40 hourshw/arm/virt: Allow user-creatable SMMUv3 dev instantiationShameer Kolothum1-0/+1
Allow cold-plugging of an SMMUv3 device on the virt machine when no global (legacy) SMMUv3 is present or when a virtio-iommu is specified. This user-created SMMUv3 device is tied to a specific PCI bus provided by the user, so ensure the IOMMU ops are configured accordingly. Due to current limitations in QEMU’s device tree support, specifically its inability to properly present pxb-pcie based root complexes and their devices, the device tree support for the new SMMUv3 device is limited to cases where it is attached to the default pcie.0 root complex.

40 hourshw/pci: Introduce pci_setup_iommu_per_bus() for per-bus IOMMU ops retrievalShameer Kolothum2-0/+3
Currently, pci_setup_iommu() registers IOMMU ops for a given PCIBus. However, when retrieving IOMMU ops for a device using pci_device_get_iommu_bus_devfn(), the function checks the parent_dev and fetches IOMMU ops from the parent device, even if the current bus does not have any associated IOMMU ops. This behavior works for now because QEMU's IOMMU implementations are globally scoped, and host bridges rely on the bypass_iommu property to skip IOMMU translation when needed. However, this model will break with the soon to be introduced arm-smmuv3 device, which allows users to associate the IOMMU with a specific PCIe root complex (e.g., the default pcie.0 or a pxb-pcie root complex). For example, consider the following setup with multiple root complexes: -device arm-smmuv3,primary-bus=pcie.0,id=smmuv3.0 \ ... -device pxb-pcie,id=pcie.1,bus_nr=8,bus=pcie.0 \ -device pcie-root-port,id=pcie.port1,bus=pcie.1 \ -device virtio-net-pci,bus=pcie.port1 In Qemu, pxb-pcie acts as a special root complex whose parent is effectively the default root complex(pcie.0). Hence, though pcie.1 has no associated SMMUv3 as per above, pci_device_get_iommu_bus_devfn() will incorrectly return the IOMMU ops from pcie.0 due to the fallback via parent_dev. To fix this, introduce a new helper pci_setup_iommu_per_bus() that explicitly sets the new iommu_per_bus field in the PCIBus structure. This helper will be used in a subsequent patch that adds support for the new arm-smmuv3 device. Update pci_device_get_iommu_bus_devfn() to use iommu_per_bus when determining the correct IOMMU ops, ensuring accurate behavior for per-bus IOMMUs.

Introduce a new struct AcpiIortSMMUv3Dev to hold all the information required for SMMUv3 IORT node and use that for populating the node. The current machine wide SMMUv3 is named as legacy SMMUv3 as we will soon add support for user-creatable SMMUv3 devices. These changes will be useful to have common code paths when we add that support.

We only allow default PCIe Root Complex(pcie.0) or pxb-pcie based extra root complexes to be associated with SMMU. Although this change does not affect functionality at present, it is required when we add support for user-creatable SMMUv3 devices in future patches. Note: Added a specific check to identify pxb-pcie to avoid matching pxb-cxl host bridges, which are also of type PCI_HOST_BRIDGE. This restriction can be relaxed once support for CXL devices on arm/virt is added and validated with SMMUv3.

In many places where we want to initialize an IRQ we are in the init/realize of some other QOM object; if we have a variant of this function that calls object_initialize_child() then the IRQ will be automatically cleaned up when its parent object is destroyed, and we don't need to remember to manually free it.

2025-08-30hw/intc/arm_gicv3_kvm: preserve pending interrupts during cprSteve Sistare1-0/+3
Close a race condition that causes cpr-transfer to lose VFIO interrupts on ARM. CPR stops VCPUs but does not disable VFIO interrupts, which may continue to arrive throughout the transition to new QEMU. CPR calls kvm_irqchip_remove_irqfd_notifier_gsi in old QEMU to force future interrupts to the producer eventfd, where they are preserved. Old QEMU then destroys the old KVM instance. However, interrupts may already be pending in KVM state. To preserve them, call ioctl KVM_DEV_ARM_VGIC_SAVE_PENDING_TABLES to flush them to guest RAM, where they will be picked up when the new KVM+VCPU instance is created.

