iommu/vt-d: Per PCI device pasid table interfaces

2018-07-20T12:44:24+00:00

This patch adds the interfaces for per PCI device pasid
table management. Currently we allocate one pasid table
for all PCI devices under the scope of an IOMMU. It's
insecure in some cases where multiple devices under one
single IOMMU unit support PASID features. With per PCI
device pasid table, we can achieve finer protection and
isolation granularity.

iommu/vt-d: Add for_each_device_domain() helper

2018-07-20T12:44:24+00:00

This adds a helper named for_each_device_domain() to iterate
over the elements in device_domain_list and invoke a callback
against each element. This allows to search the device_domain
list in other source files.

iommu/vt-d: Avoid using idr_for_each_entry()

2018-07-20T12:44:23+00:00

idr_for_each_entry() is used to iteratte over idr elements
of a given type. It isn't suitable for the globle pasid idr
since the pasid idr consumer could specify different types
of pointers to bind with a pasid.
