- TODO: add save/restore support, use Bochs function for host to little endian
data conversion, timers of networking modules 'vnet' and 'slirp' should use
the device speed instead of fixed 10 MBit
and the supported ethernet modules
- renamed eth.* files to netmod.*
- pseudo-device plugin implementation similar to 'soundmod'
- TODO: move sound, net and usb stuff to a separate subdirectory of iodev
with the host time. After using a runtime config dialog or save and restore
simulation, this behaviour makes the PIT clock and the VGA update timer
running way too fast until it's back in sync. Now the elapsed time is stored
in the variable 'real_time_delay' and it is used to let the PIT clock run at
realtime speed, even if it is out of sync.
Sebastian Herbszt). TODO list:
- modify LGPL'd VGABIOS to make it work with SeaBIOS
- modify Bochs BIOS to set up the legacy address 0xc0000
- implement PCI ROM support in the cirrus device
- move load_ROM calls to the display adapter code to handle the ISA case
The ACPI support is always automatically compiled in if PCI is compiled in.
The ACPI still could be disabled using .bochsrc 'plugin_ctrl' option.
Updated CHANGES and docs as well.
DAC2 is sent to the lowlevel sound module. DAC1 and sound input (ADC) are not
yet supported. Also unsupported: CODEC (mixer), UART (MIDI) and legacy support.
Sound module selection in configure script now no longer depends on SB16 and
uses autodetection only.
- fixed segfault when saving bochsrc
--enable-vbe is now deprecated and the symbols BX_SUPPORT_VBE and
BX_SUPPORT_PCIVGA have been removed. To enable VBE support, the bochsrc option
"vga: extension=" must be set to "vbe". If PCI is present, you can assign the
"pcivga" device to a PCI slot.
* added new "pseudo device" for the USB device control (init, send message)
* moved register_state() call from the hubs to the common device init code
- fixed unresolved symbols in usb_msd code
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)
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
* '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
