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)"
88 Compile with link time optimization. This can often decrease the
89 final binary size, but may increase compilation time.
92 bool "Remote GDB stub"
96 Enable Remote GDB debugging support.
98 config MEMMAP_RAM_ONLY
99 bool "Only consider RAM entries in memory map for further processing"
104 menu "Architecture Options"
107 prompt "Target Architecture"
113 Support the ARM architecture
118 Support the x86_32 architecture
123 Support the x86_64 architecture
128 Support the ARM64 architecture
131 bool "Mock architecture (for unit tests)"
133 This enables the mock architecture (for unit tests) that is intended
134 to be used for testing purposes, to either test payloads or libpayload itself.
135 It provides necessary headers, but requires mocking (providing implementation
136 for) arch-specific functions.
142 default y if ARCH_X86_32 || ARCH_X86_64
144 Support the x86 architecture
147 bool "Multiboot header support"
149 default y if !CHROMEOS
155 This is the heap size (malloc'able size) available
158 If unsure, set to 131072 (128K)
164 This is the stack size available to the payload.
166 If unsure, set to 16384 (16K)
170 default 0x04000000 if ARCH_ARM
171 default 0x80100000 if ARCH_ARM64
172 default 0x00100000 if ARCH_X86
173 default 0x00000000 if ARCH_MOCK
175 This is the base address for the payload.
177 If unsure, set to 0x00100000 on x86,
178 0x04000000 on ARM or 0x80100000 on ARM64.
182 menu "Standard Libraries"
185 bool "Enable C library support"
189 bool "Build a curses library"
190 default y if !CHROMEOS
193 prompt "Curses implementation"
200 TinyCurses was the first curses implementation for libpayload.
201 It features low memory consumption, static allocation of larger
202 data structures (so few or no memory allocation calls) and a
208 libpayload's PDCurses port provides a full features curses
209 implementation, including libpanel, libmenu and libform (which
210 are taken from ncurses).
211 It requires more system resources, in particularily heap memory.
215 source "libcbfs/Kconfig"
221 LZMA decoder implementation, usable eg. by CBFS,
228 Decoder implementation for the LZ4 compression algorithm.
229 Adds standalone functions (CBFS support coming soon).
231 source "vboot/Kconfig"
235 menu "Console Options"
237 config SKIP_CONSOLE_INIT
238 bool "Skip initializing the consoles at startup"
239 default y if CHROMEOS
242 Normally, libpayload will initialize console input/output on startup
243 before the payload itself gets control. This option disables that
244 behavior and leaves console initialization up to the payload.
247 bool "Send output to the in memory CBMEM console"
250 config SERIAL_CONSOLE
251 bool "See output on the serial port console"
254 config 8250_SERIAL_CONSOLE

286 depends on 8250_SERIAL_CONSOLE
290 ## This default is currently not used on non-x86 systems.
291 hex "Default I/O base for the serial port (default 0x3f8)"
292 depends on SERIAL_CONSOLE && ARCH_X86
295 config SERIAL_SET_SPEED
296 bool "Override the serial console baud rate"
298 depends on SERIAL_CONSOLE
300 config SERIAL_BAUD_RATE
301 int "Serial console baud rate (default 115200)"
302 depends on SERIAL_SET_SPEED
305 config SERIAL_ACS_FALLBACK
306 bool "Use plain ASCII characters for ACS"
308 depends on SERIAL_CONSOLE
310 The alternate character set (ACS) is used for drawing lines and
311 displaying a couple of other special graphics characters. The
312 ACS characters generally look good on screen, but can be difficult
313 to cut and paste from a terminal window to a text editor.
315 Say 'y' here if you want to always use plain ASCII characters to
316 approximate the appearance of ACS characters on the serial port
320 bool "See output on a video console"
323 config VGA_VIDEO_CONSOLE
324 bool "VGA video console driver"
325 depends on ARCH_X86 && VIDEO_CONSOLE
326 default y if !CHROMEOS
328 config GEODELX_VIDEO_CONSOLE
329 bool "Geode LX video console driver"
330 depends on ARCH_X86 && VIDEO_CONSOLE
333 config COREBOOT_VIDEO_CONSOLE
334 bool "coreboot video console driver"
335 depends on VIDEO_CONSOLE && !GEODELX_VIDEO_CONSOLE
336 default y if CHROMEOS
339 Say Y here if coreboot switched to a graphics mode and
340 your payload wants to use it.
