Raw Normal View History

Linux-2.6.12-rc2 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!

tpm: redefine read_log() to handle ACPI/OF at runtime Currently, read_log() has two implementations: one for ACPI platforms and the other for device tree(OF) based platforms. The proper one is selected at compile time using Kconfig and #ifdef in the Makefile, which is not the recommended approach. This patch removes the #ifdef in the Makefile by defining a single read_log() method, which checks for ACPI/OF event log properties at runtime.

tpm: expose spaces via a device link /dev/tpmrm<n> Currently the tpm spaces are not exposed to userspace. Make this exposure via a separate device, which can now be opened multiple times because each read/write transaction goes separately via the space. Concurrency is protected by the chip->tpm_mutex for each read/write transaction separately. The TPM is cleared of all transient objects by the time the mutex is dropped, so there should be no interference between the kernel and userspace.

tpm/tpm_tis: Split tpm_tis driver into a core and TCG TIS compliant phy To avoid code duplication between the old tpm_tis and the new and future native tcg tis driver(ie: spi, i2c...), the tpm_tis driver was reworked, so that all common logic is extracted and can be reused from all drivers. The core methods can also be used from other TIS like drivers. itpm workaround is now managed with a specific tis flag TPM_TIS_ITPM_POSSIBLE. This commit is based on the initial work by Peter Huewe.

char/tpm: Add new driver for Infineon I2C TIS TPM This patch adds a driver to support Infineon's SLB 9635 TT 1.2 Soft I2C TPMs which follow the TGC TIS 1.2 TPM specification[1] and Infineon's I2C Protocol Stack Specification 0.20. The I2C Protocol Stack Specification is a simple adaption of the LPC TIS Protocol to the I2C Bus. The I2C TPMs can be used when LPC Bus is not available (i.e. non x86 architectures like ARM). The driver is based on the tpm_tis.c driver by Leendert van Dorn and Kyleen Hall and has quite similar functionality. Tested on Nvidia ARM Tegra2 Development Platform and Beagleboard (ARM OMAP) Tested with the Trousers[2] TSS API Testsuite v 0.3 [3] Compile-tested on x86 (32/64-bit) Updates since version 2.1.4: - included "Lock the I2C adapter for a sequence of requests", by Bryan Freed - use __i2c_transfer instead of own implementation of unlocked i2c_transfer - use struct dev_pm_ops for power management via SIMPLE_DEV_PM_OPS Updates since version 2.1.3: - use proper probing mechanism * either add the tpm using I2C_BOARD_INFO to your board file or probe it * during runtime e.g on BeagleBoard using : * "echo tpm_i2c_infineon 0x20 > /sys/bus/i2c/devices/i2c-2/new_device" - fix possible endless loop if hardware misbehaves - improved return codes - consistent spelling i2c/tpm -> I2C/TPM - remove hardcoded sleep values and msleep usage - removed debug statements - added check for I2C functionality - renaming to tpm_i2c_infineon Updates since version 2.1.2: - added sysfs entries for duration and timeouts - updated to new tpm_do_selftest Updates since version 2.1.0: - improved error handling - implemented workarounds needed by the tpm - fixed typos References: [1] http://www.trustedcomputinggroup.org/resources/pc_client_work_group_pc_client_ specific_tpm_interface_specification_tis_version_12/ [2] http://trousers.sourceforge.net/ [3] http://sourceforge.net/projects/trousers/files/TSS%20API%20test%20suite/0.3/ Reviewed-by: Andi Shyti <andi.shyti@gmail.com> Acked-by: Marcel Selhorst <tpmdd@selhorst.net> Signed-off-by: Peter Huewe <peter.huewe@infineon.com> Signed-off-by: Bryan Freed <bfreed@chromium.org> Signed-off-by: Kent Yoder <key@linux.vnet.ibm.com>

[PATCH] tpm: Support for Infineon TPM 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].

drivers/char/tpm: Add new device driver to support IBM vTPM This patch adds a new device driver to support IBM virtual TPM (vTPM) for PPC64. IBM vTPM is supported through the adjunct partition with firmware release 740 or higher. With vTPM support, each lpar is able to have its own vTPM without the physical TPM hardware. This driver provides TPM functionalities by communicating with the vTPM adjunct partition through Hypervisor calls (Hcalls) and Command/Response Queue (CRQ) commands.

tpm: TPM 2.0 CRB Interface tpm_crb is a driver for TPM 2.0 Command Response Buffer (CRB) Interface as defined in PC Client Platform TPM Profile (PTP) Specification. Only polling and single locality is supported as these are the limitations of the available hardware, Platform Trust Techonlogy (PTT) in Haswell CPUs. The driver always applies CRB with ACPI start because PTT reports using only ACPI start as start method but as a result of my testing it requires also CRB start.

tpm: Proxy driver for supporting multiple emulated TPMs This patch implements a proxy driver for supporting multiple emulated TPMs in a system. The driver implements a device /dev/vtpmx that is used to created a client device pair /dev/tpmX (e.g., /dev/tpm10) and a server side that is accessed using a file descriptor returned by an ioctl. The device /dev/tpmX is the usual TPM device created by the core TPM driver. Applications or kernel subsystems can send TPM commands to it and the corresponding server-side file descriptor receives these commands and delivers them to an emulated TPM. The driver retrievs the TPM 1.2 durations and timeouts. Since this requires the startup of the TPM, we send a startup for TPM 1.2 as well as TPM 2.
