2023-03-13qmp: 'add_client' actually expects socketsMarc-André Lureau1-0/+7
Whether it is SPICE, VNC, D-Bus, or the socket chardev, they all actually expect a socket kind or will fail in different ways at runtime. Throw an error early if the given 'add_client' fd is not a socket, and close it to avoid leaks. This allows to replace the close() call with a more correct & portable closesocket() version. (this will allow importing sockets on Windows with a specialized command in the following patch, while keeping the remaining monitor associated sockets/add_client code & usage untouched) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Acked-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20230306122751.2355515-6-marcandre.lureau@redhat.com>

2022-10-07jobs: group together API calls under the same job lockEmanuele Giuseppe Esposito1-2/+5
Now that the API offers also _locked() functions, take advantage of it and give also the caller control to take the lock and call _locked functions. This makes sense especially when we have for loops, because it makes no sense to have: for(job = job_next(); ...) where each job_next() takes the lock internally. Instead we want JOB_LOCK_GUARD(); for(job = job_next_locked(); ...) In addition, protect also direct field accesses, by either creating a new critical section or widening the existing ones. Note: at this stage, job_{lock/unlock} and job lock guard macros are *nop*.

2022-06-14qmp: add filtering of statistics by namePaolo Bonzini1-1/+6
Allow retrieving only a subset of statistics. This can be useful for example in order to plot a subset of the statistics many times a second: KVM publishes ~40 statistics for each vCPU on x86; retrieving and serializing all of them would be useless. Another use will be in HMP in the following patch; implementing the filter in the backend is easy enough that it was deemed okay to make this a public interface. Example: { "execute": "query-stats", "arguments": { "target": "vcpu", "vcpus": [ "/machine/unattached/device[2]", "/machine/unattached/device[4]" ], "providers": [ { "provider": "kvm", "names": [ "l1d_flush", "exits" ] } } } { "return": { "vcpus": [ { "path": "/machine/unattached/device[2]" "providers": [ { "provider": "kvm", "stats": [ { "name": "l1d_flush", "value": 41213 }, { "name": "exits", "value": 74291 } ] } ] }, { "path": "/machine/unattached/device[4]" "providers": [ { "provider": "kvm", "stats": [ { "name": "l1d_flush", "value": 16132 }, { "name": "exits", "value": 57922 } ] } ] } ] } } Extracted from a patch by Mark Kanda.

Allow retrieving the statistics from a specific provider only. This can be used in the future by HMP commands such as "info sync-profile" or "info profile". The next patch also adds filter-by-provider capabilities to the HMP equivalent of query-stats, "info stats". Example: { "execute": "query-stats", "arguments": { "target": "vm", "providers": [ { "provider": "kvm" } ] } } The QAPI is a bit more verbose than just a list of StatsProvider, so that it can be subsequently extended with filtering of statistics by name. If a provider is specified more than once in the filter, each request will be included separately in the output. Extracted from a patch by Mark Kanda.

