cd4d17a363 - min and max in shadow params were broken recently when I changed the
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.

c07f5836f3 - move definition of bx_address earlier, just after the Bit32u and Bit64u
types are defined.  This should ensure that bx_address is defined by
  the time it's needed.

3183ab7102 Added some preliminary configure and config.h stuff for
SSE/SSE2 for Stanislav.  Also, some method prototypes and
  skeletal functions in access.cc for read/write double quadword
  features.

Also cleaned up one warning in protect_ctrl.cc for non-64 bit compiles.
  There was an unused variable, only used for 64-bit.

261badee5a Added a couple macros which expand on GCC to __attribute__ directives
to give the compiler some hints:

    BX_CPP_AttrPrintf(formatArg, firstArg)
    BX_CPP_AttrNoReturn()

The first is to tell the compiler that a function receives printf-like
  arguments so it can do some smart argument checking w.r.t. the
  format string.  The 2nd tells the compiler that the function does
  not ever return; it's not used yet, but I'd like to use it on
  exception() after we fix the situation of it returning for debugging.

I fixed one parameter mismatch in cpu/ by deleting a deprecated
  debug print statement.  There are several other mismatches in
  other code modules.

47f2e7c404 Got rid of the KPL64Hacks macro. The fixes below eliminated it.
Created 64-bit versions of some branch instructions and
  changed fetchdecode64.cc to use them instead.  This keeps the
  #ifdef pollution down for 32-bit code and made fixing them
  easier.  They needed to clear the upper bits of RIP for
  16-bit operand sizes.  They also should not have had a protection
  limit check in them, especially since that field is still
  32-bit in cpu.h, so there's no way to set nominal 64-bit values.
  The 32-bit versions were also not honoring the upper 32-bits
  of RIP.

  LOOPNE64_Jb
  LOOPE64_Jb
  LOOP64_Jb
  JCXZ64_Jb

Changed all occurances of JCC_Jw/JCC_Jd in fetchdecode64.cc to
  use JCC_Jq, which was coded already.  Both JMP_Jq and JCC_Jq are
  now fixed w.r.t. 16-bit opsizes and upper RIP bit clearing.

c3a74d4da0 Integrated patches/patch.promise-dc2300-vlbide from Christophe Bothamy.
From his patch file text:

  > This patch adds Promise DC2300 VLB IDE Support.
  > You may find msdos and win95 drivers on the net. Look for
  > P2300W95.ZIP and DC2300VLBIDEver260b.ZIP.
  >
  > The good news is that now win95 natively sees my cdrom,
  > and that the disks are not in msdos compatibility mode any more.
  >
  > The bad news is that it works only for the first ata interface.
  >
  > I tested that patch on msdos and win95 only.
  >
  > Some info on VLB IDE can be found at http://ryston.cz/petr/vlb/

I got Win95 running with 32-bit paging/filesystem using the
  recommended driver and these patches.  Since the patches did
  such a good job bracketing code modifications with a #define,
  they might as well become part of the current CVS code.

281e62d8b1 I integrated my hacks to get Linux/x86-64 booting. To keep
these from interfering from a normal compile here's what I did.
In config.h.in (which will generate config.h after a configure),
I added a #define called KPL64Hacks:

  #define KPL64Hacks

*After* running configure, you must set this by hand.  It will
default to off, so you won't get my hacks in a normal compile.
This will go away soon.  There is also a macro just after that
called BailBigRSP().  You don't need to enabled that, but you
can.  In many of the instructions which seemed like they could
be hit by the fetchdecode64() process, but which also touched
EIP/ESP, I inserted a macro.  Usually this macro expands to nothing.
If you like, you can enabled it, and it will panic if it finds
the upper bits of RIP/RSP set.   This helped me find bugs.

Also, I cleaned up the emulation in ctrl_xfer{8,16,32}.cc.
There were some really old legacy code snippets which directly
accessed operands on the stack with access_linear.  Lots of
ugly code instead of just pop_32() etc.  Cleaning those up,
minimized the number of instructions which directly manipulate
the stack pointer, which should help in refining 64-bit support.

91fd4b3745 Added new configure option --enable-host-specific-asms, so the
user can turn on/off use of native host specific inline asm
  statements.  By default, this option is enabled, so you only
  need it to disable inline asms in your compile for now.

