Ricardo Ribalda 9848a76c0b tests/acpi: pc: update golden masters for DSDT
Note: since all we did is replace VarPackageOp with PackageOP,
and both are represented by Package() in ASL, the AML is
different but ASL is the same.

Ricardo Ribalda 7916bb5431 hw/i386/acpi-build: return a non-var package from _PRT()
Windows XP seems to have issues when _PRT() returns a variable package.
We know in advance the size, so we can return a fixed package instead.

Vladimir Sementsov-Ogievskiy 9e4cc917e0 qdev-monitor: add option to report GenericError from find_device_state
Here we just prepare for the following patch, making possible to report
GenericError as recommended.

This patch doesn't aim to prevent further use of DeviceNotFound by
future interfaces:

 - find_device_state() is used in blk_by_qdev_id() and qmp_get_blk()
   functions, which may lead to spread of DeviceNotFound anyway
 - also, nothing prevent simply copy-pasting find_device_state() calls
   with false argument

Jonathan Cameron ea3f0ebc1a hw/pcie: Provide a utility function for control of EP / SW USP link
Whilst similar to existing PCIESlot link configuration a few registers
need to be set differently so that the downstream device presents
a 'configured' state that is then used to 'train' the upstream port
on the link.  Basically that means setting the status register to
reflect it succeeding in training up to target settings.

Jonathan Cameron a82fe82916 hw/acpi: Generic Port Affinity Structure support
These are very similar to the recently added Generic Initiators
but instead of representing an initiator of memory traffic they
represent an edge point beyond which may lie either targets or
initiators.  Here we add these ports such that they may
be targets of hmat_lb records to describe the latency and
bandwidth from host side initiators to the port.  A discoverable
mechanism such as UEFI CDAT read from CXL devices and switches
is used to discover the remainder of the path, and the OS can build
up full latency and bandwidth numbers as need for work and data
placement decisions.

Thomas Huth bc9da794cc hw/s390x: Re-enable the pci-bridge device on s390x
Commit e779e5c05a ("hw/pci-bridge: Add a Kconfig switch for the
normal PCI bridge") added a config switch for the pci-bridge, so
that the device is not included in the s390x target anymore (since
the pci-bridge is not really useful on s390x).

However, it seems like libvirt is still adding pci-bridge devices
automatically to the guests' XML definitions (when adding a PCI
device to a non-zero PCI bus), so these guests are now broken due
to the missing pci-bridge in the QEMU binary.

To avoid disruption of the users, let's re-enable the pci-bridge
device on s390x for the time being.

results in a clear error:

 "Cirrus CI Cloud only allows ghcr.io/cirruslabs/macos-runner:sonoma image ..."

If you still try to run a Sequoia image, it gets automatically "upgraded"
to Sonoma instead. So the macos-15 job in the QEMU CI now does not
