Unlike the device driver support for TPM 1.2, the TPM 2.0 does
not support the securityfs pseudo files for displaying the

This patch enables support for providing the TPM 2.0 event log in
binary form. TPM 2.0 event log supports a crypto agile format that
records multiple digests, which is different from TPM 1.2. This
patch enables the tpm_bios_log_setup for TPM 2.0 and adds the
event log parser which understand the TPM 2.0 crypto agile format.

I don't want to say much about this before I've tested it. I wonder
what cheap hardware I could use to test this. Any advice is on this
from anyone is much appreciated.
Virtual hardware would be cheap :-)
I tested this series with QEMU + vTPM + SeaBIOS with TPM 1.2 + TPM 2
support (basing the log on ACPI). I had to fix an endianess issue on the
SeaBIOS side, which made it work. So for this version of the patches I
can give it my tested-by:
