Dell Latitude 5420 (i7-1185g7) Power limited #255

sameer · 2021-05-21T01:19:42Z

Hi there,

First off just wanted to say thanks for creating this, it's a really helpful tool.

I recently set up throttled on a Latitude 5420 and am running into power throttling on AC. cTDP-up gets set successfully but the package power still sticks at 15W. There are also errors around setting the temperature target and mchbar package power limit.

Is there something I can try to troubleshoot here? Let me know if there's any other information I should provide.

I guess that your platform is limiting access to those MSRs.

sameer · 2021-05-21T15:42:48Z

I read that undervolting was disabled to mitigate plundervolt on newer CPUs so I'm thinking that might be related. Or maybe there's some permanent BIOS setting that got carried over from Windows.

dcplaut · 2021-05-30T13:46:35Z

I'm having similar issues (same processor in a Lenovo X1C9), including the match ERR for MCHBAR PACKAGE_POWER_LIMIT. If I manually overwrite /sys/devices/virtual/powercap/intel-rapl-mmio/intel-rapl-mmio:0/constraint_0_power_limit_uw (as mentioned in the README under Static Fix), everything seems to work for a while, but eventually the embedded controller (or something) overwrites my change back to a lower value.
[Update: sorry, just noticed the TEMPERATURE_TARGET match ERR, which I don't have.]

I am having just this issue with the 1165G7 in a lenovo thinkpad.

similar to what @dcplaut mentioned, if I run the static fix it "releases" the power, but quickly something sets it back to 10w.

What I ended up doing is a bash script that runs as a systemd service in an infinite loop every 5 seconds and set the values (the static fix commands) if is connected to AC only.

That fixes the problem for me but I can't stop thinking, what's exactly limiting the processor to 10W? Is it bad what I am doing? setting constantly a limit for 44w?

My computer runs very hot when I am doing heavy compilation things and I can see the temperature going in highs 90C degrees and thermo throttling (which is good at that temperature!)

Perhaps someone has some light in this issue?

UPDATE: in a lenovo if you use Fn+l or Fn+m or Fn+h you can change the CPU performance mode. This made my processor go from running in 10w to 20w but still not enough to make it to 44w so running the script still makes it go faster.

sameer · 2021-06-17T01:18:43Z

UPDATE: in a lenovo if you use Fn+l or Fn+m or Fn+h you can change the CPU performance mode.

Is that BIOS-level or is that something you're doing on Windows?

academo · 2021-06-23T07:54:33Z

@sameer I do it in Ubuntu. Not sure if it can work in other distros.

mazzz1y · 2021-07-03T17:32:13Z

I think that it is Dell specific issue, not possible to fix it by 'static fix' on Latitude 7520. Please correct me if I'm wrong

Related issue: intel/thermal_daemon#293

sameer · 2021-07-04T02:26:23Z

Thanks for sharing that, I think you're right.

mazzz1y · 2021-07-04T09:54:13Z

What I see currently:

In Windows it works correctly(3.3-4.8ghz on max load)
Latest mainline kernel(5.13.0-1-mainline) doesn't fix it
Latest bios doesn't fix it(1.7.1 for my laptop)
It depends on laptop vendor. I have MSI laptop with the same i7-1185g7 and it works properly, one difference is: Dell show base_frequency as 1800mhz, MSI as 3000mhz. Maybe it's related

cat /sys/devices/system/cpu/cpu0/cpufreq/base_frequency
1800000

Load/Unload modules, disabling intel_pstate, tune tdp limits, changing thermal mode(quiet,cool,balanced,performance) doesn't affect this problem

please add details if you will find something, thanks

Yinette · 2021-07-23T03:35:35Z

@academo For me (Lenovo P14s Gen 2) Turning off SpeedStep in the BIOS meant that it stopped giving the OS control of the CPU power (in 21.04's case I think it is thermald, I could be wrong...) It probably still needs to run the static fix on boot, I am not too sure yet. I'm working to determine this.

EDIT: running in tandem with fix_lenovo running the static fix on boot seems to do the trick... Just have it as a simple oneshot service. If only I could get it happening before systemd comes up, maybe I could boot faster haha

snoopcatt · 2021-07-27T02:05:36Z

Hello, guys. Got same problem
My Latitude 7320 (i5-1135G7) goes 400MHz under any load. OS: Debian Buster.

With latest throttled it's possible to achieve only 1500 MHz.
Same result is with only echo 0 > /sys/devices/virtual/powercap/intel_rapl.../enabled.

Have you tried to boot Ubuntu 20.04 live?
it's kinda "certified for Dell" — https://ubuntu.com/certified/202010-28329

I haven't noticed any 400MHz drops while using LiveCD for an hour.
But, installing kernel from Ubuntu to my main system didn't help at all.

