This option will enlarge your 22 kernel by about 70K. 23 24 Linux ACPI provides a robust functional replacement for several 25 legacy configuration and power management interfaces, including 26 the Plug-and-Play BIOS specification (PnP BIOS), the 27 MultiProcessor Specification (MPS), and the Advanced Power 28 Management (APM) specification. If both ACPI and APM support 29 are configured, whichever is loaded first shall be used. 30 31 The ACPI SourceForge project contains the latest source code, 32 documentation, tools, mailing list subscription, and other 33 information. This project is available at: 34 <http://sourceforge.net/projects/acpi> 35 36 Linux support for ACPI is based on Intel Corporation's ACPI 37 Component Architecture (ACPI CA). For more information see: 38 <http://developer.intel.com/technology/iapc/acpi> 39 40 ACPI is an open industry specification co-developed by Compaq, 41 Intel, Microsoft, Phoenix, and Toshiba. The specification is 42 available at: 43 <http://www.acpi.info> 44 45if ACPI 46 47config ACPI_SLEEP 48 bool "Sleep States" 49 depends on X86 && (!SMP || SUSPEND_SMP) 50 depends on PM 51 default y 52 ---help--- 53 This option adds support for ACPI suspend states. 54 55 With this option, you will be able to put the system "to sleep". 56 Sleep states are low power states for the system and devices. All 57 of the system operating state is saved to either memory or disk 58 (depending on the state), to allow the system to resume operation 59 quickly at your request. 60 61 Although this option sounds really nifty, barely any of the device 62 drivers have been converted to the new driver model and hence few 63 have proper power management support. 64 65 This option is not recommended for anyone except those doing driver 66 power management development. 67 68config ACPI_SLEEP_PROC_FS 69 bool 70 depends on ACPI_SLEEP && PROC_FS 71 default y 72 73config ACPI_SLEEP_PROC_SLEEP 74 bool "/proc/acpi/sleep (deprecated)" 75 depends on ACPI_SLEEP_PROC_FS 76 default n 77 ---help--- 78 Create /proc/acpi/sleep 79 Deprecated by /sys/power/state 80 81config ACPI_PROCFS 82 bool "Procfs interface (deprecated)" 83 depends on ACPI 84 default y 85 ---help--- 86 Procfs interface for ACPI is made optional for back-compatible. 87 As the same functions are duplicated in sysfs interface 88 and this proc interface will be removed some time later, 89 it's marked as deprecated. 90 ( /proc/acpi/debug_layer && debug_level are deprecated by 91 /sys/module/acpi/parameters/debug_layer && debug_level. 92 /proc/acpi/info is deprecated by 93 /sys/module/acpi/parameters/acpica_version ) 94 95config ACPI_AC 96 tristate "AC Adapter" 97 depends on X86 98 default y 99 help 100 This driver adds support for the AC Adapter object, which indicates 101 whether a system is on AC, or not. If you have a system that can 102 switch between A/C and battery, say Y. 103 104config ACPI_BATTERY 105 tristate "Battery" 106 depends on X86 107 default y 108 help 109 This driver adds support for battery information through 110 /proc/acpi/battery. If you have a mobile system with a battery, 111 say Y. 112 113config ACPI_BUTTON 114 tristate "Button" 115 depends on INPUT 116 default y 117 help 118 This driver handles events on the power, sleep and lid buttons. 119 A daemon reads /proc/acpi/event and perform user-defined actions 120 such as shutting down the system. This is necessary for 121 software controlled poweroff. 122 123config ACPI_VIDEO 124 tristate "Video" 125 depends on X86 && BACKLIGHT_CLASS_DEVICE 126 help 127 This driver implement the ACPI Extensions For Display Adapters 128 for integrated graphics devices on motherboard, as specified in 129 ACPI 2.0 Specification, Appendix B, allowing to perform some basic 130 control like defining the video POST device, retrieving EDID information 131 or to setup a video output, etc. 132 Note that this is an ref. implementation only. It may or may not work 133 for your integrated video device. 