1da177e4 | 13 | Advanced Configuration and Power Interface (ACPI) support for |
1c48aa36 | 14 | Linux requires an ACPI-compliant platform (hardware/firmware), |
1da177e4 LT |
15 | and assumes the presence of OS-directed configuration and power |
16 | management (OSPM) software. This option will enlarge your | |
17 | kernel by about 70K. | |
18 | ||
19 | Linux ACPI provides a robust functional replacement for several | |
20 | legacy configuration and power management interfaces, including | |
21 | the Plug-and-Play BIOS specification (PnP BIOS), the | |
22 | MultiProcessor Specification (MPS), and the Advanced Power | |
23 | Management (APM) specification. If both ACPI and APM support | |
1c48aa36 | 24 | are configured, ACPI is used. |
1da177e4 | 25 | |
1c48aa36 | 26 | The project home page for the Linux ACPI subsystem is here: |
aaf3d29f | 27 | <https://01.org/linux-acpi> |
1da177e4 LT |
28 | |
29 | Linux support for ACPI is based on Intel Corporation's ACPI | |
1c48aa36 BH |
30 | Component Architecture (ACPI CA). For more information on the |
31 | ACPI CA, see: | |

34 | ACPI is an open industry specification originally co-developed by |
35 | Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba. Currently, | |
36 | it is developed by the ACPI Specification Working Group (ASWG) under | |
37 | the UEFI Forum and any UEFI member can join the ASWG and contribute | |
38 | to the ACPI specification. | |
1c48aa36 | 39 | The specification is available at: |

107 | help | |
108 | The platform firmware on some systems expects Linux to return "5" as | |
109 | the supported ACPI revision which makes it expose system configuration | |
110 | information in a special way. | |
111 | ||
112 | For example, based on what ACPI exports as the supported revision, | |
113 | Dell XPS 13 (2015) configures its audio device to either work in HDA | |
114 | mode or in I2S mode, where the former is supposed to be used on Linux | |
115 | until the latter is fully supported (in the kernel as well as in user | |
116 | space). | |
117 | ||
118 | This option enables a DMI-based quirk for the above Dell machine (so | |
119 | that HDA audio is exposed by the platform firmware to the kernel) and | |
120 | makes it possible to force the kernel to return "5" as the supported | |
121 | ACPI revision via the "acpi_rev_override" command line switch. | |

129 | Be aware that using this interface can confuse your Embedded |
130 | Controller in a way that a normal reboot is not enough. You then | |
25cb1bfd | 131 | have to power off your system, and remove the laptop battery for |
500de3dd | 132 | some seconds. |
1195a098 TR |
133 | An Embedded Controller typically is available on laptops and reads |
134 | sensor values like battery state and temperature. | |
500de3dd TR |
135 | The kernel accesses the EC through ACPI parsed code provided by BIOS |
136 | tables. This option allows to access the EC directly without ACPI | |
137 | code being involved. | |
1195a098 TR |
138 | Thus this option is a debug option that helps to write ACPI drivers |
139 | and can be used to identify ACPI code or EC firmware bugs. | |

430 | NOTE: This option is security sensitive, because it allows arbitrary | |
431 | kernel memory to be written to by root (uid=0) users, allowing them | |

433 | load additional kernel modules after boot, this feature may be used | |

449 | This config item changes the way the ACPI code is built. When this |
450 | option is selected, the kernel will use a specialized version of | |
451 | ACPICA that ONLY supports the ACPI "reduced hardware" mode. The | |
452 | resulting kernel will be smaller but it will also be restricted to | |
453 | running in ACPI reduced hardware mode ONLY. | |

468 | help | |
469 | Certain usages such as Predictive Failure Analysis (PFA) require | |
470 | more information about the error than what can be described in | |
471 | processor machine check banks. Most server processors log | |
472 | additional information about the error in processor uncore | |
473 | registers. Since the addresses and layout of these registers vary | |
474 | widely from one processor to another, system software cannot | |
475 | readily make use of them. To complicate matters further, some of | |
476 | the additional error information cannot be constructed without | |
477 | detailed knowledge about platform topology. | |
