From 4e7fa73ec2516334b58e82f9a5649b1468b1eb7a Mon Sep 17 00:00:00 2001 From: Pavel Dovgalyuk Date: Wed, 26 Nov 2014 13:40:50 +0300 Subject: timer: introduce new QEMU_CLOCK_VIRTUAL_RT clock This patch introduces new QEMU_CLOCK_VIRTUAL_RT clock, which should be used for icount warping. In the next patch, it will be used to avoid a huge icount warp when a virtual machine is stopped for a long time.
