| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds proper support for float samples in mixeng by adding a new audio format for it. Limitations: only native endianness is supported. None of the virtual sound cards support float samples (it looks like most of them only support 8 and 16 bit, only hda supports 32 bit), it is only used for the audio backends (i.e. host side).

|/ | | | | | | | | | | | | | | | | Sometimes it is useful to be able to add a node to the block graph that takes or unshare a certain set of permissions for debugging purposes. This patch adds this capability to blkdebug. (Note that you cannot make blkdebug release or share permissions that it needs to take or cannot share, because this might result in assertion failures in the block layer. But if the blkdebug node has no parents, it will not take any permissions and share everything by default, so you can then freely choose what permissions to take and share.)

| | | | | | | | | | | | | | | | | | | | | | | | | Add support for the query-cpu-model-expansion QMP command to Arm. We do this selectively, only exposing CPU properties which represent optional CPU features which the user may want to enable/disable. Additionally we restrict the list of queryable cpu models to 'max', 'host', or the current type when KVM is in use. And, finally, we only implement expansion type 'full', as Arm does not yet have a "base" CPU type. More details and example queries are described in a new document (docs/arm-cpu-features.rst). Note, certainly more features may be added to the list of advertised features, e.g. 'vfp' and 'neon'. The only requirement is that we can detect invalid configurations and emit failures at QMP query time. For 'vfp' and 'neon' this will require some refactoring to share a validation function between the QMP query and the CPU realize functions.

It will transition into ACTIVE once all devices were succesfully unplugged from the guest. So if a guest doesn't respond or takes long to honor the unplug request the user will see the migration state 'wait-unplug'. In the migration thread we query failover devices if they're are still pending the guest unplug. When all are unplugged the migration continues.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a command's 'data' is an object, its doc comment describes the arguments defined there. When 'data' names a type, the doc comment does not describe arguments. Instead, the doc generator inserts a pointer to the named type. An event's doc comment works the same. We don't actually check doc comments for commands and events. Instead, QAPISchema._def_command() forwards the doc comment to the implicit argument type, where it gets checked. Works because the check only cares for the implicit argument type's members. Not only is this needlessly hard to understand, it actually falls apart in two cases: * When 'data' is empty, there is nothing to forward to, and the doc comment remains unchecked. Demonstrated by test doc-bad-event-arg. * When 'data' names a type, we can't forward, as the type has its own doc comment. The command or event's doc comment remains unchecked. Demonstrated by test doc-bad-boxed-command-arg. The forwarding goes back to commit 069fb5b250 "qapi: Prepare for requiring more complete documentation", put to use in commit 816a57cd6e "qapi: Fix detection of bogus member documentation". That fix was incomplete. To fix this, make QAPISchemaCommand and QAPISchemaEvent check doc comments, and drop the forwarding of doc comments to implicit argument types.

| | | | | | | | | | | | | | | | | | | | | | | 'savevm' was buggy as it considered all monitor-owned block device nodes for snapshot. With the introduction of -blockdev, the common usage made all nodes including protocol and backing file nodes be monitor-owned and thus considered for snapshot. This is a problem since the 'file' protocol nodes can't have internal snapshots and it does not make sense to take snapshot of nodes representing backing files. This was fixed by commit 05f4aced658a02b02. Clients need to be able to detect whether this fix is present. Since savevm does not have an QMP alternative, add the feature for the 'human-monitor-command' backdoor which is used to call this command in modern use.

Disabling mixeng have a few advantages: * we no longer convert the audio output from one format to another, when the underlying audio system would just convert it to a third format. We no longer convert, only the underlying system, when needed. * the underlying system probably has better resampling and sample format converting methods anyway... * we may support formats that the mixeng currently does not support (S24 or float samples, more than two channels) * when using an audio server (like pulseaudio) different sound card outputs will show up as separate streams, even if we use only one backend Disadvantages: * audio capturing no longer works (wavcapture, and vnc audio extension) * some backends only support a single playback stream or very picky about the audio format. In this case we can't disable mixeng. Originally thw two main use cases of the disabled option was: using unsupported audio formats (5.1 and 7.1 audio) and having different pulseaudio streams per audio frontend. Since we can have multiple -audiodevs, the latter is not that important, so currently you only need this option if you want to use 5.1 or 7.1 audio (implemented in a later patch), otherwise it's probably better to stick to the old and tried mixeng, since it's less picky about the backends.

