Re: [coreboot] Tianocore and TPM

Hi Ben!

Thanks for the info! I have one question. Have I to implement a CustomizationSample/Boards for my board? With the current

tianocore payload I don't have to implement nothing to have a working UEFI...

Thanks!

Jorge

Hi,

Another note is on the use of NULL|UefiPayloadPkg/Library/Tpm2InstanceLib/Tpm2InstanceLib.inf. This lib is not fully populated right now.

Please consider using  NULL|SecurityPkg/Library/Tpm2DeviceLibDTpm/Tpm2InstanceLibDTpm.inf depending on your needs.

Thanks,

Hi Jorge,

The staging UEFI Payload project (https://github.com/tianocore/edk2-staging/tree/UEFIPayload) has TPM support (although turned off by default, and using "FTPM" as the name (which needs to be fixed)).

Please have a look at UefiPayloadPkgIA32X64.dsc for the components under tag "$(FTPM_ENABLE)". These components mainly do the measuring of firmware components and log the results.

Also there is parsing logic in Library/PlatformInfoParseLib/ParseLib.c that parses TPM info in ACPI table passed from Coreboot. (This logic hasn't been sufficiently verified as this is still a "staging" project).

You might have a try. Please let us know if you see any bugs / problems in these. You might also use the EDKII mailing list for discussing issues with the UEFI Payload.

Thanks,

Hi all!

I'm trying to enable the TPM2 support in the tianocore payload. The TPM2 device is working, because I've enabled the DEBUG_TPM and coreboot reports is up. I guess that I have to modify the 'CorebootPayloadPkgIa32X64.dsc' file to enable the TPM support but there are so many dependencies. Anybody has a working tianocore payload with TPM?

Thanks!
