Re: [Xen-devel] Scheduler portability problem

Bottom line: The current code in __enter_scheduler() does not easily
accommodate other architectures. I'll be taking a look at what it
will take to "fix" it, but wanted to open discussion first. I know
there are some that will say "just change the ia64 code"... because
of architectural constraints, this is far FAR more easily said than
done. And there are some that will say that mimicking Linux is
a mistake because XINL (Xen is not Linux). However, I believe this
is a case where leveraging the many many years of experience on many
many architectures (with said experience only documented in the code
itself) of Linux will benefit Xen portability in the long run (and,
in my case, in the short run).
I've changed the tail of __enter_scheduler() to call a new
arch-specific function context_switch(). This subsumes switch_to() and
schedule_tail() so should give you the freedom to do what you require.
