From 9fbdd7c4fb0bd5c81d294f283317bc3156242ddc Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Mon, 6 Jun 2011 22:47:05 +0300 Subject: [PATCH] kvm tools: Kill libvnc dependency from hw/i8042.c This patch kills the libvnc dependency from hw/i8042.c so we can use the same hardware driver for SDL UI.
