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 186 support some Medion laptops (such as 9675 for example). It makes all 187 the extra buttons generate standard ACPI events that go through 188 /proc/acpi/events, and (on some models) adds support for changing the 189 display brightness and output, switching the LCD backlight on and off, 190 and most importantly, allows you to blink those fancy LEDs intended 191 for reporting mail and wireless status. 192 193 Note: display switching code is currently considered EXPERIMENTAL, 194 toying with these values may even lock your machine. 195 196 All settings are changed via /proc/acpi/asus directory entries. Owner 197 and group for these entries can be set with asus_uid and asus_gid 198 parameters. 199 200 More information and a userspace daemon for handling the extra buttons 201 at <http://sourceforge.net/projects/acpi4asus/>. 202 203 If you have an ACPI-compatible ASUS laptop, say Y or M here.

These laptops can be recognized by 228 their lack of a BIOS setup menu and APM support. 229 230 On these machines, all system configuration is handled through the 231 ACPI. This driver is required for access to controls not covered 232 by the general ACPI drivers, such as LCD brightness, video output, 233 etc. 234 235 This driver differs from the non-ACPI Toshiba laptop driver (located 236 under "Processor type and features") in several aspects. 237 Configuration is accessed by reading and writing text files in the 238 /proc tree instead of by program interface to /dev. Furthermore, no 239 power management functions are exposed, as those are handled by the 240 general ACPI drivers. 241 242 More information about this driver is available at 243 <http://memebeam.org/toys/ToshibaAcpiDriver>. 244 245 If you have a legacy free Toshiba laptop (such as the Libretto L1 246 series), say Y. 247 248config ACPI_CUSTOM_DSDT 249 bool "Include Custom DSDT" 250 depends on !STANDALONE 251 default n 252 help 253 Thist option is to load a custom ACPI DSDT 254 If you don't know what that is, say N. 255 256config ACPI_CUSTOM_DSDT_FILE 257 string "Custom DSDT Table file to include" 258 depends on ACPI_CUSTOM_DSDT 259 default "" 260 help 261 Enter the full path name to the file wich includes the AmlCode declaration. 262 263config ACPI_BLACKLIST_YEAR 264 int "Disable ACPI for systems before Jan 1st this year" 265 depends on ACPI_INTERPRETER 266 default 0 267 help 268 enter a 4-digit year, eg. 2001 to disable ACPI by default 269 on platforms with DMI BIOS date before January 1st that year. 270 "acpi=force" can be used to override this mechanism. 271 272 Enter 0 to disable this mechanism and allow ACPI to 273 run by default no matter what the year.

If 358 your system does not support physically adding or ripping out 359 memory DIMMs at some platfrom defined granularity (individually 360 or as a bank) at runtime, then you need not enable this driver. 361 362 If one selects "m," this driver can be loaded using the following 363 command: 364 $>modprobe acpi_memhotplug 365endif # ACPI 366 367endmenu 368
