32-bit CPU using Bochs binary compiled with x86-64 support.
The commit also fixes some init.cc issues with initialization of SYSCALL/SYSRET MSR in AMD hosts and also includes code reorg.
with --enable-avx option. When compiled in, AVX still has to be enabled
using .bochsrc CPUID option. AVX2 FMA instructions still not implemented.
- Added support for Bit Manipulation Instructions (BMI) emulation. The BMI
instructions support can be enabled using .bochsrc CPUID option.
Selecting CPU MODEL from .bochsrc automatically chooses real HW CPUID and also configures Bochs emulator to emulate this specific CPU including all its features only.
Supported CPUs to choose from:
core2_extreme_x9770
corei7_sandy_bridge_2600K
p4_prescott_celeron_336
'vga_update_interval' option. The screen update frequency is still based on
the emulated clock unless the realtime sync is enabled with the 'clock' option.
TODO: rewrite the virt_timer code to support realtime screen updates
independent from 'clock' setting.
- fixed changing parameter 'update_freq' at runtime (timer object and blink counter)
* moved runtime handlers for cdrom from config.cc to the device object
* cd media status variable is now always of type bx_bool
* changed obsolete gui names like "cdromD" to "cdrom1"
* TODO: implement new runtime config mechanism similar to USB
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.
recent version of Slirp with Debian patches applied. On a Linux host the
guest OS can access the internet without running Bochs with root privileges.
TODO:
* rewrite the DHCP part of eth_vnet.cc that it can be used here, too
* Slirp doesn't compile on 64-bit Linux with GCC 4.5
* WIN32 is not supported yet
connected device. For now this feature is only used by the 'disk' device to
specify an alternative redolog filename of some image modes.
- added new methods set_option() and timer() to the base class usb_device_c.
The timer() method is periodicly called from the HC's frame timer code.
- moved runtime device change stuff from the parameter handler to the end of
timer() methods of all hubs. This makes sure that all parameters for the
device have been set at connect time. TODO: this technique could also be used
for the floppy and cdrom media change.
- several fixes related to configurable geometry (some more tests required)
- skip MBR and boot sector image files when reading directory (still unused)
- support overriding cylinder value with 0 in the command line
- don't return failure value when reading unused sectors
- increment buffer pointer when reading more than one sector
- siminterface: added helper method hdimage_get_mode()
- moved hdimage related stuff from harddrv.cc to the hdimage code
- changed hdimage related names
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
the default Bochs method using the CTRL key and the middle mouse button there
are now the choices CTRL+F10 (like DOSBox) and CTRL+ALT (like QEMU).

compatible with the win32 ParamDialog
* reorganized runtime parameter lists (usb and cdrom setup in device init)
* renamed win32 StartMenuDialog() to MainMenuDialog() and some related name
changes
* added runtime support to the MainMenuDialog
- win32 start/runtime menu: set keyboard focus to the start/continue button

and value must be != "none" to enable dependents)

the existing runtime dialog ('textconfig' is still available)
- removed notify callback redirection from sdl.cc and win32.cc
- removed win32 specific code from textconfig.cc
- fixed parent window for folder selection dialog
- minor size changes in start menu dialog
enable the floppy drive without media and status specified
- simplified parsing of floppy bochsrc options
- default media status for floppy drives set to BX_EJECTED
- cdrom drives no longer need the path to be set in bochsrc (empty path had
disabled the device in the previous version)
- simplified ATA device setup in bochsrc parser
non-empty path
- floppy devtype parameter now uses CMOS values and drive type names
- related changes in the floppy code
- simplified floppy parameter handlers
- some floppy parameter label changes
- added enable handler for the floppy path parameter
- update dependent params after setting the dependent bitmap of enum parameter
- win32paramdlg: fixed setting parameters at runtime
- fixed win32 ParamDialog return value for close/cancel
- runtime dialog for the first cdrom drive on win32 is now created as a win32
ParamDialog (removed old cdrom1 dialog stuff)
- minor fixes in x11 string dialog for the cdrom path & status case
dependency list processing, enum parameter support)
- bx_param_enum_c: added argument for the default value of the dependent bitmaps
to set_dependent_list()
- bx_param_num_c: dependent_list is now a protected member of the object to make
it accessible for the enum specific dependency code
- config.cc: ata parameter dependency rewrite to avoid multiple dependencies
- config.cc: added missing dependency for SB16 parameter list
Bit64u value with the "enable bitmap" (e. g. bit #0 is the enable value for
the first item of the dependent list). TODO: use this feature in win32 and wx
dialogs
- ata drive type and loader hack parameters now using the enum dependent list
- avoid multiple dependencies in the SB16 config menu
- added file extension support for bx_param_filname_c
- fixed showing of tab control child lists

- on win32 use the ParamDialog instead of textconfig submenus (TODO: gui dialog
replacement for the start menus

* ported the basic functionality of the wx ParamDialog to win32
* moved AskFilename() function to the new file
* win32ParamDialog() now used for the external USB hub (if present)
* TODO: with some extensions it might be possible to use it for all runtime

* updated FSF address
- fixed saving user plugin options
* 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()

for trailing null byte when using strncpy)
* length of initial string should not be larger than maxsize
* reset() method now uses set(initial_val)
* cut model string on boot screen if larger than 36 characters to make one
"ata" message fit in one line
* config parameter for model string needs one more byte
* harddrive: terminate model string with null
* "pipe-server" (win32 only): It makes bochs a named pipe server so other
application can communicate with it using pipes API. Useful e.g. for remote
kernel debugging.
* "pipe-client" (win32 only)
* "socket-server": for the use with gdb
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
