Hi Imran,

I gave a try to the tpm2_eventlog tool.

If I try to read the binary_bios_measurements log directly, it fails.

[root(a)localhost misc]# ./tpm2_eventlog /sys/kernel/security/tpm0/binary_bios_measurements 
---
ERROR: insufficient size for SpecID event header
ERROR: failed to parse tpm2 eventlog
ERROR: Unable to run ./tpm2_eventlog

But if I copy the event log to a local file, it works :)

[root(a)localhost misc]# cp /sys/kernel/security/tpm0/binary_bios_measurements .
[root(a)localhost misc]# ./tpm2_eventlog binary_bios_measurements 

I understand that the /sys/kernel/security/tpm0/binary_bios_measurements is not a regular file, but is this expected?

Thank you
