- 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.

- Procfs interface for ACPI is made optional for back-compatible.

- /proc/acpi/info is deprecated by

+ 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).

+ help
+ This driver adds support for the ACPI-WMI (Windows Management
+ Instrumentation) mapper device (PNP0C14) found on some systems.
+
+ ACPI-WMI is a proprietary extension to ACPI to expose parts of the
+ ACPI firmware to userspace - this is done through various vendor
+ defined methods and data blocks in a PNP0C14 device, which are then
+ made available for userspace to call.
+
+ The implementation of this in Linux currently only exposes this to
+ other kernel space drivers.
+
+ This driver is a required dependency to build the firmware specific
+ drivers needed on many machines, including Acer and HP laptops.
+
+ It is safe to enable this driver even if your DSDT doesn't define
+ any ACPI-WMI devices.
