Thanks, I think I get your point. With hive!= NULL, it never fails on the amdgpu_device_lock_adev(). Sorry for miss that. Will send a new patch.

For XGMI setup(multiple dgpus > interconnected with bridges), the "hive" here is not NULL. Presumably you are talking about out of tree code so I can't comment on this. In the current linux-next we know that amdgpu_device_lock_adev() will only return false when "hive" is NULL. regards, dan carpenter _______________________________________________ amd-gfx mailing list amd-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/amd-gfx
