It now calls exit(1). Due to a change in the TPM 2 code, the pcrUpdateCounter (14th byte) in the TPM2_Pcrread response now returns a different value than before. So it's better to skip the 14th byte when comparing expected against actual responses. Stefan v1->v2: - simplified skipping of 14th byte in response Stefan Berger (2): tpm: tpm_spapr: Exit on TPM backend failures tests: Skip over pcrUpdateCounter byte in result comparison hw/tpm/tpm_spapr.c | 5 ++++- tests/qtest/tpm-util.c | 6 +++++- 2 files changed, 9 insertions(+), 2 deletions(-)
