tpm(4) 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.conf5:


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


The 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
