-config DEBUG_KERNEL
- bool "Kernel debugging"
- help
- Say Y here if you are developing drivers or trying to debug and
- identify kernel problems.
-
-config EARLY_PRINTK
- bool "Early printk"
- depends on EMBEDDED && DEBUG_KERNEL
- default n
- help
- Write kernel log output directly into the VGA buffer or to a serial
- port.
-
- 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 or the X server. 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
-
-config DEBUG_SLAB
- bool "Debug memory allocations"
- depends on DEBUG_KERNEL
- help
- Say Y here to have the kernel do limited verification on memory
- allocation as well as poisoning memory on free to catch use of freed
- memory.
-
-config MAGIC_SYSRQ
- bool "Magic SysRq key"
- depends on DEBUG_KERNEL
- help
- If you say Y here, you will have some control over the system even
- if the system crashes for example during kernel debugging (e.g., you
- will be able to flush the buffer cache to disk, reboot the system
- immediately or dump some status information). This is accomplished
- by pressing various keys while holding SysRq (Alt+PrintScreen). It
- also works on a serial console (on PC hardware at least), if you
- send a BREAK and then within 5 seconds a command keypress. The
- keys are documented in <file:Documentation/sysrq.txt>. Don't say Y
- unless you really know what this hack does.
-
-config DEBUG_SPINLOCK
- bool "Spinlock debugging"
- depends on DEBUG_KERNEL
- help
- Say Y here and build SMP to catch missing spinlock initialization
- and certain other kinds of spinlock errors commonly made. This is
- best used in conjunction with the NMI watchdog so that spinlock
- deadlocks are also debuggable.
-
-config DEBUG_SPINLOCK_SLEEP
- bool "Sleep-inside-spinlock checking"
- depends on DEBUG_KERNEL
- help
- If you say Y here, various routines which may sleep will become very
- noisy if they are called with a spinlock held.
-
-config DEBUG_PAGEALLOC
- bool "Page alloc debugging"
- depends on DEBUG_KERNEL
- help
- Unmap pages from the kernel linear mapping after free_pages().
- This results in a large slowdown, but helps to find certain types
- of memory corruptions.
-
-config DEBUG_HIGHMEM
- bool "Highmem debugging"
- depends on DEBUG_KERNEL && HIGHMEM
- help
- This options enables addition error checking for high memory systems.
- Disable for production systems.
-
-config DEBUG_INFO
- bool "Compile the kernel with debug info"
- depends on DEBUG_KERNEL
- help
- If you say Y here the resulting kernel image will include
- debugging info resulting in a larger kernel image.
- Say Y here only if you plan to use gdb to debug the kernel.
- If you don't debug the kernel, you can say N.
-
-config DEBUG_BUGVERBOSE
- bool "Verbose BUG() reporting"
- depends on DEBUG_KERNEL
-
-config FRAME_POINTER
- bool "Compile the kernel with frame pointers"
- depends on DEBUG_KERNEL
- help
- If you say Y here the resulting kernel image will be slightly larger
- and slower, but it will give very useful debugging information.
- If you don't debug the kernel, you can say N, but we may not be able
- to solve problems without frame pointers.
-
-config GDBSTUB
- bool "Remote GDB kernel debugging"
- depends on DEBUG_KERNEL
- select DEBUG_INFO
- select FRAME_POINTER
- help
- If you say Y here, it will be possible to remotely debug the kernel
- using gdb. This enlarges your kernel ELF image disk size by several
- megabytes and requires a machine with more than 16 MB, better 32 MB
- RAM to avoid excessive linking time. This is only useful for kernel
- hackers. If unsure, say N.

-config GDBSTUB_IMMEDIATE
- bool "Break into GDB stub immediately"
- depends on GDBSTUB
- help
- If you say Y here, GDB stub will break into the program as soon as
- possible, leaving the program counter at the beginning of
- start_kernel() in init/main.c.
-
-config GDB_CONSOLE
- bool "Console output to GDB"
- depends on KGDB
- help
- If you are using GDB for remote debugging over a serial port and
- would like kernel messages to be formatted into GDB $O packets so
- that GDB prints them as program output, say 'Y'.
