Tool for power mode and custom fan control #8

johnfanv2 · 2023-01-30T11:45:39Z

I created a tool for custom fan curves for Lenovo Legion 5, Legion 7 etc. It is called LenovoLegionLinux and is on github https://github.com/johnfanv2/LenovoLegionLinux

I guess it also works for the 15ARH05 series because it works for the 15ARH05A series. If you want, you could try it according to the README and let me now if it works or if something has to be fixed.

Awesome!
I was recently looking for such tool for my Legion 5-17ACH6 which has horrible high pitched fan noise at certain RPM and it drives me crazy.
I'll test it out this week and see what does or doesn't work.
Thank you!

Edit:
Legion 5-15ACH6, Legion 5P-6ACH6, Legion 5-17ACH6 are using the same BIOS so they should all be compatible.

I would highly recommend you to avoid using Lenovo's name, since it's copyrighted. I have seen DMCA takedowns even from Github for using their name in a open source software name. Hope that helps.

@johnfanv2 Looks like it works fine on my 5-17ACH6. I didn't exactly test every possible option, but it looks like everything is working. Installation went smooth on kernel 6.0.9
It seems that minifancurve was causing me headaches and disabling it made using the laptop 10x better.
Thank you so much!

johnfanv2 · 2023-02-03T19:24:34Z

@rozwell Thanks for the test and the information. Yes, mini fancurve is enabled by default in the firmware and you can disable it if you do not want it. Can you tell me your BIOS version sudo dmidecode -t bios.
@antony-jr Thank's a lot for the information. I guess, I will have to rename it.

pm4rcin · 2023-03-06T20:38:58Z

@johnfanv2 is is possible to integrate your project to powerprofilesctl in the future? Because for me the output is:

❯ powerprofilesctl list
* balanced:
    Driver:     placeholder

  power-saver:
    Driver:     placeholder

johnfanv2 · 2023-03-06T20:42:47Z

Hmm. It should work with it. Have you loaded the kernel module? Does the other stuff work? What is the output of sudo dmesg after loading it. What is the output of sudo cat /sys/kernel/debug/legion/fancurve?

johnfanv2 · 2023-03-09T21:49:09Z

You can check it in the README of the tool it should be

# List all profiles (power-saver = quiet= blue)
powerprofilesctl list

#   performance:
#     Driver:     platform_profile
#     Degraded:   no

#   balanced:
#     Driver:     platform_profile

# * power-saver:
#     Driver:     platform_profile

@pm4rcin If you can give me the requested output I could try to diagnose your problem.

@johnfanv2 I'm on Arch(btw) with kernel 6.2.2

johnfanv2 · 2023-03-11T23:39:59Z

Everthing looks good! The driver creates the files "/sys/firmware/acpi/platform_profile" and "/sys/firmware/acpi/platform_profile_choices". Check if they exists and contain the useful values.

cat /sys/firmware/acpi/platform_profile
# quiet

cat /sys/firmware/acpi/platform_profile_choices 
#quiet balanced performance

If powerprofilesctl list still gives wrong values, maybe you have to configure the power-profiles-daemon somehow to pick up these values.

pm4rcin · 2023-03-12T10:28:41Z

So they exist and have useful values like you but when I do echo quiet it changes the value but doesn't change the led color of power button. So I'm not sure if it does anything at all. powerprofilesctl list still gives wrong values.

pm4rcin · 2023-04-02T18:50:01Z

@johnfanv2 thanks to your new instructions on RE I have dumped the EC values when I change from various power modes with fn+Q. Tell me if you need something more. These are files from dumping cat /sys/kernel/debug/legion/ecmemory | hexdump -C
start_normal.log
silent_to_start.log
perf_to_silent.log
normal_to_perf.log

johnfanv2 · 2023-04-03T06:37:43Z

@pm4rcin sorry, for the later reply. I did not see this thread. I guess everything works for you except this power profiles thing.
Could you try reading/writing directly the powermode?

