menu "Kernel hacking" source "lib/Kconfig.debug" config EARLY_PRINTK	bool "Early printk" if EXPERT && DEBUG_KERNEL	default y	help	  Write kernel log output directly via the hypervisor console. 	  This is useful for kernel debugging when your machine crashes very	  early before the console code is initialized. For normal operation	  it is not recommended because it looks ugly and doesn't cooperate	  with klogd/syslogd. You should normally N here,	  unless you want to debug such a crash. config DEBUG_STACKOVERFLOW	bool "Check for stack overflows"	depends on DEBUG_KERNEL	help	  This option will cause messages to be printed if free stack space	  drops below a certain limit. config DEBUG_EXTRA_FLAGS	string "Additional compiler arguments when building with '-g'"	depends on DEBUG_INFO	default ""	help	  Debug info can be large, and flags like	  `-femit-struct-debug-baseonly' can reduce the kernel file	  size and build time noticeably.  Such flags are often	  helpful if the main use of debug info is line number info. endmenu
