KDE Linux has already done this. It works around a long-running bug in the AMD GPU driver, which I believe also affects my test laptop. Without the workaround, the system freezes and does not recover until a hard reboot.
You tested this on your test laptop and it solved the problem?
I didn't test it on my own hardware. After having spent so long on Cloud Hypervisor, I'm having to set myself up for Spectrum development again, and that is taking a little bit of time. However, the symptoms are identical to what many others have seen: a freeze that needs a hard reboot to recover from.
Did you manually work around the card0/card1 bug?
That bug would cause Weston to fail to start, but not to freeze once started.
Do the proposed upstream patches also solve the problem?
I do not know, but they aren't in any stable kernel release yet, and KDE decided they weren't willing to wait for them. I don't think it makes sense for Spectrum to wait, either. The bug breaks Spectrum on what I suspect is a significant amount of hardware. Panel self-refresh is a completely optional feature that only saves a small amount of power. I'm inclined to trust the KWin developers' judgement on this. If KDE Linux reverts this change, I will send a patch to revert it in Spectrum. -- Sincerely, Demi Marie Obenour (she/her/hers)
