v2, right?

Resource allocation happens in compute_allocate_resource in src/devices/device.c

That function gets passed a type and a type mask.  Depending on what
type the children's resources are they get added to the Mem/Prefetch
allocation.  In the log you should be able to see calls to
compute_allocate_resource and follow it through.

Good Luck,
