079bff693b transactions: Invoke clean() after everything else
Invoke the transaction drivers' .clean() methods only after all
.commit() or .abort() handlers are done.

This makes it easier to have nested transactions where the top-level
transactions pass objects to lower transactions that the latter can
still use throughout their commit/abort phases, while the top-level
transaction keeps a reference that is released in its .clean() method.

(Before this commit, that is also possible, but the top-level
transaction would need to take care to invoke tran_add() before the
lower-level transaction does.  This commit makes the ordering
irrelevant, which is just a bit nicer.)

e5cba10ee1 hw/intc/arm_gicv3: Support multiple redistributor regions
Our GICv3 QOM interface includes an array property
redist-region-count which allows board models to specify that the
registributor registers are not in a single contiguous range, but
split into multiple pieces.  We implemented this for KVM, but
currently the TCG GICv3 model insists that there is only one region.
You can see the limit being hit with a setup like:
  qemu-system-aarch64 -machine virt,gic-version=3 -smp 124

Add support for split regions to the TCG GICv3.  To do this we switch
from allocating a simple array of MemoryRegions to an array of
GICv3RedistRegion structs so that we can use the GICv3RedistRegion as
the opaque pointer in the MemoryRegion read/write callbacks.  Each
GICv3RedistRegion contains the MemoryRegion, a backpointer allowing
the read/write callback to get hold of the GICv3State, and an index
which allows us to calculate which CPU's redistributor is being
accessed.

Note that arm_gicv3_kvm always passes in NULL as the ops argument
to gicv3_init_irqs_and_mmio(), so the only MemoryRegion read/write
callbacks we need to update to handle this new scheme are the
gicv3_redist_read/write functions used by the emulated GICv3.

01b5ab8cc0 hw/intc/arm_gicv3: Move checking of redist-region-count to arm_gicv3_common_realize
The GICv3 devices have an array property redist-region-count.
Currently we check this for errors (bad values) in
gicv3_init_irqs_and_mmio(), just before we use it.  Move this error
checking to the arm_gicv3_common_realize() function, where we
sanity-check all of the other base-class properties. (This will
always be before gicv3_init_irqs_and_mmio() is called, because
that function is called in the subclass realize methods, after
they have called the parent-class realize.)

The motivation for this refactor is:
 * we would like to use the redist_region_count[] values in
   arm_gicv3_common_realize() in a subsequent patch, so we need
   to have already done the sanity-checking first
 * this removes the only use of the Error** argument to
   gicv3_init_irqs_and_mmio(), so we can remove some error-handling
   boilerplate

This allows to power off pci devices.  In "off" state the devices will
not be visible.  No pci config space access, no pci bar access, no dma.

Default state is "on", so this patch (alone) should not change behavior.

Use case:  Allows hotplug controllers implement slot power.  Hotplug
controllers doing so should set the inital power state for devices in
the ->plug callback.

c318bef762 hw/acpi/ich9: Add compat prop to keep HPC bit set for 6.1 machine type
To solve issues [1-2] the Hot Plug Capable bit in PCIe Slots will be
turned on, while the switch to ACPI Hot-plug will be done in the
DSDT table.

Introducing 'x-keep-native-hpc' property disables the HPC bit only
in 6.1 and as a result keeps the forced 'reserve-io' on
pcie-root-ports in 6.1 too.

ef149763a8 rcu: Introduce force_rcu notifier
The drain_rcu_call() function can be blocked as long as an RCU reader
stays in a read-side critical section. This is typically what happens
when a TCG vCPU is executing a busy loop. It can deadlock the QEMU
monitor as reported in https://gitlab.com/qemu-project/qemu/-/issues/650 .

This can be avoided by allowing drain_rcu_call() to enforce an RCU grace
period. Since each reader might need to do specific actions to end a
read-side critical section, do it with notifiers.

Prepare ground for this by adding a notifier list to the RCU reader
struct and use it in wait_for_readers() if drain_rcu_call() is in
progress. An API is added for readers to register their notifiers.

This is largely based on a draft from Paolo Bonzini.

