The framework allows callable implementation of IO page table.
This allows AMD IOMMU driver to switch between different types
of AMD IOMMU page tables (e.g. v1 vs. v2).

Is there a reason you created your own framework, there is already an
io-pgtable framework for ARM, maybe that can be reused?


Actually, this is the same framework used by ARM codes.
Sorry if the description is not clear.

Ah, right, thanks. I think this should spend some time in linux-next
before going upstream. Can you please remind me after the next merge
window to pick it up?

Thanks,

Joerg


Sure. Let me send out v2 for this with some more clean up.

Thanks,
Suravee