Please check post in Dell community forum: https://www.dell.com/community/Latitude/Latitude-5420-7420-7520-CPU-Throttling-Issue-on-Linux/td-p/7959019

So far nothing new. Waiting for a miracle or fix from Dell

JMKS87 · 2021-08-05T14:10:38Z

Titular laptop & CPU Linux user also. I made some research & experiments.

In hot ambient (>25C) it behaves really bad, ie. stuck for long time at 1800MHz after some moderate load applied.
In colder ambient (~20C), even under full load, it maintained like 2400MHz.

But, I kind-of found the solution (or the real culprit...?): when force-cooling the underside of the laptop (I'm using 120mm PC fan on an upside-down laptop, since I use exclusively external displays anyway), it stayed at about 3500MHz under load, even in 25C+ ambient.
And the cores were near the 100C themselves all the time. On the contrary, in throttling situations like above, they were at ~50C, but not speeding up despite that.
So, I think that there is some sensor other than the CPU cores itself, probably near the bottom, that induces that heavy CPU throttling.

My conclusion: should be fixable via BIOS, and I strongly hope that someone capable of it notices it too.

edit: would be nice if someone can confirm my experiments with cooling the underside.

mazzz1y · 2021-08-05T15:47:46Z

@JMKS87

Developer from thermald project found that it related to TMEM sensor limit: intel/thermal_daemon#293 (comment)

So I think that you're right

mazzz1y · 2021-08-05T16:01:26Z

My conclusion: should be fixable via BIOS

the weird thing is that it works correctly on Windows

JMKS87 · 2021-08-07T15:17:27Z

Ah, right. So, if Windows is not doing anything magical (I don't think it is, it's just more popular, so it's diagnosed & fixed much faster), Linux should be able to do it too, via software.
Or the case may be a little "speculative" - Windows has some workaround for ignoring some sensor, but since the software is closed-source, we don't know about it. And Linux "is not doing it" since it is not in line with guidelines.

In fact, tinkering with thermald's source code could be in reach for some of us, and maybe it is enough.

igoropaniuk · 2021-08-10T00:00:36Z

@academo could you please share your lenovo_fix.conf you're currently using for your thinkpad ?

ftsogr · 2021-08-21T12:53:07Z

I mentioned my temporary workaround some months ago in dell forums too...

I am using debian bullseye without thermald installed.
After the boot, I am running the commands below one by one and with the same sequence:

sudo rmmod intel_rapl_msr
sudo rmmod processor_thermal_device
sudo rmmod processor_thermal_rapl
sudo rmmod intel_rapl_common
sudo rmmod intel_powerclamp

sudo modprobe intel_powerclamp
sudo modprobe intel_rapl_common
sudo modprobe processor_thermal_rapl
sudo modprobe processor_thermal_device
sudo modprobe intel_rapl_msr

I am using these commands in a systemd service that I enabled it and it is running on boot.

n0rad · 2021-08-21T16:55:44Z

thx @ftsogr

I just tested on my latitude 7420 with archlinux and indeed without thermald nor throttled and just reloading the modules in order, it looks better.
I'm not stuck anymore at 400Mhz on load and going up to 4Ghz on normal usage.
but when stressing cores, it all get quickly stuck up to 1800Mhz

ftsogr · 2021-08-22T19:23:03Z

I think that dell will take the issue more seriously if more people mention it in dell forums.

ywwg · 2021-08-25T18:30:12Z

UPDATE: in a lenovo if you use Fn+l or Fn+m or Fn+h you can change the CPU performance mode. This made my processor go from running in 10w to 20w but still not enough to make it to 44w so running the script still makes it go faster.

The fn keys work for me on a Lenovo Thinkpad X1G9, it changes the max wattage like this:
l: 7.5w
m: 15w
h: 64w

How did you find out about these fn keys?

update:
This is all pretty fascinating -- the thinkpad will also down-scale the performance setting if the connected power supply is < 64w. So if I connect a 45w supply, it will choose the "medium" value of 15w. This seems smart to me! (also too, if you go to battery mode, it'll drop to 15w).

My conclusion for this particular model is throttled is not needed, nor are any other of the workarounds / daemons / kernel options / commands. You just have to push fn-h after startup and check that /sys/devices/virtual/powercap/intel-rapl-mmio/intel-rapl-mmio:0/constraint_0_power_limit_uw has the correct value. (The other values seem to be correctly set to 64w)

(this reddit thread is correct, and also seems to suggest there is a lap detection system that can further limit the performance mode?? https://www.reddit.com/r/thinkpad/comments/i4x8i8/tip_for_x1c7_and_perhaps_other_recent_models/)

Using s-tui to monitor and stress
Laptop set to performance with fn+h
Thermold stopped, masked and uninstalled (you never know!)
Latest BIOS available installed

When using high CPU this happens (no fixes applied):

The laptop spikes up to 35w of power usage and after 1 or 2 seconds:
It goes down to 10w and will not go beyond that. 1Ghz speed.

if the static fix mentioned in the readme is applied:

The laptop spikes up to 35w of power usage and after 1 or 2 seconds:
It goes down to 10w and will not go beyond that. 1Ghz speed.
Static Fix applied
It goes up to 35w again for about 3 to 5 seconds (seems random). Full clock speed.
It goes down to 10w and will not go beyond that. 1Ghz speed.

