For 13 more information see <http://www.trustedcomputinggroup.org>. 14 An implementation of the Trusted Software Stack (TSS), the 15 userspace enablement piece of the specification, can be 16 obtained at: <http://sourceforge.net/projects/trousers>. To 17 compile this driver as a module, choose M here; the module 18 will be called tpm. If unsure, say N. 19 Notes: 20 1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI 21 and CONFIG_PNPACPI. 22 2) Without ACPI enabled, the BIOS event log won't be accessible, 23 which is required to validate the PCR 0-7 values. 24 25if TCG_TPM 26 27config TCG_TIS 28 tristate "TPM Interface Specification 1.2 Interface / TPM 2.0 FIFO Interface" 29 depends on X86 30 ---help--- 31 If you have a TPM security chip that is compliant with the 32 TCG TIS 1.2 TPM specification (TPM1.2) or the TCG PTP FIFO 33 specification (TPM2.0) say Yes and it will be accessible from 34 within Linux.
