           Summary: AMDGPU/DC: Internal display corrupted when mirroring
                    on external monitor on HDMI
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org

Same machine as on the https://bugs.freedesktop.org/show_bug.cgi?id=104281 but
reproduced on multiple ACER laptops.

Using the latest Linus master compiled with CONFIG_DRM_AMD_DC_PRE_VEGA=y we
have that sometimes the image on the internal panel gets corrupted when
mirroring on an external HDMI display (see [0]).

We have verified that this is a regression introduced by the DC code. In
attachment the journal output.

We have also verified that when disconnecting the HDMI cable, the system is not
stable anymore, with corruption and flickering on the internal panel also
without the HDMI cable connected.

As you can see from the attached journal that the log is filled with WARNINGS
from the DC code.

I just reproduced the same issue this time with the external HDMI monitor in
extended mode, not mirroring. It attachment the log.

Need to do more testing to be sure, but it appears that this is not
reproducible on the development branch
https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next

Thanks, Daniel. The fix should land for 4.16 then.

Marking resolved as reported to work fine on amd-staging-drm-next. If this is
still an issue feel free to reopen.
