RE: [Xen-devel] Mini-os on x86_64 Xen

["Puthiyaparambil, Aravindh" <aravindh.puthiyaparambil@xxxxxxxxxx>]

Yes, the event handling code is missing. I am also seeing that page
tables are not being built for x86_64. 

This takes me to a few questions about hypercalls. The i386 hypercalls
in minios seem to be working. But they are not using the hypercall_page
as in xenlinux. So when I am updating the hypercalls for x86_64 in
minios should I look into implementing a hypercall_page or should I just
use syscalls?

Thanks,
Aravindh
