AMD Linux Graphics Driver To Switch To More Aggressive Power Heuristics By Default
AMD Linux Graphics Driver To Switch To More Aggressive Power Heuristics By Default
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.
3I don't recall how to check my currently active power profile
5cat `find /sys -name pp_power_profile_mode`4Why doesn't it search /sys/class/drm? Doesn't follow symlinks?

I believe it's
cat /sys/class/drm/card0/device/pp_power_profile_mode.There's also the
power_dpm_force_performance_level.3Was card1 for some reason despite not having a card0

Anyone know how this will affect systems with two GPUs (such as the Framework laptop with the GPU module)?
1Hype!
3Cool. I hope the next LTS will include this.
