From 2ed1ebcf65edf6757d8904000889ce52cc0a9d1b Mon Sep 17 00:00:00 2001 From: Pavel Dovgalyuk Date: Fri, 27 Feb 2015 16:11:02 +0300 Subject: [PATCH] timer: replace time() with QEMU_CLOCK_HOST This patch replaces time() function calls with calls to qemu_clock_get_ns(QEMU_CLOCK_HOST). It makes such requests deterministic in record/replay mode of icount.
