This is a follow-up to the discussion thread here:
https://lore.kernel.org/linux-iommu/20240201193427.GQ50608@ziepe.ca/
This proposes a per-IOMMU red-black tree for iommu probed devices. It benefits fault handling paths, where the VT-d hardware reports the Source ID of the related device, and software needs to retrieve the corresponding device pointer based on this ID.
Lu Baolu (2): iommu/vt-d: Use rbtree to track iommu probed devices iommu/vt-d: Use device rbtree in iopf reporting path
