If you have a TPM security chip in your system, which implements the Trusted Computing Group's specification, say Yes and it will be accessible from within Linux. For more information see <http://www.trustedcomputinggroup.org>. An implementation of the Trusted Software Stack (TSS), the userspace enablement piece of the specification, can be obtained at: <http://sourceforge.net/projects/trousers>. To compile this driver as a module, choose M here; the module will be called tpm. If unsure, say N. Notes: 1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI and CONFIG_PNPACPI. 2) Without ACPI enabled, the BIOS event log won't be accessible, which is required to validate the PCR 0-7 values.
If you have a TPM security chip that is compliant with the TCG TIS 1.2 TPM specification say Yes and it will be accessible from within Linux. To compile this driver as a module, choose M here; the module will be called tpm_tis.
If you have a TPM security chip from National Semiconductor say Yes and it will be accessible from within Linux. To compile this driver as a module, choose M here; the module will be called tpm_nsc.
If you have a TPM security chip from Atmel say Yes and it will be accessible from within Linux. To compile this driver as a module, choose M here; the module will be called tpm_atmel.
If you have a TPM security chip from Infineon Technologies (either SLD 9630 TT 1.1 or SLB 9635 TT 1.2) say Yes and it will be accessible from within Linux. To compile this driver as a module, choose M here; the module will be called tpm_infineon. Further information on this driver and the supported hardware can be found at http://www.trust.rub.de/projects/linux-device-driver-infineon-tpm/
