Hi,
I noted that the comments in vfio_iommu_type1_attach_group:
/*
* Try to match an existing compatible domain. We don't want to
* preclude an IOMMU driver supporting multiple bus_types and
being
* able to include different bus_types in the same IOMMU domain,
so
* we test whether the domains use the same iommu_ops rather than
* testing if they're on the same bus_type.
*/
In intel x86 platforms currently, can I think a virtual machine have a
one-to-one association with a vfio container,
and a vfio container have a one-to-one association with a iommu_domain?.
Does there exist any scene or system that two domains use two different
iommu_ops?
Thanks,
Wu Zongyong
