- Fixed ne2k parameter save function.
- For backward compatibility, card #0 defaults to PCI if the ne2k is assigned
to at least one PCI slot.
- The "bootrom" parameter is only valid for the PCI card type.
old SF patches this solution is compatible with the plugin architecture. The
ne2k plugin is loaded only once and a new ne2k_main_c object creates up to 4
ne2k device objects depending on the config. The new ne2k parameter "card"
specifies the zero-based card number to configure. If not given, the default
is card #0 for compatibility. The new ne2k parameter "type" specifies the bus
it is connected to ("isa" or "pci"). Card #0 defaults to PCI, the others to
ISA. In the PCI slot configuration the ne2k device can be used multiple times
if more than one card is configured.

- removed SMF stuff for ne2k
- always convert device prefix to uppercase (ne2k uses NE2K0 ... NE2K3)

This code is based on the initial patch by Ben Lunt with some modifications:
using enum parameter, extra parser handler and cdrom handling not necessary,
TODO: hdimage and bximage code, harddrv and USB disk emulation, BIOS.
- Added new PCI chipset choice for the i440BX AGPset. Some basic work is done,
but AGP support is not present yet.
- Added new class for the "virtual" PCI-to-PCI bridge that should manage the
secondary bus (AGP). Since this device must appear with device number #1 at
the primary bus, it was required to change the PCI device numbers for the
i440BX case. Moved the PIIX4 module to device number #7. The presence of the
PCI base address regions now depends on the header type as expected.
- Since the Bochs BIOS cannot handle the modified PCI device layout, all tests
continued with an external BIOS designed for this chipset (GA-6BA_F1.bin).
This BIOS requires additional changes in some devices.
- ACPI: Return value 0 for some status registers and the GPI registers.
- CMOS: Since the PIIX4 supports a 256 byte CMOS RAM, prepared support for it
and enable it in case a 256 byte CMOS image is used.
- PCI: The device numbers for 4 slots starting at #8. The 5th slot could be
used for AGP when available.
take RAW_BYTES string out of bx_param_string_c into new param type bx_param_bytestring_c (better name, anybody?)
this is intermediate step, later it would be better to merge bx_param_string into generic template bx_param<type>
but bx_param_bytestring_cis not matching that concept (or probably will continue to inherit from bx_param<string>)
use new method do dump param tree during save/restore, GUI and text debugger and other places
significantly reduce code duplication over multiple modules
- Treat VGA extension name other than "none", "vbe" or "cirrus" as a VGA
compatible device plugin and try to load it.
- Added new plugin type PLUGTYPE_VGA for such a plugins (interally handled like
a core plugin).
- Added panic in devices init for the case no VGA compatible plugin is present.
- Added new method vga_redraw_area() that handles the non-VGA and null size
case. The specific method redraw_area() is called otherwise.
- Moved init_systemtimer() call from extension code to init_standard_vga().
- TODO: Implement VGA subsystem in the Voodoo code to test the new feature.
Voodoo Banshee 2D accelerator code needs to be written to make this really
useful.
latest BIOS images 32-bit and even 64-bit guest OS's are known to boot inside
of Bochs without hacking. This legacy hack could be removed after next release
if nobody complains.
- Using bochsrc option "load32bitOSImage" now causes a warning. It is not
maintained yet, not documented and we don't whether it is used or not.
I guess it was designed to boot a real 32-bit guest OS when the Bochs BIOS
wasn't able to do it.
- Added config option --enable-busmouse to all shortcut scripts. We have two
usable models present now (tested with Win95).
- Added warnings for currently not maintained features in the configure script,
the bochsrc sample and the user doc.
- Removed detection of deprecated bochsrc options "i440fxsupport" and
"vga_update_interval".
- Legacy bochsrc option "user_shortcut" is now deprecated.
- Removed deprecated configure option --enable-misaligned-sse from user doc.
- Updated some TODO items.
external program 'bxhub' (simulating a two port ethernet hub). It is based on
an old SF patch and it has been updated and extended:
- Windows support (tested with MinGW/MSYS and MSVC nmake).
- Command line arguments for 'bxhub' (base port number, MAC address, TFTP).
- Added support for DHCP, TFTP, ARP and ICMP echo (ping). It uses parts of the
code for the 'vnet' module with some additions from the former "slirp backend".
- TODO: code cleanup to reduce duplication, rewrite of the networking plugins
stuff similar to the work done with the sound drivers.
Prepared "biosdetect" option in the harddrv code.
TODO #1: Add support for a comma-separated list of BIOS options.
TODO #2: Implement support for at least "biosdetect=none" in the Bochs BIOS.
configuration, loading images). Cleaned up "romimage" option parsing and
prepared parameter "options" for the behaviour of the Bochs BIOS.
TODO: implement BIOS option "fastboot" to skip the boot menu prompt.
- waveout: added support for RIFF WAVE format and raw output. The formats
'voc' and 'wav' are detected by file extension, raw output is used otherwise.
- midiout: added support for raw midi output (no header, no deltatime).
The 'mid' format is detected by file extension, raw output is used otherwise.
- Added 'midiout' parameter to the global sound option to specify the device
if necessary. The related SB16 parameter now only specifies the output file.
- TODO: Rewrite of the sound configuration and output code to support dual
output (device and file).
implemented important CPU statistics which were used for Bochs CPU model performance analysis.
old statistics code from paging.cc and cpu.cc is replaced with new infrastructure.
In order to enale statitics collection in Bochs CPU:
- Enable statistics @ compilation time in cpu/cpustats.h
- Dump statistics periodically by adding -dumpstats N into Bochs command line
gui init and string paramter handler. The shortcut keys are now stored in an
array of BX_KEY* values in the gui object.
siminterface.h: Fixed some default return values.
- added new symbol BX_WITH_SDL2 and prepared build system
- TODO #1: add new option --with-sdl2 to configure script
- TODO #2: add new file sdl2.cc (porting seems hard to do - writing from scratch
might be better)
- added slirp.conf to NSIS script
- NSIS script now using HTML documentation path from 'install_win32' target
- Makefile: DLX Linux config file renamed to 'bochsrc.bxrc' for win32
- config.cc: bochsrc option removed with coming version
required an external binary and it couldn't be ported to Windows. Now the new
builtin and portable slirp support based on Qemu's implementation is almost
stable and all the 'vnet' DHCP and TFTP features have been ported to the new
slirp module.
TODO: rename all the "slirp_new" stuff to "slirp"
is almost a port of the Qemu 1.1.2 implementation. It has been tested successfully
on Linux and Windows (MinGW/MSYS). The networking module is currently called
"slirp_new", since the "slirp" backend module still exists.
TODO list:
- MSVC support (requires container_of() macro replacement)
- apply fixes and improvements from recent Qemu releases
- use our TFTP implementation to reduce code duplication
- check if we can share ARP and DHCP support with "vnet"
- add SMB support on Linux
- finally remove the slirp backend module support
usb device plugins. Loading the plugin means that the user wants to enable it.
Disabling the device on the command line and in the config interface is still
possible.
- fixed pluginlog init in non-plugin mode
- reduced logprefix length limit and use it for the related string parameter
- increase the device prefix size to 6
- TODO: change some more device prefixes
- If the runtime flag of a bx_list_c object is set, all it's items are set up
as runtime options.
- Set the runtime parameter for all top-level runtime-only lists. Setting up
each single parameter is no longer needed.
