interface menus. Parallel port #1 is implemented, and I left stubs for
parallel port #2 in case we want to ever add it. If the parallel port
is enabled, the init method of parallel.cc does an fopen() on the output
file. If disabled, or if the fopen fails, the file handler remains
NULL and no characters are printed. There is no attempt to enable/disable
the operation of the parallel port, only the output to a file.
removed! I used this trick sometimes to check that a function returned
what I expected, like assert (func () == 0), but this caused the
func() to never get called. Oops.
will dump core, and the core can sometimes be loaded into the debugger
to give some hints as to what is going on. This could be especially
useful when the bochs debugger is off.
- try to do something reasonable when abort() doesn't exist on the system.
which were generated with gcc -MM to the end of each Makefile.in
so that make understands which files depend on which. Basically,
everything depends on bochs.h, which depends on everything, which
is not ideal.
- rework the order of initialization with and without the control panel.
The thing that was bothering me most was the command line options were
being processed after the user had set everything in the control panel.
This is clearly not what's expected--the command line options should
affect the startup defaults of the control panel, but whatever the user
chooses in the cpanel menus is the final choice.
- if the control panel (config interface) is not wanted, the user can
put "-nocp" or "-nocontrolpanel" as the FIRST argument on the command
line. Also, the "-psn" option which is automatically passed in by
MacOS X when you doubleclick the application causes the control panel
to be disabled. In this case, the order of operations is:
1. read bochsrc
2. parse command line options.
- if the control panel is enabled (default), the command line options are
parsed to provide the startup defaults for the control panel, but the
control panel settings are the final answer. So the order is:
1. parse command line options
2. run control panel (if user chooses, he can read bochsrc from menus)
- I haven't tested command line options with the debugger yet.
--with-amigaos is allowed and sets up the makefiles correctly. It
defines a symbol called BX_WITH_AMIGAOS, which should be used in
#if..#endif constructs that are specific to amigaos.
- if --enable-cdrom is used with --with-amigaos, the cdrom_amigaos.o
object file will be added to CDROM_OBJS in the iodev makefile.
X servers that I've seen, however on other X servers it makes all
key mappings into absolute junk. We need to continue to work on this
patch to support all X servers and all key maps.
<dieter.mittelmaier@freenet.de> which fixes X11 keyboard mapping
on German keyboards using Keycodes instead of Keysyms.
His comments are:

which notifies them that the mouse_enabled bit has changed. Now that
mouse_enabled can be initialized or modified by parameter events in
addition to GUI events, the guis must be prepared for it. I have pasted
empty method definitions into mouse_enabled_changed_specific for all
guis except for X11, which I did the right way. The implementation
of this function must use the argument "val" rather than reading the
parameter.
goes in/out of mouse capture mode. This is critical because
bx_options.Omouse_enabled is used to control whether the mouse
events are sent into the hardware queue or not (keyboard.cc).
This is only a partial fix though, because changing the mouse
enabled setting in the control panel has no effect on the gui.
control panel are all implemented as bx_list_c, and look much like
they did before.
- removed many hardcoded UI functions from control.cc, since the
much more general "text_ask" methods have replaced them.
- add range checking on integer parameter values. This exposed several
cases where my initial value for an integer parameter was not in range.
- cleaned up behavior of get/set methods. The get/set methods allow the
handler to override the value that is returned/set, or perform side
effects.
- the title parameter of a bx_list_c now defaults to the name.
- now bx_param_c fields that used to be private are protected instead
- removed references to bx_any
- moved definition of set_handler from siminterface.h to siminterface.cc.
I was considering with doing a "set" of the old value when the
handler is first installed, but that remains commented out.
- BX_BOOT_DISKA and BX_BOOT_DISKC are now 0,1 so that they can correspond
with the values of a bx_param_enum_c. For a while they were 0x00 and 0x80
corresponding to the numbering convention of the bios, but it didn't
really matter.
been converted into parameters temporarily have the letter "O" appended
to their name. I don't want to keep it this way, but it has helped
in the conversion process because the compiler refuses to compile the
old uses of the name. Before I started using the "O" trick, there were
many bugs like this: if (bx_options.diskc.present) {...}
This was legal with the new parameters, but it was testing whether the
parameter structure had been created, instead of testing the value of
the present parameter. Renaming present to Opresent turns this into
a compile error, which points out the incorrect use of the param.
- the "--disable-control-panel" no longer works, I'm afraid. I can no
longer support this and continue progress.
crash in the mouse code. The particular problem was that init_done
was never initialized to zero, but it always turned out to be zero
on my system. This may explain why it worked for me but crashed
for him.
data structures, see bx_init_options in main.cc. The implementation
of this menu and all its choices is 17 lines long, see do_mem_options_menu
in gui/control.cc.
now the whole "Bochs Memory Options" menu uses new style parameters.
The next step is to remove the hardcoded stuff that generates and runs
this menu, and replace it with general menu building code. All you should
need to create this menu is the string "Bochs Memory Options", and the
IDs of the bx_param_c options that should appear on the menu. The
bx_param_c structure for each parameter tell what type it is, how to
display it, constraints on the value, what to do when the parameter
changes.
declared as bx_param_c * types in the bx_options structure. They are
initialized in main.cc (bx_init_options) with default values.
Access to parameters of this type should always be like this:
bx_options.mouse_enabled->get ();
bx_options.mouse_enabled->set (newval);
Eventually I will be transferring all options to this format.
when main.cc no longer had one. Now compiling with debugger is working
with the control panel. To get the control panel, you have to click
the snapshot button, and to get the debugger, you have to press ^C.
These should be better integrated (maybe a control panel menu choice
that jumps into the debugger and a debugger command that starts the
runtime control panel...)
