...: the build_pagetable() function in mm.c. This function aims at building up the additional page tables which were not allocated by the hypervisor during the domain construction (domain_build.c). I do not understand the following calculation: pfn_to_map = (start_info.nr_pt_frames - NOT_L1_FRAMES) * L1_PAGETABLE_ENTRIES; pfn_to_map is supposed to be the first page frame number to be mapped by the function. However, the guest OS gets a list of pfns (start_pfn - max_pfn, including the phys_to_machine table) assigned by the hypervisor, and the first pfns are supposed to contain the startup code and initial page tabl...

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.

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.

Hello, This series has been split into two patches, one for arm and one for x86. I figured that this was easier than doing it as a single combined patch, especially as the changes are functionally independent. x86 has been boot tested, but arm has not even been compile tested as I lack a suitable cross compiler. However, the changes are just text replacement, so I dont expect any issues. The

This patch series contains a set of patches making minios rather easier to use, from an application development point of view. Overview of patches: 1 Command line argument parsing support, from Xen. 2 Weak console handler function. 3 Build system tweaks for application directories. 4 Trailing whitespace cleanup. (because it is very messy) Patch 4 is likely to be more controversial than
