This will subject the whole payload to the terms of this license (including its provision to release all sources, please see the LICENSE_GPL file for details). config EXPERIMENTAL bool "Experimental Options" default n help Prompt for experimental functionality. Attention: This is not likely to work without problems config DEVELOPER bool "Developer Options" default n help Prompt for developer options. These options are only interesting for libpayload developers. config CHROMEOS bool "Chrome OS Options" default n help Select configuration defaults appropriate for Chrome OS boards. choice prompt "Compiler to use" default COMPILER_GCC help This option allows you to select the compiler. config COMPILER_GCC bool "GCC" help Use the GNU Compiler Collection (GCC). config COMPILER_LLVM_CLANG bool "LLVM/clang" help Use LLVM/clang. endchoice config LTO bool "Use link time optimization (LTO)" default n depends on COMPILER_GCC help Compile with link time optimization. This can often decrease the final binary size, but may increase compilation time. config REMOTEGDB bool "Remote GDB stub" default n depends on GPL help Enable Remote GDB debugging support. config MEMMAP_RAM_ONLY bool "Only consider RAM entries in memory map for further processing" default n endmenu menu "Architecture Options" choice prompt "Target Architecture" default ARCH_X86 config ARCH_ARM bool "ARM" help Support the ARM architecture config ARCH_X86 bool "x86" help Support the x86 architecture config ARCH_ARM64 bool "ARM64" help Support the ARM64 architecture config ARCH_MOCK bool "Mock architecture (for unit tests)" help This enables the mock architecture (for unit tests) that is intended to be used for testing purposes, to either test payloads or libpayload itself. It provides necessary headers, but requires mocking (providing implementation for) arch-specific functions. endchoice config MULTIBOOT bool "Multiboot header support" depends on ARCH_X86 default y if !CHROMEOS config HEAP_SIZE int "Heap size" default 131072 help This is the heap size (malloc'able size) available to the payload. If unsure, set to 131072 (128K) config STACK_SIZE int "Stack size" default 16384 help This is the stack size available to the payload. If unsure, set to 16384 (16K) config BASE_ADDRESS hex "Base address" default 0x04000000 if ARCH_ARM default 0x80100000 if ARCH_ARM64 default 0x00100000 if ARCH_X86 default 0x00000000 if ARCH_MOCK help This is the base address for the payload. If unsure, set to 0x00100000 on x86, 0x04000000 on ARM or 0x80100000 on ARM64. endmenu config USE_MARCH_586 bool "Use march=586 qualifier to build" default n depends on ARCH_X86 help Allow a platform or processor to select to be compiled using the '-march=i586' option instead of the typical '-march=i686' menu "Standard Libraries" config LIBC bool "Enable C library support" default y config CURSES bool "Build a curses library" default y if !CHROMEOS 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 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. config LZ4 bool "LZ4 decoder" default y help Decoder implementation for the LZ4 compression algorithm. Adds standalone functions (CBFS support coming soon). source "vboot/Kconfig" endmenu menu "Console Options" config SKIP_CONSOLE_INIT bool "Skip initializing the consoles at startup" default y if CHROMEOS 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 8250_SERIAL_CONSOLE bool "8250-compatible serial port driver (including IO and MMIO)" depends on SERIAL_CONSOLE default y if ARCH_X86 config S5P_SERIAL_CONSOLE bool "Exynos SOC, S5P compatible serial port driver" depends on SERIAL_CONSOLE default n config IPQ806X_SERIAL_CONSOLE bool "IPQ806x SOC compatible serial port driver" depends on SERIAL_CONSOLE default n config IPQ40XX_SERIAL_CONSOLE bool "IPQ40xx SOC compatible serial port driver" depends on SERIAL_CONSOLE default n config QCS405_SERIAL_CONSOLE bool "QCS405 SOC compatible serial port driver" depends on SERIAL_CONSOLE default n config QUALCOMM_QUPV3_SERIAL_CONSOLE bool "Qualcomm QUPV3 serial port driver" depends on SERIAL_CONSOLE default n config PL011_SERIAL_CONSOLE bool "PL011 compatible serial port driver" depends on 8250_SERIAL_CONSOLE default n config SERIAL_IOBASE ## This default is currently not used on non-x86 systems. hex "Default I/O base for the serial port (default 0x3f8)" depends on SERIAL_CONSOLE && ARCH_X86 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 if !CHROMEOS 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 y if CHROMEOS default n help Say Y here if coreboot switched to a graphics mode and your payload wants to use it. config COREBOOT_VIDEO_CENTERED bool "Center a classic 80x25 console on bigger screens" depends on COREBOOT_VIDEO_CONSOLE help Say 'y' here if your payload is hardcoded to a 80x25 console. Otherwise its output would look squeezed into the upper-left corner of the screen. config FONT_SCALE_FACTOR int "Scale factor for the included font" depends on GEODELX_VIDEO_CONSOLE || COREBOOT_VIDEO_CONSOLE default 0 help By default (value of 0), the scale factor is automatically calculated to ensure at least 130 columns (when possible). config CBGFX_FAST_RESAMPLE bool "CBGFX: use faster (less pretty) image scaling" default n help When payloads use the CBGFX library to draw .BMPs on the screen, they will be resampled with an anti-aliasing filter to scale to the requested output size. The default implementation should normally be fast enough, but if desired this option can make it about 50-100% faster at the cost of quality. (It changes the 'a' parameter in the Lanczos resampling algorithm from 3 to 2.) Only affects .BMPs that aren't already provided at the right size. config PC_I8042 bool "A common PC i8042 driver" default y if PC_KEYBOARD || PC_MOUSE default n help To be used by PC_KEYBOARD and PC_MOUSE. config PC_MOUSE bool "Allow input from a PC mouse" default n if CHROMEOS default y if ARCH_X86 # uses IO default n help PS/2 mouse driver on top of PC_I8042. config PC_KEYBOARD bool "Allow input from a PC keyboard" default y if ARCH_X86 # uses IO default n 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 config PC_KEYBOARD_TRANSLATION bool "Enable or Disable translation in PC keyboard set 2 on exit" depends on PC_KEYBOARD default y 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 MOUSE_CURSOR bool "Support for mouse cursor handling" default y if PC_MOUSE default n help Provides a common interface for various mouse cursor drivers. * Supports up to 32 buttons. * Supports 3 axis mice. * Applies simple cursor acceleration. * Allows to set cursor acceleration and cursor speed. 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 if !CHROMEOS source "drivers/timer/Kconfig" source "drivers/storage/Kconfig" source "drivers/usb/Kconfig" endmenu menu "Debugging" depends on DEVELOPER config DEBUG_MALLOC bool "Debug memory allocator" 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 config IO_ADDRESS_SPACE default n bool help This option is turned on if the target system has a separate IO address space.
