commit d7346e614f ("acpi: x86: pcihp: add support hotplug on multifunction bridges")
added ACPI hotplug descriptions for cold plugged bridges for functions other
than 0. For all other devices, the ACPI hotplug descriptions are limited to
function 0 only. This change adds unit tests for this feature.
This test adds the following devices to qemu and then checks the changes
introduced in the DSDT table due to the addition of the following devices:
(a) a multifunction bridge device
(b) a bridge device with function 1
(c) a non-bridge device with function 2
In the DSDT table, we should see AML hotplug descriptions for (a) and (b).
For (a) we should find a hotplug AML description for function 0.
The following diff compares the DSDT table AML with the new unit test before
and after the change d7346e614f is introduced. In other words,
this diff reflects the changes that occurs in the DSDT table due to the change
d7346e614f .

PCI resource reserve capability should use LE format as all other PCI
things. If we don't then seabios won't boot:
=== PCI new allocation pass #1 ===
PCI: check devices
PCI: QEMU resource reserve cap: size 10000000000000 type io
PCI: secondary bus 1 size 10000000000000 type io
PCI: secondary bus 1 size 00200000 type mem

PCI: out of I/O address space
This became more important since we started reserving IO by default,
previously no one noticed.

the control virtqueue is also required to be coupled with the

number of datapath queue pairs plus the the number of control

Commit f3a8505656 ("qdev/qbus: add hidden device support") has
introduced a generic way to hide a device but it has modified
qdev_device_add() to check a specific option of the failover device,
"failover_pair_id", before calling the generic mechanism.
It's not needed (and not generic) to do that in qdev_device_add() because
this is also checked by the failover_hide_primary_device() function that
uses the generic mechanism to hide the device.

qemu-storage-daemon is launched with the vhost-user listen socket path.
The path is first unlinked before opening the listen socket. This
prevents stale UNIX domain socket files from stopping socket
initialization.
This behavior is undesirable in vhost-user-blk-test and the cause of a
bug:
There is a race condition in vhost-user-blk-test when QEMU launches
before QSD. It connects to the old socket that QSD unlinks and the
vhost-user connection is never serviced, resulting in a hang.
Pass the listen socket fd to QSD to maintain listen socket continuity
and prevent the lost connection.

The hide_device helper can be called several times for the same
devices as it shouldn't change any state and should only return an
information.
But not to rely anymore on QemuOpts we have introduced a new field
to store the parameters of the device and don't allow to update it
once it is done.
And as the function is called several times, we ends with:
warning: Cannot attach more than one primary device to 'virtio0'
That is not only a warning as it prevents to hide the device and breaks
failover.
Fix that by checking the device id.
Now, we fail only if the virtio-net device is really used by two different
devices, for instance:
-device virtio-net-pci,id=virtio0,failover=on,... \
-device vfio-pci,id=hostdev0,failover_pair_id=virtio0,... \
-device e1000e,id=e1000e0,failover_pair_id=virtio0,... \
will exit with:

Set -smp 1,maxcpus=288 to test for ACPI code that
deal with CPUs with large APIC ID (>255).
PS:
Test requires KVM and in-kernel irqchip support,
so skip test if KVM is not available.

Currently it is not possible to create tests that have KVM as a hard
requirement on a host that doesn't support KVM for tested target
binary (modulo going through the trouble of compiling out
the offending test case).
Following scenario makes test fail when it's run on non x86 host:
qemu-system-x86_64 -enable-kvm -M q35,kernel-irqchip=on -smp 1,maxcpus=288
This patch introduces qtest_has_accel() to let users check if accel is
available in advance and avoid executing non run-able test-cases.
It implements detection of TCG and KVM only, the rest could be
added later on, when we actually start testing them in qtest.

The responder mr registering with ODP will sent RNR NAK back to
the requester in the face of the page fault.
---------
ibv_poll_cq wc.status=13 RNR retry counter exceeded!
ibv_poll_cq wrid=WRITE RDMA!
---------
ibv_advise_mr(3) helps to make pages present before the actual IO is
conducted so that the responder does page fault as little as possible.

Previously, for the fsdax mem-backend-file, it will register failed with
Operation not supported. In this case, we can try to register it with
On-Demand Paging[1] like what rpma_mr_reg() does on rpma[2].
