...ething which seems strange to me: 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 contai...

Hi, I‘m trying to install vTPM based on Xen-4.2.2, linux-kernel 3.9.1 (Dom0) and TPM emulator. However, I cannot find the TPM backed driver in this version of Dom0 linux kernel. There is no CONFIG_XEN_TPMDEV_BACKEND in the kernel config file. The config file for Dom0 is attached. Maybe it provides some useful information. So, how to install a Xen TPM backend driver in the Dom0 linux-kernel.

This series updates the boot protocol to 2.07 and uses it to implement paravirtual booting. This allows the bootloader to tell the kernel what kind of hardware/pseudo-hardware environment it's coming up under, and the kernel can use the appropriate boot sequence code. Specifically: - Update the boot protocol to 2.07, which adds fields to specify the hardware subarchitecture and some

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
