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.
