Commen= t # 5 on bug 11148= 2 from Robert 
One additional observation I made yesterday: If I stop sddm/KD=
E via "systemctl
stop sddm" the frequency has changed after I'm back in console:

"""
cat /sys/class/drm/card0/device/pp_dpm_mclk
0: 100Mhz=20
1: 500Mhz *
2: 625Mhz=20
3: 875Mhz=20
"""

At this point I'm also able to even go to "100MHz" and power cons=
umption goes
down at least to 13W. If I run "systemctl start sddm" again I onl=
y the the KDE
Plasma start logo and that's it. Going back to console and stop sddm agin
frequency is again at "875MHz" and can't be changed anymore. In t=
his case
you've to reboot.

But I guess without some developer guidance/hints there isn't much I can do
anymore.
