+ bool "Built-in Kernel Debugger support"
+ depends on DEBUG_KERNEL
+ select KALLSYMS
+ select KALLSYMS_ALL
+ help
+ This option provides a built-in kernel debugger. The built-in
+ kernel debugger contains commands which allow memory to be examined,
+ instructions to be disassembled and breakpoints to be set. For details,
+ see Documentation/kdb/kdb.mm and the manual pages kdb_bt, kdb_ss, etc.
+ Kdb can also be used via the serial port. Set up the system to
+ have a serial console (see Documentation/serial-console.txt).
+ The key sequence <escape>KDB on the serial port will cause the
+ kernel debugger to be entered with input from the serial port and
+ output to the serial console. If unsure, say N.
+
+config KDB_MODULES
+ tristate "KDB modules"
+ depends on KDB
+ help
+ KDB can be extended by adding your own modules, in directory
+ kdb/modules. This option selects the way that these modules should
+ be compiled, as free standing modules (select M) or built into the
+ kernel (select Y). If unsure say M.
+
+config KDB_OFF
+ bool "KDB off by default"
+ depends on KDB
+ help
+ Normally kdb is activated by default, as long as CONFIG_KDB is set.
+ If you want to ship a kernel with kdb support but only have kdb
+ turned on when the user requests it then select this option. When
+ compiled with CONFIG_KDB_OFF, kdb ignores all events unless you boot
+ with kdb=on or you echo "1" > /proc/sys/kernel/kdb. This option also
+ works in reverse, if kdb is normally activated, you can boot with
+ kdb=off or echo "0" > /proc/sys/kernel/kdb to deactivate kdb. If
+ unsure, say N.
+
+config KDB_CONTINUE_CATASTROPHIC
+ int "KDB continues after catastrophic errors"
+ depends on KDB
+ default "0"
+ help
+ This integer controls the behaviour of kdb when the kernel gets a
+ catastrophic error, i.e. for a panic, oops, NMI or other watchdog
+ tripping. CONFIG_KDB_CONTINUE_CATASTROPHIC interacts with
+ /proc/sys/kernel/kdb and CONFIG_CRASH_DUMP (if your kernel has the
+ LKCD patch).
+ When KDB is active (/proc/sys/kernel/kdb == 1) and a catastrophic
+ error occurs, nothing extra happens until you type 'go'.
+ CONFIG_KDB_CONTINUE_CATASTROPHIC == 0 (default). The first time
+ you type 'go', kdb warns you. The second time you type 'go', KDB
+ tries to continue - no guarantees that the kernel is still usable.
+ CONFIG_KDB_CONTINUE_CATASTROPHIC == 1. KDB tries to continue - no
+ guarantees that the kernel is still usable.
+ CONFIG_KDB_CONTINUE_CATASTROPHIC == 2. If your kernel has the LKCD
+ patch and LKCD is configured to take a dump then KDB forces a dump.
+ Whether or not a dump is taken, KDB forces a reboot.
+ When KDB is not active (/proc/sys/kernel/kdb == 0) and a catastrophic
+ error occurs, the following steps are automatic, no human
+ intervention is required.
+ CONFIG_KDB_CONTINUE_CATASTROPHIC == 0 (default) or 1. KDB attempts
+ to continue - no guarantees that the kernel is still usable.
+ CONFIG_KDB_CONTINUE_CATASTROPHIC == 2. If your kernel has the LKCD
+ patch and LKCD is configured to take a dump then KDB automatically
+ forces a dump. Whether or not a dump is taken, KDB forces a
+ reboot.
+ If you are not sure, say 0. Read Documentation/kdb/dump.txt before
+ setting to 2.
+
+config KDB_USB
+ bool "Support for USB Keyboard in KDB (OHCI only)"
+ depends on KDB && USB_OHCI_HCD
+ help
+ If you want to use kdb from a OHCI USB keyboard then say Y here. If you
+ say N then kdb can only be used from a PC (AT) keyboard or a serial
+ console.

+/* ANSI and traditional C compatibility macros
+
+ ANSI C is assumed if __STDC__ is #defined.
+
+ Macro ANSI C definition Traditional C definition
+ ----- ---- - ---------- ----------- - ----------
+ ANSI_PROTOTYPES 1 not defined
+ PTR `void *' `char *'
+ PTRCONST `void *const' `char *'
+ LONG_DOUBLE `long double' `double'
+ const not defined `'
+ volatile not defined `'
+ signed not defined `'
+ VA_START(ap, var) va_start(ap, var) va_start(ap)
+
+ Note that it is safe to write "void foo();" indicating a function
+ with no return value, in all K+R compilers we have been able to test.
+
+ For declaring functions with prototypes, we also provide these:
+
+ PARAMS ((prototype))
+ -- for functions which take a fixed number of arguments. Use this
+ when declaring the function. When defining the function, write a
+ K+R style argument list. For example:
+
+ char *strcpy PARAMS ((char *dest, char *source));
+ ...
+ char *
+ strcpy (dest, source)
+ char *dest;
+ char *source;
+ { ... }
+
+
+ VPARAMS ((prototype, ...))
+ -- for functions which take a variable number of arguments. Use
+ PARAMS to declare the function, VPARAMS to define it. For example:
+
+ int printf PARAMS ((const char *format, ...));
+ ...
+ int
+ printf VPARAMS ((const char *format, ...))
+ {
+ ...
+ }
+
+ For writing functions which take variable numbers of arguments, we
+ also provide the VA_OPEN, VA_CLOSE, and VA_FIXEDARG macros. These
+ hide the differences between K+R <varargs.h> and C89 <stdarg.h> more
+ thoroughly than the simple VA_START() macro mentioned above.
+
+ VA_OPEN and VA_CLOSE are used *instead of* va_start and va_end.
+ Immediately after VA_OPEN, put a sequence of VA_FIXEDARG calls
+ corresponding to the list of fixed arguments. Then use va_arg
+ normally to get the variable arguments, or pass your va_list object
+ around. You do not declare the va_list yourself; VA_OPEN does it
+ for you.
+
+ Here is a complete example:
+
+ int
+ printf VPARAMS ((const char *format, ...))
+ {
+ int result;
+
+ VA_OPEN (ap, format);
+ VA_FIXEDARG (ap, const char *, format);
+
+ result = vfprintf (stdout, format, ap);
+ VA_CLOSE (ap);
+
+ return result;
+ }
+
+
+ You can declare variables either before or after the VA_OPEN,
+ VA_FIXEDARG sequence. Also, VA_OPEN and VA_CLOSE are the beginning
+ and end of a block. They must appear at the same nesting level,
+ and any variables declared after VA_OPEN go out of scope at
+ VA_CLOSE. Unfortunately, with a K+R compiler, that includes the
+ argument list. You can have multiple instances of VA_OPEN/VA_CLOSE
+ pairs in a single function in case you need to traverse the
+ argument list more than once.
+
+ For ease of writing code which uses GCC extensions but needs to be
+ portable to other compilers, we provide the GCC_VERSION macro that
+ simplifies testing __GNUC__ and __GNUC_MINOR__ together, and various
+ wrappers around __attribute__. Also, __extension__ will be #defined
+ to nothing if it doesn't work. See below.
+
+ This header also defines a lot of obsolete macros:
+ CONST, VOLATILE, SIGNED, PROTO, EXFUN, DEFUN, DEFUN_VOID,
+ AND, DOTS, NOARGS. Don't use them. */
