* 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.
