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?
I don't believe there is any connection between "atomic" modesetting and atomic operations in PCIE 3.0. Do you see other DC-related messages ? Might be helpful to post your full dmesg output.

Not seeing any DC success or error messages - though not clear how these would look.

Do AMDGPU DC and atomic modesetting > only work with PCI Express 3.0? No, DC has nothing to do with pci atomics. DC is enabled: [ 8.690697] [drm] Display Core initialized with v3.2.02!
