            Bug ID: 65280
          Assignee: intel-gfx-bugs at lists.freedesktop.org
           Summary: 30bpp displays not working on DP
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: major
    Classification: Unclassified
                OS: All
          Reporter: yangweix.shui at intel.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: DRM/Intel

Environment:

Kernel: (drm-intel-nightly)c5ea23067eb3f0bc86dea95b8f544c7ef8dfea54

Description:
---------------------
We tried 30bpp testing on DP, but find our settings are not really worked. We
dumped the dmesg of "reboot machine and start X", then will find:
[  186.441085] [drm:intel_modeset_pipe_config], plane bpp: 30, pipe bpp: 24,
dithering: 1

So it's not really been set to 30bpp.

Reproduce steps:
---------------------
1. modify /etc/X11/xorg.conf : DefaultDepth 30
2. reboot machine
3. xinit &
4. dmesg | grep -i "plane"
