| 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_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.) |
| |

| 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 |

| 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. |

| 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 QCOM_SCM |
| tristate |
| |
| 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 SYSFB |
| bool |
| default y |
| depends on X86 || EFI |
| |
| config SYSFB_SIMPLEFB |
| bool "Mark VGA/VBE/EFI FB as generic system framebuffer" |
| depends on 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 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. |
| |
| 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. |
