Re: [Qemu-devel] [4432] Debugger single step without interrupts (Jason Wessel).

[Fabrice Bellard <fabrice@bellard.org>]

I see no reason why the real time timers should be stopped while single
stepping. These timers have no relation with the emulation.

BTW, it seems that some devices incorrectly use the real time timers...

Regards,

Fabrice.
