f25a3df39b - added minimal USB support (patch from Ben Lunt <fys@cybertrails.com>, updated
and improved by Christophe Bothamy and Volker Ruppert)

Comment from the author:

Attached is a "patch" file detailing what you need to do
to add USB support (UHCI only for now) to your existing
Bochs (2.0.xx) source code.

I use Win32 and VC++ but the source and modifications
should be platform and compiler independant.

Please let me know if this patch some how breaks the
build process of your compilation (Bochs 2.0.0 or above
only).

I would also like any feedback on how this code works
(or doesn't work) on your platform and within your
images. If you explain in as much detail as you can on
how it did or did not work, I will try to add to the source
to help it work on all platforms and images.

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.

  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.

c818baa0c9 - modified every I/O device so that it will not re-register its timers
if init() is called a second time.  This allows me to restart a

ee47fabac0 Committed new bochs internal timers (in pc_system.{cc,h}.
These seem to be working better, are a more simple design,
  easier to understand, and AFAIK don't have race conditions
  in them like the old ones do.

Re-coded the apic timer, to return cycle accurate values
  which vary with each iteration of a read from a guest OS.
  The previous implementation had very poor resolution.  It
  also didn't check the mask bit to see if an apic timer
  interrupt should occur on countdown to 0.  The apic timer
  now calls its own bochs timer, rather than tag on the
  one in iodev/devices.cc.

I needed to use one new function which is an inline in
  pc_sytem.h.  That would have to be added to the old pc_system.h if
  we have to back-out to it.

Linux/x86-64 now boots until it hits two undefined opcodes:

  FXRSTOR (0f ae).  This restores FPU, MMX, XMM and MXCSR registers
    from a 512-byte region of memory.  We don't implement this yet.

  MOVNTDQ (66 0f e7).  This is a move involving an XMM register.
    The 0x66 prefix is used so it's a double quadword, rather than
    MOVNTQ (0f e7) which operates on a single quadword.

  The Linux kernel panic is on the MOVNTQD opcodes.  Perhaps that's
  because that opcode is used in exception handling of the 1st?

  Looks like we need to implement some new instructions.

83c9d266d0 Added a field on register_timer() so that a name identifying the
requesting source can be registered as well.  Otherwise, there
  is no way to know which source modules are requesting

414e97bc32 Enhanced the repeat IO accelerations (enabled by --enable-repeat-speedups)
to request bulk IO operations to IO devices which are bulk IO aware.
Currently, I modified only harddrv.cc to be aware.  I added some
fields to the bx_devices_c class for the IO instructions to
place requests and receive responses from the IO device emulation.
Devices except the hard drive, don't monitor these fields so they
respond as normal.  The hard drive now monitors these fields for
bulk requests, and if enabled, it memcpy()'s data straight from
the disk buffer to memory.  This eliminates numerous inp/outp calling
sequences per disk sector.

I used the fields in bx_devices_c so that I would not have to
disrupt most IO device modules.  Enhancements can be made to
other devices if they use high-bandwidth IO via in/out instructions.

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.

c7c9cc2430 - DMA register and unregister functions for DMA channels added and macros for
DMA functions defined. Most of the changes are based on the "bochs sync"
   version of plex86. Here is the list of changes:

  * register/unregister functions for DMA channels added. The DMA controller
    can use the DMA read/write handlers of registered devices directly.
  * "hardwired" code in dma.cc removed
  * all DMA related code in devices.cc and iodev.h removed
  * DMA related code in pc_system.* removed except HRQ handling
  * macros for DMA functions defined in bochs.h
  * floppy and SB16 code modified to use the changes described above

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

d71c73ed88 - rename TIMER_DELTA to to BX_IODEV_HANDLER_PERIOD. Now that it's a global
define, I wanted it to be a little more descriptive.

ad072e2bc6 - implementation of the edge triggered IRQ mode
- new functions raise_irq() and lower_irq()
- all trigger_irq() / untrigger_irq() calls are replaced by the new functions
- REMARK: timer IRQ handling is not correct but it works
- TODO: IOAPIC IRQ handling needs to be changed

9aa7a88028 Lots of timer stuff.
Fixed a "feature" in pc_system.cc with setting timers to small values
that can cause bochs to hang.

Significantly improved the performance of the new PIT.
It's probably ready to become the default now.

Added a preliminary implementation of the slowdown timer
that Bryce and I had talked about.

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!

2bbb1ef8eb strip '\n' from BX_{INFO,DEBUG,ERROR,PANIC}
don't need it, moved the output of it into the general io functions.
saves space, as well as removes the confusing output if a '\n' is left off

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.
