2023-02-17net: stream: add a new option to automatically reconnectLaurent Vivier1-3/+3
In stream mode, if the server shuts down there is currently no way to reconnect the client to a new server without removing the NIC device and the netdev backend (or to reboot). This patch introduces a reconnect option that specifies a delay to try to reconnect with the same parameters. Add a new test in qtest to test the reconnect option and the connect/disconnect events.

2023-01-08hw/acpi/aml-build: Only generate cluster node in PPTT when specifiedYicong Yang1-0/+3
Currently we'll always generate a cluster node no matter user has specified '-smp clusters=X' or not. Cluster is an optional level and will participant the building of Linux scheduling domains and only appears on a few platforms. It's unncessary to always build it when it cannot reflect the real topology on platforms having no cluster implementation and to avoid affecting the linux scheduling domains in the VM. So only generate the cluster topology in ACPI PPTT when the user has specified it explicitly in -smp. Tested qemu-system-aarch64 with `-smp 8` and linux 6.1-rc1, without this patch: estuary:/sys/devices/system/cpu/cpu0/topology$ cat cluster_* ff # cluster_cpus 0-7 # cluster_cpus_list 56 # cluster_id with this patch: estuary:/sys/devices/system/cpu/cpu0/topology$ cat cluster_* ff # cluster_cpus 0-7 # cluster_cpus_list 36 # cluster_id, with no cluster node kernel will make it to physical package id Acked-by: Michael S.

2022-10-31os-posix: asynchronous teardown for shutdown on LinuxClaudio Imbrenda1-0/+19
This patch adds support for asynchronously tearing down a VM on Linux. When qemu terminates, either naturally or because of a fatal signal, the VM is torn down. If the VM is huge, it can take a considerable amount of time for it to be cleaned up. In case of a protected VM, it might take even longer than a non-protected VM (this is the case on s390x, for example). Some users might want to shut down a VM and restart it immediately, without having to wait. This is especially true if management infrastructure like libvirt is used. This patch implements a simple trick on Linux to allow qemu to return immediately, with the teardown of the VM being performed asynchronously. If the new commandline option -async-teardown is used, a new process is spawned from qemu at startup, using the clone syscall, in such way that it will share its address space with qemu.The new process will have the name "cleanup/<QEMU_PID>". It will wait until qemu terminates completely, and then it will exit itself. This allows qemu to terminate quickly, without having to wait for the whole address space to be torn down. The cleanup process will exit after qemu, so it will be the last user of the address space, and therefore it will take care of the actual teardown. The cleanup process will share the same cgroups as qemu, so both memory usage and cpu time will be accounted properly. If possible, close_range will be used in the cleanup process to close all open file descriptors. If it is not available or if it fails, /proc will be used to determine which file descriptors to close. If the cleanup process is forcefully killed with SIGKILL before the main qemu process has terminated completely, the mechanism is defeated and the teardown will not be asynchronous. This feature can already be used with libvirt by adding the following to the XML domain definition to pass the parameter to qemu directly: <commandline xmlns="http://libvirt.org/schemas/domain/qemu/1.0"> <arg value='-async-teardown'/> </commandline> Signed-off-by: Claudio Imbrenda <imbrenda@linux.ibm.com> Reviewed-by: Murilo Opsfelder Araujo <muriloo@linux.ibm.com> Tested-by: Murilo Opsfelder Araujo <muriloo@linux.ibm.com> Message-Id: <20220812133453.82671-1-imbrenda@linux.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2022-10-28qapi: net: add stream and dgram netdevsLaurent Vivier1-0/+12
Copied from socket netdev file and modified to use SocketAddress to be able to introduce new features like unix socket. "udp" and "mcast" are squashed into dgram netdev, multicast is detected according to the IP address type. "listen" and "connect" modes are managed by stream netdev. An optional parameter "server" defines the mode (off by default) The two new types need to be parsed the modern way with -netdev, because with the traditional way, the "type" field of netdev structure collides with the "type" field of SocketAddress and prevents the correct evaluation of the command line option. Moreover the traditional way doesn't allow to use the same type (SocketAddress) several times with the -netdev option (needed to specify "local" and "remote" addresses). The previous commit paved the way for parsing the modern way, but omitted one detail: how to pick modern vs. traditional, in netdev_is_modern(). We want to pick based on the value of parameter "type". But how to extract it from the option argument? Parsing the option argument, either the modern or the traditional way, extracts it for us, but only if parsing succeeds. If parsing fails, there is no good option. No matter which parser we pick, it'll be the wrong one for some arguments, and the error reporting will be confusing. Fortunately, the traditional parser accepts *anything* when called in a certain way. This maximizes our chance to extract the value of "type", and in turn minimizes the risk of confusing error reporting.

