The many hardware monitoring (HWMON) subsystem updates were merged today for Linux 6.19 that is predominantly around delivering new hardware support.

There are several new HWMON drivers with Linux 6.19 including the Apple Silicon SMC, TSC1641 I2C power monitor, MPS MP9945, MAX17616, and MP2925 and MP2929. Of those the Apple Silicon SMC is quite notable.

Nice. The slow driver upstreaming is what I hate most about Valve's open source efforts.

They aren't even slow, to be honest. It's like 2 guys at Valve kicking this stuff out, and if it was standard practice for the manufacturers to divulge the registers and such for their products there would a minimal amount of trial and error and getting things to work well enough to be included directly in the kernel.

When can we expect it to hit SteamOS stable? Just checked my Deck and it's still on 6.11.

[–] cm0002@suppo.fi 6 points 6 days ago

It'll probably be 6.18 that goes into stable since 6.18 was just announced to be the next LTS kernel

I feel like shit, so I'm just going to moan on something tangentially related.

Everything has fucking temperature monitoring, jack shit has stuff to do anything about it, like fan management. My shit's overheating when I'm playing fallout 3 and fucking balatro, on a "gaming laptop" from 2017

I just got GPU temp monitoring working on my old dell laptop. "Heat management" for the GPU is pretty much just an extra chunk of steel tacked onto the heat pipe halfway between the CPU and its radiator, so GPU temps are always in the red.

I might as well just turn off monitoring and remain ignorant 🤷
