[Xen-devel] A few nits on 1.1450

[Kip Macy <kmacy@xxxxxxxxxxxxxxx>]

Xen wouldn't compile with tracing enabled:

kmacy@siml3 bk diffs include/asm/shadow.h
===== include/asm/shadow.h 1.33 vs edited =====
119,120c119
<         SH_LOG("mark_dirty OOR! mfn=%x pfn=%x max=%x (mm %p)",
<                mfn, pfn, m->shadow_dirty_bitmap_size, m );
---
>         SH_LOG("mark_dirty OOR! mfn=%x pfn=%lx max=%x (mm %p)", mfn,
pfn, m->shadow_dirty_bitmap_size, m );

=====

I've made all the changes that I believe should be necessary in order
for freebsd to be built with the generic domain builder. However, I
appear to be faulting on the very first push, do I have to do the load
far pointer that linux does at start of day in order for the stack to be
valid?

=====

To take a look around I put an "int $0x3" at the very beginning. When I
ran it, instead of dropping into the debugger, or at least printing
something on the console, DOM0 locked up. I was still able to manually
drop it into the debugger - sort of - xen is too busy telling me that
"Time went backwards" to respond to the gdb client's requests:

DOM0).
