Re: Accessing AGP

What the command verifier does is that it lets commands thrugh that is knows: 1. Only accesses the 2D-engine or Mpeg engine through writes. (Other areas are blocked). 2. Does not attempt to fetch memory contents from system memory. 3. Does not attempt to fetch memory contents from AGP memory that

This has just been implemented in the Unichrome driver, and I'm not sure wether it's the best or most appopriate way to do it but it works as follows: 1. The Mesa driver fills a "malloced" system memory buffer with vertex data. 2. The Mesa driver then calls the DRM through a via-specific IOCTL.

Accessing AGP

Hi all, Can someone more knowledgable explain to me how to properly access AGP space from within Mesa driver ? What I want to do is to copy vertex data (i.e. coordinates, colors, etc) into an array in AGP space so that R300 engine can fetch it from there. Ideally, I would be able to tell Me
