jhawk 41ebaaaf09 Add a "sifting" command to ddb (named from the Sun OpenPROM command of 
the same name); it searches the symbol table(s) for all symbols matching
a given substring, and prints.

Extremely useful for when you forget that critical symbol name.

Also, with /F support (cf. "ls -F") to print a char indicating the
symbol type.
 2000-05-22 14:49:10 +00:00
jhawk ca31d672e2 Install "show arptab" (db_show_arptab) in the ddb command tree. 
Move prototype from netinet/if_inarp.h to ddb/db_interface.h.
Change function to have standard ddb parameters (though they're
ignored).
 2000-05-20 03:08:41 +00:00
jhawk cc732067b7 "p" should be an alias for "print", and was until "ps" was added. 
Now it is, again.
 2000-05-15 19:56:43 +00:00
jhawk a71de73182 From kern/9569. 
Preserve ddb's idea of "count" from one command to the next if
repeating a command via hitting newline.

thorpej fc96443d15 New callout mechanism with two major improvements over the old 
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

jdolecek 8b2a23fb1a db_cmd_list(): variable ``width'' might have be used uninitialized, initialize 
it to 0
 1999-11-02 23:53:31 +00:00
lukem 4a2b49cb31 - change db_cmd_list() to list commands vertically rather than horizontally 
- sort entries in the various command tables, so that the `help' lists
  are easier to use. this included hacking db_machine_commands_install()
  to search for the "machine" entry to change the `more cmds' pointer,
  rather than assuming it was the first entry
- add a `sync' command, which is effectively `reboot 0x100'.
- remove db_help_cmd(); it was unused (and was almost a duplicate of
  db_cmd_list()).
- move some extern decls to db_output.h, since they're used in more than one
  place now
- rename NEXT_TAB to DB_NEXT_TAB and move to db_output.h

jonathan 3ac3cbcfb8 Add options DDB_FROMCONSOLE and sysctl ddb.fromconsole, analagous to 
DDB_ONPANIC. Lets user ignore breaks but enter DDB on panic.  Intended
for machines where debug on panic is useful, but DDB entry is not,
(public-access console, or terminal-servers which send spurious breaks)

Add new ddb hook, console_debugger(), which decides whether or not to
ignore console ddb requests. Console drivers should be updated to call
console_debugger(), not Debugger(), in response to serial-console
break or ddb keyboard sequence.
 1998-10-29 21:22:32 +00:00

pk df2b26547d If `SOFTWARE_SSTEP' is defined then kgdb_stub.c needs the single-step 
emulation in db_run.c:

	- re-arrange `db_*_single_step()' and `db_*_temp_breakpoint()' -
	  which are only used in the `SOFTWARE_SSTEP' case - so these
	  are available to the KGDB code.
	- make other code in db_run.c conditional on `DDB'.

mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current. 
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

  self-branches.
- General cleanup, including types botches.
Partially from Mach 3, with a bunch of cleanup work by me.

thorpej 84c0797eda Use db_expr_t rather than int when reading a value from the kernel

 1997-06-26 01:12:05 +00:00
thorpej 76fbbf772d A few small changes to make it easier to support non-a.out symbol table 
formats in DDB:
- Reverse the sense of the symbol format #ifdef... i.e. instead of
  "#ifndef DB_NO_AOUT", use "#ifdef DB_AOUT_SYMBOLS".  This is pulled
  in from <machine/db_machdep.h>.
- Change the signature of X_db_sym_init().  Instead of int * and char *,
  it now takes void *'s for the start and end of the symbol table.
- In X_db_sym_init(), check that the pointer to the beginning of
  the symbol table is aligned.
- X_db_symbol_values() now takes a "db_symtab_t *symtab" argument.

from within the DDB (as a DDB variable) or via the ddb.onpanic sysctl
node.
