+Subject: [PATCH 2004/2940] drm/amdgpu: Need to set the baco cap before baco
+ reset
+
+For passthrough, after rebooted the VM, driver will do
+a baco reset before doing other driver initialization during loading
+ driver. For doing the baco reset, it will first
+check the baco reset capability. So first need to set the
+cap from the vbios information or baco reset won't be
+enabled.
