Hi,
We are trying to do a simple save/restore on the VM with icount enabled.
We saw that qemu_icount_bias and qemu_icount in cpus.c are not
saved/restored,
and icount_extra, icount_decr in CPUState neither, so the vm_clock is just
growing normally after restoring the VM is that normal?
We think that this is making the "replay" undeterminastic, which is bad for
reverse execution.
Is there a good reason for them not being saved?
Thanks,
Fred
