trace: Add trace-file command to open/close/flush trace file This patch adds the trace-file command: trace-file [on|off|flush] Open, close, or flush the trace file. If no argument is given, the status of the trace file is displayed. The trace file is turned on by default but is only written out when the trace buffer becomes full. The flush operation can be used to force write out at any time. Turning off the trace file does not change the state of trace events; tracing will continue to the trace buffer. When the trace file is off, use "info trace" to display the contents of the trace buffer in memory. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> This commit also contains the trace-file sub-command from the following commit: commit 5ce8d1a957afae2c52ad748944ce72848ccf57bd Author: Prerna Saxena <prerna@linux.vnet.ibm.com> Date: Wed Aug 4 16:23:54 2010 +0530 trace: Add options to specify trace file name at startup and runtime This patch adds an optional command line switch '-trace' to specify the filename to write traces to, when qemu starts. Eg, If compiled with the 'simple' trace backend, [temp@system]$ qemu -trace FILENAME IMAGE Allows the binary traces to be written to FILENAME instead of the option set at config-time. Also, this adds monitor sub-command 'set' to trace-file commands to dynamically change trace log file at runtime. Eg, (qemu)trace-file set FILENAME This allows one to set trace outputs to FILENAME from the default specified at startup.

qmp: Dumb down how we run QMP command registration 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.

error: Use error_report_err() instead of monitor_printf() Both error_report_err() and monitor_printf() print to the same destination when monitor_printf() is used correctly, i.e. within an HMP monitor. Elsewhere, monitor_printf() does nothing, while error_report_err() reports to stderr. Most changed functions are HMP command handlers. These should only run within an HMP monitor. The one exception is bdrv_password_cb(), which should also only run within an HMP monitor. Four command handlers prefix the error message with the command name: balloon, migrate_set_capability, migrate_set_parameter, migrate. Pointless, drop. Unlike monitor_printf(), error_report_err() uses the error whole instead of just its message obtained with error_get_pretty(). This avoids suppressing its hint (see commit 50b7b00). Example: (qemu) device_add ivshmem,id=666 Parameter 'id' expects an identifier Identifiers consist of letters, digits, '-', '.', '_', starting with a letter. Try "help device_add" for more information The "Identifiers consist of..." line is new with this patch.

qdev: Replace cannot_instantiate_with_device_add_yet with !user_creatable cannot_instantiate_with_device_add_yet was introduced by commit efec3dd631d94160288392721a5f9c39e50fb2bc to replace no_user. It was supposed to be a temporary measure. When it was introduced, we had 54 cannot_instantiate_with_device_add_yet=true lines in the code. Today (3 years later) this number has not shrunk: we now have 57 cannot_instantiate_with_device_add_yet=true lines. I think it is safe to say it is not a temporary measure, and we won't see the flag go away soon. Instead of a long field name that misleads people to believe it is temporary, replace it a shorter and less misleading field: user_creatable. Except for code comments, changes were generated using the following Coccinelle patch: @@ expression DC; @@ ( -DC->cannot_instantiate_with_device_add_yet = false; +DC->user_creatable = true; | -DC->cannot_instantiate_with_device_add_yet = true; +DC->user_creatable = false; ) @@ typedef ObjectClass; expression dc; identifier class, data; @@ static void device_class_init(ObjectClass *class, void *data) { ... dc->hotpluggable = true; +dc->user_creatable = true; ... } @@ @@ struct DeviceClass { ... -bool cannot_instantiate_with_device_add_yet; +bool user_creatable; ... } @@ expression DC; @@ ( -!DC->cannot_instantiate_with_device_add_yet +DC->user_creatable | -DC->cannot_instantiate_with_device_add_yet +!DC->user_creatable ) Cc: Alistair Francis <alistair.francis@xilinx.com> Cc: Laszlo Ersek <lersek@redhat.com> Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: Markus Armbruster <armbru@redhat.com> Cc: Peter Maydell <peter.maydell@linaro.org> Cc: Thomas Huth <thuth@redhat.com> Acked-by: Alistair Francis <alistair.francis@xilinx.com> Reviewed-by: Thomas Huth <thuth@redhat.com> Reviewed-by: Marcel Apfelbaum <marcel@redhat.com> Acked-by: Marcel Apfelbaum <marcel@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Message-Id: <20170503203604.31462-2-ehabkost@redhat.com> [ehabkost: kept "TODO remove once we're there" comment] Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

qapi: Change Netdev into a flat union This is a mostly-mechanical conversion that creates a new flat union 'Netdev' QAPI type that covers all the branches of the former 'NetClientOptions' simple union, where the branches are now listed in a new 'NetClientDriver' enum rather than generated from the simple union. The existence of a flat union has no change to the command line syntax accepted for new code, and will make it possible for a future patch to switch the QMP command to parse a boxed union for no change to valid QMP; but it does have some ripple effect on the C code when dealing with the new types. While making the conversion, note that the 'NetLegacy' type remains unchanged: it applies only to legacy command line options, and will not be ported to QMP, so it should remain a wrapper around a simple union; to avoid confusion, the type named 'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions' in its place. Then, in the C code, we convert from NetLegacy to Netdev as soon as possible, so that the bulk of the net stack only has to deal with one QAPI type, not two. Note that since the old legacy code always rejected 'hubport', we can just omit that branch from the new 'NetLegacyOptions' simple union.
