32 mainmenu "Libpayload Configuration"
34 menu "Generic Options"
37 bool "GPLv2-licensed Options"
41 Prompt for options that will build code licensed under the GNU General
42 Public License (version 2). This will subject the whole payload to the
43 terms of this license (including its provision to release all sources,
44 please see the LICENSE_GPL file for details).
47 bool "Experimental Options"
50 Prompt for experimental functionality. Attention: This is not likely
51 to work without problems
54 bool "Developer Options"
57 Prompt for developer options. These options are only interesting for
58 libpayload developers.
61 bool "ChromeOS Options"
64 Select configuration defaults appropriate for ChromeOS boards.
67 prompt "Compiler to use"
70 This option allows you to select the compiler.
75 Use the GNU Compiler Collection (GCC).
77 config COMPILER_LLVM_CLANG
85 bool "Use link time optimization (LTO)"
87 depends on COMPILER_GCC
89 Compile with link time optimization. This can often decrease the
90 final binary size, but may increase compilation time.
93 bool "Remote GDB stub"
97 Enable Remote GDB debugging support.
99 config MEMMAP_RAM_ONLY
100 bool "Only consider RAM entries in memory map for further processing"
105 menu "Architecture Options"
108 prompt "Target Architecture"
114 Support the ARM architecture
119 Support the x86_32 architecture
124 Support the x86_64 architecture
129 Support the ARM64 architecture
132 bool "Mock architecture (for unit tests)"
134 This enables the mock architecture (for unit tests) that is intended
135 to be used for testing purposes, to either test payloads or libpayload itself.
136 It provides necessary headers, but requires mocking (providing implementation
137 for) arch-specific functions.
143 default y if ARCH_X86_32 || ARCH_X86_64
145 Support the x86 architecture
148 bool "Multiboot header support"
150 default y if !CHROMEOS
156 This is the heap size (malloc'able size) available
159 If unsure, set to 131072 (128K)
165 This is the stack size available to the payload.
167 If unsure, set to 16384 (16K)
171 default 0x04000000 if ARCH_ARM
172 default 0x80100000 if ARCH_ARM64
173 default 0x00100000 if ARCH_X86
174 default 0x00000000 if ARCH_MOCK
176 This is the base address for the payload.
178 If unsure, set to 0x00100000 on x86,
179 0x04000000 on ARM or 0x80100000 on ARM64.
183 menu "Standard Libraries"
186 bool "Enable C library support"
190 bool "Build a curses library"
191 default y if !CHROMEOS
194 prompt "Curses implementation"
201 TinyCurses was the first curses implementation for libpayload.
202 It features low memory consumption, static allocation of larger
203 data structures (so few or no memory allocation calls) and a
209 libpayload's PDCurses port provides a full features curses
210 implementation, including libpanel, libmenu and libform (which
211 are taken from ncurses).
212 It requires more system resources, in particularily heap memory.
216 source "libcbfs/Kconfig"
222 LZMA decoder implementation, usable eg. by CBFS,
229 Decoder implementation for the LZ4 compression algorithm.
230 Adds standalone functions (CBFS support coming soon).
232 source "vboot/Kconfig"
236 menu "Console Options"
238 config SKIP_CONSOLE_INIT
239 bool "Skip initializing the consoles at startup"
240 default y if CHROMEOS
243 Normally, libpayload will initialize console input/output on startup
244 before the payload itself gets control. This option disables that
245 behavior and leaves console initialization up to the payload.
248 bool "Send output to the in memory CBMEM console"
251 config SERIAL_CONSOLE
252 bool "See output on the serial port console"
255 config 8250_SERIAL_CONSOLE

286 bool "PL011 compatible serial port driver"
287 depends on 8250_SERIAL_CONSOLE
291 ## This default is currently not used on non-x86 systems.
292 hex "Default I/O base for the serial port (default 0x3f8)"
293 depends on SERIAL_CONSOLE && ARCH_X86
296 config SERIAL_SET_SPEED
297 bool "Override the serial console baud rate"
299 depends on SERIAL_CONSOLE
301 config SERIAL_BAUD_RATE
302 int "Serial console baud rate (default 115200)"
303 depends on SERIAL_SET_SPEED
306 config SERIAL_ACS_FALLBACK
307 bool "Use plain ASCII characters for ACS"
309 depends on SERIAL_CONSOLE
311 The alternate character set (ACS) is used for drawing lines and
312 displaying a couple of other special graphics characters. The
313 ACS characters generally look good on screen, but can be difficult
314 to cut and paste from a terminal window to a text editor.
