Comment # 97
on bug 110674
from Tom B
I've been investigating this: https://github.com/torvalds/linux/commit/94ed6d0cfdb867be9bf05f03d682980bce5d0036 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.
