Linus Torvalds 88793e5c77 The libnvdimm sub-system introduces, in addition to the libnvdimm-core, 
4 drivers / enabling modules:
 
 NFIT:
 Instantiates an "nvdimm bus" with the core and registers memory devices
 (NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware Interface
 table).  After registering NVDIMMs the NFIT driver then registers
 "region" devices.  A libnvdimm-region defines an access mode and the
 boundaries of persistent memory media.  A region may span multiple
 NVDIMMs that are interleaved by the hardware memory controller.  In
 turn, a libnvdimm-region can be carved into a "namespace" device and
 bound to the PMEM or BLK driver which will attach a Linux block device
 (disk) interface to the memory.
 
 PMEM:
 Initially merged in v4.1 this driver for contiguous spans of persistent
 memory address ranges is re-worked to drive PMEM-namespaces emitted by
 the libnvdimm-core.  In this update the PMEM driver, on x86, gains the
 ability to assert that writes to persistent memory have been flushed all
 the way through the caches and buffers in the platform to persistent
 media.  See memcpy_to_pmem() and wmb_pmem().
 
 BLK:
 This new driver enables access to persistent memory media through "Block
 Data Windows" as defined by the NFIT.  The primary difference of this
 driver to PMEM is that only a small window of persistent memory is
 mapped into system address space at any given point in time.  Per-NVDIMM
 windows are reprogrammed at run time, per-I/O, to access different
 portions of the media.  BLK-mode, by definition, does not support DAX.
 
 BTT:
 This is a library, optionally consumed by either PMEM or BLK, that
 converts a byte-accessible namespace into a disk with atomic sector
 update semantics (prevents sector tearing on crash or power loss).  The
 sinister aspect of sector tearing is that most applications do not know
 they have a atomic sector dependency.  At least today's disk's rarely
 ever tear sectors and if they do one almost certainly gets a CRC error
 on access.  NVDIMMs will always tear and always silently.  Until an
 application is audited to be robust in the presence of sector-tearing
 the usage of BTT is recommended.

select PNP
default y
help
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:
<http://www.acpi.info>

For backwards compatibility, this option allows
deprecated power /proc/acpi/ directories to exist, even when
they have been replaced by functions in /sys.
The deprecated directories (and their replacements) include:
/proc/acpi/battery/* (/sys/class/power_supply/*)
/proc/acpi/ac_adapter/* (sys/class/power_supply/*)
This option has no effect on /proc/acpi/ directories
and functions, which do not yet exist in /sys
This option, together with the proc directories, will be
deleted in the future.

help
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.
config ACPI_AC
tristate "AC Adapter"
depends on X86
select POWER_SUPPLY
default y
help
This driver supports the AC Adapter object, which indicates
whether a system is on AC or not. If you have a system that can

help
This driver handles events on the power, sleep, and lid buttons.
A daemon reads events from input devices or via netlink and
performs user-defined actions such as shutting down the system.
This is necessary for software-controlled poweroff.
To compile this driver as a module, choose M here:
the module will be called button.
config ACPI_VIDEO
tristate "Video"
depends on X86 && BACKLIGHT_CLASS_DEVICE

help
This driver installs ACPI as the idle handler for Linux and uses
ACPI C2 and C3 processor states to save power on systems that
support it. It is required by several flavors of cpufreq
performance-state drivers.
To compile this driver as a module, choose M here:
the module will be called processor.
config ACPI_IPMI
tristate "IPMI"
depends on IPMI_SI
default n
help
This driver enables the ACPI to access the BMC controller. And it
uses the IPMI request/response message to communicate with BMC
controller, which can be found on on the server.
To compile this driver as a module, choose M here:
the module will be called as acpi_ipmi.

select ACPI_CONTAINER
default y
config ACPI_PROCESSOR_AGGREGATOR
tristate "Processor Aggregator"
depends on ACPI_PROCESSOR
depends on X86
help
ACPI 4.0 defines processor Aggregator, which enables OS to perform
specific processor configuration and control that applies to all
processors in the platform. Currently only logical processor idling
is defined, which is to reduce power consumption. This driver
supports the new device.
config ACPI_THERMAL
tristate "Thermal Zone"
depends on ACPI_PROCESSOR
select THERMAL
default y
help
This driver supports ACPI thermal zones. Most mobile and
some desktop systems support ACPI thermal zones. It is HIGHLY
recommended that this option be enabled, as your processor(s)
may be damaged without it.

