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?

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.

That message is from kfd. It's for ROCm. Unrelated to DC

No, DC has nothing to do with pci atomics. DC is enabled:
[ 8.690697] [drm] Display Core initialized with v3.2.02!
