2005-09-07[PATCH] tpm: fix tpm_atmel.c on ICH6Philipp Matthias Hahn1-0/+3
While installing Debian on our new IBM X41 Tablet, I tried briefly to use the built-in Atmel TPM. The Athmel TPM is also located on the LPC-bus of the ICH6. To make it work I had to apply the following patch: Signed-off-by: Philipp Matthias Hahn <pmhahn@titan.lahn.de> Acked-by: Kylene Jo Hall <kjhall@us.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-05[PATCH] tpm_infineon: Bugfix in PNPACPI-handlingMarcel Selhorst1-31/+45
This patch corrects the PNP-handling inside the tpm-driver and some minor coding style bugs. Note: the pci-device and pnp-device mixture is currently necessary, since the used "tpm"-interface requires a pci-dev in order to register the driver. This will be fixed within the next iterations.

2005-08-05[PATCH] tpm_infineon: Support for new TPM 1.2 and PNPACPIMarcel Selhorst2-44/+113
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).

2005-07-27[PATCH] tpm: Support for Infineon TPMMarcel Selhorst3-1/+479
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].

2005-06-24[PATCH] tpm: improve output in sysfs files when the TPM failsKylene Jo Hall1-4/+6
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.

2005-06-24[PATCH] tpm: replace odd LPC init functionKylene Hall4-108/+22
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.

2005-06-24[PATCH] char/tpm: use msleep(), clean-up timers,Nishanth Aravamudan3-52/+18
The TPM driver unnecessarily uses timers when it simply needs to maintain a maximum delay via time_before(). msleep() is used instead of schedule_timeout() to guarantee the task delays as expected. While compile-testing, I found a typo in the driver, using tpm_chp instead of tpm_chip. Remove the now unused timer callback function and change TPM_TIMEOUT's units to milliseconds. Patch is compile-tested.

2005-04-16Linux-2.6.12-rc2Linus Torvalds6-0/+1425
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
