            Bug ID: 109238
           Summary: [DC] Polaris10: Missing modes when enabling DC
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org

Xorg.0.log with modesetting

+++ This bug was initially created as a clone of Bug #103953 +++

I have 3 Dell WQHD Screens (2560x1440) screens, connected to a Radeon RX580
(XFX, RX-580 GTS Black Edition, 1425 MHz 8GB).

My kernel is:

Linux edison 4.19.13-300.fc29.x86_64 #1 SMP Sat Dec 29 22:54:28 UTC 2018 x86_64
x86_64 x86_64 GNU/Linux

With the default boot settings, which enable amdgpu.dc, I am unable to get the
native resolution on one of the three monitors.

If I disable amdgpu.dc on the kernel command line, I am able to get the native
resolution on all three monitors.

I have attached the Xorg.0.conf.old from the startup with amdgpu.dc at the
default setting, and Xorg.0.conf from the startup with amdgpu.dc=0.

I have also attached the initial part of the dmesg log from both boots:

dmesg-amdgpudcdefault.log : default amdgpu.dc setting (enabled)
dmesg-amdgpudc0.log : amdgpu.dc=0

The only relevant difference I see between the two is that with modesetting, I
see the following errors:

 edison kernel: amdgpu: [powerplay] Failed to retrieve minimum clocks.
 edison kernel: amdgpu: [powerplay] Error in phm_get_clock_info 

whereas without modesetting I do not see those errors.

Still have this issue, with a totally different card: RX590 made by Asus.
