config ACPI_SLEEP

- depends on X86 && (!SMP || SUSPEND_SMP)
- depends on PM
- default y
- ---help---
- This option adds support for ACPI suspend states.
-
- With this option, you will be able to put the system "to sleep".
- Sleep states are low power states for the system and devices. All
- of the system operating state is saved to either memory or disk
- (depending on the state), to allow the system to resume operation
- quickly at your request.
-
- Although this option sounds really nifty, barely any of the device
- drivers have been converted to the new driver model and hence few
- have proper power management support.
-
- This option is not recommended for anyone except those doing driver
- power management development.

---help---
- Procfs interface for ACPI is made optional for back-compatible.
- As the same functions are duplicated in sysfs interface
- and this proc interface will be removed some time later,
- it's marked as deprecated.
- ( /proc/acpi/debug_layer && debug_level are deprecated by
- /sys/module/acpi/parameters/debug_layer && debug_level.
- /proc/acpi/info is deprecated by
- /sys/module/acpi/parameters/acpica_version )
+ For backwards compatibility, this option allows
+ depricated /proc/acpi/ files to exist, even when
+ they have been replaced by functions in /sys.
+ The deprecated files (and their replacements) include:
+
+ /proc/acpi/sleep (/sys/power/state)
+ /proc/acpi/info (/sys/modules/acpi/parameters/acpica_version)
+ /proc/acpi/dsdt (/sys/firmware/acpi/tables/DSDT)
+ /proc/acpi/fadt (/sys/firmware/acpi/tables/FACP)
+ /proc/acpi/debug_layer (/sys/module/acpi/parameters/debug_layer)
+ /proc/acpi/debug_level (/sys/module/acpi/parameters/debug_level)
+
+ This option has no effect on /proc/acpi/ files
+ and functions which do not yet exist in /sys.

+ Say N to delete /proc/acpi/ files that have moved to /sys/

This driver adds support for ACPI controlled removable drive

NOTE: This driver is deprecated and will probably be removed soon,
use asus-laptop instead.

- output switching, ThinkLight control, UltraBay eject and more.
- For more information about this driver see <file:Documentation/ibm-acpi.txt>
