Subject: [edk2-devel] [PATCH v2 6/6] uefi-sct/SctPkg: TCG MORLOCK Locked with Key State Test
Date: Tue, 22 Aug 2023 21:09:47 -0500 [thread overview]
Message-ID: <20230823020947.124395-7-Abhi.Singh@arm.com> (raw)
In-Reply-To: <20230823020947.124395-1-Abhi.Singh@arm.com>
SCT spec: https://bugzilla.tianocore.org/show_bug.cgi?id=4374
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4419
-Implement MemoryOverwriteRequestControlLock Locked with
Key State test cases
-Add remaining Assertions 33 - 49 from SCT spec
-Add Test Case to MemoryOverwriteRequestFunctionTest
