Hi Andi, 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 device (blockfront) * virtual network device (netfront) The patch series is in two parts: 1-12: cleanups to the core kernel, either to fix outright problems, or to add appropriate hooks for Xen 13-21: the Xen guest implementation itself I've tried to make each patch as self-explanatory as possible. The series is based on git changeset ec2f9d1331f658433411c58077871e1eef4ee1b4 + x86_64-2.6.20-git8-070213-1.patch. Changes since the previous posting: - rebased - addressed review comments: - deal with missing vga hardware better - deal with Andi's comments - clean up header file placement - update netfront, and move it into drivers/net I looked at linking in xen-head.S rather than including it into xen-head.S, but it seems to provoke linker bugs, so I've left it as-is for now. Thanks, J --
