- Simplified register writes from CMDFIFO using new methods in the new classes.
- Started work on reset() and continued work on save/restore support.
- Mention the Banshee model in the Bochs documentation.
bx_voodoo_base_c that contains the shared code and the new classes
bx_voodoo_1_2_c and bx_banshee_c with the specific implementations. There are
not functional changes yet. TODO: The Banshee specific stuff could be moved to
separate files, but should still remain in the same plugin as Voodoo 1/2.
- 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.
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.
- prepared hRetrace value implementation (cannot be enabled yet, since the
driver passes this test and gets confused in next stage (segfault).
- Detect CMDFIFO access (not present yet).
- Report disabling Voodoo graphics mode.
- TODO #1: Fix Voodoo2 to make it usable.
- TODO #2: Split update code and drive gui screen updates from the VGA timer
(finally remove new realtime option again).
is based on a patch originally designed for DOSBox. Currently only the Voodoo1
adapter model can be emulation. The emulation is currently slow, but we intend
to clean up and optimize the code. Running the 3D engine in a separate thread
is also planned. To compile with Voodoo support the configure option
"--enable-voodoo" must be used. Then the device can be activated with
"plugin_ctrl: voodoo=1" in bochsrc or on the command line. The device will be
assigned automatically to a PCI slot unless you do that manually. A specific bochsrc
option to select the adapter model will be added when the code has support for it.
