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_ATMEL
37 tristate "TPM Interface Specification 1.2 Interface (I2C - Atmel)"
40 If you have an Atmel I2C TPM security chip say Yes and it will be
41 accessible from within Linux.
42 To compile this driver as a module, choose M here; the module will
43 be called tpm_tis_i2c_atmel.
45 config TCG_TIS_I2C_INFINEON
46 tristate "TPM Interface Specification 1.2 Interface (I2C - Infineon)"
49 If you have a TPM security chip that is compliant with the
50 TCG TIS 1.2 TPM specification and Infineon's I2C Protocol Stack
51 Specification 0.20 say Yes and it will be accessible from within
53 To compile this driver as a module, choose M here; the module
54 will be called tpm_i2c_infineon.
56 config TCG_TIS_I2C_NUVOTON
57 tristate "TPM Interface Specification 1.2 Interface (I2C - Nuvoton)"
60 If you have a TPM security chip with an I2C interface from
61 Nuvoton Technology Corp. say Yes and it will be accessible
63 To compile this driver as a module, choose M here; the module
64 will be called tpm_i2c_nuvoton.
67 tristate "National Semiconductor TPM Interface"
70 If you have a TPM security chip from National Semiconductor
71 say Yes and it will be accessible from within Linux. To
72 compile this driver as a module, choose M here; the module
73 will be called tpm_nsc.
76 tristate "Atmel TPM Interface"
77 depends on PPC64 || HAS_IOPORT_MAP
79 If you have a TPM security chip from Atmel say Yes and it
80 will be accessible from within Linux. To compile this driver
81 as a module, choose M here; the module will be called tpm_atmel.
84 tristate "Infineon Technologies TPM Interface"
87 If you have a TPM security chip from Infineon Technologies
88 (either SLD 9630 TT 1.1 or SLB 9635 TT 1.2) say Yes and it
89 will be accessible from within Linux.
90 To compile this driver as a module, choose M here; the module
91 will be called tpm_infineon.
92 Further information on this driver and the supported hardware
93 can be found at http://www.trust.rub.de/projects/linux-device-driver-infineon-tpm/
96 tristate "IBM VTPM Interface"
97 depends on PPC_PSERIES
99 If you have IBM virtual TPM (VTPM) support say Yes and it
100 will be accessible from within Linux. To compile this driver
101 as a module, choose M here; the module will be called tpm_ibmvtpm.
104 tristate "XEN TPM Interface"
105 depends on TCG_TPM && XEN
106 select XEN_XENBUS_FRONTEND
108 If you want to make TPM support available to a Xen user domain,
109 say Yes and it will be accessible from within Linux. See
110 the manpages for xl, xl.conf, and docs/misc/vtpm.txt in
111 the Xen source repository for more details.
112 To compile this driver as a module, choose M here; the module
113 will be called xen-tpmfront.
116 tristate "TPM 2.0 CRB Interface"
117 depends on X86 && ACPI
119 If you have a TPM security chip that is compliant with the
120 TCG CRB 2.0 TPM specification say Yes and it will be accessible
121 from within Linux. To compile this driver as a module, choose
122 M here; the module will be called tpm_crb.
