...rge Dunlap and I) have been working over the last while on a full replacement for Xen''s shadow pagetable support. This mail contains some design notes, below; a patch against xen-unstable, giving a snapshot of the current state of the new shadow code, is at http://www.cl.cam.ac.uk/~tjd21/shadow2.patch Comments on both are welcome, although the code is not finished -- in particular there are both some optimizations and some tidying-up that need to be done. Cheers, Tim. ---- The new shadow code (dubbed ''shadow2''), is designed as a replacement for the current shadow cod...

...little odd that we''re doing a memcmp to determine which portions of the VRAM has changed. Couldn''t we just use dirty page tracking in the shadow paging code? That should significantly lower the overhead of this plus I believe the infrastructure is already mostly there in the shadow2 code. Is this a sane idea?

With pretty trivial user mode programs being able to crash the kernel due to the ref counter widths in Xen being more narrow than in Linux, I started an attempt to put together a kernel side fix. While addressing the plain hypercalls is pretty strait forward, dealing with multicalls (both when using them for lazy mmu mode batching and when explicitly using them in e.g. netback - the backends are

Am considering a new laptop, and I wonder if anyone here can share their Xen experiences with the newest Core 2 Duo CPUs, ref http://www.intel.com/products/processor/core2duo/specifications.htm The list at http://wiki.xensource.com/xenwiki/HVM_Compatible_Processors doesn''t include any Core 2 Duos. Does that mean that people have had problems, or is the wiki just not up to date? I gather

Thanks for the reply, Besides the problem with source4/lib/messaging/messaging_handlers.c, Good to hear that selftest is actively used, then do I understand it right that 'make test' should succeed? My bigger problem is that it failed with lots of errors. This must be a problem with my build, then, but since this is a fresh tarball I am a bit puzzled. I would appreciate some hint on
