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.