config ACPI_INITRD_TABLE_OVERRIDE
bool "ACPI tables override via initrd"
depends on BLK_DEV_INITRD && X86
default n
help
This option provides functionality to override arbitrary ACPI tables
via initrd. No functional change if no ACPI tables are passed via
initrd, therefore it's safe to say Y.
See Documentation/acpi/initrd_table_override.txt for details
config ACPI_DEBUG
bool "Debug Statements"
default n
help
The ACPI subsystem can produce debug output. Saying Y enables this
output and increases the kernel size by around 50K.
Use the acpi.debug_layer and acpi.debug_level kernel command-line
parameters documented in Documentation/acpi/debug.txt and
Documentation/kernel-parameters.txt to control the type and
amount of debug output.
config ACPI_PCI_SLOT
bool "PCI slot detection driver"
depends on SYSFS
default n
help
This driver creates entries in /sys/bus/pci/slots/ for all PCI
slots in the system. This can help correlate PCI bus addresses,
i.e., segment/bus/device/function tuples, with physical slots in
the system. If you are unsure, say N.
config X86_PM_TIMER
bool "Power Management Timer Support" if EXPERT
depends on X86
default y
help
The Power Management Timer is available on all ACPI-capable,
in most cases even if ACPI is unusable or blacklisted.
This timing source is not affected by power management features
like aggressive processor idling, throttling, frequency and/or
voltage scaling, unlike the commonly used Time Stamp Counter
(TSC) timing source.
You should nearly always say Y here because many modern
systems require this timer.
config ACPI_CONTAINER
bool "Container and Module Devices"
default (ACPI_HOTPLUG_MEMORY || ACPI_HOTPLUG_CPU)
help
This driver supports ACPI Container and Module devices (IDs
ACPI0004, PNP0A05, and PNP0A06).
This helps support hotplug of nodes, CPUs, and memory.
To compile this driver as a module, choose M here:
the module will be called container.
config ACPI_HOTPLUG_MEMORY
bool "Memory Hotplug"
depends on MEMORY_HOTPLUG
help
This driver supports ACPI memory hotplug. The driver
fields notifications on ACPI memory devices (PNP0C80),
which represent memory ranges that may be onlined or
offlined during runtime.
If your hardware and firmware do not support adding or
removing memory devices at runtime, you need not enable
this driver.
To compile this driver as a module, choose M here:
the module will be called acpi_memhotplug.
config ACPI_HOTPLUG_IOAPIC
bool
depends on PCI
depends on X86_IO_APIC

help
This driver supports the Hardware Error Device (PNP0C33),
which is used to report some hardware errors notified via
SCI, mainly the corrected errors.
config ACPI_CUSTOM_METHOD
tristate "Allow ACPI methods to be inserted/replaced at run time"
depends on DEBUG_FS
default n
help
This debug facility allows ACPI AML methods to be inserted and/or
replaced without rebooting the system. For details refer to:
Documentation/acpi/method-customizing.txt.
NOTE: This option is security sensitive, because it allows arbitrary
kernel memory to be written to by root (uid=0) users, allowing them
to bypass certain security measures (e.g. if root is not allowed to
load additional kernel modules after boot, this feature may be used
to override that restriction).
config ACPI_BGRT
bool "Boottime Graphics Resource Table support"
depends on EFI && X86
help
This driver adds support for exposing the ACPI Boottime Graphics
Resource Table, which allows the operating system to obtain
data from the firmware boot splash. It will appear under
/sys/firmware/acpi/bgrt/ .
config ACPI_REDUCED_HARDWARE_ONLY
bool "Hardware-reduced ACPI support only" if EXPERT
def_bool n
help
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.

device and its children. This can be very verbose, so leave
it disabled unless you are debugging a hardware / firmware
issue.

config ACPI_EXTLOG
tristate "Extended Error Log support"
depends on X86_MCE && X86_LOCAL_APIC
select UEFI_CPER
select RAS
default n
help
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.
menuconfig PMIC_OPREGION
