Subject: [PATCH 2686/2940] drm/amdkfd: kfd expose the hive_id of the device
through its node properties
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Thunk will generate the XGMI topology information when necessary with the hive_id
for each specified device
