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 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.
It specifically says the change only applies to dedicated GPUs, not integrated ones.
Ah right, thank you, I missed that somehow
Some laptops have dedicated GPUs.
Okay, but the commenter said “my laptop with jts integrated GPU”. Obviously, laptops with a dedicated AMD GPU would be affected by this change.
I don’t recall how to check my currently active power profile
cat `find /sys -name pp_power_profile_mode`Why doesn’t it search /sys/class/drm? Doesn’t follow symlinks?
It’s
find -Lif you want it to follow symlinks.I feel like find is needlessly convoluted
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. 🤷
I have once seen it be card3 too, also despite not having any other gpus
Cool. I hope the next LTS will include this.
Which distro? Either way it is probably going to be at least a few years
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.
Hype!
I’d prefer a script that can change the profile, execute the game, then change the profile back.
