Linux-Based XanMod Kernel Tests

[post-factum]

I did not know that, I was talking about sites mentioned on Your forum and http://77.244.44.75/. I must have mixed something in this old head of mine. Sorry to hear that and I know how hard is to get any donation and HW does not grow on trees... All the best.

As I stated many times before, 3rd-party binaries aren't (and weren't) supported by any means.

Talking exceptionally about official pf-kernel binaries, they were abandoned almost 3 (three) years ago due to lack of donations. Why even remembering that? Now official pf-kernel binaries are provided for 2 CPU architectures for Arch Linux only.

I did it as many times before (as much for myself as for others that do not have full know_how to do that themselves) but I do know that many users prefer (no comment) cooked versions... You did provide them for quite some time so I (wrongly) presumed that it would continue. I know how big and time-consuming is such endeavour so do not get me wrong. Just a suggestion, I'll leave it at this.

Compile it by yourself?

How to obtain binaries for newest pf-kernel?

Compile it by yourself?

[zika]

I believe one should note that xanmod kernel is derived from pf-kernel, so one should examine pf-kernel as well. https://pf.natalenko.name/

It is clearly noted on the very first page of Xan forum:

XanMod is a Linux kernel compilation of pf-Kernel base with custom modifications. Optimized for take full advantage in high-performance Workstations, Gaming Desktops, Media Centers and others.

with all links given...
Support for pf-kernel (apart from source) kind of lost momentum after abrupt closure of its forum. Yes, most of us learned about Xan kernel on pf-natalenko forum. But, it must be said, that Xan kernel went since at least couple of steps further. How to obtain binaries for newest pf-kernel?

There should probably be a link to Xanmod in the article for the sake of completeness.

Two points to consider after seeing the results. The release tested uses, by default, the interactive mode from ck's bfs v0.467. In graphics applications this behavior can have a negative effect on results.
To turn off:

echo 0 > /proc/sys/kernel/interactive

In next release will disable interactive by default.

Now about the uksm. It is not recommended to run benchmarks immediately after the boot because it uses processing peaks in the meantime. I will improve this point as well.

Thank you Michael.

Did you run the test profile with PTS? Or manually set it up similarly? http://openbenchmarking.org/innhold/...955138fbc648ad
