2022-01-27qapi: generate trace events by defaultVladimir Sementsov-Ogievskiy
We don't generate trace events for tests/ and qga/ because that it is not simple and not necessary. We have corresponding comments in both tests/meson.build and qga/meson.build. Still to not miss possible future qapi code generation call, and not to forget to enable trace events generation, let's enable it by default. So, turn option --gen-trace into opposite --no-trace-events and use new option only in tests/ and qga/ where we already have good comments why we don't generate trace events code. Note that this commit enables trace-events generation for qapi-gen.py call from tests/qapi-schema/meson.build and storage-daemon/meson.build. Still, both are kind of noop: tests/qapi-schema/ doesn't seem to generate any QMP command code and no .trace-events files anyway, storage-daemon/ uses common QMP command implementations and just generate empty .trace-events Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Message-Id: <20220126161130.3240892-8-vsementsov@virtuozzo.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>

2022-01-14block: drop BLK_PERM_GRAPH_MODVladimir Sementsov-Ogievskiy
First, this permission never protected a node from being changed, as generic child-replacing functions don't check it. Second, it's a strange thing: it presents a permission of parent node to change its child. But generally, children are replaced by different mechanisms, like jobs or qmp commands, not by nodes. Graph-mod permission is hard to understand. All other permissions describe operations which done by parent node on its child: read, write, resize. Graph modification operations are something completely different. The only place where BLK_PERM_GRAPH_MOD is used as "perm" (not shared perm) is mirror_start_job, for s->target. Still modern code should use bdrv_freeze_backing_chain() to protect from graph modification, if we don't do it somewhere it may be considered as a bug. So, it's a bit risky to drop GRAPH_MOD, and analyzing of possible loss of protection is hard. But one day we should do it, let's do it now. One more bit of information is that locking the corresponding byte in file-posix doesn't make sense at all.

2022-01-14softmmu: fix device deletion events with -device JSON syntaxDaniel P. Berrangé
The -device JSON syntax impl leaks a reference on the created DeviceState instance. As a result when you hot-unplug the device, the device_finalize method won't be called and thus it will fail to emit the required DEVICE_DELETED event. A 'json-cli' feature was previously added against the 'device_add' QMP command QAPI schema to indicated to mgmt apps that -device supported JSON syntax. Given the hotplug bug that feature flag is not usable for its purpose, so we add a new 'json-cli-hotplug' feature to indicate the -device supports JSON without breaking hotplug.

2021-12-31hw/core/machine: Introduce CPU cluster topology supportYanan Wang
The new Cluster-Aware Scheduling support has landed in Linux 5.16, which has been proved to benefit the scheduling performance (e.g. load balance and wake_affine strategy) on both x86_64 and AArch64. So now in Linux 5.16 we have four-level arch-neutral CPU topology definition like below and a new scheduler level for clusters. struct cpu_topology { int thread_id; int core_id; int cluster_id; int package_id; int llc_id; cpumask_t thread_sibling; cpumask_t core_sibling; cpumask_t cluster_sibling; cpumask_t llc_sibling; } A cluster generally means a group of CPU cores which share L2 cache or other mid-level resources, and it is the shared resources that is used to improve scheduler's behavior. From the point of view of the size range, it's between CPU die and CPU core. For example, on some ARM64 Kunpeng servers, we have 6 clusters in each NUMA node, and 4 CPU cores in each cluster. The 4 CPU cores share a separate L2 cache and a L3 cache tag, which brings cache affinity advantage. In virtualization, on the Hosts which have pClusters (physical clusters), if we can design a vCPU topology with cluster level for guest kernel and have a dedicated vCPU pinning. A Cluster-Aware Guest kernel can also make use of the cache affinity of CPU clusters to gain similar scheduling performance. This patch adds infrastructure for CPU cluster level topology configuration and parsing, so that the user can specify cluster parameter if their machines support it.

