77cc12cce5 Added support for reading VGA latches using CRTC register 0x22 (undocumented
for original VGA, documented for Cirrus and Voodoo Banshee).

69695bfd67 Prepared the Banshee code for the planned LGPL'd VGABIOS with 3dfx Voodoo
support. The VGABIOS image will be compiled for Banshee PCI and this code
modifies the PCI data for the Voodoo3 and AGP models.

7aa5eb7a51 Some changes for correct vertical frequency reporting on mode switch.
- vgacore: method get_crtc_params() now returns selected video clock value.
- banshee: now using selected video clock instead of hardcoded VCLK #3.
- cirrus: added vertical frequency to mode switch BX_INFO.

857c3be2ba Some work on the Voodoo Banshee code.
- Moved setup of default i/o register values to reset().
- Set up strapInfo register bits in init().
- Don't overwrite readonly bits in miscInit1 register.
- Set up subsystem ID in VGABIOS ROM in case it's > 32k (doesn't exist yet).
- Copy subsystem ID from ROM to PCI config registers in reset().

25e725a23c Makefile dependency updates
- Don't include paramtree.h in siminterface.h to get rid of duplicates
  in a lot of Makefile dependency lines.
- Regenerated Makefile dependencies in iodev and affected subdirectories.
- FIXME #1: including debug.h causes duplicate entries of config.h and osdep.h.
- FIXME #2: cpudb.h appears in most of the iodev* dependencies, but only needed
  by config.cc and the cpu class.

a2cf072751 Some cleanups in the plugins code. 2021-03-07 16:01:39 +00:00

4dd5816108 Some changes in the Bochs plugins code.
- Changed variable type of the plugin_t "type" member from enum to Bit16u.
- Added support for returning device flags with the new mode PLUGIN_FLAGS in
  the plugin entry functions. It is currently only used for devices that can
  be connected to a PCI slot.
- Code cleanup in core device plugins: checking type no longer necessary.
- The "non-plugin" mode now also uses the "loadtype" member of plugin_t.

TODO: Change PCI slot options to bx_param_enum_c and build the choices list
using the new capabilities of the plugin API.

8aaf9d858e Changed type of vga and svga_cirrus plugins to PLUGTYPE_VGA. Modified vga
extension option init to make this work correctly. The choices "none" and "vbe"
load the vga plugin, "cirrus" loads svga_cirrus.

0d425037df Improved plugin type detection at Bochs startup.
- Added special mode to all plugin entry functions that returns the plugin type.
- The plugins search function now temporarily loads all available plugins and
  reads the plugin type using the new mode PLUGIN_PROBE.
- Added "loadtype" to the plugin structure to store the type used for plugin
  loading (currently only the voodoo plugin provides two types).

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.

8db0a2b001 Replaced the plugin init / fini functions with one single function called
plugin_entry(). The additional boolean argument "init" is used to select the
requested action. The entry points still have unique names for compatibility
with the "non-plugin" compilation. Added macros for setting up these names
(e.g. PLUGIN_ENTRY_FOR_MODULE for device plugins).

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.

b94fff0501 Implemented new text update API in the vncsrv gui and console cursor fix.
- Now the vncsrv gui supports the VGA features split screen and h/v pel panning.
- Fixed new API cursor blinking in the gui console.

6202244991 Implemented a new text update API in the common gui code and enabled it for RFB.
- Now using text_update_common() for the new text update API in addition to the
  graphical text snapshot feature.
- Drawing to snapshot buffer moved to new method draw_char_common().
- A gui using the new text update API only needs to implement the new method
  draw_char(). The method set_font() is optional and it can be used to update
  font bitmaps / pixmaps.
- Modified the RFB gui to use the new API. Now the VGA features split screen
  and h/v pel panning are supported by the RFB gui. The legacy text_update()
  method is now empty but it must be present for compatiblity.
- TODO: Implement new API in some other guis to reduce code duplication.

- Added BX_ERRORs for unimplemented unaligned access to i/o registers.
- Access to the unimplemented YUV address space now causes BX_ERROR.
- Removed some TODO comments.

1d0efc734f Some work on the Voodoo Banshee emulation.
- New attempt to fix the host-to-screen bitblt issue with monochrome source.
  The specs are wrong at this point. The rules for calculating the real source
  pitch are still unknown. These hacks should fix most the glitches.
- Added source colorkeying support for host-to-screen blt with pattern.

Volker Ruppert
98e10e0bab Some changes in the Voodoo code.
- Banshee: Added colorkey support for host-to-screen blts without pattern.
- Clearing base address registers in reset is not okay. Maybe we have to
  unregister i/o and memory regions here. This affects other devices, too.
- Some other small changes and typo fixes.

feature of packet type #5. Added some W2 cases for texture writes, modified
