+ * @wave_cnt: Output parameter updated with number of waves in flight that
+ * belong to process with given pasid
+ * @max_waves_per_cu: Output parameter updated with maximum number of waves
+ * possible per Compute Unit
+ *
+ * @note: It's possible that the device has too many queues (oversubscription)
+ * in which case a VMID could be remapped to a different PASID. This could lead
+ * to an iaccurate wave count. Following is a high-level sequence:
+ * Time T1: vmid = getVmid(); vmid is associated with Pasid P1
+ * Time T2: passId = getPasId(vmid); vmid is associated with Pasid P2
+ * In the sequence above wave count obtained from time T1 will be incorrectly
+ * lost or added to total wave count.
+ *
+ * The registers that provide the waves in flight are:
+ *
+ * SPI_CSQ_WF_ACTIVE_STATUS - bit-map of queues per pipe. The bit is ON if a
+ * queue is slotted, OFF if there is no queue. A process could have ZERO or
+ * more queues slotted and submitting waves to be run on compute units. Even
+ * when there is a queue it is possible there could be zero wave fronts, this
+ * can happen when queue is waiting on top-of-pipe events - e.g. waitRegMem
+ * command
+ *
+ * For each bit that is ON from above:
+ *
+ * Read (SPI_CSQ_WF_ACTIVE_COUNT_0 + queue_idx) register. It provides the
+ * number of waves that are in flight for the queue at specified index. The
+ * index ranges from 0 to 7.
+ *
+ * If non-zero waves are in flight, read CP_HQD_VMID register to obtain VMID
+ * of the wave(s).
+ *
+ * Determine if VMID from above step maps to pasid provided as parameter. If
+ * it matches agrregate the wave count. That the VMID will not match pasid is
+ * a normal condition i.e. a device is expected to support multiple queues
+ * from multiple proceses.
+ *
+ * Reading registers referenced above involves programming GRBM appropriately
