2021-06-03spapr: Don't hijack current_machine->boot_orderGreg Kurz
QEMU 6.0 moved all the -boot variables to the machine. Especially, the removal of the boot_order static changed the handling of '-boot once' from: if (boot_once) { qemu_boot_set(boot_once, &error_fatal); qemu_register_reset(restore_boot_order, g_strdup(boot_order)); } to if (current_machine->boot_once) { qemu_boot_set(current_machine->boot_once, &error_fatal); qemu_register_reset(restore_boot_order, g_strdup(current_machine->boot_order)); } This means that we now register as subsequent boot order a copy of current_machine->boot_once that was just set with the previous call to qemu_boot_set(), i.e. we never transition away from the once boot order. It is certainly fragile^Wwrong for the spapr code to hijack a field of the base machine type object like that. The boot order rework simply turned this software boundary violation into an actual bug. Have the spapr code to handle that with its own field in SpaprMachineState. Also kfree() the initial boot device string when "once" was used.

2021-05-26cpu: Rename CPUClass vmsd -> legacy_vmsdPhilippe Mathieu-Daudé
Quoting Peter Maydell [*]: There are two ways to handle migration for a CPU object: (1) like any other device, so it has a dc->vmsd that covers migration for the whole object. As usual for objects that are a subclass of a parent that has state, the first entry in the VMStateDescription field list is VMSTATE_CPU(), which migrates the cpu_common fields, followed by whatever the CPU's own migration fields are. (2) a backwards-compatible mechanism for CPUs that were originally migrated using manual "write fields to the migration stream structures". The on-the-wire migration format for those is based on the 'env' pointer (which isn't a QOM object), and the cpu_common part of the migration data is elsewhere. cpu_exec_realizefn() handles both possibilities: * for type 1, dc->vmsd is set and cc->vmsd is not, so cpu_exec_realizefn() does nothing, and the standard "register dc->vmsd for a device" code does everything needed * for type 2, dc->vmsd is NULL and so we register the vmstate_cpu_common directly to handle the cpu-common fields, and the cc->vmsd to handle the per-CPU stuff You can't change a CPU from one type to the other without breaking migration compatibility, which is why some guest architectures are stuck on the cc->vmsd form. New targets should use dc->vmsd. To avoid new targets to start using type (2), rename cc->vmsd as cc->legacy_vmsd. The correct field to implement is dc->vmsd (the DeviceClass one). See also commit b170fce3dd0 ("cpu: Register VMStateDescription through CPUState") for historic background.

2021-05-26KVM: Dirty ring supportPeter Xu
KVM dirty ring is a new interface to pass over dirty bits from kernel to the userspace. Instead of using a bitmap for each memory region, the dirty ring contains an array of dirtied GPAs to fetch (in the form of offset in slots). For each vcpu there will be one dirty ring that binds to it. kvm_dirty_ring_reap() is the major function to collect dirty rings. It can be called either by a standalone reaper thread that runs in the background, collecting dirty pages for the whole VM. It can also be called directly by any thread that has BQL taken.

2021-05-18vhost-user-blk: Check that num-queues is supported by backendKevin Wolf
Creating a device with a number of queues that isn't supported by the backend is pointless, the device won't work properly and the error messages are rather confusing. Just fail to create the device if num-queues is higher than what the backend supports. Since the relationship between num-queues and the number of virtqueues depends on the specific device, this is an additional value that needs to be initialised by the device. For convenience, allow leaving it 0 if the check should be skipped. This makes sense for vhost-user-net where separate vhost devices are used for the queues and custom initialisation code is needed to perform the check.

2021-05-14hw/smbios: support for type 41 (onboard devices extended information)Vincent Bernat
Type 41 defines the attributes of devices that are onboard. The original intent was to imply the BIOS had some level of control over the enablement of the associated devices. If network devices are present in this table, by default, udev will name the corresponding interfaces enoX, X being the instance number. Without such information, udev will fallback to using the PCI ID and this usually gives ens3 or ens4. This can be a bit annoying as the name of the network card may depend on the order of options and may change if a new PCI device is added earlier on the commande line. Being able to provide SMBIOS type 41 entry ensure the name of the interface won't change and helps the user guess the right name without booting a first time. This can be invoked with: $QEMU -netdev user,id=internet -device virtio-net-pci,mac=50:54:00:00:00:42,netdev=internet,id=internet-dev \ -smbios type=41,designation='Onboard LAN',instance=1,kind=ethernet,pcidev=internet-dev The PCI segment is assumed to be 0. This should hold true for most cases. $ dmidecode -t 41 # dmidecode 3.3 Getting SMBIOS data from sysfs. SMBIOS 2.8 present.