# display power mode (try switching manually)
cat /sys/module/legion_laptop/drivers/platform\:legion/PNP0C09\:00/powermode

# set a power mode (balanced)
echo 0 > /sys/module/legion_laptop/drivers/platform\:legion/PNP0C09\:00/powermode

pm4rcin · 2023-04-03T08:12:12Z

Exactly. Everything but power profiles. I can change the value of powermode with your command but the diode stays the same color. Only fn+Q works.

johnfanv2 · 2023-04-05T14:04:08Z

Interestingly. I can change the power mode with another adsress in the embedded controller. I will build a version for you withe the change. If you change the power mode with Fn + Q, does the output of the following changes?

# display power mode (try switching manually)
cat /sys/module/legion_laptop/drivers/platform\:legion/PNP0C09\:00/powermode

pm4rcin · 2023-04-05T14:18:36Z

If you change the power mode with Fn + Q, does the output of the following changes?

No

pm4rcin · 2023-04-06T10:22:11Z

So I've done some more tests and this time restarted power-profiles-daemon. Sorry for So now I have correct output

❯ powerprofilesctl
  performance:
    Driver:     platform_profile
    Degraded:   no

* balanced:
    Driver:     platform_profile

  power-saver:
    Driver:     platform_profile

And also the powermode in sysfs is changing when powerprofilesctl is used. But still fn+Q doesn't change values there nor powerprofilesctl change the LED color.

johnfanv2 · 2023-04-07T00:48:25Z

@pm4rcin I guess we have to find the memory address for you model for the power mode. Can you verify that the byte at offset 0x1D that I marked with HH in the next line below corresponds to the power mode. Toggle the power mode with Fn + Q and observer the value with cat /sys/kernel/debug/legion/ecmemory | hexdump -C. Does it change when the mode changes? Does it attain the values 02 (quiet=blue), 00 (balanced=white), and 01 (performance=red)?

00000000  00 01 00 00 00 00 00 00  00 00 10 00 00 25 19 00  |.............%..|

00000000  00 00 00 00 00 00 00 00  00 00 00 00 00 HH 00 00

Did you observe any other bytes that attain these values at other offsets?

pm4rcin · 2023-04-07T10:08:17Z

So that HH changes exactly as you've said. I have created diff of 3 files with command diff3 new_balanced new_perf new_quiet > new.diff. I can't see that other values changes as in the place you mentioned. Only place the 01, 02 and 00 but in the wrong order is in 20,30c.

Hmm. Can you switch powermode with Fn + Q instead of powerprofilesctl?

pm4rcin · 2023-04-07T14:17:29Z

EDIT: Oh looks like powerprofilesctl switches diode but not power mode.

So if you press Fn + Q the mode displayed via powerprofilesctl list updates correctly? But the LED does not change if you change the power mode with powerprofilesctl set?

pm4rcin · 2023-04-07T14:37:55Z

Yes
It looks like everything works now. Maybe I've had an old data copied in primary selection. Sorry for my dumbness.

johnfanv2 · 2023-04-07T14:40:37Z

Great! Thanks for the detailed troubleshooting. So can you confirm that everything is working as described below?

if you switch power mode with Fn + Q this changes the output of powerprofilesctl list correctly?
if you switch powermode with powerprofilesctl set this changes the LED color and the fan curve reported by sudo cat /sys/kernel/debug/legion/fancurve?

pm4rcin · 2023-04-07T15:09:40Z

Yes
Yes
If I'm not mistaken there's only 1 thing left that requires ACPI calls rather than some sysfs or similiar interface. It's the rapid charge. I use the https://github.com/0xless/battmngr which utilizes information from wiki. Make sure to read the note because I'm not sure if it is kernel's responsibility or userspace tool. And what if someone wants to rapid charge but only to the battery conservation level and then turn rapid charge off?

PS. Regarding point 3 I'm not saying you have to implement that but it's probably the only thing for ultimate all in one Legion experience.
PS2. On Readme of your project the Legion 5-15ARH05 has listed BIOS version FSCN14WW but I think it's a mistake since I could only find EUCN BIOS for that model. If you think it's right than prove me wrong. From my research FSCN14WW is for 5-15ARH05H.

johnfanv2 · 2023-04-08T17:02:03Z

@pm4rcin Thanks for the tip for the README. I guess the H is missing.

