* identity mapped. To use this feature, users need to pass in the

* PIPELINED
* This flag allows the copy/memset operation to be pipelined with previous dma operations on the same channel
* It means that its reads/writes are allowed happen before writes of preceding operations are tlb-acked
* The flag can be useful when dealing with non-inersecting async operations,
* but it can result in races when 2 async CE operations target the same allocation, and the second operation uses the flag
* Race example:
* 1. async copy A -> B
* 2. pipelined copy B -> C
* Here copy 2 can read B before copy finishes writing it, which will result in C containing invalid data
* Technical details:
* By default, first _LAUNCH_DMA method of a CE operation is marked has _TRANSFER_TYPE_NON_PIPELINED, which the flag overrides
* Subsequent _LAUNCH_DMA methods belonging to the same operation use _TRANSFER_TYPE_PIPELINED, as each of these methods should
* target different addresses
*
* submittedWorkId [OUT]
* The work submission token users can poll on to wait for work
