This is used by some boot loaders (e.g., GRUB) when loading Zephyr. It is safe to leave this option on if you're not sure. It only expands the text segment by 12-16 bytes and is typically ignored if not needed. config X86_MULTIBOOT_INFO bool "Preserve multiboot information structure" depends on X86_MULTIBOOT default n help Multiboot passes a pointer to an information structure to the kernel entry point. Some drivers (e.g., the multiboot framebuffer display driver) need to refer to information in this structure, and so set this option to preserve the data in a permanent location. if X86_MULTIBOOT config X86_MULTIBOOT_FRAMEBUF bool "Multiboot framebuffer support" default n select DISPLAY select FRAMEBUF_DISPLAY select X86_MULTIBOOT_INFO if X86_MULTIBOOT_FRAMEBUF config X86_MULTIBOOT_FRAMEBUF_X int "Multiboot framebuffer X pixels" default 640 config X86_MULTIBOOT_FRAMEBUF_Y int "Multiboot framebuffer Y pixels" default 480 endif # X86_MULTIBOOT_FRAMEBUF endif # X86_MULTIBOOT source "arch/x86/core/Kconfig.ia32" source "arch/x86/core/Kconfig.x64" endmenu
