+.Sh NAME
+.Nm smu
+.Nd Apple System Management Unit Driver
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following lines in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device smu"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the System Management Unit (SMU) found in many
+Apple G5 systems.
+This includes most Power Macintosh G5 and all iMac G5 systems.
+.Pp
+The Apple SMU controller provides software power management and thermal
+control functionality, and is responsible for managing system cooling
+devices.
+.Sh HARDWARE
+Chips supported by the
+.Nm
+driver include:
+.Pp
+.Bl -bullet -compact
+.It
+Apple System Management Unit
+.El
+.Sh THERMAL MANAGEMENT
+The
+.Nm
+driver provides basic automatic thermal management. Without a userspace
+daemon providing more advanced control, the driver will attempt to maintain
+system temperatures in a conservative range through coarse-grained control of
+system cooling devices (see below). Automatic kernel-level thermal control
+will take over if more than 3 seconds elapses between userspace cooling
+setting adjustments.
+.Sh SYSCTL VARIABLES
+The
+.Nm
+driver provides power management services and thermal readout through a
+sysctl interface.
+The following sysctls can be used to control the
+power management behavior and to examine current system power and
+thermal conditions.
+.Bl -tag -width indent
+.It Va dev.smu.%d.server_mode
+Restart after power failure behavior (1 causes system to reboot after power
+cut, 0 causes system to remain off).
+.It Va dev.smu.%d.target_temp
+Target system temperature, in degrees Celsius. The
+.Nm
+driver will attempt to adjust fans to maintain the temperature of the
+warmest component in the system at or below this level.
+.It Va dev.smu.%d.critical_temp
+System critical temperature, in degrees Celsius. If any component in
+the system exceeds this temperature, the machine will be shut down within
+500 ms.
+.It Va dev.smu.%d.fans.%s.minrpm
+Minimum allowed speed for this fan.
+.It Va dev.smu.%d.fans.%s.maxrpm
+Maximum allowed speed for this fan.
+.It Va dev.smu.%d.fans.%s.rpm
+Current speed for this fan. The fan speed can be adjusted by changing this
+sysctl. If more than 3 seconds elapses between fan speed adjustments, the
+kernel will resume automatic control of the fan.
+.It Va dev.smu.%d.sensors.%s
+Current reading from this sensor. Four sensor types are supported. Temperature
+sensors are in units of degrees Celsius, current sensors in milliamps, voltage
+sensors in millivolts, and power sensors in milliwatts.
+.El
+.Sh LED INTERFACE
+The
+.Nm
+driver provides an
+.Xr led 4
+annunciator interface at
+.Pa /dev/led/sleepled .

+.Cd "device tsec"
+.Cd "device miibus"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the gigabit Ethernet controller integrated in
+some of the Freescale system-on-chip devices.
+.Pp
+The
+.Nm
+driver supports the following media types:
+.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
+.It autoselect
+Enable autoselection of the media type and options
+.It 10baseT/UTP
+Set 10Mbps operation

+.El
+.Pp
+The
+.Nm
+driver supports the following media options:
+.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
+.It full-duplex
+Set full duplex operation
+.El
+.Pp
+The
+.Nm
+driver supports polled operation when the system is configured with
+DEVICE_POLLING kernel option, see
+.Xr polling 4
+for more details.
+.Pp
+The
+.Nm
+driver supports reception and transmission of extended frames
+for
+.Xr vlan 4 .
+This capability of
+.Nm
+can be controlled by means of the
+.Cm vlanmtu
+parameter
+to
+.Xr ifconfig 8 .
+.Pp
+The
+.Nm
+driver supports interrupts coalescing (IC) so that raising a transmit/receive
+frame interrupt is delayed, if possible, until a threshold-defined period of
+time has elapsed, or a threshold-defined frame counter has been reached
+(whichever occurs first). The following sysctls regulate this behaviour:
+.Bl -tag -width indent
+.It Va dev.tsec.X.int_coal.rx_time
+.It Va dev.tsec.X.int_coal.rx_count
+.It Va dev.tsec.X.int_coal.tx_time
+.It Va dev.tsec.X.int_coal.tx_count
+.Pp
+Value of 0 for either time or count disables IC on the given path. Time value
+1-65535 corresponds to a real time period and is expressed in units equivalent
+to 64 ticks of the TSEC clock. Count 1-255 represents the number of frames
+(note that value of 1 is equivalent to IC disabled). User provided values
+larger than supported will be trimmed to the maximum supported. More details
+are available in the reference manual of the device.
+.El
+.Sh HARDWARE
+Gigabit Ethernet controllers built into the following Freescale
+system-on-chip devices are known to work with the
+.Nm
+driver:
+.Pp
+.Bl -bullet -compact
