thorpej fae2a1befd Add `show malloc' to dump the internal state of the MALLOC_DEBUG code. 2001-08-17 01:00:10 +00:00
bjh21 286faf2070 Extra sanity checking on ELF headers: Make sure the bootloader actually
loaded (or claims to have loaded) everything we need.
2001-07-31 22:31:47 +00:00
bjh21 34c3239d32 Don't depend on the bootloader's having loaded the .shstrtab section
in order to load the symbol table.  Instead of using the sections
called ".symtab" and ".strtab", use the first SYMTAB section (the
ELF spec says there should currently only be one) and the STRTAB
section that's linked to it.  I believe this is more robust, and it
certainly makes life easier for the bootloader.

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.
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.

	<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.

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...
