AMD idle speed higher with kernel 6.13 than with 6.12

Support Kernel
1

After the Feb 4 testing branch update, which went just fine across the board, I also tried out the 6.13.1-2 kernel update.

On my antique Intel laptop there are no issues.

On both my AMD machines, (Zen3 desktop and Zen4 laptop), both using tuned 2.25.1-1 (balanced power profile) for power management, the CPU idle speed jumps under 6.13 as compared to 6.12 with no other changes–simply making the appropriate choice in the grub menu.

On the desktop, idle speed jumps from 550 MHz to 1737 MHz. The laptop soars by a similar amount. The laptop is my testing device. I had previously experienced the same matter on it under 6.13.0-something, but figured, it’s a point zero release.

I’ve messed a bit with the tuned settings, but honestly, getting into the weeds with it is over my head. All I’ve been able to do is increase the idle speed to the advertised base clock, ~3.9 GHz. Yay! I can make it worse!

I realize this is probably an upstream issue somewhere. If you have thoughts on a fix, I’d be delighted to hear and try, but I post mainly to report the matter for my betters to scratch their heads and grumble over.

EDIT:

For the sake of completeness (READ: I have nothing better do while I wait for the laundry to finish) I fired up the laptop and installed 6.14.0rc1-2. Same as 6.13.

The laptop’s idle speeds are
6.12 0400 MHz
6.13 1099 MHz
6.14 1100 MHz

It is probably to do with the recent change to the amd-pstate-epp governor which sets the idle speed to the lowest non-linear frequency rather than the lowest frequency:

[PATCH 0/3] cpufreq/amd-pstate: Set initial min_freq to lowest_nonlinear_freq

According to the AMD architectural programmer’s manual volume 2 [1], in section 17.6.4.1 CPPC_CAPABILITY_1" lowest_nonlinear_perf is described as “Reports the most energy efficient performance level (in terms of performance per watt). Above this threshold, lower performance levels generally result in increased energy efficiency. Reducing performance below this threshold does not result in total energy savings for a given computation, although it reduces instantaneous power consumption”. So lowest_nonlinear_perf is the most power efficient performance level, and going below that would lead to a worse performance/watt.

Also setting the minimum frequency to lowest_nonlinear_freq (instead of lowest_freq) allows the CPU to idle at a higher frequency which leads to more time being spent in a deeper idle state (as trivial idle tasks are completed sooner). This has shown a power benefit in some systems. In other systems, power consumption has increased but so has the throughput/watt.

I haven’t used kernel 6.12 for a while (I was using the 6.13RC from November until today), but I do recall my idle speed being lower on 6.12 than 6.13. I also recall my System Monitor sensor widget showing my CPU constantly switching between the min & max frequencies while idle, whereas now it sits near the lowest_nonlinear_freq most of the time when idle.

Thanks, Scotty. I appreciate the links. As I suspected, it’s clearly an upstream issue.

Read through everything, then through the readmes, other references, and the man pages of tuned.

It seems a reasonable idea for datacenters and other production environments. Performance/watt makes sense when there’s something actually performing. When performance is zero, it’s a lotta extra watts burning for more nothings/second. I’m not so sure it’s right for someone whose computer spends most of its ops wondering if I’ve gone for a nap.

Or why I type so darned slowly. It seems like it’s just stuffing in more NOPs between keypresses.

Then again, just turning the thing off would save even more power…

I’ve not yet done as extensive testing as you seem to have done, but I have noticed both units run a wee bit hotter at the higher idle, enough so on the desktop that the fans cycle.

On further testing I may decide to go the way you have, but for now, I think I’ll stick with 6.12 and test and research further. Another possible fix could just be recurving the fan response.

You can also use the cpupower frequency-info command (you may need to install the cpupower package) to see the current settings for your CPU. Here’s the output for my Ryzen 7 5800H:

That will have to wait until the weekend. I’ll need to uninstall tuned before looking into cpupower. Per the tuned readme in the source package here Releases · redhat-performance/tuned · GitHub :

# TuneD: Daemon for monitoring and adaptive tuning of system devices.

(This is TuneD 2.0 with a new code base. If you are looking for the older
version, please check out branch '1.0' in our Git repository.)

How to use it
-------------

TuneD is incompatible with ``cpupower`` and ``power-profiles-daemon``. If you
have these services, uninstall or disable them.

I’m off to my retirement gig at the library.