Currently only on x86+GCC environments, will inline asm()
  statements be used.  Eventually, other platforms could specify
  some asm()s; probably for endian issues such as byte-swapping
  and unaligned memory accesses.  On x86, there are some inline
  asm()s which do the arithmetic EFLAGS processing so that the
  lazy flags handling is somewhat bypassed.  Eventually, I'll
  add more, at least for the more common instructions.  This
  adds a little extra performance.

249131fbed I added a support function to osdep.
The function gets the real time in useconds and puts it in
a Bit64u.  This function is defined when:
BX_HAVE_REALTIME_USEC is 1.

Right now, BX_HAVE_REALTIME_USEC is defined to be BX_HAVE_GETTIMEOFDAY
and bx_get_realtime64_usec is defined in terms of gettimeofday().

However, it could be defined in terms of any other method of obtaining
the current time accurate to the usecond.  That is why I moved the
function to osdep and added the new define.

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.

08576b24be I implemented Global pages. Though, I haven't tested them. :^)
You need to use '--enable-global-pages' to configure in support.
If you have something to boot that uses them, give them a
spin.  Really the were introduced for PPro and above, but
I haven't put in any limits.  CPUID and CR4 report the proper
bits when configured, regardless of --enable-cpu-level at the
moment.

Patch name: patch.wx-show-cpu2
Author: Bryce Denney
Date: Fri Sep  6 12:13:28 EDT 2002

Description:

Second try at implementing the "Debug:Show Cpu" and "Debug:Show
Keyboard" dialog with values that change as the simulation proceeds.
(Nobody gets to see the first try.)  This is the first step toward
making something resembling a wxWindows debugger.

First, variables which are going to be visible in the CI must be
registered as parameters.  For some variables, it might be acceptable
to change them from Bit32u into bx_param_num_c and access them only
with set/get methods, but for most variables it would be a horrible
pain and wreck performance.

To deal with this, I introduced the concept of a shadow parameter.  A
normal parameter has its value stored inside the struct, but a shadow
parameter has only a pointer to the value.  Shadow params allow you to
treat any variable as if it was a parameter, without having to change
its type and access it using get/set methods.  Of course, a shadow
param's value is controlled by someone else, so it can change at any
time.

To demonstrate and test the registration of shadow parameters, I
added code in cpu/init.cc to register a few CPU registers and
code in iodev/keyboard.cc to register a few keyboard state values.
Now these parameters are visible in the Debug:Show CPU and
Debug:Show Keyboard dialog boxes.

The Debug:Show* dialog boxes are created by the ParamDialog class,
which already understands how to display each type of parameter,
including the new shadow parameters (because they are just a subclass
of a normal parameter class).  I have added a ParamDialog::Refresh()
method, which rereads the value from every parameter that it is
displaying and changes the displayed value.  At the moment, in the
Debug:Show CPU dialog, changing the values has no effect.  However
this is trivial to add when it's time (just call CommitChanges!).  It
wouldn't really make sense to change the values unless you have paused
the simulation, for example when single stepping with the debugger.

The Refresh() method must be called periodically or else the dialog
will show the initial values forever.  At the moment, Refresh() is
called when the simulator sends an async event called
BX_ASYNC_EVT_REFRESH, created by a call to SIM->refresh_ci ().

Details:
- implement shadow parameter class for Bit32s, called bx_shadow_num_c.
  implement shadow parameter class for Boolean, called bx_shadow_bool_c.
  more to follow (I need one for every type!)
- now the simulator thread can request that the config interface refresh
  its display.  For now, the refresh event causes the CI to check every
  parameter it is watching and change the display value.  Later, it may
  be worth the trouble to keep track of which parameters have actually
  changed.  Code in the simulator thread calls SIM->refresh_ci(), which
  creates an async event called BX_ASYNC_EVT_REFRESH and sends it to
  the config interface.  When it arrives in the wxWindows gui thread,
  it calls RefreshDialogs(), which calls the Refresh() method on any
  dialogs that might need it.
- in the debugger, SIM->refresh_ci() is called before every prompt
  is printed.  Otherwise, the refresh would wait until the next
  SIM->periodic(), which might be thousands of cycles.  This way,
  when you're single stepping, the dialogs update with every step.
- To improve performance, the CI has a flag (MyFrame::WantRefresh())
  which tells whether it has any need for refresh events.  If no
  dialogs are showing that need refresh events, then no event is sent
  between threads.
- add a few defaults to the param classes that affect the settings of
  newly created parameters.  When declaring a lot of params with
  similar settings it's more compact to set the default for new params
  rather than to change each one separately.  default_text_format is
  the printf format string for displaying numbers.  default_base is
  the default base for displaying numbers (0, 16, 2, etc.)
- I added to ParamDialog to make it able to display modeless dialog
  boxes such as "Debug:Show CPU".  The new Refresh() method queries
  all the parameters for their current value and changes the value in
  the wxWindows control.  The ParamDialog class still needs a little
  work; for example, if it's modal it should have Cancel/Ok buttons,
  but if it's going to be modeless it should maybe have Apply (commit
  any changes) and Close.

