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
(TODO: find a way to call plugin_fini() for non-core devices if plugins are
disabled)
- set the device pointers back to stubs after unloading plugins
- added debug message "Exit" in all device plugin destructors
* 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
Linux detect it correctly. This changes has no effect on r/w operations.
- data rate select register partially implemented
- register reset fixes and additions
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- the option floppy_command_delay is obsolete now, since all floppy delays are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.
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
- improved debug messages for i/o port reads and writes
* support for XDF images added
* floppy controller should hang if media not present
* rombios has to reset the floppy controller after read/write failure
bochs.h already not include iodev.h which reduces compilation dependences for almost all cpu and fpu files, now cpu files will not be recompiled if iodev includes was changed
- evaluate_media(): new variable 'raw_floppy' indicates raw floppy access on win32
- evaluate_media(): try to read the first sector determine the presence of the
floppy media (raw access on win32)
