From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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.

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

[–] kbal@fedia.io 10 points 1 week ago (1 children)

cat `find /sys -name pp_power_profile_mode`

[–] ryannathans@aussie.zone 3 points 1 week ago (1 children)

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

[–] kbal@fedia.io 2 points 1 week ago (1 children)

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

[–] ryannathans@aussie.zone 2 points 1 week ago

I feel like find is needlessly convoluted

[–] mouse@midwest.social 7 points 1 week ago (1 children)

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 1 points 5 days ago

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

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 9 points 1 week ago (2 children)

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

[–] petey@aussie.zone 2 points 1 week ago

Ah right, thank you, I missed that somehow

[–] possiblylinux127@lemmy.zip 0 points 1 week ago (1 children)

Some laptops have dedicated GPUs.

[–] DaPorkchop_@lemmy.ml 5 points 1 week ago

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

[–] poinck@lemm.ee 4 points 1 week ago (1 children)

Cool. I hope the next LTS will include this.

[–] possiblylinux127@lemmy.zip 1 points 1 week ago (1 children)

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

[–] poinck@lemm.ee 1 points 1 week ago

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.
