# # TPM device configuration # menuconfig TCG_TPM tristate "TPM Hardware Support" depends on HAS_IOMEM select SECURITYFS ---help--- 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 . An implementation of the Trusted Software Stack (TSS), the userspace enablement piece of the specification, can be obtained at: . 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 TCG_TPM config TCG_TIS_CORE tristate ---help--- TCG TIS TPM core driver.
