menuconfig TCG_TPM
tristate "TPM Hardware Support"
depends on HAS_IOMEM
depends on EXPERIMENTAL
select SECURITYFS
---help---
If you have a TPM security chip in your system, which
implements the Trusted Computing Group's specification,
say Yes and it will be accessible from within Linux. For
more information see <http://www.trustedcomputinggroup.org>.
An implementation of the Trusted Software Stack (TSS), the
userspace enablement piece of the specification, can be
obtained at: <http://sourceforge.net/projects/trousers>. To
compile this driver as a module, choose M here; the module
will be called tpm. If unsure, say N.
Notes:
1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI
and CONFIG_PNPACPI.
2) Without ACPI enabled, the BIOS event log won't be accessible,
which is required to validate the PCR 0-7 values.
if TCG_TPM
config TCG_TIS
tristate "TPM Interface Specification 1.2 Interface"
---help---
If you have a TPM security chip that is compliant with the
TCG TIS 1.2 TPM specification say Yes and it will be accessible
from within Linux. To compile this driver as a module, choose
M here; the module will be called tpm_tis.
config TCG_NSC
tristate "National Semiconductor TPM Interface"
---help---
If you have a TPM security chip from National Semiconductor
say Yes and it will be accessible from within Linux. To
compile this driver as a module, choose M here; the module
will be called tpm_nsc.
config TCG_ATMEL
tristate "Atmel TPM Interface"
depends on PPC64 || HAS_IOPORT
---help---
If you have a TPM security chip from Atmel say Yes and it
will be accessible from within Linux. To compile this driver
as a module, choose M here; the module will be called tpm_atmel.
config TCG_INFINEON
tristate "Infineon Technologies TPM Interface"
depends on PNP
---help---
If you have a TPM security chip from Infineon Technologies
(either SLD 9630 TT 1.1 or SLB 9635 TT 1.2) say Yes and it
will be accessible from within Linux.
To compile this driver as a module, choose M here; the module
will be called tpm_infineon.
Further information on this driver and the supported hardware
can be found at http://www.trust.rub.de/projects/linux-device-driver-infineon-tpm/
