[PATCH 08/32] drm/amdkfd: Update MQD management on multi XCC setup
Alex Deucher

Tue Mar 28 15:13:20 UTC 2023
From: Mukul Joshi <mukul.joshi at amd.com>
Update MQD management for both HIQ and user-mode compute
queues on a multi XCC setup. MQDs needs to be allocated,
initialized, loaded and destroyed for each XCC in the KFD
node.
