hi, it seems I no longer need to pin l1 pages when running with writable page tables in xen-unstable -- e.g. I can now pin a l2 table without having pinned its l1 descendants first, without Xen complaining. Do I understand things correctly? thanks, Jacob _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

At OLS I gave a talk on some of the Xen scalability inhibitors, and one of these was writable page tables. We went over why the feature does not scale, but just as important, we found that the uniprocessor case does not provide any advantage either. These tests were done on x86_64, so I wanted to run the 1-way test on 32 bit to show the same problem. So, I have run with writable PTs and

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

I''m trying to recompile wxRuby 0.6 using Borland''s C++ Compiler (version 5.5.1). So far I was able to do the following: 1) Recompile a working version of ruby V1.8.1 executable using bcc32 2) Recompile a working version of wxWindows 2.4.2 using bcc32   However for wxruby, I''m having some problems with the Makefile which I fixed. Now when I''m compiling the

I want to know any difference between writing, reading and shadow page table (for example performance). I am thankful for any help or resource for that. -- Best Regards Mohamad Taghi Mir Mohamad Rezaie Iran University of Science and Technology Department of Computer Science & Engineering System Software Group _______________________________________________ Xen-devel mailing list

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

Hi Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-git13 + patches-2.6.21-git7-070507-1.tar.gz (I think "unwinder" is the only patch which doesn't apply to git13, and the sched-clock patches are the only ones which this series actually needs). Changes since the last posting: - More netfront review and cleanup - Added ability to

Hi, This is the Xen implementation for the paravirt_ops interface. The series is based on 2.6.22-rc1-mm1, and I think its ready to be cooked in -mm with a view to being merged in 2.6.23. The first part of the series is some small changes to the core kernel. Apart from the new code added in "Allocate and free vmalloc areas" (posted many times before), they are simply a few one-liners

Changes since the last posting: - reviews of xenbus (me), netfront (hch, rusty, herbert xu) and blockfront (hch), with most comments addressed. Netfront review revealed a couple of real bugs, and the code for all three is looking cleaner

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
