2016-06-25tpm: Get rid of devnameJason Gunthorpe1-1/+1
Now that we have a proper struct device just use dev_name() to access this value instead of keeping two copies.

2016-02-20tpm_eventlog.c: fix binary_bios_measurementsHarald Hoyer1-4/+10
The commit 0cc698af36ff ("vTPM: support little endian guests") copied the event, but without the event data, did an endian conversion on the size and tried to output the event data from the copied version, which has only have one byte of the data, resulting in garbage event data. [jarkko.sakkinen@linux.intel.com: fixed minor coding style issues and renamed the local variable tempPtr as temp_ptr now that there is an excuse to do this.] Signed-off-by: Harald Hoyer <harald@redhat.com> Fixes: 0cc698af36ff ("vTPM: support little endian guests") Reviewed-by: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com> cc: stable@vger.kernel.org
2015-10-19vTPM: support little endian guestsHon Ching \(Vicky\) Lo1-22/+56
This patch makes the code endianness independent. We defined a macro do_endian_conversion to apply endianness to raw integers in the event entries so that they will be displayed properly. tpm_binary_bios_measurements_show() is modified for the display.

2014-07-29tpm: simplify code by using %*phN specifierAndy Shevchenko1-3/+1
Instead of looping by ourselves we may use %*phN specifier to dump a small buffer.

2013-10-22tpm: Merge the tpm-bios module with tpm.oJason Gunthorpe1-3/+0
Now that we can have multiple .c files in the tpm module there is no reason for tpm-bios. tpm-bios exported several functions: tpm_bios_log_setup, tpm_bios_log_teardown, tpm_add_ppi, and tpm_remove_ppi. They are only used by tpm, and if tpm-bios is built then tpm will unconditionally require them. Further, tpm-bios does nothing on its own, it has no module_init function. Thus we remove the exports and merge the modules to simplify things. The Makefile conditions are changed slightly to match the code, tpm_ppi is always required if CONFIG_ACPI is set.

2012-08-22tpm: modularize event log collectionKent Yoder1-0/+419
Break ACPI-specific pieces of the event log handling into their own file and create tpm_eventlog.[ch] to store common event log handling code. This will be required to integrate future event log sources on platforms without ACPI tables. Signed-off-by: Kent Yoder <key@linux.vnet.ibm.com>
