+Subject: [PATCH 3392/4131] drm/amd: Update kgd_kfd interface for resuming SDMA
+ queues
+
+Add wptr and mm parameters to hqd_sdma_load and pass these parameters
+from device_queue_manager through the mqd_manager.
+
+SDMA doesn't support polling while the engine believes it's idle. The
+driver must update the wptr. The new parameters will be used for looking
+up the updated value from the specified mm when SDMA queues are resumed
+after being disabled.
