+= How to use the QAPI code generator =
+
+* Note: as of this writing, QMP does not use QAPI. Eventually QMP
+commands will be converted to use QAPI internally. The following
+information describes QMP/QAPI as it will exist after the
+conversion.
+
+QAPI is a native C API within QEMU which provides management-level
+functionality to internal/external users. For external
+users/processes, this interface is made available by a JSON-based
+QEMU Monitor protocol that is provided by the QMP server.
+
+To map QMP-defined interfaces to the native C QAPI implementations,
+a JSON-based schema is used to define types and function
+signatures, and a set of scripts is used to generate types/signatures,
+and marshaling/dispatch code. The QEMU Guest Agent also uses these
+scripts, paired with a seperate schema, to generate
+marshaling/dispatch code for the guest agent server running in the
+guest.
+
+This document will describe how the schemas, scripts, and resulting
+code is used.
+
+
+== QMP/Guest agent schema ==
+
+This file defines the types, commands, and events used by QMP. It should
+fully describe the interface used by QMP.
+
+This file is designed to be loosely based on JSON although it's technically
+executable Python. While dictionaries are used, they are parsed as
+OrderedDicts so that ordering is preserved.
+
+There are two basic syntaxes used, type definitions and command definitions.
+
+The first syntax defines a type and is represented by a dictionary. There are
+two kinds of types that are supported: complex user-defined types, and enums.
+
+A complex type is a dictionary containing a single key who's value is a
+dictionary. This corresponds to a struct in C or an Object in JSON. An
+example of a complex type is:
+
+ { 'type': 'MyType',
+ 'data' { 'member1': 'str', 'member2': 'int', '*member3': 'str } }
+
+The use of '*' as a prefix to the name means the member is optional. Optional
+members should always be added to the end of the dictionary to preserve
+backwards compatibility.
+
+An enumeration type is a dictionary containing a single key who's value is a
+list of strings. An example enumeration is:
+
+ { 'enum': 'MyEnum', 'data': [ 'value1', 'value2', 'value3' ] }
+
+Generally speaking, complex types and enums should always use CamelCase for
+the type names.
+
+Commands are defined by using a list containing three members. The first
+member is the command name, the second member is a dictionary containing
+arguments, and the third member is the return type.
+
+An example command is:
+
+ { 'command': 'my-command',
+ 'data': { 'arg1': 'str', '*arg2': 'str' },
+ 'returns': 'str' ]
+
+Command names should be all lower case with words separated by a hyphen.
+
+
+== Code generation ==
+
+Schemas are fed into 3 scripts to generate all the code/files that, paired
+with the core QAPI libraries, comprise everything required to take JSON
+commands read in by a QMP/guest agent server, unmarshal the arguments into
+the underlying C types, call into the corresponding C function, and map the
+response back to a QMP/guest agent response to be returned to the user.
+
+As an example, we'll use the following schema, which describes a single
+complex user-defined type (which will produce a C struct, along with a list
+node structure that can be used to chain together a list of such types in
+case we want to accept/return a list of this type with a command), and a
+command which takes that type as a parameter and returns the same type:
+
+ mdroth@illuin:~/w/qemu2.git$ cat example-schema.json
+ { 'type': 'UserDefOne',
+ 'data': { 'integer': 'int', 'string': 'str' } }
+
+ { 'command': 'my-command',
+ 'data': {'arg1': 'UserDefOne'},
+ 'returns': 'UserDefOne' }
+ mdroth@illuin:~/w/qemu2.git$
+
+=== scripts/qapi-types.py ===
+
+Used to generate the C types defined by a schema. The following files are
+created:
+
+$(prefix)qapi-types.h - C types corresponding to types defined in
+ the schema you pass in
+$(prefix)qapi-types.c - Cleanup functions for the above C types
+
+The $(prefix) is an optional parameter used as a namespace to keep the
+generated code from one schema/code-generation separated from others so code
+can be generated/used from multiple schemas without clobbering previously
+created code.
+
+Example:
+
+ mdroth@illuin:~/w/qemu2.git$ python scripts/qapi-types.py \
+ --output-dir="qapi-generated" --prefix="example-" < example-schema.json
+ mdroth@illuin:~/w/qemu2.git$ cat qapi-generated/example-qapi-types.c

+ char * string;
+ };
+
+ void qapi_free_UserDefOne(UserDefOne * obj);
+

+
+
+=== scripts/qapi-visit.py ===
+
+Used to generate the visitor functions used to walk through and convert
+a QObject (as provided by QMP) to a native C data structure and
+vice-versa, as well as the visitor function used to dealloc a complex
+schema-defined C type.
+
+The following files are generated:
+
+$(prefix)qapi-visit.c: visitor function for a particular C type, used
+ to automagically convert QObjects into the
+ corresponding C type and vice-versa, as well
+ as for deallocating memory for an existing C
+ type

+
+Used to generate the marshaling/dispatch functions for the commands defined
+in the schema. The following files are generated:
+
+$(prefix)qmp-marshal.c: command marshal/dispatch functions for each
+ QMP command defined in the schema. Functions
+ generated by qapi-visit.py are used to
+ convert QObjects recieved from the wire into
+ function parameters, and uses the same
+ visitor functions to convert native C return
+ values to QObjects from transmission back
+ over the wire.
+
+$(prefix)qmp-commands.h: Function prototypes for the QMP commands
+ specified in the schema.