2025-08-09vfio/pci: preserve pending interruptsSteve Sistare1-0/+6
cpr-transfer may lose a VFIO interrupt because the KVM instance is destroyed and recreated. If an interrupt arrives in the middle, it is dropped. To fix, stop pending new interrupts during cpr save, and pick up the pieces. In more detail: Stop the VCPUs. Call kvm_irqchip_remove_irqfd_notifier_gsi --> KVM_IRQFD to deassign the irqfd gsi that routes interrupts directly to the VCPU and KVM. After this call, interrupts fall back to the kernel vfio_msihandler, which writes to QEMU's kvm_interrupt eventfd. CPR already preserves that eventfd. When the route is re-established in new QEMU, the kernel tests the eventfd and injects an interrupt to KVM if necessary. Deassign INTx in a similar manner. For both MSI and INTx, remove the eventfd handler so old QEMU does not consume an event. If an interrupt was already pended to KVM prior to the completion of kvm_irqchip_remove_irqfd_notifier_gsi, it will be recovered by the subsequent call to cpu_synchronize_all_states, which pulls KVM interrupt state to userland prior to saving it in vmstate.

2025-07-22crypto: implement workaround for GNUTLS thread safety problemsDaniel P. Berrangé1-0/+14
When TLS 1.3 is negotiated on a TLS session, GNUTLS will perform automatic rekeying of the session after 16 million records. This is done for all algorithms except CHACHA20_POLY1305 which does not require rekeying. Unfortunately the rekeying breaks GNUTLS' promise that it is safe to use a gnutls_session_t object concurrently from multiple threads if they are exclusively calling gnutls_record_send/recv. This patch implements a workaround for QEMU that adds a mutex lock around any gnutls_record_send/recv call to serialize execution within GNUTLS code. When GNUTLS calls into the push/pull functions we can release the lock so the OS level I/O calls can at least have some parallelism. The big downside of this is that the actual encryption/decryption code is fully serialized, which will halve performance of that cipher operations if two threads are contending. The workaround is not enabled by default, since most use of GNUTLS in QEMU does not tickle the problem, only non-multifd migration with a return path open is affected. Fortunately the migration code also won't trigger the halving of performance, since only the outbound channel diretion needs to sustain high data rates, the inbound direction is low volume.

2025-07-21host-utils: Drop workaround for buggy Apple Clang __builtin_subcll()Peter Maydell2-14/+1
In commit b0438861efe ("host-utils: Avoid using __builtin_subcll on buggy versions of Apple Clang") we added a workaround for a bug in Apple Clang 14 where its __builtin_subcll() implementation was wrong. This bug was only present in Apple Clang 14, not in upstream clang, and is not present in Apple Clang versions 15 and newer. Since commit 4e035201 we have required at least Apple Clang 15, so we no longer build with the buggy versions. We can therefore drop the workaround. This is effectively a revert of b0438861efe. This should not be backported to stable branches, which may still need to support Apple Clang 14.

2025-07-21ppc/xive2: implement NVP context save restore for POOL ringNicholas Piggin1-0/+1
In preparation to implement POOL context push, add support for POOL NVP context save/restore. The NVP p bit is defined in the spec as follows: If TRUE, the CPPR of a Pool VP in the NVP is updated during store of the context with the CPPR of the Hard context it was running under. It's not clear whether non-pool VPs always or never get CPPR updated. Before this patch, OS contexts always save CPPR, so we will assume that is the behaviour.

2025-07-21ppc/xive: tctx signaling registers reworkNicholas Piggin1-1/+25
The tctx "signaling" registers (PIPR, CPPR, NSR) raise an interrupt on the target CPU thread. The POOL and PHYS rings both raise hypervisor interrupts, so they both share one set of signaling registers in the PHYS ring. The PHYS NSR register contains a field that indicates which ring has presented the interrupt being signaled to the CPU. This sharing results in all the "alt_regs" throughout the code. alt_regs is not very descriptive, and worse is that the name is used for conversions in both directions, i.e., to find the presenting ring from the signaling ring, and the signaling ring from the presenting ring. Instead of alt_regs, use the names sig_regs and sig_ring, and regs and ring for the presenting ring being worked on. Add a helper function to get the sign_regs, and add some asserts to ensure the POOL regs are never used to signal interrupts.
