2025-07-14net: Add save_acked_features callback to vhost_netLaurent Vivier3-16/+4
This commit introduces a save_acked_features function pointer to vhost_net and converts the vhost_net function into a generic dispatcher. The vhost-user backend provides the callback, making its function static. With this change, no other module has a direct dependency on the vhost-user implementation. This cleanup allows for the complete removal of the net/vhost-user.h header file. Signed-off-by: Laurent Vivier <lvivier@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2025-07-14net: Add get_acked_features callback to VhostNetOptionsLaurent Vivier2-2/+3
This patch continues the effort to decouple the generic vhost layer from specific network backend implementations. Previously, the vhost_net initialization code contained a hardcoded check for the vhost-user client type to retrieve its acked features by calling vhost_user_get_acked_features(). This exposed an internal vhost-user function in a public header and coupled the two modules. The vhost-user backend is updated to provide a callback, and its getter function is now static. The call site in vhost_net.c is simplified to use the new generic helper, removing the type check and the direct dependency.

2025-07-14net: Consolidate vhost feature bits into vhost_net structureLaurent Vivier3-2/+2
Previously, the vhost_net_get_feature_bits() function in hw/net/vhost_net.c used a large switch statement to determine the appropriate feature bits based on the NetClientDriver type. This created unnecessary coupling between the generic vhost layer and specific network backends (like TAP, vhost-user, and vhost-vdpa). This patch moves the definition of vhost feature bits directly into the vhost_net structure for each relevant network client.

2025-07-14net: Add get_vhost_net callback to NetClientInfoLaurent Vivier4-6/+2
The get_vhost_net() function previously contained a large switch statement to find the VHostNetState pointer based on the net client's type. This created a tight coupling, requiring the generic vhost layer to be aware of every specific backend that supported vhost, such as tap, vhost-user, and vhost-vdpa. This approach is not scalable and requires modifying a central function for any new backend. It also forced each backend to expose its internal getter function in a public header file. This patch refactors the logic by introducing a new get_vhost_net function pointer to the NetClientInfo struct. The central get_vhost_net() function is now a simple, generic dispatcher that invokes the callback provided by the net client. Each backend now implements its own private getter and registers it in its NetClientInfo. Signed-off-by: Laurent Vivier <lvivier@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2025-07-14vhost_net: Rename vhost_set_vring_enable() for clarityLaurent Vivier1-1/+1
This is a cosmetic change with no functional impact. The function vhost_set_vring_enable() is specific to vhost_net and is used outside of vhost_net.c (specifically, in hw/net/virtio-net.c). To prevent confusion with other similarly named vhost functions, such as the one found in cryptodev-vhost.c, it has been renamed to vhost_net_set_vring_enable(). This clarifies that the function belongs to the vhost_net module. Signed-off-by: Laurent Vivier <lvivier@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2025-07-14net: Define net_client_set_link()Laurent Vivier1-0/+1
The code to set the link status is currently located in qmp_set_link(). This function identifies the device by name, searches for the corresponding NetClientState, and then updates the link status. In some parts of the code, such as vhost-user.c, the NetClientState are already available. Calling qmp_set_link() from these locations leads to a redundant search for the clients. This patch refactors the logic by introducing a new function, net_client_set_link(), which accepts a NetClientState array directly. qmp_set_link() is simplified to be a wrapper that performs the client search and then calls the new function. The vhost-user implementation is updated to use net_client_set_link() directly, thereby eliminating the unnecessary client lookup.

2025-07-14virtio-net: Add queues for RSS during migrationAkihiko Odaki1-2/+8
virtio_net_pre_load_queues() inspects vdev->guest_features to tell if VIRTIO_NET_F_RSS or VIRTIO_NET_F_MQ is enabled to infer the required number of queues. This works for VIRTIO_NET_F_MQ but it doesn't for VIRTIO_NET_F_RSS because only the lowest 32 bits of vdev->guest_features is set at the point and VIRTIO_NET_F_RSS uses bit 60 while VIRTIO_NET_F_MQ uses bit 22. Instead of inferring the required number of queues from vdev->guest_features, use the number loaded from the vm state. This change also has a nice side effect to remove a duplicate peer queue pair change by circumventing virtio_net_set_multiqueue(). Also update the comment in include/hw/virtio/virtio.h to prevent an implementation of pre_load_queues() from refering to any fields being loaded during migration by accident in the future.

