- 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 )
+ A user-space daemon, acpi, typically read /proc/acpi/event
+ and handled all ACPI sub-system generated events.
+
+ These events are now delivered to user-space via
+ either the input layer, or as netlink events.
+
+ This build option enables the old code for legacy
+ user-space implementation. After some time, this will
+ be moved under CONFIG_ACPI_PROCFS, and then deleted.
+
+ Say Y here to retain the old behaviour. Say N if your
+ user-space is newer than kernel 2.6.23 (September 2007).
