2020-03-11block.c: adding bdrv_co_delete_fileDaniel Henrique Barboza
Using the new 'bdrv_co_delete_file' interface, a pure co_routine function 'bdrv_co_delete_file' inside block.c can can be used in a way similar of the existing bdrv_create_file to to clean up a created file. We're creating a pure co_routine because the only caller of 'bdrv_co_delete_file' will be already in co_routine context, thus there is no need to add all the machinery to check for qemu_in_coroutine() and create a separated co_routine to do the job.

2020-03-11block/block-copy: fix progress calculationVladimir Sementsov-Ogievskiy
Assume we have two regions, A and B, and region B is in-flight now, region A is not yet touched, but it is unallocated and should be skipped. Correspondingly, as progress we have total = A + B current = 0 If we reset unallocated region A and call progress_reset_callback, it will calculate 0 bytes dirty in the bitmap and call job_progress_set_remaining, which will set total = current + 0 = 0 + 0 = 0 So, B bytes are actually removed from total accounting. When job finishes we'll have total = 0 current = B , which doesn't sound good. This is because we didn't considered in-flight bytes, actually when calculating remaining, we should have set (in_flight + dirty_bytes) as remaining, not only dirty_bytes. To fix it, let's refactor progress calculation, moving it to block-copy itself instead of fixing callback. And, of course, track in_flight bytes count. We still have to keep one callback, to maintain backup job bytes_read calculation, but it will go on soon, when we turn the whole backup process into one block_copy call.

2020-03-09aio-posix: remove idle poll handlers to improve scalabilityStefan Hajnoczi
When there are many poll handlers it's likely that some of them are idle most of the time. Remove handlers that haven't had activity recently so that the polling loop scales better for guests with a large number of devices. This feature only takes effect for the Linux io_uring fd monitoring implementation because it is capable of combining fd monitoring with userspace polling. The other implementations can't do that and risk starving fds in favor of poll handlers, so don't try this optimization when they are in use. IOPS improves from 10k to 105k when the guest has 100 virtio-blk-pci,num-queues=32 devices and 1 virtio-blk-pci,num-queues=1 device for rw=randread,iodepth=1,bs=4k,ioengine=libaio on NVMe.

2020-03-09aio-posix: support userspace polling of fd monitoringStefan Hajnoczi
Unlike ppoll(2) and epoll(7), Linux io_uring completions can be polled from userspace. Previously userspace polling was only allowed when all AioHandler's had an ->io_poll() callback. This prevented starvation of fds by userspace pollable handlers. Add the FDMonOps->need_wait() callback that enables userspace polling even when some AioHandlers lack ->io_poll(). For example, it's now possible to do userspace polling when a TCP/IP socket is monitored thanks to Linux io_uring.

2020-03-09aio-posix: add io_uring fd monitoring implementationStefan Hajnoczi
The recent Linux io_uring API has several advantages over ppoll(2) and epoll(2). Details are given in the source code. Add an io_uring implementation and make it the default on Linux. Performance is the same as with epoll(7) but later patches add optimizations that take advantage of io_uring. It is necessary to change how aio_set_fd_handler() deals with deleting AioHandlers since removing monitored file descriptors is asynchronous in io_uring. fdmon_io_uring_remove() marks the AioHandler deleted and aio_set_fd_handler() will let it handle deletion in that case.

The AioHandler *node, bool is_new arguments are more complicated to think about than simply being given AioHandler *old_node, AioHandler *new_node. Furthermore, the new Linux io_uring file descriptor monitoring mechanism added by the new patch requires access to both the old and the new nodes. Make this change now in preparation.

2020-03-09aio-posix: extract ppoll(2) and epoll(7) fd monitoringStefan Hajnoczi
The ppoll(2) and epoll(7) file descriptor monitoring implementations are mixed with the core util/aio-posix.c code. Before adding another implementation for Linux io_uring, extract out the existing ones so there is a clear interface and the core code is simpler. The new interface is AioContext->fdmon_ops, a pointer to a FDMonOps struct. See the patch for details. Semantic changes: 1. ppoll(2) now reflects events from pollfds[] back into AioHandlers while we're still on the clock for adaptive polling. This was already happening for epoll(7), so if it's really an issue then we'll need to fix both in the future. 2. epoll(7)'s fallback to ppoll(2) while external events are disabled was broken when the number of fds exceeded the epoll(7) upgrade threshold. I guess this code path simply wasn't tested and no one noticed the bug. I didn't go out of my way to fix it but the correct code is simpler than preserving the bug. I also took some liberties in removing the unnecessary AioContext->epoll_available (just check AioContext->epollfd != -1 instead) and AioContext->epoll_enabled (it's implicit if our AioContext->fdmon_ops callbacks are being invoked) fields.

2020-03-08pcie_root_port: Add hotplug disabling optionJulia Suvorova
Make hot-plug/hot-unplug on PCIe Root Ports optional to allow libvirt manage it and restrict unplug for the whole machine. This is going to prevent user-initiated unplug in guests (Windows mostly). Hotplug is enabled by default. Usage: -device pcie-root-port,hotplug=off,... If you want to disable hot-unplug on some downstream ports of one switch, disable hot-unplug on PCIe Root Port connected to the upstream port as well as on the selected downstream ports.

2020-03-06monitor: Create QAPIfied monitor_init()Kevin Wolf
This adds a new QAPI-based monitor_init() function. The existing monitor_init_opts() is rewritten to simply put its QemuOpts parameter into a visitor and pass the resulting QAPI object to monitor_init(). This will cause some change in those error messages for the monitor options in the system emulator that are now generated by the visitor rather than explicitly checked in monitor_init_opts().

2020-03-06qemu-storage-daemon: Add --nbd-server optionKevin Wolf
Add a --nbd-server option to qemu-storage-daemon to start the built-in NBD server right away. It maps the arguments for nbd-server-start to the command line, with the exception that it uses SocketAddress instead of SocketAddressLegacy: New interfaces shouldn't use legacy types, and the additional nesting would be nasty on the command line. Example (only with required options): --nbd-server addr.type=inet,addr.host=localhost,addr.port=10809 Signed-off-by: Kevin Wolf <kwolf@redhat.com> Message-Id: <20200224143008.13362-10-kwolf@redhat.com> Acked-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2020-03-06qapi: Flatten object-addKevin Wolf
Mapping object-add to the command line as is doesn't result in nice syntax because of the nesting introduced with 'props'. This becomes nicer and more consistent with device_add and netdev_add when we accept properties for the object on the top level instead. 'props' is still accepted after this patch, but marked as deprecated.
