2024-05-16vfio/migration: Don't emit STOP_COPY VFIO migration QAPI event twiceAvihai Horon
When migrating a VFIO device that supports pre-copy, it is transitioned to STOP_COPY twice: once in vfio_vmstate_change() and second time in vfio_save_complete_precopy(). The second transition is harmless, as it's a STOP_COPY->STOP_COPY no-op transition. However, with the newly added VFIO migration QAPI event, the STOP_COPY event is undesirably emitted twice. Prevent this by returning early in vfio_migration_set_state() if new_state is the same as current device state. Note that the STOP_COPY transition in vfio_save_complete_precopy() is essential for VFIO devices that don't support pre-copy, for migrating an already stopped guest and for snapshots.

2024-05-16vfio/migration: Emit VFIO migration QAPI eventAvihai Horon
Emit VFIO migration QAPI event when a VFIO device changes its migration state. This can be used by management applications to get updates on the current state of the VFIO device for their own purposes. A new per VFIO device capability, "migration-events", is added so events can be enabled only for the required devices. It is disabled by default.

2024-05-16vfio/pci: migration: Skip config space check for Vendor Specific Information ↵Vinayak Kale
in VSC during restore/load In case of migration, during restore operation, qemu checks config space of the pci device with the config space in the migration stream captured during save operation. In case of config space data mismatch, restore operation is failed. config space check is done in function get_pci_config_device(). By default VSC (vendor-specific-capability) in config space is checked. Due to qemu's config space check for VSC, live migration is broken across NVIDIA vGPU devices in situation where source and destination host driver is different. In this situation, Vendor Specific Information in VSC varies on the destination to ensure vGPU feature capabilities exposed to the guest driver are compatible with destination host. If a vfio-pci device is migration capable and vfio-pci vendor driver is OK with volatile Vendor Specific Info in VSC then qemu should exempt config space check for Vendor Specific Info. It is vendor driver's responsibility to ensure that VSC is consistent across migration. Here consistency could mean that VSC format should be same on source and destination, however actual Vendor Specific Info may not be byte-to-byte identical. This patch skips the check for Vendor Specific Information in VSC for VFIO-PCI device by clearing pdev->cmask[] offsets. Config space check is still enforced for 3 byte VSC header. If cmask[] is not set for an offset, then qemu skips config space check for that offset. VSC check is skipped for machine types >= 9.1. The check would be enforced on older machine types (<= 9.0).

2024-05-09hw/loongarch: Refine default numa id calculationBibo Mao
With numa_test test case, there is subcase named test_def_cpu_split(), there are 8 sockets and 2 numa nodes. Here is command line: "-machine smp.cpus=8,smp.sockets=8 -numa node,memdev=ram -numa node" The required result is: node 0 cpus: 0 2 4 6 node 1 cpus: 1 3 5 7 Test case numa_test fails on LoongArch, since the actual result is: node 0 cpus: 0 1 2 3 node 1 cpus: 4 5 6 7 It will be better if all the cpus in one socket share the same numa node. Here socket id is used to calculate numa id in function virt_get_default_cpu_node_id().

2024-05-09hw/intc/loongson_ipi: Implement IOCSR address space for MIPSJiaxun Yang
Implement IOCSR address space get functions for MIPS/Loongson CPUs. For MIPS/Loongson without IOCSR (i.e. Loongson-3A1000), get_cpu_iocsr_as will return as null, and send_ipi_data will fail with MEMTX_DECODE_ERROR, which matches expected behavior on hardware.
