iommu/vt-d: Fix QI_DEV_IOTLB_PFSID and QI_DEV_EIOTLB_PFSID macros

2019-11-20T17:45:19+00:00

commit 4e7120d79edb31e4ee68e6f8421448e4603be1e9 upstream.

For both PASID-based-Device-TLB Invalidate Descriptor and
Device-TLB Invalidate Descriptor, the Physical Function Source-ID
value is split according to this layout:

PFSID[3:0] is set at offset 12 and PFSID[15:4] is put at offset 52.
Fix the part laid out at offset 52.

The obsolete per iommu pasid tables are no longer used. Hence,
clean up them.

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.

Revert "iommu/vt-d: Clean up pasid quirk for pre-production devices"

2018-07-20T11:55:56+00:00

This reverts commit ab96746aaa344fb720a198245a837e266fad3b62.

The commit ab96746aaa34 ("iommu/vt-d: Clean up pasid quirk for
pre-production devices") triggers ECS mode on some platforms
which have broken ECS support. As the result, graphic device
will be inoperable on boot.
