Linux Plumbers Conf 2014

One Line Summary

Abstract

I’ve heard about people using IOMMUs for things like modifying the memory type of memory transactions (e.g. changing non-cacheable transactions to cacheable), without needing to set up page tables etc.

This would be a good opportunity to talk to vendors about how they are using these sort of features and whether or not we should extend the IOMMU core API to support such features.
