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

 1999-10-14 18:42:15 +00:00
jdolecek 7f589dba84 rename the MD Debugger() to cpu_Debugger() 
add MI Debugger() which switches to console if wscons is used prior
to calling cpu_Debugger()

mycroft 26a93b8985 Do branch forking for inst_return() instructions, too. 1998-11-25 06:38:03 +00:00
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
thorpej 970e60efb8 - Use proclists[], rather than checking allproc and zombproc explicitly.

the current 'bootblock' method, like the Shark, which preloads and preformats
the symbol table right in the boot code.

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.  :-)

when symbol tables are loaded don't belong to the user interaction,

thorpej d9f8d88a35 Fixup the software single-step code (used on architectures where there 
is no hardware support for single-stepping):
- Fix branch prediction and delay slot computation (for the MIPS).
- Correctly deal with branch taken vs. branch not taken cases, and
  self-branches.
- General cleanup, including types botches.
Partially from Mach 3, with a bunch of cleanup work by me.

thorpej 1d7e4d35d9 Update prototypes for new function signatures. Note, the ddb_init() 
signature is currently different for the DB_AOUT_SYMBOLS vs. the
DB_ELF_SYMBOLS cases. (XXX)
 1997-06-26 01:14:16 +00:00
thorpej 84c0797eda Use db_expr_t rather than int when reading a value from the kernel 
address space, to avoid type-size problems.
 1997-06-26 01:13:11 +00:00
thorpej 0ae10b0d60 In the db_breakpoint_t, use a db_expr_t to store the original instruction, 
not an int.
 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.
 1997-06-26 01:11:00 +00:00
thorpej c95e0b0782 Use db_expr_t rather than int in a few strategic places to avoid

thorpej c14ce368af Define db_onpanic variable; if non-zero, the DDB will be entered when 
the kernel panics.  It may be initialized to 0 with the kernel option
"DDB_ONPANIC=0", and is patchable.  It may be changed at run-time
from within the DDB (as a DDB variable) or via the ddb.onpanic sysctl
node.

Export all DDB built-in variables via sysctl.
