From 9dee7e510969787be49771e4653a123a26d1069f Mon Sep 17 00:00:00 2001 From: Xiaoyao Li Date: Thu, 10 Mar 2022 20:28:10 +0800 Subject: [PATCH] hw/i386: Make pit a property of common x86 base machine type Both pc and microvm have pit property individually. Let's just make it the property of common x86 base machine type. Signed-off-by: Xiaoyao Li Reviewed-by: Sergio Lopez Message-Id: <20220310122811.807794-2-xiaoyao.li@intel.com> Reviewed-by: Michael S.
