[Bug 109340] HDMI output (DisplayPort-0) stops listing modes after using docking station DP output

Bug ID: 109340 Summary: HDMI output (DisplayPort-0) stops listing modes after using docking station DP output Product: DRI Version: XOrg git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: zajec5@gmail.com

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 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 & gets EDID but xrandr doesn't list any modes.
After booting without docking station & connecting monitor using HDMI port: DisplayPort-0 connected (normal left inverted right x axis y axis) 1920x1080 60.00 + 50.00 59.94 1680x1050 59.88 1600x900 60.00 1280x1024 60.02 1440x900 60.00 1280x800 59.91 1280x720 60.00 50.00 59.94 1024x768 60.00 800x600 60.32 720x576 50.00 720x480 60.00 59.94 640x480 60.00 59.94

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 being connected & can get EDID. Is there some bug with enumerating available models caused by DM_MST / TM?

--- Comment #2 from Rafał Miłecki zajec5@gmail.com --- I've noticed that:
1) After connecting monitor to the docking station's DP output following outputs appear: DisplayPort-3, DisplayPort-4 and DisplayPort-5. 2) After disconnecting monitor from docking stating I can see: [drm] DM_MST: stopping TM on aconnector: 00000000651bd996 [id: 57] [drm] DM_MST: Disabling connector: 00000000e1b7686d [id: 90] [master: 00000000651bd996] [drm] DM_MST: Disabling connector: 0000000078869ed2 [id: 94] [master: 00000000651bd996] [drm] DM_MST: Disabling connector: 00000000af4e5879 [id: 98] [master: 00000000651bd996] 3) After disconnecting whole docking station I can still see DisplayPort-3, DisplayPort-4 and DisplayPort-5 in the "xrandr" output.
Is that expected? Is that a possible hint for some problem with output management that also causes the original problem?

--- Comment #3 from Rafał Miłecki zajec5@gmail.com --- This problem also occurs when using drm/drm branch drm-next (5.0.0-rc1) with: [PATCH v7 00/20] MST refcounting/atomic helpers cleanup on top of it.
The only difference I've noticed is xrandr complaining about MIT-MAGIC-COOKIE-1:
xrandr

--- Comment #6 from Rafał Miłecki zajec5@gmail.com --- Created attachment 143104 --> https://bugs.freedesktop.org/attachment.cgi?id=143104&action=edit Xorg.0.log using xf86-video-modesetting
Michel has suggested trying xf86-video-modesetting. A difference from user perspective is minimal.
1) With both drivers I can use HDMI output port just fine after booting (without a docking station)
2) After that I connect docking station, connect DP, disconnect DP, disconnect docking station
3) Finally I try connecting monitor to the HDMI output again: a) With xorg-xf86-video-amdgpu I get "Output DisplayPort-0 is not disconnected but has no modes" b) With xf86-video-modesetting I get "xrandr: Configure crtc 1 failed"
