atatat 282eb9c623 Unfold the KDEREF() macros a little, and tweak the LOCKDEBUG detection
code, to detect a KDEREF failure instead of simply aborting.  If the
KDEREF fails, we're obviously not_using_lockdebug().

atatat a068aea23a Find the buf_map symbol, so that the submap can be labeled properly. 2004-01-06 14:01:19 +00:00
yamt 9eeb053922 redo the previous in a different way; use vm_map_min/max macros. 2003-09-17 22:06:50 +00:00
yamt 4a1d5a0332 update lockdebug detection to follow uvm_map.h rev.1.35.
(vm_map.header.{start,end} was swapped.)

atatat c9c88988f6 Though I cannot reproduce the failure (which I suspect is rather
system dependent), the analysis provided in PR misc/22089 is correct.
Therefore, allocate one more slot and suck one more slot from the
kernel.

atatat 535d709586 Build main.c with LOCKDEBUG defined so that it gets the larger kbit
definition.  Since we're now passing it into pmap.c which is already
compiled that way, it would be nice if it was the right size.

Also, fix a memset bug that caused a segmentation fault when printing
the kernel's vm_map.

wiz 817f471b97 Sort options in usage. 2003-04-16 12:15:07 +00:00
atatat a88940798c Add some more intricate groveler options:
-A address   Dumps the vm_amap structure found at address.

     -E address   Dumps the vm_map_entry structure found at address.

     -S address   Dumps the vmspace structure found at address.

     -V address   Dumps the vm_map structure found at address.

This required reorganizing the code a little, which led to some
cleanup (yay!).  These new methods are executed without any extra
privileges, so you need read access on /dev/mem or on the kernel core
into which you are digging.

This should be useful for, eg, examining amaps are corrupt when being
destroyed, which can cause a kernel panic (and, hence, are no longer
connected to a map entry, or the map entry is no longer connected to a
vm_map/vmspace).

The options in the man page have also been reorganized.

he d614a5830d Introduce a "size_t" variable for use with sysctl(3).
Fixes compile problem observed on evbarm.

atatat 2242d20a09 Add the capability to dump the struct vm_amap and the am_anon,
am_bckptr, am_slots, and am_anon data, if the vm_map_entry has an
amap.  This adds three new debug "bits" to the -D argument, so the
namei cache dumping "bit" has been moved up.

Also, change the * that gets emitted with -vv to indicate the number
of pages skipped and the size of the area (in kilobytes).

atatat 6d45c1cd99 Clean up code in places, add some more (possible) submap names, make
better use of the submap names when dumping the kernel map, clean up
the "interface" between the main and LOCKDEBUG dependent pmap modules,
and make the heap identification work better.

atatat 3535ff5eb9 Print the string as if it's a string. Don't print the pointer. It's
useless for the non-omniscient (who, by definition, would have no need
for this program anyway).

atatat 80f8e56ac7 More properly handle the setgid privileges that we have, casting them
out if using them might be unsafe.

atatat a26b7f4d29 Make pmap work on LOCKDEBUG *and* non-LOCKDEBUG kernels (previously it
would fail in spectacular ways on LOCKDEBUG kernels) by compiling the
groveler code twice (the second time with LOCKDEBUG defined so that
the appropriate structures get larger in the right way).  We currently
decide if we are operating on a kernel with LOCKDEBUG enabled if the
kernel's vm_map has referential integrity between a few pointers
and/or values.

Also, if you use more than one -v, you get a * on a line by itself in
between gaps in entries.  It makes finding gaps much easier visually.
