Voodoo GFX Emulation
Hey Toni,
Would it be possible to use the Voodoo1 / 2 Emulation that Dosbox and KVM(QEMU) use? I know they were talking about emulating a Voodoo3 soon. |

Well..... The Voodoo2 and 3 3D hardware is really quite similar so probably its not impossible to extend the existing code to support a Voodoo3.
Hoooowever! Only the 3D hardware is not going to get you anywhere, the 2D part is also needed to get a usable desktop which is not implemented anywhere and of course the Voodoo2 does not have this component at all. So its far from just a matter of adapting some existing code. |

I didn't check but it probably also lacks blitter emulation which is 100% required. At least last time I checked Cirrus Logic emulation was the only one that was complete.

How much hardware acceleration features do existing P96/CGX drivers actually use?

Actually, the Amiga Avenger Warp3D drivers do not use the 2D or VGA parts (registers and config) of the gfx board that I am aware of (P96 RTG would use the 2D part but it should be possible to put the 3D over another existing 2D standard). The texture uploading interface is probably used of which I didn't get far enough to figure out how that works. I have working modified W3D drivers and documentation. The Voodoo 3 Avenger W3D driver is compatible enough to work on the Voodoo 4 and 5 although most new features don't work. |
