65 be called tpm_tis_i2c_atmel.
67 config TCG_TIS_I2C_INFINEON
68 tristate "TPM Interface Specification 1.2 Interface (I2C - Infineon)"
71 If you have a TPM security chip that is compliant with the
72 TCG TIS 1.2 TPM specification and Infineon's I2C Protocol Stack
73 Specification 0.20 say Yes and it will be accessible from within
75 To compile this driver as a module, choose M here; the module
76 will be called tpm_i2c_infineon.
78 config TCG_TIS_I2C_NUVOTON
79 tristate "TPM Interface Specification 1.2 Interface (I2C - Nuvoton)"
82 If you have a TPM security chip with an I2C interface from
83 Nuvoton Technology Corp. say Yes and it will be accessible
85 To compile this driver as a module, choose M here; the module
86 will be called tpm_i2c_nuvoton.
89 tristate "National Semiconductor TPM Interface"
92 If you have a TPM security chip from National Semiconductor
93 say Yes and it will be accessible from within Linux. To
94 compile this driver as a module, choose M here; the module
95 will be called tpm_nsc.
98 tristate "Atmel TPM Interface"
99 depends on PPC64 || HAS_IOPORT_MAP
101 If you have a TPM security chip from Atmel say Yes and it
102 will be accessible from within Linux. To compile this driver
103 as a module, choose M here; the module will be called tpm_atmel.
106 tristate "Infineon Technologies TPM Interface"
109 If you have a TPM security chip from Infineon Technologies
110 (either SLD 9630 TT 1.1 or SLB 9635 TT 1.2) say Yes and it
111 will be accessible from within Linux.
112 To compile this driver as a module, choose M here; the module
113 will be called tpm_infineon.
114 Further information on this driver and the supported hardware
115 can be found at http://www.trust.rub.de/projects/linux-device-driver-infineon-tpm/
118 tristate "IBM VTPM Interface"

128 select XEN_XENBUS_FRONTEND
130 If you want to make TPM support available to a Xen user domain,
131 say Yes and it will be accessible from within Linux. See
132 the manpages for xl, xl.conf, and docs/misc/vtpm.txt in
133 the Xen source repository for more details.

152 A device /dev/vtpmx is provided that creates a device pair
153 /dev/vtpmX and a server-side file descriptor on which the vTPM
154 can receive commands.
