tv 242cedc18c Add two new functions, db_format_radix() and db_format_hex(), which supplant
the former %r and %z nonstandard kprintf strings.

jhawk 67c55e543e Fix CTRL-T to behave properly. It should swaps the current and previous
characters, not the previous and second-to-previous.

jeffs 9349a51d66 Provide some info on what db_trap_callback() is for in the code. 2000-07-18 20:51:07 +00:00
jeffs 0e0c4d24e8 Move platform db_trap callback from arch/mips into ddb as suggested by
jhawk.  This callback is used by platform code to manage things like
watchdogs that should be disabled while in ddb.  Done as a callback
for processors such as mips that support lots of different systems.

eeh 74e5e4f040 Fix for:
7.      Numbers starting with [a-f] should work, but symbols
        of the same name should have priority.

jhawk e0b6c173e7 s/preserving ... bytes of symbol table/using ... bytes of symbol table/
"preserving" implies that the data may be copied and might otherwise
be freed, and that other data in the symbol table or sections of
the kernel might be freed, however there is no mechanism for these
things to take place, so "using" is clearer.

jhawk 21322c88b6 Observe deficiency in printfs reporting symbol table problems
before we have a message buffer.
2000-07-07 21:51:38 +00:00
jhawk d58fe92d14 Detect ELF sections (string and symbol tables) by looking them
up by name (in .shstrtab) instead of guessing based on section
type (and throwing away the small one). In addition to being cleaner,
multiple symbol tables are no longer and error condition, so
booting netbsd.gdb no longer results in ddb being unable to use
*any* symbols.

jhawk 92276a6ce3 "set" now displays the name of the variable, old value, and new value,
just as "write" does.

mrg f324eef2d2 remove include of <vm/vm.h> 2000-06-27 17:55:38 +00:00
mrg 2f159a1bac remove/move more mach vm header files:
<vm/pglist.h> -> <uvm/uvm_pglist.h>
	<vm/vm_inherit.h> -> <uvm/uvm_inherit.h>
	<vm/vm_kern.h> -> into <uvm/uvm_extern.h>
	<vm/vm_object.h> -> nothing
	<vm/vm_pager.h> -> into <uvm/uvm_pager.h>

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.

jhawk a639b800ee In db_command(), fix indentation and add a missing db_skip_to_eol() which
previously caused the next command following a ","-style repitition
to not be properly executed.

sommerfeld cb31de55ed In the "reboot" and (badly misnamed) "sync" commands, clear db_recover
before calling cpu_reboot() (which never returns) so we can debug
faults occurring in cpu_reboot().

jhawk 74ee4f350f Only define db_show_arptab if NARP>1;

jhawk 84ceb5dfe7 Fix long-standing inconsistency between manapage and code.
The "ditto" character is " (double-quote); not , (comma) as
indicated in the manpage; and not ' (single-quote) as indicated
in the man.old -style manpage from which the mdoc manpage was derived.

Some other versions of ddb use single-quote for this feature, and this
part of the code may change again in the near future, but the documentation
now affects reality now.

soren 6d6d07abe5 #include <sys/systm.h> for the snprintf() prototype. 2000-06-06 18:50:56 +00:00
jhawk be69eea9ae First cut at an outline of stuff to do. 2000-06-06 05:41:54 +00:00
jhawk b756e7384d Stop using DDB-specific "%n" kprintf() format specifier. This was
important as db_sym() can be called through printf() rather than
db_printf(), causing a trap as the standard %n usage is invoked.

The DDB-specific %n code should disappear from subr_prf.c soon...

sommerfeld bdc8251646 Change printing of cpu number in the prompt in the MULTIPROCESSOR case 2000-05-28 19:03:55 +00:00
jhawk 8e44b27348 Rename the machine-specific stack trace printing functions
from db_stack_trace_cmd() to db_stack_trace_print(),
and add an additional argument, a function pointer for an
output routine (i.e. printf() or db_printf()).

Add db_stack_trace_cmd() in db_command.[ch], calling
db_stack_trace_print() with db_printf() as the printer.

Move count==-1 special handling from db_stack_trace_print() [nee
db_stack_trace_cmd()] to db_stack_trace_cmd() [nascent here].

Again, I'm unable to test compilation on all affected platforms,
so advance apologies for potential brokenness.
2000-05-26 03:34:24 +00:00
jhawk f3528d725d Interface change: db_printsym() takes a third argument, pr, a function
pointer indicating how to print the symbol. This allows db_printsym()
to called in places where db_printf() is not an appropriate output
function.

While straightforward, apologies in advance if I've introduced any minor
syntax errors; I was unable to test compilation this on all the affected
platforms.

thorpej 20c7af8a35 Fix a printf format. 2000-05-23 06:06:10 +00:00
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.

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).

jhawk cc732067b7 "p" should be an alias for "print", and was until "ps" was added.
Now it is, again.

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.

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
