menu "Kernel hacking" source "lib/Kconfig.debug" # RMK wants arm kernels compiled with frame pointers so hardwire this to y. # If you know what you are doing and are willing to live without stack # traces, you can get a slightly smaller kernel by setting this option to # n, but then RMK will have to kill you ;). config FRAME_POINTER bool default y help If you say N here, the resulting kernel will be slightly smaller and faster. However, when a problem occurs with the kernel, the information that is reported is severely limited. Most people should say Y here. config DEBUG_USER bool "Verbose user fault messages" help When a user program crashes due to an exception, the kernel can print a brief message explaining what the problem was. This is sometimes helpful for debugging but serves no purpose on a production system. Most people should say N here. config DEBUG_WAITQ bool "Wait queue debugging" depends on DEBUG_KERNEL config DEBUG_ERRORS bool "Verbose kernel error messages" depends on DEBUG_KERNEL help This option controls verbose debugging information which can be printed when the kernel detects an internal error. This debugging information is useful to kernel hackers when tracking down problems, but mostly meaningless to other people. It's safe to say Y unless you are concerned with the code size or don't want to see these messages. # These options are only for real kernel hackers who want to get their hands dirty. config DEBUG_LL bool "Kernel low-level debugging functions" depends on DEBUG_KERNEL help Say Y here to include definitions of printascii, printchar, printhex in the kernel. This is helpful if you are debugging code that executes before the console is initialized. endmenu
