Subject: drm/amdgpu: enable xgmi support for Aldebaran
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=efce10005be4023e23ed51fe1c2e8380d5fe62d4;p=linux.git

drm/amdgpu: enable xgmi support for Aldebaran

Like its predecessors Aldebran also supports advanced high bandwidth
GPU-GPU communication interface known as xgmi. This enables the basic
xgmi support while refactoring the code slightly.

Detection of xgmi link between host cpu and gpu will be introduced in a
different patch.
