Homebrew Discussion Team-Xecuter gives hint to Battery Desync issue

[PRAGMA]

"If we had to give the community a hint as to where to start looking into this "battery desync" problem we'd suggest looking into how the Fuel Gauge IC (MAX17050, I2C1 addr 36) is being used by Nintendo's OS and by Linux."

This seriously isn't a hint as it's known since day 1 lol

Oh yeah? Show us please. No one gives a fuck if someone knew it. Clearly it wasnt being posted anywhere, but now it is.

pretty sure its a hint on how to fix it and not a hint that it exists

I've personally looked at the Issue just a few days after shofel release, wanna show my search requests for the MX chipset?

Just dropped it because of lack of time

It just gives us a IC name as well as a I2C addr, both are well known even before homebrew existed on the switch in the form we know it

"Look and compare", I mean, thats common sense among coders. I mean come on..

Edit: I actually looked it up, while I have this exact chipset for some reason in my search history related to the Issues (probably looked up most of the maxim chipsets ) , I only find information to MAX77620, because those header files were copied, for the Power Management IC.

Edit2: https://github.com/fail0verflow/switch-linux/issues/6

So it was actually know. I really should stop now. I tricked myself

I didn't find any results to the actual fuel gauge used

Now, this gets interesting

Note: This probably isn't it, just funny in function https://github.com/torvalds/linux/blob/master/drivers/power/supply/max17042_battery.c#L717
(Tho it's a different file, too much beer, sry )

It is actually the driver for the batt as said by tardyp
"/* Write dQ_acc to 200% of Capacity and dP_acc to 200% */"

This probably isn't related, but given it drops at 50%, I already had the thought that maybe the capacity is written as double the amount (but since we can discharge it to low% if there isn't a load, can't really confirm it, but given horizon shuts off, it could just think there is no gas left, but the other way around could be valid too. According to the issue a different module gets loaded so it's maybe reading a 100% but expecting a 200% value, since the other module doesn't initialize the battery properly. Or it can be something completely different, it was late at night and I didn't skip through too much code)

So that actually looks suspicous, given I already had the idea of it

Would you be able to fix this issue?

I shouldn't look at code with that much beer, its the wrong file

Double wrong makes right!

But my oberverations are still the same

Looks like it was posted on GitHub.

Calm down Mr internet tough guy...

m4xw was right, it was here since day 1. (Calm your tits)

Here since day 1?
Well, darn, I feel like someone should've fixed it by now, considering how long it has been since that issue was posted.

Ikr, it seems very difficult.

 

[natinusala]

Because nobody gives a shit because Linux is useless for now ?

I personally want it fixed for lakka only.

>lakka and hw acceleration

coming from you that is weird to read...what about lakka for emulation?

The sound doesn't work and wifi sucks on it, most cores don't even boot. Would hardly consider it usable for everyday usage.

 

[natinusala]

Next Lakka update will at least contain Bluetooth audio and full speed Wi-Fi / Bluetooth. Maybe not soon (Whiterun is beautiful in VR) though.

edit : + i'm working on Moonlight so eh

Would that also include a battery fix please?

 

[DiJornios]

Smh if you guys want a battery fix so bad then why don't you figure it out?
