* 'usb_uhci' bochsrc option replaces 'usb1'
* minor changes in the USB code
* removed old VBE i/o port registration (they were incompatible with USB)
* updated FSF address
- fixed saving user plugin options
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
- exit() method sets the number of registered timers back to 1 (or 2 if APIC
is present)
- fixed some parameter types for save/restore
- debug message for timer registration added
- slowdown timer: exit method added to reset the timer id
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)
Averything that required cpu.h include now has it explicitly and there are a lot of files not dependant by CPU at all which will compile a lot faster now ...
- sb16 parameters stored in the device class and runtime parameter handler added
- wx: ParamDialog can currently handle only dependency lists of bool parameters
correctly (TODO: add support for numeric parameters)
- disable usb options if not compiled with usb support
- usb and network dependency list created with menu->clone()
- load usb plugin only if at least one hub is present
- remaining options prepared for rewrite
- proposed parameter tree updated
- bx_init_options(): local variables cleanup
- hide floppy devtype parameter (floppy media type change support not yet complete)
- wx: menu order changed
- keyboard.cc: removed obsolete FIXME
- proposed parameter tree updated
- save pcidev config line if enabled
- load pcidev plugin if requested
- pci parameter dependencies improved
- textconfig: show the title of a disabled submenu
dummy interface are now disabled if the extension isn't set to "vbe"
- writing charmap data in graphics mode now supported (SF patch #1059199)
- fixed set_ask_format() for the mouse type option
- ne2k and sb16 config lines now support the parameter "enabled=0|1"
- config parser code for ne2k and pnic now working the same way
- ne2k enable option now present in config menu / dialog
* PCI initialization and configuration space handling added
* ASIC data port now supports 32-bit r/w if PCI is present
* PCI device will be enabled if the requested base address is >= 0x1000
- ne2k: 8390 command register is now present on all pages
- ne2k: some panics changed to errors, debug messages improved
- PCI host bridge is now a core plugin (if enabled) and initialized earlier
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
- pit: and time0: options are still supported but deprecated
- warn when parsing deprecated directives
- fix wrong number of ata_device_translation_names
- still to do:
- setting time0 to utc is not yet supported
- the man page, user guide and .bochsrc still need to be updated
with the new options
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
- 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%
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.
- 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
"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.
