simonb 18b2f7e6a1 Add a port to IBM's PPC405GP Reference Board (the "walnut")
by Eduardo Horvath and Simon Burge of Wasabi Systems.

IBM 4xx series CPU features:
 - New pmap and revised trap handler.
 - Support on-chip timers, PCI controller, UARTs
 - Framework for on-chip ethernet and watchdog timer.
General PowerPC features:
 - Add in-kernel PPC floating point emulation
 - New in{,4}_cksum that is between 1.5 and 5 times faster than the
   old version depending on CPU type.
General changes:
 - Kernel support for generic dbsym-style symbols.

ross 818513678d The current API for MD support doesn't directly support the documented /u
option to show reg /u.  Fix this by adding a modif[ier] field to struct
db_variable.

thorpej 1c3a62e066 Sprinkle pmap_update() calls after calls to:
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).

These calls are relatively conservative.  It may be possible to
optimize these a little more.

jhawk 35483d9169 alphabetize db_command tables 2001-02-11 21:12:24 +00:00
jdolecek 9818f641c3 make db_command_table[] const; since there is no way to dynamically extend
or modify the table at the moment, there is no functionality lost.
See also the discussion on tech-kern (Subject: 'machine' DDB command).
2001-01-24 20:54:41 +00:00
jdolecek 8b24036797 Require the machine-dependant DDB commands to be in db_machine_command_table[]
and link it directly to db_command_table[] so that it's not necessary
to do this at runtime. Make db_machine_command_table[] const on all ports.
g/c now unneded stuff, like db_machine_commands_install(), db_machine_init()

Patch written by enami.

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.

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.

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.

	<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

sommerfeld cb31de55ed In the "reboot" and (badly misnamed) "sync" commands, clear db_recover

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.

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.
