2016-09-19Replace qmp-commands.hx by docs/qmp-commands.txtMarc-André Lureau1-4925/+0
The only remaining function of qmp-commands.hx is to let us generate qmp-commands.txt from it. Replace qmp-commands.hx by qmp-commands.txt. We intend to move the documentation into the QAPI schema and generate qapi-commands.txt from it, but not right now.

2016-09-06qmp: add QMP interface "query-cpu-model-baseline"David Hildenbrand1-0/+6
Let's provide a standardized interface to baseline two CPU models, to create a third, compatible one. This is especially helpful when two CPU models are not identical, but a CPU model is required that is guaranteed to run under both configurations, where the original models run. "query-cpu-model-baseline" takes two CPU models and returns a third, compatible model. The result will always be a static CPU model.

2016-09-06qmp: add QMP interface "query-cpu-model-comparison"David Hildenbrand1-0/+6
Let's provide a standardized interface to compare two CPU models. "query-cpu-model-compare" takes two models and returns how they compare in a specific configuration. The result will give guarantees about runnability. E.g. if a CPU model A is a subset of CPU model B, model A is guaranteed to run in configurations where model B runs, but not the other way around (might or might not run). Usually, CPU features or CPU generations are used to calculate the result. If a model is not guaranteed to run in a certain environment (e.g. incompatible), a compatible one can be created by "baselining" both models (follow up patch).

Let's provide a standardized interface to expand CPU models. This interface can be used by tooling to get details about a specific CPU model in a certain configuration, e.g. about the "host" model. To take care of all architectures, two detail levels for an expansion are introduced. Certain architectures might not support all detail levels. While "full" will expand and indicate all relevant properties/features of a CPU model, "static" expands to a static base CPU model, that will never change between QEMU versions and therefore have the same features when used under different compatibility machines.

The idea is simple - backup is "written-once" data. It is written block by block and it is large enough. It would be nice to save storage space and compress it. The patch adds a flag to the qmp/hmp drive-backup command which enables block compression. Compression should be implemented in the format driver to enable this feature. There are some limitations of the format driver to allow compressed writes. We can write data only once. Though for backup this is perfectly fine. These limitations are maintained by the driver and the error will be reported if we are doing something wrong.

2016-03-30arm: qmp: add query-gic-capabilities interfacePeter Xu1-0/+27
This patch add "query-gic-capabilities" but does not implement it. The command is ARM-only. The command will return a list of GICCapability structs that describes all GIC versions that current QEMU and system support. Libvirt is possibly the first consumer of this new command. Before this patch, a libvirt user can successfully configure all kinds of GIC devices for ARM guests, no matter whether current QEMU/kernel supports them. If the specified GIC version/type is not supported, the user will get an ambiguous "QEMU boot failure" error when trying to start the VM. This is not user-friendly. With this patch, libvirt should be able to query which type (and which version) of GIC device is supported. Using this information, libvirt can warn the user during configuration of guests when specified GIC device type is not supported. Or better, we can just list those versions that we support, and filter out the unsupported ones. For example, if we got the query result: {"return": [{"emulated": false, "version": 3, "kernel": true}, {"emulated": true, "version": 2, "kernel": false}]} then it means that we support emulated GIC version 2 using: qemu-system-aarch64 -M virt,accel=tcg,gic-version=2 ... or KVM-accelerated GIC version 3 using: qemu-system-aarch64 -M virt,accel=kvm,gic-version=3 ... If we specify other explicit GIC versions rather than the above, QEMU will not be able to boot. The community is working on a more generic way to query these kinds of information about valid values of machine properties. However, due to the importance of supporting this specific use case, weecided to first implement this ad-hoc one; then when the generic method is ready, we can move on to that one smoothly.

2016-02-22Dump: add qmp command "query-dump"Peter Xu1-1/+26
When dump-guest-memory is requested with detach flag, after its return, user could query its status using "query-dump" command (with no argument). The result contains: - status: current dump status - completed: bytes written in the latest dump - total: bytes to write in the latest dump From completed and total, we could know how much work finished by calculating: 100.0 * completed / total (%) Reviewed-by: Fam Zheng <famz@redhat.com> Signed-off-by: Peter Xu <peterx@redhat.com> Message-Id: <1455772616-8668-10-git-send-email-peterx@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

This modifies the nbd-server-start QMP command so that it is possible to request use of TLS. This is done by adding a new optional parameter "tls-creds" which provides the ID of a previously created QCryptoTLSCreds object instance. TLS is only supported when using an IPv4/IPv6 socket listener. Signed-off-by: Daniel P.

This will start a mirror job from a named device to another named device, its relation with drive-mirror is similar with blockdev-backup to drive-backup. In blockdev-mirror, the target node should be prepared by blockdev-add, which will be responsible for assigning a name to the new node, so we don't have 'node-name' parameter.

2015-12-17cpu: Convert CpuInfo into flat unionEric Blake1-0/+4
The CpuInfo struct is used only by the 'query-cpus' output command, so we are free to modify it by adding fields (clients are already supposed to ignore unknown output fields), or by changing optional members to mandatory, while still keeping QMP wire compatibility with older versions of qemu. When qapi type CpuInfo was originally created for 0.14, we had no notion of a flat union, and instead just listed a bunch of optional fields with documentation about the mutually-exclusive choice of which instruction pointer field(s) would be provided for a given architecture. But now that we have flat unions and introspection, it is better to segregate off which fields will be provided according to the actual architecture. With this in place, we no longer need the fields to be optional, because the choice of the new 'arch' discriminator serves that role. This has an additional benefit: the old all-in-one struct was the only place in the code base that had a case-sensitive naming of members 'pc' vs. 'PC'. Separating these spellings into different branches of the flat union will allow us to add restrictions against future case-insensitive collisions, since that is generally a poor interface practice.

2015-12-11blockdev: Mark {insert, remove}-medium experimentalMax Reitz1-11/+17
While in the long term we want throttling to be its own block filter BDS, in the short term we want it to be part of the BB instead of a BDS; even in the long term we may want legacy throttling to be automatically tied to the BB. blockdev-insert-medium and blockdev-remove-medium do not retain throttling information in the BB (deliberately so). Therefore, using them means tying this information to a BDS, which would break the model described above. (The same applies to other flags such as detect_zeroes.) We probably want to move this information to the BB or its own filter BDS before blockdev-{insert,remove}-medium can be considered completely stable. Therefore, mark these functions experimental for the time being.
