This is a mostly-mechanical conversion that creates a new flat
union 'Netdev' QAPI type that covers all the branches of the
former 'NetClientOptions' simple union, where the branches are
now listed in a new 'NetClientDriver' enum rather than generated
from the simple union. The existence of a flat union has no
change to the command line syntax accepted for new code, and
will make it possible for a future patch to switch the QMP
command to parse a boxed union for no change to valid QMP; but
it does have some ripple effect on the C code when dealing with
the new types.
While making the conversion, note that the 'NetLegacy' type
remains unchanged: it applies only to legacy command line options,
and will not be ported to QMP, so it should remain a wrapper
around a simple union; to avoid confusion, the type named
'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions'
in its place. Then, in the C code, we convert from NetLegacy to
Netdev as soon as possible, so that the bulk of the net stack
only has to deal with one QAPI type, not two. Note that since
the old legacy code always rejected 'hubport', we can just omit
that branch from the new 'NetLegacyOptions' simple union.

The following sequence of tests discovered a problem in IDE emulation:
1. Send DMA write to IDE device 0
2. Send CMD_FLUSH_CACHE to same IDE device which will be failed by block
layer using blkdebug script in tests/ide-test:test_retry_flush
When doing DMA request ide/core.c will set s->retry_unit to s->unit in
ide_start_dma. When dma completes ide_set_inactive sets retry_unit to -1.
After that ide_flush_cache runs and fails thanks to blkdebug.
ide_flush_cb calls ide_handle_rw_error which asserts that s->retry_unit
== s->unit. But s->retry_unit is still -1 after previous DMA completion
and flush does not use anything related to retry.
This patch restricts retry unit assertion only to ops that actually use
retry logic.

QEMU supports ARI on downstream ports and assigned devices may support
ARI in their extended capabilities. The endpoint ARI capability
specifies the next function, such that the OS doesn't need to walk
each possible function, however this next function is relative to the
host, not the guest. This leads to device discovery issues when we
combine separate functions into virtual multi-function packages in a
guest. For example, SR-IOV VFs are not enumerated by simply probing
the function address space, therefore the ARI next-function field is
zero. When we combine multiple VFs together as a multi-function
device in the guest, the guest OS identifies ARI is enabled, relies on
this next-function field, and stops looking for additional function
after the first is found.
Long term we should expose the ARI capability to the guest to enable
configurations with more than 8 functions per slot, but this requires
additional QEMU PCI infrastructure to manage the next-function field
for multiple, otherwise independent devices. In the short term,
hiding this capability allows equivalent functionality to what we
currently have on non-express chipsets.

If CPU core addition or removal is allowed in random order leading to
holes in the core id range (and hence in the cpu_index range), migration
can fail as migration with holes in cpu_index range isn't yet handled
correctly.
Prevent this situation by enforcing the addition in contiguous order
and removal in LIFO order so that we never end up with holes in
cpu_index range.

This ioctl() call to VFIO_IOMMU_SPAPR_TCE_REMOVE was left over from an
earlier version of the code and has since been folded into
vfio_spapr_remove_window().
It wasn't caught because although the argument structure has been removed,
the libc function remove() means this didn't trigger a compile failure.
The ioctl() was also almost certain to fail silently and harmlessly with
the bogus argument, so this wasn't caught in testing.

If the host has 8 threads/core and the guest is started with:
-smp cores=1,threads=4,maxcpus=12
It is possible to crash QEMU by doing:
(qemu) device_add host-spapr-cpu-core,core-id=16,id=foo
(qemu) device_del foo
Segmentation fault
This happens because spapr_core_unplug() assumes cpu_dt_id == core_id.
As long as cpu_dt_id is derived from the non-table cpu_index, this is
only true when you plug cores with contiguous ids.
It is safer to be consistent: the DR connector was created with an
index that is immediately written to cc->core_id, and spapr_core_plug()
also relies on cc->core_id.
Let's use it also in spapr_core_unplug().

U-boot does SPI timing calibration using DMA tranfers. To let the
initialization continue, we fake success by setting the DMA status of
the Interrupt Control Register.
For the moment, DMA support is not required as it is not used in
normal operation.

