Attention: This is not likely to work without problems config OBSOLETE bool "Obsolete Options" default n help Prompt for obsolete options. These options are for old, unsupported features and are likely to go away in the future. config DEVELOPER bool "Developer Options" default n help Prompt for developer options. These options are only interesting for libpayload developers. config CHROMEOS bool "ChromeOS specific features" default n help Enable ChromeOS specific features. endmenu menu "Architecture Options" choice prompt "Target Architecture" default ARCH_X86 config ARCH_ARMV7 bool "ARMv7" help Support the x86 architecture config ARCH_X86 bool "x86" help Support the x86 architecture endchoice config MEMMAP_RAM_ONLY bool "Only consider RAM entries in memory map for further processing" default n config MULTIBOOT bool "Multiboot header support" depends on ARCH_X86 default y endmenu menu "Standard Libraries" config LIBC bool "Enable C library support" default y config CURSES bool "Build a curses library" default y choice prompt "Curses implementation" default PDCURSES depends on CURSES config TINYCURSES bool "Tinycurses" help Tinycurses was the first curses implementation for libpayload. It features low memory consumption, static allocation of larger data structures (so few or no memory allocation calls) and a reduced feature set. config PDCURSES bool "PDCurses" help libpayload's PDCurses port provides a full features curses implementation, including libpanel, libmenu and libform (which are taken from ncurses). It requires more system resources, in particularily heap memory. endchoice config LAR bool "LAR support" default n depends on OBSOLETE help LAR is the archive format of (obsolete) coreboot v3 config CBFS bool "CBFS support" default y help CBFS is the archive format of coreboot config LZMA bool "LZMA decoder" default y help LZMA decoder implementation, usable eg. by CBFS, but also externally. endmenu menu "Console Options" config SKIP_CONSOLE_INIT bool "Skip initializing the consoles at startup" default n help Normally, libpayload will initialize console input/output on startup before the payload itself gets control. This option disables that behavior and leaves console initialization up to the payload. config CBMEM_CONSOLE bool "Send output to the in memory CBMEM console" default y config SERIAL_CONSOLE bool "See output on the serial port console" default y config X86_SERIAL_CONSOLE bool depends on ARCH_X86 && SERIAL_CONSOLE default y config SERIAL_IOBASE hex "I/O base for the serial port (default 0x3f8)" depends on X86_SERIAL_CONSOLE default 0x3f8 config SERIAL_SET_SPEED bool "Override the serial console baud rate" default n depends on SERIAL_CONSOLE config SERIAL_BAUD_RATE int "Serial console baud rate (default 115200)" depends on SERIAL_SET_SPEED default 115200 config SERIAL_ACS_FALLBACK bool "Use plain ASCII characters for ACS" default n depends on SERIAL_CONSOLE help The alternate character set (ACS) is used for drawing lines and displaying a couple of other special graphics characters. The ACS characters generally look good on screen, but can be difficult to cut and paste from a terminal window to a text editor. Say 'y' here if you want to always use plain ASCII characters to approximate the appearance of ACS characters on the serial port console. config VIDEO_CONSOLE bool "See output on a video console" default y config VGA_VIDEO_CONSOLE bool "VGA video console driver" depends on ARCH_X86 && VIDEO_CONSOLE default y config GEODELX_VIDEO_CONSOLE bool "Geode LX video console driver" depends on ARCH_X86 && VIDEO_CONSOLE default n config COREBOOT_VIDEO_CONSOLE bool "coreboot video console driver" depends on VIDEO_CONSOLE && !GEODELX_VIDEO_CONSOLE default n help Say Y here if coreboot switched to a graphics mode and your payload wants to use it. config PC_KEYBOARD bool "Allow input from a PC keyboard" default y config PC_KEYBOARD_LAYOUT_US bool "English (US) keyboard layout" depends on PC_KEYBOARD default y config PC_KEYBOARD_LAYOUT_DE bool "German keyboard layout" depends on PC_KEYBOARD default n endmenu menu "Drivers" config PCI bool "Support for PCI devices" depends on ARCH_X86 # for now default y config NVRAM bool "Support for