Phoronix: AMD Posts Updated Linux Patches For P-State Core Performance Boost

While AMD P-State driver's Preferred Core support was merged for Linux 6.9, another notable addition to this driver is still undergoing the patch review process: Core Performance Boost...

Not only that these patches supposedly fix setting min/max CPU cores frequencies, a feature I requested almost two years ago.

Sadly, you'll have to wait until 6.9 before you can use this.

At least amd-pstate should now be better than intel-pstate which AFAIK lacks frequency control.

Ah so hopefully 6.10 by the end of the year will have everything working then.

Still faster then GNOME process with development and merging PRs.

I was going to make a joke about being triggered by the grammar and small font, but I can tell English isn't your first language so I'm just going to say that "then" is used when referring to a point in time and "than" is used when comparing, you should include "the" before GNOME (it's a direct article), and I think you just forgot the word "get" in "get triggered".

Finally no more cpupower hacks.

If I'm understanding correctly, this patch series seems dubious. It's appears to be just a special button for setting scaling_max_freq = nominal_freq on all cores. If userspace wants to do that, can we already just... do it? Why does there need to be a particular sysfs file named after some BIOS setting?

What am I missing here?

If this sentence in your linked documentation is true, it doesn't seem to lack?

intel_pstate allows P-state limits to be set in two ways: with the help of the max_perf_pct and min_perf_pct global attributes or via the scaling_max_freq and scaling_min_freq CPUFreq policy attributes.

Good catch, sorry for the misinformation, I glanced over it and was quite inattentive. I need to check how it works on my laptop because it looks like this feature wasn't available in this driver earlier.

Perhaps somebody can help here.
I'm running proxmox on my zen2 threadripper.
Promox uses a debian based distro.
Is there any popular kernel release (with a debian-based repo) which contains these patches which are not upstreamed yet?
I keep building my own kernel, but it's tiresome to keep track of the patches.
