the screen buffer in 8 bpp guest mode).

96f4c44cce Fixed Voodoo Banshee screen update issues and some other small changes.
Banshee TODO list:
#1: Fix display errors caused by incorrect implementation and find out the
    expected behaviour of the undocumented stuff.
#2: Make color depth > 8 work correctly.
#3: Screen resulution change not possible yet (only 640 x 480 works).
#4: Implement remaining 2D commands (line, polyline, polygon fill, stretchBlt).
#5: 3D core usablility, code cleanup, ...

c81df659c1 Some work on the Voodoo Banshee BitBlt code.
- Implemented ternary raster operations. With 3 binary input values we have 8
  possible combinations und the ROP code is the binary representation of the
  result table. Instead of implementing cascades of binary operations at byte
  level, we simply build a 3-bit value from D, S and P. This is the bit number
  of the ROP code to use as the result. This is performed for each bit of color
  data. We still keep the existing binary operations at byte level, since the
  code is faster for that case.
- Inplemented the "row #0 only" flag handling in pattern fill operations. This
  flags seems to have an undocumented effect on the source pitch of
  host-to-screen operations. This issue needs to be investigated.
- TODO: Some bits of the srcXY register seem to have an undocumented effect on
  host-to-screen operations, too.

7ad81ace40 Some work on the Voodoo Banshee emulation.
- Added basic support for the tiled desktop space. Win95 now starts building
  the desktop, but without icons and it is not yet usable in 16 bpp mode.
- Fixed 32 to 24 bpp format conversion in host-to-screen operations.
- Fixed some raster operations.
- Now allocate buffer for launch area writes dynamicly.
- Added error messages for undocumented features.

49885211ad Unified screen update code of all Voodoo models and prepared Voodoo 1/2 for
tile-based updates and screen update locking. Some related changes in the init
and save/restore code are also included. The main update code has been moved
from bx_voodoo_vga_c to bx_voodoo_c and the required parameters are set up
depending on the model. The BX_LOCK/BX_UNLOCK and SET_TILE_UPDATED stuff still
needs to be added in the 3D core. Currently a redraw_area() hack makes the
Voodoo 1/2 screen updates work as expected.

b25ec2adcf Some work on the Voodoo Banshee emulation.
- Fixes and optimizations in the BitBlt code.
- Added mutex for display updates and lock some register writes and the BitBlt
  methods during screen update.

205ac13582 Some work on the Voodoo Banshee emulation. Win95 with Banshee driver is now
almost usable in 8 bpp mode, but there are still issues (see below).
- Added basic support for pattern fill functions.
- Added some more ROPs (all S/D and P/D ones).
- Now using the ROP functions in rectangle, pattern and host-to-screen code.
- Several other related changes.
TODO:
- Implement remaining binary (P/S) and all of the ternary ROPs.
- Some Windows icons are still black or messy (e.g. start button) and screen
  are missing in some cases. Shutdown background is wrong, although the correct
  ROP is used.
- Cleanups and optimiations when the code is known to work as expected.

ca9120655b Some work on the Voodoo Banshee emulation.
- Moved basic BitBlt stuff from the Cirrus code to a separate header file to
  make it usable for the Voodoo Banshee, too.
- Rewrite of the screen-to-screen BitBlt code for the new ROP code.
- Calculate redraw parameters based on the screen start.
- Set "Banshee busy" bit in the status register when 2D is busy.
- Added some error messages for unimplemented features.

- Fixed hardware cursor bottom/right edge display bug.
- Started splitting 2D code in different methods (no functional changes).
- Added hardware cursor to save/restore list.

TODO #2: Voodoo code reorganization: base class with Voodoo core, one subclass
         for Voodoo1/2 and one for Banshee.

13d4f0ff65 Some work on the Voodoo Banshee emulation. Win95 boots now with Banshee driver
in 8 bpp mode, but it's not yet usable (no cursor, no text). List of changes:
- Added AGP/CMD/Misc register handling (CMDFIFO #0 is now usable).
- Started work on 2D register handling ("Rectangle fill" command implemented).
- Added Banshee specific code in redraw_area().
- Writing to VGA DAC registers also modifies the Banshee CLUT.
- Banshee now indicates that no TV-out and video-in device is connected.
- Some other related fixes and improvements.

d7ab113a95 Improved video clock handling for the retrace timing emulation.
- Added VCLK array and removed hardcoded values.
- Added new method get_crtc_params() to retrieve htotal and vtotal values.
- Cirrus: Set up VCLK registers with default on reset (TODO: VGABIOS should do
  that when setting video mode).
- Voodoo Banshee: Set up VCLK #3 when writing to pllCtrl0 register. VCLK #0 and
  #1 are VGA compatible and VCLK #2 is fixed 50 MHz. Fixed maximum resolution
  based on PLL section of the spec.

7bd6e6c7c2 Removed all of the pre-defined rasterizer functions and replaced it by a single
function. I guess the old stuff should be a speed optimization, but I don't see
a difference with the new code. The simulation output is also still the same.
Now Bochs compiles much faster with Voodoo support enabled and the binary is
much smaller. This patch has been written by Luigi B.

e2245d98d3 Some work on the Voodoo Banshee emulation.
- Banshee Memory layout implemented (AGP/misc and 2D register behaviour not
  implemented yet). Now Win95 with Banshee driver can boot in standard VGA mode.
- Fixed memory allocation: Banshee has 16 MB shared LFB / TMU memory.
- Some work on save/restore support.
- Renamed Banshee VGA register handlers.

35684fa0f5 Started implementing the Voodoo Banshee display adapter based on the existing
"Voodoo VGA" framework. Most of the work is still to do.
- Added Banshee specific PCI write handler and related stuff. The device is
  initialzed properly by the Bochs BIOS (mem, lfb, rom and i/o).
- With Banshee specific VGA BIOS it passes the init stage and boots properly
  to DOS. Parts of the init code coming from file "voodoo.h.txt" (part of the
  original patch).
- Standard VGA modes are all usable (using the Bochs VGA core).
- VBE graphics modes with 8, 16, 24 and 32 BPP are usable (VBE drawing code is
  mostly copy&paste from the Bochs VBE code. DAC 6/8 bit switch is present.
- TODO list:
  - Voodoo Banshee memory layout (registers, 2D, 3D, LFB, textures)
  - 2D graphics engine must be written from scratch
  - interaction between new device and existing 3D core
  - non-VGA mode (Voodoo model "banshee" without VGA extension "voodoo")
  - save/restore support, move Banshee stuff to separate file, ...

2b91dabfe5 Added new VGA extension choice "voodoo" to test the new VGA extension code. It
currently only implements an ISA standard VGA adapter with the selected Voodoo
model as it's extension. The methods of the "Voodoo VGA" device only call the
required methods of the Voodoo or VGA core.

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.

6dba96d10a Some changes related to the PCI ROM handling.

610cec209d Rewrite of the VGA/Cirrus code to reduce code duplication.
- Moved VGA timer handler to the VGA core and handle the non-VGA case there.
  It calls the specific update() code and finally bx_gui->flush().
- Moved the VGA update frequency parameter handler and the refresh_disply()
  method to the VGA core.
- Store the VGA extension parameter in the VGA core.
- Voodoo: Fixed graphics snapshot.
