Subject: [PATCH V2 2/3] SecurityPkg: Support TdProtocol in DxeTpm2MeasureBootLib
Date: Fri, 8 Oct 2021 13:21:13 +0800 [thread overview]
Message-ID: <09c7d8dd1c1856d8d0295064c8b833dd3d85e8c4.1633661591.git.min.m.xu@intel.com> (raw)
In-Reply-To: <cover.1633661591.git.min.m.xu@intel.com>
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3625
DxeTpm2MeasureBootLib supports TPM2 based measure boot. After
Td protocol is introduced, TD based measure boot needs to be supported
in DxeTpm2MeasureBootLib as well.
There are 2 major changes in this commit.
1. MEASURE_BOOT_PROTOCOLS is defined to store the instances of TCG2
protocol and TD protocol. In the DxeTpm2MeasureBootHandler above 2
measure boot protocol instances will be located. Then the located
protocol instances will be called to do the measure boot.
2. TdEvent is similar to Tcg2Event except the MrIndex and PcrIndex.
CreateTdEventFromTcg2Event is used to create the TdEvent based on the
Tcg2Event.
Above 2 changes make the minimize changes to the existing code.
