Xen devel - Feb 2006 - [RFC] SMP & DEBUG config options

Lately a lot of the Xen problems we have run into are related
to bugs that only trigger when using the DEBUG config options
and/or SMP.

I wonder if it would make sense to have those enabled in the
default install, so developers can notice bugs in their own
code before it gets committed and shipped off to dozens of
other developers elsewhere - who then have to spend days
trying to track down which changeset caused the problem...

Is there any good reason that the DEBUG config options and
SMP are not enabled in the default configuration?

Certainly sounds sensible to me.  The x86_64 xen_unstable.hg didn''t
even
boot an SMP dom0 until the module-faulting changes went in today; that
sort of thing really could do with having more exposure.

Fedora/rawhide is currently shipping only SMP kernels for x86_64 and
that''s working pretty well.  (We still have UP kernels as an option for
i386, though.)
