...both cases in one place. The changes currently hook into get_page_type() in xen/arch/x86/mm.c to map/unmap IOMMU pages when the page types change. This might not be the apropriate place to hook these calls. The patches I''ve added are as follows: xen-vtd-unmap.patch --- Make the VT-d iommu_unmap_page() code actually do something close to useful. xen-ptab-dump.path --- There''s no point in using ''current'' when an IOMMU page fault is raised. Also, add some page type statistics for DomPage debug output. xen-iommu-pv.patch --- Add support for...

Hi, This is third approach (complete this time) for replacing struct dma_attrs with unsigned long. The main patch (2/45) doing the change is split into many subpatches for easier review (3-43). They should be squashed together when applying. *Important:* Patchset is *only* build tested on allyesconfigs: ARM, ARM64, i386, x86_64 and powerpc. Please provide reviewes and tests for other

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

Hello everyone, this is the fourth version of the patch series that introduces ARMv7 with virtualization extensions support in Xen. The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile Express simulator. See the following announce email for more informations about what we are trying to achieve, as well as the original git history: See
