From: Sai Praneeth <[email protected]>Presently, "/sys/kernel/debug/iommu/intel/dmar_translation_struct" file dumps only legacy DMAR table which consists of root table and context table. Scalable mode DMAR table adds PASID directory and PASID table. Hence, add support to dump these tables as well. Directly extending the present dumping format for PASID tables will make the output look clumsy. Hence, the first patch modifies the present format to a tabular format. The second patch introduces macros that are used during PASID table walk and the third patch actually adds support to dump scalable mode DMAR table.

This patch set looks good to me in general. One minor suggestion is that the author name and signed-of-by name should be consistent for all patches. Best regards, Lu Baolu
