From: Jeremy Fitzhardinge Subject: [patch 00/34] Xen-pv_ops: Xen guest implementation for paravirt_ops interface Date: Tue, 13 Mar 2007 16:30:17 -0700 Message-ID: <20070313233017.933601256@goop.org> Return-path: List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: xen-devel-bounces@lists.xensource.com Errors-To: xen-devel-bounces@lists.xensource.com To: Andi Kleen Cc: Zachary Amsden , xen-devel@lists.xensource.com, Rusty Russell , linux-kernel@vger.kernel.org, Chris Wright , virtualization@lists.osdl.org, Andrew Morton List-Id: virtualization@lists.linuxfoundation.org Hi Andi, This patch series implements the Linux Xen guest as a paravirt_ops backend. The features in implemented this patch series are: * domU only * UP and SMP guest support (NEW!) * dynamic ticks (NEW!) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes (non-PAE may be broken at the moment) * 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 3-19 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. 19-34 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-rc3-git7. Changes since the previous posting: - SMP support - Implemented xen_clockevent, so Xen is fully compatible with CONFIG_NO_HZ and HIGH_RES_TIMERS. - Finished implementing late pinning/early unpinning of pagetables, which should now be equivalent to xen-unstable in performance. - Add kmap_atomic_pte for mapping ptes, and therefore support for HIGHPTE - Fixed crash on systems with >= 4G memory - Cleanup netfront (Stephen Hemminger) - Add MAINTAINERS entries - Fold kill-HAVE_ARCH_MM_LIFETIME.patch into mm-lifetime-hooks.patch - rebased Thanks, J --
