ddb running on crash dumps, but with two notable changes:
- Breakpoints, watches, etc are obviously never going to work so they
are not handled.
- You can pipe output to the shell, e.g. ps | grep foo
Items remaining to be done:
- Port it to architectures other than i386. This isn't difficult, just
a case of making db_disasm.c/db_trace.c or their equivalent compile
and work.
- Make more of the "show" commands work, e.g "show uvmexp".
types of changes:
- Add a few new methods to replace stuff like p_find(), CPU_INFO_FOREACH.
- Use db_read_bytes() instead of accessing kernel structures directly,
and similar changes.
- Add ifdef _KERNEL where the above hasn't been done, and an XXX comment.
target after the recent addition of BFD_DETERMINISTIC_OUTPUT to libbfd.
The list of architectures is not complete, but these were the
ones I had readily-available toolchains for. The rest will be
dealt with a little later, by me or someone else.
which don't have EXT_RFA and IPCB support. From hme(4) driver and
FreeBSD's fxp(4). Tested on i82559.
XXX: Probably we should have a common function to parse RX packet headers
XXX: to handle a raw checksum value and share it among hme(4) and gem(4) etc.
already powered down. This change prevents PCI bus exceptions
(indicated by NMI) when, for example, I detach the whole device
tree on a Soekris net4521:
com1: detached
NMI ... going to debugger
Stopped in pid 0.1 (system) at netbsd:sipcom_stop+0x4d: pushl $0
db{0}> continue
NMI ... going to debugger
Stopped in pid 0.1 (system) at netbsd:sipcom_stop+0x149: addl $0x10,%e

db{0}> continue
sip0: detached
(On the AMD Elan SC520, the NMI occurs at the instruction after
the write or, if the write was posted, at either that instruction
or some later one.)
enabled:
- don't enable interrupts before calling uhci_run()
- check if the controller's interrupt is enabled in uhci_intr()
The issue is that uhci_run() may tsleep(), uhci_intr1() may be called before
uhci_run() is complete and disable it because it found it halted.
Now a uhci controller can be successfully exported to a NetBSD Xen domU :)
will share the interrupt with the domU and xen will wait for domain0 to
ack the interrupt too. Now devices that don't share an interrupt with
a device in domain0 works too.
Make sure the same PCI bus isn't published multiple times.
file, we conditionally define MIN and MAX.)
Including sys/param.h unconditionally like this seems unportable (in
view of the fact that file is built as a host tool), but other parts of
the file sources already include sys/param.h, so this change doesn't
make it worse.
This might fix PR 40539 from Brad Parker.
This patches the false branch of the Makefile as the true branch is only
used for cross-compiling of texinfo with the internal build system.
This avoids the termcap dependency as noticed in PR 40810.
NetBSD conventional bswap16, bswap32, and bswap64 functions or macros.
In a non-tools build, include <sys/types.h> and <machine/bswap.h> to
get definitions of these functions. In a tools build, rely on the
functions or macros being provided by nbtool_config.h, but don't incluce
<machine/bswap.h> (which might not exist in a cross build).
This should address a problem building on OpenBSD, which has swap16,
swap32, and swap64 macros that conflicted with the local definitions.
The problem was reported by Alexander Bluhm, but this patch is quite
different from the one he suggested.
these files use __weak_alias causes build failures under OpenBSD,
because the OpenBSD __weak_alias macro expects the caller to supply a
semicolon, but the NetBSD __weak_alias macro supplies its own semicolon.
Attempt to fix this by avoiding the use of __weak_alias during a tools
build.
prints something that does not look like an identifier, then use uname
-m instead. (Cygwin prints "unknown", and OpenBSD prints a long string
containing several spaces; this code should handle both.)
