Prior to this commit, the
dlight
scheduling rules were applied solely based on the globaltvm.target.Target.current()
. However, a TIR PrimFunc may be annotated with the target, rather than using the globalTarget.current()
. In this case, thedlight
scheduling may produce a scheduled PrimFunc that is not compatible with its target. For example, using a thread binding to"threadIdx.x"
on a CPU target.This commit updates
dlight
to check for a TIR PrimFunc's annotations when scheduling, matching the behavior oftvm.build
.
