In particular we want to avoid the timers initialization so that Qemu doesn't need to wake up needlessly. Signed-off-by: Stefano Stabellini<stefano.stabellini@xxxxxxxxxxxxx>Yuck. There's got to be a better way to do this.Yeah, it is pretty ugly, I was hoping in some good suggestions to improve this patch :)I think it would be better to name timers and then in Xen specific machine code, disable the RTC timers.Good idea! I was thinking that I could implement an rtc_stop function in mc146818rtc.c that stops and frees the timers. You could also just stop the rtc_clock. The rtc is the only device that makes use of the rtc_clock.
