6adba30922 Some small changes for the Voodoo Banshee emulation.
- Use the CMDFIFO wakeup on vertical retrace only for the 3D mode.
- Report screen mode change (2D, 3D, mixed).
- Added BX_ERRORs for currently unsupported pixel format conversion.

b30ec133a3 Some work on the Voodoo Banshee emulation.
- Only continue bitblt operation if width and height is > 0 after clipping.
- Temporary hack: Processing CMDFIFO packets directly after completion fixes
  some display issues (FIXME: 3D mode should work like Voodoo2).

96f269d453 Some work on the Voodoo Banshee emulation.
- Handling variable 'gui_update_pending' like Voodoo 1/2 fixes 3D display
  flicker. Simplified first stage of the update() code. Some 3D display issues
  still need to be investigated.
- Added missing 16-bit write support in 3D memory space.
- Added separate method for linear FB writes und use it for CMDFIFO packet type
  5, destination code 0. Added minimal "byte disable" support in this code.

47f3936de2 Some work on the Voodoo Banshee emulation.
- Added Banshee specific registers in register_w() since they use the same
  addresses as the Voodoo2 CMDFIFO config registers in register_w_common().
  Now the fullscreen 3D mode is basicly working. The display flickers sometimes
  and the desktop is possibly unusable after leaving 3D mode. This may be
  caused by the still incorrect CMDFIFO implementation.
- Split the host-to-screen method in two ones: one for the pattern case (ternary
  ROPs) and one optimized for the standard case (binary ROPs).
- Improved the foreground/background color handling for bitblt operations.

df6246601e Some fixes for the Voodoo Banshee emulation.
- Always check if CMDFIFO is still enabled in the FIFO thread loop.
- Fixed offset for 3D register access (3D still not usable).
- Apply FBI mask when accessing memory in tiled desktop mode to avoid segfault.
- Added support for 16-bit writes to LFB.
- Don't access Voodoo2 CMDFIFO in Banshee mode.
- Set up the correct chipmask for Banshee (it has only one TMU).
- Fixed CMDFIFO enable message (using index #0 and #1).

dd694757f4 Attempt to fix the calculation of the source pitch and the total amount of
dwords required for host-to-screen operations. There are no related error
messages in the log when I test 8, 24 and 32 bpp modes. There are still display
errors caused by buggy code, incorrect CMDFIFO implemenation or undocumented
features. The 16 bpp mode is still unusable possibly caused by CMDFIFO. 3D mode
testing cannot start before this mode is okay.

5698c69744 Attempt to fix the CMDFIFO hole count feature based on the code from voodoo.h.txt.
The Voodoo2 works fine with it. With the Banshee model only the 16 bpp mode is
not usable yet. This issue needs to be investigated.
