Bochs/bochs/gui/siminterface.h
Volker Ruppert 7956e47de8 - removed USB port option parameter and store device and option in one single
string. This is better for devices that need to know all it's options when
  connecting to the port. Device name and option should be separated with a
  colon. The USB device 'disk' now uses this format ('disk:usbdisk.img).
- the pciusb plugin must be linked with cdrom.o

//
// Intro to siminterface by Bryce Denney:
//
// Before I can describe what this file is for, I have to make the
// distinction between a configuration interface (CI) and the VGA display
// window (VGAW). I will try to avoid the term 'GUI' because it is unclear
// if that means CI or VGAW, and because not all interfaces are graphical
// anyway.
//
// The traditional Bochs screen is a window with a large VGA display panel and
// a series of buttons (floppy, cdrom, snapshot, power). Over the years, we
// have collected many implementations of the VGAW for different environments
// and platforms; each implementation is in a separate file under gui/*:
// x.cc, win32.cc, beos.cc, macintosh.cc, etc. The files gui.h and gui.cc
// define the platform independent part of the VGAW, leaving about 15 methods
// of the bx_gui_c class undefined. The platform dependent file must
// implement the remaining 15 methods.
//
// The configuration interface is relatively new, started by Bryce Denney in
// June 2001. The CI is intended to allow the user to edit a variety of
// configuration and runtime options. Some options, such as memory size or
// enabling the ethernet card, should only be changed before the simulation
// begins; others, such as floppy disk image, instructions per second, and
// logging options can be safely changed at runtime. The CI allows the user to
// make these changes. Before the CI existed, only a few things could be
// changed at runtime, all linked to clicking on the VGAW buttons.
//
// At the time that the CI was conceived, we were still debating what form the
// user interface part would take: stdin/stdout menus, a graphical application
// with menus and dialogs running in a separate thread, or even a tiny web
// server that you can connect to with a web browser. As a result the
// interface to the CI was designed so that the user interface of the CI
// could be replaced easily at compile time, or maybe even at runtime via
// a plugin architecture. To this end, we kept a clear separation between
// the user interface code and the siminterface, the code that interfaces with
// the simulator. The same siminterface is used all the time, while
// different implementations of the CI can be switched in reasonably easily.
// Only the CI code uses library specific graphics and I/O functions; the
// siminterface deals in portable abstractions and callback functions.
// The first CI implementation was a series of text mode menus implemented in
// textconfig.cc.
//
// The configuration interface MUST use the siminterface methods to access the
// simulator. It should not modify settings in some device with code like
// bx_floppy.s.media[2].heads = 17. If such access is needed, then a
// siminterface method should be written to make the change on the CI's behalf.
// This separation is enforced by the fact that the CI does not even include
// bochs.h. You'll notice that textconfig.cc includes osdep.h, textconfig.h,
// and siminterface.h, so it doesn't know what bx_floppy or bx_cpu_c are.
// I'm sure some people will say is overly restrictive and/or annoying. When I
// set it up this way, we were still talking about making the CI in a seperate
// process, where direct method calls would be impossible. Also, we have been
// considering turning devices into plugin modules which are dynamically
// linked. Any direct references to something like bx_floppy.s.media[2].heads
// would have to be reworked before a plugin interface was possible as well.
//
// The siminterface is the glue between the CI and the simulator. There is
// just one global instance of the siminterface object, which can be referred
// to by the global variable bx_simulator_interface_c *SIM. The base class
// bx_simulator_interface_c, contains only virtual functions and it defines the
// interface that the CI is allowed to use. In siminterface.cc, a class
// called bx_real_sim_c is defined with bx_simulator_interface_c as its parent
// class. Bx_real_sim_c implements each of the functions. The separation into
// parent class and child class leaves the possibility of making a different
// child class that talks to the simulator in a different way (networking for
// example). If you were writing a user interface in a separate process, you
// could define a subclass of bx_simulator_interface_c called
// bx_siminterface_proxy_c which opens up a network port and turns all method
// calls into network sends and receives. Because the interface is defined
// entirely by the base class, the code that calls the methods would not know
// the difference.
//
// An important part of the siminterface implementation is the use of parameter
// classes, or bx_param_*. The parameter classes are described below, where
// they are declared. Search for "parameter classes" below for details.
//
// Also this header file declares data structures for certain events that pass
// between the siminterface and the CI. Search for "event structures" below.
//////////////////////////////////////////////////////
// BX_USE_TEXTCONFIG should be set to 1 when the text mode configuration interface
// is compiled in. This gives each type of parameter a text_print and text_ask
// method (defined in gui/textconfig.cc) so that you can call text_ask() on any
// kind of parameter to ask the user to edit the value.
//
// I have been considering whether to use the same strategy for the
// wxWidgets interface, but I'm not sure if I like it. One problem is
// that in order to declare member functions that are useful for
// wxWidgets, the wxWidgets header files would have to be included
// before the param object definitions. That means that all the
// wxWidgets headers would have be included when compiling every
// single bochs file. One of the things I like about the separation
// between the simulator and CI is that the two parts can be
// compiled without any knowledge of the other. Bochs doesn't include
// <wx.h>, and the wxWidgets CI (wxmain.cc) doesn't need to include <bochs.h>.
// Aside from making compiles faster, this enforces the use of the siminterface
// so it keeps the interface clean (important when we may have multiple UI
// implementations for example). This argues for keeping UI-specific
// structures out of the simulator interface. It certainly works ok for the
// text interface, but that's because FILE* is standard and portable.

