Sorry I should be clearer.
dev->gpu->pci_atomic_requested is set to the value of
adev->have_atomics_support - see function amdgpu_amdkfd_have_atomics_support.
adev->have_atomics_support is set through function
pci_enable_atomic_ops_to_root currently in amdgpu_device_init - I don't think
this

I think part of this can be done more clean in amdgpu_device_init:
r = 0;
If (!adev->gmc.xgmi.connected_to_cpu)
/* enable PCIE atomic ops */
r = pci_enable_atomic_ops_to_root(adev->pdev,
PCI_EXP_DEVCAP2_ATOMI

I don't understand this change. I don't see any code that gets executed
if (adev->gmc.xgmi.connected_to_cpu). Where is the code that reports
atomics support for this case?
A
Link atomics support over xGMI should be reported independently of PCIe.
