* arch/i386/kdb/kdba_bt.c (kdba_bt_stack): Do not attempt a backtrace if
the code segment is not in the kernel.
* kdb/modules: Change modules from MX_OBJS to M_OBJS. Remove EXPORT_NOSYMBOLS.
2000-09-21 Keith Owens <kaos@melbourne.sgi.com>
* arch/i386/kernel/i386_ksyms.c: Move EXPORT_SYMBOLS for kdb to kdb/kdbmain.c.
* kdb/Makefile: Change kdb/kdbmain.o from O_OBJS to OX_OBJS.
* arch/i386/kernel/smp.c: Remove some #ifdef CONFIG_KDB. Remove kdbprivate.h.
* include/linux/kdb.h: Add kdb_print_state. Add KDB_STATE_WAIT_IPI.
* kdb/kdbmain.c (kdb): Only mark cpu as leaving if it is in KDB state. Maintain
WAIT_IPI state so a cpu is only driven through NMI once.
* arch/i386/kernel/smp.c (smp_kdb_stop): All state fiddling moved to kdb().
2000-09-20 Keith Owens <kaos@melbourne.sgi.com>
* include/linux/kdb.h: #define kdb() as (0) if kdb is not configured.
* arch/i386/kernel/traps.c: Remove some #ifdef CONFIG_KDB.
* include/linux/kdbprivate.h: Move per cpu state to kdb.h.
* include/linux/kdb.h: Add KDB_STATE_NO_WATCHDOG, KDB_STATE_PRINTF_LOCK.
Rename KDB_DEBUG_xxx to KDB_DEBUG_FLAG_xxx. Clean up debug flag
definitions.
* arch/i386/kernel/traps.c (nmi_watchdog_tick): Check no watchdog.
* kdb/kdbmain.c (kdb): Set no watchdog in normal kdb code.
* kdb/kdbmain.c (kdb_parse): Allow watchdog in commands.
* kdb/kdb_io.c (kdb_printf): No watchdog during printing. Clean up lock handling.
* kdb/kdbmain.c (kdb_set): Clean up debug flag handling.
2000-09-19 Juan J. Quintela <quintela@fi.udc.es>
* kdb/arch/i386/kdb/kdba_io.c: Allow kdb to compile without CONFIG_VT and/or
serial console.
2000-09-19 Keith Owens <kaos@melbourne.sgi.com>
* include/linux/kdb.h: Define KDB_DEBUG_STATE().
* kdb/kdbmain.c (kdb): Add kdb_print_state(), calls to KDB_DEBUG_STATE().
2000-09-16 Keith Owens <kaos@melbourne.sgi.com>
* Move to finer grained control over individual processors in kdb with
per cpu kdb state. Needed to allow ss[b] to only release one processor,
previously ss[b] released all processors. Also need to recover from
errors inside kdb commands, e.g. oops in kdbm_pg code.
* various:
Move global flags KDB_FLAG_SSB, KDB_FLAG_SUPRESS, KDB_FLAG_FAULT,
KDB_FLAG_SS, KDB_FLAG_SSBPT, kdb_active, to per cpu state and macros
KDB_STATE(xxx).
Replace kdb_flags & KDB_FLAG_xxx with KDB_FLAG(xxx).
Replace kdb_flags & KDB_DEBUG_xxx with KDB_DEBUG(xxx).
Replace specific tests with wrapper KDB_IS_RUNNING().
* various: Remove #ifdef CONFIG_SMP from kdb code wherever
possible. Simplifies the code and makes it much more readable.
* arch/i386/kdb/kdbasupport.c (kdb_setjmp): Record if we have reliable
longjmp data instead of assuming it is always set.
* various: Replace smp_kdb_wait with per cpu state, HOLD_CPU.
* init/main.c : Replace #ifdef KDB_DEBUG with KDB_DEBUG(CALLBACK).
* include/linux/kdbprivate.h: Separate command return codes from error
codes. Add more detailed command codes.
* arch/i386/kernel/traps.c (die): Change spin_lock_irq to
spin_lock_irqsave. Why did I do this?
* kdb/kdbmain.c (kdb_parse): Set per cpu flag CMD before executing kdb
command. More detailed return codes for commands that affect
processors.
* kdb/kdbmain.c (kdb_previous_event): New, check if any processors are
still executing the previous kdb event. Removes a race window where a
second event could enter kdb before the first had completely ended.
* kdb/kdbmain.c (kdb): Document all the concurrency conditions and how
kdb handles them. ss[b] now releases only the current cpu. Do not set
breakpoints when releasing for ss[b]. Recover from errors in kdb
commands. Check that we have reliable longjmp data before using it.
* various: Update return code documentation.
* kdb/kdb_bp.c (kdb_ss): Separate ss and ssb return codes.
* kdb/kdbsupport.c (kdb_ipi): Finer grained algorithm for deciding
whether to call send a stop signal to a cpu.
* arch/i386/kdb/kdba_bp.c (kdba_db_trap): Separate ss and ssb return
codes. Reinstall delayed software breakpoints per cpu instead of
globally. Changed algorithm for handling ss[b].
* arch/i386/kdb/kdba_bp.c (kdba_bp_trap): Match software breakpoints per
cpu instead of globally.
* include/linux/kdb.h: Bump version to kdb v1.5.
2000-09-16 Keith Owens <kaos@melbourne.sgi.com>
* kernel/sysctl.c (kern_table): add /proc/sys/kernel/kdb.
* init/main.c (parse_options): add boot flags kdb=on, kdb=off,
kdb=early.
* include/linux/sysctl.h (enum): add KERN_KDB.
* drivers/char/serial.c (receive_chars): check kdb_on.
* drivers/char/keyboard.c (handle_scancode): check kdb_on.
* arch/i386/kernel/traps.c (nmi_watchdog_tick): check kdb_on.
* arch/i386/config.in: add CONFIG_KDB_OFF.

* kdb/kdb_bt.c (kdb_bt): check environment variable BTAPROMPT.
* kdb/kdbsupport.c (kdb_ipi): ignore NMI for kdb_initial_cpu.
