From a0fff77e932b704b3d2ab0ad789d466cb42047ed Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Wed, 10 Aug 2011 10:34:32 +0200 Subject: lscpu: show dispatching mode A virtual guest my run in either "horiziontal" or "vertical" mode which is the mode in which the underlying hypervisor schedules the guest cpu. Since this is of interest print this in the readable output.
