            Bug ID: 108570
           Summary: AMDGPU DC Not workin on PCI Express 2.0?
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: TestMode11@protonmail.com

On RX560 I get the following in dmesg

[    8.426625] kfd kfd: skipped device 1002:67ef, PCI rejects atomics

Then in Weston start log I do not see "DRM supports atomic modesetting". 

Does this mean that DC is not active? Do AMDGPU DC and atomic modesetting only
work with PCI Express 3.0?
