Once we know what subarch it is we can do a specific hypervisor call if we need to for early printing. There are weird issues like physical vs virtual that would seem to make anything more generic very difficult to get right, because the code pointed at would need to be fully pic. So as a trivial hypervisor call certainly, but I'm pretty doubtful about a function pointer. Then we can do: if (xen) blah else if (lguest) blah2 Eric _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/virtualization
