Advanced Configuration and Power Interface (ACPI) support for
|
|
Linux requires an ACPI-compliant platform (hardware/firmware),
|
|
and assumes the presence of OS-directed configuration and power
|
|
management (OSPM) software. This option will enlarge your
|
|
kernel by about 70K.
|
|
|
|
Linux ACPI provides a robust functional replacement for several
|
|
legacy configuration and power management interfaces, including
|
|
the Plug-and-Play BIOS specification (PnP BIOS), the
|
|
MultiProcessor Specification (MPS), and the Advanced Power
|
|
Management (APM) specification. If both ACPI and APM support
|
|
are configured, ACPI is used.
|
|
|
|
The project home page for the Linux ACPI subsystem is here:
|
|
<https://01.org/linux-acpi>
|
|
|
|
Linux support for ACPI is based on Intel Corporation's ACPI
|
|
Component Architecture (ACPI CA). For more information on the
|
|
ACPI CA, see:
|
|
<http://acpica.org/>
|
|
|
|
ACPI is an open industry specification originally co-developed by
|
|
Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba. Currently,
|
|
it is developed by the ACPI Specification Working Group (ASWG) under
|
|
the UEFI Forum and any UEFI member can join the ASWG and contribute
|
|
to the ACPI specification.
|
|
The specification is available at:
|
|

|

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

Say N to disable Embedded Controller /sys/kernel/debug interface

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

This config item changes the way the ACPI code is built. When this
|
|
option is selected, the kernel will use a specialized version of
|
|
ACPICA that ONLY supports the ACPI "reduced hardware" mode. The
|
|
resulting kernel will be smaller but it will also be restricted to
|
|
running in ACPI reduced hardware mode ONLY.
|
|
|
|
If you are unsure what to do, do not enable this option.

|
Certain usages such as Predictive Failure Analysis (PFA) require
|
|
more information about the error than what can be described in
|
|
processor machine check banks. Most server processors log
|
|
additional information about the error in processor uncore
|
|
registers. Since the addresses and layout of these registers vary
|
|
widely from one processor to another, system software cannot
|
|
readily make use of them. To complicate matters further, some of
|
|
the additional error information cannot be constructed without
|
|
detailed knowledge about platform topology.
|
|
|
|
Enhanced MCA Logging allows firmware to provide additional error
|
|
information to system software, synchronous with MCE or CMCI. This
|
|
driver adds support for that functionality with corresponding
|
|
tracepoint which carries that information to userspace.
