For example, machines will - * have "-M <machine>" to its command line, while devices - * "-device <device>". It is automatically done by the - * framework. - * - after node : added as additional argument to the node name. - * This argument is added optionally when creating edges, - * by setting the parameter @after_cmd_line and - * @extra_edge_opts in #QOSGraphEdgeOptions. - * The framework automatically adds - * a comma before @extra_edge_opts, - * because it is going to add attributes - * after the destination node pointed by - * the edge containing these options, and automatically - * adds a space before @after_cmd_line, because it - * adds an additional device, not an attribute. - * - before node : added as additional argument to the node name. - * This argument is added optionally when creating edges, - * by setting the parameter @before_cmd_line in - * #QOSGraphEdgeOptions. This attribute - * is going to add attributes before the destination node - * pointed by the edge containing these options. It is - * helpful to commands that are not node-representable, - * such as "-fdsev" or "-netdev". - * - * While adding command line in edges is always used, not all nodes names are - * used in every path walk: this is because the contained or produced ones - * are already added by QEMU, so only nodes that "consumes" will be used to - * build the command line. Also, nodes that will have { "abstract" : true } - * as QMP attribute will loose their command line, since they are not proper - * devices to be added in QEMU. - * - * Example: - * - QOSGraphEdgeOptions opts = { - .arg = NULL, - .size_arg = 0, - .after_cmd_line = "-device other", - .before_cmd_line = "-netdev something", - .extra_edge_opts = "addr=04.0", - }; - QOSGraphNode * node = qos_node_create_driver("my_node", constructor); - qos_node_consumes_args("my_node", "interface", &opts); - * - * Will produce the following command line: - * "-netdev something -device my_node,addr=04.0 -device other" - */ - -/** - * Edge options to be passed to the contains/consumes *_args function. - */ -struct QOSGraphEdgeOptions { - void *arg; /* - * optional arg that will be used by - * dest edge - */ - uint32_t size_arg; /* - * optional arg size that will be used by - * dest edge - */ - const char *extra_device_opts;/* - *optional additional command line for dest - * edge, used to add additional attributes - * *after* the node command line, the - * framework automatically prepends "," - * to this argument. - */ - const char *before_cmd_line; /* - * optional additional command line for dest - * edge, used to add additional attributes - * *before* the node command line, usually - * other non-node represented commands, - * like "-fdsev synt" - */ - const char *after_cmd_line; /* - * optional extra command line to be added - * after the device command.
