Hi,

I found your project when looking around for options to tweak power profiles so that I can get more battery life.

From a previous ticket I saw you guiding the reporter to provide you the DSDT.dsl file ( #13 ) so I went ahead and already uploaded that.

The current code compiles but the module refuses to load on 6.1, 6.2 and 6.3 the messages are identical.

sudo make reloadmodule

When trying to load with forcereload I get the following:

As requested in the other ticket, please find attached the DSDT.dsl file:

DSDT_16ARHA7.zip

I took a look around and found the region with most of the fields is at: 0xFE0B0400

OperationRegion (ERAX, SystemMemory, 0xFE0B0400, 0xFF)
                    Field (ERAX, ByteAcc, Lock, Preserve)

The next best list of fields was a bit further down:

                    Scope (\)
                    {
                        OperationRegion (LFCN, SystemMemory, 0x92DD2298, 0x0377)
                        Field (LFCN, AnyAcc, Lock, Preserve)

I also had a look at your code but couldn't figure out how you know what to map.

Thank you for this project. Let me know if any further information is needed.

I used the offset from your file (0xFE0B0400) and updated the code to use this offset for your BIOS. Let's try it with it.

Please pull new version, build with make and load with make forcereloadmodulereadonly. Then give the output from dmesg (should be outputted after loading) and (if possible) from cat /sys/kernel/debug/legion/fancurve. Also output cat /sys/kernel/debug/legion/ecmemory | hexdump -C after you changed the powermode with Fn+Q (three times).

What exactly do mean by "tweak power profiles so that I can get more battery life"? Most of the power saving should be possible without this module.

  • CPU: use correct driver, select correct governor, disable boost if you want, throttle max frequency if you want
  • GPU: use iGPU in CPU instead of discrete GPU such that GPU can power down; This can be done in hybrid mode for a NVIDIA GPU. I guess you have a AMD GPU, so this might be similar.
  • Screen: reduce frame rate, reduce brightness
  • WiFi: power save mode

Thanks for the changes and the detailed response, I really appreciate it. Looks like its working.
The test confirms that I can alter the fan curve as suggested in the test pack as well.

Here is what I ran and observed in detail on 6.2-rc8:

The test confirms that I can alter the fancurves as suggested in the test pack as well.

For your other suggestions, I'm currently on a journey to address compatibility issues one by one, so far I managed to:

  • CPU: I've not been aware that I can select a driver, I'll research what to do on 6800H -(edit) I am using amd-pstate
  • GPU: I had some rendering issues that I addressed using a custom patch based on a suggestion from AMD, didn't even get to finding out why vgaswitcheroo isn't working yet. It's been surprisingly difficult to get the dGPU to turn off, I mostly use the iGPU as it's perfect for most my work needs.
  • Screen: the screen is reporting 60Hz, but that might not be true, not sure how to test that
  • Wifi: I switched the card for a Intel Corp. AX210 since the built in card was bad. I didn't know one can trigger power save mode on the card. Will also investigate this.

Hmm. I am a bit surprised that it works.

Could you please make the following tests and report back:

  • Quick Test: Read Sensor Values from Hardware (for details see README): Are the RPM and temperature values plausible and increase/decrease?
  • Change the fancurve. Does the fans react according to the settings of the fan curve and attain approximately the set values.
  • Test according to "Change power mode from software" from README. Does powerprofilesctl list and powerprofilesctl set balanced and powerprofilesctl set performance work? Does the LED on the laptop change accordingly?
  • Does disabling mini fancurve works described in "Enable or disable the mini fan curve"
  • Does "Lock and Unlock the Fan Controller and Fan Speed" works?
