      There is a sticky... I just can't edit the damn thing any more

      and talking of that. i thought that there would be a VDPAU state tracker (even for ati cards) to resolve the discussion about flash-y things.
      Gallium3D is a new low-level API to encapsulate the functionality of a modern shader-based GPU and allow the same functionality to be shared by multiple high-level APIs (state trackers). First step is to get the existing high level APIs running over Gallium3D drivers.

      Mesa implements an OpenGL-like API and has an existing HW driver layer. For each GPU, common mesa code makes up 90-95% of the "Mesa driver" while the HW-specific driver code provides the other 5-10%. Gallium3D drivers replace the HW driver layer (only used for Mesa) with a new driver layer useable by other state trackers, but does not replace the other 90-95% of Mesa.

      3D graphics operations used to go through the X server, then the X server would call Mesa. Running 3D calls through the X server allowed X to manage windows and Mesa to draw into those windows, but with some overhead. The Direct Rendering Infrastructure (DRI) was developed to let applications call Mesa directly and have Mesa check with the X server to see if the target window had moved since the last call. The Direct Rendering Manager (DRM) is the kernel driver which makes up part of the Direct Rendering Infrastructure.

      DRI is a protocol; DRM is a driver component.

        I second that, my friend.
