[PATCH v4 0/7] iommu/vt-d: Some cleanups

From: Lu Baolu
Date: Fri Nov 18 2022 - 08:32:47 EST


Hi,

This series includes some cleanups in the Intel IOMMU implementation
after the IOMMU core implemented the blocking domain. The cleanup work
is mainly in the attach_dev/device_probe/device_release paths.

Please help to review.

Best regards,
baolu

Change log:
v4:
- Drop the change of "Fold dmar_remove_one_dev_info() into its caller"
in order to avoid an inextricable ordering problem.

v3:
- https://lore.kernel.org/linux-iommu/20221114014049.3959-1-baolu.lu@xxxxxxxxxxxxxxx/
- Disable PCI capabilities (PASID/ATS/PRI) when there's no domain
attached to the device.

v2:
- https://lore.kernel.org/linux-iommu/20221108073408.1005721-1-baolu.lu@xxxxxxxxxxxxxxx/
- Reorder the patches to make the device_block_translation() work with
the existing path first.
- Add a new patch to improve iommu_enable_pci_caps().

v1:
- https://lore.kernel.org/linux-iommu/20221103055329.633052-1-baolu.lu@xxxxxxxxxxxxxxx/
