29.Os
30.Sh NAME
31.Nm acpi_rapidstart
32.Nd "Intel rapid start technology ACPI driver"
33.Sh SYNOPSIS
34To compile this driver into the kernel,
35place the following line in your
36kernel configuration file:
37.Bd -ragged -offset indent
38.Cd "device acpi_rapidstart"
39.Ed
40.Pp
41Alternatively, to load the driver as a
42module at boot time, place the following line in
43.Xr loader.conf 5 :
44.Bd -literal -offset indent
45acpi_rapidstart_load="YES"
46.Ed
47.Sh DESCRIPTION
48The
49.Nm
50driver provides support for Intel Rapid Start technology ACPI device interface.
51Note that this is only for ACPI device interface . This has _CID PNP0C02 so
52should be loaded in boot time to avoid attaching acpi_sysresource driver.

54.Sh SYSCTLS
55The following sysctl nodes are currently implemented:
56.Bl -tag -width indent
57.It Va dev.acpi_rapidstart.0.ffs
