Description
Task1: Update runtime configuration APIs to:
- enable out-of-order mode at S2MM, and (set through
amdaie.dma_startfor mem; not supported for shim, so no need to setamdaie.npu.push_to_queue) - configure out-of-order BD ID at MM2S (set through
amdaie.npu.write_bdfor shim,amdaie.dma_bd_packetfor mem)
Task2: Create a new transformation pass to decide when/where to use out-of-order
- link the correct BD ID between S2MM and MM2S (require all the BDs have been assigned)
- out-of-order can only be used for packet flows (and packet header should not be dropped by stream switch, by setting
keep_pkt_headerinamdaie.flow) - set up repeat_count. For out-of-order mode, this value should represent the total number of transmissions across all BDs within a block (require non-circular DmaCpyNd?)
