A quick fix would be simply enabling PCI cards but keep the agpgart restriction. The only change required would be changing the access type to PCI in the DMA registers. I think it should work but I don't have a PCI card to test with so I can't be 100% sure. > > Log message: > > Fixed GL_NV_texture_rectangle support. > > Any idea how tough it will be (or if it's possible!) to add support for > ARB_texture_non_power_of_two?

I suspect the hardware won't support it. The G400 specs say that no mipmapping and clamp only. Which are exactly the same restrictions that NV_texture_rectangle specifies. > > Log message: > > Texure environment updates: > > - Each texture unit has it's own environment color but we have only one > > FCOL register. > > - Move GL_BLEND handling to a separate function. > > - Remove unnecessary memcpy of TexState[0] to TexState[1].

I did look at the cvs logs and I think this stuff was there before XFree86 4.0. Isn't the pre 4.0 drm already incompatible with the current stuff? -- Ville Syrjälä [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ ------------------------------------------------------- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.
