* monitor: fix dangling CPU pointerGreg Kurz2017-10-301-5/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a CPU selected with the "cpu" command is hot-unplugged then "info cpus" causes QEMU to exit: (qemu) device_del cpu1 (qemu) info cpus qemu:qemu_cpu_kick_thread: No such process This happens because "cpu" stores the pointer to the selected CPU into the monitor structure. When the CPU is hot-unplugged, we end up with a dangling pointer. The "info cpus" command then does: hmp_info_cpus() monitor_get_cpu_index() mon_get_cpu() cpu_synchronize_state() <--- called with dangling pointer This could cause a QEMU crash as well. This patch switches the monitor to store the QOM path instead of a pointer to the current CPU. The path is then resolved when needed. If the resolution fails, we assume that the CPU was removed and the path is resetted to the default (ie, path of first_cpu).

| | | | | | | | | | | | | | | | | | | | The info registers command in the qemu monitor is used to dump register values. Currently this command uses the monitor cpu (which can be set by the user) as the cpu for whose registers will be dumped. Sometimes it is useful to see the registers for all cpus and currently this requires setting the monitor cpu and the re-running the command for each cpu in the system. I would be nice if there was an easier way to do this. Add the "-a" option to the info registers command to dump the register values for all cpus.

* qmp: Drop duplicated QMP command object checksMarkus Armbruster2017-03-051-68/+6Star
| | | | | | | | | | | | | | | | | | | | | | 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.

* qmp: Clean up how we enforce capability negotiationMarkus Armbruster2017-03-051-34/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To enforce capability negotiation before normal operation, handle_qmp_command() inspects every command before it's handed off to qmp_dispatch(). This is a bit of a layering violation, and results in duplicated code. Before capability negotiation (!cur_mon->in_command_mode), we fail commands other than "qmp_capabilities". This is what enforces capability negotiation. Afterwards, we fail command "qmp_capabilities". Clean this up as follows. The obvious place to fail a command is the command itself, so move the "afterwards" check to qmp_qmp_capabilities(). We do the "before" check in every other command, but that would be bothersome. Instead, start with an alternate list of commands that contains only "qmp_capabilities". Switch to the full list in qmp_qmp_capabilities(). Additionally, replace the generic human-readable error message for CommandNotFound by one that reminds the user to run qmp_capabilities. Without that, we'd regress commit 2d5a834.

* qmp: Dumb down how we run QMP command registrationMarkus Armbruster2017-03-051-5/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way we get QMP commands registered is high tech: * qapi-commands.py generates qmp_init_marshal() that does the actual work * it also generates the magic to register it as a MODULE_INIT_QAPI function, so it runs when someone calls module_call_init(MODULE_INIT_QAPI) * main() calls module_call_init() QEMU needs to register a few non-qapified commands. Same high tech works: monitor.c has its own qmp_init_marshal() along with the magic to make it run in module_call_init(MODULE_INIT_QAPI). QEMU also needs to unregister commands that are not wanted in this build's configuration (commit 5032a16). Simple enough: qmp_unregister_commands_hack(). The difficulty is to make it run after the generated qmp_init_marshal(). We can't simply run it in monitor.c's qmp_init_marshal(), because the order in which the registered functions run is indeterminate. So qmp_init_marshal() registers qmp_unregister_commands_hack() separately. Since registering *appends* to the list of registered functions, this will make it run after all the functions that have been registered already. I suspect it takes a long and expensive computer science education to not find this silly. Dumb it down as follows: * Drop MODULE_INIT_QAPI entirely * Give the generated qmp_init_marshal() external linkage. * Call it instead of module_call_init(MODULE_INIT_QAPI) * Except in QEMU proper, call new monitor_init_qmp_commands() that in turn calls the generated qmp_init_marshal(), registers the additional commands and unregisters the unwanted ones.

| | | | | | | | | | | | | | | | | | | Implement query-cpu-model-expansion for target-i386. This should meet all the requirements while being simple. In the case of static expansion, it will use the new "base" CPU model, and in the case of full expansion, it will keep the original CPU model name+props, and append extra properties. A future follow-up should improve the implementation of type=full, so that it returns more detailed data, including every writable QOM property in the CPU object.
