hardware signal tracing, register monitoring etc.
Tracing is quite new addition, so far it's only used for development
or debugging QEMU point of view I think.
I think you are referring to hardware model debugging and logging.
The QEMU "tracing" mechanism that Blue Swirl mentioned is a
DTrace/SystemTap style tool for observing QEMU internals and not what
you are looking for.
I believe Lluís (cc'ed) has worked on using/extending the trace
framework to instrument guests.
QEMU has a built-in GDB server, so you can debug your code and inspect
registers.
The QEMU monitor is another way to inspect registers beyond those
shown in GDB.
