From d7a0f71d9aac33e58d39fdbe4861d440af44fa8b Mon Sep 17 00:00:00 2001 From: Victor CLEMENT Date: Fri, 29 May 2015 17:14:06 +0200 Subject: icount: print a warning if there is no more deadline in sleep=no mode While qemu is running in sleep=no mode, a warning will be printed when no timer deadline is set. As this mode is intended for getting deterministic virtual time, if no timer is set on the virtual clock this determinism is broken.
