menu "Kernel hacking"
source "lib/Kconfig.debug"
config FRAME_POINTER
bool
default y
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.
config DEBUG_STACK_USAGE
bool "Enable stack utilization instrumentation"
depends on DEBUG_KERNEL
help
Enables the display of the minimum amount of free stack which each
task has ever had available in the sysrq-T output.
config EARLY_PRINTK
bool "Early printk support"
default y
help
Say Y here if you want to have an early console using the
earlyprintk=<name>[,<addr>][,<options>] kernel parameter. It
is assumed that the early console device has been initialised
by the boot loader prior to starting the Linux kernel.
config PID_IN_CONTEXTIDR
bool "Write the current PID to the CONTEXTIDR register"
help
Enabling this option causes the kernel to write the current PID to
the CONTEXTIDR register, at the expense of some additional
instructions during context switch. Say Y here only if you are
planning to use hardware trace tools with this kernel.
