8db0a2b001 Replaced the plugin init / fini functions with one single function called
plugin_entry(). The additional boolean argument "init" is used to select the
requested action. The entry points still have unique names for compatibility
with the "non-plugin" compilation. Added macros for setting up these names
(e.g. PLUGIN_ENTRY_FOR_MODULE for device plugins).

bda6a2a6de Speaker beep methods should only be called in PIT mode 3 (square wave generator).
Added speaker handler to send OUT line change to new speaker method set_line().

c10e8feea6 Added support for driving the speaker line directly with the speaker gate, but
the square wave generator disabled. This feature has been used by old demos and
games to play digitized sound before soundcards with DSP became popular.

89654a4beb Prepared devices and timer code for HPET support
- PIT / CMOS: added methods to control IRQ generation (for HPET legacy mode).
- Added method for activating timer with nanosecond value.
- Removed unused declaration in the keyboard code.
- TODO: virtual timer code also needs to handle nanosecond values.

76b54ecb61 Renamed bx_pci_device_stub_c to bx_pci_device_c and derive it now from class
bx_devmodel_c. The early version of the combined vga / svga_cirrus code
required the now obsolete implementation. Some related cleanups in the
devices code.

59f5a03af6 Rewrite of the virtual timer code to support both modes at the same timer.
The timers now have a new member 'realtime' and they are driven by the
selected engine. The VGA update timer and the status LED timer now always use
the realtime mode, but the PIT and CMOS RTC depend on the clock options.

bcdcf42bdd - io_len mask in i/o register functions implemented (1 = 8bit, 2 = 16bit, 4 = 32bit).
Unallowed cases are now handled in devices.cc and cause a BX_ERROR.

  * ne2k.cc
  * pit.cc

- TODO: implement this in all other devices

79831381de - fix compile problem in old PIT 2002-10-26 03:57:19 +00:00
Bryce Denney
cec9135e9f - Apply patch.replace-Boolean rev 1.3. Every "Boolean" is now changed to a
"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.

5e520261db Add plugin support to Bochs by merging all the changes from the
BRANCH_PLUGINS branch!

Authors:
  Bryce Denney
  Christophe Bothamy
  Kevin Lawton (we grabbed a lot of plugin code from plex86)
Testing help from:
  Volker Ruppert
  Don Becker (Psyon)
  Jeremy Parsons (Br'fin)

The change log is too long to paste in here.  To read the change log, do
  cvs log patches/patch.final-from-BRANCH_PLUGINS.gz

All the changes and a detailed description are contained in a patch
called patch.final-from-BRANCH_PLUGINS.gz.  To look at the complete
patch, do
  cvs upd -r1.1 patches/patch.final-from-BRANCH_PLUGINS.gz

Then you will have a local copy of the patch, which you can gunzip and
play with however you want.

7fdc7303c2 - add "void reset(unsigned type)" method to every I/O device.
Some devices already had one.  Some I had to add an empty one.
  I did a little cleaning of init() methods to make them more uniform
  but generally I left them alone.
- I also put these exact diffs into a patch "patch.iodev-add-reset"
  in case I want to revert these changes for some reason, for example
  if they break an old patch.  It should be deleted after a while.

fc0ee2dc3e Added compiler define to use the new PIT.
Also added a hack to keep the OpenBSD timer problem from filling the log.

The new PIT seems to work, but until some
enhancements are made to the way the timers
and devices.cc work, it'll be slower than
the old one.

bdb89cd364 merge in BRANCH-io-cleanup.
To see the commit logs for this use either cvsweb or
cvs update -r BRANCH-io-cleanup and then 'cvs log' the various files.

In general this provides a generic interface for logging.

logfunctions:: is a class that is inherited by some classes, and also
.   allocated as a standalone global called 'genlog'.  All logging uses
.   one of the ::info(), ::error(), ::ldebug(), ::panic() methods of this
.   class through 'BX_INFO(), BX_ERROR(), BX_DEBUG(), BX_PANIC()' macros
.   respectively.
.
.   An example usage:
.     BX_INFO(("Hello, World!\n"));

iofunctions:: is a class that is allocated once by default, and assigned
as the iofunction of each logfunctions instance.  It is this class that
maintains the file descriptor and other output related code, at this
point using vfprintf().  At some future point, someone may choose to
write a gui 'console' for bochs to which messages would be redirected
simply by assigning a different iofunction class to the various logfunctions
objects.

More cleanup is coming, but this works for now.  If you want to see alot
of debugging output, in main.cc, change onoff[LOGLEV_DEBUG]=0 to =1.

d12a76d30b - Applied patch: pit-panic.
The 82c54 model (pit.cc) implements timer modes 0, 2, and 3 in its handler
  functions, without caring which timer number is involved.  However, the
  I/O write code that sets the mode is inconsistent.
    Timer 0 can be set to modes 0,2,3 only.
    Timer 1 can be set to mode 2 only.
    Timer 2 can be set to mode 2,3 only.
  From a quick reading of an 8254 datasheet, I can't see any reason to
  restrict which timer can be in which mode, so I think it's correct to
  allow ALL timers to go into ALL modes that are implemented.
