TPM(4)                  NetBSD 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:

           ·   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.