I also created an new version with rapid charge support. Please try the new feature for enabling/disabling rapid charge. Please make sure that rapid charge is really enabled/disabled as configured and shown, i.e. that it charges faster/slower. In particular, if battery conservation is enabled, rapid charging should automatically be disabled by the python user space tool. Maybe this can be checked by the estimated charging time.

According to antony-jr/lenovo-legion5-15arh05-scripts#8 (comment)

pm4rcin · 2023-04-08T21:48:36Z

Happy to say that everything works as expected. I have checked battery charging with bottom and rapid charge works and reports higher power (more than 2x of normal charging). When you click battery conservation or rapid charge the former disables the latter and vice versa.

Regarding the change in README there's one more thing. There's no such model as 5-15ARH05A. That should be changed to 5-15ARH05 which is my model with updated description of working features.

The things left for my laptop are:

Touchpad enable/disable is grey for me. I don't remember how it could be switched with sysfs or smth to check if it's your GUI not working properly or something on my side. I remember that I was able to switch that when I used KDE.
Set speed to maximum fan speed is also grey for me. Any hints? Should it even be working on my laptop at all?

johnfanv2 · 2023-04-10T21:54:16Z

Thanks for the feedback. Someone told me that one his 15ARH05A it works. I have found some hints that these exists (https://www.reddit.com/r/Lenovo/comments/10hnjig/factory_reset_my_legion_5_15arh05a_advice/). In any case, the BIOS is what counts.

Touchpad: This is provided by the kernel module ideapad if available.
Maximum Fan Speed/Dust cleaner: This is not implemented yet fully, hence disabled :)

The following features might be missing and might be implemented in the future:

toggling gsync
toggling internal GPU
toggling overdrive
toggling touchpad (with another method)
setting to max fan speed (with another method)
turn on/off keyboard backlight: do you have the white backlight?
Which of these features work on your device in Windows with Vantage or Lenovo Legion Toolkit?

pm4rcin · 2023-04-11T10:51:03Z

I don't use Windows so can't tell what works and what doesn't there.
Kde uses libinput for touchpad and it works great there.
My laptop doesn't have gsync/freesync so can't test.
iGPU/overdrive/fan max speed see point 1
I have white keyboard backlight and I'm able to toggle it with writing 0 or 1 to /sys/class/leds/platform::kbd_backlight/brightness

johnfanv2 · 2023-04-12T18:54:29Z

ok
I guess it is disabled somehow in software with libinput. This driver tries to do in "in hardware"
ok
Not sure what you mean with the listed features. Are these the functions you have? I created a new version with new features - still experimential. You can test them by writing and reading to files in ls /sys/module/legion_laptop/drivers/platform\:legion/PNP0C09\:00/. Still experimental, so it also displays features that you do not have. In that case it will return an error when trying to access.

cpu_shortterm_powerlimit
cpu_longterm_powerlimit
gpu_ppab_powerlimit
gpu_ctgp_powerlimit
gpu_ctgp2_powerlimit (readonly)
isacfitforoc (read only - 1 if high power charger is connected)
rapidcharge
cpumaxfrequency (readonly),
gsync
overdrive
powerchargemode,
fan_fullspeed (only works in custom power mode mode probably not available on your model),
touchpad (lock touchpad)
winkey (enable/disable winkey)
and more

I have created a new version that also creates platform::kbd_backlight. Is this file from the legion driver or from ideapad? you can check with ls -lah /sys/class/leds/platform::kbd_backlight. If it contains PNP0C09:00, then it is from legion driver. Do you have the light that can be toggled by Fn + Space into the modes off, medium, full? Or just on/off?

pm4rcin · 2023-04-12T20:22:13Z

Switching touchpad by writing to PNP0C09:00 below works fine.

It's from ideapad driver. I have fn + Space with modes off, medium and full. But in ideapad driver there's only off or full.
