2019-10-22qapi: Allow introspecting fix for savevm's cooperation with blockdevPeter Krempa
'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.

2019-10-22qapi: Add feature flags to commandsPeter Krempa
Similarly to features for struct types introduce the feature flags also for commands. This will allow notifying management layers of fixes and compatible changes in the behaviour of a command which may not be detectable any other way. The changes were heavily inspired by commit 6a8c0b51025.

2019-10-18audio: add mixing-engine option (documentation)Kővágó, Zoltán
This will allow us to disable mixeng when we use a decent backend. 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. The ideal solution would be to port as much as possible to gstreamer, but this is currently out of scope: https://wiki.qemu.org/Internships/ProjectIdeas/AudioGStreamer Signed-off-by: Kővágó, Zoltán <DirtY.iCE.hu@gmail.com> Message-id: 5765186a7aadd51a72bc7d3e804307f0ee8a34ce.1570996490.git.DirtY.iCE.hu@gmail.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2019-10-10block/backup: use backup-top instead of write notifiersVladimir Sementsov-Ogievskiy
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.

2019-09-28qapi: Clean up member name case checkingMarkus Armbruster
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.

2019-08-16block/backup: support bitmap sync modes for non-bitmap backupsJohn Snow
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.

2019-08-16block/backup: add 'always' bitmap sync policyJohn Snow
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.

2019-07-05machine: show if CLI option '-numa node,mem' is supported in QAPI schemaIgor Mammedov
Legacy '-numa node,mem' option has a number of issues and mgmt often defaults to it. Unfortunately it's no possible to replace it with an alternative '-numa memdev' without breaking migration compatibility. What's possible though is to deprecate it, keeping option working with old machine types only. In order to help users to find out if being deprecated CLI option '-numa node,mem' is still supported by particular machine type, add new "numa-mem-supported" property to output of query-machines. "numa-mem-supported" is set to 'true' for machines that currently support NUMA, but it will be flipped to 'false' later on, once deprecation period expires and kept 'true' only for old machine types that used to support the legacy option so it won't break existing configuration that are using it.

2019-07-02virtio-pmem: add virtio devicePankaj Gupta
This is the implementation of virtio-pmem device. Support will require machine changes for the architectures that will support it, so it will not yet be compiled. It can be unlocked with VIRTIO_PMEM_SUPPORTED per machine and disabled globally via VIRTIO_PMEM. We cannot use the "addr" property as that is already used e.g. for virtio-pci/pci devices. And we will have e.g. virtio-pmem-pci as a proxy. So we have to choose a different one (unfortunately). "memaddr" it is. That name should ideally be used by all other virtio-* based memory devices in the future. -device virtio-pmem-pci,id=p0,bus=bux0,addr=0x01,memaddr=0x1000000...

2019-07-02net/announce: Add optional IDDr. David Alan Gilbert
Previously there was a single instance of the timer used by monitor triggered announces, that's OK, but when combined with the previous change that lets you have announces for subsets of interfaces it's a bit restrictive if you want to do different things to different interfaces. Add an 'id' field to the announce, and maintain a list of the timers based on id. This allows you to for example: a) Start an announce going on interface eth0 for a long time b) Start an announce going on interface eth1 for a long time c) Kill the announce on eth0 while leaving eth1 going.

2019-07-02net/announce: Allow optional list of interfacesDr. David Alan Gilbert
Allow the caller to restrict the set of interfaces that announces are sent on. The default is still to send on all interfaces. e.g. { "execute": "announce-self", "arguments": { "initial": 50, "max": 550, "rounds": 5, "step": 50, "interfaces": ["vn2", "vn1"] } } This doesn't affect the behaviour of migraiton announcments. Note: There's still only one timer for the qmp command, so that performing an 'announce-self' on one list of interfaces followed by another 'announce-self' on another list will stop the announces on the existing set.