746f09b427 There's a bug in the repeated IO & mem copy speedups. I
added --enable-repeat-speedups with default to disabled.
Reconfigure/recompile and the speedup code will be #ifdef'd
out for now.  It manifested as junk written to the VGA screen
while booting/running Windows.

Also made some more mods to the main cpu loop.  Moved the
handling of EXT/errorno outside the main loop, much like
the extra EIP/ESP commits were moved, for a little better
performance.

I changed the fetch_ptr/bytesleft method of fetching to
a slightly different model, which calculates a window
for which EIP will be valid (land on the current page),
and a bias which when applied to EIP will be from
0..upper_page_limit.  Speed is about the same for either
method, but a pseudo-op/threaded-interpreter will plug
in better with this and be faster.

3a5f338419 Integrated patches for:
- Paging code rehash.  You must now use --enable-4meg-pages to
    use 4Meg pages, with the default of disabled, since we don't well
    support 4Meg pages yet.  Paging table walks model a real CPU
    more closely now, and I fixed some bugs in the old logic.
  - Segment check redundancy elimination.  After a segment is loaded,
    reads and writes are marked when a segment type check succeeds, and
    they are skipped thereafter, when possible.
  - Repeated IO and memory string copy acceleration.  Only some variants
    of instructions are available on all platforms, word and dword
    variants only on x86 for the moment due to alignment and endian issues.
    This is compiled in currently with no option - I should add a configure
    option.
  - Added a guest linear address to host TLB.  Actually, I just stick
    the host address (mem.vector[addr] address) in the upper 29 bits
    of the field 'combined_access' since they are unused.  Convenient
    for now.  I'm only storing page frame addresses.  This was the
    simplest for of such a TLB.  We can likely enhance this.  Also,
    I only accelerated the normal read/write routines in access.cc.
    Could also modify the read-modify-write versions too.  You must
    use --enable-guest2host-tlb, to try this out.  Currently speeds
    up Win95 boot time by about 3.5% for me.  More ground to cover...
  - Minor mods to CPUI/MOV_CdRd for CMOV.
  - Integrated enhancements from Volker to getHostMemAddr() for PCI
    being enabled.

26385f2866 - I've added lots of comments in siminterface.h, and tried to clean up
the terminology a bit.  In particular, the term "gui" has started
  to mean different things in different contexts, so I've defined
  some more specific names for the parts of the user interface, and
  updated comments and some variable names to reflect it.  See
  siminterface.h for a more complete description of all of these.

    VGAW: VGA display window and toolbar buttons, the traditional Bochs
      display which is ported to X, win32, MacOS X, etc.  Implemented
      in gui/gui.* and platform dependent gui/*.cc files.
    CI: configuration interface that lets the user change settings such
      as floppy disk image, ne2k settings, log options.  The CI consists
      of two parts: configuration user interface (CUI) which does the
      actual rendering to the screen and handles key/mouse/menu events,
      and the siminterface object.
    CUI: configuration user interface.  This handles the user interactions
      that allow the user to configure Bochs.  To actually change any
      values it talks to the siminterface object.  One implementation of
      the CUI is the text-mode menus in gui/control.cc.  Another
      implementation is (will be) the wxWindows menus and dialogs in
      gui/wxmain.cc.
    siminterface: the glue between the CUI and the simulation code,
      accessible throughout the code by the global variable
        bx_simulator_interface_c *SIM;
      Among other things, siminterface methods allow the simulator to ask the
      CUI to display things or ask for user input, and allows the CUI
      to query and modify variables in the simulation code.


