+ This option provides a built-in kernel debugger. The built-in

+ 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

+ 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.

+ KDB can be extended by adding your own modules, in directory

+ 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.

+ 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_LKCD_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.

+ guarantees that the kernel is still usable.
+ CONFIG_KDB_CONTINUE_CATASTROPHIC == 2. If your kernel has the LKCD

+ Whether or not a dump is taken, KDB forces a reboot.

+ 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,

+ 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. */

+
+ * New KDB USB interface, Aaron Young <ayoung@sgi.com>
+ * 1. This patch allows KDB to work with any Host Contoller driver
+ * and call the correct HC driver poll routine (as long as the
+ * HC driver provides a .kdb_poll_char routine via it's
+ * associated hc_driver struct).
+ * 2. Hotplugged keyboards are now recognized by KDB.
+ * 3. Currently KDB can only make use of 1 USB type keyboard.
+ * New code can handle up to 8 attached keyboards - input is
+ * multiplexed from all of them while in kdb.
+ * kdb v4.4-2.6.23-common-2.

+/* Tracking registers by decoding the instructions is quite a bit harder than
+ * doing the same tracking using compiler generated information. Register
+ * contents can remain in the same register, they can be copied to other
+ * registers, they can be stored on stack or they can be modified/overwritten.
+ * At any one time, there are 0 or more copies of the original value that was
+ * supplied in each register on input to the current function. If a register
+ * exists in multiple places, one copy of that register is the master version,
+ * the others are temporary copies which may or may not be destroyed before the
+ * end of the function.
+ *
+ * The compiler knows which copy of a register is the master and which are
+ * temporary copies, which makes it relatively easy to track register contents
+ * as they are saved and restored. Without that compiler based knowledge, this
+ * code has to track _every_ possible copy of each register, simply because we
+ * do not know which is the master copy and which are temporary copies which
+ * may be destroyed later.
+ *
+ * It gets worse: registers that contain parameters can be copied to other
+ * registers which are then saved on stack in a lower level function. Also the
+ * stack pointer may be held in multiple registers (typically RSP and RBP)
+ * which contain different offsets from the base of the stack on entry to this
+ * function. All of which means that we have to track _all_ register
+ * movements, or at least as much as possible.
+ *
+ * Start with the basic block that contains the start of the function, by
+ * definition all registers contain their initial value. Track each
+ * instruction's effect on register contents, this includes reading from a
+ * parameter register before any write to that register, IOW the register
+ * really does contain a parameter. The register state is represented by a
+ * dynamically sized array with each entry containing :-
+ *
+ * Register name
+ * Location it is copied to (another register or stack + offset)
+ *
+ * Besides the register tracking array, we track which parameter registers are
+ * read before being written, to determine how many parameters are passed in
+ * registers. We also track which registers contain stack pointers, including
+ * their offset from the original stack pointer on entry to the function.
+ *
+ * At each exit from the current basic block (via JMP instruction or drop
+ * through), the register state is cloned to form the state on input to the
+ * target basic block and the target is marked for processing using this state.
+ * When there are multiple ways to enter a basic block (e.g. several JMP
+ * instructions referencing the same target) then there will be multiple sets
+ * of register state to form the "input" for that basic block, there is no
+ * guarantee that all paths to that block will have the same register state.
+ *
+ * As each target block is processed, all the known sets of register state are
+ * merged to form a suitable subset of the state which agrees with all the
+ * inputs. The most common case is where one path to this block copies a
+ * register to another register but another path does not, therefore the copy
+ * is only a temporary and should not be propogated into this block.
+ *
+ * If the target block already has an input state from the current transfer
+ * point and the new input state is identical to the previous input state then
+ * we have reached a steady state for the arc from the current location to the
+ * target block. Therefore there is no need to process the target block again.
+ *
+ * The steps of "process a block, create state for target block(s), pick a new
+ * target block, merge state for target block, process target block" will
+ * continue until all the state changes have propogated all the way down the
+ * basic block tree, including round any cycles in the tree. The merge step
+ * only deletes tracking entries from the input state(s), it never adds a
+ * tracking entry. Therefore the overall algorithm is guaranteed to converge
+ * to a steady state, the worst possible case is that every tracking entry into
+ * a block is deleted, which will result in an empty output state.
+ *
+ * As each instruction is decoded, it is checked to see if this is the point at
+ * which execution left this function. This can be a call to another function
+ * (actually the return address to this function) or is the instruction which
+ * was about to be executed when an interrupt occurred (including an oops).
+ * Save the register state at this point.
+ *
+ * We always know what the registers contain when execution left this function.
+ * For an interrupt, the registers are in struct pt_regs. For a call to
+ * another function, we have already deduced the register state on entry to the
+ * other function by unwinding to the start of that function. Given the
+ * register state on exit from this function plus the known register contents
+ * on entry to the next function, we can determine the stack pointer value on
+ * input to this function. That in turn lets us calculate the address of input
+ * registers that have been stored on stack, giving us the input parameters.
+ * Finally the stack pointer gives us the return address which is the exit
+ * point from the calling function, repeat the unwind process on that function.
+ *
+ * The data that tracks which registers contain input parameters is function
+ * global, not local to any basic block. To determine which input registers
+ * contain parameters, we have to decode the entire function. Otherwise an
+ * exit early in the function might not have read any parameters yet.
