6.10 Kernel Testing

@here

The linux-cachyos-rc kernel is more or less it its final version and we can start the testing for the upcoming major release.

There kernel is already tested internally in the team and it is looking in a great spot, some highlights added from our side:

  1. amd-pstate cpb boost is now included with the latest patchset, this can be controlled via powerdevil/power-profiles-daemon. Setting it to power-save, will disable boost. This can majorly improve the temperature on laptops
  2. Crypto Patches for Dynamic avx10/avx512/avx2 got updated to latest

Besides that all patches, which are carried in 6.9 are also included in 6.10.

Upstram Major changes are:

  • Filesystem improvements
  • Steam Deck IMU support
  • EEVDF Scheduler improvements
  • ROCm improvements on APU’s

Pending is currently the intel-pstate patches, which will handle the P/E Core handling - sadly I did not got much input yet from intel users.
In case that anyone wants to test them, they can be found here:

You can install and test the kernel with following command:

sudo pacman -S linux-cachyos-rc linux-cachyos-rc-headers

If NVIDIA additionally:
sudo pacman -S linux-cachyos-rc-nvidia (or linux-cachyos-rc-nvidia-open)

If ZFS Filesystem:
sudo pacman -S linux-cachyos-rc-zfs

The final 6.10 Kernel will be released in around 2 weeks.

sudo pacman -S linux-cachyos-rc linux-cachyos-rc-header
error: target not found: linux-cachyos-rc-header

missing an ‘s’ at the end, should be,
sudo pacman -S linux-cachyos-rc linux-cachyos-rc-headers

Fixed, thanks!

I’m getting some heavy display corruption with this kernel (everything is fine with 6.9).

AMD gpu + zen4 on default KDE with wayland, cachyos mesa-git: moving the mouse and windows corrupts the display. When nothing is moving everything is fine.

The screen corruption also happens during system shutdown and boot up (on the terminal tty). → every time something is moving the corruption appears.

Would you mind, to test with stable mesa?

I wonder, since we do not patch anything DRM related. Maybe its an upstream issue.

If you could provide me logs, I will directly forward it to AMD

Same problem with the stable mesa.

Great, here.

Thanks!

Is this log, after the issue is happening?

Yes, this is cachyos-bugreport.sh just after kde login in the kde terminal, while the issue is happening (it is always constantly happening. The 1/6 top of the screen is flickering and completely corrupted. 5/6 of the screen below this is fine).

The problem is still there with 6.10 rc7.

I hope you have informed them?

Sorry, can you create a ticket at Issues ¡ drm ¡ GitLab?

Maybe with a video ?

Done.

I also tested the mainline 6.10rc7 kernel. Same problem.

I also tested the mainline 6.10rc7 kernel. Same problem.

We do not include any DRM patches, and this is pretty much intended.

No issues, everything working with AMD Ryzen 9 7940 HS APU on ZEN 4/5 optimized Repository.

Welcome!
Really glad to hear that everything works out well. The release is planned for tomorrow :slight_smile:

The linux-cachyos-6.10 release kernel is still broken on several amd 6000 series cards (6750, 6900,…) with severe display corruption making the system unusable.

Why have you knowingly/willingly manually pushed it (seeing as arch doesn’t even have it in testing yet) without even reverting the commit that broke it?

Because people can just hold/use the archive. Just because RDNA2 has issues, it should be not blocked for other configuration.

Also, we never block a kernel as long their is no heavy regression in terms of not bootable, segfaults or equal. Upstream needs to fix this, but since their is no activity seen there is no reason to wait.

If we care about every hardware issues, then we can never push a kernel and need to stick to and long term lts, like 6.1

I’m very disappointed to hear that cachyos is not a solid stable os for people to get work done, but just a gimmick playground for geeks to play around with.

You KNOWINGLY ship a BROKEN kernel on one of the major gpus, and expect users to spend their time troubleshooting and fix config files, etc…

It works for YOU on YOUR hardware, so you don’t give a flying fuck about your users.

What a joke of a distro this now is.

And what is SO URGENT that you needs to shit this broken kernel so fast? Also, you could have reverted the patch that corrupts the display.

I have sent many people over to cachyos, but now, as people trust me when I recommend them something, I for sure won’t be able to recommend cachyos to anyone anymore.

Also, you could have named this kernel “linux-cachyos-unstable or testing” if it’s so URGENT for you to ship a broken kernel.
