* docs/devel/testing/functional: Add a section about loggingThomas Huth2025-03-191-2/+20

* docs: disambiguate references in qapi-domain.rstJohn Snow2025-03-141-7/+7

* docs/qapi_domain: add namespace support to cross-referencesJohn Snow2025-03-141-4/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does three things: 1. Record the current namespace context in pending_xrefs so it can be used for link resolution later, 2. Pass that recorded namespace context to find_obj() when resolving a reference, and 3. Wildly and completely rewrite find_obj(). cross-reference support is expanded to tolerate the presence or absence of either namespace or module, and to cope with the presence or absence of contextual information for either. References now work like this: 1. If the explicit reference target is recorded in the domain's object registry, we link to that target and stop looking. We do this lookup regardless of how fully qualified the target is, which allows direct references to modules (which don't have a module component to their names) or direct references to definitions that may or may not belong to a namespace or module. 2. If contextual information is available from qapi:namespace or qapi:module directives, try using those components to find a direct match to the implied target name. 3. If both prior lookups fail, generate a series of regular expressions looking for wildcard matches in order from most to least specific. Any explicitly provided components (namespace, module) *must* match exactly, but both contextual and entirely omitted components are allowed to differ from the search result. Note that if more than one result is found, Sphinx will emit a warning (a build error for QEMU) and list all of the candidate references. The practical upshot is that in the large majority of cases, namespace and module information is not required when creating simple `references` to definitions from within the same context -- even when identical definitions exist in other contexts. Even when using simple `references` from elsewhere in the QEMU documentation manual, explicit namespace info is not required if there is only one definition by that name. Disambiguation *will* be required from outside of the QAPI documentation when referencing e.g. block-core definitions, which are shared between QEMU QMP and the QEMU Storage Daemon. In that case, there are two options: A: References can be made partially or fully explicit, e.g. `QMP:block-dirty-bitmap-add` will link to the QEMU version of the definition, while `QSD:block-dirty-bitmap-add` would link to the QSD version. B: If all of the references in a document are intended to go to the same place, you can insert a "qapi:namespace:: QMP" directive to influence the fuzzy-searching for later references.

* docs/qapi-domain: add qapi:namespace directiveJohn Snow2025-03-141-1/+19
| | | | | | | | | | | | | | | | | Add a new directive that marks the beginning of a QAPI "namespace", for example; "QMP", "QGA" or "QSD". This directive will associate all subsequent QAPI directives in a document with the specified namespace. This does not change the visual display of any of the definitions or index entries, but does change the "Fully Qualified Name" inside the QAPI domain's object table. This allows for two different "namespaces" to define entities with otherwise identical names -- which will come in handy for documenting both QEMU QMP and the QEMU Storage Daemon.

* docs/qapi-domain: add :namespace: override optionJohn Snow2025-03-141-0/+2
| | | | | | | | | | | | | | | | | | Akin to the :module: override option, the :namespace: options allows you to forcibly override the contextual namespace associatied with a definition. We don't necessarily actually need this, but I felt compelled to stick close to how the Python domain works that offers context overrides. As of this commit, it is possible to add e.g. ":namespace: QMP" to any QAPI directive to forcibly associate that definition with a given namespace.

Each VFIO device that has multifd device state transfer enabled has one such thread, which is created using migration core API qemu_loadvm_start_load_thread(). Since it's important to finish loading device state transferred via the main migration channel (via save_live_iterate SaveVMHandler) before starting loading the data asynchronously transferred via multifd the thread doing the actual loading of the multifd transferred data is only started from switchover_start SaveVMHandler. switchover_start handler is called when MIG_CMD_SWITCHOVER_START sub-command of QEMU_VM_COMMAND is received via the main migration channel. This sub-command is only sent after all save_live_iterate data have already been posted so it is safe to commence loading of the multifd-transferred device state upon receiving it - loading of save_live_iterate data happens synchronously in the main migration thread (much like the processing of MIG_CMD_SWITCHOVER_START) so by the time MIG_CMD_SWITCHOVER_START is processed all the proceeding data must have already been loaded.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The multifd received data needs to be reassembled since device state packets sent via different multifd channels can arrive out-of-order. Therefore, each VFIO device state packet carries a header indicating its position in the stream. The raw device state data is saved into a VFIOStateBuffer for later in-order loading into the device. The last such VFIO device state packet should have VFIO_DEVICE_STATE_CONFIG_STATE flag set and carry the device config state. Signed-off-by: Maciej S.

* rust: add module to convert between success/-errno and io::ResultPaolo Bonzini2025-02-251-0/+1
| | | | | | | | | | | | | It is a common convention in QEMU to return a positive value in case of success, and a negated errno value in case of error. Unfortunately, using errno portably in Rust is a bit complicated; on Unix the errno values are supported natively by io::Error, but on Windows they are not; so, use the libc crate. This is a set of utility functions that are used by both chardev and block layer bindings. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
