The rerror/werror policies are implemented in the devices, so that's
where they should be configured. In comparison to the old options in
-drive, the qdev properties are only added to those devices that
actually support them.
If the option isn't given (or "auto" is specified), the setting of the
BlockBackend is used for compatibility with the old options. For block
jobs, "auto" is the same as "enospc".

As cache.writeback is a BlockBackend property and as such more related
to the guest device than the BlockDriverState, we already removed it
from the blockdev-add interface. This patch adds the new way to set it,
as a qdev property of the corresponding guest device.
For example: -drive if=none,file=test.img,node-name=img
-device ide-hd,drive=img,write-cache=off

Currently, we use memory_region_is_mapped() to detect if the host
backend memory is being used. This works if the memory is directly
mapped into guest's address space, however, it is not true for
nvdimm as it uses aliased memory region to map the memory. This is
why this bug can happen:
https://bugzilla.redhat.com/show_bug.cgi?id=1352769

If a node name instead of a BlockBackend name is specified as the driver
for a guest device, an anonymous BlockBackend is created now.
The order of operations in release_drive() must be reversed in order to
avoid a use-after-free bug because now blk_detach_dev() frees the last
reference if an anonymous BlockBackend is used.
usb-storage uses a hack where it forwards its BlockBackend as a property
to another device that it internally creates. This hack must be updated
so that it doesn't drop its original BB before it can be passed to the
other device. This used to work because we always had the monitor
reference around, but with node-names the device reference is the only
one now.

In practice the entry argument is always known at creation time, and
it is confusing that sometimes qemu_coroutine_enter is used with a
non-NULL argument to re-enter a coroutine (this happens in
block/sheepdog.c and tests/test-coroutine.c). So pass the opaque value
at creation time, for consistency with e.g. aio_bh_new.
Mostly done with the following semantic patch:
@ entry1 @
expression entry, arg, co;

- co = qemu_coroutine_create(entry);
+ co = qemu_coroutine_create(entry, arg);
...
- qemu_coroutine_enter(co, arg);

except for the aforementioned few places where the semantic patch

The Global Interrupt Controller (GIC) is responsible for mapping each
internal and external interrupt to the correct location for servicing.
The internal representation of registers is different from the specification
in order to consolidate information for each GIC Interrupt Sources and Virtual
Processors with same functionalities. For example SH_MAP00_VP00 registers are
defined like each bit represents a VP but in this implementation the equivalent
map_vp contains VP number in integer form for ease accesses. When it is being
accessed via read write functions an internal data is converted back into the
original format as the specification.

The interval timer is similar to the CP0 Count/Compare timer within
each processor. The difference is the GIC_SH_COUNTER register is global
to the system so that all processors have the same time reference.
To ease implementation, all VPs are having its own QEMU timer but sharing
global settings and registers such as GIC_SH_CONFIG.COUTNSTOP and
GIC_SH_COUNTER.
MIPS GIC Interval Timer does support upto 64 bits of Count register but

The current implementation of hot-unplug handler is abrupt. Any pci
operation will be just rejected if pci device is unconfigured. Thus a
pci device can not be reset or destroyed in a right, smooth and safe
way.
Improve this as follows:
- Notify the guest via a HP_EVENT_DECONFIGURE_REQUEST(0x303) event in
the unplug handler, giving it a chance to deconfigure the device via
sclp and allowing us to continue hot-unplug afterwards.
- Set up a timer that will generate the HP_EVENT_CONFIGURE_TO_STBRES
(0x304) event as before if the guest did not react after an adequate
time.

To support definitions of s390 pci attributes in Qemu cmdline, we have
to make current S390PCIBusDevice struct inherit DeviceState and add
three properties for it. Currently we only support definitions of uid
and fid.
'uid' is optionally defined by users, identifies a zpci device and
must be defined with a 16-bit and non-zero unique value.
'fid' ranges from 0x0 to 0xFFFFFFFF. For fid property, we introduce a
new PropertyInfo by the name of s390_pci_fid_propinfo with our special
setter and getter. As 'fid' is optional, introduce 'fid_defined' to
track whether the user specified a fid.
'target' field is to direct qemu to find the corresponding generic PCI
device. It is equal to the 'id' value of one of generic pci devices.
If the user doesn't specify 'id' parameter for a generic pci device,
its 'id' value will be generated automatically and use this value as
'target' to create an associated zpci device.
If the user did not specify 'uid' or 'fid', values are generated

Currently each zpci device holds its own DMA address space and memory
region. At the same time, all instances of zpci device are stored in
S390pciState. So duirng the initialization of S390pciState, all zpci
devices are created and then all DMA address spaces are created. Thus,
when initializing pci devices, their corresponding DMA address spaces
could be found.
But zpci qdev will be introduced later. Zpci device may be initialized
and plugged afterwards generic pci device. So we should initialize all
DMA address spaces and memory regions before initializing zpci devices.
We introduce a new struct named S390PCIIOMMU. And a new field of
S390pciState, which is an array to store all instances of S390PCIIOMMU,
is added so that qemu pci code could find the corresponding DMA
address space when initializing a generic pci device. And this should
be done before the connection of a zpci device and a generic pci
device is built.

