| ---help--- | |
| Advanced Configuration and Power Interface (ACPI) support for | |
| Linux requires an ACPI compliant platform (hardware/firmware), | |
| and assumes the presence of OS-directed configuration and power | |
| management (OSPM) software. This option will enlarge your | |
| kernel by about 70K. | |
| Linux ACPI provides a robust functional replacement for several | |
| legacy configuration and power management interfaces, including | |
| the Plug-and-Play BIOS specification (PnP BIOS), the | |
| MultiProcessor Specification (MPS), and the Advanced Power | |
| Management (APM) specification. If both ACPI and APM support | |
| are configured, whichever is loaded first shall be used. | |
| The ACPI SourceForge project contains the latest source code, | |
| documentation, tools, mailing list subscription, and other | |
| information. This project is available at: | |
| <http://sourceforge.net/projects/acpi> | |
| Linux support for ACPI is based on Intel Corporation's ACPI | |
| Component Architecture (ACPI CA). For more information see: | |
| <http://developer.intel.com/technology/iapc/acpi> | |
| ACPI is an open industry specification co-developed by Compaq, | |
| Intel, Microsoft, Phoenix, and Toshiba. The specification is | |
| available at: | |

| 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. | |

| ACPI 2.0 Specification, Appendix B, allowing to perform some basic | |
| control like defining the video POST device, retrieving EDID information | |
| or to setup a video output, etc. | |

| This driver installs ACPI as the idle handler for Linux, and uses | |

| This driver adds support for ACPI thermal zones. Most mobile and | |
| some desktop systems support ACPI thermal zones. It is HIGHLY | |

| tristate "ASUS/Medion Laptop Extras" | |
| depends on X86 | |
| default y | |
| ---help--- | |
| This driver provides support for extra features of ACPI-compatible | |
| ASUS laptops. As some of Medion laptops are made by ASUS, it may also | |
| support some Medion laptops (such as 9675 for example). It makes all | |
| the extra buttons generate standard ACPI events that go through | |
| /proc/acpi/events, and (on some models) adds support for changing the | |
| display brightness and output, switching the LCD backlight on and off, | |
| and most importantly, allows you to blink those fancy LEDs intended | |
| for reporting mail and wireless status. | |
| Note: display switching code is currently considered EXPERIMENTAL, | |
| toying with these values may even lock your machine. | |
| All settings are changed via /proc/acpi/asus directory entries. Owner | |
| and group for these entries can be set with asus_uid and asus_gid | |
| parameters. | |
| More information and a userspace daemon for handling the extra buttons | |
| at <http://sourceforge.net/projects/acpi4asus/>. | |
| If you have an ACPI-compatible ASUS laptop, say Y or M here. This | |
| driver is still under development, so if your laptop is unsupported or | |
| something works not quite as expected, please use the mailing list | |
| available on the above page (acpi4asus-user@lists.sourceforge.net) | |

| config ACPI_TOSHIBA | |
| tristate "Toshiba Laptop Extras" | |
| depends on X86 | |
| default y | |
| ---help--- | |
| This driver adds support for access to certain system settings | |
| on "legacy free" Toshiba laptops. These laptops can be recognized by | |
| their lack of a BIOS setup menu and APM support. | |
| On these machines, all system configuration is handled through the | |
| ACPI. This driver is required for access to controls not covered | |
| by the general ACPI drivers, such as LCD brightness, video output, | |
| etc. | |
| This driver differs from the non-ACPI Toshiba laptop driver (located | |
| under "Processor type and features") in several aspects. | |
| Configuration is accessed by reading and writing text files in the | |
| /proc tree instead of by program interface to /dev. Furthermore, no | |
| power management functions are exposed, as those are handled by the | |
| general ACPI drivers. | |
| More information about this driver is available at | |
| <http://memebeam.org/toys/ToshibaAcpiDriver>. | |

| series), say Y. | |

| on platforms with DMI BIOS date before January 1st that year. | |
| "acpi=force" can be used to override this mechanism. | |
| Enter 0 to disable this mechanism and allow ACPI to | |
| run by default no matter what the year. (default) | |
| config ACPI_DEBUG | |
| bool "Debug Statements" | |
| default n | |
| help | |
| The ACPI driver can optionally report errors with a great deal | |

| help | |
| The Power Management Timer is available on all ACPI-capable, | |
| in most cases even if ACPI is unusable or blacklisted. | |
| This timing source is not affected by powermanagement features | |
| like aggressive processor idling, throttling, frequency and/or | |
| voltage scaling, unlike the commonly used Time Stamp Counter | |
| (TSC) timing source. | |
| So, if you see messages like 'Losing too many ticks!' in the | |
| kernel logs, and/or you are using this on a notebook which | |
| does not yet have an HPET, you should say "Y" here. | |

| ---help--- | |
| This allows _physical_ insertion and removal of CPUs and memory. | |
| This can be useful, for example, on NUMA machines that support | |
| ACPI based physical hotplug of nodes, or non-NUMA machines that | |

| This driver adds supports for ACPI Memory Hotplug. This driver | |
| provides support for fielding notifications on ACPI memory | |
| devices (PNP0C80) which represent memory ranges that may be | |
| onlined or offlined during runtime. | |
| Enabling this driver assumes that your platform hardware | |
| and firmware have support for hot-plugging physical memory. If | |
| your system does not support physically adding or ripping out | |
| memory DIMMs at some platfrom defined granularity (individually | |
| or as a bank) at runtime, then you need not enable this driver. | |
| If one selects "m," this driver can be loaded using the following | |
| command: | |
| $>modprobe acpi_memhotplug | |
