.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device tpm"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
tpm_load="YES"
|
|
.Ed
|
|
.Pp
|
|
In
|
|
.Pa /boot/device.hints :
|
|
.Cd hint.tpm.0.at="isa"
|
|
.Cd hint.tpm.0.maddr="0xfed40000"
|
|
.Cd hint.tpm.0.msize="0x5000"
