+.Sh NAME
+.Nm longrun
+.Nd Transmeta(TM) Crusoe(TM) LongRun(TM) support
+.Sh SYNOPSIS
+LongRun support is a collection of power saving modes for the
+Transmeta Crusoe chips, similar in scope to Intel's SpeedStep.
+The following
+.Xr sysctl 8
+MIBs control the different CPU modes:
+.Bl -tag -width "hw.crusoe.percentage integer no         " -compact
+.It Sy "Name                 Type    Changeable Description
+.It "hw.crusoe.longrun    integer yes        LongRun mode.
+.Bl -tag -width "0: minimum frequency mode" -compact
+.It "0: minimum frequency mode
+.It "1: power-saving mode
+.It "2: performance mode
+.It "3: maximum frequency mode
+.El
+.It "hw.crusoe.frequency  integer no         Current frequency (MHz).
+.It "hw.crusoe.voltage    integer no         Current voltage (mV).
+.It "hw.crusoe.percentage integer no         Processing performance (%).
+.El
+.Pp
+.Sh EXAMPLES
+Print the current status:
+.Bd -literal -offset indent
+% sysctl hw.crusoe
+.Ed
+.Pp
+To set LongRun mode to performance oriented variable frequency mode
+(less power savings):
+.Bd -literal -offset indent
+# sysctl -w hw.crusoe.longrun=2
