For the +reporter this means that the display will always run at 40Hz which is +quite annoying. This may be due to the mode comparison. + +But there are some other potential issues. The choice of alt_fixed_mode +seems dubious. It's the first non-preferred mode, but there are no +guarantees that the only difference would be refresh rate. Similarly, +there may be more than one preferred mode in the probed modes list, and +the commit changes the preferred mode selection to choose the last one +on the list instead of the first. + +(Note that the probed modes list is the raw, unfiltered, unsorted list +of modes from drm_add_edid_modes(), not the pretty result after a +drm_helper_probe_single_connector_modes() call.) + +Finally, we already have eerily similar code in place to find the +downclock mode for DRRS that seems like could be reused here. + +Back to the drawing board. + +Note: This is a hand-crafted revert due to conflicts.
