249fcf9442 Set the device type correctly for all media types when parsing floppy options.
- Added helper function get_floppy_devtype_from_type().
- The floppy type option now accepts the value "none".
- Added parameter handler for "devtype" to handle the BX_FDD_NONE case.
- Cleaned up floppy options parser code.

b1c36691de Partly fixed floppy issues caused by previous commit. If device type is set to
"none" the dependent parameters cannot be set. That's why the bochsrc parser
needs to set device type first.
- Set initial device type of first floppy to '3.5" 1.44M'.
- Detect device type along with image type if necessary.
- TODO: fixes for media types like "1_44" and some more cleanup.

919d82b68e Next step of USB devices handling rewrite. Changed type of the device parameter
to bx_param_enum_c. Updated code to provide support for legacy syntax
(portX="device:option").

e00a5d0761 Started rewrite of the USB devices handling.
- Moved main option from the portX parameter to the optionsX parameter. Added
  new option "path" for the disk, cdrom and floppy devices, "ports" for the
  USB hub and "file" for the USB printer. The legacy syntax is still supported.
- Register USB device state after init() to ensure all options that may have
  effect on the save/restore list are applied.
- Report available devices on top of log file similar to hdimage, network and
  sound modules.
- Changed USB device type variable typein host controllers to int.
- Prepared improved usbdev_ctl init / exit implementation.
- TODO: Create list of USB devices dynamicly from available plugins.

535856833c Display library plugins list is now created dynamicly at startup instead of the
hardcoded one. In plugins mode now all plugins with PLUGTYPE_GUI can be used.
Added similar code for the case plugins are disabled. The macros
PLUG_get_plugins_count() and PLUG_get_plugin_name() can be used in both cases.

333afe3e4a Fixed some issues found with save/restore tests.
- BXRS_PARAM_BOOL macro should be used for bool type members only.
- Fixed usage of wrong BXRS macro for numeric member in usb_hid.cc.
- New PCI parameter "advopts" must be saved in config.
- FIXME: Bochs hangs at startup in restore mode.

6ad19a7716 Rewrite of the sound driver handling similar to the hdimage and networking
module code. Sound driver names are now stored as string constants instead
of hardcoded values. Available modules are detected at Bochs startup and stored
in a string array before initializing options. In the plugins case available
modules are read from the plugins list. If plugins are off, the registry of
bx_sound_lowlevel_c is used. Related changes similar to the hdimage and
network modifications.

Volker Ruppert
880ee1832a Some Bochs plugins support and VGA extension option changes.
- Changing VGA extension to "voodoo" did not work in the config interface.
  Moved plugin loading to the string parameter handler and added plugin
  unloading case.
- Unloading "voodoo" VGA plugin resets pluginVgaDevice to stubVga.
- pluginUnregisterDeviceDevmodel() now supports core plugins.
- Some other small plugin related changes.

74deb16b44 Since externally developed optional device plugins (AKA "user plugins") can be
loaded in bochsrc with "plugin_ctrl" or with their own name, the user plugin
option and the special cases for PLUGTYPE_USER are no longer needed. Updated
example patch to make it work with the latest SVN code.
2021-01-24 10:16:22 +00:00
Volker Ruppert
e5c68dd4ac Rewrite of the optional plugin control feature.
- Now that we know about all available plugins at startup, the bx_list_c object
  "plugin_ctrl" contains a fixed number of bx_param_bool_c objects representing
  the requested status (1 = load). It is verified at simulation startup.
- The config interface creates two text lists (textconfig) or list boxes (win32,
  wx) from it to show the remaining available and the loaded plugins. Loading
  and unloading is performed immediately and plugins may install / uninstall
  options in other menus / dialogs.
- Modified the "non-plugin" code to make the optional plugin control work very
  similar in this mode.

5ffb319df1 Rewrite of the disk image mode handling. Disk image modes are now stored as
string constants instead of hardcoded values. Available modes are detected at
Bochs startup and stored in a string array before initializing options. In the
plugins case additional modes are read from the plugins list. If plugins are
off, the hdimage_locator_c registry is used. Related changes in all parts of
Bochs that need the hdimage stuff.
TODO #1: Network and sound drivers could be handled in a similar way.
TODO #2: Make disk image mode detection work again in plugins mode.

6692664a3b Added helper function bx_split_option_list() to reduce code duplication.
It creates an array of strings from a string containing a comma separated list
of options. Now using this function for display library options, USB port
options and ROM image options.

aaf8c9d4e4 Removed "svga" display library designed for the obsolete Linux SVGALib.
The latest release is from 2001 and it will not work on modern Linux systems.
Parts of the SVGALib code have been moved to the Linux kernel and the X11 and
SDL libraries are using it as a video driver.

2045ead0ce Improved error handling of the user shortcut feature.
- Shortcut parser sets a flag in case of error.
- String parameter handler resets to old value if the new one is invalid.
- User button handler shows a message box if the parser signals an error.

c05cb5e1d7 Removed legacy "load32bitOShack" feature. In the early days of Bochs some hacks
were required to load a 32 bit OS. In the meantime Bochs has been made capable
of loading 32 and 64 bit OS's without hacking.

d51f6480a0 Some fixes for the "multiple NICs" support.
- 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.
2020-03-04 17:37:34 +00:00
Volker Ruppert
835a745215 Added experimental "multiple NICs" support (currently NE2000 only). Unlike the
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.
Related changes:
- removed SMF stuff for ne2k
- always convert device prefix to uppercase (ne2k uses NE2K0 ... NE2K3)
- removed unused BXPN values
- TODO: add multiple NICs support for the E1000

e7093e74d8 Started implementing the i440BX PCI/AGP chipset.
- 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.

e8d0e718f1 continue param tree changes
take RAW_BYTES string out of bx_param_string_c into new param type bx_param_bytestring_c (better name, anybody?)

d25e85c21a Preparing improved VGA extension support and some VGA / Cirrus cleanups.
- 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.

e1d8bedbb5 Added symbol BX_LOAD32BITOSHACK to disable this legacy feature. With the
latest BIOS images 32-bit and even 64-bit guest OS's are known to boot inside

bc1b1d4ed5 Continued release preparations:
- 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).

d6166344eb Added ethernet module 'socket'. designed to connect two Bochs instances with
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".

c8207c7a10 Some work on the soundfile 'driver' and the sound configuration.
- 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).

fee79a2837 Removed the "slirp backend" networking module from the Bochs sources. It had
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.

dfc71f8ae4 Applied patch for builtin "slirp" (user-mode networking) support. This version
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
