071c5c1a26 A lot of changes but everything is really trivial.
Make save/restore default feature, the configure option for save/restore removed from configure script and save/restore made available forever. All code now assume it is exists. Bochs save/restore tree previosly called "save_restore" renamed to "bochs" tree and it will be havily used everywhere, starting from save/restore and ending by various bochs debugger functions. I am going to rework debugger code to get rid of debug CPU access functions and use this "bochs" param tree instead

9340f3b3f8 - partial sync with BRANCH_SAVE_RESTORE_3 (hardware save/restore not present yet)
* changed data format of text files for save/restore (looks like C/C++ structures,
    similar to the format used in old save/restore branches)
  * don't set the initial value of shadow bool parameters
  * don't set the initial value of bool parameters twice
  * cpu/init.cc: missing #undef added
  * ne2k.cc: variable tx_timer_active was never set to 1 (type now bx_bool)
  * floppy.cc: missing initialization of the 'eot' array in reset() added
  * pic.h: type of member 'byte_expected' changed to Bit8u
  * pit_wrap.h: unused members removed

2005-11-16 21:21:35 +00:00
Volker Ruppert
e0f02463f9 - the step delay for the recalibrate and seek commands is now calculated from the
number of steps to do, the step rate time and the date rate
- the option floppy_command_delay is obsolete now, since all floppy delays are
  based on the hardware specs. The usage of this option caused a warning now.

b88facfb66 - more accurate timing for reading data using a motor speed of 300 RPM. This is
important at boot time if the user wants to control the boot process.
  TODO:
  * implement timing for write and format commands
  * more accurate timing for seek, recalibrate and maybe others
  * raw floppy access slows down the emulation, use separate threads (???)
- irq line goes low with when reading the first result byte
- the drive status bits are only modified after reading the first result byte
- handling of floppy command 'sense interrupt status' simplified

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.

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
  simulation (wxwindows interface only) without restarting the whole
  application.
- modified: iodev/*.cc
2002-10-06 19:04:47 +00:00
Bryce Denney
f54551717e - include <windows.h> in bochs.h whenever WIN32 is defined. This is required
so that windows types can be used in fields, for example in cdrom.h:
    #ifdef WIN32
      HANDLE cdrom_interface::hFile;
    #endif
- since every file includes bochs.h, I removed includes of <windows.h>
  everywhere else

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
  suspect frequencies which are too high.

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.

c3cda0a919 - separation of floppy device type and media type started. This feature needs
more work in the floppy and bios code.
- floppy and cdrom entries in the runtime config menu can be disabled if the
  drive wasn't defined in bochsrc or start menu
- floppy variable "initial_status" and cdrom variable "inserted" renamed to

88f0e1b73f - init(): initialize media type for all 4 drives
- init(): set the initial status to BX_EJECTED if evaluate_media() fails
- don't modify the DOR when a drive > 1 is selected
- floppy command 'get status' now recognizes the head field
- floppy command 'recalibrate': don't set cylinder to 0 before completion
- floppy command 'sense interupt status' does not clear status register 0
- floppy command 'configure': more detailed BX_DEBUG messages
- floppy command 'read ID' does not modify status register 0
- floppy read/write commands: set the error bit in status register 0 if media
  is not present
- better detection of not existing drives in some commands: check the media type
  of the selected drive instead of the drive select value
- behaviour of floppy commands 'recalibrate' and 'seek' changed:
  * drive is busy in the execution phase, but not the controller
  * replaced the panic by setting the error status if drive is not existing
- evaluate_media(): set the media type even if device/file is not present

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

328bd4fb84 - fixed the behaviour of some floppy commands (Windows 95 driver works now)
* diskette controller data register returns last result if no new data
    is available
  * reset will be activated when the reset bit is changed to normal operation
  * reset sets the error bits in status register 0
  * write access to port 0x3f4 will cause a BX_ERROR now
  * unsupported and invalid floppy commands are setting the error status bit
    'invalid command' - BX_PANIC not necessary
  * flag FS_MS_DIO is not set while a floppy command is pending
  * floppy command 'specify': cause a BX_ERROR when non-DMA mode is selected
  * floppy command 'sense interrupt status' returns an error is no interrupt
    is pending
  * floppy command 'read ID' sets the 'busy' flag and returns no data if the
    motor is not on
  * removed SIMX86 section (not defined in bochs)
  * define variable 'sTemp' for win32 only

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.
