2 # TPM device configuration
6 tristate "TPM Hardware Support"
8 depends on EXPERIMENTAL
11 If you have a TPM security chip in your system, which
12 implements the Trusted Computing Group's specification,
13 say Yes and it will be accessible from within Linux. For
14 more information see <http://www.trustedcomputinggroup.org>.
15 An implementation of the Trusted Software Stack (TSS), the
16 userspace enablement piece of the specification, can be
17 obtained at: <http://sourceforge.net/projects/trousers>. To
18 compile this driver as a module, choose M here; the module
19 will be called tpm. If unsure, say N.
21 1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI
23 2) Without ACPI enabled, the BIOS event log won't be accessible,
24 which is required to validate the PCR 0-7 values.
29 tristate "TPM Interface Specification 1.2 Interface"
32 If you have a TPM security chip that is compliant with the
33 TCG TIS 1.2 TPM specification say Yes and it will be accessible
34 from within Linux. To compile this driver as a module, choose
35 M here; the module will be called tpm_tis.
38 tristate "National Semiconductor TPM Interface"
41 If you have a TPM security chip from National Semiconductor
42 say Yes and it will be accessible from within Linux. To
43 compile this driver as a module, choose M here; the module
44 will be called tpm_nsc.
47 tristate "Atmel TPM Interface"
48 depends on PPC64 || HAS_IOPORT
50 If you have a TPM security chip from Atmel say Yes and it
51 will be accessible from within Linux. To compile this driver
52 as a module, choose M here; the module will be called tpm_atmel.
55 tristate "Infineon Technologies TPM Interface"
58 If you have a TPM security chip from Infineon Technologies
59 (either SLD 9630 TT 1.1 or SLB 9635 TT 1.2) say Yes and it
60 will be accessible from within Linux.
61 To compile this driver as a module, choose M here; the module
62 will be called tpm_infineon.