1bf4d3294b monitor: Fix find_device_state() for IDs containing slashes
Recent commit 6952026120 "monitor: Tidy up find_device_state()"
assumed the function's argument is "the device's ID or QOM path" (as
documented for device_del).  It's actually either an absolute QOM
path, or a QOM path relative to /machine/peripheral/.  Such a relative
path is a device ID when it doesn't contain a slash.  When it does,
the function now always fails.  Broke iotest 200, which uses relative
path "vda/virtio-backend".

It fails because object_resolve_path_component() resolves just one
component, not a relative path.

The obvious function to resolve relative paths is
object_resolve_path().  It picks a parent automatically.  Too much
magic, we want to specify the parent.  Create new
object_resolve_path_at() for that, and use it in find_device_state().

450e0f28a4 docs: remove non-reference uses of single backticks
The single backtick markup in ReST is the "default role". Currently,
Sphinx's default role is called "content". Sphinx suggests you can use
the "Any" role instead to turn any single-backtick enclosed item into a
cross-reference.

This is useful for things like autodoc for Python docstrings, where it's
often nicer to reference other types with `foo` instead of the more
laborious :py:meth:`foo`. It's also useful in multi-domain cases to
easily reference definitions from other Sphinx domains, such as
referencing C code definitions from outside of kerneldoc comments.

Before we do that, though, we'll need to turn all existing usages of the
"content" role to inline verbatim markup wherever it does not correctly
resolve into a cross-refernece by using double backticks instead.

e86a93f554 virtio-gpu: splitting one extended mode guest fb into n-scanouts
When guest is running Linux/X11 with extended multiple displays mode enabled,
the guest shares one scanout resource each time containing whole surface
rather than sharing individual display output separately. This extended frame
is properly splited and rendered on the corresponding scanout surfaces but
not in case of blob-resource (zero copy).

This code change lets the qemu split this one large surface data into multiple
in case of blob-resource as well so that each sub frame then can be blitted
properly to each scanout.

v2: resizing qemu console in virtio_gpu_update_dmabuf to scanout's width and
    height

v3: updating stub function of virtio_gpu_update_dmabuf to match the type

357af9be5c plugins: try and make plugin_insn_append more ergonomic
Currently we make the assumption that the guest frontend loads all
op code bytes sequentially. This mostly holds up for regular fixed
encodings but some architectures like s390x like to re-read the
instruction which causes weirdness to occur. Rather than changing the
frontends make the plugin API a little more ergonomic and able to
handle the re-read case.

Stuff will still get strange if we read ahead of the opcode but so far
no front ends have done that and this patch asserts the case so we can
catch it early if they do.

58d7d4c786 usb-storage: tag usb_msd_csw as packed struct
Without this the struct has the wrong size: sizeof() evaluates
to 16 instead of 13.  In most cases the bug is hidden by the
fact that guests submits a buffer which is exactly 13 bytes
long, so the padding added by the compiler is simply ignored.

But sometimes guests submit a larger buffer and expect a short
transfer, which does not work properly with the wrong struct
size.

f9429c6790 monitor: introduce HumanReadableText and HMP support
This provides a foundation on which to convert simple HMP commands to
use QMP. The QMP implementation will generate formatted text targeted
for human consumption, returning it in the HumanReadableText data type.

The HMP command handler will simply print out the formatted string
within the HumanReadableText data type. Since this will be an entirely
formulaic action in the case of HMP commands taking no arguments, a
custom command handler is provided.

Thus instead of registering a 'cmd' callback for the HMP command, a
'cmd_info_hrt' callback is provided, which will simply be a pointer
to the QMP implementation.

Instead of invoking select_watchdog_action from both HMP and command line,
go directly from HMP to QMP and use QemuOpts as the intermediary for the
command line.

This makes -watchdog-action explicitly a shortcut for "-action watchdog",
so that "-watchdog-action" and "-action watchdog" override each other
based on the position on the command line; previously, "-action watchdog"
always won.

68d7946648 linux-aio: add dev_max_batch parameter to laio_io_unplug()
Between the submission of a request and the unplug, other devices
with larger limits may have been queued new requests without flushing
the batch.

Using the new `dev_max_batch` parameter, laio_io_unplug() can check
if the batch exceeds the device limit to flush the current batch.
