...1ebdbe09e The code was updated to make it compatible with the current state of the driver. Here is how it now works. If the connection is DCB_OUTPUT_DP, call nouveau_dp_dpms() which does DP_SET_POWER and, if we are resuming, initiates DP link training by sending NV94_DISP_SOR_DP_TRAIN to have nv50_sor_mthd() call nouveau_dp_train().

Thank you. This, as you've seen, would appear to solve the issue. There's a little more to the power-down to be done however (such as shutting down the lanes at the SOR, which, yes, we never did before either), and potential races between the supervisor runn...
