It’s a work in progress. At the moment he is pursuing another attempt at a new hybrid model for the page locking. It looks like as @tardy has posted working.

5.9 up and running here, with BMQ scheduler and futex_wait_multiple.
No issues so far, performance on the same level as 5.8.

EDIT: slightly slower boot time, but I’m not yet sure whether it’s a kernel issue or something else like recent updates.

AMD GPU users should be aware overclocking via sysfs seems to be broken for at least a few GPU models on 5.9

I’m not sureif the revert of the offending commit will be in point release or not

Edit:revert should be in point release https://gitlab.freedesktop.org/drm/amd/-/issues/1334

Is there a specific holdup in testing for 5.9?

I assume we won’t be getting 5.8.15 in the interim?

Arch never releases the first version of a major new release - they will wait for 5.9.1.
5.9(.0) is in testing.

As @torvic9 said.

It works fine if you “cherry-pick” it from testing though, it doesn’t depend on any other packages in [testing]. I’m running linux-zen that way on three systems (including ZFS and Virtualbox DKMS modules) without issue.

I’m slightly concerned about this AUR package:

5.9 breaks it, as expected, but the comments suggest that the maintainer is absent.

Also, this package seems to be orphaned:

Btw, I really hate Nvidia, if I haven’t shared that with you already…

I think the problems are due to a change in which GPL symbols are made available.
Here’s an article in German: https://www.heise.de/news/Linux-5-9-Neue-Kernel-Version-schliesst-Lizenzluecke-und-unterstuetzt-FSGSBASE-4929799.html
(sorry too lazy to look for an English article :slight_smile: )

EDIT: nvidia, do like AMD and go full GPL. Your closed drivers have been very good IMO. It won’t hurt you.

TKG may have updated things in their package but idk for that driver

5.9.1 just arrived. Time to hit pacman/yay :slight_smile:
