[PATCH 0/14] Page table handling updates for AMD-IOMMU (AMD-Vi)

From: Joerg Roedel
Date: Fri Sep 04 2009 - 05:42:09 EST


this series of patches enhance the page table handling code for
AMD-IOMMU (AMD-Vi). With these patches the page table handling code is
able to map a full 64 bit device address space. The old limit was a 39
bit address space.
This series also contains initial patches for upcoming large page
support in the AMD-Vi driver. Full large page support requires changes
to the IOMMU-API which are not part of this patch set.