* block/backup: use backup-top instead of write notifiersVladimir Sementsov-Ogievskiy2019-10-101-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drop write notifiers and use filter node instead. = Changes = 1. Add filter-node-name argument for backup qmp api. We have to do it in this commit, as 257 needs to be fixed. 2. There are no more write notifiers here, so is_write_notifier parameter is dropped from block-copy paths. 3. To sync with in-flight requests at job finish we now have drained removing of the filter, we don't need rw-lock. 4. Block-copy is now using BdrvChildren instead of BlockBackends 5. As backup-top owns these children, we also move block-copy state into backup-top's ownership. = Iotest changes = 56: op-blocker doesn't shoot now, as we set it on source, but then check on filter, when trying to start second backup. To keep the test we instead can catch another collision: both jobs will get 'drive0' job-id, as job-id parameter is unspecified. To prevent interleaving with file-posix locks (as they are dependent on config) let's use another target for second backup. Also, it's obvious now that we'd like to drop this op-blocker at all and add a test-case for two backups from one node (to different destinations) actually works. But not in these series. 141: Output changed: prepatch, "Node is in use" comes from bdrv_has_blk check inside qmp_blockdev_del. But we've dropped block-copy blk objects, so no more blk objects on source bs (job blk is on backup-top filter bs). New message is from op-blocker, which is the next check in qmp_blockdev_add. 257: The test wants to emulate guest write during backup. They should go to filter node, not to original source node, of course. Therefore we need to specify filter node name and use it.

* qapi: Clean up member name case checkingMarkus Armbruster2019-09-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | QAPISchemaMember.check_clash() checks for member names that map to the same c_name(). Takes care of rejecting duplicate names. It also checks a naming rule: no uppercase in member names. That's a rather odd place to do it. Enforcing naming rules is check_name_str()'s job. qapi-code-gen.txt specifies the name case rule applies to the name as it appears in the schema. check_clash() checks c_name(name) instead. No difference, as c_name() leaves alone case, but unclean. Move the name case check into check_name_str(), less the c_name(). New argument @permit_upper suppresses it. Pass permit_upper=True for definitions (which are not members), and when the member's owner is whitelisted with pragma name-case-whitelist. Bonus: name-case-whitelist now applies to a union's inline base, too. Update qapi/qapi-schema.json pragma to whitelist union CpuInfo instead of CpuInfo's implicit base type's name q_obj_CpuInfo-base.

* block/backup: support bitmap sync modes for non-bitmap backupsJohn Snow2019-08-171-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | Accept bitmaps and sync policies for the other backup modes. This allows us to do things like create a bitmap synced to a full backup without a transaction, or start a resumable backup process. Some combinations don't make sense, though: - NEVER policy combined with any non-BITMAP mode doesn't do anything, because the bitmap isn't used for input or output. It's harmless, but is almost certainly never what the user wanted. - sync=NONE is more questionable. It can't use on-success because this job never completes with success anyway, and the resulting artifact of 'always' is suspect: because we start with a full bitmap and only copy out segments that get written to, the final output bitmap will always be ... a fully set bitmap. Maybe there's contexts in which bitmaps make sense for sync=none, but not without more severe changes to the current job, and omitting it here doesn't prevent us from adding it later.

| | | | | | | | | | | | | | | | | | | This adds an "always" policy for bitmap synchronization. Regardless of if the job succeeds or fails, the bitmap is *always* synchronized. This means that for backups that fail part-way through, the bitmap retains a record of which sectors need to be copied out to accomplish a new backup using the old, partial result. In effect, this allows us to "resume" a failed backup; however the new backup will be from the new point in time, so it isn't a "resume" as much as it is an "incremental retry." This can be useful in the case of extremely large backups that fail considerably through the operation and we'd like to not waste the work that was already performed.
