It has been hiding actual mistakes, and there are not too many changes
necessary to make things build without suppressing this warning.

Move all extern declarations into appropriate header files.
This also fixes up a few places where the caller and the definition
had different signatures.

Fix the macro so that it evaluates false if the given register context is

Rationalise debugger stuff in the tree.
Within Xen itself, remove PDB references and fold into domu_debug.
When domu_debug hits a breakpoint, it pauses all vcpus of the domain
and raises VIRQ_DEBUGGER (not VIRQ_PDB). The debugger in domain0 can
either poll pause status or bind to VIRQ_DEBUGGER. Before debugging
a breakpointed domain the debugger should issue PAUSEDOMAIN itself, or
it is not guaranteed to see paused state of the domain!
Outside Xen there's a new dir tools/debugger, containing gdb, pdb and
a new library libxendebug (used by pdb). I also think the ptrace
functions in libxc also ought to be moved out: either to libxendebug
or to a new library libxenptrace.

More descriptive 'flags' and 'id' field names for exec_domain/domain
structures seems a good idea after all. At the same time, I've renamed
the flag macros to be a bit neater and more descriptive, and more in
keeping with the style of such definitions in asm/mm.h, for example.

No direct entry to __enter_scheduler allowed. Must always pass through
softirq handler. Also domain_crash() now returns and defers
descehduling from local CPU: old behaviour is still provided by
domain_crash_synchronous().

After a fatal trap, we want to debug whatever caused the trap rather than the trap
handler. Fix things up accordingly.
Also add some documentation while I'm here.

First cut for VM86 support, based on Stephan Diestelhorst's patches. It
doesn't actually work yet -- it's possible that e.g., signal delivery is
broken.

Big rewrite of Xen->guest transition code. If we fault during the transition
then we roll back and reenable interrupts before properly handling the
fault. This means, for example, that shadow code always executes with
interrupts enabled.
|
| |
|
|
|
|
| |
Add return codes to exception handlers to indicate if a fault was fixed
up and so instruction replay ought to work.

Cleaned up debugger interface to traps.c.