2021-12-21ui: add a D-Bus display backendMarc-André Lureau
The "dbus" display backend exports the QEMU consoles and other UI-related interfaces over D-Bus. By default, the connection is established on the session bus, but you can specify a different bus with the "addr" option. The backend takes the "org.qemu" service name, while still allowing further instances to queue on the same name (so you can lookup all the available instances too). It accepts any number of clients at this point, although this is expected to evolve with options to restrict clients, or only accept p2p via fd passing. The interface is intentionally very close to the internal QEMU API, and can be introspected or interacted with busctl/dfeet etc: $ ./qemu-system-x86_64 -name MyVM -display dbus $ busctl --user introspect org.qemu /org/qemu/Display1/Console_0 org.qemu.Display1.Console interface - - - .RegisterListener method h - - .SetUIInfo method qqiiuu - - .DeviceAddress property s "pci/0000/01.0" emits-change .Head property u 0 emits-change .Height property u 480 emits-change .Label property s "VGA" emits-change .Type property s "Graphic" emits-change .Width property u 640 emits-change [...] See the interfaces XML source file and Sphinx docs for the generated API documentations.

2021-11-09qapi: deprecate drive-backupVladimir Sementsov-Ogievskiy
Modern way is using blockdev-add + blockdev-backup, which provides a lot more control on how target is opened. As example of drive-backup problems consider the following: User of drive-backup expects that target will be opened in the same cache and aio mode as source. Corresponding logic is in drive_backup_prepare(), where we take bs->open_flags of source. It works rather bad if source was added by blockdev-add. Assume source is qcow2 image. On blockdev-add we should specify aio and cache options for file child of qcow2 node. What happens next: drive_backup_prepare() looks at bs->open_flags of qcow2 source node. But there no BDRV_O_NOCAHE neither BDRV_O_NATIVE_AIO: BDRV_O_NOCAHE is places in bs->file->bs->open_flags, and BDRV_O_NATIVE_AIO is nowhere, as file-posix parse options and simply set s->use_linux_aio. The documentation is updated in a minimal way, so that drive-backup is noted only as a deprecated command, and blockdev-backup used in most of places.

2021-11-08docs: remove non-reference uses of single backticksJohn Snow
The single backtick markup in ReST is the "default role". Currently, Sphinx's default role is called "content". Sphinx suggests you can use the "Any" role instead to turn any single-backtick enclosed item into a cross-reference. This is useful for things like autodoc for Python docstrings, where it's often nicer to reference other types with `foo` instead of the more laborious :py:meth:`foo`. It's also useful in multi-domain cases to easily reference definitions from other Sphinx domains, such as referencing C code definitions from outside of kerneldoc comments. Before we do that, though, we'll need to turn all existing usages of the "content" role to inline verbatim markup wherever it does not correctly resolve into a cross-refernece by using double backticks instead.

2021-11-02monitor: introduce HumanReadableText and HMP supportDaniel P. Berrangé
This provides a foundation on which to convert simple HMP commands to use QMP. The QMP implementation will generate formatted text targeted for human consumption, returning it in the HumanReadableText data type. The HMP command handler will simply print out the formatted string within the HumanReadableText data type. Since this will be an entirely formulaic action in the case of HMP commands taking no arguments, a custom command handler is provided. Thus instead of registering a 'cmd' callback for the HMP command, a 'cmd_info_hrt' callback is provided, which will simply be a pointer to the QMP implementation.

2021-11-02file-posix: add `aio-max-batch` optionStefano Garzarella
Commit d7ddd0a161 ("linux-aio: limit the batch size using `aio-max-batch` parameter") added a way to limit the batch size of Linux AIO backend for the entire AIO context. The same AIO context can be shared by multiple devices, so latency-sensitive devices may want to limit the batch size even more to avoid increasing latency. For this reason we add the `aio-max-batch` option to the file backend, which will be used by the next commits to limit the size of batches including requests generated by this device.

2021-11-02vmdk: allow specification of tools versionThomas Weißschuh
VMDK files support an attribute that represents the version of the guest tools that are installed on the disk. This attribute is used by vSphere before a machine has been started to determine if the VM has the guest tools installed. This is important when configuring "Operating system customizations" in vSphere, as it checks for the presence of the guest tools before allowing those customizations. Thus when the VM has not yet booted normally it would be impossible to customize it, therefore preventing a customized first-boot. The attribute should not hurt on disks that do not have the guest tools installed and indeed the VMware tools also unconditionally add this attribute.