When using throttled and performing a stress test, it behaves as it no fix was applied (no difference)

In practice:

throttled itself doesn't fix the throttling problem for me
The static fix does resolve the throttling for me but only for a short period of time (2-5 seconds).

My current solution?

Run the static fix in an infinite loop every 2 seconds. I added as a service for systemd. This is the script: https://gist.github.com/academo/30c781932b6b66adaacbc8932690f820

With this fix applies the laptop maintains 35w power consumption and the highest clock speed.

If any of you have a better solution or think what I am doing is dangerous for the CPU please let me know. I haven't found any other way to make this laptop work properly.

UPDATE:
Running:
cat /sys/devices/virtual/powercap/intel-rapl-mmio/intel-rapl-mmio:0/constraint_0_power_limit_uw

With fn+l: 5000000
with fn+m: 6000000
with fn+h: 10000000

With the static fix: 35000000 (I set this value, it makes sense).

is it the default performance mode on this laptop defaulting to 10w? That's really low when you look at the processor capacity. Can someone with the same model confirm?

I think that need to create separated issue for lenovo laptops because it's not related to throttling issue with dell

drvenabili · 2021-09-14T15:35:47Z

I am having just this issue with the 1165G7 in a lenovo thinkpad.

similar to what @dcplaut mentioned, if I run the static fix it "releases" the power, but quickly something sets it back to 10w.

What I ended up doing is a bash script that runs as a systemd service in an infinite loop every 5 seconds and set the values (the static fix commands) if is connected to AC only.

That fixes the problem for me but I can't stop thinking, what's exactly limiting the processor to 10W? Is it bad what I am doing? setting constantly a limit for 44w?

My computer runs very hot when I am doing heavy compilation things and I can see the temperature going in highs 90C degrees and thermo throttling (which is good at that temperature!)

Perhaps someone has some light in this issue?

UPDATE: in a lenovo if you use Fn+l or Fn+m or Fn+h you can change the CPU performance mode. This made my processor go from running in 10w to 20w but still not enough to make it to 44w so running the script still makes it go faster.

Hi @academo !

Any chance you could share the script, as well as your config file? I have a P14s Gen2 and I'm being limited quite a lot.

Additionally, what's the max frequency you get under a stress test? Mine does not go above 1.2 GHz under the s-tui stress test, despite temps being in the 50C range. I have speedstep disabled, if that helps.

Thanks

academo · 2021-09-16T07:51:33Z

@faustusdotbe the script is shared in my original message as a gist. Under a stress test I see all the cores going up 2.8Ghz and some boosting up beyond 3ghz.

Btw @whoenig created a new issue to follow up on the lenovos. let's move the conversation there. #265

errogaht · 2021-11-26T15:11:03Z

the same issue with i7-11850h but throttling going to 800MHz.

drvenabili · 2021-11-26T15:14:32Z

Hi @errogaht

If you have the thinkpad P14s please have a look here https://github.com/whoenig/thinkpad-p14s-gen2-ubuntu

@whoenig compiled a few tricks to get the P14s working quite well. It's been my daily driver for a few months now and I've not encountered issues.

Grtschnk · 2021-11-29T07:30:59Z

Same issue: Long time (+2s) Power throttling at 10-12W. It can boost but quickly goes down and stay around 1,800Mhz.
Latitude 7420, BIOS v1.22.2, Arch - up to date.
(and I've tried all the permutations of posted solutions)

Also experiencing the issue with mismatching MSR writes and reads.

Not sure where exactly the fix is to be found: throttled, thermald, kernel, intel, dell or throttled.. I'll probably give up for now and just hope it will be fixed one day (only blaming the big vendors here, not any of the open source projects ;) ).

Grtschnk · 2021-11-29T19:20:51Z

Wondering if this is related:
https://gist.github.com/Mnkai/5a8edd34bd949199224b33bd90b8c3d4
page 149 or search for PKG_PWR_LIM_LOCK https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/10th-gen-core-families-datasheet-vol-2-datasheet.pdf

Now, is the register read correctly at all or is it only read only? If it is read correctly wouldn't that mean that the limit does not apply at all? 0xffffffff is a big number

kreuzman · 2021-12-17T12:47:44Z

Thank @ftsogr I'm on Dell Latitude 5421 using using Debian Bullseye and loading/unloading of modules works for me. Like @n0rad when stressing cores to maximum frequency drops from Max Turbo to TDP frequency (in my case 2.5 GHz). I suppose this is expected as Turbo Boost is not designed to run for long time on all cores.

