[TRACKING] Linux battery life tuning

pierce · June 3, 2024, 1:29am

Indeed, that was it. Thanks!

Mario_Limonciello · June 3, 2024, 2:05am

Great! I’ve added such a check to the script now too.

fbl · June 4, 2024, 10:35pm

The issue might not be directly related to docking afterall. In the last few days I have specifically paid attention to when the issue appears. I have written a small script which checks for s0ix residency (/sys/kenrel/debug/amd_pmc/s0ix_stats) after every suspend, and I was able to trigger the issue after only a few suspends without attaching or detaching anything in between.

Is there anything I can do to analyze this behavior further?

fbl · June 4, 2024, 11:16pm

Is it possible that this is somehow related to [TRACKING] Framework AMD Ryzen 7040 Series lid wakeup behavior feedback?

Observations:

Hardware sleep state residency is way smaller if keys are pressed during the 10 second sleep duration of the amd_s2idle.py script (laptop does not wake from sleep due to kernel workaround for spurious IRQs)
Without any key presses during suspend, the laptop suspends reliably
Randomly pressing keys during suspend makes it more likely for the issue to appear
Pressing keys during regular suspend and waking the laptop shortly afterwards sometimes results in weird behavior: Sometimes everything works, sometimes the KDE Plasma Wayland session crashes (back to display manager), and sometimes the whole system crashes (Black Screen → Framework Logo → Bootloader, journald stops after entering s2idle)

JL_Framework · August 29, 2024, 12:59am

Does anyone know whether recent-ish kernels - the 6 series - help with battery life? Thanks.

David_Markey · September 1, 2024, 4:41pm

Seems this patch has landed in 6.10.7 as it no longer applies… Is that correct @Mario_Limonciello?

Mario_Limonciello · September 1, 2024, 5:54pm

Which patch?

Be_Far · September 2, 2024, 1:03am

It’s about the same feeling to me. The biggest indicators of battery life are going to be hardware and your tlp profile (disabling turbo boost on bat and throttling to 25% instead of the default 30% on bat made a huge difference for me recently).

Be_Far · October 4, 2024, 5:25am

New tip I’ve discovered, something I installed enabled avahi-daemon on my laptop (upon further research it may have been CUPS, even though I don’t have cups-browsed installed). Setting it and its socket to disabled on battery power dropped my idle power consumption on an 11th gen i5 (original panel, original speakers) to 5W. Will update if this causes any functionality issues.

h/t sinatosk for teaching me about more systemd options:

sudo systemctl disable --now avahi-daemon.service avahi-daemon.socket

sinatosk · October 4, 2024, 10:27am

Incase you didn’t know, you can do that in one line

sudo systemctl disable --now avahi-daemon.service avahi-daemon.socket

the “–now” option will stop the services/sockets if they are running.

if you use “–now” with enable then it will start the sercices/sockets

Stebalien · October 4, 2024, 1:26pm

I found adding rcu_nocbs=all rcutree.enable_rcu_lazy=1 to my kernel cmdline to be pretty helpful in terms of power savings, although upgraded screen kind if wiped out those power savings…

See https://discourse.ubuntu.com/t/fine-tuning-the-ubuntu-24-04-kernel-for-low-latency-throughput-and-power-efficiency/44834

I also have psi=0 because I have more memory than sense (you probably shouldn’t do this, but PSI accounting was showing up in powertop and I didn’t really need it).

JL_Framework · October 8, 2024, 12:52am

Hello there. @Mario_Limonciello asked you, ‘Which patch?’ I too would like an answer to that question. That is: just what problem, to do with battery life, does something within the 6.10.7 kernel solve, please? Thanks.

EDIT: Using the (paid) program called ‘UKUU’, I installed a 6.10.10 kernel on Linux Mint, on my FW-13, and the machine would not boot; It didn’t even make it past the screen showing the Framework logo. Still, 6.8 is the highest kernel that Mint supports officially currently. (Mint has abandoned its ‘Edge’ edition, but in compensation now the normal versions of Mint use slightly newer kernels than they used to.) I tried kernel 6.10.7 - which is the first kernel to have ‘the patch’ at issue - and that one did not boot either.

David_Markey · October 8, 2024, 10:55am

Sorry, I was on the wrong thread with “what patch”… I meant the better power consumption for video decoding witch was merged a while ago.

JL_Framework · October 8, 2024, 12:12pm

Ah. Thanks for the clarification. But: do you know the kernel in which the (or some?) of the power-saving stuff discussed in this thread arrived?

Jacob_Spiteri · October 9, 2024, 10:19pm

Recieved my 7640u fw13 October batch today. Running Bazzite and ran the amd_s2idle.py script and recieved two errors “AMDGPU ppfeaturemask overridden to 0xffffffff” and “Kernel is tainted 12289”. Is this anything to be worried about (affect battery life) or should i just ignore them? If so any suggestions on how to fix these errors.

Firestorm980 · October 10, 2024, 12:17am

Sounds like a good question for @Jorge_Castro, as he’d have a better idea of it on bazzite.

mikeymop · October 13, 2024, 7:08pm

I took another shot at gleaning out more battery life from a 7840u board.
I noticed with lspci -vv that ASPM is reported as disabled for all of the reported devices.

I used powertop --auto-tune and pcie_aspm=force and did experience better idle consumption ~3.25w and slightly better suspend power consumption 10% over 10 hours.

I don’t think the intention is to need to force aspm so I suspect the firmware is reporting the hardware incapable for a good reason.

However amd/drm appeared to crash when I started using the computer the next day and I let the screen blank when idle.

[ 7139.117896] amdgpu 0000:c1:00.0: [drm] *ERROR* dc_dmub_srv_log_diagnostic_data: DMCUB error - collecting diagnostic data
[ 7139.218469] usb 1-4: reset full-speed USB device number 2 using xhci_hcd

[ 7139.693252] amdgpu 0000:c1:00.0: [drm] *ERROR* dc_dmub_srv_log_diagnostic_data: DMCUB error - collecting diagnostic data

This triggers the 1fps framebuffer so I had to reboot.

At the time I was charging the computer with the cable in the back left slot.

Is it possible the firmware is not allowing aspm because the port is awake from charging? Could be causing the crash? Or are the usb errors, aspm, and the graphics driver unrelated?

Is anyone else successful with aspm on the 7840u boards?
Are the 7840u boards expected to be capable of aspm on 6.10 kernels?

JL_Framework · October 17, 2024, 12:20am

Heads up: I tried nvme.noacpi=1 on my F-13 AMD, running Linux Mint Cinnamon with a 6.8 kernel and, for the first time, the machine would not resume from suspend.

Mario_Limonciello · October 17, 2024, 3:50pm

Don’t use this. It breaks AMD suspend.

JL_Framework · October 18, 2024, 10:18pm

Thanks Limonciello.

It is hard to tune battery life under Linux when the computer does not even report its own battery status reliably (or, rather, draws power from the battery when it should not).
