This patch series restores the use of superpages when restoring or migrating a VM, while retaining efficient batching of 4k pages when superpages are not appropriate or available.

This patch series includes a series of bugs related to p2m, ept, and PoD code which were found as part of our XenServer product testing. Each of these fixes actual bugs, and the 3.4-based version of the patch has been tested thoroughly. (There may be bugs in porting the patches, but most of them are simple enough as to make it unlikely.) Each patch is conceptually independent, so they can each

Noticed that on change set 12568, we change the valid_mfn to be in fact the mfn_valid(). Then on change set 12572, we change the shadow_set_p2m_entry() to use mfn_valid(). I''m a bit confused by this change. I think current meaning of mfn_valid() is to check if the mfn is valid RAM. It is ok for page table pages. But for p2m table, considering shadow for driver domain or considering IOMMU

Hi all, this patch series enables xen-swiotlb on arm and arm64. It has been heavily reworked compared to the previous versions in order to achieve better performances and to address review comments. We are not using dma_mark_clean to ensure coherency anymore. We call the platform implementation of map_page and unmap_page. We assume that dom0 has been mapped 1:1 (physical address == machine

There has been some progress, but still no joy. Definitely not intended for inclusion at this point. Tim, Wei, I added a Xen command line toggle to disable IOMMU and P2M table sharing. Tim, I verified that changes to p2m-pt.c don''t break shadow mode (64bit hypervisor and Win 7 guest). Hongkaixing, I incorporated your suggestion in patch 2, so I should add your Signed-off-by eventually.

Populate-on-demand: Check pages being returned by the balloon driver This patch series is the second result of my work last summer on decreasing fragmentation of superpages in a guests'' p2m when using populate-on-demand. This patch series is against 4.1; I''m posting it to get feedback on the viability of getting a ported version of this patch into 4.2. As with the previous

This set of patches adds the support for acceleration plugins to the netfront/netback drivers. These plugins are intended to support virtualisable network hardware that can be directly accessed from the guest, bypassing dom0. This is in response to the RFC we posted to xen-devel with an outline of our approach at the end of September. To follow will be another set of patches to provide our

The following 5 patches are re-submissions of the vt-d patch. This set of patches has been tested against cs# 15080 and is now much more mature and tested against more environments than the original patch. Specifically, we have successfully tested the patch with following environements: - 32/64-bit Linux HVM guest - 32-bit Windows XP/Vista (64-bit should work but did not test) -
