# SPDX-License-Identifier: Apache-2.0 config BOARD string help This option holds the name of the board and is used to locate the files related to the board in the source tree (under boards/). The Board is the first location where we search for a linker.ld file, if not found we look for the linker file in soc/// config BOARD_REVISION def_string "$BOARD_REVISION" help If the BOARD has a revision field set, this is the revision. Otherwise, it is the empty string. For example, if BOARD is "plank@foo", this option will be "foo". If BOARD is "plank", this option will be the empty string. config BOARD_DEPRECATED_RELEASE string help This hidden option is set in the board configuration and indicates the Zephyr release that the board configuration will be removed. When set, any build for that board will generate a clearly visible deprecation warning. config QEMU_TARGET bool help Mark all QEMU targets with this variable for checking whether we are running in an emulated environment. config NET_DRIVERS bool default y if QEMU_TARGET && NETWORKING help When building for a qemu target then NET_DRIVERS will be default enabled to allow for easy use of SLIP or PPP # Note: $BOARD_DIR might be a glob pattern choice prompt "Board Selection" source "$(BOARD_DIR)/Kconfig.board" endchoice # Parse shields references # Don't do it as a menuconfig, as shield selection is a CMake feature. # This loads custom shields Kconfig (from BOARD_ROOT) osource "$(KCONFIG_BINARY_DIR)/Kconfig.shield" # This loads Zephyr base shield defconfigs rsource "shields/*/Kconfig.shield" menu "Board Options" config QEMU_ICOUNT bool "QEMU icount mode" depends on QEMU_TARGET default y if !NETWORKING && !BT help Enable QEMU virtual instruction counter. The virtual cpu will execute one instruction every 2^N ns of virtual time. This will give deterministic execution times from the guest point of view. config QEMU_ICOUNT_SHIFT int "QEMU icount shift value" depends on QEMU_ICOUNT help The virtual CPU will execute one instruction every 2^N nanoseconds of virtual time, where N is the value provided here. config QEMU_ICOUNT_SLEEP bool "QEMU icount sleep mode enable" depends on QEMU_ICOUNT help When the virtual CPU is sleeping, the virtual time will advance at default speed unless this option is set. With this option set, the virtual time will jump to the next timer deadline instantly whenever the virtual CPU goes to sleep mode and will not advance if no timer is enabled. This behavior gives deterministic execution times from the guest point of view. config QEMU_IVSHMEM_PLAIN_MEM_SIZE int "QEMU ivshmem-plain shared memory size in mega-bytes" default 1 depends on QEMU_TARGET && IVSHMEM && !IVSHMEM_DOORBELL help This sets the size of the shared memory when using ivshmem-plain device in Qemu. Note that it's in mega-bytes, so 1 means 1M for Qemu etc.. config QEMU_UEFI_BOOT bool "QEMU uses UEFI to boot up" default n depends on BUILD_OUTPUT_EFI && QEMU_TARGET && X86_64 help This option indicates that QEMU will use UEFI bootable method to boot up. # There might not be any board options, hence the optional source osource "$(BOARD_DIR)/Kconfig" endmenu config BOARD_HAS_TIMING_FUNCTIONS bool help Should be selected if board provides custom method for retrieving timestamps and cycle count.
