similar to: [patch 12/19] xen: deal with stale cr3 values when unpinning pagetables

[ I think this is a straight repost this patch, which addresses all the previous comments. I'd like to submit this for .24 as the basis for a unified paravirt_ops. Any objections? ] Currently, the set_lazy_mode pv_op is overloaded with 5 functions: 1. enter lazy cpu mode 2. leave lazy cpu mode 3. enter lazy mmu mode 4. leave lazy mmu mode 5. flush pending batched operations This

Currently, the set_lazy_mode pv_op is overloaded with 5 functions: 1. enter lazy cpu mode 2. leave lazy cpu mode 3. enter lazy mmu mode 4. leave lazy mmu mode 5. flush pending batched operations This complicates each paravirt backend, since it needs to deal with all the possible state transitions, handling flushing, etc. In particular, flushing is quite distinct from the other 4 functions,

This is my current set of updates to Xen for 2.6.24. This is largely a bugfix set, and a couple of them are also relevent to 2.6.23. These are in the pre-x86 merge form; I'll update them once the merge goes into git. Quick overview: - remove some dead code in arch/i386/mm/init.c - clean up some duplicate includes - when sending an IPI, yield the vcpu if the destination doesn't have

Hi Linus, Here's a set of patches to update paravirt_ops and Xen for 2.6.24 A quick overview of the patchset: paravirt_ops: Remove the monolithic paravirt_ops structure, and replace it with smaller structures of related functions. Also, clean up the handling of lazy mode to make it easier to implement. x86/mm/init.c: remove a chunk of dead code Xen: - remove duplicate includes -

This adds an smp_ops for voyager, and hooks things up appropriately. This is the first baby-step to making subarch runtime switchable.

Package: xen-hypervisor-4.0-amd64 Version: 4.0.1-5.2 Severity: important Tags: patch I have a system based on a Supermicro X8DTH-i motherboard and a Xeon E5506 CPU. It was previously running Debian lenny with xen-hypervisor-3.2-1-amd64 / linux-image-2.6.26-2-xen-amd64 without incident. I upgraded it to Debian squeeze, with xen-hypervisor-4.0-amd64 / linux-image-2.6.32-5-xen-amd64 and now it does

Presumably as a result of recent changes, FreeBSD no longer works with writable page tables. In the short-term I''m more interested in functionality than performance. This patch disables them and fixes a compile issue. # This is a BitKeeper generated diff -Nru style patch. # # ChangeSet # 2005/04/29 19:26:00-07:00 kmacy@curly.lab.netapp.com # disable writable pagetables + compile

This is a patch repairing a regression in code previously functional in 4.1.x. It appears that, during some refactoring work, calls to hvm_memory_event_cr3 and hvm_memory_event_cr4 were lost. These functions were originally called in mov_to_cr() of vmx.c, but the commit http://xenbits.xen.org/hg/xen-unstable.hg/rev/1276926e3795 abstracted the original code into generic functions up a level in

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.
