[edk2-devel] [PATCH v3 0/3] TCG_Sp800_155_PlatformId_Event3 support

[edk2-devel] [PATCH v3 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 v2:
  - Removed errant spacing.
Changes since v1:
  - MdePkg defines TCG_Sp800_155_PlatformId_Event3 instead of adding a
    comment about Event3 to Event2.

Re: [edk2-devel] [PATCH v3 0/3] TCG_Sp800_155_PlatformId_Event3 support

[Yao, Jiewen]

Hi Dionna
I tried to create PR but I saw failure - https://github.com/tianocore/edk2/pull/5628

Would you please clarify if you have tested the patch in EDKII CI, before you submit the patch?


BTW: I have fixed a typo in the V3 patch. The "Reviewed-By" tag in 1/3 should be "Reviewed-by".

Thank you
Yao, Jiewen

Re: [edk2-devel] [PATCH v3 0/3] TCG_Sp800_155_PlatformId_Event3 support

[Dionna Glaze via groups.io]

I had not passed some tests, apologies. I fixed the spacing issue and
build failure with too many )s in
https://github.com/tianocore/edk2/pull/5615. Shall I email a v4?
