Bug 111922

Can you bisect?

Not easily unfortunately as I've only been using Fedora kernels, so I don't have a build environment set up.

Issue still remains with 5.4.0-rc6 unfortunately. :/

Do you have any patches or commits I could try reverting? It's much easier building a test RPM here.

It should be something during the 5.2.0 merge window. Anything likely from that set?

Nothing comes to mind.

That's a shame.

I did find bug 111811, which looks very similar. Through that I found this patch:

https://www.mail-archive.com/amd-gfx@lists.freedesktop.org/msg40304.html

Unfortunately it does not solve the issue here. :/


Have you checked if you can reproduce this in a 2200G in your end? Or other Raven Ridge APUs?

Hmmm... I did get this from that patch though:

Not sure if it helps.

I finally got a build environment set up, and the winner is:

Which seems extremely odd given the contents of that commit. But I guess it makes userspace change behaviour in a way that provokes the bug?

I don't think bisect will get me further. Help?

Userspace only enables per flip tiling updates if the version of the kernel driver is new enough to support that feature.  Maybe this is related to the DCC changes in mesa.

Userspace doesn't know when suspend/resume is happening, so it can't hang on suspend/resume. My guess is it's something in DAL.
