NAME

     acpi_rapidstart — Intel rapid start technology ACPI driver

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel
     configuration file:

           device acpi_rapidstart

     Alternatively, to load the driver as a module at boot time, place the following line in
     loader.conf(5):

           acpi_rapidstart_load="YES"

DESCRIPTION

     The acpi_rapidstart driver provides support for Intel Rapid Start technology ACPI device
     interface.  Note that this is only for the ACPI device interface.  This has _CID PNP0C02 so
     it should be loaded at boot time to avoid attaching to the acpi_sysresource driver.

SYSCTLS

     The following sysctl(8) nodes are currently implemented:

     dev.acpi_rapidstart.0.ffs
             Rapid start flag.  It is a bitwise OR of the following:

             1           Enter Fast Flash Standby in RTC wake.
             2           Enter Fast Flash Standby in Critical Battery Wake enable

     dev.acpi_rapidstart.0.ftv
             Fast Flash Standby timer value in minutes.
