even when the boot sector signature isn't there, by setting a bit in
RTC CMOS.  It was added back in 2006 (commit 52ca8d6a).

Two years later, commit 0ecdffbb added monitor command boot_set.
Implemented by new function pc_boot_set().  It unconditionally clears
the floppy signature bit in CMOS.

Commit e0f084bf added -boot option once to automatically change the
boot order on first reset.  Reuses pc_boot_set(), thus also clears the
floppy signature bit.  Commit d9346e81 took care to preserve this
behavior.

Thus, -no-fd-bootchk applies to any number of boots.  Except it
applies just to the first boot with -boot once, and never after
boot_set.  Weird.  Make it stick instead: set the bit according to

vl: Fix -boot order and once regressions, and related bugs

Option "once" sets up a different boot order just for the initial
boot.  Boot order reverts back to normal on reset.  Option "order"
changes the normal boot order.

The reversal is implemented by reset handler restore_boot_devices(),
which takes the boot order to revert to as argument.
restore_boot_devices() does nothing on its first call, because that
must be the initial machine reset.  On its second call, it changes the
boot order back, and unregisters itself.

Because we register the handler right when -boot gets parsed, we can
revert to an incorrect normal boot order, and multiple -boot can
interact in funny ways.

Here's how things work without -boot once or order:

* boot_devices is "".

* main() passes machine->boot_order to to machine->init(), because
  boot_devices is "".  machine->init() configures firmware
  accordingly.  For PC machines, machine->boot_order is "cad", and
  pc_cmos_init() writes it to RTC CMOS, where SeaBIOS picks it up.

Now consider -boot order=:

* boot_devices is "".

* -boot order= sets boot_devices to "" (no change).

* main() passes machine->boot_order to to machine->init(), because
  boot_devices is "", as above.

  Bug: -boot order= has no effect.  Broken in commit e4ada29e.

  firmware accordingly.  For PC machines, pc_cmos_init() writes the
  boot order to RTC CMOS.

* main() calls qemu_system_reset().  This runs reset handlers.

  - restore_boot_devices() gets called with argument "".  Does
    nothing, because it's the first call.

11 years agowdt_i6300esb: fix vmstate versioning

wdt_i6300esb: fix vmstate versioning

When this VMSD was introduced it's version fields were set to
sizeof(I6300State), making them essentially random from build to build,
version to version.

To fix this, we lock in a high version id and low minimum version id to
support old->new migration from all prior versions of this device's
state. This should work since the device state has not changed since
its introduction.

The potentially breaks migration from 1.5+ to 1.5, but since the
versioning was essentially random prior to this patch, new->old
migration was not consistently functional to begin with.
