| 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 <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. |
