thorpej 1ab6db8e5f Fix printf format problems on Alpha. 1999-02-12 00:50:09 +00:00
augustss 332d7c138f Avoid arithmetic on `void *' since that's not ANSI C. 1999-01-08 18:10:35 +00:00
thorpej c89493522f - Make the ddb_init() interface consistent for a.out and ELF. 
- Allow DDB to run-time switch for a.out or ELF symbol table support.

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. 
- Add some comments about locking.

ross c291189ae9 Have to fix the `(int)curproc' lossage now; kernel builds die here on alpha. 
BTW, KNF requires the additional, not-technically-need `!= NULL'.

tv 00ede2160e Change ddb_init() for a.out to provision for kernels which are not booted by 
the current 'bootblock' method, like the Shark, which preloads and preformats
the symbol table right in the boot code.

thorpej 38f367e1a0 Whitespace. 1998-05-03 18:49:54 +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 d90485202c - add defopt's for UVM, UVMHIST and PMAP_NEW. 
- remove unnecessary UVMHIST_DECL's.
 1998-02-10 14:08:44 +00:00
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.  :-)

drochner 9d7d537acb Clean up usage of printf() vs db_printf(): The diagnostic messages 
when symbol tables are loaded don't belong to the user interaction,
their output lines should not be counted by ddb's builtin pager.

chuck e0ced7363a fix printf formatting of "ps" (aka "show all proc") so that lines never 
overflow (always hated that).

	/a == show process address info
	/n == show normal process info [currently the default]
	/w == show process wait/emul info

thorpej 5accaea913 Add support for Elf symbol tables to DDB, written from scratch by me. 
Known to work in DDB under NetBSD/alpha.

thorpej 9ec5f78d39 Pass the current DDB symbol table to X_db_symbol_values(). 1997-06-26 01:19:07 +00:00
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.
 1997-06-26 01:18:11 +00:00
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.
