dmesg

I use following setup:
1) HP EliteBook 745 G5 with Ryzen 5 PRO 2500U
2) Docking station HP HSTNN-I11X
3) Monitor BenQ GW2260 (HDMI and no DisplayPort)
4) openSUSE Tumbleweed=20
5) Self compiled kernel 4.20-rc3 from amd-staging-drm-next with patches:
drm/amd/display: Include names of all PP clock types
x86/MCE/AMD: Fix the thresholding machinery initialization order

My problem is that I can't use notebook's HDMI port (visible as DisplayPort=
-0)
after using DisplayPort output of docking station. HDMI detects monitor &am=
p; gets
EDID but xrandr doesn't list any modes.


After booting without docking station & connecting monitor using HDMI p=
ort:

After connecting monitor using HDMI port:
xrandr: Output DisplayPort-0 is not disconnected but has no modes
(...)
DisplayPort-0 connected (normal left inverted right x axis y axis)


It's a bit weird since HDMI port (DisplayPort-0) seems to detect monitor be=
ing
connected & can get EDID. Is there some bug with enumerating available =
models
caused by DM_MST / TM?
