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 is outside the user-mappable range (textures).
Frame-buffer memory is considered open territory, as is the user-mappable part of AGP-memory. Note that the AGP command buffers must NOT reside in the user-mappable parts of AGP-memory.
I see. Thank you !
Is it true then that on Unichrome all vertex data is "immediate" - i.e. embedded in the command stream ? This is as opposed to saving it in a separate array in AGP memory and only issuing a command to load pointers to it via command stream.
