Subject: [PATCH V12 36/47] MdeModulePkg: Add PcdTdxSharedBitMask
Date: Wed, 30 Mar 2022 07:46:29 +0800 [thread overview]
Message-ID: <329a8e15d9a5ca9a73e7735cd5e8cf92961d354f.1648555175.git.min.m.xu@intel.com> (raw)
In-Reply-To: <cover.1648555175.git.min.m.xu@intel.com>
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
Guest Physical Address (GPA) space in Td guest is divided into private
and shared sub-spaces, determined by the SHARED bit of GPA. This PCD
holds the shared bit mask. Its default value is 0 and it will be set
in PlatformPei driver if it is of Td guest.
