TPM(4) Device Drivers Manual TPM(4)

tpm — Trusted Platform Module

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"

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.