342 config COREBOOT_VIDEO_CENTERED
343 bool "Center a classic 80x25 console on bigger screens"
344 depends on COREBOOT_VIDEO_CONSOLE
346 Say 'y' here if your payload is hardcoded to a 80x25 console. Otherwise
347 its output would look squeezed into the upper-left corner of the screen.
349 config FONT_SCALE_FACTOR
350 int "Scale factor for the included font"
351 depends on GEODELX_VIDEO_CONSOLE || COREBOOT_VIDEO_CONSOLE
354 By default (value of 0), the scale factor is automatically
355 calculated to ensure at least 130 columns (when possible).
357 config CBGFX_FAST_RESAMPLE
358 bool "CBGFX: use faster (less pretty) image scaling"
361 When payloads use the CBGFX library to draw .BMPs on the screen,
362 they will be resampled with an anti-aliasing filter to scale to the
363 requested output size. The default implementation should normally be
364 fast enough, but if desired this option can make it about 50-100%
365 faster at the cost of quality. (It changes the 'a' parameter in the
366 Lanczos resampling algorithm from 3 to 2.)
368 Only affects .BMPs that aren't already provided at the right size.
371 bool "A common PC i8042 driver"
372 default y if PC_KEYBOARD || PC_MOUSE
375 To be used by PC_KEYBOARD and PC_MOUSE.
378 bool "Allow input from a PC mouse"
379 default n if CHROMEOS
380 default y if ARCH_X86 # uses IO
383 PS/2 mouse driver on top of PC_I8042.

395 config PC_KEYBOARD_LAYOUT_DE
396 bool "German keyboard layout"
397 depends on PC_KEYBOARD
400 config PC_KEYBOARD_TRANSLATION
401 bool "Enable or Disable translation in PC keyboard set 2 on exit"
402 depends on PC_KEYBOARD
410 bool "Support for PCI devices"
411 default y if ARCH_X86
415 bool "Support for PCI devices with port IO"
416 depends on PCI && IO_ADDRESS_SPACE
417 default y if ARCH_X86
421 bool "Support for PCIe devices on MediaTek platforms"
422 depends on PCI && !PCI_IO_OPS
426 bool "Support for PCIe devices on Qualcomm platforms"
427 depends on PCI && !PCI_IO_OPS
431 bool "Support for reading/writing NVRAM bytes"
432 depends on ARCH_X86 # for now
436 bool "Support for mouse cursor handling"
437 default y if PC_MOUSE
440 Provides a common interface for various mouse cursor drivers.
441 * Supports up to 32 buttons.
442 * Supports 3 axis mice.
443 * Applies simple cursor acceleration.
444 * Allows to set cursor acceleration and cursor speed.
446 config RTC_PORT_EXTENDED_VIA
447 bool "Extended RTC ports are 0x74/0x75"
450 For recent chipsets with 256 NVRAM bytes, you have to access the
451 upper 128 bytes (128-255) using two different I/O ports,
454 On some chipsets this can be a different set of ports, though.
455 The VIA VT8237R for example only recognizes the ports 0x74/0x75
456 for accessing the high 128 NVRAM bytes (as seems to be the case for
457 multiple VIA chipsets).
459 If you want to read or write CMOS bytes on computers with one of
460 these chipsets, say 'y' here.
463 bool "Support for PC speaker"
465 default y if !CHROMEOS
467 source "drivers/timer/Kconfig"
468 source "drivers/storage/Kconfig"
469 source "drivers/usb/Kconfig"
477 bool "Debug memory allocator"
480 Select this option if you want to debug the memory allocator. This
481 option logs all uses of the following functions:
483 void free(void *ptr);
484 void *malloc(size_t size);
485 void *calloc(size_t nmemb, size_t size);
486 void *realloc(void *ptr, size_t size);
487 void *memalign(size_t align, size_t size);
489 Say N here unless you are debugging memory allocator problems.
501 config IO_ADDRESS_SPACE
505 This option is turned on if the target system has a separate
506 IO address space. This is typically only the case on x86.
