Use this field to save the pasid/ssid bits that a device is able to
support with its IOMMU hardware. It is a generic attribute of a device
and lifting it into the per-device dev_iommu struct makes it possible
to allocate a PASID for device without calls into the IOMMU drivers.
Any iommu driver which suports PASID related features should set this
field before features are enabled on the devices.
For initialization of this field in the VT-d driver, the
info->pasid_supported is only set for PCI devices. So the status is
that non-PCI SVA hasn't been supported yet. Setting this field only for
PCI devices has no functional change.
