parameter values associated with the dialog and updated the wxWindows
controls. At the time I didn't realize that I was overriding
wxWindow::Refresh() which repaints the window. Later, I renamed the method
to CopyParamToGui() to make it more clear, but many of the callers in
wxmain.cc continued to call Refresh(), which now reverted to the parent class
wxWindow::Refresh(). Since there was no compile error I didn't notice for a
while, but it caused the ParamDialogs to repaint themselves constantly but
never actually change their values. This is now fixed by changing those
method calls to CopyParamToGui().
started using a wxTimer to trigger the redraws. Now instead of calling
MyPanel::OnPaint directly, I call Refresh() instead. This makes the Windows
display work correctly.
I'm not sure why this wasn't needed before, but after switching to
wxWindows 2.3.3 it seems to be important.
- in a wxLogDebug() call I was trying to pass a struct instead of a string.
Fixed that.
- hardcode BX_HAVE_GETTIMEOFDAY=0 if cross compiling for VC++
(this part hasn't been tested)
- modified files: configure configure.in config.h.in iodev/pit_wrap.cc
so frequently.
Coded asm() statements for INC/DEC_ERX() instructions.
Cleaned up the iCache a litle including a bug fix. The
generation ID was decrementing the whole field including
some high meta bits. That could roll over after 1 Billion
cycles. I know only decrement if the field is valid, to
save the write.
I implemented inline functions which can serve the value of
the arithmetic flags if they are cached, and redirect to
the lazy_flags.cc routines if not.
Most of this was just prep work for adding more asm() statements
for native eflags processing when on x86.
'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)
- pci2isa prefix changed to "P2I"
- device name changed to "PIIX3 PCI-to-ISA bridge"
- added more default values to the reset() function
- added stubs for i/o mapped registers
- array pci_conf[] is now a part of the structure s
a precursor to making it a runtime option. I'm not
sure how to do this, but it should be trivial. All it
would take is adding the option and changing the
macro for BX_USE_REALTIME_PIT to point to that option.
also extended by the REX.B field on Hammer) is passed to instructions.
I rearranged the bxInstruction_c to free up a field to be used
to pass this info when mod-rm bytes are not used. This got rid
of the ugly ((i->b1 & 7) + i->rex_b) code.
Probably shaved just a very little run time off Hammer emulation,
and even less on x86-32. The resultant is a little cleaner anyways.
and I could never explain it. The problem was that in keyboard.cc it
included "math.h" with quotes instead of <math.h> with less than/greater
than, so gcc -MM didn't realize it was a system header.
- MyPanel::blankCursor
- MyFrame::panel
- AdvancedLogOptions::action (2d array of wxChoice *'s)
- ParamDialog::idHash, ParamDialog::paramHash, and ParamStructs
- file dialog in BrowseTextCtrl
- fix illegal use of a wxObject. I had been clearing the ParamStruct
with memset(), but I forgot that ParamStruct was a subclass of wxObject
so I was trashing the wxObject fields too! Instead I created a
ParamStruct constructor that clears the pointers to NULL.
- comment out debug output from AdvancedLogOptionsDialog::SetAction
- modified files: gui/wx.cc gui/wxdialog.cc gui/wxdialog.h
gui/wxmain.cc gui/wxmain.h
- put off some log related features until later
- advanced log options and debug log are done, so I removed them from the list
- added some wxWindows coding hints I found on usenet
interface) by using get/set_default_log_action. This has very minimal effect
on the behavior of the text config interface.

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
- LogOptionsDialog: show the "no change" option. When options other than
"no change" are selected, set both the default log action and the
specific log action for all devices.
- AdvancedLogOptionsDialog: store the wxChoice*'s in a 2d array since I
have to refer to them later.
- since both the log options and advanced log options dialogs needed to
create many wxChoices using similar rules, I moved the creation code
into a utility function makeLogOptionChoiceBox.
- I finally discovered the wxADJUST_MINSIZE option to wxSizer::Add(),
which solves some layout problems that I was having with wxChoices.
With this setting, the wxChoice will automatically grow to the size of
the largest string that can be selected.
- improve sizing of the scrollWin according to the desired size of the panel
that contains all the wxChoices.
- add sketches for proposed dialog that combines both LogOptionsDialog and
AdvancedLogOptionsDialog using tabs

in cpu.cc out of the main loop, and into the asynchronous
events handling. I went through all the code paths, and
there doesn't seem to be any reason for that code to be
in the hot loop.
Added another accessor for getting instruction data, called
modC0(). A lot of instructions test whether the mod field
of mod-nnn-rm is 0xc0 or not, ie., it's a register operation
and not memory. So I flag this in fetchdecode{,64}.cc.
This added on the order of 1% performance improvement for
a Win95 boot.
Macroized a few leftover calls to Write_RMV_virtual_xyz()
that didn't get modified in the x86-64 merge. Really, they
just call the real function for now, but I want to have them
available to do direct writes with the guest2host TLB pointers.
but if you hand edit cpu/cpu.h, and change BxICacheEntries,
you can try different sizes. I'll make this more flexible
with configure. For now, use "--enable-icache" with no parameters.
- Modified fetchdecode.cc/fetchdecode64.cc just enough so that
instructions which encode a direct address now use a memory
resolution function which just sticks the immediate address
into rm_addr. With cached instructions we need this.
