Hi Mimi,
> The kernel does not expose the crypto agile TPM 2.0 PCR banks to
> userspace like it exposes PCRs for TPM 1.2. As a result, a userspace
> application is required to read PCRs.
> This patch adds tsspcrread support for reading the TPM 2.0 PCRs.
> tsspcrread is one application included in the ibmtss package.
> Sample error messages:
> Failed to read PCRs: (tsspcrread failed: No such file or directory)
> Failed to read PCRs: (TSS_Dev_Open: Error opening /dev/tpmrm0)
> Signed-off-by: Mimi Zohar <zohar@linux.ibm.com>
