ed36bc11f0 - sync up control.cc (text mode config interface) with wxmain.cc (wxWindows
interface) by using get/set_default_log_action.  This has very minimal effect
  on the behavior of the text config interface.

eca3ef17dc - How to handle default log options has been somewhat confused for a long
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

a33f144f6c - implement behavior of the AdvancedLogOptionsDialog
- 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

9b02229b84 Removed defunct options from configure.in (for dynamic translation
and old style fetchdecode cache).  Removed generations of
dynamic/Makefile.  Upgraded my autoconf to 2.50 to get rid

402d02974d Moved the EFLAGS.RF check and clearing of inhibit_mask code
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.

0cd7346b9c - Added an instruction cache. Size is fixed for the moment,
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.

721f89b77b - forward changes of the active charmap to the gui with the new function
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

d8c27b4f83 - add AdvancedLogOptionsDialog. It's not connected to actual parameters
yet, since I've been just working on the layout at first.  The main

c278349cdf - in wxWindows, hide mouse cursor when mouse is captured, to avoid the

24d88d2d28 - implement mouse in wxWindows interface
- All mouse events in the VGA window go to MyPanel::OnMouse.  Middle mouse
  button and F12 both toggle mouse capture.  OnMouse queues an event
  for the simulation thread to process.  The simulation thread calls
  bx_devices.keyboard->mouse_motion() when it sees the event on the queue.
- add IFDBG_VGA around some display debug code.  All wx mouse debug code
  is controlled by IFDBG_MOUSE.

0a5ce87b15 - now instead of having the simulation thread send repaint messages to
the wxwindows thread, it just sets a boolean flag needRefresh.  Meanwhile, a
  wxTimer running in wall clock time (as opposed to sim time) triggers a
  repaint only if the the boolean is true.
- now MyRefresh is implemented by just setting needRefresh=true.
- make graphics_tile_update call MyRefresh.
- make dimension_update call MyRefresh.

4e51dcae40 Converted all the remaining available separate fields in bxInstruction_c
to bitfields.  bxInstruction_c is now 24 bytes, including 4 for
the memory addr resolution function pointer, and 4 for the
execution function pointer (16 + 4 + 4).

Coded more accessors, to abstract access from most code.

Kevin Lawton
6723ca9bf4 Moved more separate fields in the bxInstruction_c into bitfields
with accessors.  Had to touch a number of files to update the
access using the new accessors.

Moved rm_addr to the CPU structure, to slim down bxInstruction_c
and to prevent future instruction caching from getting sprayed
with writes to individual rm_addr fields.  There only needs to
be one.  Though need to deal with instructions which have
static non-modrm addresses, but which are using rm_addr since
that will change.

bxInstruction_c is down to about 40 bytes now.  Trying to
get down to 24 bytes.

4e091e37ea - the constructors for BX_MEM_C did not always init vector and actual_vector
to NULL.  If actual_vector points to junk when alloc_vector_aligned
  is called, it will try to free the junk, leading to memory corruption
  or crashes.

15a3cbc35f - make cpu_param_handler compile with SMP enabled. Unfortunately it will
read all param values from CPU #0.  The only solution I can come up with
  is to change the siminterface handler function interface to pass a void*
  to the callback function.  I'll take care of it eventually.

3591c3297b - add several new categories of test compile configurations, which

07b0df2a8a Updated accessing of modrm/sib addressing information to
use accessors.  This lets me work on compressing the
size of fetch-decode structure (now called bxInstruction_c).

I've reduced it down to about 76 bytes.  We should be able
to do much better soon.  I needed the abstraction of the
accessors, so I have a lot of freedom to re-arrange things
without making massive future changes.

Lost a few percent of performance in these mods, but my
main focus was to get the abstraction.

274ce4cd55 This patch applies on top of Christophe Bothamy's 4ata-channels patch.
I'm keeping a separate patch in case Christophe wants to make revisions
to his patch without my changes getting in the way.

I have just been working on the configuration interface part, for
example making it so that when you disable the ata[0123] channel, all the
devices controlled by that channel will be disabled as well.  I haven't
gotten around to the wxWindows part, but these changes will make the
wxWindows work much easier.  I will update this patch as my work progresses.

ad8bb1023b - move the dependent_list structure up the hierarchy to bx_param_num_c,
instead of bx_param_bool_c.  There are several cases where I need an
  enum to enable/disable some fields, and this change should allow
  that.

3d4210fd3f Got rid of a couple fields in BxInstruction_t that were

to be more compressed.  Over time, I'm going to reduce
it further, for use with future accelerations.
