Attacking the Qualcomm Adreno GPU

There is an IOMMU on snapdragons, as the article says, but it is the IOMMU mapping itself which they attack.

This itself is kind of mind boggling how they let the device overwrite its own IOMMU configuration, effectively nullifying IOMMU's purpose, and its provided safeties.

It's like fencing your house with 10 meter high walls, but leaving the key lying in front of the gate.

So, like you say: they don't have an IOMMU, although they have some dingus which is called an "IOMMU".
