christos c60f6fad95 fix userland build, by moving all the unused stuff inside ifdef _KERNEL 2013-10-19 15:20:52 +00:00
christos fa04e235ed remove the new command not the old one. 2013-01-06 04:17:27 +00:00
christos cc78507c3a remove previous, dmesg just works. 2013-01-06 03:34:52 +00:00
christos 81736cc9cd Add "show dmesg" that prints the contents of the message buffer. 2013-01-06 03:23:55 +00:00
christos cedbce7adf Add "show panic" that shows the current panic string. two ports had it, and 
it could be easily made MI.

rmind 4b760398c3 Remove MALLOC_DEBUG and MALLOCLOG, which is dead code after malloc(9) move 
to kmem(9).  Note: kmem(9) has debugging facilities under DEBUG/DIAGNOSTIC.
However, expensive kmguard and debug_freecheck have to be enabled manually.

mrg c09a267949 set panicstr to "reboot forced via kernel debugger" when rebooting 
from ddb, similar to how sync from ddb works.

this avoids various asserts and other issues during ddb reboot.

mrg 8169e46991 move and rename the uvm history code out of uvm_stat to "kernhist". 
rename "UVMHIST" option to enable the uvm histories.

TODO:
- make UVMHIST properly depend upon KERNHIST
- enable dynamic registration of histories.  this is mostly just
  allocating something in a bitmap, and is only for viewing multiple
  histories in a merged form.


tested on amd64 and sparc64.

christos 2a672d40b3 Add:

        /a == argument is an address of any lwp
	/p == argument is a pid [default]

mrg 06dd613f03 extend 'show event' to take /i /t and /m modifiers, to select interrupt, 
trap or misc event types.  you can mix them with /f as well, to show all
including zero events for traps and misc, "show event/ftm"
 2009-06-05 04:31:47 +00:00
ad 912b4160fd Make 'show event', 'dmesg' work with crash(8). 
XXX dmesg fails exactly the same way as /sbin/dmesg.

nakayama 3a99fdb328 Avoid "warning: cast from pointer to integer of different size" 
on 32-bit sparc64 kernels.
 2009-03-11 13:29:44 +00:00
ad cd6b1c8f08 Make ddb compile and work in userspace. Mostly this is comprised of three 
types of changes:

- Add a few new methods to replace stuff like p_find(), CPU_INFO_FOREACH.

- Use db_read_bytes() instead of accessing kernel structures directly,
  and similar changes.

- Add ifdef _KERNEL where the above hasn't been done, and an XXX comment.

yamt f68e4571e5 - fix vmem unittest. rename VMEM_DEBUG so that it won't be abused again. 
- reimplement vmem sanity checks with less code duplication.
- reimplement ddb vmem-related commands in a more consistent ways.
  remove automatic whatis.

haad 128703a537 Fix my bug introduced in rev 1.98 of db_command.c where command prefix 
not ambiguous in one table was choosed even if it was ambiguous in another
table in same list. Also apply more KNF rules.

nakayama 4cb83f9c6e Make DDB shows right register values on 32-bit sparc64 kernels.

uwe 85dcbb2bb9 db_cmd_search: When we compare names we'd better stop at the nul byte. 
Don't flip-flop between found and ambiguous.  (hi, martin!)

martin 28da38cbee Fix command name matching, avoid jumps to null function pointers and 
some minor cosmetics.

martin cd2cd2dd63 Do another setjmp right before entering the command loop, we do not want 
to execute the on-enter commands again on errors.
 2007-10-08 15:06:26 +00:00
martin 9b58206ecf Some cleanup: 
- When registering command tables, make sure the builtin commands are
   already registered
 - Make the command table entry structure private
 - Do not bother to store the number of commands in a table, we can quickly
   calc that if needed.
 2007-10-02 08:47:26 +00:00
martin cadfc6aaa0 No need to db_init_commands() early any more - it will happen on first 
entry to ddb.
 2007-10-01 22:05:15 +00:00
martin 463076317b Special case the initialization of builtin command tables to avoid using 
malloc. Fixes PR kern/37042.
Allow "mach" commands registered by LKMs even if there is no builtin
mach command for the arch.
 2007-10-01 22:01:38 +00:00
martin 34bb6e19fd Minor clenaup - db_cmd_loop_done is a bool nowadays, so use true/false 
instead of 0/1.
Also make db_init_commands() non-static.
 2007-09-23 23:55:54 +00:00
martin 99423a9d7c Simplify the "tables are already setup" test. 
Print a message on unknown commands (as we used to do before) and get rid
of the now unused macro previously used for that.

rmind 67d703cf25 Import of POSIX Asynchronous I/O. 
Seems to be quite stable. Some work still left to do.

Please note, that syscalls are not yet MP-safe, because
of the file and vnode subsystems.