KVM adjusts the MPIDR of guest vcpus based on the architecture of
the host, 32-bit vs. 64-bit, and, for 64-bit, also on the type of
GIC the guest is using. To be consistent and improve SGI efficiency
we make the same adjustments for TCG as 64-bit KVM hosts. We neglect
to add consistency with 32-bit KVM hosts, as that would reduce SGI
efficiency and KVM is expected to change.
As MPIDR is a system register, and thus guest visible, we only make
adjustments for current and later versioned machines.

At the moment the following QEMU command line triggers an assertion
failure (minimal reproducer by Cole):
qemu-system-aarch64 \
-machine virt-2.6,accel=tcg \
-nodefaults \
-no-user-config \
-nographic -monitor stdio \
-device virtio-scsi-device,id=scsi0 \

-device scsi-hd,bus=scsi0.0,drive=d0 \
-drive file=foo.img,format=raw,if=none,id=d1 \
-device scsi-hd,bus=scsi1.0,drive=d1
qemu-system-aarch64: migration/savevm.c:615:
vmstate_register_with_alias_id:
Assertion `!se->compat || se->instance_id == 0' failed.
The reason is that the vmstate sections for the two scsi-hd devices are
not uniquely identifiable by name.
The direct parent buses of the scsi-hd devices -- scsi0.0 and scsi1.0 --
support the BusClass.get_dev_path member function. scsibus_get_dev_path()
formats a device path prefix with the help of its topologically parent
bus, and then appends the chan🆔lun triplet to it. For both scsi-hd
devices, this triplet is 0:0:0.
(Here we use "device path" in the QEMU migration sense, for vmstate
section identification, not in the OFW or UEFI device path senses.)
The virtio-scsi HBA is plugged into the virtio-mmio bus (implemented by
the internal VirtIOMMIOProxy device). This bus class
(TYPE_VIRTIO_MMIO_BUS) inherits, as its get_dev_path() member function,
the virtio_bus_get_dev_path() method from its parent class
(TYPE_VIRTIO_BUS).
virtio_bus_get_dev_path() does not format any kind of device address on
its own; "virtio addresses" are transport-specific. Therefore
virtio_bus_get_dev_path() asks the topologically parent bus of the proxy
object (implementing the specific virtio transport) to format the address
of the proxy object.
(For virtio-pci devices (where the proxy is an instance of VirtIOPCIProxy,
plugged into a PCI bus), this ends up in pcibus_get_dev_path().)
However, VirtIOMMIOProxy is usually (in practice: always) plugged into
"main-system-bus", the singleton TYPE_SYSTEM_BUS object. This BusClass
does not support formatting QEMU vmstate device paths at all (as
SysBusDevice objects can have zero or more IO ports and zero or more MMIO
regions). Hence the formatting request delegated from
virtio_bus_get_dev_path() gets answered with NULL.
The end result is that the two scsi-hd devices end up with the same device
path "0:0:0", which triggers the assert.
We can solve this by recognizing that virtio-mmio transports are
distinguished from each other by their base addresses in MMIO address
space. Implement virtio_mmio_bus_get_dev_path() as follows:
(1) The virtio device whose devpath is to be formatted resides on a
virtio-mmio bus that is implemented by a VirtIOMMIOProxy object. Ask
the parent bus of VirtIOMMIOProxy to format the device path of
VirtIOMMIOProxy, as a path prefix. (This is identical to what
virtio_bus_get_dev_path() does.)
(2) Append the base address of VirtIOMMIOProxy to the device path, such
as:
- virtio-mmio@000000000a003e00,
- virtio-mmio@000000000a003c00.
Given that these device paths are placed in the migration stream, step (2)
above, if done unconditionally, would break migration. So make that step
conditional on a new VirtIOMMIOProxy property, which is enabled for 2.7
machine types and later.

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".

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:

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);

expression entry, arg;
identifier co;

- Coroutine *co = qemu_coroutine_create(entry);

+ qemu_coroutine_enter(co);
except for the aforementioned few places where the semantic patch
stumbled (as expected) and for test_co_queue, which would otherwise
produce an uninitialized variable warning.
