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.

The tpm driver was written by Michael Shalayeff and Hans-Joerg Hoexer.
