Date: Fri, 10 Jun 2016 18:55:02 -0700 From: Ed Swierk <eswierk@...portsystems.com> To: tpmdd-devel@...ts.sourceforge.net Cc: eswierk@...portsystems.com, stefanb@...ibm.com, jarkko.sakkinen@...ux.intel.com, linux-kernel@...r.kernel.org, linux-security-module@...r.kernel.org, jgunthorpe@...idianresearch.com Subject: [PATCH v6 0/5] tpm: Command duration logging and chip-specific override 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: Factor out 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 | 192 ++++++++++++++++++++++----------------- drivers/char/tpm/tpm_tis.c | 48 +++++----- include/linux/tpm.h | 3 +- 3 files changed, 132 insertions(+), 111 deletions(-) -- 1.9.1
