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" 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 say Yes and it will be accessible 33 from within Linux.