2022-06-14qmp: Support for querying statsMark Kanda1-0/+95
Gathering statistics is important for development, for monitoring and for performance measurement. There are tools such as kvm_stat that do this and they rely on the _user_ knowing the interesting data points rather than the tool (which can treat them as opaque). The commands introduced in this commit introduce QMP support for querying stats; the goal is to take the capabilities of these tools and making them available throughout the whole virtualization stack, so that one can observe, monitor and measure virtual machines without having shell access + root on the host that runs them. query-stats returns a list of all stats per target type (only VM and vCPU to start); future commits add extra options for specifying stat names, vCPU qom paths, and providers. All these are used by the HMP command "info stats". Because of the development usecases around statistics, a good HMP interface is important. query-stats-schemas returns a list of stats included in each target type, with an option for specifying the provider. The concepts in the schema are based on the KVM binary stats' own introspection data, just translated to QAPI. There are two reasons to have a separate schema that is not tied to the QAPI schema. The first is the contents of the schemas: the new introspection data provides different information than the QAPI data, namely unit of measurement, how the numbers are gathered and change (peak/instant/cumulative/histogram), and histogram bucket sizes. There's really no reason to have this kind of metadata in the QAPI introspection schema (except possibly for the unit of measure, but there's a very weak justification). Another reason is the dynamicity of the schema. The QAPI introspection data is very much static; and while QOM is somewhat more dynamic, generally we consider that to be a bug rather than a feature these days. On the other hand, the statistics that are exposed by QEMU might be passed through from another source, such as KVM, and the disadvantages of manually updating the QAPI schema for outweight the benefits from vetting the statistics and filtering out anything that seems "too unstable". Running old QEMU with new kernel is a supported usecase; if old QEMU cannot expose statistics from a new kernel, or if a kernel developer needs to change QEMU before gathering new info from the new kernel, then that is a poor user interface. The framework provides a method to register callbacks for these QMP commands. Most of the work in fact is done by the callbacks, and a large majority of this patch is new QAPI structs and commands. Examples (with KVM stats): - Query all VM stats: { "execute": "query-stats", "arguments" : { "target": "vm" } } { "return": [ { "provider": "kvm", "stats": [ { "name": "max_mmu_page_hash_collisions", "value": 0 }, { "name": "max_mmu_rmap_size", "value": 0 }, { "name": "nx_lpage_splits", "value": 148 }, ... ] }, { "provider": "xyz", "stats": [ ... ] } ] } - Query all vCPU stats: { "execute": "query-stats", "arguments" : { "target": "vcpu" } } { "return": [ { "provider": "kvm", "qom_path": "/machine/unattached/device[0]" "stats": [ { "name": "guest_mode", "value": 0 }, { "name": "directed_yield_successful", "value": 0 }, { "name": "directed_yield_attempted", "value": 106 }, ... ] }, { "provider": "kvm", "qom_path": "/machine/unattached/device[1]" "stats": [ { "name": "guest_mode", "value": 0 }, { "name": "directed_yield_successful", "value": 0 }, { "name": "directed_yield_attempted", "value": 106 }, ... ] }, ] } - Retrieve the schemas: { "execute": "query-stats-schemas" } { "return": [ { "provider": "kvm", "target": "vcpu", "stats": [ { "name": "guest_mode", "unit": "none", "base": 10, "exponent": 0, "type": "instant" }, { "name": "directed_yield_successful", "unit": "none", "base": 10, "exponent": 0, "type": "cumulative" }, ... ] }, { "provider": "kvm", "target": "vm", "stats": [ { "name": "max_mmu_page_hash_collisions", "unit": "none", "base": 10, "exponent": 0, "type": "peak" }, ... ] }, { "provider": "xyz", "target": "vm", "stats": [ ... ] } ] } Signed-off-by: Mark Kanda <mark.kanda@oracle.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2021-12-21ui/dbus: add p2p=on/off optionMarc-André Lureau1-0/+13
Add an option to use direct connections instead of via the bus. Clients are accepted with QMP add_client. This allows to provide the D-Bus display without a bus. It also simplifies the testing setup (some CI have issues to setup a D-Bus bus in a container).

2021-11-02qapi: introduce x-query-irq QMP commandDaniel P. Berrangé1-0/+44
This is a counterpart to the HMP "info irq" command. It is being added with an "x-" prefix because this QMP command is intended as an adhoc debugging tool and will thus not be modelled in QAPI as fully structured data, nor will it have long term guaranteed stability. The existing HMP command is rewritten to call the QMP command. Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>

2021-08-26monitor: Use accel_find("kvm") instead of kvm_available()Peter Maydell1-1/+1
The kvm_available() function reports whether KVM support was compiled into the QEMU binary; it returns the value of the CONFIG_KVM define. The only place in the codebase where we use this function is in qmp_query_kvm(). Now that accelerators are based on QOM classes we can instead use accel_find("kvm") and remove the kvm_available() function.

2021-02-04monitor/qmp-cmds.c: Don't include ui/vnc.hPeter Maydell1-1/+1
The qmp-cmds.c file currently includes ui/vnc.h, which (being located in the ui/ directory rather than include) is really supposed to be for use only by the ui subsystem. In fact the function prototypes we need (vnc_display_password(), etc) are all declared in include/ui/console.h, so we can switch to including that instead. (ui/vnc.h includes include/ui/console.h, so this change strictly reduces the quantity of headers qmp-cmds.c pulls in.)
