No. What I do is using gen_helper_ to compile hooks into call/ret/jmp and
memory access. The Heuristics can then hook the events so calculation is
done during the execution of a basic block. I thought that it could be
possible that Qemu sets a timeout for BBL execution to prevent CPU
monopolization by e.g. a long sequence of rep. That would make sense because
my heuristics calculation time falls into the BBL execution time for Qemu.
Does anyone know more about that?
perhaps your heuristics code somehow coincide with the timer alarm
(PIT, HPET etc) emulation in Qemu....and somewhere your code is not
reentrant.....
