Subject: [PATCH V2 4/6] MdeModulePkg/DxeIpl: Introduce PCD PcdUse5LevelPageTable
Date: Wed, 24 Jul 2019 18:00:27 +0800 [thread overview]
Message-ID: <20190724100029.252404-5-ray.ni@intel.com> (raw)
In-Reply-To: <20190724100029.252404-1-ray.ni@intel.com>
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2008
The PCD indicates if 5-Level Paging will be enabled in long mode.
5-Level Paging will not be enabled when the PCD is TRUE but CPU
doesn't support 5-Level Paging.
