- Zero out voodoo device state in init().
- Added the CMDFIFO state to save/restore list.
- Added CMDFIFO register handling in read/write functions.
- Added new function cmdfifo_put().
- TODO: CMDFIFO thread.
- Fixed normal register access in CMDFIFO mode.
- Implemented cmdFifoBaseAddr register behaviour.
- Write CMDFIFO data to FBI memory (has no effect yet).
- Changed some log messages to BX_DEBUG.
- Report unimplemented Voodoo2 registers.
- TODO: Add FIFO thread to process the CMDFIFO data.
valid. The hRetrace value can be set now, since Bochs no longer crashes.
TODO: Implement enough of the FIFO stuff to make the Win9x driver for the
Voodoo2 work.
- 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).
- Since we are using the virtual timer, so we have to read time_usec()
from it, too (TODO: realtime mode is hardcoded, maybe add an option).
- Voodoo1 and Voodoo2 have different timing register widths.
- Fixed vertical retrace value returned by get_retrace().
- Prepared separate hvRetrace register (TODO: hRetrace).
- fixed clock values (assigned to wrong model)
- LFB read/write: don't limit y values to 1023 (4MB now usable this way)
- additional Voodoo2 fbiInit* register writes now handled like the Voodoo1 ones
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.
