Re: [Xen-devel] 32/64-bit hypercall interface
You also said you would never support PAE. PAE is second-only to SMP
support on the list of customer requirements. There may be a compelling
reason not to, but superficially running many 32-bit paravirtualized
guests on a 64-bit HV makes a great deal of sense.

There's the rub: we don't expect to ever want to provide 32-bit x86 ABI
compatibility on 64-bit x86 Xen. We will not be supporting 32-bit
paravirtualised guests on 64-bit x86 Xen, and we've taken the approach
of requiring separate 32- and 64-bit toolsets (which isn't too painful
on x86 since full-fledged 64-bit filesystems are quite easy to come
by).
Really this sounds to me like this is only going to be a problem for
ppc. That given, knocking up a translation script to import the
interfaces into your 32-bit toolchain does seem worthy of
consideration. It wouldn't allow you to use the same tool binaries on
both 32- and 64-bit ppc Xen, but I don't know how much you actually
care about that...
