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 hvc console (console=hvc0) * virtual block device (blockfront) * virtual network device (netfront) The patch series is in three parts: 1- 2 Cleanup patches to various parts of the kernel 3-14 Extensions to the core code and/or paravirt ops, needed to support Xen. Includes hooks into get/setting pte values and the new patching machinery. 15-26 The Xen paravirt_ops implementation itself. (Some of the earlier patches in the series have already been posted, but are included to make the series self-contained.) I've tried to make each patch as self-explanatory as possible. The series is based on 2.6.21-rc1. Changes since the previous posting: - implemented new patching scheme, which should make the overhead of running on native approach zero, and Xen overhead a fair bit lower - rebased - some small review comment updates - trailing whitespace stripped - accurate diffstats Thanks, J --
