Since commit 4652f1640e029e1f2433fa77ba6af285 "virtio-9p: add savevm
handlers", if the user hot-unplugs a quiescent 9p device and live
migrates, the source QEMU crashes before migration completetion...
This happens because virtio-9p devices have a realize handler which
calls virtio_init() and register_savevm(). Both calls store pointers
to the device internals, that get dereferenced during migration even
if the device got unplugged.
This patch simply adds an unrealize handler to perform minimal
cleanup and avoid the crash. Hot unplug of non-quiescent 9p devices
is still not supported in QEMU, and not supported by linux guests
either.

blk_attach_dev() fails here only when we're working for device
"sdhci-pci" (which already attached the backend), and then we don't
want to attach a second time. If we ever create another failure mode,
we're setting up ourselves to using the same backend from multiple
frontends, which is likely to end in tears. Can't clean this up this
close to the release, so mark it FIXME.

We currently fuse controller and card into a single device model, but
we intend qomify things properly and separate the two. The properties
that really belong to the card would then have to somehow pass-through
to the card's properties. To avoid that complication, either mark
them experimental or drop them.
Properties "capareg", "maxcurr" and the usual PCI device properties
belong to the controller. Property "drive" belongs to the card;
rename it to "x-drive". Properties "logical_block_size",
"physical_block_size", "min_io_size", "opt_io_size",
"discard_granularity" belong to the card, but have no effect; drop
them.

The official way of enabling dataplane is through the "iothread"
property that references an iothread object created by "-object

probably easier to just drop it:

With this change, access to invalid/unimplemented device registers are
logged as a "guest error" rather than aborting qemu with
hw_error. This enables drivers for similar devices (e.g. SMSC 9221),
by simply ignoring the unimplemented writes. It's also closer to what
real hardware does.

e1000 driver in Win2k12 is really well rotten. It 100% hangs on shutdown
of UP VM under flood ping. The guest checks card state and reinjects
itself interrupt in a loop. This is fatal for UP machine.
There is no good way to fix this misbehavior but to kludge it. The
emulation has interrupt throttling register aka ITR which limits
interrupt rate and allows the guest to proceed this phase.
There is no problem with this kludge for Linux guests - it adjust the
value of it itself.
On the other hand according to the initial research in
commit e9845f0985f088dd01790f4821026df0afba5795
Author: Vincenzo Maffione <v.maffione@gmail.com>

e1000: add interrupt mitigation support
...
Interrupt mitigation boosts performance when the guest suffers from
an high interrupt rate (i.e. receiving short UDP packets at high packet
rate). For some numerical results see the following link
http://info.iet.unipi.it/~luigi/papers/20130520-rizzo-vm.pdf
this should also boost performance a bit.

prop_get_fdt() misuses the visitor API: when fdt is null, it doesn't
visit anything. object_property_get_qobject() happily
object_property_get_qobject(). Amazingly, the latter survives the
misuse. Turns out we've papered over it long before prop_get_fdt()
existed, in commit 1d10b44.
However, commit 6c2f9a1 changed how we paper over it, and as a side

realize method
In 1811e64 'hw/virtio: Add PCIe capability to virtio devices', the
QEMU_PCI_CAP_EXPRESS capability was added to virtio's pci_dev, within
'virtio_pci_realize' - the pci device object realization method.
This occurs to late, as 'pci_qdev_realize' (DeviceClass.realize of
TYPE_PCI_DEVICE) has already been called, without knowing that the
device instance is indeed an "express" instance, thus allocating
insufficient pci config space.
As a result, device may crash upon attempt to write to the PCIE config
space.
Fix, by arming the QEMU_PCI_CAP_EXPRESS capability early in virtio-pci's
own DeviceClass realize method.
This also makes code cleaner, as 'virtio_pci_realize' may now access the
'pci_is_express' predicate when needed.

If you run a qemu advertising VERSION_1 with an old kernel where
vhost did not yet support VERSION_1, you'll end up with a device
that is {modern pci|ccw revision 1} but does not advertise VERSION_1.
This is not a sensible configuration and is rejected by the Linux
guest drivers.
To fix this, add a ->post_plugged() callback invoked after features
have been queried that can handle the VERSION_1 bit being withdrawn
and change ccw to fall back to revision 0 if VERSION_1 is gone.
Note that pci is _not_ fixed; we'll need to rethink the approach
for the next release but at least for pci it's not a regression.

Present code uses @size==UINT64_MAX to initialize IOMMU. It infers that it
can map any 64-bit IOVA whatsoever. But in fact, the largest DMA range for
each PCI Device on s390x is from ZPCI_SDMA_ADDR to ZPCI_EDMA_ADDR. The largest
value is returned from hardware, which is to indicate the largest range
hardware can support. But the real IOMMU size for specific PCI Device is
obtained once qemu intercepts mpcifc instruction that guest is requesting a
DMA range for that PCI Device. Therefore, before intercepting mpcifc instruction,
qemu cannot be aware of the size of IOMMU region that guest will use.
Moreover, iommu replay during device initialization for the whole region in
4k steps takes a very long time.
In conclusion, this patch intializes IOMMU region for each PCI Device when
intercept mpcifc instruction which is to register DMA range for the PCI Device.
And then, destroy IOMMU region when guest wants to deregister IOAT.

old_mmio
The taihu_cpld_writel() function had an obvious typo that meant that

versions of clang will detect and warn about this:
hw/ppc/ppc405_boards.c:481:1: warning: all paths through this function will call itself [-Winfinite-recursion]
Fix this by converting taihu_cpld from the legacy old_mmio accessors

The device's guest interface and its QEMU user interface are
flawed^Whotly debated. We'll resolve that in the next development
cycle, probably by deprecating the device in favour of a cleaned up,
but not quite compatible revision.
To avoid adding more baggage to the soon-to-be-deprecated interface,
mark property "memdev" as experimental, by renaming it to "x-memdev".

The minimum RAM check logic for the Xiilnx EP108 was off by one,
which caused a false positive. Correct the logic to only print
warnings when the RAM is below 0x8000000.

"werror=report" would free the req in virtio_blk_handle_rw_error, we

vhost, pc: fixes for 2.5
Fixes all over the place.
This also re-enables a test we disabled in 2.5 cycle
now that there's a way not to get a warning from it.

ich calls acpi_gpe_init with length ICH9_PMIO_GPE0_LEN so
ICH9_PMIO_GPE0_LEN/2 bytes are allocated, but then the full
ICH9_PMIO_GPE0_LEN bytes are migrated.
As a quick work-around, allocate twice the memory.
We'll probably want to tweak code to avoid
migrating the extra ICH9_PMIO_GPE0_LEN/2 bytes,
but that is a bit trickier to do without breaking
migration compatibility.

Upon activating an interrupt, set the corresponding priority bit in the
APR/NSAPR registers without touching the currently set bits. In the event
of nested interrupts, the GIC will then have the information it needs to
restore the priority of the pre-empted interrupt once the higher priority
interrupt finishes execution.

Stop directly accessing the Object::properties field data
structure and instead use the formal object property iterator
APIs. This insulates the code from future data structure
changes in the Object struct.
