code and the generic USB stuff. Up to now, in plugin mode each host controller
staticly links all this stuff with the plugin library. So it existed twice and
e.g. it wasn't possible to create a unique serial number for disks/cdroms
connected to different HCs. Some other sanity checks could be added now, too.
- Added a register mechanism for the USB device init function in the main
devices code.
- TODO: Some other device plugins could be fixed the same way: network devices
(sharing ethernet modules), harddrive & usb_msd (sharing hdimage and
cdrom)
the SF patch #1539417, but rewritten from scratch (patch too old). Differences
to the original version:
* internal parameter name "readonly"
* update parameter if floppy image is readonly
* wxWidgets support
* documentation updates
* no specific toolbar buttons
keyboard and usb_hid code to use them
- removed keyboard handling from the USB host controller code
- removed no longer needed USB stubs from the devices code
- converted removable mouse variables to a structure
by Ben Lunt will be tested and merged soon)
- renamed specific pciusb stuff to 'usb_uhci' (files, objects)
- minor USB-related changes
- TODO: changes in siminterface and bochsrc options
bochsrc option (e.g. biosdev, speaker, gameport)
* the "unmapped device" is now an optional plugin, the builtin default handlers
no longer cause panics
* speaker stub calls the related gui methods for beep on/off
* load all optional plugins before starting init of core plugins
* initialize plugin system before parsing bochsrc and command line
* pass previous value to bx_param_string_c handler
* load / unload plugin in bx_param_string_handler()
* handle user plugins after optional ones in plugin device init, reset and
save/restore functions
* added new siminterface method unregister_user_option()
* removed first version of config option handling for user plugins
* added new parameter subtree for user-defined options
* added new bx_list_c method remove()
* removed unused bx_devmodel_c method init_mem()
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
The connection status is now only controlled by the USB port options (TODO:
device change support at runtime)
- a connected USB mouse now has the priority when sending mouse data from the
gui to the emulated mouse device.
done by the object destructor (changes in cmos, hard drive and keyboard)
- bx_unload_plugins() now deletes the devmodel object in non-plugin mode
- CMOS device now prints the time on exit in human-readable format
unregister_irq(). This is required since there are some devices that don't
use a string constant for the handler name.
- replaced true / false by portable 0 / 1 values.
(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
- added exit() method to the devmodel object for devices that need to do special
cleanups on exit. Device plugins should call this method from their plugin_fini()
function. If Bochs is compiled without plugin support, for non-core plugins
the exit() method is called directly from bx_unload_plugins().
- exit() method implemented in the keyboard device
- wx "Show Keyboard" feature now only appear when the wxdebug keyboard subtree
is not empty
- cpu cleanup must be done before the devices cleanup
- moved PCI chipset dump call to the devices exit method
* don't initialize cpu specific parameters for the wx debugger if they already
exist
* separate siminterface method init_save_restore() added
* old wx specific handling in quit_sim() removed
* new bx_list_c method clear() deletes all parameters from the list
* moved devices cleanup code from the pc_system to a new devices method exit()
* pc_system init code now sets ticksTotal to 0
* register_state() will be called after init() and registers the device members
required for save/restore
* before_save_state() can do some work before the device state is saved by the
siminterface
* after_restore_state() can do some work after the device state has been
restored (updating dependant stuff)
- BM-DMA base address set to 0xc000 at reset (shoud be done by the PCI BIOS)
- BM-DMA status register write messages changed to BX_DEBUG
- fixed an MSVC warning in the harddrive code
#1079240 by Ben Lunt. There are still some problems:
- PS/2 mouse is always present (some code to emulate a disconnected mouse needed)
- PS/2 wheel mouse doesn't work properly
- serial wheel mouse detected as a standard mouse and doesn't work at all
* up to 5 slots can be specified with the 'i440fxsupport' config option
* the pci slot number are hardwired to pci device numbers
* the 'devfunc' value is returned the calling device (useful for multi-function
devices)
* the core of the i440FX chipset is hardwired to pci device 1 + 2; usb is still
optional and appears at device 1, function 2
- ne2k: enable pci features if connected to a pci slot
- ne2k: asic data port supports 32-bit access if ne2k-pci is active
- pci2isa: improved error messages for ELCR1 and ELCR2
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
This is necessary for devices with different i/o port masks.
- BX_MAX_IO_DEVICES increased to 30
- io_len mask fixed and unnecessary io_len checks removed in
* biosdev.cc
* cmos.cc
* dma.cc
Unallowed cases are now handled in devices.cc and cause a BX_ERROR.
- io_len mask fixed and unnecessary io_len checks removed in
* devices.cc
* extfpuirq.cc
* gameport.cc
* ne2k.cc
* pit.cc
* pit_wrap.cc (i/o register function calls replaced by DEV_* macro calls)
- TODO: implement this in all other devices
You can now choose for each disk on the ata interfaces the
disk mode, between :
- flat : one file flat layout
- concat : multiple files layout
- external : developer's specific, through a C++ class
- dll : developer's specific, through a DLL
- sparse : stackable, commitable, rollbackable
- vmware3 : vmware3 disk support
- undoable : flat file with commitable redolog
- growable : growing file
- volatile : flat file with volatile redolog
- z-undoable : gziped flat file with commitable redolog
- z-volatile : gziped flat file with volatile redolog
A new "bxcommit" utility can merge commitable redologs to
flat images.
- it works only on x86 with gcc2.95+
- uses the GCC function atribute "regparm(n)" to declare that certain
functions use the register calling convention
- performance improvement is about 6%

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.
palette - it's an index to the attribute controller palette index.
The new function get_actl_palette_idx() now returns the real DAC index.
The guis sdl, wx and x11 are using the new function. TODO: Fix this bug in
all other guis.
- moved ne2k presence check to devices.cc
- added special make rules for the ne2k and the lowlevel network support
- added macro for the debug feature of the ne2k