I use tuned (with tuned-ppd). I also have cpupower installed just so that I can check my CPU speeds. It is fine to have both of them installed - as per the tuned instructions you just have to make sure the cpupower service is disabled:

I messed around with this over the weekend. Learned some too. I eventually found a combination of things that seems to fit me well.

I have to accept the decisions leading to the kernel patch. Those folks are much smarter than I am and I can’t change their decisions anyway. The higher clock at idle remains.

So I focussed mainly on tuned. I had been using the balanced profile. After experimentation, for my use case, the powersave profile makes most sense. Using it, my CPU idle temps (a reasonable proxy for energy use) dropped 7C to 34C, which is about 9C higher than ambient. This, despite the 2.2x higher clock.

Response times in the apps I use routinely seem no different, even though the powersave profile limits the clock to the advertised base of 3.3 GHz (mis-reported above as 3.9, sorry).

I did notice the difference when building AUR packages, but it’s easy enough to switch to the throughput-performance profile before–or even during–a build. Doing that, thermals then limit the clock. Had no issues with thermal limits on most things I tested.

However ungoogled-chromium hit the thermal limits pretty hard at max clock, then throttled back the clock while maintaining 100% usage on all 16 cores and 32 threads. Same on the laptop with a Ryzen 7 7840U (8C/16T). And that’s the first time I noticed any significant difference between the two computers.

But, since my actual routine use case barely nudges the throttle on my my third computer–an ancient Intel laptop (2C/2T @ 1.5 GHz)–let alone the beast of a desktop, or even the Framework laptop, running in powersave is perfectly fine for me in both instances. Now settled on 6.13 on the desktop, 6.14 on the lappy.

Thanks for pointing me in the right direction.

PS: There’s a similar thread over on Arch Forums, but I’m not smart enough to pass the test to create an account, so I couldn’t refer that poster to this. Perhaps you or someone else can?

Having this issue as well on 6.13.1, noticed my 5700X no longer idling to 500Mhz.

I am using the non-epp amd-pstate driver btw and it idles my 5700X at around 1700Mhz. For now I have switched back to 6.12.

On Arch forums it is marked solved though it only relates to amd-pstate-epp and not for amd-pstate usages. Here is the link to the thread:

I’ve just noticed this thread, albeit a little late.

From 2023.NOV to 2025 MARCH, the minimum clock speed in my environment is 550MHz. any kernel. 6.12-6.13-6.14

I always visually check it after every reboot. with cpupower-gui.
Personally, I am satisfied with the current state of AMD_PSTATE(active).

Is there any new news on this @BG405?

My backup an AMD Ryzen 3600, running Fedora Kinoite, was just updated to 6.13.5. And now exhibits this same issue.

I have it configured using amd-pstate-epp with the KDE Powerprofile set to Powersafe. And that idles using Lowest Non Linear Frequency (2.24Ghz) instead of the Lowest Frequency (550Mhz) according to cpupower.

So for me two this is AMD systems (Zen2 and Zen3) on which this occurs, both when running kernel 6.13.x, with amd-pstate or amd-pstate-epp,

Update:

Found one thread on kernel.org regarding a commit from an AMD pstate dev on the amd-pstate driver for 6.13. (amd-pstate 6.13 content (10/22/24))

This update seemingly has caused this high idle issue at least on AM4 Zen2/3 CPU’s and it excludes any kernel past 6.12. At least for now.

Update the amd-pstate driver to set the initial scaling frequency policy
lower bound to be lowest non-linear frequency. This will have a slight
power consumption impact but should lead to increased efficiency.

So how can we draw attention to this issue?
Mailing the AMD dev that made the commit and bring this to his attention?

I’d say it probably wouldn’t hurt to contact the developer, although it’s already likely being worked on.

I don’t have one of the affected CPUs so can’t test these things myself; I’m running Intel presently, these are using the intel-cpufreq driver.

Intel indeed has no issues with this (got two intel system here as well) and to be clear this is not a bug while it might read from my wording.

The idle freq floor has been raised to the lowest voltage stage of the CPU, which is the at Lowest Non Linear Frequency and differs per CPU SKU.
The CPU gets into higher states faster/sooner, increasing performance/efficiency as the commit stated.

In my case I did not notice any perf increase, I set CPU governors through profiles for the loads needed, the only effect this change has in on overall temperatures. Since the 5700X goes into higher pstates sooner while on 6.12 on Conservative it kept nearer to Lowest Non Linear Frequency.

Anyway. I’ll email the dev with a question if he sees benefit to seperate amd-pstate=passive from active for this change.
