This reverts commit 618e8665db.
This is the first in a series of 10 commits that revert (in reverse
order) the changes to add the <acpi-hotplug-bridge state='on|off'/>
switch to libvirt domain XML, which unfortunately needs to be removed
due to QEMU developers discovering a flaw with the design of the QEMU
commandline switch used to implement the libvirt switch that will
likely result in a new and different method of selecting hotplug
modes. Because the libvirt switch has not been in any official
releases of libvirt, we are still able to remove it completely, rather
than deprecating it.
The original commits began with commit
58ba0f6a3d. The other original commit

Starting with QEMU-6.2 started accepting a JSON object as argument for
'-device' which will also become the only syntax considered stable by
qemu in the future.
Since libvirt was recently converted to generate the properties via JSON
to begin wit we can start using it on the commandline as well, by simply
enabling the QEMU_CAPS_DEVICE_JSON capability, which we do by probing
for the 'json-cli' feature flag of 'device_add'.
Normally a change which changes a commandline output should be happening
only after the impacted real-caps test files are forked in the version
preceding the change, but in this case it's not necessary as the logic
for generating the device properties stays identical and we just change
the output format (avoid conversion). Additionally we still have a lot
of tests validating the conversion to the old commandline options.

then passed to virNetSocketNewConnectCommand() where it is freed

1) The deallocation happens on a different level than allocation,

This change introduces a new libvirt sub-element <pci> under
<features> that can be used to configure all pci related features.
Currently the only sub-sub element supported by this sub-element is
'acpi-bridge-hotplug' as shown below:
<features>
<pci>
<acpi-bridge-hotplug state='on|off'/>
</pci>
</features>
The above option is only available for the QEMU driver, for x86 guests
only. It is a global option, affecting all PCI bridge controllers on
the guest.
The 'acpi-bridge-hotplug' option enables or disables ACPI hotplug
support for cold-plugged pci bridges. Examples of bridges include the
PCI-PCI bridge (pci-bridge controller) for pc (i440fx) machinetypes,
or PCIe-PCI bridges and pcie-root-port controllers for q35
machinetypes.
For pc machinetypes in x86, this option has been available in QEMU
since version 2.1. Please see the following changes in qemu repo:
9e047b982452c6 ("piix4: add acpi pci hotplug support")
133a2da488062e ("pc: acpi: generate AML only for PCI0 devices if PCI
bridge hotplug is disabled")
For q35 machinetypes, this was introduced in QEMU 6.1 with the
following changes in qemu repo:
(a) c0e427d6eb5fef ("hw/acpi/ich9: Enable ACPI PCI hot-plug")
(b) 17858a16950860 ("hw/acpi/ich9: Set ACPI PCI hot-plug as default on
Q35")
The reasons for enabling ACPI based hotplug for PCIe (q35) based
machines (as opposed to native hotplug) are outlined in (b). There are
use cases where users would still want to use native
hotplug. Therefore, this config option enables users to choose either
ACPI based hotplug or native hotplug for bridges (for example for pcie
root port controller in q35 machines).
Qemu capability validation checks have also been added along with
related unit tests to exercise the new conf option.

qemu added support for i440fx specific global boolean flag
PIIX4_PM.acpi-pci-hotplug-with-bridge-support
around version 2.1. This flag is enabled by default. When disabled, it
turns off acpi pci hotplug for cold plugged pci bridges in i440fx
machine types.
Very recently, in qemu version 6.1, the same global option was also
added for q35 machine types as well.
ICH9-LPC.acpi-pci-hotplug-with-bridge-support
This option turns on or off acpi based hotplug for cold plugged pcie
bridges like pcie root ports. This flag is also enabled by
default. Please refer to the following qemu changes:
c0e427d6eb5fef ("hw/acpi/ich9: Enable ACPI PCI hot-plug")
17858a16950860 ("hw/acpi/ich9: Set ACPI PCI hot-plug as default on Q35")
This patch adds the corresponding qemu capabilities in libvirt. For
i440fx, the capability is detected as
QEMU_CAPS_PIIX_ACPI_HOTPLUG_BRIDGE. For q35, the capability is
detected as QEMU_CAPS_ICH9_ACPI_HOTPLUG_BRIDGE.
Please note that the test specific qemu capabilities .replies files
has already been updated as a part of regular refreshing them when a
new qemu version is released. Hence, no updates to those files are

Nothing special is happening here. All important changes were
done when for 'virtio-pmem' (adjusting the code to put virtio
memory on PCI bus, generating alias using
qemuDomainDeviceAliasIndex(). The only bit that might look
suspicious is no prealloc for virtio-mem. But if you think about
it, the whole purpose of this device is to change amount of
memory exposed to guest on the fly. There is no point in locking
the whole backend in memory.
Signed-off-by: Michal Privoznik <mprivozn@redhat.com>

The virtio-mem is paravirtualized mechanism of adding/removing
memory to/from a VM. A virtio-mem-pci device is split into blocks
of equal size which are then exposed (all or only a requested
portion of them) to the guest kernel to use as regular memory.
Therefore, the device has two important attributes:
1) block-size, which defines the size of a block
2) requested-size, which defines how much memory (in bytes)
is the device requested to expose to the guest.
The 'block-size' is configured on command line and immutable
throughout device's lifetime. The 'requested-size' can be set on
the command line too, but also is adjustable via monitor. In
fact, that is how management software places its requests to
change the memory allocation. If it wants to give more memory to
the guest it changes 'requested-size' to a bigger value, and if it
wants to shrink guest memory it changes the 'requested-size' to a
smaller value. Note, value of zero means that guest should
release all memory offered by the device. Of course, guest has to
cooperate. Therefore, there is a third attribute 'size' which is
read only and reflects how much memory the guest still has. This
can be different to 'requested-size', obviously. Because of name
clash, I've named it 'current' and it is dealt with in future
commits (it is a runtime information anyway).
In the backend, memory for virtio-mem is backed by usual objects:
memory-backend-{ram,file,memfd} and their size puts the cap on
the amount of memory that a virtio-mem device can offer to a
guest. But we are already able to express this info using <size/>
under <target/>.
Therefore, we need only two more elements to cover 'block-size'
and 'requested-size' attributes. This is the XML I've came up
with:
<memory model='virtio-mem'>
<source>
<nodemask>1-3</nodemask>
<pagesize unit='KiB'>2048</pagesize>
</source>
<target>
<size unit='KiB'>2097152</size>
<node>0</node>
<block unit='KiB'>2048</block>
<requested unit='KiB'>1048576</requested>
</target>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</memory>
I hope by now it is obvious that:
1) 'requested-size' must be an integer multiple of
'block-size', and
2) virtio-mem-pci device goes onto PCI bus and thus needs PCI
address.
Then there is a limitation that the minimal 'block-size' is
transparent huge page size (I'll leave this without explanation).

Some userspace (such as a test program, or an optimized memory allocation
library) may want to know the size (in bytes) of a transparent hugepage::

Since this size depends on the host architecture and the kernel
it won't change whilst libvirtd is running. Therefore, we can use