The previous patch moved virtual css bridge and bus out from
virtio-ccw, but kept the direct reference of virtio-ccw specific
unplug function inside css-bridge.c.
To make the virtual css bus and bridge useful for non-virtio devices,
this introduces a common unplug function pointer "unplug" to call
specific virtio-ccw unplug parts. Thus, the tight coupling to
virtio-ccw can be removed.
This unplug pointer is a member of CCWDeviceClass, which is introduced
as an abstract device layer called "ccw-device". This layer is between
DeviceState and specific devices which are plugged in virtual css bus,
like virtio-ccw device. The specific unplug handlers should be assigned
to "unplug" during initialization.

Currently, common base layers virtual css bridge and bus are
defined in hw/s390x/virtio-ccw.c(h). In order to support
multiple types of devices in the virtual channel subsystem,
especially non virtio-ccw, refactoring work needs to be done.
This work is just a pure code move without any functional change
except dropping an empty function virtual_css_bridge_init() and
virtio_ccw_busdev_unplug() changing. virtio_ccw_busdev_unplug()
is specific to virtio-ccw but gets referenced from the common
virtual css bridge code. To keep the functional changes to a
minimum we export this function from virtio-ccw.c and continue
to reference it inside virtual_css_bridge_class_init()

Currently CPUClass->parse_features() is used to parse -cpu

But considering that features specified by -cpu apply to every
created CPU instance, it doesn't make sense to parse the same
features string for every CPU created. It also makes every target
that cares about parsing features string explicitly call
CPUClass->parse_features() parser, which gets in a way if we
consider using generic device_add for CPU hotplug as device_add
has not a clue about CPU specific hooks.
Turns out we can use global properties mechanism to set
properties on every created CPU instance for a given type. That
way it's possible to convert CPU features into a set of global
properties for CPU type specified by -cpu cpu_model and common
Device.device_post_init() will apply them to CPU of given type
automatically regardless whether it's manually created CPU or CPU

Rather than making the dealloc visitor track of stack of pointers
remembered during visit_start_* in order to free them during
visit_end_*, it's a lot easier to just make all callers pass the
same pointer to visit_end_*. The generated code has access to the
same pointer, while all other users are doing virtual walks and
can pass NULL. The dealloc visitor is then greatly simplified.
All three visit_end_*() functions intentionally take a void**,
even though the visit_start_*() functions differ between void**,
GenericList**, and GenericAlternate**. This is done for several
reasons: when doing a virtual walk, passing NULL doesn't care
what the type is, but when doing a generated walk, we already
have to cast the caller's specific FOO* to call visit_start,
while using void** lets us use visit_end without a cast. Also,
an upcoming patch will add a clone visitor that wants to use
the same implementation for all three visit_end callbacks,
which is made easier if all three share the same signature.
For visitors with already track per-object state (the QMP visitors
via a stack, and the string visitors which do not allow nesting),
add an assertion that the caller is indeed passing the same
pointer to paired calls.

BlockBackend has only a single pointer to its guest device, so it makes
sure that only a single guest device is attached to it. device-add
returns an error if you try to attach a second device to a BB. In order
to make the error message nicer, -device that manually connects to a
if=none block device get a different message than -drive that implicitly
creates a guest device. The if=... option is stored in DriveInfo.
However, since blockdev-add exists, not every BlockBackend has a
DriveInfo any more. Check that it exists before we dereference it.
QMP reproducer resulting in a segfault:
{"execute":"blockdev-add","arguments":{"options":{"id":"disk","driver":"file","filename":"/tmp/test.img"}}}
{"execute":"device_add","arguments":{"driver":"virtio-blk-pci","drive":"disk"}}

Sector-based limits are awkward to think about; in our on-going
quest to move to byte-based interfaces, convert max_transfer_length
and opt_transfer_length. Rename them (dropping the _length suffix)
so that the compiler will help us catch the change in semantics
across any rebased code, and improve the documentation. Use unsigned
values, so that we don't have to worry about negative values and
so that bit-twiddling is easier; however, we are still constrained
by 2^31 of signed int in most APIs.
When a value comes from an external source (iscsi and raw-posix),
sanitize the results to ensure that opt_transfer is a power of 2.

Making all callers special-case 0 as unlimited is awkward,
and we DO have a hard maximum of BDRV_REQUEST_MAX_SECTORS given
our current block layer API limits.
In the case of scsi, this means that we now always advertise a
limit to the guest, even in cases where the underlying layers
previously use 0 for no inherent limit beyond the block layer.

Internal flag msi_used is uncesessary, msi_uninit() could be called
directly, msi_enabled() is enough to check device msi state.
But for migration compatibility, keep the field in structure.

megasas overwrites user configuration when msi_init fail to flag internal msi
state, which is unsuitable. megasa_use_msi() is unnecessary, we can call
msi_uninit() directly when unrealize, even no need to call msi_enabled() first.

msi_init() reports errors with error_report(), which is wrong
when it's used in realize().
Fix by converting it to Error.
Fix its callers to handle failure instead of ignoring it.
For those callers who don't handle the failure, it might happen:
when user want msi on, but he doesn't get what he want because of
msi_init fails silently.

This adds proper support for translating real mode addresses based
on the combination of HV and LPCR bits. This handles HRMOR offset
for hypervisor real mode, and both RMA and VRMA modes for guest
real mode. PAPR mode adjusts the offsets appropriately to match the
RMA used in TCG, but we need to limit to the max supported by the
implementation (16G).
