|
|
|
|
|
.Sh SYNOPSIS
|
|
|
|
|
To compile this driver into the kernel,
|
|
|
|
|
place the following line in your
|
|
|
|
|
kernel configuration file:
|
|
|
|
|
.Bd -ragged -offset indent
|
|
|
|
|
.Cd "device acpi_aiboost"
|
|
|
|
|
.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
|
|
|
|
|
acpi_aiboost_load="YES"
|
|
|
|
|
.Ed
|
|
|
|
|
.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver provides support for monitoring the hardware sensors in recent
|
|
|
|
|
.Tn ASUS
|
|
|
|
|
motherboards.
|
|
|
|
|
The driver uses ACPI as the backend to fetch sensor values and
|
|
|
|
|
descriptions and provides its data via the
|
|
|
|
|
.Xr sysctl 8
|
2007-03-30 21:59:55 +00:00
|
|
|
interface, under dev.acpi_aiboost.0 namespace.
|
2008-12-13 09:33:03 +00:00
|
|
|
Descriptions for these values are available
|
|
|
|
|
with sysctl -d.

|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver typically has 7 sensors, depending on the motherboard and
|
|
|
|
|
chipset:

.Sh HISTORY
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver first appeared in
|
|
|
|
|
.Fx 7.0 .

The
|
|
|
|
|
.Nm
|
|
|
|
|
driver was written by
|
|
|
|
|
.An Takanori Watanabe .
|
|
|
|
|
This manual page was written by
|
|
|
|
|
.An Juan Romero Pardines ,
|
|
|
|
|
who adapted the code for
|
|
|
|
|
.Nx ,
|
|
|
|
|
and adopted back to FreeBSD by
|
|
|
|
|
.An Takanori Watanabe .
|
|
|
|
|
.Sh BUGS
|
|
|
|
|
It's possible to modify voltages via the ACPI methods in the DSDT,
|
|
|
|
|
but for now the driver only reports the sensors' values.
|
|
|
|
|
CPU Q-Fan is another thing that is typically specified in the ACPI
|
|
|
|
|
namespace, and in the future we should handle this feature (to
|
|
|
|
|
enable or disable automatic/manual fan mode).
