What do you mean by "hardware TexSubImage"?
Maybe I'm reading it wrong but looking at these texbubimage functions, they all copy out a the part of the texture to use, what I'm wondering is if there is a way to tell the card to do that.
I believe a DMA transfer is used to move texture data from main memory to the card. What else do you have in mind?
Also, atm Mesa falls back to software for vertex arrays, is it possable (and is it planned) to push the vertex arrays to the r200 instead of falling back to software. Is the DRM missing somthing that has prevented this from happening already?
Typically, OpenGL's vertex arrays have to be translated into DirectX-style arrays of vertex structures. That's done by Mesa / the driver. Thereafter, the gfx hardware is doing the vertex processing/rendering. I wouldn't call that a software fallback since I don't think the gfx cards can do the SOA->AOS conversion anyway.
The DRM doesn't figure into this.
Keith's the expert on this stuff but he's on vacation for 2 weeks.
