-# 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.
-
- In addition, you need to pass user_debug=N on the kernel command
- line to enable this feature. N consists of the sum of:
-
- 1 - undefined instruction events
- 2 - system calls
- 4 - invalid data aborts
- 8 - SIGSEGV faults
- 16 - SIGBUS faults
-
-config DEBUG_INFO
- bool "Include GDB debugging information in kernel binary"
- help
- Say Y here to include source-level debugging information in the
- `vmlinux' binary image. This is handy if you want to use gdb or
- addr2line to debug the kernel. It has no impact on the in-memory
- footprint of the running kernel but it can increase the amount of
- time and disk space needed for compilation of the kernel. If in
- doubt say N.
-
-config DEBUG_KERNEL
- bool "Kernel debugging"
- help
- Say Y here if you are developing drivers or trying to debug and
- identify kernel problems.
-
-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_WAITQ
- bool "Wait queue debugging"
- depends on DEBUG_KERNEL
-
-config DEBUG_BUGVERBOSE
- bool "Verbose BUG() reporting (adds 70K)"
- depends on DEBUG_KERNEL
- help
- Say Y here to make BUG() panics output the file name and line number
- of the BUG call as well as the EIP and oops trace. This aids
- debugging but costs about 70-100K of memory.
-
-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.
-
-config DEBUG_ICEDCC
- bool "Kernel low-level debugging via EmbeddedICE DCC channel"
- depends on DEBUG_LL
- help
- Say Y here if you want the debug print routines to direct their
- output to the EmbeddedICE macrocell's DCC channel using
- co-processor 14. This is known to work on the ARM9 style ICE
- channel.
-
- It does include a timeout to ensure that the system does not
- totally freeze when there is nothing connected to read.
-
-config DEBUG_DC21285_PORT
- bool "Kernel low-level debugging messages via footbridge serial port"
- depends on DEBUG_LL && FOOTBRIDGE
- help
- Say Y here if you want the debug print routines to direct their
- output to the serial port in the DC21285 (Footbridge). Saying N
- will cause the debug messages to appear on the first 16550
- serial port.
-
-config DEBUG_CLPS711X_UART2
- bool "Kernel low-level debugging messages via UART2"
- depends on DEBUG_LL && ARCH_CLPS711X
- help
- Say Y here if you want the debug print routines to direct their
- output to the second serial port on these devices. Saying N will
- cause the debug messages to appear on the first serial port.
-
-config DEBUG_S3C2410_PORT
- depends on DEBUG_LL && ARCH_S3C2410
- bool "Kernel low-level debugging messages via S3C2410 UART"
- help
- Say Y here if you want debug print routines to go to one of the
- S3C2410 internal UARTs. The chosen UART must have been configured
- before it is used.
-
-config DEBUG_S3C2410_UART
- int
- depends on DEBUG_LL && ARCH_S3C2410
- default "0"
- help
- Choice for UART for kernel low-level using S3C2410 UARTS,
- should be between zero and two. The port must have been
- initalised by the boot-loader before use.