316 Say 'y' here if you want to always use plain ASCII characters to
317 approximate the appearance of ACS characters on the serial port
321 bool "See output on a video console"
324 config VGA_VIDEO_CONSOLE
325 bool "VGA video console driver"
326 depends on ARCH_X86 && VIDEO_CONSOLE
327 default y if !CHROMEOS
329 config GEODELX_VIDEO_CONSOLE
330 bool "Geode LX video console driver"
331 depends on ARCH_X86 && VIDEO_CONSOLE
334 config COREBOOT_VIDEO_CONSOLE
335 bool "coreboot video console driver"
336 depends on VIDEO_CONSOLE && !GEODELX_VIDEO_CONSOLE
337 default y if CHROMEOS
340 Say Y here if coreboot switched to a graphics mode and
341 your payload wants to use it.
343 config COREBOOT_VIDEO_CENTERED
344 bool "Center a classic 80x25 console on bigger screens"
345 depends on COREBOOT_VIDEO_CONSOLE
347 Say 'y' here if your payload is hardcoded to a 80x25 console. Otherwise
348 its output would look squeezed into the upper-left corner of the screen.
350 config FONT_SCALE_FACTOR
351 int "Scale factor for the included font"
352 depends on GEODELX_VIDEO_CONSOLE || COREBOOT_VIDEO_CONSOLE
355 By default (value of 0), the scale factor is automatically
356 calculated to ensure at least 130 columns (when possible).
358 config CBGFX_FAST_RESAMPLE
359 bool "CBGFX: use faster (less pretty) image scaling"
362 When payloads use the CBGFX library to draw .BMPs on the screen,
363 they will be resampled with an anti-aliasing filter to scale to the
364 requested output size. The default implementation should normally be
365 fast enough, but if desired this option can make it about 50-100%
366 faster at the cost of quality. (It changes the 'a' parameter in the
367 Lanczos resampling algorithm from 3 to 2.)
369 Only affects .BMPs that aren't already provided at the right size.
372 bool "A common PC i8042 driver"
373 default y if PC_KEYBOARD || PC_MOUSE
376 To be used by PC_KEYBOARD and PC_MOUSE.
379 bool "Allow input from a PC mouse"
380 default n if CHROMEOS
381 default y if ARCH_X86 # uses IO
384 PS/2 mouse driver on top of PC_I8042.
387 bool "Allow input from a PC keyboard"
388 default y if ARCH_X86 # uses IO
391 config PC_KEYBOARD_LAYOUT_US
392 bool "English (US) keyboard layout"
393 depends on PC_KEYBOARD
396 config PC_KEYBOARD_LAYOUT_DE
397 bool "German keyboard layout"
398 depends on PC_KEYBOARD
401 config PC_KEYBOARD_TRANSLATION
402 bool "Enable or Disable translation in PC keyboard set 2 on exit"
403 depends on PC_KEYBOARD
411 bool "Support for PCI devices"
412 default y if ARCH_X86
416 bool "Support for PCI devices with port IO"
417 depends on PCI && IO_ADDRESS_SPACE
418 default y if ARCH_X86
422 bool "Support for PCIe devices on MediaTek platforms"
423 depends on PCI && !PCI_IO_OPS
427 bool "Support for PCIe devices on Qualcomm platforms"
428 depends on PCI && !PCI_IO_OPS
432 bool "Support for reading/writing NVRAM bytes"
433 depends on ARCH_X86 # for now
437 bool "Support for mouse cursor handling"
438 default y if PC_MOUSE
441 Provides a common interface for various mouse cursor drivers.
442 * Supports up to 32 buttons.
443 * Supports 3 axis mice.
444 * Applies simple cursor acceleration.
445 * Allows to set cursor acceleration and cursor speed.
447 config RTC_PORT_EXTENDED_VIA
448 bool "Extended RTC ports are 0x74/0x75"
451 For recent chipsets with 256 NVRAM bytes, you have to access the
452 upper 128 bytes (128-255) using two different I/O ports,
455 On some chipsets this can be a different set of ports, though.
456 The VIA VT8237R for example only recognizes the ports 0x74/0x75
457 for accessing the high 128 NVRAM bytes (as seems to be the case for
458 multiple VIA chipsets).
460 If you want to read or write CMOS bytes on computers with one of
461 these chipsets, say 'y' here.
464 bool "Support for PC speaker"
466 default y if !CHROMEOS
468 source "drivers/timer/Kconfig"
469 source "drivers/storage/Kconfig"
470 source "drivers/usb/Kconfig"
478 bool "Debug memory allocator"
481 Select this option if you want to debug the memory allocator. This
482 option logs all uses of the following functions:
484 void free(void *ptr);
485 void *malloc(size_t size);
486 void *calloc(size_t nmemb, size_t size);
487 void *realloc(void *ptr, size_t size);
488 void *memalign(size_t align, size_t size);
490 Say N here unless you are debugging memory allocator problems.
502 config IO_ADDRESS_SPACE
506 This option is turned on if the target system has a separate
507 IO address space. This is typically only the case on x86.