2025-07-12sev: Provide sev_features flags from IGVM VMSA to KVM_SEV_INIT2Roy Hopkins1-1/+4
IGVM files can contain an initial VMSA that should be applied to each vcpu as part of the initial guest state. The sev_features flags are provided as part of the VMSA structure. However, KVM only allows sev_features to be set during initialization and not as the guest is being prepared for launch. This patch queries KVM for the supported set of sev_features flags and processes the VP context entries in the IGVM file during kvm_init to determine any sev_features flags set in the IGVM file. These are then provided in the call to KVM_SEV_INIT2 to ensure the guest state matches that specified in the IGVM file. The igvm process() function is modified to allow a partial processing of the file during initialization, with only the IGVM_VHT_VP_CONTEXT fields being processed. This means the function is called twice, firstly to extract the sev_features then secondly to actually configure the guest.

save_complete_precopy_thread Recent patch [1] renames the save_live_complete_precopy handler to save_complete, as the machine is not live in most cases when this handler is executed. The same is true also for save_live_complete_precopy_thread, therefore this patch removes the "live" keyword from the handler itself and related types to keep the naming unified. In contrast to save_complete, this handler is only executed at the end of precopy, therefore the "precopy" keyword is retained.

2025-07-08hw/arm/virt: Basic CXL enablement on pci_expander_bridge instances pxb-cxlJonathan Cameron1-0/+4
Code based on i386/pc enablement. The memory layout places space for 16 host bridge register regions after the GIC_REDIST2 in the extended memmap. This is a hole in the current map so adding them here has no impact on placement of other memory regions (tested with enough CPUs for GIC_REDIST2 to be in use.) The high memory map is GiB aligned so the hole is there whatever the size of memory or device_memory below this point. The CFMWs are placed above the extended memmap. Note the existing variable highest_gpa is the highest GPA that has been allocated at a particular point in setting up the memory map. Whilst this caused some confusion in review there are existing comments explaining this so nothing is added. The cxl_devices_state.host_mr provides a small space in which to place the individual host bridge register regions for whatever host bridges are allocated via -device pxb-cxl on the command line. The existing dynamic sysbus infrastructure is not reused because pxb-cxl is a PCI device not a sysbus one but these registers are directly in the main memory map, not the PCI address space. Only create the CEDT table if cxl=on set for the machine. Default to off.

2025-07-08hw/cxl: Make the CXL fixed memory windows devices.Jonathan Cameron2-2/+7
Previously these somewhat device like structures were tracked using a list in the CXLState in each machine. This is proving restrictive in a few cases where we need to iterate through these without being aware of the machine type. Just make them sysbus devices. Restrict them to not user created as they need to be visible to early stages of machine init given effects on the memory map. This change both simplifies state tracking and enables features needed for performance optimization and hotness tracking by making it possible to retrieve the fixed memory window on actions elsewhere in the topology. In some cases the ordering of the Fixed Memory Windows matters. For those utility functions provide a GSList sorted by the window index. This ensures that we get consistency across: - ordering in the command line - ordering of the host PA ranges - ordering of ACPI CEDT structures describing the CFMWS. Other aspects don't have this constraint. For those direct iteration of the underlying hash structures is fine. In the setup path for the memory map in pc_memory_init() split the operations into two calls. The first, cxl_fmws_set_mmemap(), loops over fixed memory windows in order and assigns their addresses. The second, cxl_fmws_update_mmio() actually sets up the mmio for each window. This is obviously less efficient than a single loop but this split design is needed to put the logic in two different places in the arm64 support and it is not a hot enough path to justify an x86 only implementation.

2025-07-04accel: Expose and register generic_handle_interrupt()Philippe Mathieu-Daudé1-0/+3
In order to dispatch over AccelOpsClass::handle_interrupt(), we need it always defined, not calling a hidden handler under the hood. Make AccelOpsClass::handle_interrupt() mandatory. Expose generic_handle_interrupt() prototype and register it for each accelerator.
