2023-10-12hw/rdma: Deprecate the pvrdma device and the rdma subsystemThomas Huth1-1/+1
This subsystem is said to be in a bad shape (see e.g. [1], [2] and [3]), and nobody seems to feel responsible to pick up patches for this and send them via a pull request. For example there is a patch for a CVE-worthy bug posted more than half a year ago [4] which has never been merged. Thus let's mark it as deprecated and finally remove it unless somebody steps up and improves the code quality and adds proper regression tests.

2023-10-12MAINTAINERS: Add section for overall sensorsPhilippe Mathieu-Daudé1-0/+6
Sensor devices depend on some bus, not a particular board. While merged for a particular board, sensor devices don't depend on it. They depend on a bus technology, and can be used by any board exposing such bus. In order to help merging sensor patches, when they fall out of a particular board tree, add a section covering overall sensors, to help out with patch review and merge queue handling.

2023-10-06audio: add Apple Sound Chip (ASC) emulationMark Cave-Ayland1-0/+2
The Apple Sound Chip was primarily used by the Macintosh II to generate sound in hardware which was previously handled by the toolbox ROM with software interrupts. Implement both the standard ASC and also the enhanced ASC (EASC) functionality which is used in the Quadra 800. Note that whilst real ASC hardware uses AUDIO_FORMAT_S8, this implementation uses AUDIO_FORMAT_U8 instead because AUDIO_FORMAT_S8 is rarely used and not supported by some audio backends like PulseAudio and DirectSound when played directly with -audiodev out.mixing-engine=off.

This API manages objects (in this iteration, dmabuf fds) that can be shared along different virtio devices, associated to a UUID. The API allows the different devices to add, remove and/or retrieve the objects by simply invoking the public functions that reside in the virtio-dmabuf file.

