AMD Linux Graphics Driver To Switch To More Aggressive Power Heuristics By Default (www.phoronix.com)

A change queued up last week by AMDGPU driver maintainer Alex Deucher will now default to the fullscreen 3D workload profile for discrete GPUs. AMD APUs with integrated graphics will continue to use the default “bootup” power profile but discrete graphics cards will be running in the “fullscreen 3D” power profile by default.

Cool. I hope the next LTS will include this.

Which distro? Either way it is probably going to be at least a few years

poinck@lemm.ee on 19 Oct 07:20 collapse

No distro. I mean the next LTS version of the kernel. On Gentoo I can choose my kernel version, but it general I like to be on the stable LTS. But recently I needed to choose a more recent version for better compatibility of the amdgpu driver for the one game I am playing.

I don’t recall how to check my currently active power profile

mouse@midwest.social on 17 Oct 2024 13:57 next collapse

I believe it’s cat /sys/class/drm/card0/device/pp_power_profile_mode.

There’s also the power_dpm_force_performance_level.

Was card1 for some reason despite not having a card0

Cheers

I just checked myself and it’s card1 too, now I am curious why it’s not card0. 🤷

ryannathans@aussie.zone on 21 Oct 22:11 collapse

I have once seen it be card3 too, also despite not having any other gpus

kbal@fedia.io on 17 Oct 2024 14:23 collapse

cat `find /sys -name pp_power_profile_mode`

ryannathans@aussie.zone on 18 Oct 2024 00:27 collapse

Why doesn’t it search /sys/class/drm? Doesn’t follow symlinks?

kbal@fedia.io on 18 Oct 2024 11:53 collapse

It's find -L if you want it to follow symlinks.

ryannathans@aussie.zone on 18 Oct 22:12 collapse

I feel like find is needlessly convoluted

Hype!

I wonder how much this will affect the power usage during boot on my laptop with its integrated AMDGPU. Granted, boot time is fairly short so hopefully this won’t really matter.

DaPorkchop_@lemmy.ml on 18 Oct 2024 15:46 collapse

It specifically says the change only applies to dedicated GPUs, not integrated ones.

possiblylinux127@lemmy.zip on 18 Oct 23:32 next collapse

Some laptops have dedicated GPUs.

DaPorkchop_@lemmy.ml on 19 Oct 06:33 collapse

Okay, but the commenter said “my laptop with jts integrated GPU”. Obviously, laptops with a dedicated AMD GPU would be affected by this change.

Ah right, thank you, I missed that somehow
