1da177e4 | 16 | Advanced Configuration and Power Interface (ACPI) support for |
1c48aa36 | 17 | Linux requires an ACPI-compliant platform (hardware/firmware), |
1da177e4 LT |
18 | and assumes the presence of OS-directed configuration and power |
19 | management (OSPM) software. 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 | |
1c48aa36 | 27 | are configured, ACPI is used. |
1da177e4 | 28 | |

aaf3d29f | 30 | <https://01.org/linux-acpi> |
1da177e4 LT |
31 | |
32 | Linux support for ACPI is based on Intel Corporation's ACPI | |
1c48aa36 BH |
33 | Component Architecture (ACPI CA). For more information on the |
34 | ACPI CA, see: | |

37 | ACPI is an open industry specification originally co-developed by |
38 | Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba. Currently, | |
39 | it is developed by the ACPI Specification Working Group (ASWG) under | |
40 | the UEFI Forum and any UEFI member can join the ASWG and contribute | |
41 | to the ACPI specification. | |
1c48aa36 | 42 | The specification is available at: |

118 | help | |
119 | The platform firmware on some systems expects Linux to return "5" as | |
120 | the supported ACPI revision which makes it expose system configuration | |
121 | information in a special way. | |
122 | ||
123 | For example, based on what ACPI exports as the supported revision, | |
124 | Dell XPS 13 (2015) configures its audio device to either work in HDA | |
125 | mode or in I2S mode, where the former is supposed to be used on Linux | |
126 | until the latter is fully supported (in the kernel as well as in user | |
127 | space). | |
128 | ||
129 | This option enables a DMI-based quirk for the above Dell machine (so | |
130 | that HDA audio is exposed by the platform firmware to the kernel) and | |
131 | makes it possible to force the kernel to return "5" as the supported | |
132 | ACPI revision via the "acpi_rev_override" command line switch. | |

500de3dd TR |
140 | Be aware that using this interface can confuse your Embedded |
141 | Controller in a way that a normal reboot is not enough. You then | |
25cb1bfd | 142 | have to power off your system, and remove the laptop battery for |
500de3dd | 143 | some seconds. |
1195a098 TR |
144 | An Embedded Controller typically is available on laptops and reads |
145 | sensor values like battery state and temperature. | |
500de3dd TR |
146 | The kernel accesses the EC through ACPI parsed code provided by BIOS |
147 | tables. This option allows to access the EC directly without ACPI | |
148 | code being involved. | |
1195a098 TR |
149 | Thus this option is a debug option that helps to write ACPI drivers |
150 | and can be used to identify ACPI code or EC firmware bugs. | |

484 | Certain usages such as Predictive Failure Analysis (PFA) require | |
485 | more information about the error than what can be described in | |
486 | processor machine check banks. Most server processors log | |
487 | additional information about the error in processor uncore | |
488 | registers. Since the addresses and layout of these registers vary | |
489 | widely from one processor to another, system software cannot | |
490 | readily make use of them. To complicate matters further, some of | |
491 | the additional error information cannot be constructed without | |
