s390x: express dependencies with Kconfig Instead of hard-coding all config switches in the config file default-configs/s390x-softmmu.mak, let's use the new Kconfig files to express the necessary dependencies: The S390_CCW_VIRTIO config switch for the "s390-ccw-virtio" machine now selects all non-optional devices. And since we already have the VIRTIO_PCI and VIRTIO_MMIO config switches for the other two virtio transports, this patch also introduces a new config switch VIRTIO_CCW for the third, s390x-specific virtio transport, so that all three virtio transports are now handled in the same way.

virtio-mem: Paravirtualized memory hot(un)plug This is the very basic/initial version of virtio-mem. An introduction to virtio-mem can be found in the Linux kernel driver [1]. While it can be used in the current state for hotplug of a smaller amount of memory, it will heavily benefit from resizeable memory regions in the future. Each virtio-mem device manages a memory region (provided via a memory backend). After requested by the hypervisor ("requested-size"), the guest can try to plug/unplug blocks of memory within that region, in order to reach the requested size. Initially, and after a reboot, all memory is unplugged (except in special cases - reboot during postcopy). The guest may only try to plug/unplug blocks of memory within the usable region size. The usable region size is a little bigger than the requested size, to give the device driver some flexibility. The usable region size will only grow, except on reboots or when all memory is requested to get unplugged. The guest can never plug more memory than requested. Unplugged memory will get zapped/discarded, similar to in a balloon device. The block size is variable, however, it is always chosen in a way such that THP splits are avoided (e.g., 2MB). The state of each block (plugged/unplugged) is tracked in a bitmap. As virtio-mem devices (e.g., virtio-mem-pci) will be memory devices, we now expose "VirtioMEMDeviceInfo" via "query-memory-devices". -------------------------------------------------------------------------- There are two important follow-up items that are in the works: 1. Resizeable memory regions: Use resizeable allocations/RAM blocks to grow/shrink along with the usable region size. This avoids creating initially very big VMAs, RAM blocks, and KVM slots. 2. Protection of unplugged memory: Make sure the gust cannot actually make use of unplugged memory. Other follow-up items that are in the works: 1. Exclude unplugged memory during migration (via precopy notifier). 2. Handle remapping of memory. 3. Support for other architectures. -------------------------------------------------------------------------- Example usage (virtio-mem-pci is introduced in follow-up patches): Start QEMU with two virtio-mem devices (one per NUMA node): $ qemu-system-x86_64 -m 4G,maxmem=20G \ -smp sockets=2,cores=2 \ -numa node,nodeid=0,cpus=0-1 -numa node,nodeid=1,cpus=2-3 \ [...] -object memory-backend-ram,id=mem0,size=8G \ -device virtio-mem-pci,id=vm0,memdev=mem0,node=0,requested-size=0M \ -object memory-backend-ram,id=mem1,size=8G \ -device virtio-mem-pci,id=vm1,memdev=mem1,node=1,requested-size=1G Query the configuration: (qemu) info memory-devices Memory device [virtio-mem]: "vm0" memaddr: 0x140000000 node: 0 requested-size: 0 size: 0 max-size: 8589934592 block-size: 2097152 memdev: /objects/mem0 Memory device [virtio-mem]: "vm1" memaddr: 0x340000000 node: 1 requested-size: 1073741824 size: 1073741824 max-size: 8589934592 block-size: 2097152 memdev: /objects/mem1 Add some memory to node 0: (qemu) qom-set vm0 requested-size 500M Remove some memory from node 1: (qemu) qom-set vm1 requested-size 200M Query the configuration again: (qemu) info memory-devices Memory device [virtio-mem]: "vm0" memaddr: 0x140000000 node: 0 requested-size: 524288000 size: 524288000 max-size: 8589934592 block-size: 2097152 memdev: /objects/mem0 Memory device [virtio-mem]: "vm1" memaddr: 0x340000000 node: 1 requested-size: 209715200 size: 209715200 max-size: 8589934592 block-size: 2097152 memdev: /objects/mem1 [1] https://lkml.kernel.org/r/20200311171422.10484-1-david@redhat.com Cc: "Michael S.

build: move vhost-vsock configuration to Kconfig vhost-vsock and vhost-user-vsock are two devices of their own; it should be possible to enable/disable them with --without-default-devices, not --without-default-features. Compute their default value in Kconfig to obtain the more intuitive behavior. Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

vhost-user-rng: Add vhost-user-rng implementation Introduce a random number generator (RNG) backend that communicates with a vhost-user server to retrieve entropy. That way other VMM that comply with the vhost user protocl can use the same vhost-user daemon without having to write yet another RNG driver.
