Hi. Recently the xen-ia64 community started to make efforts to merge xen/ia64 Linux to upstream. The first step is to merge up domU portion. This patchset is preliminary for xen/ia64 domU linux making the current xen/x86 domU code more arch generic and adding missing definitions and files. Diffstat: arch/x86/xen/Makefile | 4 +- arch/x86/xen/grant-table.c | 91

Hi Jeremy. According to your suggestion, I recreated patches for Ingo's x86.git tree. And this patch series includes Eddie's modification. Please review and forward them. (or push back to respin.)

This patch series implements the Linux Xen guest in terms of the paravirt-ops interface. The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen console * virtual block

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths

Hi Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-rc7 + your patches + the last batch of pv_ops patches I posted. This patch generally restricts itself to Xen-specific parts of the tree, though it does make a few small changes elsewhere. These patches include: - some helper routines for allocating address space and walking pagetables - Xen
