TPM(4)                       Device Drivers 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:

              TPM 2.0 chips over ACPI
              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.
