When
tir.merge_async_commit_queue_scopeoption is specified asFalse, instead of a singleasync_commit_queue_scopeencompassing severalasync_scopeattributes e.g. as follows:Force each
async_scopeto be in its ownasync_commit_queue_scopeattribute e.g. as follows:And adjust "in flight" wait counts accordingly. In the former case (single
async_commit_queue_scope) the "in flight" wait count is1and in the latter case (multipleasync_commit_queue_scope) the "in flight" wait count isnwherenis the number ofasync_commit_queue_scopeattributes ---2in the example.This enables multiple input async DMA using the same queue / stage on Hexagon where before it was blocked due to the fact that "in flight" counts are managed for each individual DMA with no way to determine if a group of DMAs has completed.
