we share the same driver for both ACPI predefined Fan device and INT3404 Fan device, thus we should select the ACPI Fan driver when int340x thermal drivers are enabeld. Signed-off-by: Zhang Rui <rui.zhang@intel.com>

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:

For backwards compatibility, this option allows

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.

additional information about the error in processor uncore

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
