I talked to #intel-gfx, they said the warn was pretty harmless and we could also just propose a stable patch to drop that warning. Though I'm also okay with backporting fixes.

I'll all for this. 4.6 is in the stabilization branch if you didn't notice already. josh ___ kernel mailing list kernel@lists.fedoraproject.org https://lists.fedoraproject.org/admin/lists/kernel@lists.fedoraproject.org

Regards, Hans Hi Fedora kernel team, If you look at: https://retrace.fedoraproject.org/faf/problems/ And look for skl_update_other_pipe_wm there, you will see that it is completely dominating the problem report stats (listed 4 times on the first page, 5 times on the second). As such I'm thinking about backporting the patches: http://www.spinics.net/lists/intel-gfx/msg95595.html To the Fedora 4.6 kernel. Some of the reported problems are only a WARN_ON triggering, but there are also quite a few cases of actually wrong watermark settings causing various real problems. These patches have been around for a long time, but they missed the 4.6 merge window, and then also the 4.7 merge window, they are in next now. But IMHO we should grab them now since the problems they are causing are too big to wait for 4.8 hitting Fedora. So I would like to backport these to the 4.6 Fedora kernel and have this completed before we start pushing 4.6 updated to updates-testing. This way we can use the entire Fedora 4.6 testing phase to also test the backported fixes. Before I spend time on this, does this sound like a good plan ? I've already discussed this within the graphics team and the consensus there seems to be that this is a good idea.

This does indeed sound like a good plan, and would be much appreciated.

Backporting skl_update_other_pipe_wm intel drm fixes to the Fedora 4.6 kernel
Hi Fedora kernel team, If you look at: https://retrace.fedoraproject.org/faf/problems/ And look for skl_update_other_pipe_wm there, you will see that it is completely dominating the problem report stats (listed 4 times on the first page, 5 times on the second). As such I'm thinking about backporting the patches: http://www.spinics.net/lists/intel-gfx/msg95595.html To the Fedora 4.6 kernel. Some of the reported problems are only a WARN_ON triggering, but there are also quite a few cases of actually wrong watermark settings causing various real problems. These patches have been around for a long time, but they missed the 4.6 merge window, and then also the 4.7 merge window, they are in next now. But IMHO we should grab them now since the problems they are causing are too big to wait for 4.8 hitting Fedora. So I would like to backport these to the 4.6 Fedora kernel and have this completed before we start pushing 4.6 updated to updates-testing. This way we can use the entire Fedora 4.6 testing phase to also test the backported fixes. Before I spend time on this, does this sound like a good plan ? I've already discussed this within the graphics team and the consensus there seems to be that this is a good idea.
