From: Stefan Berger <stefanb@xxxxxxxxxxxxx> This series of patches extends the existing 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. Stefan v1->v2: - Repost of the series Stefan Berger (3): acpi: Extend TPM2 ACPI table with missing log fields tpm: Rearrange ACPI log code to easier extend for TPM2 case tpm: Add support for ACPI logs from TPM2 ACPI table drivers/char/tpm/eventlog/acpi.c | 54 ++++++++++++++++++++++++---------------- drivers/char/tpm/tpm_crb.c | 13 +++++++--- drivers/char/tpm/tpm_tis.c | 4 ++- include/acpi/actbl3.h | 5 ++-- 4 files changed, 49 insertions(+), 27 deletions(-) -- 2.14.5
