<pre>I've been investigating this:
<a href="https://github.com/torvalds/linux/commit/94ed6d0cfdb867be9bf05f03d682980bce5d0036">https://github.com/torvalds/linux/commit/94ed6d0cfdb867be9bf05f03d682980bce5d0036</a>
Because vega20 doesn't export display_configuration_change, it jumps to the
newly added else block and calls smu_display_configuration_change. This didn't
happen in 5.0.13. It's not the cause of this as I commented it out and it still
breaks.
I'll also note that pp_display_cfg->display_count is correct at this point, it
shows 2 for me with 2 screens connected. But why doesn't vega20 export
display_configuration_change? It has display_config_changed and I can't find
where that's called from so I wonder if display_config_changed should be being
called at this point.</pre>
