'sdl'. Now both display libraries can be compiled together and used with the
'show ips' feature. TODO: win32-specific 'show ips' timers for 'rfb' and 'wx'
the existing runtime dialog ('textconfig' is still available)
- removed notify callback redirection from sdl.cc and win32.cc
- removed win32 specific code from textconfig.cc
- fixed parent window for folder selection dialog
- minor size changes in start menu dialog
- Added configure option to compile in GUI frontend for Bochs internal
debugger, to enable configure with --enable-debugger-gui option. The GUI
debugger frontend is enabled by default with Bochs internal debugger.
If needed to compile without GUI debugger (in case of compilation issues) use --disable-debugger-gui
There is a trick in MSVC is to turn on the -Gr compiler switch which tells MSVC to compile all functions using fastcall calling convention. This way you don't have to edit each function declaration. But certain functions must NOT be fastcall, and those are callbacks from Windows which are defined either as cdecl or stdcall. The entry point main() also has to remain cdecl.

#1079240 by Ben Lunt. There are still some problems:
- PS/2 mouse is always present (some code to emulate a disconnected mouse needed)
- PS/2 wheel mouse doesn't work properly
- serial wheel mouse detected as a standard mouse and doesn't work at all
Description from the author:
This API allows framebuffer device plugins to draw directly on to the
GUI's tile buffer and hence eliminates the need to memcpy(3C) tiles to
an intermediate buffer. Functions like update_hardware_cursor function
are rendered unnecessary as framebuffer device plugins can now draw the
full range of host colours. svga_cirrus will fallback to calling
graphics_tile_update without a hardware cursor if the GUI doesn't support
the new API. This patch includes implementations of graphics_tile_info,
graphics_tile_get, and graphics_tile_update_in_place (the new API) for SDL
and X11.
- new graphics update API implemented in wx and rfb
- common update functions for guis without support for the new API added (should
be removed after implementing the new API in all display libraries)
bochs.h already not include iodev.h which reduces compilation dependences for almost all cpu and fpu files, now cpu files will not be recompiled if iodev includes was changed
(based on a patch from Christopher Nelson <paradox@BBHC.ORG>)
* the win32 gui changes the bitmap settings using the bpp argument
* added stubs for all guis except win32
* descriptions of function dimension_update() updated
font usage)
- horizontal and vertical pel panning in text mode implemented (without windows
fonts only)
- separate bitmap for the textmode cursor no longer necessary
- text_update(): unused variable new_start removed
compile time. The old version used this fonts for char heights smaller 14.
If the Windows fonts are enabled, the font heights 12, 14 and 16 are used.
These features are not available in that case:
* charmap change
* char width switch 8/9
* horizontal and vertical pel panning
If the Windows fonts are disabled, the changeable guest font is used and all
implemented features are available. This is the default setting.
TODO: implement horizontal and vertical pel panning
FIXME: Should we add a bochsrc option to control the font usage?
- invalidate character at previous and new cursor location before entering the
update loop
- cursor drawing moved into the update loop
- variables for previous cursor position renamed
in text mode. The new variables 'text_rows' and 'text_cols' are used in the
text_update() function.
- desriptions of the functions text_update() and dimension_update() updated
and implemented in SDL
* sequencer controller register 0x01 bit 0 controls the width of the characters.
This value is used to calculate the screen width.
* attribute controller register 0x10 bit 2 controls the appearance of graphics
characters (ASCII 0xC0 - 0cDF). A change of this value forces a charmap update
to rebuild the font bitmaps.
* the SDL display library uses the new feature described above
* the other display libraries recalculate the screen width, since they are using
a fixed font width of 8 for now.
- VGA: attribute controller register 0x10 bit 2 (enable_line_graphics) does not
switch the palatte in CGA mode
DEV_kbd_gen_scancode() is called instead of DEV_kbd_put_scancode(). This
change enables the support for different scancode sets. The win32 scancodes
are now converted to bx_key values.
the icon problem on Win2000. RegisterClassEx() would be required if we want
to specify a special mini icon.
- the win32 gui now uses the new function/macro DEV_vga_actl_pal_idx() to
determine the text mode colors.
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_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.

'char_changed'. These variables are currently only used by the win32 gui for
the update of the font bitmaps. SDL and wxWindows do not use the variables
since they are using the charmap data directly
- free text snapshot memory when the user has cancelled the dialog
- write text snapshot file in binary mode (disables the LF -> CRLF conversion
in cygwin)
set_text_charbyte()
- vga: store the address of the active charmap in the new variable
charmap_address
- vga: text mode hack removed. The write modes, operations and masks must be
used in text mode too.
- sdl: clear_screen() is not necessary when the charmap has changed
- win32: update only the changed font bitmaps before drawing the text
X windows, wxWindows. Each platform has its own way of returning
a variable length string, and its own rules about how you're supposed
to dispose of the string. Now all platforms do the same thing: they
allocate a Bit8u buffer with C++ "new" and copy the clipboard data in,
then release the clipboard data in the platform-specific correct way.
The Bit8u buffer is sent to the keyboard code, which frees it with
delete [] when finished.

bitmaps. The bochs window now consists of 3 windows: the main window and
it's child windows simulation window and toolbar window.
Changes:
- new windows "mainWnd" and "simWnd" replace the old "hwnd"
- moved the functions of the old window procedure to the new ones
- toolbar functions added in create_bitmap(), headerbar_bitmap() and
replace_bitmap()
- function show_headerbar() no longer needed (must be present for
compatibility)
- a few variables for the headerbar changed or removed
- bitmap and headerbar variables now initialized in specific_init()
- The emulated vga card issues a dimension_update() using the real
screen dimensions and the real font height.
- The gui selects a font with the requested height or it recalculates
the screen height if the font height is not available.
- The text_update() function uses a new variable 'ncols' instead of the
fixed value of 80 for the number of text columns.
I have tested the changes with X11/Linux, SDL, wxGTK and win32. The changes
in the other guis are not tested yet.
