+ * struct mqd_manager
+ *
+ * @init_mqd: Allocates the mqd buffer on local gpu memory and initialize it.
+ *
+ * @load_mqd: Loads the mqd to a concrete hqd slot. Used only for no cp
+ * scheduling mode.
+ *
+ * @update_mqd: Handles a update call for the MQD
+ *
+ * @destroy_mqd: Destroys the HQD slot and by that preempt the relevant queue.
+ * Used only for no cp scheduling.
+ *
+ * @uninit_mqd: Releases the mqd buffer from local gpu memory.
+ *
+ * @is_occupied: Checks if the relevant HQD slot is occupied.
+ *
+ * @mqd_mutex: Mqd manager mutex.
+ *
+ * @dev: The kfd device structure coupled with this module.
+ *
+ * MQD stands for Memory Queue Descriptor which represents the current queue
+ * state in the memory and initiate the HQD (Hardware Queue Descriptor) state.
+ * This structure is actually a base class for the different types of MQDs
+ * structures for the variant ASICs that should be supported in the future.
+ * This base class is also contains all the MQD specific operations.
+ * Another important thing to mention is that each queue has a MQD that keeps
+ * his state (or context) after each preemption or reassignment.
+ * Basically there are a instances of the mqd manager class per MQD type per ASIC,
+ * Currently the kfd driver supports only Kaveri so there are instances per
+ * KFD_MQD_TYPE for each device.
