This option will enlarge your 20 kernel by about 70K. 21 22 Linux ACPI provides a robust functional replacement for several 23 legacy configuration and power management interfaces, including 24 the Plug-and-Play BIOS specification (PnP BIOS), the 25 MultiProcessor Specification (MPS), and the Advanced Power 26 Management (APM) specification. If both ACPI and APM support 27 are configured, whichever is loaded first shall be used. 28 29 The ACPI SourceForge project contains the latest source code, 30 documentation, tools, mailing list subscription, and other 31 information. This project is available at: 32 <http://sourceforge.net/projects/acpi> 33 34 Linux support for ACPI is based on Intel Corporation's ACPI 35 Component Architecture (ACPI CA). For more information see: 36 <http://developer.intel.com/technology/iapc/acpi> 37 38 ACPI is an open industry specification co-developed by Compaq, 39 Intel, Microsoft, Phoenix, and Toshiba. The specification is 40 available at: 41 <http://www.acpi.info> 42 43if ACPI 44 45config ACPI_BOOT 46 bool 47 default y 48 49config ACPI_INTERPRETER 50 bool 51 depends on !IA64_SGI_SN 52 default y 53 54if ACPI_INTERPRETER 55 56config ACPI_SLEEP 57 bool "Sleep States (EXPERIMENTAL)" 58 depends on X86 59 depends on EXPERIMENTAL && PM 60 default y 61 ---help--- 62 This option adds support for ACPI suspend states. 63 64 With this option, you will be able to put the system "to sleep". 65 Sleep states are low power states for the system and devices. 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_AC 83 tristate "AC Adapter" 84 depends on X86 85 default m 86 help 87 This driver adds support for the AC Adapter object, which indicates 88 whether a system is on AC, or not. Typically, only mobile systems 89 have this object, since desktops are always on AC. 90 91config ACPI_BATTERY 92 tristate "Battery" 93 depends on X86 94 default m 95 help 96 This driver adds support for battery information through 97 /proc/acpi/battery. If you have a mobile system with a battery, 98 say Y. 99 100config ACPI_BUTTON 101 tristate "Button" 102 depends on !IA64_SGI_SN 103 default m 104 help 105 This driver registers for events based on buttons, such as the 106 power, sleep, and lid switch. In the future, a daemon will read 107 /proc/acpi/event and perform user-defined actions such as shutting 108 down the system. Until then, you can cat it, and see output when 109 a button is pressed. 110 111config ACPI_VIDEO 112 tristate "Video" 113 depends on EXPERIMENTAL 114 depends on !IA64_SGI_SN 115 default m 116 help 117 This driver implement the ACPI Extensions For Display Adapters 118 for integrated graphics devices on motherboard, as specified in 119 ACPI 2.0 Specification, Appendix B, allowing to perform some basic 120 control like defining the video POST device, retrieving EDID information 121 or to setup a video output, etc. 122 Note that this is an ref. implementation only. It may or may not work 123 for your integrated video device. 124 125config ACPI_FAN 126 tristate "Fan" 127 depends on !IA64_SGI_SN 128 default m 129 help 130 This driver adds support for ACPI fan devices, allowing user-mode 131 applications to perform basic fan control (on, off, status). 132 133config ACPI_PROCESSOR 134 tristate "Processor" 135 depends on !IA64_SGI_SN 136 default m 137 help 138 This driver installs ACPI as the idle handler for Linux, and uses 139 ACPI C2 and C3 processor states to save power, on systems that 140 support it. 141 142config ACPI_HOTPLUG_CPU 143 bool "Processor Hotplug (EXPERIMENTAL)" 144 depends on ACPI_PROCESSOR && HOTPLUG_CPU && EXPERIMENTAL 145 depends on !IA64_SGI_SN 146 select ACPI_CONTAINER 147 default n 148 ---help--- 149 Select this option if your platform support physical CPU hotplug. 150 151config ACPI_THERMAL 152 tristate "Thermal Zone" 153 depends on ACPI_PROCESSOR 154 default m 155 help 156 This driver adds support for ACPI thermal zones. Most mobile and 157 some desktop systems support ACPI thermal zones. It is HIGHLY 158 recommended that this option be enabled, as your processor(s) 159 may be damaged without it. 160 161config ACPI_NUMA 162 bool "NUMA support" 163 depends on NUMA 164 depends on (IA64 || X86_64) 165 default y if IA64_GENERIC || IA64_SGI_SN2 166 167config ACPI_ASUS 168 tristate "ASUS/Medion Laptop Extras" 169 depends on X86 170 default m 171 ---help--- 172 This driver provides support for extra features of ACPI-compatible 173 ASUS laptops. As some of Medion laptops are made by ASUS, it may also 174 support some Medion laptops (such as 9675 for example). It makes all 175 the extra buttons generate standard ACPI events that go through 176 /proc/acpi/events, and (on some models) adds support for changing the 177 display brightness and output, switching the LCD backlight on and off, 178 and most importantly, allows you to blink those fancy LEDs intended 179 for reporting mail and wireless status. 180 181 Note: display switching code is currently considered EXPERIMENTAL, 182 toying with these values may even lock your machine. 183 184 All settings are changed via /proc/acpi/asus directory entries. Owner 185 and group for these entries can be set with asus_uid and asus_gid 186 parameters. 187 188 More information and a userspace daemon for handling the extra buttons 189 at <http://sourceforge.net/projects/acpi4asus/>. 190 191 If you have an ACPI-compatible ASUS laptop, say Y or M here. This 192 driver is still under development, so if your laptop is unsupported or 193 something works not quite as expected, please use the mailing list 194 available on the above page (acpi4asus-user@lists.sourceforge.net) 195 196config ACPI_IBM 197 tristate "IBM ThinkPad Laptop Extras" 198 depends on X86 199 default m 200 ---help--- 201 This is a Linux ACPI driver for the IBM ThinkPad laptops.

These laptops can be recognized by 216 their lack of a BIOS setup menu and APM support. 217 218 On these machines, all system configuration is handled through the 219 ACPI. This driver is required for access to controls not covered 220 by the general ACPI drivers, such as LCD brightness, video output, 221 etc. 222 223 This driver differs from the non-ACPI Toshiba laptop driver (located 224 under "Processor type and features") in several aspects. 225 Configuration is accessed by reading and writing text files in the 226 /proc tree instead of by program interface to /dev. Furthermore, no 227 power management functions are exposed, as those are handled by the 228 general ACPI drivers. 229 230 More information about this driver is available at 231 <http://memebeam.org/toys/ToshibaAcpiDriver>. 232 233 If you have a legacy free Toshiba laptop (such as the Libretto L1 234 series), say Y. 235 236config ACPI_CUSTOM_DSDT 237 bool "Include Custom DSDT" 238 depends on !STANDALONE 239 default n 240 help 241 Thist option is to load a custom ACPI DSDT 242 If you don't know what that is, say N. 243 244config ACPI_CUSTOM_DSDT_FILE 245 string "Custom DSDT Table file to include" 246 depends on ACPI_CUSTOM_DSDT 247 default "" 248 help 249 Enter the full path name to the file wich includes the AmlCode declaration. 250 251config ACPI_BLACKLIST_YEAR 252 int "Disable ACPI for systems before Jan 1st this year" 253 depends on ACPI_INTERPRETER 254 default 0 255 help 256 enter a 4-digit year, eg. 2001 to disable ACPI by default 257 on platforms with DMI BIOS date before January 1st that year. 258 "acpi=force" can be used to override this mechanism. 259 260 Enter 0 to disable this mechanism and allow ACPI to 261 run by default no matter what the year.
