2 # TPM device configuration
6 tristate "TPM Hardware Support"
10 If you have a TPM security chip in your system, which
11 implements the Trusted Computing Group's specification,
12 say Yes and it will be accessible from within Linux. 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.
20 1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI
22 2) Without ACPI enabled, the BIOS event log won't be accessible,
23 which is required to validate the PCR 0-7 values.
28 tristate "TPM Interface Specification 1.2 Interface"
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. To compile this driver as a module, choose
34 M here; the module will be called tpm_tis.
36 config TCG_TIS_I2C_INFINEON
37 tristate "TPM Interface Specification 1.2 Interface (I2C - Infineon)"
40 If you have a TPM security chip that is compliant with the
41 TCG TIS 1.2 TPM specification and Infineon's I2C Protocol Stack
42 Specification 0.20 say Yes and it will be accessible from within
44 To compile this driver as a module, choose M here; the module
45 will be called tpm_tis_i2c_infineon.
47 config TCG_TIS_I2C_NUVOTON
48 tristate "TPM Interface Specification 1.2 Interface (I2C - Nuvoton)"
51 If you have a TPM security chip with an I2C interface from
52 Nuvoton Technology Corp. say Yes and it will be accessible
54 To compile this driver as a module, choose M here; the module
55 will be called tpm_i2c_nuvoton.
58 tristate "National Semiconductor TPM Interface"
61 If you have a TPM security chip from National Semiconductor
62 say Yes and it will be accessible from within Linux. To
63 compile this driver as a module, choose M here; the module
64 will be called tpm_nsc.
67 tristate "Atmel TPM Interface"
68 depends on PPC64 || HAS_IOPORT
70 If you have a TPM security chip from Atmel say Yes and it
71 will be accessible from within Linux. To compile this driver
72 as a module, choose M here; the module will be called tpm_atmel.
75 tristate "Infineon Technologies TPM Interface"
78 If you have a TPM security chip from Infineon Technologies
79 (either SLD 9630 TT 1.1 or SLB 9635 TT 1.2) say Yes and it
80 will be accessible from within Linux.
81 To compile this driver as a module, choose M here; the module
82 will be called tpm_infineon.
83 Further information on this driver and the supported hardware
84 can be found at http://www.trust.rub.de/projects/linux-device-driver-infineon-tpm/
87 tristate "IBM VTPM Interface"
88 depends on PPC_PSERIES
90 If you have IBM virtual TPM (VTPM) support say Yes and it
91 will be accessible from within Linux. To compile this driver
92 as a module, choose M here; the module will be called tpm_ibmvtpm.
95 tristate "STMicroelectronics ST33 I2C TPM"
99 If you have a TPM security chip from STMicroelectronics working with
100 an I2C bus say Yes and it will be accessible from within Linux.
101 To compile this driver as a module, choose M here; the module will be
102 called tpm_stm_st33_i2c.
105 tristate "XEN TPM Interface"
106 depends on TCG_TPM && XEN
107 select XEN_XENBUS_FRONTEND
109 If you want to make TPM support available to a Xen user domain,
110 say Yes and it will be accessible from within Linux. See
111 the manpages for xl, xl.conf, and docs/misc/vtpm.txt in
112 the Xen source repository for more details.
113 To compile this driver as a module, choose M here; the module
114 will be called xen-tpmfront.
