Hi,
Any comments on this? I know we have some opens w.r.t. PASID management
UAPI, but I think having this common kernel API features should be
justified.
Thanks!

IOASID was introduced in v5.5 as a generic kernel allocator service for
both PCIe Process Address Space ID (PASID) and ARM SMMU's Sub Stream
ID. In addition to basic ID allocation, ioasid_set was defined as a
token that is shared by a group of IOASIDs. This set token can be used
for permission