    GUI: Literally, "graphical user interface".  Until the configuration menus
      and wxWindows came along, everyone understood that "gui" referred to the
      VGA display window and the toolbar buttons because that's all there
      was.  Now that we have the wxWindows code, which implements both the VGAW
      and the CUI, while all other platforms implement only the VGAW, it's not
      so clear.  So, I'm trying to use VGAW, CI, and CUI consistently since
      they are more specific.
    control panel: This has been used as another name for the configuration
      interface.  "control panel" is also somewhat unspecific and it sounds
      like it would be graphical with buttons and sliders, but our text-mode
      thing is not graphical at all.  I've replaced "control panel" with
      "configuration interface" wherever I could find it.  In configure script,
      the --disable-control-panel option is still supported, but it politely
      suggests that you use --disable-config-interface instead.
- clean up comments in siminterface,wx* code
- add comments and examples for bx_param_* and BxEvents
- remove some obsolete stuff: notify_*_args,
  bx_simulator_interface_c::[sg]et_enabled() methods
- in siminterface.cc, move a few bx_real_sim_c methods to where they belong,
  with the rest of the methods.  No changes to the actual methods.
- remove some DOS ^M's which crept in and confused my editor.

fda1b874e9 Check in FETCHDECODE Caching, with changes.
Specific changes from the patch:

1.) renamed fdcache_eip to fdcache_ip, as it is using
the RIP instead of the EIP.

2.) added a Boolean array fdcache_is32 which uses is32
to determine icache hits.  Otherwise we could run 32-bit
code as 16-bit or vice versa.

d1ef29dc6e - Added a biosdev "pseudo device" to handle the log output of the rombios and vgabios :
. ports 0x0400 0x0401 and 0xfff0 : rombios
  . ports 0x0500 0x0501 and 0x0502 : vgabios
  The rombios log output was previously handled by the unmmapped device

9a177ba518 - add configure test for ethertap. On systems which have a header file
called <linux/netlink.h> the ethertap module will be defined.  If other
  OSes turn up that also have ethertap, we can change the test.
- in eth_tap.cc, I replaced the calls to GPL code from maconlinux with
  my own stuff.

556a8fa8f8 - commit patch.check-platform. For full details, pull up the patch itself
and look at the description at the top.  Here's an intro.

  This patch makes significant changes to the configure script.  It adds the
  lines AC_CANONICAL_HOST and AC_CANONICAL_TARGET which detect the OS and
  processor type.  The configure script, knowing the OS and processor type, can
  then make intelligent decisions about which CFLAGS are needed and what is the
  default GUI for that platform.  One of the goals of this patch is to make it
  so that on all supported platforms, "configure;make" will compile cleanly.
  Configure detects the target platform, but it can be overridden by using
  --target=___.  This is important when using one platform to generate
  Makefiles and header files for another platform.  See config.guess script for
  the exact details of platform naming.

  The defaults that are currently implemented in the modified configure script
  include:
    If platform is windows* or winnt*, use win32 gui.
    If platform is cygwin*, use win32 gui and compile with
       "-mno-cygwin -DWIN32".
    If platform is macosx* or darwin*, use carbon gui and compile
       with "-fpascal-strings -fno-common -arch ppc -Wno-four-char-constants
       -Wno-unknown-pragmas -Dmacintosh"
    If platform is macos, use macos gui.
    If platform is beos, use beos gui.
    If platform is amigaos, use amigaos gui.
    Otherwise, use X windows gui.

ee6b54f395 - distinguish between WIN32 the platform and WIN32 the gui library.
use #if defined(WIN32) to determine if you are on that platform
  and #if BX_WITH_WIN32 to determine if you are using that gui.

57273620e6 Added an experimental realtime PIT to the mix.
This is basically the opposite of the slowdown timer.  Instead
of trying to keep the PIT ticks in sync with bochs time, we
keep them in sync with REAL time.  This is bad because it creates
unreproducible fails, but it's good if you want to run bochs at
maximum speed on your machine.  However, bochs will take all of
the available resources from the machine also.

DO NOT use this with the slowdown timer.  Results would be
unpredictable.

2cd62e75c8 - Dave enabled the E9 hack in config.h.in, but it had no effect. The correct
way is to make the configure.in default to turning it on.  The value in
  config.h.in will be replaced by configure anyway.

bf286c20ac - configure and makefile changes for AmigaOS port. Now configure
--with-amigaos is allowed and sets up the makefiles correctly.  It
  defines a symbol called BX_WITH_AMIGAOS, which should be used in
  #if..#endif constructs that are specific to amigaos.
- if --enable-cdrom is used with --with-amigaos, the cdrom_amigaos.o
  object file will be added to CDROM_OBJS in the iodev makefile.

ec0fbf18bc - convert nearly all bx_options to parameter form. All options that have
been converted into parameters temporarily have the letter "O" appended
  to their name.  I don't want to keep it this way, but it has helped
  in the conversion process because the compiler refuses to compile the
  old uses of the name.  Before I started using the "O" trick, there were
  many bugs like this:   if (bx_options.diskc.present) {...}
  This was legal with the new parameters, but it was testing whether the
  parameter structure had been created, instead of testing the value of
  the present parameter.  Renaming present to Opresent turns this into
  a compile error, which points out the incorrect use of the param.
- the "--disable-control-panel" no longer works, I'm afraid.  I can no
  longer support this and continue progress.

