Zen 4/5 optimized Repository Testing

Ill look into enhancing it.

Yes, looks like that proton does not like avx512. I will compile it based on avx2.

Okay, thank you! Would you prefer Steam-Nativ over Steam-Runtime ?

Personally I use steam-native most games. As long games work with native - go for it. Specially on CachyOS in Native games you can see a great bump in performance (CS2 for example.)

Okay, with Lutris → Epic Games → Remnant From the Ashes that CachyOS Proton also not work.

With Proton Experimentel it does work.
But I don’t know how to provide a log.

Oh? lutris does not have proton-cachyos.

There is only a wine variant of it.

Ahhh my fault I mean "System (cachyos-9.0 (Staging)). Yes the wine version of it. With that it does not start anymore. That was working before. There it says Proton - Experimental. When I select this it does work.

Thanks, Ill check it out with the maintainer.

Awesome, beside of that the game runs smooth I play it with a friend right now. He say’s he can’t see my game but with the Shift+F3 invite it was successful and he joined so that we can play together. G-Sync is working too.

Is System (cachyos-9.0 (Staging)) in Lutris wine variant of proton-cachyos?

that’s probably the wine-cachyos package.

Are there plans for zen3 repo?

No, Zen3 doesnt offer too many benefits compared to the v3 repository.
Since the base x86-64-v4 only enables some base x86-64-v4 extensions, we have decided to push Zen4 further.

Adding an extra repository would require another 70Euro Server per month, which we are currently not capable of. We are already investing all donations into CachyOS.

After updating my pacman.conf file for the update, I am getting the following error message when running pacman -Scc

error: config file /etc/pacman.d/cachyos-v4-mirrorlist could not be read: No such file or directory

I am updating the pacman.conf file from v3 and verified I have a supported machine (7800x3D).

Has anyone ran into this? If so, how did you get past it?

You need to install cachyos-v4-mirrorlist

Thank you for the reminder! Updates pushed and I do notice a difference. Excellent work on this!

I have been testing zenv4 repository on an AMD Ryzen 9 7950X. The performance is better because the CPU spends less time building and compiling SW, but there is a problem with stability. I am getting random hard resets, and the PC reboots by itself.

I tracked down the problem with the linux-cachyos v6.10.x series. It does not happen with linux-cachyos v6.9.x or the Arch Linux kernel.

I am not sure if there was something new added in Cachy Sauce Kernel for v6.10.x or if it’s a problem with the Linux kernel upstream.

Mhm, I do not see this on the 7950X3D at all.
Do you see anything in logs? Related to amd cpu stuff we have only included the amd pstate patches from 6.11. You could test too the 6.11 kernel.

Maybe its due being compiled with Zen4 optimization. Could you test the same kernel from the v4 or v3 repository?

I have tested linux-cachyos-bore v6.10.6-1 with Zen4 optimizations, and the auto-reboots are not happening anymore. The problem is with linux-cachyos v6.10.x. Could it be related to the scheduling feature? I believe this is the only main difference between both kernels.

Mhmm. That seems unlikely. The only difference between “linux-cachyos-bore” and “linux-cachyos” is the sched-ext framework… :confused:

Updating after more testing in AMD Ryzen 9 7950x …

Reboots itself after two days of uptime:

  • linux-cachyos-bore v6.10.6-1 with zenv4 and v4 optimizations

  • Linux kernel v6.10.x from Arch Linux without optimizations

  • Linux kernel v6.10.x from Manjaro without optimizations

Reboots itself between 6 hours of uptime:

  • linux-cachyos v6.10.x with and without optimizations.

No issues:

  • linux-cachyos v6.9.x with zenv4 and v4 optmizations.

Current testing:

  • linux-cachyos v6.11.0-rc4-2 with v4 optmizations

This looks more like a General 6.10 issue.
