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 management 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_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 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 && ISCSI_IBFT
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
select ISCSI_IBFT_FIND if X86
depends on ACPI && 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 || PARISC || PPC_PMAC || RISCV || 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 INTEL_STRATIX10_SERVICE
tristate "Intel Stratix10 Service Layer"
depends on ARCH_INTEL_SOCFPGA && ARM64 && HAVE_ARM_SMCCC
default n
help
Intel Stratix10 service layer runs at privileged exception level,
interfaces with the service providers (FPGA manager is one of them)
and manages secure monitor call to communicate with secure monitor
software at secure monitor exception level.
Say Y here if you want Stratix10 service layer support.
config INTEL_STRATIX10_RSU
tristate "Intel Stratix10 Remote System Update"
depends on INTEL_STRATIX10_SERVICE
help
The Intel Remote System Update (RSU) driver exposes interfaces
access through the Intel Service Layer to user space via sysfs
device attribute nodes. The RSU interfaces report/control some of
the optional RSU features of the Stratix 10 SoC FPGA.
The RSU provides a way for customers to update the boot
configuration of a Stratix 10 SoC device with significantly reduced
risk of corrupting the bitstream storage and bricking the system.
Enable RSU support if you are using an Intel SoC FPGA with the RSU
feature enabled and you want Linux user space control.
Say Y here if you want Intel RSU support.
config MTK_ADSP_IPC
tristate "MTK ADSP IPC Protocol driver"
depends on MTK_ADSP_MBOX
help
Say yes here to add support for the MediaTek ADSP IPC
between host AP (Linux) and the firmware running on ADSP.
ADSP exists on some mtk processors.
Client might use shared memory to exchange information with ADSP.
config SYSFB
bool
select BOOT_VESA_SUPPORT
select SCREEN_INFO
config SYSFB_SIMPLEFB
bool "Mark VGA/VBE/EFI FB as generic system framebuffer"
depends on X86 || EFI
select SYSFB
help
Firmwares often provide initial graphics framebuffers so the BIOS,
bootloader or kernel can show basic video-output during boot for
user-guidance and debugging. Historically, x86 used the VESA BIOS
Extensions and EFI-framebuffers for this, which are mostly limited
to x86 BIOS or EFI systems.
This option, if enabled, marks VGA/VBE/EFI framebuffers as generic
framebuffers so the new generic system-framebuffer drivers can be
used instead. If the framebuffer is not compatible with the generic
modes, it is advertised as fallback platform framebuffer so legacy
drivers like efifb, vesafb and uvesafb can pick it up.
If this option is not selected, all system framebuffers are always
marked as fallback platform framebuffers as usual.
Note: Legacy fbdev drivers, including vesafb, efifb, uvesafb, will
not be able to pick up generic system framebuffers if this option
is selected. You are highly encouraged to enable simplefb as
replacement if you select this option. simplefb can correctly deal
with generic system framebuffers. But you should still keep vesafb
and others enabled as fallback if a system framebuffer is
incompatible with simplefb.
If unsure, say Y.
config TH1520_AON_PROTOCOL
tristate "Always-On firmware protocol"
depends on ARCH_THEAD || COMPILE_TEST
depends on MAILBOX
help
Power, clock, and resource management capabilities on the TH1520 SoC are
managed by the E902 core. Firmware running on this core communicates with
the kernel through the Always-On protocol, using hardware mailbox as a medium.
Say yes if you need such capabilities.
config TI_SCI_PROTOCOL
tristate "TI System Control Interface (TISCI) Message Protocol"
depends on TI_MESSAGE_MANAGER
default ARCH_K3
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.
config TRUSTED_FOUNDATIONS
bool "Trusted Foundations secure monitor support"
depends on ARM && CPU_V7
help
Some devices (including most early Tegra-based consumer devices on
the market) are booted with the Trusted Foundations secure monitor
active, requiring some core operations to be performed by the secure
monitor instead of the kernel.
This option allows the kernel to invoke the secure monitor whenever
required on devices using Trusted Foundations. See the functions and
comments in linux/firmware/trusted_foundations.h or the device tree
bindings for "tlm,trusted-foundations" for details on how to use it.
Choose N if you don't know what this is about.
config TURRIS_MOX_RWTM
tristate "Turris Mox rWTM secure firmware driver"
depends on ARCH_MVEBU || COMPILE_TEST
depends on HAS_DMA && OF
depends on MAILBOX
select HW_RANDOM
select ARMADA_37XX_RWTM_MBOX
help
This driver communicates with the firmware on the Cortex-M3 secure
processor of the Turris Mox router. Enable if you are building for
Turris Mox, and you will be able to read the device serial number and
other manufacturing data and also utilize the Entropy Bit Generator
for hardware random number generation.
if TURRIS_MOX_RWTM
config TURRIS_MOX_RWTM_KEYCTL
bool "Turris Mox rWTM ECDSA message signing"
default y
depends on KEYS
depends on ASYMMETRIC_KEY_TYPE
select CZNIC_PLATFORMS
select TURRIS_SIGNING_KEY
help
Say Y here to add support for ECDSA message signing with board private
key (each Turris Mox has an ECDSA private key generated in the secure
coprocessor when manufactured). This functionality is exposed via the
keyctl() syscall.
