Subject: [PATCH 0/3] tpm: Preserve TPM measurement log across kexec
Date: Tue, 14 Jun 2022 12:12:55 -0400	[thread overview]
Message-ID: <20220614161258.1741427-1-stefanb@linux.ibm.com> (raw)

The current of-tree driver does not currently preserve the vTPM 1.2 and
vTPM 2.0 measurement log 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.
