That's how the networking drivers work and they may be the fastest drivers in the system. But, it has not been coded for AGP so nobody knows for sure. It has to be faster though, having the CPU do the copy will cause the TLB cache to be flushed as you walk through all of the pages. Having the GPU do the copy is even worse since it moves across AGP. We have bigger problems to chase. Plus implementing it this way probably has a bunch of architecture specific problems I don't know about. But I'm sure it would work on the x86. After we get X on GL up on mesa-solo I can look at changing the texture copy code. -- Jon Smirl [EMAIL PROTECTED] ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
