X-Git-Tag: microblaze-v6.6~1850^2~1^2~6 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=8fe8ce896c1cc29d6bfebb3c7b3cc948f72cd32c;p=linux-2.6-microblaze.git drm/amdgpu: Disable GPU reset on SRIOV before remove pci. The recent change brought a bug on SRIOV envrionment. It caused unloading amdgpu failed on Guest VM. The reason is that the VF FLR was requested while unloading amdgpu driver, but the VF FLR of SRIOV sequence is wrong while removing PCI device. For SRIOV, the guest driver should not trigger the whole XGMI hive to do the reset. Host driver control how the device been reset.