134 135config ACPI_HOTKEY 136 tristate "Generic Hotkey (EXPERIMENTAL)" 137 depends on EXPERIMENTAL 138 depends on X86 139 default n 140 help 141 Experimental consolidated hotkey driver. 142 If you are unsure, say N. 143 144config ACPI_FAN 145 tristate "Fan" 146 default y 147 help 148 This driver adds support for ACPI fan devices, allowing user-mode 149 applications to perform basic fan control (on, off, status). 150 151config ACPI_DOCK 152 tristate "Dock" 153 depends on EXPERIMENTAL 154 help 155 This driver adds support for ACPI controlled docking stations 156 157config ACPI_BAY 158 tristate "Removable Drive Bay (EXPERIMENTAL)" 159 depends on EXPERIMENTAL 160 help 161 This driver adds support for ACPI controlled removable drive 162 bays such as the IBM ultrabay or the Dell Module Bay. 163 164config ACPI_PROCESSOR 165 tristate "Processor" 166 default y 167 help 168 This driver installs ACPI as the idle handler for Linux, and uses 169 ACPI C2 and C3 processor states to save power, on systems that 170 support it. It is required by several flavors of cpufreq 171 Performance-state drivers. 172 173config ACPI_HOTPLUG_CPU 174 bool 175 depends on ACPI_PROCESSOR && HOTPLUG_CPU 176 select ACPI_CONTAINER 177 default y 178 179config ACPI_THERMAL 180 tristate "Thermal Zone" 181 depends on ACPI_PROCESSOR 182 default y 183 help 184 This driver adds support for ACPI thermal zones. Most mobile and 185 some desktop systems support ACPI thermal zones. It is HIGHLY 186 recommended that this option be enabled, as your processor(s) 187 may be damaged without it. 188 189config ACPI_NUMA 190 bool "NUMA support" 191 depends on NUMA 192 depends on (X86 || IA64) 193 default y if IA64_GENERIC || IA64_SGI_SN2 194 195config ACPI_ASUS 196 tristate "ASUS/Medion Laptop Extras" 197 depends on X86 198 select BACKLIGHT_CLASS_DEVICE 199 ---help--- 200 This driver provides support for extra features of ACPI-compatible 201 ASUS laptops. As some of Medion laptops are made by ASUS, it may also 202 support some Medion laptops (such as 9675 for example). It makes all 203 the extra buttons generate standard ACPI events that go through 204 /proc/acpi/events, and (on some models) adds support for changing the 205 display brightness and output, switching the LCD backlight on and off, 206 and most importantly, allows you to blink those fancy LEDs intended 207 for reporting mail and wireless status. 208 209 Note: display switching code is currently considered EXPERIMENTAL, 210 toying with these values may even lock your machine. 211 212 All settings are changed via /proc/acpi/asus directory entries. Owner 213 and group for these entries can be set with asus_uid and asus_gid 214 parameters. 215 216 More information and a userspace daemon for handling the extra buttons 217 at <http://sourceforge.net/projects/acpi4asus/>. 218 219 If you have an ACPI-compatible ASUS laptop, say Y or M here. This 220 driver is still under development, so if your laptop is unsupported or 221 something works not quite as expected, please use the mailing list 222 available on the above page (acpi4asus-user@lists.sourceforge.net). 223 224 NOTE: This driver is deprecated and will probably be removed soon, 225 use asus-laptop instead. 226 227config ACPI_IBM 228 tristate "IBM ThinkPad Laptop Extras" 229 depends on X86 230 select BACKLIGHT_CLASS_DEVICE 231 ---help--- 232 This is a Linux ACPI driver for the IBM ThinkPad laptops. It adds 233 support for Fn-Fx key combinations, Bluetooth control, video 234 output switching, ThinkLight control, UltraBay eject and more. 235 For more information about this driver see <file:Documentation/ibm-acpi.txt> 236 and <http://ibm-acpi.sf.net/> . 