TPM(4) FreeBSD Kernel Interfaces Manual TPM(4)
NAME
tpm - Trusted Platform Module
SYNOPSIS
tpm* at isa? iomem 0xfed40000
tpm* at acpi?
DESCRIPTION
The tpm driver provides support for various Trusted Platform Module (TPM)
chips.
Supported modules:
o TPM 2.0 chips over ACPI
o TPM 1.2 chips over ACPI and ISA
Note that the supported interface version is TIS1.2 in each case.
The TPM may need to be enabled in the system's firmware or BIOS, which
requires a reboot to take effect. This is generally beyond the control
of NetBSD. Enabling a TPM does not require using trusted boot -- it can
be enabled, for example, only for the rnd(4) entropy source.
