...ging TSC speeds (informing all the guests about the TSC impending change before it happens would be a great deal of code and have issues with disobedient guests). This patch makes the host determine if the TSC is both constant and stable: if not, it doesn't tell the guest to use it. We export check_tsc_unstable() for this.

I''ve uploaded updated 2.6.31 and 2.6.32 rebased openSUSE Xen dom0 patches and ebuilds to http://code.google.com/p/gentoo-xen-kernel/downloads/list Notable change is that both include the online resize feature recently posted to xen-devel.

Hello, This series of patches integrates msr.h header. What it really does, is a series of steps to allow us to get rid of duplicate code between i386 and x86_64 versions With this done, achieving paravirt for x86_64 gets really easy, just a couple of extra code. The first patch was already sent a while ago, but was not yet pushed to any tree , to my knowledge. So it is sent again. Also,

Hi all, I've been working on lguest64 and in order to do this, I had to move a lot of the i386 specific out of the way. Well, the lguest64 port is still not ready to display, but before Rusty makes too many changes I would like this in upstream so I don't have to keep repeating my changes :-) So this patch series moves lguest32 out of the way for other archs. -- Steve

[ Changes since last version. - Move lg.h to include/asm instead (suggested by Rusty Russel) - All steps of the series compiles (suggested by Stephen Rothwell) - Better ifdef header naming (suggested by Stephen Rothwell) - Added Andi Kleen to CC (forgot to on V1) ] Hi all, I've been working on lguest64 and in order to do this, I had to move a lot of the i386 specific out of the

Hi all, These are the patches I'm planning to submit for 2.6.24. Comments gratefully accepted. Along with the usual cleanups and improvements are Jes' de-i386-ification patches, and a new "virtio" mechanism designed to be shared with KVM (and hopefully other hypervisors). Cheers, Rusty.
