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:

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

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