Hi, I was wondering if there is any documentation on how to write a bare metal application for Xen. I don''t need to parse the device tree and such yet, a simple booting "Hello World" would be fine :-) We wrote one and when trying to boot we get ( this was an uncompressed binary, no image): libxl: notice: libxl_numa.c:451:libxl__get_numa_candidate: NUMA placement failed,

I''ve addressed all (I think/hope) of the review comments. The main change is to expose the guest virtual platform (e.g. memory layout and interrupt usage etc) to the toolstack via the public interface. This is then used during FDT generation. I have just codified the current defacto standard layout, it''s probably not the best layout but any change can be a separate patch/series.

Biggest change is to switch the new DTB node to /xen-core-devices instead of /xen at Stefano''s request. I also dropped the few patches title HACK etc which weren''t supposed to be there and fixed up some bits and pieces which folks commented on. George, WRT the freeze I think this is functionality which we cannot ship Xen 4.4 without. The impact is entirely constrained to the

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 -
