The Data Object Exchange implementation of CXL Coherent Device Attribute Table (CDAT). This implementation is referring to "Coherent Device Attribute Table Specification, Rev. 1.03, July. 2022" and "Compute Express Link Specification, Rev. 3.0, July. 2022" This patch adds core support that will be shared by both end-points and switch port emulation.

The CDAT can be specified in two ways. One is to add ",cdat=<filename>" in "-device cxl-type3"'s command option. The file is required to provide the whole CDAT table in binary mode. The other is to use the default that provides some 'reasonable' numbers based on type of memory and size. The DOE capability supporting CDAT is added to hw/mem/cxl_type3.c with capability offset 0x190. The config read/write to this capability range can be generated in the OS to request the CDAT data.

… bus In theory the virtio-iommu-pci could be plugged anywhere in the PCIe topology and as long as the dt/acpi info are properly built this should work. However at the moment we fail to do that because the virtio-iommu-pci BDF is not computed at plug time and in that case vms->virtio_iommu_bdf gets an incorrect value. For instance if the virtio-iommu-pci is plugged onto a pcie root port and the virtio-iommu protects a virtio-block-pci device the guest does not boot. So let's do not pretend we do support this case and fail the initialize() if we detect the virtio-iommu-pci is plugged anywhere else than on the root bus. Anyway this ability is not needed.

PCI devices support vq reset. Based on this function, the driver can adjust the size of the ring, and quickly recycle the buffer in the ring. The migration of the virtio devices will not happen during a reset operation. This is becuase the global iothread lock is held. Migration thread also needs the lock. As a result, when migration of virtio devices starts, the 'reset' status of VirtIOPCIQueue will always be 0. Thus, we do not need to add it in vmstate_virtio_pci_modern_queue_state.

Support queue_enable in vhost-kernel scenario. It can be called when a vq reset operation has been performed and the vq is restared. It should be noted that we can restart the vq when the vhost has already started. When launching a new vhost device, the vhost is not started and all vqs are not initalized until VIRTIO_PCI_COMMON_STATUS is written. Thus, we should use vhost_started to differentiate the two cases: vq reset and device start. Currently it only supports vhost-kernel.

vhost backend sends host notification for every VQ. If backend creates
VQs in parallel, the VHOST_USER_SLAVE_VRING_HOST_NOTIFIER_MSG may
arrive to QEMU in different order than incremental queue index order.
For example VQ 1's message arrive earlier than VQ 0's:
After alloc VhostUserHostNotifier for VQ 1. GPtrArray becomes
[ nil, VQ1 pointer ]
After alloc VhostUserHostNotifier for VQ 0. GPtrArray becomes
[ VQ0 pointer, nil, VQ1 pointer ]
This is wrong. fetch_notifier will return NULL for VQ 1 in
vhost_user_get_vring_base, causes host notifier miss removal(leak).
The fix is to remove current element from GPtrArray, make the right
position for element to insert.

However, modules are reused between all architectures so CONFIG_ACPI is on. For those architectures, dummy stub function definitions help to resolve symbols. This change uses more of these and so it adds a couple of dummy stub definitions so that symbols for those can be resolved.

…umeration generate AML PCI-ISA bridges that are built in PIIX/Q35 are building its own AML using AcpiDevAmlIf interface. Now build_append_pci_bus_devices() gained AcpiDevAmlIf interface support to get AML of devices atached to PCI slots. So drop ad-hoc build_q35_isa_bridge()/build_piix4_isa_bridge() and let PCI bus enumeration to include PCI-ISA bridge AML when it's enumerated by build_append_pci_bus_devices(). AML change is mostly contextual, which moves whole ISA hierarchy directly under PCI host bridge instead of it being described as separate \SB.PCI0.ISA block. Note: If bus/slot that hosts ISA bridge has BSEL set, it will gain new ASUN and _DMS entries (i.e. acpi-index support, but it should not cause any functional change and that is fine from PCI Firmware spec point of view), potentially it's possible to suppress that by adding a flag to PCIDevice but I don't see a reason to do that yet, I'd rather treat bridge just as any other PCI device if it's possible.

The SET ADDRESS SPACE CONTROL FAST instruction is not privileged, it can be used from problem space, too. Just the switching to the home address space is privileged and should still generate a privilege exception. This bug is e.g. causing programs like Java that use the "getcpu" vdso kernel function to crash (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=990417#26 ). While we're at it, also check if DAT is not enabled. In that case the instruction is supposed to generate a special operation exception.
