Now that the environment (libxc, xen-ia64) is ready to start a simple BE domU, I want to start a new discussion about BE able mini-os. What I want to have is a mini-os, where everybody whith ia64 hardware can build and run a BE mini-os beside LE mini-os (or other domU's) on xen-ia64 hypervisor. If you say at this point: no interrest for such a thing, than we can stop this discussion here. On the other side we should discuss how this can be realized. My target with the first patch was to minimize the impact on common mini-os source as small as possible and that the hypervisor shouldn't be touched by BE/LE problematic. Therewidth I did only the SWAPs at the right place in the mini-os. Maybe that SWAPs are ugly but the SWAPs have to be done somewhere and the best place in my opinion is in the domU at the lowest level functions on top of the hypervisor interface - in gnttab, xenbus, xencons, event. The other way would be building wrappers around all the accesses to domU/hypervisor interfaces and hide the SWAPs there. But this seems a little bit overkill at this stage. Oh and yes I will care about this in the mini-os! Thanks.
