config ARM_PSCI_FW
bool
config ARM_PSCI_CHECKER
bool "ARM PSCI checker"
depends on ARM_PSCI_FW && HOTPLUG_CPU && CPU_IDLE && !TORTURE_TEST
help
Run the PSCI checker during startup. This checks that hotplug and
suspend operations work correctly when using PSCI.
The torture tests may interfere with the PSCI checker by turning CPUs
on and off through hotplug, so for now torture tests and PSCI checker
are mutually exclusive.
config ARM_SCPI_PROTOCOL
tristate "ARM System Control and Power Interface (SCPI) Message Protocol"
depends on ARM || ARM64 || COMPILE_TEST
depends on MAILBOX
help
System Control and Power Interface (SCPI) Message Protocol is
defined for the purpose of communication between the Application
Cores(AP) and the System Control Processor(SCP). The MHU peripheral
provides a mechanism for inter-processor communication between SCP
and AP.
SCP controls most of the power managament on the Application
Processors. It offers control and management of: the core/cluster
power states, various power domain DVFS including the core/cluster,
certain system clocks configuration, thermal sensors and many
others.
This protocol library provides interface for all the client drivers
making use of the features offered by the SCP.
config ARM_SCPI_POWER_DOMAIN
tristate "SCPI power domain driver"
depends on ARM_SCPI_PROTOCOL || (COMPILE_TEST && OF)
default y
select PM_GENERIC_DOMAINS if PM
help
This enables support for the SCPI power domains which can be
enabled or disabled via the SCP firmware
config ARM_SDE_INTERFACE
bool "ARM Software Delegated Exception Interface (SDEI)"
depends on ARM64
help
The Software Delegated Exception Interface (SDEI) is an ARM
standard for registering callbacks from the platform firmware
into the OS. This is typically used to implement RAS notifications.
config EDD
tristate "BIOS Enhanced Disk Drive calls determine boot disk"
depends on X86
help
Say Y or M here if you want to enable BIOS Enhanced Disk Drive
Services real mode BIOS calls to determine which disk
BIOS tries boot from. This information is then exported via sysfs.
This option is experimental and is known to fail to boot on some
obscure configurations. Most disk controller BIOS vendors do
not yet implement this feature.
config EDD_OFF
bool "Sets default behavior for EDD detection to off"
depends on EDD
default n
help
Say Y if you want EDD disabled by default, even though it is compiled into the
kernel. Say N if you want EDD enabled by default. EDD can be dynamically set
using the kernel parameter 'edd={on|skipmbr|off}'.
config FIRMWARE_MEMMAP
bool "Add firmware-provided memory map to sysfs" if EXPERT
default X86
help
Add the firmware-provided (unmodified) memory map to /sys/firmware/memmap.
That memory map is used for example by kexec to set up parameter area
for the next kernel, but can also be used for debugging purposes.
See also Documentation/ABI/testing/sysfs-firmware-memmap.
config EFI_PCDP
bool "Console device selection via EFI PCDP or HCDP table"
depends on ACPI && EFI && IA64
default y if IA64
help
If your firmware supplies the PCDP table, and you want to
automatically use the primary console device it describes
as the Linux console, say Y here.
If your firmware supplies the HCDP table, and you want to
use the first serial port it describes as the Linux console,
say Y here. If your EFI ConOut path contains only a UART
device, it will become the console automatically. Otherwise,
you must specify the "console=hcdp" kernel boot argument.
Neither the PCDP nor the HCDP affects naming of serial devices,
so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
on how the driver discovers devices.
You must also enable the appropriate drivers (serial, VGA, etc.)
See DIG64_HCDPv20_042804.pdf available from
<http://www.dig64.org/specifications/>
config DELL_RBU
tristate "BIOS update support for DELL systems via sysfs"
depends on X86
select FW_LOADER
select FW_LOADER_USER_HELPER
help
Say m if you want to have the option of updating the BIOS for your
DELL system. Note you need a Dell OpenManage or Dell Update package (DUP)
supporting application to communicate with the BIOS regarding the new
image for the image update to take effect.
