CP_HQD_HQ_STATUS0[29] bit will be used by CPFW to acknowledge whether
PCIe atomics are supported. The default value of this bit is set
to 0. Driver will check whether PCIe atomics are supported and set the
bit to 1 if supported. This will force CPFW to use real atomic ops.
If the bit is not set, CPFW will default to read/modify/write using the
firmware itself.
This is applicable only to GFX11 RS64 CP with MEC FW >= 509. If MEC
FW < 509 and for all GFX11 F32 CP, PCIe atomics needs to be supported
else it will skip the device.

Remove the redundant pci_enable_pcie_error_reporting() call from the

Note that this only controls ERR_* Messages from the device. An ERR_*

This reverts commit fac53471d0.
The following change: move the drm_dev_unplug call after
amdgpu_driver_unload_kms in amdgpu_pci_remove. The reason is
the following: amdgpu_pci_remove calls drm_dev_unregister
and it should be called first to ensure userspace can't access the
device instance anymore. If we call drm_dev_unplug after
amdgpu_driver_unload_kms then we observe IGT PCI software unplug
test failure (kernel hung) for all ASICs. This is how this
regression was found.
After this revert, the following commands do work not, but it would
