From 16b29ae1807b024bd5052301550f5d47dae958a2 Mon Sep 17 00:00:00 2001 From: aliguori Date: Wed, 17 Dec 2008 23:28:44 +0000 Subject: Add HPET emulation to qemu (Beth Kon) This patch adds HPET emulation. It can be disabled with -disable-hpet. An hpet provides a more finely granular clocksource than otherwise available on PC. This means that latency-dependent applications (e.g. multimedia) will generally be smoother when using the HPET.
