63 be called tpm_tis_i2c_atmel.
65 config TCG_TIS_I2C_INFINEON
66 tristate "TPM Interface Specification 1.2 Interface (I2C - Infineon)"
69 If you have a TPM security chip that is compliant with the
70 TCG TIS 1.2 TPM specification and Infineon's I2C Protocol Stack
71 Specification 0.20 say Yes and it will be accessible from within
73 To compile this driver as a module, choose M here; the module
74 will be called tpm_i2c_infineon.
76 config TCG_TIS_I2C_NUVOTON
77 tristate "TPM Interface Specification 1.2 Interface (I2C - Nuvoton)"
80 If you have a TPM security chip with an I2C interface from
81 Nuvoton Technology Corp. say Yes and it will be accessible
83 To compile this driver as a module, choose M here; the module
84 will be called tpm_i2c_nuvoton.
87 tristate "National Semiconductor TPM Interface"
90 If you have a TPM security chip from National Semiconductor
91 say Yes and it will be accessible from within Linux. To
92 compile this driver as a module, choose M here; the module
93 will be called tpm_nsc.
96 tristate "Atmel TPM Interface"
97 depends on PPC64 || HAS_IOPORT_MAP
99 If you have a TPM security chip from Atmel 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_atmel.
104 tristate "Infineon Technologies TPM Interface"
107 If you have a TPM security chip from Infineon Technologies
108 (either SLD 9630 TT 1.1 or SLB 9635 TT 1.2) say Yes and it
109 will be accessible from within Linux.
110 To compile this driver as a module, choose M here; the module
111 will be called tpm_infineon.
112 Further information on this driver and the supported hardware
113 can be found at http://www.trust.rub.de/projects/linux-device-driver-infineon-tpm/
116 tristate "IBM VTPM Interface"
117 depends on PPC_PSERIES
119 If you have IBM virtual TPM (VTPM) support say Yes and it
120 will be accessible from within Linux. To compile this driver
121 as a module, choose M here; the module will be called tpm_ibmvtpm.
124 tristate "XEN TPM Interface"
125 depends on TCG_TPM && XEN
126 select XEN_XENBUS_FRONTEND
128 If you want to make TPM support available to a Xen user domain,
129 say Yes and it will be accessible from within Linux. See
130 the manpages for xl, xl.conf, and docs/misc/vtpm.txt in
131 the Xen source repository for more details.
132 To compile this driver as a module, choose M here; the module
133 will be called xen-tpmfront.
136 tristate "TPM 2.0 CRB Interface"

144 config TCG_VTPM_PROXY
145 tristate "VTPM Proxy Interface"
149 This driver proxies for an emulated TPM (vTPM) running in userspace.
150 A device /dev/vtpmx is provided that creates a device pair
151 /dev/vtpmX and a server-side file descriptor on which the vTPM
152 can receive commands.
