Without I/O signals, qemu is relying on periodic timer events to poll
the I/O.
I wonder if this patch makes sense, using SIGALRM for all kinds of
timers, even those expiring through a file descriptor?
It seems more clean to me to always use SIGALRM for alarms, but the
actual trigger for this change was to free up SIGIO for KVM.
Unfortunately, I have been unable to test it m

That is great, thanks. However, I ha
Hello.
This patch stops the qemu seconds timer when the RTC is not used. Once
the cmos is accessed, the skipped seconds are accounted for, and the
timer is enabled again.
In case interrupts are to be delivered, the timer is not disabled.
I have obviously gone mad from staring too much at PowerT
