This option will enlarge your 21 kernel by about 70K. 22 23 Linux ACPI provides a robust functional replacement for several 24 legacy configuration and power management interfaces, including 25 the Plug-and-Play BIOS specification (PnP BIOS), the 26 MultiProcessor Specification (MPS), and the Advanced Power 27 Management (APM) specification. If both ACPI and APM support 28 are configured, whichever is loaded first shall be used. 29 30 The ACPI SourceForge project contains the latest source code, 31 documentation, tools, mailing list subscription, and other 32 information. This project is available at: 33 <http://sourceforge.net/projects/acpi> 34 35 Linux support for ACPI is based on Intel Corporation's ACPI 36 Component Architecture (ACPI CA). For more information see: 37 <http://developer.intel.com/technology/iapc/acpi> 38 39 ACPI is an open industry specification co-developed by Compaq, 40 Intel, Microsoft, Phoenix, and Toshiba.

All 66 of the system operating state is saved to either memory or disk 67 (depending on the state), to allow the system to resume operation 68 quickly at your request. 69 70 Although this option sounds really nifty, barely any of the device 71 drivers have been converted to the new driver model and hence few 72 have proper power management support. 73 74 This option is not recommended for anyone except those doing driver 75 power management development. 76 77config ACPI_SLEEP_PROC_FS 78 bool 79 depends on ACPI_SLEEP && PROC_FS 80 default y 81 82config ACPI_SLEEP_PROC_SLEEP 83 bool "/proc/acpi/sleep (deprecated)" 84 depends on ACPI_SLEEP_PROC_FS 85 default n 86 ---help--- 87 Create /proc/acpi/sleep 88 Deprecated by /sys/power/state 89 90config ACPI_AC 91 tristate "AC Adapter" 92 depends on X86 93 default m 94 help 95 This driver adds support for the AC Adapter object, which indicates 96 whether a system is on AC, or not.

In the future, a daemon will read 114 /proc/acpi/event and perform user-defined actions such as shutting 115 down the system. Until then, you can cat it, and see output when 116 a button is pressed. 117 118config ACPI_VIDEO 119 tristate "Video" 120 depends on EXPERIMENTAL 121 default m 122 help 123 This driver implement the ACPI Extensions For Display Adapters 124 for integrated graphics devices on motherboard, as specified in 125 ACPI 2.0 Specification, Appendix B, allowing to perform some basic 126 control like defining the video POST device, retrieving EDID information 127 or to setup a video output, etc. 128 Note that this is an ref. implementation only.

As some of Medion laptops are made by ASUS, it may also 187 support some Medion laptops (such as 9675 for example). It makes all 188 the extra buttons generate standard ACPI events that go through 189 /proc/acpi/events, and (on some models) adds support for changing the 190 display brightness and output, switching the LCD backlight on and off, 191 and most importantly, allows you to blink those fancy LEDs intended 192 for reporting mail and wireless status. 193 194 Note: display switching code is currently considered EXPERIMENTAL, 195 toying with these values may even lock your machine. 196 197 All settings are changed via /proc/acpi/asus directory entries. Owner 198 and group for these entries can be set with asus_uid and asus_gid 199 parameters. 200 201 More information and a userspace daemon for handling the extra buttons 202 at <http://sourceforge.net/projects/acpi4asus/>. 203 204 If you have an ACPI-compatible ASUS laptop, say Y or M here. This 205 driver is still under development, so if your laptop is unsupported or 206 something works not quite as expected, please use the mailing list 207 available on the above page (acpi4asus-user@lists.sourceforge.net) 208 209config ACPI_IBM 210 tristate "IBM ThinkPad Laptop Extras" 211 depends on X86 212 default m 213 ---help--- 214 This is a Linux ACPI driver for the IBM ThinkPad laptops.

These laptops can be recognized by 229 their lack of a BIOS setup menu and APM support. 230 231 On these machines, all system configuration is handled through the 232 ACPI. This driver is required for access to controls not covered 233 by the general ACPI drivers, such as LCD brightness, video output, 234 etc. 235 236 This driver differs from the non-ACPI Toshiba laptop driver (located 237 under "Processor type and features") in several aspects. 238 Configuration is accessed by reading and writing text files in the 239 /proc tree instead of by program interface to /dev. Furthermore, no 240 power management functions are exposed, as those are handled by the 241 general ACPI drivers. 242 243 More information about this driver is available at 244 <http://memebeam.org/toys/ToshibaAcpiDriver>. 245 246 If you have a legacy free Toshiba laptop (such as the Libretto L1 247 series), say Y. 248 249config ACPI_CUSTOM_DSDT 250 bool "Include Custom DSDT" 251 depends on !STANDALONE 252 default n 253 help 254 Thist option is to load a custom ACPI DSDT 255 If you don't know what that is, say N. 256 257config ACPI_CUSTOM_DSDT_FILE 258 string "Custom DSDT Table file to include" 259 depends on ACPI_CUSTOM_DSDT 260 default "" 261 help 262 Enter the full path name to the file wich includes the AmlCode declaration. 263 264config ACPI_BLACKLIST_YEAR 265 int "Disable ACPI for systems before Jan 1st this year" 266 depends on ACPI_INTERPRETER 267 default 0 268 help 269 enter a 4-digit year, eg. 2001 to disable ACPI by default 270 on platforms with DMI BIOS date before January 1st that year. 271 "acpi=force" can be used to override this mechanism. 272 273 Enter 0 to disable this mechanism and allow ACPI to 274 run by default no matter what the year.

If 359 your system does not support physically adding or ripping out 360 memory DIMMs at some platfrom defined granularity (individually 361 or as a bank) at runtime, then you need not enable this driver. 362 363 If one selects "m," this driver can be loaded using the following 364 command: 365 $>modprobe acpi_memhotplug 366endif # ACPI 367 368endmenu 369