In my case I needed to load/unload one more module processor_thermal_device_pci_legacy because it is blocking to rmmod processor_thermal_device. In my case order of models reloading looks like this (if it help to anyone).

sudo rmmod intel_rapl_msr
sudo rmmod processor_thermal_device_pci_legacy
sudo rmmod processor_thermal_device
sudo rmmod processor_thermal_rapl
sudo rmmod intel_rapl_common
sudo rmmod intel_powerclamp

sudo modprobe intel_powerclamp
sudo modprobe intel_rapl_common
sudo modprobe processor_thermal_rapl
sudo modprobe processor_thermal_device
sudo modprobe processor_thermal_device_pci_legacy
sudo modprobe intel_rapl_msr

sebastianha · 2021-12-17T12:56:35Z

When you are doing this, do you stay stable for e.g. 10 minutes on 2.5GHz? At what temperatures?

kreuzman · 2021-12-17T14:59:42Z

@sebastianha When running stress test it's usually in Turbo Boost for couple of minutes with ~3GHz (all cores) frequency with temp. ~90 °C. Then it's throttled to 2.5GHz (all cores) and it's stable with temp. ~75°C. Then after while it goes to Turbo Boost again. You can see running stress test on pictures.

sebastianha · 2021-12-17T15:02:37Z

Sounds correct, thanks! Unfortunately this does not work on my 7320.

sebastianha · 2022-01-19T16:24:40Z

[D] TEMPERATURE_TARGET - write 0x5 - read 0x0 - match ERR
[D] CONFIG_TDP_CONTROL - write 0x2 - read 0x2 - match OK
[D] MSR PACKAGE_POWER_LIMIT - write 0x42816000dd8160 - read 0x42816000dd8160 - match OK
[D] MCHBAR PACKAGE_POWER_LIMIT - write 0x42816000dd8160 - read 0xffffffffffffffff - match ERR

Might it be possible that writing to the MSRs is locked at all (by EFI/BIOS?)? It could be by accident that the second and third are ok as it had just the same value before. At least for me CONFIG_TDP_CONTROL is already set to 0x2 after boot.

sebastianha · 2022-03-10T12:56:33Z

On thermald there just was a breakthrough for this problem: intel/thermal_daemon#341 (comment)

Now the CPU runs at full power for 60s then throttles down (it does the same on Windows). Next steps are trying to remove this limitation, on Windows this is possible by locking MMIO via Throttlestop.

AdamantGarth · 2022-03-10T13:00:40Z

It's weird, but it seems like the problem is fixed for me (on 5420) even without the patch. Compiling the kernel with it right now and the CPU is at 2.4GHz, 70°C for 25 minutes already.

~~Edit: Nope, 50 minutes in - locked at 1.5 GHz and 40°C :(~~ - Sorry, it was because the kernel just compiled 😅

I don't see this behaviour on my 7320. I've running this patch from morning, few minutes ago I've started system update (I have gentoo so compiling everything) and it's running fine - temperature near to 98°C all the time, frequency at start below 4GHz, after several minutes (5+) it downscales to something like 3,2GHz (temperature still on ~98°C) so I believe that it's totally OK for 3GHz base frequency CPU.

sebastianha · 2022-03-10T13:29:15Z

There might be a difference as I am currently running on "optimized" BIOS settings. There is also "Ultraperformance" available but I currently have no time for intensive testing.

On 7320 the patch definitely fixed it. I have read in other tickets that this was not a problem on 5420 and others notebooks, that was also the reason I opened a ticket exactly for the 7320.

spamik · 2022-03-10T13:33:53Z

Well, it may be this settings. I have ultra performance configured since I start solving this issue. I also want to try to set it back to optimized as now I can hear that this laptop is quite silent even running with fan on 100%. And with ultra performance it makes almost same noise under heavy load as with regular using so I want to keep it more silent on normal using. I'll let you know when I will have mood for reboot and reconfiguring BIOS it it's start throttling earlier.

lakotamm · 2022-08-03T14:43:31Z

Would anyone with a Tigerlake CPU be able to run this command?
sudo setpci -s 0:0.0 48.l

It should report the address of the MCHBAR register. As @sameer reported it seems like writes into the register fail. On Alder Lake we are experiencing the same issue and we found that the address has changed sometimes after the 10th gen and changing it to the correct one fixes the issue.

Thanks! So the address is the same as for AlderLake. No wonder it does not work.

Could you please report cpuinfo?

cat /proc/cpuinfo

I enabled Tigerlake support in this commit and it would be great if anoyone could test it.
