TPM(4)		       FreeBSD Kernel Interfaces Manual			TPM(4)

NAME
     tpm -- Trusted Platform Module

SYNOPSIS
     To	compile	this driver into the kernel, place the following lines in your
     kernel configuration file:

	   device tpm

     Alternatively, to load the	driver as a module at boot time, place the
     following line in loader.conf(5):

	   tpm_load="YES"

     In	/boot/device.hints:
     hint.tpm.0.at="isa"
     hint.tpm.0.maddr="0xfed40000"
     hint.tpm.0.msize="0x5000"
     hint.tpm.1.at="isa"
     hint.tpm.1.maddr="0xfed40000"
     hint.tpm.1.msize="0x1000"

DESCRIPTION
     The tpm driver provides support for various trusted platform modules
     (TPM) that	can store cryptographic	keys.

     Supported modules:

	   +o   Atmel 97SC3203
	   +o   Broadcom	BCM0102
	   +o   Infineon	IFX SLD	9630 TT	1.1 and	IFX SLB	9635 TT	1.2
	   +o   Intel INTC0102
	   +o   Sinosun SNS SSX35
	   +o   STM ST19WP18
	   +o   Winbond WEC WPCT200

     The driver	can be configured to use an IRQ	by providing a free ISA	inter-
     rupt vector in /boot/device.hints.
