add SVGALIB display library by Igor Popik <igipop@wsfiz.edu.pl>
While it's running, you can press F12 to escape into the runtime config
menu, and then you can change disks or quit or whatever.
Better not try it with the bochs debugger...you could get stuck.

- The Bochs debugger uses BX_WITH_WX to decide to change to wxWindows debugger
behavior: sending a synchronous message to the config interface to get a new
command, sending all dbg_printf output to the config interface, deciding
whether to trap control-C, etc. But now that it's possible to compile with
BX_WITH_WX and BX_WITH_other_things, this isn't quite right anymore. With
this change, we now use calls to a new method SIM->is_wx_selected() to decide
which behavior to use. This method is equivalent to checking if the display
library variable is set to "wx", but it's implemented in such a way that it
only has to check a boolean for each call to SIM->is_wx_selected().
- in siminterface.cc, init some local variables to 0 to avoid compile
warnings.

For a whole lot of configure options, I put #if...#endif around code that
is specific to the option, even in files which are normally only compiled
when the option is on. This allows me to create a MS Visual C++ 6.0
workspace that supports many of these options. The workspace will basically
compile every file all the time, but the code for disabled options will
be commented out by the #if...#endif.
This may one day lead to simplification of the Makefiles and configure
scripts, but for the moment I'm leaving Makefiles and configure scripts
alone.

BX_SUPPORT_APIC (cpu/apic.cc)
BX_SUPPORT_X86_64 (cpu/*64.cc)

Special signal handling is done if bx_gui_sighandler is true.

New behaviour is:
. No command line arg (user want to load or create a new conf file)
-> no .bochsrc is loaded

-> conf file is loaded
-> if found Run the simulation

. After selection of "2. Read options from..."
-> defaults to "5. Begin simulation"
- fix "enable-control-panel" behaviour in configure.in.
- check if a romimage was supplied in the conf file.
If not, print a hint about a missing/corrupt conf file.
I hope I did not break anything, notably the Carbon gui
interface at runtime. The behaviour of the button handlers was wrong if bochs
is configured with plugins and all display libs enabled, wxWindows is present
and a gui using textconfig is selected.
The wx cdrom button still doesn't work since get_first_cdrom() always returns
NULL.
- add a new global struct bx_startup_flags which stores argc,argv and
when necessary, the WinMain arguments hInstance, hPrevInstance, etc.
The new struct is defined in gui/siminterface.h because it is needed in
both the main.cc code and in wxmain.cc and textconfig.cc (which don't
include bochs.h).
- rename main() to bxmain() and create new main() and WinMain().
main() and WinMain() just fill in the bx_startup_flags and then
call bxmain(). Only one is defined at a time, of course.
- so far, WinMain is ONLY used when compiling with wxWindows on win32.
It may be useful in other contexts as well, but I don't want to enable
it in any other situation without some serious testing of different
configurations.

These files are part of the wx plugin, and they should not be linked

- if translation=auto :
. translation=none if cylinders <=1024 and heads <=16
. translation=large if cylinders * heads <= 131072
. transaltion=lba otherwise
- changes default translation value to "auto"
- add example in .bochsrc
"bx_bool" which is always defined as Bit32u on all platforms. In Carbon
specific code, Boolean is still used because the Carbon header files
define it to unsigned char.
- this fixes bug [ 623152 ] MacOSX: Triple Exception Booting win95.
The bug was that some code in Bochs depends on Boolean to be a
32 bit value. (This should be fixed, but I don't know all the places
where it needs to be fixed yet.) Because Carbon defined Boolean as
an unsigned char, Bochs just followed along and used the unsigned char
definition to avoid compile problems. This exposed the dependency
on 32 bit Boolean on MacOS X only and led to major simulation problems,
that could only be reproduced and debugged on that platform.
- On the mailing list we debated whether to make all Booleans into "bool" or
our own type. I chose bx_bool for several reasons.
1. Unlike C++'s bool, we can guarantee that bx_bool is the same size on all
platforms, which makes it much less likely to have more platform-specific
simulation differences in the future. (I spent hours on a borrowed
MacOSX machine chasing bug 618388 before discovering that different sized
Booleans were the problem, and I don't want to repeat that.)
2. We still have at least one dependency on 32 bit Booleans which must be
fixed some time, but I don't want to risk introducing new bugs into the
simulation just before the 2.0 release.

value instead of a 32 bit value. Unfortunately there were many uses
of bx_param_num_c::get() which depended on its size, and they were
all broken by this change. So in this rev I am changing get() to
return a 32bit unsigned again. If you really want a 64bit value (which
is quite rare) you should call get64() instead.

