Hi all, This is a trivial patch which adds the two fields to start_info_t for the shared page and event channel port for the share. Feel free to destroy this in any way. The python binding just fills zeros in for the moment, making it harmless. Mike Wray has a nicer version in his tree, but this is the minimal version. (Thanks to Mike for the .esp fix, too). Cheers,...

Hi Gregor, on ia64 the start_info_t pointer is stored within shared_info_t structure. So it makes sense to initialize the pointer within arch_init(), which is different from x86. With this patch the &si is given to arch_init(). Please have a look! Thanks. Dietmar. _______________________________________________ Xen-devel maili...

I last posted this back in April to critical acclaim (AKA near total silence). I''m not sure who looks after tools/include/xen-foreign. I had thought it was Jan but I think I was confused and was thinking of the semi-related xen/include/compat stuff. IOW I think nobody felt "responsible". Unless there''s any objection lets just treat this as coming under tools. The

This patch series contains a set of patches making minios rather easier to use, from an application development point of view. Overview of patches: 1 Command line argument parsing support, from Xen. 2 Weak console handler function. 3 Build system tweaks for application directories. 4 Trailing whitespace cleanup. (because it is very messy) Patch 4 is likely to be more controversial than

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -

This patch series implements the Linux Xen guest in terms of the paravirt-ops interface. The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen console * virtual block
