Message-Id: <1468426776-42762-1-git-send-email-eswierk@skyportsystems.com> Date: Wed, 13 Jul 2016 09:19:31 -0700 From: Ed Swierk <eswierk@...portsystems.com> To: tpmdd-devel@...ts.sourceforge.net, linux-kernel@...r.kernel.org, linux-security-module@...r.kernel.org Cc: jarkko.sakkinen@...ux.intel.com, jgunthorpe@...idianresearch.com, stefanb@...ibm.com, eswierk@...portsystems.com Subject: [PATCH v9 0/5] tpm: Command duration logging and chip-specific override v9: Include command duration in existing error messages rather than logging an extra debug message. Rebase onto Jarkko's tree. v8: Fix v7 goof-up in tpm_getcap(). v7: Use tpm_getcap() instead of a redundant new function. v6: Split tpm_get_cap_prop() out of tpm_get_timeouts(); always return error on TPM command failure. v5: Use msecs_to_jiffies() instead of * HZ / 1000. v4: Rework tpm_get_timeouts() to allow overriding both timeouts and durations via a single callback. This series - improves TPM command error reporting - adds optional logging of TPM command durations - allows chip-specific override of command durations as well as protocol timeouts - overrides ST19NP18 TPM command duration to avoid lockups Ed Swierk (5): tpm_tis: Improve reporting of IO errors tpm: Add optional logging of TPM command durations tpm: Clean up reading of timeout and duration capabilities tpm: Allow TPM chip drivers to override reported command durations tpm_tis: Increase ST19NP18 TPM command duration to avoid chip lockup drivers/char/tpm/tpm-interface.c | 219 ++++++++++++++++++++------------------- drivers/char/tpm/tpm_tis_core.c | 46 ++++---- include/linux/tpm.h | 3 +- 3 files changed, 136 insertions(+), 132 deletions(-) -- 1.9.1
