Subject: TPM 2.0 ACPI tableTPM2 table event log

Hi Chao and Jiewen,

There are new fields in TPM2 ACPI table for getting TCG event log under OS.

https://trustedcomputinggroup.org/wp-content/uploads/TCG_ACPIGeneralSpecification_v1.20_r8.pdf
Page 11.
Log Area Minimum Length (LAML)
Log Area Start Address (LASA)

I remember they are not existed in older TCG ACPI spec.

Do you have plan to implement it?

Thanks,
Derek
