Ryzen 5x GPU always in D0 state

us flag

Ubuntu 22.04,
linux-oem-22.04b (kernel 6.0, same behavior on 5.15)
asus vivobook 15x

cat /sys/class/drm/card0/device/power_state
D0

the state is D0 even when only one terminal is running (should be D1-D2 or D3 in idle)

cat /sys/kernel/debug/dri/0/amdgpu_pm_info

shows temp 44-45C

laptop's rear is always hot

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
amd-pstate

Power consumption in idle ~ 5-6w.

What can be done ?

EDIT:

amdgpu: dpm has been disabled

dmesg shows that dynamic power management is disabled for gpu

the cause is still not known

Didn't find the reason, but removing built-in gnome power-profiles and installing tlp did the job better:

sudo systemctl mask power-profiles-daemon.service
sudo apt purge --auto-remove power-profiles-daemon

tlp:

sudo apt install tlp
sudo systemctl enable tlp.service

reboot

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
