Subject: [PATCH v8 0/2] tpm2: Make TPM2 logs accessible for non-UEFI firmware
Date: Fri, 26 Jun 2020 11:39:46 -0400
Message-ID: <20200626153948.2059251-1-stefanb@linux.vnet.ibm.com> (raw)

From: Stefan Berger <stefanb@linux.ibm.com>

This series of patches adds an optional extensions for the TPM2 ACPI table
with additional fields found in the TPM2 TCG ACPI specification (reference
is in the patch) that allow access to the log's address and its size. We
then modify the code that so far only enables access to a TPM 1.2's log for
a TPM2 as well. This then enables access to the TPM2's log on non-UEFI
system that for example run SeaBIOS.

v7->v8:
 - Added empty line.

v6->v7:
 - Added empty lines and R-b.

v5->v6:
 - Moved extensions of TPM2 table into acpi_tpm2_phy.

v4->v5:
 - Added R-bs and A-bs.

v3->v4:
  - Repost as one series

v2->v3:
  - Split the series into two separate patches
  - Added comments to ACPI table fields
  - Added check for null pointer to log area and zero log size

v1->v2:
  - Repost of the series
