Richard W.M. Jones [Fri, 24 Sep 2010 15:08:06 +0000 (16:08 +0100)]
Watchdog: disable watchdog timer when hard-rebooting a guest.

This commit causes the watchdog timer to be reset when a guest is
hard-rebooted.

The failure case previously was as follows:

  (a) guest boots, watchdog is enabled

  (b) guest does a reset eg:
        echo 'b' > /proc/sysrq-trigger
    (note that an ordinary /sbin/reboot wouldn't hit this case
    since as the watchdog daemon is shut down, the daemon would
    properly disable the watchdog device)

  (c) the reboot takes longer than the remaining time on the
    watchdog

  (d) the watchdog therefore fires during the reboot

  (e) probably the VM would just reboot again at this point which
    is pretty benign, but it could depend on the action that the
    user had selected for the watchdog

Now we use the qdev reset function to register a reset handler
which disables the timer.  Note the handler is called _either_
just after init _or_ when the guest reboots.

In the i6300esb case there is a small refactoring of the code so
that the device's internal state is now fully restored to defaults
on a reboot.

most devices are little endian (all PCI and ISA ones I'm aware of). Some

target native endian (fw_cfg).

So instead of assuming every device to be native endianness, let's move
to a model where the device tells us which endianness it's in.

correct migrate_set_speed's args_type

The args_type of migrate_set_speed in qmp-commands.hx is wrong.
When we set migrate speed by json, qemu will be core dumped.

This bug was caused by 07de3e60b05 and hence affects master only.

QMP: Drop dead code

The first if/else clause in handler_audit() makes no sense for two
reasons:

  1. this function is now called only by QMP code, so testing if
     it's a QMP call makes no sense anymore

  2. the else clause first asserts that there's no error in the
     monitor object, then it tries to free it!

Just drop it.

QMP: Fix default response regression

Commit 030db6e89d dropped do_info() usage from QMP and introduced
qmp_call_query_cmd(). However, the new function doesn't emit QMP's
default OK response when the handler doesn't return data.

Fix that by also calling monitor_protocol_emitter() when
ret_data == NULL, so that the default response is emitted.

Additional modifications were needed for this code change:

* alpha-dis.c: The local definition of MAX conflicts with
  a previous definition from osdep.h, so add an #undef.

* dis-asm.h: Add include for fprintf_function (qemu-common.h).
  The standard (now redundant) includes are removed.

* mis-dis.c: The definition of ARRAY_SIZE is no longer needed
  and must be removed (conflict with previous definition from
  qemu-common.h).

* sh4-dis.c: Remove some unneeded forward declarations.