reading/writing NVRAM bytes" depends on ARCH_X86 # for now default y config RTC_PORT_EXTENDED_VIA bool "Extended RTC ports are 0x74/0x75" default n help For recent chipsets with 256 NVRAM bytes, you have to access the upper 128 bytes (128-255) using two different I/O ports, usually 0x72/0x73. On some chipsets this can be a different set of ports, though. The VIA VT8237R for example only recognizes the ports 0x74/0x75 for accessing the high 128 NVRAM bytes (as seems to be the case for multiple VIA chipsets). If you want to read or write CMOS bytes on computers with one of these chipsets, say 'y' here. config SPEAKER bool "Support for PC speaker" depends on ARCH_X86 default y config STORAGE bool "Support for storage devices" default y help Select this option if you want support for storage devices (like hard drives, memory sticks or optical drives). config STORAGE_64BIT_LBA bool "Use 64-bit integers to address sectors" depends on STORAGE default n help If this is selected, sectors will be addressed by an 64-bit integer. Select this to support LBA-48 for ATA drives. config STORAGE_ATA bool "Support ATA drives (i.e. hard drives)" depends on STORAGE default y help Select this option if you want support for ATA storage devices (i.e. hard drives). config STORAGE_ATAPI bool "Support ATAPI drives (i.e. optical drives)" depends on STORAGE default y select STORAGE_ATA help Select this option if you want support for ATAPI storage devices (i.e. optical drives like CD or DVD drives). config STORAGE_AHCI bool "Support for AHCI host controllers" depends on STORAGE && (STORAGE_ATA || STORAGE_ATAPI) && PCI default y help Select this option if you want support for SATA controllers in AHCI mode. config STORAGE_AHCI_ONLY_TESTED bool "Only enable tested controllers" depends on STORAGE_AHCI default y help If this option is selected only AHCI controllers which are known to work will be used. config USB bool "USB Support" default n config USB_UHCI bool "Support for USB UHCI controllers" depends on USB && ARCH_X86 help Select this option if you are going to use USB 1.1 on an Intel based system. config USB_OHCI bool "Support for USB OHCI controllers" depends on USB help Select this option if you are going to use USB 1.1 on a non-Intel based system. config USB_EHCI bool "Support for USB EHCI controllers" depends on USB help Select this option if you want to use USB 2.0 config USB_XHCI bool "Support for USB xHCI controllers" depends on USB help Select this option if you want to use USB 3.0 NOTE: This option is not (fully) implemented yet config USB_HID bool "Support for USB keyboards" depends on USB default y help Select this option if you want to use devices complying to the USB HID (Human Interface Device) standard. Such devices are for example keyboards and mice. Currently only keyboards are supported. Say Y here unless you know exactly what you are doing. config USB_HUB bool "Support for USB hubs" depends on USB default y help Select this option if you want to compile in support for USB hubs. Say Y here unless you know exactly what you are doing. config USB_MSC bool "Support for USB storage" depends on USB default y help Select this option if you want to compile in support for USB mass storage devices (USB memory sticks, hard drives, CDROM/DVD drives) Say Y here unless you know exactly what you are doing. config USB_GEN_HUB bool default n if (!USB_HUB && !USB_XHCI) default y if (USB_HUB || USB_XHCI) config USB_PCI bool "Auto-scan PCI bus for USB host controllers" depends on USB default y if ARCH_X86 default n endmenu menu "Debugging" depends on DEVELOPER config DEBUG_MALLOC bool "Debug memory allocator" depends on USB default n help Select this option if you want to debug the memory allocator. This option logs all uses of the following functions: void free(void *ptr); void *malloc(size_t size); void *calloc(size_t nmemb, size_t size); void *realloc(void *ptr, size_t size); void *memalign(size_t align, size_t size); Say N here unless you are debugging memory allocator problems. endmenu config BIG_ENDIAN default n bool config LITTLE_ENDIAN default n bool # Whether the target system has an IO address space. config IO_ADDRESS_SPACE default n bool source "arch/Config.in"