1ae66aeeb6 - added empty stubs for serial_raw. To try it out, define USE_RAW_SERIAL
in config.h and add serial_raw.o to the makefile in the iodev directory.

f822257511 - there were cases where BX_APIC_SUPPORT were used and others where
BX_SUPPORT_APIC were used.  To follow the pattern used by other
  names like this, I changed them all to BX_SUPPORT_APIC.
  Thanks to Tom Lindström for chasing this down!

8b7fbca53e - more work on text-mode control panel. Now the control panel starts before
the simulation begins, to give you a chance to choose between bochsrcs,
  choose the boot disk, etc.

565fa8ea8e - another speed boost: when not using SMP, use
BX_CPU_C bx_cpu;
     BX_MEM_C bx_mem;
  and when more than one processor, use
     BX_CPU_C    *bx_cpu_array[BX_SMP_PROCESSORS];
     BX_MEM_C    *bx_mem_array[BX_ADDRESS_SPACES];
  The changeover is controlled by BX_SMP_PROCESSORS, but there are only
  a few code changes since nearly all code uses the BX_CPU(n) and BX_MEM(n)
  macros.
- This turns out to make a 10% speed difference!  With this revision,
  the CVS version now gets 95% of the performance of the 3/25/2000
  snapshot, which I've been using as my baseline.

e61d00351f - merged BRANCH-smp-bochs into main branch. For details see comments
in BRANCH-smp-bochs revisions.
- The general task was to make multiple CPU's which communicate
  through their APICs.  So instead of BX_CPU and BX_MEM, we now have
  BX_CPU(x) and BX_MEM(y).  For an SMP simulation you have several
  processors in a shared memory space, so there might be processors
  BX_CPU(0..3) but only one memory space BX_MEM(0).  For cosimulation,
  you could have BX_CPU(0) with BX_MEM(0), then BX_CPU(1) with
  BX_MEM(1).  WARNING: Cosimulation is almost certainly broken by the
  SMP changes.
- to simulate multiple CPUs, you have to give each CPU time to execute
  in turn.  This is currently implemented using debugger guards.  The
  cpu loop steps one CPU for a few instructions, then steps the
  next CPU for a few instructions, etc.
- there is some limited support in the debugger for two CPUs, for
  example printing information from each CPU when single stepping.

a04c65e642 - new, partially implemented, lines in .bochsrc allow run-time choice of
what action to take on panic, error, info, and debug.  The lines don't
  have any effect quite yet because of an initialization order problem
  with the logfunctions.

e363f402ca - This implements a solution that lets any GUI take over handling of any
signal.  First, selection of the GUI should cause BX_GUI_SIGHANDLER to
  be defined in config.h.in.  Then, the GUI should define member functions
    Bit32u get_sighandler_mask ();
    void sighandler (int sig);
  The mask function returns a bitfield where one bit corresponds to each
  signal.  For any signal whose bit is set to 1 in the return value of
  get_sighandler_mask, the gui will control that signal.  When the signal
  arrives, bx_gui.sighandler(sig) will be called by bx_signal_handler,
  instead of the default behavior of that signal.

d2203e662f - added most of Todd's "term mode" patch. I didn't apply all of the signal
handling part, so I need to figure out how control-C's and control-Z's
  will get mapped into keystrokes.

e2a0ce5c03 - Applied patch based on one by Roland Mainz, 4/1/2001.
Panic-is-fatal patch, allows user to choose whether to crash on bx_panic()
  or just print a warning.  The default behavior is still to crash.

4e04f4cb58 - change all inline declarations to one of two macros: BX_C_INLINE or
BX_CPP_INLINE.  Then in config.h.in you can define these two as you
  wish.

a6ad4c3903 - Applied const64bit patch:
For compilers (such as Microsoft VC++) which don't allow "LL" after a
  constant to make it 64-bit, this patch declares all such constants as
  BX_CONST64(value).  Then in config.in, a switch called
  BX_64BIT_CONSTANTS_USE_LL controls whether the macro puts the
  LL's in or not.  Configure sets the macro, if you're on a platform
  that can run such things.