237 238 If you have an IBM ThinkPad laptop, say Y or M here. 239 240config ACPI_IBM_DOCK 241 bool "Legacy Docking Station Support" 242 depends on ACPI_IBM 243 depends on ACPI_DOCK=n 244 default n 245 ---help--- 246 Allows the ibm_acpi driver to handle docking station events. 247 This support is obsoleted by CONFIG_HOTPLUG_PCI_ACPI. It will 248 allow locking and removing the laptop from the docking station, 249 but will not properly connect PCI devices. 250 251 If you are not sure, say N here. 252 253config ACPI_TOSHIBA 254 tristate "Toshiba Laptop Extras" 255 depends on X86 256 select BACKLIGHT_CLASS_DEVICE 257 ---help--- 258 This driver adds support for access to certain system settings 259 on "legacy free" Toshiba laptops. These laptops can be recognized by 260 their lack of a BIOS setup menu and APM support. 261 262 On these machines, all system configuration is handled through the 263 ACPI. This driver is required for access to controls not covered 264 by the general ACPI drivers, such as LCD brightness, video output, 265 etc. 266 267 This driver differs from the non-ACPI Toshiba laptop driver (located 268 under "Processor type and features") in several aspects. 269 Configuration is accessed by reading and writing text files in the 270 /proc tree instead of by program interface to /dev. Furthermore, no 271 power management functions are exposed, as those are handled by the 272 general ACPI drivers. 273 274 More information about this driver is available at 275 <http://memebeam.org/toys/ToshibaAcpiDriver>. 276 277 If you have a legacy free Toshiba laptop (such as the Libretto L1 278 series), say Y. 279 280config ACPI_CUSTOM_DSDT 281 bool "Include Custom DSDT" 282 depends on !STANDALONE 283 default n 284 help 285 This option is to load a custom ACPI DSDT 286 If you don't know what that is, say N. 287 288config ACPI_CUSTOM_DSDT_FILE 289 string "Custom DSDT Table file to include" 290 depends on ACPI_CUSTOM_DSDT 291 default "" 292 help 293 Enter the full path name to the file which includes the AmlCode 294 declaration. 295 296config ACPI_BLACKLIST_YEAR 297 int "Disable ACPI for systems before Jan 1st this year" if X86_32 298 default 0 299 help 300 enter a 4-digit year, eg. 2001 to disable ACPI by default 301 on platforms with DMI BIOS date before January 1st that year. 302 "acpi=force" can be used to override this mechanism. 303 304 Enter 0 to disable this mechanism and allow ACPI to 305 run by default no matter what the year. (default) 306 307config ACPI_DEBUG 308 bool "Debug Statements" 309 default n 310 help 311 The ACPI driver can optionally report errors with a great deal 312 of verbosity. Saying Y enables these statements. This will increase 313 your kernel size by around 50K. 314 315config ACPI_EC 316 bool 317 default y 318 help 319 This driver is required on some systems for the proper operation of 320 the battery and thermal drivers.

This driver 370 provides support for fielding notifications on ACPI memory 371 devices (PNP0C80) which represent memory ranges that may be 372 onlined or offlined during runtime. 373 374 Enabling this driver assumes that your platform hardware 375 and firmware have support for hot-plugging physical memory. If 376 your system does not support physically adding or ripping out 377 memory DIMMs at some platform defined granularity (individually 378 or as a bank) at runtime, then you need not enable this driver. 379 380 If one selects "m," this driver can be loaded using the following 381 command: 382 $>modprobe acpi_memhotplug 383 384config ACPI_SBS 385 tristate "Smart Battery System (EXPERIMENTAL)" 386 depends on X86 && I2C 387 depends on EXPERIMENTAL 388 help 389 This driver adds support for the Smart Battery System. 390 Depends on I2C (Device Drivers ---> I2C support) 391 A "Smart Battery" is quite old and quite rare compared 392 to today's ACPI "Control Method" battery. 393 394endif # ACPI 395 396endmenu 397