See <file:Documentation/dell_rbu.txt> for more details on the driver.
config DCDBAS
tristate "Dell Systems Management Base Driver"
depends on X86
help
The Dell Systems Management Base Driver provides a sysfs interface
for systems management software to perform System Management
Interrupts (SMIs) and Host Control Actions (system power cycle or
power off after OS shutdown) on certain Dell systems.
See <file:Documentation/dcdbas.txt> for more details on the driver
and the Dell systems on which Dell systems management software makes
use of this driver.
Say Y or M here to enable the driver for use by Dell systems
management software such as Dell OpenManage.
config DMIID
bool "Export DMI identification via sysfs to userspace"
depends on DMI
default y
help
Say Y here if you want to query SMBIOS/DMI system identification
information from userspace through /sys/class/dmi/id/ or if you want
DMI-based module auto-loading.
config DMI_SYSFS
tristate "DMI table support in sysfs"
depends on SYSFS && DMI
default n
help
Say Y or M here to enable the exporting of the raw DMI table
data via sysfs. This is useful for consuming the data without
requiring any access to /dev/mem at all. Tables are found
under /sys/firmware/dmi when this option is enabled and
loaded.
config DMI_SCAN_MACHINE_NON_EFI_FALLBACK
bool
config ISCSI_IBFT_FIND
bool "iSCSI Boot Firmware Table Attributes"
depends on X86 && ACPI
default n
help
This option enables the kernel to find the region of memory
in which the ISCSI Boot Firmware Table (iBFT) resides. This
is necessary for iSCSI Boot Firmware Table Attributes module to work
properly.
config ISCSI_IBFT
tristate "iSCSI Boot Firmware Table Attributes module"
select ISCSI_BOOT_SYSFS
depends on ISCSI_IBFT_FIND && SCSI && SCSI_LOWLEVEL
default n
help
This option enables support for detection and exposing of iSCSI
Boot Firmware Table (iBFT) via sysfs to userspace. If you wish to
detect iSCSI boot parameters dynamically during system boot, say Y.
Otherwise, say N.
config RASPBERRYPI_FIRMWARE
tristate "Raspberry Pi Firmware Driver"
depends on BCM2835_MBOX
help
This option enables support for communicating with the firmware on the
Raspberry Pi.
config FW_CFG_SYSFS
tristate "QEMU fw_cfg device support in sysfs"
depends on SYSFS && (ARM || ARM64 || PPC_PMAC || SPARC || X86)
depends on HAS_IOPORT_MAP
default n
help
Say Y or M here to enable the exporting of the QEMU firmware
configuration (fw_cfg) file entries via sysfs. Entries are
found under /sys/firmware/fw_cfg when this option is enabled
and loaded.
config FW_CFG_SYSFS_CMDLINE
bool "QEMU fw_cfg device parameter parsing"
depends on FW_CFG_SYSFS
help
Allow the qemu_fw_cfg device to be initialized via the kernel
command line or using a module parameter.
WARNING: Using incorrect parameters (base address in particular)
may crash your system.
config QCOM_SCM
bool
depends on ARM || ARM64
select RESET_CONTROLLER
config QCOM_SCM_32
def_bool y
depends on QCOM_SCM && ARM
config QCOM_SCM_64
def_bool y
depends on QCOM_SCM && ARM64
config QCOM_SCM_DOWNLOAD_MODE_DEFAULT
bool "Qualcomm download mode enabled by default"
depends on QCOM_SCM
help
A device with "download mode" enabled will upon an unexpected
warm-restart enter a special debug mode that allows the user to
"download" memory content over USB for offline postmortem analysis.
The feature can be enabled/disabled on the kernel command line.
Say Y here to enable "download mode" by default.
config TI_SCI_PROTOCOL
tristate "TI System Control Interface (TISCI) Message Protocol"
depends on TI_MESSAGE_MANAGER
help
TI System Control Interface (TISCI) Message Protocol is used to manage
compute systems such as ARM, DSP etc with the system controller in
complex System on Chip(SoC) such as those found on certain keystone
generation SoC from TI.
System controller provides various facilities including power
management function support.
This protocol library is used by client drivers to use the features
provided by the system controller.
