Make save/restore default feature, the configure option for save/restore removed from configure script and save/restore made available forever. All code now assume it is exists. Bochs save/restore tree previosly called "save_restore" renamed to "bochs" tree and it will be havily used everywhere, starting from save/restore and ending by various bochs debugger functions. I am going to rework debugger code to get rid of debug CPU access functions and use this "bochs" param tree instead
- removed obsolete structures and members from the USB code
- removed mouse type 'usb' (USB mouse and tablet override selected mouse type
when connected)
- user doc: mention vmware 4 disk image support
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).

You can now choose for each disk on the ata interfaces the
disk mode, between :
- flat : one file flat layout
- concat : multiple files layout
- external : developer's specific, through a C++ class
- dll : developer's specific, through a DLL
- sparse : stackable, commitable, rollbackable
- vmware3 : vmware3 disk support
- undoable : flat file with commitable redolog
- growable : growing file
- volatile : flat file with volatile redolog
- z-undoable : gziped flat file with commitable redolog
- z-volatile : gziped flat file with volatile redolog
A new "bxcommit" utility can merge commitable redologs to
flat images.

Comment from the author:
Attached is a "patch" file detailing what you need to do
to add USB support (UHCI only for now) to your existing
Bochs (2.0.xx) source code.
I use Win32 and VC++ but the source and modifications
should be platform and compiler independant.
Please let me know if this patch some how breaks the
build process of your compilation (Bochs 2.0.0 or above
only).
I would also like any feedback on how this code works
(or doesn't work) on your platform and within your
images. If you explain in as much detail as you can on
how it did or did not work, I will try to add to the source
to help it work on all platforms and images.

- for MacOSX/Carbon, if you start the app by double clicking in the finder,
there is no text console. So in logfunctions::fatal(), display the
final message in a Carbon dialog instead of using fprintf.
- in the text-mode config interface, return an error code if the
user tries to use the text menus when there's no text console.
Back in bxmain() this error code causes a panic
"Bochs needed the text console, but it was not usable"
- if a config file was not found, normally we turn off quick start
and drop into the text menus. However in the no-console case the
text menus won't work, so we added a panic: Unable to start Bochs
without a bochsrc.txt and without a text console. This is a much
more useful error than the generic one above.
- removed ensure_text_console() which was making matters worse instead
of better.

completely ignored and Bochs has always been returning 0. Now Bochs should
exit with the proper exit code.
- implementation: BX_EXIT(exitcode) calls SIM->quit_sim(exitcode).
quit_sim stores the exit code in the SIM object, then uses longjmp
to unwind the stack and return to main(). main() calls
SIM->get_exit_code() to retrieve the exit code and returns it.
- If you are wondering why we don't just call exit(exitcode), it is
because in the wxWindows interface all of the CPU simulation runs as one
thread while the user interface runs as another thread. With the longjmp
technique the simulation thread ends cleanly and it is possible to
start a new simulation thread without making a new process.
eject, insert, eject, etc. several extra times before allowing you to
actually change the CD. The extra insert/eject cycles were coming from the
param handlers for cdrom status and for the cdrom pathname. To fix this, I
changed wxdialog.cc and textconfig.cc to only call set() on parameters if
they are different from the original value. Now it generally does what you
would expect.
- to change physical CD: change the Bochs CD status to "ejected". On some OSes
that will actually eject it, but on others it will simply close the file so
that the eject button will actually work. Then put the new CD into the
drive, and change the Bochs CD status to "inserted".

the first hard drive or first cdrom drive no matter where they are found.
Now the wxWindows interface recognizes this fact. It allows you to
select HD boot if there is a hard drive in any ATA location, and
select CDROM boot if there is a cdrom in any ATA location.
- this fixes bug [ 616139 ] wx: boot hd/cd must be in ata0 interface

gui/siminterface.cc gui/siminterface.h gui/wxmain.cc
This fixes bug #614724: SDL can get stuck in full-screen mode, and provides
a framework for fixing the problem on other full-screen display libraries
such as term, svga, etc.
- add virtual method bx_gui::set_display_mode(mode) which can be overridden
by each display library class, if appropriate. This method is primarily
used when you run Bochs full screen, to tell the gui to switch from full
screen back to a mode where you can use the text console.
- There are two display modes: config and simulation. The mode is changed to
config mode during logfunctions::ask, during the runtime configuration menu,
and before displaying a debugger prompt. It is changed back to simulation
mode whenever instructions are running.
- Instead of being called directly through the global bx_gui pointer, the
bx_gui_c::set_display_mode() method is almost always accessed through
siminterface, like this:
SIM->set_display_mode (DISP_MODE_CONFIG);
SIM->set_display_mode (DISP_MODE_SIM);
Of course siminterface just passes the call on to bx_gui::set_display_mode().
I added it to siminterface so that the config interfaces could call it.
(They don't #include bochs.h so they can't access bx_gui.)

there is one more option in the configuration file "debugger_log"
if the debugger is compiled in, all debugger output will be also
written to this file. Note: wxWindow config interface is not updated yet
- 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.

New behaviour is:
. No command line arg (user want to load or create a new conf file)
-> no .bochsrc is loaded
-> defaults to "2. Read options from..."
. command line arg -q (user want to quick start from .bochsrc)
-> .bochsrc is loaded
-> if found Run the simulation
-> if not found defaults to "2. Read options from..."
. command line arg -f (user want to edit a conf file)
-> conf file is loaded
-> if found defaults to "3. Edit options"
-> if not found defaults to "2. Read options from..."
. command line arg -qf (user want to quick start from a conf file)
-> conf file is loaded
-> if found Run the simulation
-> if not found defaults to "2. Read options from..."
. 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
- 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.

- 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.
- modified: gui/siminterface.h gui/siminterface.cc
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
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".

- 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

time, so I've tried to improve it. Now the logfunctions class has a
static field default_onoff[] which represents the default actions for
each kind of log message. Default_onoff[] is initialized with static
data so it should be valid by the time it's used. This can be reached by
static accesors logfunctions::set_default_action and
logfunctions::get_default_action. It seemed appropriate to put the defaults
inside the logfunctions class, rather than in bx_options or siminterface.
However, to make them accessible to the config interface, I added similar
methods in siminterface that map to the accessors in logfunctions.
- logio.cc had two different definitions of LOG_THIS for different halves
of the file, which was ugly and confusing. (LOG_THIS is needed for BX_INFO,
BX_DEBUG, etc.) I removed the first definition and fixed the minor compile
problems that ensued. In the initializers for iofunctions, everything
is complicated because of the unpredictable order that constructors get
called. They must use this->log to print things, because genlog hasn't
been initialized yet.
- now if SIM->set_log_action(int mod, int level, int action) is called
with mod<0, it sets the action for all modules/devices instead of just one.
