[edk2-devel] [PATCH v2 0/3] TCG_Sp800_155_PlatformId_Event3 support

[edk2-devel] [PATCH v2 0/3] TCG_Sp800_155_PlatformId_Event3 support

[Dionna Glaze via groups.io]

In December 2023, the TCG published the PC Client Platform Firmware
Profile version 1.06 revision 52. This revision includes a new event
type for NIST SP 800-155 recommended signed BIOS reference measurements.
The new type allows for the event log auditor to find local or remote
copies of the signed reference measurements.

Supporting this new event type eases the process of distributing signed
reference measurements since the machine can now simply report where
they can be found in a standard way.

Changes since v1:
  - MdePkg defines TCG_Sp800_155_PlatformId_Event3 instead of adding a
    comment about Event3 to Event2.

Re: [edk2-devel] [PATCH v2 1/3] MdePkg: Add TcgSp800155Event3 type info

[Yao, Jiewen]

Thanks Dionna.

Almost good, except you create a typo below:
>    EFI_GUID    ReferenceManifestGuid;
> -  //
> +   //
>    // Below structure is newly added in TCG_Sp800_155_PlatformId_Event2.

With typo fix, reviewed-by: Jiewen Yao <Jiewen.yao@intel.com>

Thank you
Yao, Jiewen