2023-09-18net: add initial support for AF_XDP network backendIlya Maximets1-0/+4
AF_XDP is a network socket family that allows communication directly with the network device driver in the kernel, bypassing most or all of the kernel networking stack. In the essence, the technology is pretty similar to netmap. But, unlike netmap, AF_XDP is Linux-native and works with any network interfaces without driver modifications. Unlike vhost-based backends (kernel, user, vdpa), AF_XDP doesn't require access to character devices or unix sockets. Only access to the network interface itself is necessary. This patch implements a network backend that communicates with the kernel by creating an AF_XDP socket. A chunk of userspace memory is shared between QEMU and the host kernel. 4 ring buffers (Tx, Rx, Fill and Completion) are placed in that memory along with a pool of memory buffers for the packet data. Data transmission is done by allocating one of the buffers, copying packet data into it and placing the pointer into Tx ring. After transmission, device will return the buffer via Completion ring. On Rx, device will take a buffer form a pre-populated Fill ring, write the packet data into it and place the buffer into Rx ring. AF_XDP network backend takes on the communication with the host kernel and the network interface and forwards packets to/from the peer device in QEMU. Usage example: -device virtio-net-pci,netdev=guest1,mac=00:16:35:AF:AA:5C -netdev af-xdp,ifname=ens6f1np1,id=guest1,mode=native,queues=1 XDP program bridges the socket with a network interface. It can be attached to the interface in 2 different modes: 1. skb - this mode should work for any interface and doesn't require driver support. With a caveat of lower performance. 2. native - this does require support from the driver and allows to bypass skb allocation in the kernel and potentially use zero-copy while getting packets in/out userspace. By default, QEMU will try to use native mode and fall back to skb. Mode can be forced via 'mode' option. To force 'copy' even in native mode, use 'force-copy=on' option. This might be useful if there is some issue with the driver. Option 'queues=N' allows to specify how many device queues should be open. Note that all the queues that are not open are still functional and can receive traffic, but it will not be delivered to QEMU. So, the number of device queues should generally match the QEMU configuration, unless the device is shared with something else and the traffic re-direction to appropriate queues is correctly configured on a device level (e.g. with ethtool -N). 'start-queue=M' option can be used to specify from which queue id QEMU should start configuring 'N' queues. It might also be necessary to use this option with certain NICs, e.g. MLX5 NICs. See the docs for examples. In a general case QEMU will need CAP_NET_ADMIN and CAP_SYS_ADMIN or CAP_BPF capabilities in order to load default XSK/XDP programs to the network interface and configure BPF maps. It is possible, however, to run with no capabilities. For that to work, an external process with enough capabilities will need to pre-load default XSK program, create AF_XDP sockets and pass their file descriptors to QEMU process on startup via 'sock-fds' option. Network backend will need to be configured with 'inhibit=on' to avoid loading of the program. QEMU will need 32 MB of locked memory (RLIMIT_MEMLOCK) per queue or CAP_IPC_LOCK. There are few performance challenges with the current network backends. First is that they do not support IO threads. This means that data path is handled by the main thread in QEMU and may slow down other work or may be slowed down by some other work. This also means that taking advantage of multi-queue is generally not possible today. Another thing is that data path is going through the device emulation code, which is not really optimized for performance. The fastest "frontend" device is virtio-net. But it's not optimized for heavy traffic either, because it expects such use-cases to be handled via some implementation of vhost (user, kernel, vdpa). In practice, we have virtio notifications and rcu lock/unlock on a per-packet basis and not very efficient accesses to the guest memory. Communication channels between backend and frontend devices do not allow passing more than one packet at a time as well. Some of these challenges can be avoided in the future by adding better batching into device emulation or by implementing vhost-af-xdp variant. There are also a few kernel limitations. AF_XDP sockets do not support any kinds of checksum or segmentation offloading. Buffers are limited to a page size (4K), i.e. MTU is limited. Multi-buffer support implementation for AF_XDP is in progress, but not ready yet. Also, transmission in all non-zero-copy modes is synchronous, i.e. done in a syscall. That doesn't allow high packet rates on virtual interfaces. However, keeping in mind all of these challenges, current implementation of the AF_XDP backend shows a decent performance while running on top of a physical NIC with zero-copy support. Test setup: 2 VMs running on 2 physical hosts connected via ConnectX6-Dx card. Network backend is configured to open the NIC directly in native mode. The driver supports zero-copy. NIC is configured to use 1 queue. Inside a VM - iperf3 for basic TCP performance testing and dpdk-testpmd for PPS testing. iperf3 result: TCP stream : 19.1 Gbps dpdk-testpmd (single queue, single CPU core, 64 B packets) results: Tx only : 3.4 Mpps Rx only : 2.0 Mpps L2 FWD Loopback : 1.5 Mpps In skb mode the same setup shows much lower performance, similar to the setup where pair of physical NICs is replaced with veth pair: iperf3 result: TCP stream : 9 Gbps dpdk-testpmd (single queue, single CPU core, 64 B packets) results: Tx only : 1.2 Mpps Rx only : 1.0 Mpps L2 FWD Loopback : 0.7 Mpps Results in skb mode or over the veth are close to results of a tap backend with vhost=on and disabled segmentation offloading bridged with a NIC.

2023-08-31accel: Remove HAX acceleratorPhilippe Mathieu-Daudé1-8/+0
HAX is deprecated since commits 73741fda6c ("MAINTAINERS: Abort HAXM maintenance") and 90c167a1da ("docs/about/deprecated: Mark HAXM in QEMU as deprecated"), released in v8.0.0. Per the latest HAXM release (v7.8 [*]), the latest QEMU supported is v7.2: Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0. The next commit (https://github.com/intel/haxm/commit/da1b8ec072) added: HAXM v7.8.0 is our last release and we will not accept pull requests or respond to issues after this. It became very hard to build and test HAXM. Its previous maintainers made it clear they won't help. It doesn't seem to be a very good use of QEMU maintainers to spend their time in a dead project. Save our time by removing this orphan zombie code.

Let's factor out (un)plug handling, to be reused from arm/virt code. Provide stubs for the case that CONFIG_VIRTIO_MD is not selected because neither virtio-mem nor virtio-pmem is enabled. While this cannot currently happen for x86, it will be possible for arm/virt.