Detailed description:
A number of changes to the Carbon Code to improve how well it meshes with the
MacOS X user experience as well as to make sure that all of more recently added
toolbar buttons actually work.
Specific changes include:
Added partial keymap support. (Keymaps don't yet affect what the user types
but an X11 keymap can be used to enable pasting)
Copying of text screens added
Pasting of text as keyboard input added
Copy, Paste, Reset, and Snapshot menu items now work the same as the
corresponding toolbar elements
Revamped icon handling to use Control Manager IconControls,
thus removing icon display code and greatly simplifying icon click handling code
while adding better behaviours (icons that darken when clicked, track mouse movement,
and only do something if the mouse is released atop of them as well as gaining
the ability to be disabled)
Tweaked Paste toolbar and menu items to only be enabled if key mapping is in use AND the
clipboard contains text
Tweaked Copy and Snapshot toolbar and menu elements to only be enabled if
the screen mode is text.
Tweaked User Keys toolbar element to only be enabled if there are user keys
defined to be sent
Tweaked Configure toolbar element to only be enabled if a tty is available
(as in the emulator was started from a terminal)
Respaced toolbar icons to match Aqua Toolbars
Disabled menu items that are not currently handled (undo, clear, cut, disk eject)
Full screen backdrop resettled all across the screen
Fixed the callback interface so that when a Panic needs to ask the user about continuing
it actually works appropriately.
----------------------------------------------------------------------
bx_shadow_num_c able to handle pointers to 64 bit values. This
allows x86-64 and wxWindows to coexist.
- I had a number of duplicate constructors for bx_shadow_num_c,
with an without the description arg. I eliminated the ones
that had no description, and also removed the min/max arg from
all. I still need a bunch of constructors though, for
Bit64u*, Bit64s*, Bit32u*, Bit32s*, Bit16u*, Bit16s*, Bit8u*, Bit8s*.
Having all these constructors allows us to write
new bx_shadow_num (bxid, name, description, &value)
for basically any integer variable. They are all handled by the same class.
- these changes led to minor touchups in cpu/init.cc and iodev/keyboard.cc
- modified:
configure main.cc cpu/init.cc iodev/keyboard.cc
gui/siminterface.cc gui/siminterface.h
X11 keymap files. This okay since the keysym values are identical. The "AltGr"
key on European keyboards doesn't work with wxGTK 2.3.3 because the keysym
GDK_Mode_switch is not handled in wxGTK.
- German keymap table for wx and wxgtkkeys.h are no longer needed
different versions of the code for wxWindows and non-wxWindows and the GDB
stub did not accept any command line options at all.
- IMPORTANT CHANGE: the quick start option used to cause two things:
1) read the bochsrc immediately, 2) start simulation immediately without
going into the config interface. This has changed in a subtle way.
Now, we always try to read the bochsrc immediately. Then if the quick
start option is on, we start the simulation immediately.
- add "Restore Factory Default Configuration" in text config menu. It was
already there in wx. Now the default choice is always "5. Begin simulation"
and because the bochsrc is always read now, this works.
- When the user chooses "Read configuration file" from either text mode
or wx interfaces, reset all bochs parameters first, then read in the
new file. This means that every time you read a configuration file
you are starting from a consistent "blank slate".
- move much of the code from bx_do_text_config_interface into bx_init_main
so that wxWindows and non-wxWindows code uses the same logic. There was
only a tiny bit left in bx_do_text_config_interface so I eliminated it.
- move the "help" message into a separate function print_usage()
- detect all flags (cmdline args that start with -) in a loop, instead of
a big if/else. This makes it easy to add others.
- fix problem with Carbon gui, so that -psn arg gets ignored
- print usage if you type -h, --help, or if flags are not recognized
- code that called io->set_log_action (that sets the log action for all
devices) was only called if the configuration interface was on; I'm not
sure why. Now it is called all the time.
- the wxWindows equivalent of main() is called MyApp::OnInit. Now OnInit
and main() are very similar. They both call bx_init_siminterface, then
bx_init_main (and quit if it fails), then show the config interface if
quickstart is off, and then simulate.
- modified: main.cc gui/control.cc gui/wxmain.cc
specific to X windows. I changed a few names of variables and methods to
sound less X windows specific, for example in the BXKeyEntry struct
