Namely if a plane, DVO port etc. is currently assigned to a disabled pipe, it can't moved to the other pipe until the current pipe is also enabled. To keep things simple just leave both pipes running all the time. Ideally I think should turn the pipes off if neither is active, and when either becomes active we enable both. But that would reuquire proper atomic modeset support, and probably a bit of extra care in the order things get enabled. v2: Reorder wrt. double wide handling changes Signed-off-by: Ville Syrjälä Tested-by: Thomas Richter Signed-off-by: Daniel Vetter --- Reading git-diff-tree failed
