Subject: [PATCH v3 0/3] tpm: Preserve TPM measurement log across kexec (ppc64)
Date: Tue, 28 Jun 2022 12:58:17 -0400	[thread overview]
Message-ID: <20220628165820.883222-1-stefanb@linux.ibm.com> (raw)

The of-tree subsystem does not currently preserve the IBM vTPM 1.2 and
vTPM 2.0 measurement logs across a kexec on ppc64. 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.
