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?
