that
should be reflected by the possible_clones data field.
So it *is* possible to use only one crtc to show the same data on
different outputs, and save power in this process.
There is no drawback in having this possible, other than the xrandr
application having several bugs with respect to this feature. I have
fixed all bugs I could find in the upstream git version.