///////////////////////////////////////////////////////////////////
// event structures for communication between simulator and CI
///////////////////////////////////////////////////////////////////
// Because the CI (configuration interface) might be in a different
// thread or even a different process, we pass events encoded in data
// structures to it instead of just calling functions. Each type of
// event is declared as a different structure, and then all those
// structures are squished into a union in BxEvent. (BTW, this is
// almost exactly how X windows event structs work.)
//
// These are simple structs, unblemished by C++ methods and tricks.
// No matter what event type it is, we allocate a BxEvent for each
// one, as opposed to trying to save a few bytes on small events by
// allocating only the bytes necessary for it. This makes it easy and
// fast to store events in a queue, like this
// BxEvent event_queue[MAX_EVENTS];
//
// Events come in two varieties: synchronous and asynchronous. We
// have to worry about sync and async events because the CI and the
// simulation may be running in different threads. An async event is
// the simplest. Whichever thread originates the event just builds
// the data structure, sends it, and then continues with its business.
// Async events can go in either direction. Synchronous events
// require the other thread to "respond" before the originating thread
// can continue. It's like a function with a return value; you can't
// continue until you get the return value back.
//
// Examples:
//
// async event: In the wxWidgets implementation, both the CI and the
// VGAW operate in the wxWidgets GUI thread. When the user presses a
// key, wxWidgets sends a wxKeyEvent to the VGAW event handler code in
// wx.cc. The VGAW handler then builds a BxEvent with
// type=BX_ASYNC_EVT_KEY, and fills in the bx_key and raw_scancode
// fields. The asynchronous event is placed on the event_queue for
// the simulator, then the VGAW handler returns. (With wxWidgets and
// many other graphical libaries, the event handler must return
// quickly because the window will not be updated until it's done.)
// Some time later, the simulator reaches the point where it checks
// for new events from the user (actually controlled by
// bx_keyb_c::periodic() in iodev/keyboard.cc) and calls
// bx_gui.handle_events(). Then all the events in the queue are
// processed by the simulator. There is no "response" sent back to
// the originating thread.
//
// sync event: Sometimes the simulator reaches a point where it needs
// to ask the user how to proceed. In this case, the simulator sends
// a synchronous event because it requires a response before it can
// continue. It builds an event structure, perhaps with type
// BX_SYNC_EVT_ASK_PARAM, sends it to the user interface
// using the event handler function defined by set_notify_callback(),
// and pauses the simulation. The user interface asks the user the
// question, and puts the answer into the BxEvent.retcode field. The
// event handler function returns the modified BxEvent with retcode
// filled in, and the simulation continues. The details of this
// transaction can be complicated if the simulation and CI are not
// in the same thread, but the behavior is as described.

// doesn't exist now of course) and then when certain values change, the

// parameter classes: bx_param_c and family
////////////////////////////////////////////////////////////////////
//
// All variables that can be configured through the CI are declared as
// "parameters" or objects of type bx_param_*. There is a bx_param_*
// class for each type of data that the user would need to see and
// edit, e.g. integer, boolean, enum, string, filename, or list of
// other parameters. The purpose of the bx_param_* class, in addition
// to storing the parameter's value, is to hold the name, description,
// and constraints on the value. The bx_param_* class should hold
// everything that the CI would need to display the value and allow
// the user to modify it. For integer parameters, the minimum and
// maximum allowed value can be defined, and the base in which it
// should be displayed and interpreted. For enums, the
// bx_param_enum_c structure includes the list of values which the
// parameter can have.
//
// Also, some parameter classes support get/set callback functions to
// allow arbitrary code to be executed when the parameter is get/set.
// An example of where this is useful: if you disable the NE2K card,
// the set() handler for that parameter can tell the user interface
// that the NE2K's irq, I/O address, and mac address should be
// disabled (greyed out, hidden, or made inaccessible). The get/set
// methods can also check if the set() value is acceptable using
