- 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.

- The Procfs interface for ACPI is made optional for backward compatibility.
- As the same functions are duplicated in the 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+ they have been replaced by functions in /sys.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)
