As mentionned by Robin, there are series planning to use
DOMAIN_ATTR_NESTING to get info about the nested caps of the iommu
(ARM

and Intel):
[Patch v8 00/10] vfio: expose virtual Shared Virtual Addressing to VMs
patches 1, 2, 3
Is the plan to introduce a new domain_get_nesting_info ops then?
The plan as usual would be to add it the series adding that support.
Not sure what the merge plans are - if the series is ready to be
merged I could rebase on top of it, otherwise that series will need
to add the method.
OK I think your series may be upstreamed first.
Agree. The vSVA series is still undergoing a refactor according to Jason's
comment thus won't be ready in short term. It's better to let this one
go in first.
Thanks
