2024-07-05tracepoints: move physmem trace pointsAlex Bennée
They don't need to be in the global trace-events file and can have a local trace header. Also add address_space_map tracepoint for tracking mapping behaviour.

2019-09-25exec: Adjust notdirty tracingRichard Henderson
The memory_region_tb_read tracepoint is unreachable, since notdirty is supposed to apply only to writes. The memory_region_tb_write tracepoint is mis-named, because notdirty is not only used for TB invalidation. It is also used for e.g. VGA RAM updates and migration. Replace memory_region_tb_write with memory_notdirty_write_access, and place it in memory_notdirty_write_prepare where it can catch all of the instances.

2018-03-19qmp: support out-of-band (oob) executionPeter Xu
Having "allow-oob":true for a command does not mean that this command will always be run in out-of-band mode. The out-of-band quick path will only be executed if we specify the extra "run-oob" flag when sending the QMP request: { "execute": "command-that-allows-oob", "arguments": { ... }, "control": { "run-oob": true } } The "control" key is introduced to store this extra flag. "control" field is used to store arguments that are shared by all the commands, rather than command specific arguments. Let "run-oob" be the first. Note that in the patch I exported qmp_dispatch_check_obj() to be used to check the request earlier, and at the same time allowed "id" field to be there since actually we always allow that.

This patches allows QMP monitors to be suspended/resumed. One thing to mention is that for QMPs that are using IOThreads, we need an explicit kick for the IOThread in case it is sleeping. Meanwhile, we need to take special care on non-interactive HMPs. Currently only gdbserver is using that. For these monitors, we still don't allow suspend/resume operations. Since at it, add traces for the operations.

This is a limitation in current SystemTap releases.

2017-06-13monitor: resurrect handle_qmp_command trace eventStefan Hajnoczi
Commit 104fc3027960dd2aa9d310936a6cb201c60e1088 ("qmp: Drop duplicated QMP command object checks") removed the call to trace_handle_qmp_command() while eliminating code duplication. This patch brings the trace event back so QEMU-internal trace events can be correlated with the QMP commands that caused them.

2017-06-06kvm: irqchip: trace changes on msi add/removePeter Xu
It'll be nice to know which virq belongs to which device/vector when adding msi routes, so adding two more parameters for the add trace. Meanwhile, releasing virq has no tracing before. Add one for it.

2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake
Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

2017-03-05qmp: Drop duplicated QMP command object checksMarkus Armbruster
qmp_check_input_obj() duplicates qmp_dispatch_check_obj(), except the latter screws up an error message. handle_qmp_command() runs first the former, then the latter via qmp_dispatch(), masking the screwup. qemu-ga also masks the screwup, because it also duplicates checks, just differently. qmp_check_input_obj() exists because handle_qmp_command() needs to examine the command before dispatching it. The previous commit got rid of this need, except for a tracepoint, and a bit of "id" code that relies on qdict not being null. Fix up the error message in qmp_dispatch_check_obj(), drop qmp_check_input_obj() and the tracepoint. Protect the "id" code with a conditional.

2017-02-21block: move AioContext, QEMUTimer, main-loop to libqemuutilPaolo Bonzini
AioContext is fairly self contained, the only dependency is QEMUTimer but that in turn doesn't need anything else. So move them out of block-obj-y to avoid introducing a dependency from io/ to block-obj-y. main-loop and its dependency iohandler also need to be moved, because later in this series io/ will call iohandler_get_aio_context.
