2024-02-14virtio: split into vhost-user-base and vhost-user-deviceAlex Bennée4-333/+365
Lets keep a cleaner split between the base class and the derived vhost-user-device which we can use for generic vhost-user stubs. This includes an update to introduce the vq_size property so the number of entries in a virtq can be defined.

2024-02-07virtio: Re-enable notifications after drainHanna Czenczek1-0/+42
During drain, we do not care about virtqueue notifications, which is why we remove the handlers on it. When removing those handlers, whether vq notifications are enabled or not depends on whether we were in polling mode or not; if not, they are enabled (by default); if so, they have been disabled by the io_poll_start callback. Because we do not care about those notifications after removing the handlers, this is fine. However, we have to explicitly ensure they are enabled when re-attaching the handlers, so we will resume receiving notifications. We do this in virtio_queue_aio_attach_host_notifier*(). If such a function is called while we are in a polling section, attaching the notifiers will then invoke the io_poll_start callback, re-disabling notifications. Because we will always miss virtqueue updates in the drained section, we also need to poll the virtqueue once after attaching the notifiers.

2024-02-06oslib-posix: initialize backend memory objects in parallelMark Kanda1-2/+2
QEMU initializes preallocated backend memory as the objects are parsed from the command line. This is not optimal in some cases (e.g. memory spanning multiple NUMA nodes) because the memory objects are initialized in series. Allow the initialization to occur in parallel (asynchronously). In order to ensure optimal thread placement, asynchronous initialization requires prealloc context threads to be in use.

This commit was created with scripts/clean-includes: ./scripts/clean-includes --git acpi include/hw/*/*acpi.h hw/*/*acpi.c All .c should include qemu/osdep.h first. The script performs three related cleanups: * Ensure .c files include qemu/osdep.h first. * Including it in a .h is redundant, since the .c already includes it. Drop such inclusions. * Likewise, including headers qemu/osdep.h includes is redundant. Drop these, too.

Commit 8077b8e549 added: DEFINE_PROP_ARRAY("reserved-regions", VirtIOIOMMUPCI, vdev.nb_reserved_regions, vdev.reserved_regions, qdev_prop_reserved_region, ReservedRegion), but forgot to free the 'vdev.reserved_regions' array.

2023-11-13virtio-mem: fix division by zero in virtio_mem_activate_memslots_to_plug()David Hildenbrand1-10/+12
When running with "dynamic-memslots=off", we enter virtio_mem_activate_memslots_to_plug() to return immediately again because "vmem->dynamic_memslots == false". However, the compiler might not optimize out calculating start_idx+end_idx, where we divide by vmem->memslot_size. In such a configuration, the memslot size is 0 and we'll get a division by zero: (qemu) qom-set vmem0 requested-size 3G (qemu) q35.sh: line 38: 622940 Floating point exception(core dumped) The same is true for virtio_mem_deactivate_unplugged_memslots(), however we never really reach that code without a prior virtio_mem_activate_memslots_to_plug() call. Let's fix it by simply calling these functions only with "dynamic-memslots=on". This was found when using a debug build of QEMU.

2023-11-01cpr: relax vhost migration blockersSteve Sistare1-1/+1
vhost blocks migration if logging is not supported to track dirty memory, and vhost-user blocks it if the log cannot be saved to a shm fd. vhost-vdpa blocks migration if both hosts do not support all the device's features using a shadow VQ, for tracking requests and dirty memory. vhost-scsi blocks migration if storage cannot be shared across hosts, or if state cannot be migrated. None of these conditions apply if the old and new qemu processes do not run concurrently, and if new qemu starts on the same host as old, which is the case for cpr. Narrow the scope of these blockers so they only apply to normal mode. They will not block cpr modes when they are added in subsequent patches. No functional change until a new mode is added.

2023-10-31virtio: use defer_call() in virtio_irqfd_notify()Stefan Hajnoczi2-1/+13
virtio-blk and virtio-scsi invoke virtio_irqfd_notify() to send Used Buffer Notifications from an IOThread. This involves an eventfd write(2) syscall. Calling this repeatedly when completing multiple I/O requests in a row is wasteful. Use the defer_call() API to batch together virtio_irqfd_notify() calls made during thread pool (aio=threads), Linux AIO (aio=native), and io_uring (aio=io_uring) completion processing. Behavior is unchanged for emulated devices that do not use defer_call_begin()/defer_call_end() since defer_call() immediately invokes the callback when called outside a defer_call_begin()/defer_call_end() region. fio rw=randread bs=4k iodepth=64 numjobs=8 IOPS increases by ~9% with a single IOThread and 8 vCPUs. iodepth=1 decreases by ~1% but this could be noise. Detailed performance data and configuration specifics are available here: https://gitlab.com/stefanha/virt-playbooks/-/tree/blk_io_plug-irqfd This duplicates the BH that virtio-blk uses for batching. The next commit will remove it.
