Subject: [PATCH v2 0/3] tpm: Preserve TPM measurement log across kexec
Date: Thu, 16 Jun 2022 11:41:27 -0400 [thread overview]
Message-ID: <20220616154130.2052541-1-stefanb@linux.ibm.com> (raw)
The of-tree driver does not currently preserve the IBM vTPM 1.2 and
vTPM 2.0 measurement logs across a kexec. This series fixes this for the
kexec_file_load() syscall using the flattened device tree (fdt) to
carry the measurement log's buffer across kexec.
Stefan
v2:
- rearranged patches
- fixed compilation issues for x86
Stefan Berger (3):
tpm: of: Move of-tree specific code from tpm driver into of driver
of: kexec: Refactor IMA buffer related functions to make them reusable
tpm/kexec: Duplicate TPM measurement log in of-tree for kexec
