Ok thanks for the detailed info, but what about the case where the same
iommu group is used by two primary processes?
I don't know how frequent it is, but if ACS is not supported by either
the endpoint or the the root port, then you would have to share the same
IOMMU group for all the ports of your card. Right?

I don't question the need of the feature for these kind of
co-processors, using VA as IOVA in your case seems very valid.
What concerns me is that we change the default behavior for all other
devices. Having an option to override is fine to me, but the default
mode should remain the same IMHO.
Wouldn't it be possible to default to VA as IOVA only when an HW mempool
is in use?
