While adding code to create the compatibility p2m table mappings it seemed to me that the creation of the native ones is restricted to memory below the 512G boundary - otherwise, additional L2 tables would need to be allocated (currently other memory following the one L2 page getting allocated would be blindly overwritten). While I realize that machines this big aren''t likely to be

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.

Hi, V6: The only change from V5 is in patch #6: - changed comment to reflect autoxlate - removed a redundant ASSERT - reworked logic a bit so that get_page_from_gfn() is called with NULL for p2m type as before. arm has ASSERT wanting it to be NULL. Tim: patch 4 needs your approval. Daniel: patch 5 needs your approval. These patches implement PVH dom0. Patches 1 and 2

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

Hi all, this patch series makes the necessary changes to make sure that the current ARM hypercall ABI can be used as-is on 64 bit ARM platforms: - it defines xen_ulong_t as uint64_t on ARM; - it introduces a new macro to handle guest pointers, called XEN_GUEST_HANDLE_PARAM (that has size 4 bytes on aarch and is going to have size 8 bytes on aarch64); - it replaces all the occurrences of
