30 .Nd "Intel rapid start technology ACPI driver"
32 To compile this driver into the kernel,
33 place the following line in your
34 kernel configuration file:
35 .Bd -ragged -offset indent
36 .Cd "device acpi_rapidstart"
39 Alternatively, to load the driver as a
40 module at boot time, place the following line in
42 .Bd -literal -offset indent
43 acpi_rapidstart_load="YES"
48 driver provides support for Intel Rapid Start technology ACPI device interface.
49 Note that this is only for the ACPI device interface.
50 This has _CID PNP0C02 so it should be loaded at boot time to avoid attaching
51 to the acpi_sysresource driver.
55 nodes are currently implemented:
56 .Bl -tag -width indent
57 .It Va dev.acpi_rapidstart.0.ffs
59 It is a bitwise OR of the following:
61 .Bl -tag -width indent-two -compact
63 Enter Fast Flash Standby in RTC wake.
65 Enter Fast Flash Standby in Critical Battery Wake enable
67 .It Va dev.acpi_rapidstart.0.ftv
68 Fast Flash Standby timer value in minutes.
76 driver first appeared in
82 .An Takanori Watanabe Aq Mt takawata@FreeBSD.org .
