+/**
+ * DOC: Multi Queue Group
+ *
+ * Multi Queue Group is another mode of execution supported by the compute
+ * and blitter copy command streamers (CCS and BCS, respectively). It is
+ * an enhancement of the existing hardware architecture and leverages the
+ * same submission model. It enables support for efficient, parallel
+ * execution of multiple queues within a single shared context. The multi
+ * queue group functionality is only supported with GuC submission backend.
+ * All the queues of a group must use the same address space (VM).
+ *
+ * The DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE execution queue property
+ * supports creating a multi queue group and adding queues to a queue group.
+ *
+ * The XE_EXEC_QUEUE_CREATE ioctl call with above property with value field
+ * set to DRM_XE_MULTI_GROUP_CREATE, will create a new multi queue group with
+ * the queue being created as the primary queue (aka q0) of the group. To add
+ * secondary queues to the group, they need to be created with the above
+ * property with id of the primary queue as the value. The properties of
+ * the primary queue (like priority, time slice) applies to the whole group.
+ * So, these properties can't be set for secondary queues of a group.
+ *
+ * The hardware does not support removing a queue from a multi-queue group.
+ * However, queues can be dynamically added to the group. A group can have
+ * up to 64 queues. To support this, XeKMD holds references to LRCs of the
+ * queues even after the queues are destroyed by the user until the whole
+ * group is destroyed. The secondary queues hold a reference to the primary
+ * queue thus preventing the group from being destroyed when user destroys
+ * the primary queue. Once the primary queue is destroyed, secondary queues
+ * can't be added to the queue group and new job submissions on existing
+ * secondary queues are not allowed.
+ *
+ * The queues of a multi queue group can set their priority within the group
+ * through the DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE_PRIORITY property.
+ * This multi queue priority can also be set dynamically through the
+ * XE_EXEC_QUEUE_SET_PROPERTY ioctl. This is the only other property
+ * supported by the secondary queues of a multi queue group, other than
+ * DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE.
+ *
+ * When GuC reports an error on any of the queues of a multi queue group,
+ * the queue cleanup mechanism is invoked for all the queues of the group
+ * as hardware cannot make progress on the multi queue context.
+ *
+ * Refer :ref:`multi-queue-group-guc-interface` for multi queue group GuC
+ * interface.
