- siminterface: ask_filename() uses the prompt for the parameter name
- wx: missing title of the CMOS dialog added
- floppy path parameter names changed (used by win32config)
- user shortcut parameter description added
- pit: and time0: options are still supported but deprecated
- warn when parsing deprecated directives
- fix wrong number of ata_device_translation_names
- still to do:
- setting time0 to utc is not yet supported
- the man page, user guide and .bochsrc still need to be updated
with the new options
- add handlers called when a parameter is enabled or disabled.
This is useful for parameter dependent on another, that may
not wish to be enabled when its father parameter is enabled.
* changed all %ll format descriptions to FMT_LL macro so that
Microsoft Visual C works correctly (it uses %I64)
* missing type conversions added
* cdrom.cc: variable types for win32 fixed
* removed some unused variables in eth_win32.cc and harddrv.cc
* added missing includes in make_cmos_image.c and niclist.c
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.

- 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".

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 #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 .bochsrc is loaded
-> defaults to "2. Read options from..."
. command line arg -q (user want to quick start from .bochsrc)
-> .bochsrc is loaded

-> 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

- 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.

constructors around. The min,max that were being passed to the parent
class constructor had junk in them. In config.h.in, I defined the minimum
and maximum values for each integer datatype so now we pass correct
min and max values to the parent class. These replace the BX_MAX_[U]INT
and BX_MIN_[U]INT values.

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.

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".

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.
- Features :
. number of active channels defined at boot-time config
. new options in bochsrc
. up to 8 devices support (disks or cdroms)
. up to 4 cdrom devices can be changed at runtime config

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.
- modified: bochs.h logio.cc main.cc gui/siminterface.cc gui/siminterface.h

printed to stderr in the text debugger. Also allows the user to
type (text) debugger commands directly, which also appear in the log.
- all text output in the debugger now passes through dbg_printf()
(used to be fprintf to stderr) so that in wxWindows I can redirect
it all to the wxWindows debug log screen. Added debug_fputs to
siminterface which actually sends the text to the GUI by creating
a BX_ASYNC_EVT_DBG_MSG event.
- changed prefix and msg fields of BxLogMsgEvent to const char *,
and also in args of logmsg method of siminterface.
- don't trap SIGINT in wxWindows. There are other ways to stop execution.
Also, signal handling with multiple threads is very strange and different
on different platforms.
- minor changes to fix gcc -Wall warnings in dbg_main.cc
- add a new boolean parameter BXP_DEBUG_RUNNING that tells if the debugger is
running freely or not. This is used by the wxWindows GUI to enable or
disable certain choices.
- CpuRegistersDialog has continue,stop,step buttons. When the sim is running
freely, I disable continue and step, and enable stop. When the sim stops
to wait for the user, I disable stop and enable continue and step. The
change of enables used to be triggered by actually pressing the button,
but then if you started/stopped the simulation in some other way (typing
in debug log window) the enables were never changed. Now the enables are
controlled by the value of BXP_DEBUG_RUNNING, which is set by the debug code
itself, and the buttons are enabled at the right time.
- ParamDialog::Refresh() is now virtual so that child classes can redefine
its refresh behavior.
- in safeWxStrcpy, force the last element of the array to be a 0, since
I noticed that strncpy is not guaranteed to terminate the string!

Bochs debugger. The Bochs debugger calls SIM->debug_get_next_command() which
does not return until a debugger command is found. The siminterface sends an
synchronous event to the wxWindows thread with a blank to be filled in with a
debugger command. wxWindows fills in the blank and sends the synchronous
event back, and the Bochs debugger interprets it as if it was typed on
the command line. For the long term I haven't decided whether to stick with
sending text strings vs. some other method.
- so far the wxWindows debugger consists of one big dialog box that shows
all the standard registers, and a working Continue, Stop, and Step button.
- modify ParamDialog so that it is more useful as a base class, by moving
some things to protected members&fields, separating out functionality
that is most likely to be replaced into virtual functions, and making it
generally more flexible. The new CpuRegistersDialog is based on
ParamDialog.
- in wxdialog.cc, continue the convention of using wxID_HELP, wxID_OK,
wxID_CANCEL, etc. for the id's of buttons, instead of wxHELP, wxOK, etc.
which are intended to be ORred together in a bit field.
- cpu/init.cc: put ifdefs around DEFPARAMs for flags in configurations
where they don't exist. Add an eflags shadow parameter that represents all
of the bits of eflags at once. There are also boolean shadow params for
each bit.

length. (The first guinea pig is the 2-bit IOPL field in eflags.)
Also it can have a pointer to a Bit8u, Bit16u, Bit32u and signed
equivalents and do the right thing.
- add lots more CPU fields as parameters: EBP ESI EDI ESP, all segment regs,
LDTR, GDTR, eflags, DR*, TR*, CR*. These are all visible on a
ridiculously tall dialog box that will one day become the debugger.
