Arch Linux User Repository

The repository for linux-rt and linux-rt-lts has moved to a new location.

If you use the custom repository, please update your pacman.conf accordingly, as the other one is going away by the end of the month (January 2021)!

If you have time to do benchmarks between this setting and e.g. the default CONFIG_HZ=300, please do share!

I had no time to do so and still don't have got the time. However, I keep it in mind. Yesterday I build 2 longterm kernels that only differ by CONFIG_HZ [1]. If I should do any testing, I'll report back. Don't reckon that this will happen soon, if at all. I just want to inform, that it's still on a todo list, it's just not that important to me.

Has got anybody who is using USB devices, excepted of habys, noticed a difference?

5.10.12.26.arch1-2 seems alright.

@rvalles, @blackhole: Yes, I am also experiencing issues. I have already found the culprit in the config and will release a fixed version and rebuild for glibc 2.33 later today.

I have also big problems with latest linux-rt:

Error messages at boot about udev that cannot initialize socket, after it will go to recovery console but keyboard is not working.

Tested in 2 different computers and 2 different USB keyboard

linux-rt-lts is working fine and also archlinux last kernel

These systems are fully updated to today.

Latest PKGBUILD, 5.10.12.26.arch1-1, not working so well. 5.10.8 worked fine.

USB keyboard not working, lvm partitions not found in the LUKS container. Same results with fallback initrd. This is on a Thinkpad x395.

Mainline "linux" package (5.10.12-arch1-1 installed about the same time) is fine, so I discard mkinitcpio as culprit.

Could you add the patch from:

https://gitlab.freedesktop.org/drm/nouveau/uploads/8844d508dbe905daf9802007dc1c7e03/0001-drm-gpu-nouveau-dispnv50-Restore-pushing-of-all-data.patch

Without it, nvidia nv50 cards are freezing frequently (see bugreport https://gitlab.freedesktop.org/drm/nouveau/-/issues/14). I'm using it for few days now and it solved my problems.

Thanks

why clone the linux-rt repository which weighs 1.6GiB instead of just downloading the 176MiB source in .tar.gz format? This would save storage and cpu (during the git deltas resolution)

Getting the same error as @cavilory on an Asus TUF A15. EDIT: sorry for the noise, seems it was caused by a buggy sd card reader.