the "xwinKey" field is now called "hostKey".
- remove the hacks in bx_keymap_c::loadKeymap that checked that every
keysym started with "XK_". Now I can still make that check, but it
is done in x.cc's convertStringToXKeysym() instead.
- in sdl.cc, load the keymap in specific_init function. I had to
create a conversion function from SDL key names to SDLkey values.
I created a table of key names and associated values, and I just
do a strcmp on each name. It's not a fast algorithm obviously but this
conversion only has to be done for maybe 200 keys at startup time.
- added a key map file for SDL called sdl-pc-us.map. Since this has
basically all the SDLK_* symbols defined, it is a good starting point
if you need to make any other keymaps.
- modified: gui/keymap.cc gui/keymap.h gui/sdl.cc gui/x.cc iodev/keyboard.cc
- added: gui/sdlkeys.h gui/keymaps/sdl-pc-us.map
wxLog::SetActiveTarget (new wxLogStderr ());
which used to be inside #ifdef __WXDEBUG__ ... #endif. This fixes the
problem of tons of little debug message dialogs appearing in wxwindows
libraries built without debug support.
- This reverts revision 1.61. I cannot figure out why I had trouble back on
Sept 27, because now both my debug and release libraries work ok with the
SetActiveTarget line.
the toolbar button and the mouse capture shortcuts (F12 and middle button)
call ToggleMouse(). The only difference is that the first time you
press the toolbar button it gives a little message about mouse capture
and how to turn it off.
- modified: gui/wx.cc gui/wxmain.cc gui/wxmain.h
Quit while the simulation was running. I used to just do
wxFrame::Close(TRUE) in the wxwindows thread, but the simulation
thread would keep on running even after the window had disappeared.
If the simulation thread sent any messages to the gui, it could
segfault. Now, when you click on Quit it asks the simulator to
quit, but does not close the gui. When the simulator thread finally
quits, THEN it calls wxFrame::Close(TRUE) from the sim_thread (with
appropriate gui mutex). Such tricks are only needed when the
simulation is running. I hope this will fix bug #616142: "wx: crash
from events after gui shutdown".
- move MyFrame::closing flag out into a global variable wxBochsClosing
so that it will be valid even when the MyFrame is deleted. See
comments on in wxmain.h.
- when wxBochsClosing is set, don't create any new windows. If any
errors appear, just print them to stderr because the gui is just
about to be closed.
- fix comment in SimThread::Entry to talk about longjmp instead of
kill_bochs_request
- (minor) move contents of DefaultCallback2 into DefaultCallback. It
doesn't refer to the wxApp at all. This is a bit safer in case it
gets called when the wxApp is in the process of being deleted.
- modified: gui/wxmain.cc gui/wxmain.h
This must be done carefully though, because the call to SDL_WarpPointer
generates a mouse motion event of its own. To work around this, I have
added code that should ignore motion events generated by SDL_WarpPointer.
This should fix bug [ 619283 ] SDL: os mouse pointer leaves the window.
On Linux, SDL 1.2.3 it works fine.
bx_list_c can now be displayed as either a wxStaticBox with the
child parameters inside, or as a wxNotebook with each child
parameter in a separate tab. (The children can also be lists of
course.) The default display is the wxStaticBox type, but if you
set the option bit bx_list_c::USE_TAB_WINDOW in the list,
ParamDialog will use the wxNotebook display instead.
- to get the param trees working, I created a new struct
AddParamContext, which is passed to AddParam(). This struct is
critical when AddParam calls itself recursively to display lists
within lists.
- use the wxNotebook display feature for the ATA0,1,2,3 controller
dialog box. Now instead of being hundreds of pixels tall, it is
reasonable height with three different tabs. This fixed bug
#619074: "wx: ATA interface editor too tall" and was the whole
reason I started messing with this at all.
plus some minor cleanups
- when I added the enum constant bx_list_c::USE_TAB_WINDOW, I also
removed the BX_ prefix from all the other enum constants that are
used in parameter options in siminterface.cc. Since these constants
are enums within a class, there is no possibility of namespace
conflicts so the prefix is not needed.
- added wxADJUST_MINSIZE to all wxChoice controls, since that tells
wxWindows to adjust its size to the length of the longest string.
- instead of calling SetSize or SetSizeHints on every textcontrol with
a hardcoded width, I am using just two wxSize specifications for
everything: either normalTextSize or longTextSize.
- edit names of a few menus and params. For example now instead of
the tab saying "Master ATA device on channel 0" it will say
"First HD/CD on channel 0".