2022-10-11i386: add notify VM exit supportChenyi Qiang1-0/+11
There are cases that malicious virtual machine can cause CPU stuck (due to event windows don't open up), e.g., infinite loop in microcode when nested #AC (CVE-2015-5307). No event window means no event (NMI, SMI and IRQ) can be delivered. It leads the CPU to be unavailable to host or other VMs. Notify VM exit is introduced to mitigate such kind of attacks, which will generate a VM exit if no event window occurs in VM non-root mode for a specified amount of time (notify window). A new KVM capability KVM_CAP_X86_NOTIFY_VMEXIT is exposed to user space so that the user can query the capability and set the expected notify window when creating VMs. The format of the argument when enabling this capability is as follows: Bit 63:32 - notify window specified in qemu command Bit 31:0 - some flags (e.g. KVM_X86_NOTIFY_VMEXIT_ENABLED is set to enable the feature.) Users can configure the feature by a new (x86 only) accel property: qemu -accel kvm,notify-vmexit=run|internal-error|disable,notify-window=n The default option of notify-vmexit is run, which will enable the capability and do nothing if the exit happens. The internal-error option raises a KVM internal error if it happens. The disable option does not enable the capability. The default value of notify-window is 0. It is valid only when notify-vmexit is not disabled. The valid range of notify-window is non-negative. It is even safe to set it to zero since there's an internal hardware threshold to be added to ensure no false positive. Because a notify VM exit may happen with VM_CONTEXT_INVALID set in exit qualification (no cases are anticipated that would set this bit), which means VM context is corrupted. It would be reflected in the flags of KVM_EXIT_NOTIFY exit. If KVM_NOTIFY_CONTEXT_INVALID bit is set, raise a KVM internal error unconditionally.

2022-09-13semihosting: Allow optional use of semihosting from userspacePeter Maydell1-2/+9
Currently our semihosting implementations generally prohibit use of semihosting calls in system emulation from the guest userspace. This is a very long standing behaviour justified originally "to provide some semblance of security" (since code with access to the semihosting ABI can do things like read and write arbitrary files on the host system). However, it is sometimes useful to be able to run trusted guest code which performs semihosting calls from guest userspace, notably for test code. Add a command line suboption to the existing semihosting-config option group so that you can explicitly opt in to semihosting from guest userspace with -semihosting-config userspace=on (There is no equivalent option for the user-mode emulator, because there by definition all code runs in userspace and has access to semihosting already.) This commit adds the infrastructure for the command line option and adds a bool 'is_user' parameter to the function semihosting_userspace_enabled() that target code can use to check whether it should be permitting the semihosting call for userspace. It mechanically makes all the callsites pass 'false', so they continue checking "is semihosting enabled in general". Subsequent commits will make each target that implements semihosting honour the userspace=on option by passing the correct value and removing whatever "don't do this for userspace" checking they were doing by hand.

2022-05-14introduce -audio as a replacement for -soundhwPaolo Bonzini1-27/+24
-audio is used like "-audio pa,model=sb16". It is almost as simple as -soundhw, but it reuses the -audiodev parsing machinery and attaches an audiodev to the newly-created device. The main 'feature' is that it knows about adding the codec device for model=intel-hda, and adding the audiodev to the codec device. In the future, it could be extended to support default models or builtin devices, just like -nic, or even a default backend. For now, keep it simple.

2022-05-13hw/cxl/host: Add support for CXL Fixed Memory Windows.Jonathan Cameron1-0/+38
The concept of these is introduced in [1] in terms of the description the CEDT ACPI table. The principal is more general. Unlike once traffic hits the CXL root bridges, the host system memory address routing is implementation defined and effectively static once observable by standard / generic system software. Each CXL Fixed Memory Windows (CFMW) is a region of PA space which has fixed system dependent routing configured so that accesses can be routed to the CXL devices below a set of target root bridges. The accesses may be interleaved across multiple root bridges. For QEMU we could have fully specified these regions in terms of a base PA + size, but as the absolute address does not matter it is simpler to let individual platforms place the memory regions. ExampleS: -cxl-fixed-memory-window targets.0=cxl.0,size=128G -cxl-fixed-memory-window targets.0=cxl.1,size=128G -cxl-fixed-memory-window targets.0=cxl0,targets.1=cxl.1,size=256G,interleave-granularity=2k Specifies * 2x 128G regions not interleaved across root bridges, one for each of the root bridges with ids cxl.0 and cxl.1 * 256G region interleaved across root bridges with ids cxl.0 and cxl.1 with a 2k interleave granularity. When system software enumerates the devices below a given root bridge it can then decide which CFMW to use. If non interleave is desired (or possible) it can use the appropriate CFMW for the root bridge in question. If there are suitable devices to interleave across the two root bridges then it may use the 3rd CFMS. A number of other designs were considered but the following constraints made it hard to adapt existing QEMU approaches to this particular problem. 1) The size must be known before a specific architecture / board brings up it's PA memory map. We need to set up an appropriate region. 2) Using links to the host bridges provides a clean command line interface but these links cannot be established until command line devices have been added. Hence the two step process used here of first establishing the size, interleave-ways and granularity + caching the ids of the host bridges and then, once available finding the actual host bridges so they can be used later to support interleave decoding.

2022-04-28remove -writeconfigPaolo Bonzini1-6/+2
Like -set and -readconfig, it would not really be too hard to extend -writeconfig to parsing mechanisms other than QemuOpts. However, the uses of -writeconfig are substantially more limited, as it is generally easier to write the configuration by hand in the first place. In addition, -writeconfig does not even try to detect cases where it prints incorrect syntax (for example if values have a quote in them, since qemu_config_parse does not support any kind of escaping. Just remove it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <20220414145721.326866-1-pbonzini@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
