When
tir.merge_async_commit_queue_scope
option is specified asFalse
, instead of a singleasync_commit_queue_scope
encompassing severalasync_scope
attributes e.g. as follows:Force each
async_scope
to be in its ownasync_commit_queue_scope
attribute 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 is1
and in the latter case (multipleasync_commit_queue_scope
) the "in flight" wait count isn
wheren
is the number ofasync_commit_queue_scope
attributes ---2
in 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.
