Subject: [PATCH 09/14] OvmfPkg: Add MaxAcceptedMemoryAddress in TDX work area
Date: Mon, 6 Jun 2022 10:59:57 +0800 [thread overview]
Message-ID: <fb95c35d886ccacf2eadfba27aefd5618b3f00ec.1654420876.git.min.m.xu@intel.com> (raw)
In-Reply-To: <cover.1654420875.git.min.m.xu@intel.com>
From: Min M Xu <min.m.xu@intel.com>
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3937
In lazy-accept the MaxAcceptedMemoryAddress is needed in
TransferTdxHobList and ContructFwHobList(at PeilessStartupLib). But in
SEC phase we cannot use a global variable to pass this value. So we add
a new field (MaxAcceptedMemoryAddress) in Tdx work area.