to be signed instead of unsigned, it was looking up color values
like wxBochsPalette[-126] instead of wxBochsPalette[130]. This affected
any colors in the palette between 128 and 255. I simply hanged newBits
to signed, and it fixed bug #618462: wx: 256 color modes not working properly
- I am still not satisfied with the way that wxWindows maps colors on an
8-bit display, but that is a different issue.
after the palette changes. This makes the iodev/vga.cc code do the
right thing. This also fixes the toolstar splash screen, but at a
fraction of the cost of the solution in rev 1.37.
need to be updated. This was impossible before, because we only stored the
RGB values in wxScreen. I added a new array called wxPixel that stores the
8-bit color index that should be displayed. Now if the VGA palette changes,
I use wxPixel data to reconstruct wxScreen using the new palette.
- this fixes the display of the splash screen of the Toolstar disk, since
it relied on drawing the picture and then fading the colormap from back
up to the normal values. I was hoping it would fix the splash screen of
win95 too, but it does not.
so that windows types can be used in fields, for example in cdrom.h:
#ifdef WIN32
HANDLE cdrom_interface::hFile;
#endif
- since every file includes bochs.h, I removed includes of <windows.h>
everywhere else
- modified: bochs.h cpu/extdb.cc gui/win32.cc gui/wx.cc iodev/cdrom.cc
iodev/eth_win32.cc iodev/floppy.cc
instead of winmm being a part of GUI_LINK_OPTS_WIN32 only, it is
placed in @DEVICE_LINE_OPTS@ so that it will be used for sdl, rfb, wx,
etc.
- solve compile problems when building bximage, niclist, and any other
console based program. The compile flags returned by wx-config and
sdl-config did strange things to these console programs, for example
redefining main to SDL_main. Because I wanted to use the
configure-generated CFLAGS to compile the programs, but I wanted to
avoid including GUI specific compile options, I split up the configure's
@CFLAGS@ variable into @CFLAGS@ and @GUI_CFLAGS@, and split
@CXXFLAGS@ into @CXXFLAGS@ and @GUI_CXXFLAGS@. All programs in the
Bochs binary will use both, but the console programs will just use
@CFLAGS@ or @CXXFLAGS@.
- gui/Makefile.in, I no longer use the gui specific CFLAGS variables,
SDL_CFLAGS and WX_CXXFLAGS. These values are included in CFLAGS and
CXXFLAGS now.
- modified: configure.in, configure, all Makefile.in's
conditionally include <windows.h>. This may seem like a drastic step
for just one little type, but I expect before long we may want to use
other symbols like VK_F12 which are also in windows.h. In a cygwin
compile this is required.
on the wxWindows interface. There are many more changes here than
absolutely required to fix the memory leaks. Instead, I've tried to
clean things up so that it does the right thing, and is easier to
read and maintain.
- For events that the text mode interface is going to ignore anyway, I #ifdefed
the event creation code instead of calling new and then delete.
- now all synchronous events in siminterface.cc are created as local variables
on the stack. Some of them were allocated with new before, and yes some of
them leaked.
- now I ignore the result of sim_to_ci_event (&event). It was always
returning a pointer to the input event anyway. This makes the event
sending code simpler.
- wxmain.cc:
- in the BxEvent handling functions, now all cases "break" down to common
code at the end which deletes async events. This is easier to read than
having each case handle the delete individually.
- in OnLogMsg, do not delete the event here because it is now handled
in the common code of OnSim2CIEvent instead.
- thanks to Christophe for pointing out the location of the worst
memory leak.
- make bx_init_main return -1 if any parse errors occur.
- wxWindows: if bx_init_main returns -1, don't even show the application
window. You'll get an error dialog and then it exits. So far this
only happens if you run with -q and the parse fails.
- non-wxWindows: if bx_init_main returns -1, just exit. So far this
only happens if you run with -q and the parse fails.
- with these changes, handling of bochsrc parse errors seems to work
as you would expect. And it certainly doesn't go into an infinite
recursive loop, as it used to!
- a little more testing and I can close
bug 614175: infinite panic loop if bochsrc buggy
- modified: main.cc gui/siminterface.h gui/wxmain.cc
and into wxmain.cc, like other actions.
- set a default siminterface callback for the whole application, which is used
whenever the simulator is not running. This is important when the wx code
calls simulator or param code and triggers a BX_PANIC or something.
The default callback is responsible for displaying error messages which
appear while reading the bochsrc, for example.
- move the implementation of BX_SYNC_EVT_LOG_ASK and BX_ASYNC_EVT_LOG_MSG
into a separate function OnLogMsg(). In the future, OnLogMsg() may be called
from the application default callback on errors.
