[PATCH] tpm_infineon: Support for new TPM 1.2 and PNPACPI

2005-08-05T19:22:37+00:00

This patch includes support for the new Infineon Trusted Platform Module
SLB 9635 TT 1.2 and does further include ACPI-support for both chip
versions (SLD 9630 TT 1.1 and SLB9635 TT 1.2).  Since the ioports and
configuration registers are not correctly set on some machines, the
configuration is now done via PNPACPI, which reads out the correct values
out of the DSDT-table.  Note that you have to have CONFIG_PNP,
CONFIG_ACPI_BUS and CONFIG_PNPACPI enabled to run this driver (assuming
that mainboards including a TPM do have the need for ACPI anyway).

[PATCH] ppc64: tpm_infineon build fix

2005-07-27T23:26:07+00:00

ppc64 uses symbol `DAR', as does the TPM driver, causing a build failure.
Change the TPM name.

[PATCH] tpm: Support for Infineon TPM

2005-07-27T23:26:06+00:00

This patch provides a new device driver for the Infineon SLD 9630 TT Trusted
Platform Module (TPM 1.1b) [1] which is embedded on Intel- mainboards or in
HP/ Fujitsu-Siemens / Toshiba-Notebooks.  A nearly complete list where this
module is integrated in can be found in [2].

This kernel module acts as a communication gateway between the linux kernel
and the hardware chip and fits the TPM-specific interfaces created by IBM in
drivers/char/tpm/tpm.h

Further information about this module and a list of succesfully tested and
therefore supported hardware can be found at our project page [3].

[PATCH] tpm: fix bug introduced by the /proc/misc

2005-06-30T15:45:09+00:00

In fixing the /proc/misc problem that was reported last week where the tpm
module name was being obfuscated in /proc/misc I introduced a bug in the
module unloading code.  This patch fixes the problem.

[PATCH] tpm: fix misc name memory problem

2005-06-25T23:24:38+00:00

I was using invalid memory for the miscdevice.name.  This patch fixes the
problem which was manifested by an ugly entry in /proc/misc.

[PATCH] tpm: Support new National TPMs

2005-06-25T23:24:38+00:00

This patch is work to support new National TPMs that problems were reported
with on Thinkpad T43 and Thinkcentre S51.  Thanks to Jens and Gang for
their debugging work on these issues.

[PATCH] tpm: improve output in sysfs files when the TPM fails

2005-06-24T07:05:27+00:00

Since after reconsideration this is more debug output than an error (the
TPM is operating correctly given the current state) I have changed the
statements to dbg rather than err.

Also this patch corrects a memory leak if the error path is taken in the
tpm_show_pubek function.

[PATCH] tpm: replace odd LPC init function

2005-06-24T07:05:27+00:00

Realized the tpm_lpc_init function isn't really necessary.  Replaced it
with vendor specific logic to find out the address the BIOS mapped the TPM
to.  This patch removes the tpm_lpc_init function, enums associated with it
and calls to it.  The patch also implements the replacement functionality.
