2 # TPM device configuration
6 tristate "TPM Hardware Support"
10 select CRYPTO_HASH_INFO
12 If you have a TPM security chip in your system, which
13 implements the Trusted Computing Group's specification,
14 say Yes and it will be accessible from within Linux. For
15 more information see <http://www.trustedcomputinggroup.org>.
16 An implementation of the Trusted Software Stack (TSS), the
17 userspace enablement piece of the specification, can be
18 obtained at: <http://sourceforge.net/projects/trousers>. To
19 compile this driver as a module, choose M here; the module
20 will be called tpm. If unsure, say N.
22 1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI
24 2) Without ACPI enabled, the BIOS event log won't be accessible,
25 which is required to validate the PCR 0-7 values.

35 device. This allows the kernel to collect randomness from the TPM at
36 boot, and provides the TPM randomines in /dev/hwrng.

62 If you have a TPM security chip which is connected to a regular,
63 non-tcg SPI master (i.e. most embedded platforms) that is compliant with the
64 TCG TIS 1.3 TPM specification (TPM1.2) or the TCG PTP FIFO
65 specification (TPM2.0) say Yes and it will be accessible from
66 within Linux. To compile this driver as a module, choose M here;
67 the module will be called tpm_tis_spi.
69 config TCG_TIS_I2C_ATMEL
70 tristate "TPM Interface Specification 1.2 Interface (I2C - Atmel)"
73 If you have an Atmel I2C TPM security chip say Yes and it will be
74 accessible from within Linux.
75 To compile this driver as a module, choose M here; the module will
76 be called tpm_tis_i2c_atmel.
78 config TCG_TIS_I2C_INFINEON
79 tristate "TPM Interface Specification 1.2 Interface (I2C - Infineon)"
82 If you have a TPM security chip that is compliant with the
83 TCG TIS 1.2 TPM specification and Infineon's I2C Protocol Stack
84 Specification 0.20 say Yes and it will be accessible from within
86 To compile this driver as a module, choose M here; the module
87 will be called tpm_i2c_infineon.
89 config TCG_TIS_I2C_NUVOTON
90 tristate "TPM Interface Specification 1.2 Interface (I2C - Nuvoton)"
93 If you have a TPM security chip with an I2C interface from
94 Nuvoton Technology Corp. say Yes and it will be accessible
96 To compile this driver as a module, choose M here; the module
97 will be called tpm_i2c_nuvoton.
100 tristate "National Semiconductor TPM Interface"
103 If you have a TPM security chip from National Semiconductor
104 say Yes and it will be accessible from within Linux. To
105 compile this driver as a module, choose M here; the module
106 will be called tpm_nsc.
109 tristate "Atmel TPM Interface"
110 depends on PPC64 || HAS_IOPORT_MAP
112 If you have a TPM security chip from Atmel say Yes and it
113 will be accessible from within Linux. To compile this driver
114 as a module, choose M here; the module will be called tpm_atmel.
117 tristate "Infineon Technologies TPM Interface"
120 If you have a TPM security chip from Infineon Technologies
121 (either SLD 9630 TT 1.1 or SLB 9635 TT 1.2) say Yes and it
122 will be accessible from within Linux.
123 To compile this driver as a module, choose M here; the module
124 will be called tpm_infineon.
125 Further information on this driver and the supported hardware
126 can be found at http://www.trust.rub.de/projects/linux-device-driver-infineon-tpm/
129 tristate "IBM VTPM Interface"
130 depends on PPC_PSERIES
132 If you have IBM virtual TPM (VTPM) support say Yes and it
133 will be accessible from within Linux. To compile this driver
134 as a module, choose M here; the module will be called tpm_ibmvtpm.
137 tristate "XEN TPM Interface"
138 depends on TCG_TPM && XEN
139 select XEN_XENBUS_FRONTEND
141 If you want to make TPM support available to a Xen user domain,
142 say Yes and it will be accessible from within Linux. See
143 the manpages for xl, xl.conf, and docs/misc/vtpm.txt in
144 the Xen source repository for more details.
145 To compile this driver as a module, choose M here; the module
146 will be called xen-tpmfront.
149 tristate "TPM 2.0 CRB Interface"
152 If you have a TPM security chip that is compliant with the
153 TCG CRB 2.0 TPM specification say Yes and it will be accessible
154 from within Linux. To compile this driver as a module, choose
155 M here; the module will be called tpm_crb.
157 config TCG_VTPM_PROXY
158 tristate "VTPM Proxy Interface"
161 This driver proxies for an emulated TPM (vTPM) running in userspace.
162 A device /dev/vtpmx is provided that creates a device pair
163 /dev/vtpmX and a server-side file descriptor on which the vTPM
164 can receive commands.
